Factors and outcomes associated with corneal edema and Haabs striae in primary congenital glaucoma. J AAPOS 2024; 28:103860. [PMID: 38442850 DOI: 10.1016/j.jaapos.2024.103860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 12/09/2023] [Accepted: 12/16/2023] [Indexed: 03/07/2024]
Abstract
PURPOSE To identify specific factors and outcomes associated with corneal edema and Haabs striae in primary congenital glaucoma (PCG). METHODS The medical records of patients with PCG from 2011 to 2023 with >3 months' follow-up were reviewed retrospectively. Preoperative details and final outcomes were compared between eyes with and without corneal findings. The right eye of bilateral cases and the affected eye in unilateral cases were included. RESULTS A total of 58 patients (104 eyes, 69% male) underwent initial angle surgery at an average age of 297 ± 368 (median, 134) days. Corneal edema and Haabs striae were present preoperatively in 72 (69%) eyes of 41 patients and 68 (65%) eyes of 39 patients, respectively. Patients with corneal edema presented at a younger age (P < 0.0001) and with shorter axial length (P = 0.01) than those without edema. Univariate analysis showed that corneal edema was associated with worse visual acuity at final follow-up (OR = 4.4; 95% CI, 1.2-25.3). Patients with Haabs striae were older than those without striae (P = 0.04). After angle surgery, corneal edema was present at 1 month in 71% (95% CI, 52-84), at 2 months in 26% (95% CI, 12-42), at 3 months in 16% (95% CI, 6-30), and at 1 year in 3% (95% CI, 0-13). Corneal opacification did not resolve in 4 eyes of 3 patients after >4 years of follow-up. CONCLUSIONS In our study cohort, corneal edema resolved in the majority of PCG cases within 2-3 months of initial angle surgery but was associated with younger age at presentation and worse visual acuity at final follow-up.

Long-term Outcomes in Patients Undergoing Surgery for Primary Congenital Glaucoma between 1991 and 2000: A Single-Center Database Study. Ophthalmology 2023; 130:1162-1173. [PMID: 37454696 DOI: 10.1016/j.ophtha.2023.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2023] [Revised: 06/27/2023] [Accepted: 07/10/2023] [Indexed: 07/18/2023] Open
Abstract
PURPOSE To estimate the long-term surgical and visual outcomes in patients with primary congenital glaucoma (PCG) who completed at least 20 years of follow-up. DESIGN Retrospective study. PARTICIPANTS Two hundred twenty eyes of 121 patients undergoing surgery for PCG between January 1991 and December 2000 and who returned for a follow-up visit from January 2021 through January 2022. METHODS Retrospective review of medical records of patients who underwent primary combined trabeculotomy-trabeculectomy (CTT) without mitomycin C as an initial procedure. Success was defined as complete when intraocular pressure (IOP) was ≥ 6 mmHg and ≤ 21 mmHg without glaucoma medication and as qualified when up to 2 glaucoma medications were required. Failure was defined as uncontrolled IOP with more than 2 glaucoma medications, need for a second IOP-lowering procedure, chronic hypotony (IOP < 6 mmHg on 2 consecutive visits), or any sight-threatening complication. A mixed-effects model using maximum likelihood estimation was used in estimation of eye-based variables and to make comparisons between different visits. Kaplan-Meier survival analysis was used to estimate the probabilities of surgical and functional successes. Cox proportional hazards regression using sandwich clustered estimation was used to evaluate risk factors for failure and poor visual outcome. MAIN OUTCOME MEASURES Primary outcome measure was the proportion of patients who demonstrated complete success over the 20-year follow-up. Secondary outcome measures included rate of surgical failure and need for reoperation for glaucoma, visual acuity, refractive errors, risk factors for poor outcome, and complications. RESULTS Kaplan-Meier survival analysis revealed 1-year, 10-year, and 20-year complete success rates of 90.7%, 78.9%, and 44.5%, respectively. In univariate analysis, surgical failure was higher among patients with any additional non-glaucoma intraocular surgery. None of the clinical parameters were associated significantly with failure in multivariable analysis. Overall, the proportion of eyes with good, fair, and poor visual outcomes was 33.2%, 16.4%, and 50.4%, respectively. Myopia was seen in 68.9% eyes. Twenty-eight eyes of those who underwent primary CTT (14.4%) required second surgery for IOP control. No significant intraoperative complications occurred. Six eyes required enucleation because of painful blind eye. CONCLUSIONS In this large cohort of patients with PCG, CTT is a useful procedure. It provides good IOP control and moderate visual recovery that remained over a 20-year follow-up after surgery.

Abstract
The basic pathophysiology of all childhood glaucoma results from impaired outflow through the trabecular meshwork. Anterior Segment Dysgeneses (ASD) are a group of nonacquired anomalies associated with secondary developmental glaucoma, characterized by impaired development of the structures of the anterior segment. Many genes impact the development of the anterior segment. The cause of the development of the abnormalities is thought to be multifactorial. Molecular research has helped our understanding of the molecular basis of ASD and the developmental mechanisms underlying these conditions. Identifying the genetic changes underlying ASD has gradually led to the recognition that some of these conditions may be parts of a disease spectrum rather than isolated anomalies. The characterization of the underlying genetic abnormalities responsible for glaucoma is the first step toward developing diagnostic and screening tests, which could identify individuals at risk for disease before irreversible optic nerve damage occurs. It is also crucial for genetic counseling and risk stratification of later pregnancies. It also aids prenatal testing by various methods allowing for effective genetic counseling. This review summarizes various ocular and systemic conditions that result in secondary developmental glaucoma and provide an overview of the phenotypes, the diagnosis and principles of management of the various disorders.

Approach to primary congenital glaucoma: A perspective. Taiwan J Ophthalmol 2023; 13:451-460.

Abstract
Primary congenital glaucoma (PCG) occurs worldwide and has a broad range of ocular manifestations. It poses a therapeutic challenge to the ophthalmologist. A proper diagnostic evaluation under anesthesia is advisable for all children who do not cooperate for an office examination. Medical therapy only serves as a supportive role, and surgical intervention remains the principal therapeutic modality. Angle incision surgery such as goniotomy or trabeculotomy ab externo is the preferred choice of surgery in the Caucasian population. Primary combined trabeculotomy-trabeculectomy with or without antifibrotic therapy is the preferred choice in certain regions such as India and the Middle East where the disease usually presents with severe forms of corneal edema along with megalocornea. In refractory cases, trabeculectomy with antifibrotic therapy or glaucoma drainage devices are available options in the armamentarium. Cycloablative procedures should be reserved for eyes with poor visual potential. Myopia is common among children with PCG, and appropriate optical refractive correction in the form of glasses or contact lenses should be provided. Amblyopia therapy should be instituted to ensure overall visual development in the early developmental years. Low-vision rehabilitation services should be provided to children with vision impairment. Long-term follow-up is mandatory and carers of children with PCG should be counseled and educated about this need. Regardless of the visual outcomes, clinicians should emphasize the need for education of these children during the clinic visit. The overall goal of the management should be to improve the overall quality of life of the children with PCG and their carers.

CYP1B1 and MYOC variants in neonatal-onset versus infantile-onset primary congenital glaucoma. Br J Ophthalmol 2023; 107:227-233. [PMID: 34526297 DOI: 10.1136/bjophthalmol-2020-318563] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Accepted: 09/01/2021] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To compare CYP1B1 and MYOC variants in a cohort of neonatal-onset (NO) and infantile-onset (IO) primary congenital glaucoma (PCG). METHODS This prospective observational study included 43 infants with PCG (14 NO and 29 IO) presenting between January 2017 and January 2019 with a minimum 1-year follow-up. CYP1B1 and MYOC genes were screened using Sanger sequencing with in-silico analysis of the variants using Polymorphism Phenotyping v.2 and Protein Variation Effect Analyser platforms. Allelic frequency was estimated using Genome Aggregation Database (gnomAd). Disease presentation and outcome were correlated to the genetic variants in both groups. RESULTS Babies with CYP1B1 mutations had more severe disease at presentation and worse outcomes. Six of 14 (42.8%) NO glaucoma and 5 of 29 (17.2%) IO harboured CYP1B1 mutations. Five of six babies in the NO group and three of five in the IO group harboured the variant c.1169G>A, [p.R390H]. They required more surgeries and had a poorer outcome. On in-silico analysis c.1169G>A, [p.R390H] scored very likely pathogenic. Two patients in the IO group who had the c.1294C>G, [p.L432V] variant had a good outcome. Five of 14 NO-PCG and 8 of 29 IO-PCG harboured the variant c.227G>A, [p.R76K] in the MYOC gene, which was scored benign by in-silico analysis, and was also found in 2 of 15 normal controls. CONCLUSIONS Patients with CYP1B1 pathogenic variants had a poorer outcome than those without. We found more NO PCG babies with CYP1B1 mutations compared with IO PCG. This may be one of the reasons for NO PCG having a poorer prognosis compared with IO PCG.

Abstract
PURPOSE To evaluate the long-term outcomes of glaucoma management in patients with congenital ectropion uveae (CEU) over a period of three decades at a single large referral tertiary eye care center. METHODS Retrospective chart review of all patients with CEU treated surgically from 1990 to 2019 was performed. Primary combined trabeculotomy-trabeculectomy (CTT), trabeculectomy with and without mitomycin-C (MMC) (0.2 mg/mL for 1 min) and transscleral cyclophotocoagulation (TSCPC) were performed. Intraocular pressure (IOP) ≥6 and ≤16 mmHg without medications was considered as complete success and IOP≤ 16 mmHg with the use of upto 2 medications as qualified success. RESULTS A total of 26 eyes of 21 patients were identified with a median age of 7 years (range, 6 days to 19 years) at the time of glaucoma surgery. Median follow-up was 51.1 months (range, 7-244.6 months). Primary CTT was performed in 17 eyes (65%), trabeculectomy in 5 eyes (19%) with application of MMC in 2 eyes, and 3 eyes (12%) underwent TSCPC. One painful blind eye (4%) underwent evisceration. Mean IOP reduced from 30.8 ± 7.6 mmHg on a mean of 1.3 ± 0.8 glaucoma medications preoperatively to a mean IOP of 15.2 ± 5.9 mmHg (P < 0.0001) on a mean of 0.2 ± 0.5 medications postoperatively at final follow-up (P = 0.0009). Complete success was achieved in 20 eyes, and qualified success in 2 eyes. CONCLUSIONS CTT is a safe and efficacious primary procedure for management of early-onset glaucoma in CEU. Trabeculectomy with or without adjuvant MMC is a viable second line of treatment in late-onset glaucoma with CEU for IOP control.

Abstract
PURPOSE To evaluate the long-term visual and surgical outcomes, and associated risk factors for poor outcomes in patients with primary congenital glaucoma (PCG). METHODS Retrospective review of medical records of children who underwent combined trabeculotomy-trabeculectomy (CTT) without mitomycin-C as the first surgical procedure by a single surgeon between January 1990 and December 2010. Success was defined as intraocular pressure (IOP) <16 mmHg without (complete) or with (qualified) one glaucoma medication. We used the WHO criteria of vision loss to categorize the levels of vision impairment (VI). For purposes of statistical analysis, we randomly chose one eye of patients for bilateral PCG and affected eye in unilateral PCG. RESULTS The cohort included 653 consecutive PCG patients (1128 eyes; mean age, 26 months), of whom 475 (73%) underwent simultaneous bilateral CTT. Kaplan-Meier survival analysis revealed 1-, 5-, 10-, 15-, and 19-year complete success rates of 92.6% (n = 372), 75.5% (n = 173), 55.9% (n = 72), 44.7% (n = 19), and 21.6% (n = 3), respectively. Multivariate analysis revealed independent associations between failure, preoperative corneal clarity, and prior glaucoma surgery. Mean follow-up was 41 ± 51 months (range, 6 months to 19 years; median, 1 year). Of the visual acuity (VA) data in the affected eyes obtained at last follow-up (n = 333, 51%), seventy-four patients (22%) had VA of ≥6/12. Of the remaining 259 patients, 18 (7%) had mild VI, 87 (34%) had moderate VI, 58 (22%) had severe VI, and 96 (37%) were blind. No serious complications were noted. CONCLUSIONS Primary CTT may be safely employed to control IOP and may provide long-term benefits in PCG patients.

Abstract
PURPOSE To evaluate long-term results of glaucoma surgery in newborn and infants with glaucoma. METHODS Seventy-nine eyes of 52 children (age: 3 weeks-15.3 years) with primary congenital or secondary glaucoma treated between 2015 and 2017 were included. The median follow-up time was 3.9 years. Conventional probe trabeculotomy, 360° catheter-assisted trabeculotomy, filtering and cyclodestructive surgery were compared. Strict criteria for surgical success were applied: Complete surgical success (IOP below target IOP, no further surgery) and incomplete surgical success (additional surgery allowed) were analyzed, and IOP at baseline and last follow-up was compared. RESULTS Intraocular pressure (IOP) was significantly reduced in primary congenital (preoperative IOP: 27.8 ± 7.5 mmHg vs. postoperative IOP: 14.2 ± 4.5 mmHg) and secondary glaucoma (preoperative IOP: 29.2 ± 9.1 mmHg vs. postoperative IOP: 16.6 ± 4.7 mmHg). 90% of all eyes reached target IOP with or without medication allowing for additional surgeries. As first surgery, 360° catheter-assisted trabeculotomy had a tendency to higher surgical success than other surgical approaches, while cyclodestructive procedures had lowest. CONCLUSIONS We found very promising surgical results in our childhood glaucoma patient group. Surgical success in both congenital and secondary glaucoma was high.

Abstract
India is a culturally and geographically diverse nation. Its vast demographic nature does not allow a single definition for any of the given medical conditions in its territory. One important clinical condition which has created an uproar in the rest of the world is myopia. Its cause, prevalence, etiopathogenesis and other factors are being explored constantly; however, data with respect to Indian subcontinent are genuinely missing. Hence, in this review, we enumerate the country’s myopia journey from last 4 decades. The epidemiology, genetics, ocular/systemic association, quality of life, imaging, and management in myopia with necessary future directives are discussed to augment the overall management in future.

Abstract
To quantify the results of childhood glaucoma treatment over time in a cohort of children with different types of childhood glaucoma. A retrospective cohort study of consecutive cases involving children with primary congenital glaucoma, primary juvenile, and secondary juvenile glaucoma at the Childhood Glaucoma Center, University Medical Center Mainz, Germany from 1995 to 2015 was conducted. The main outcome measure was the long-term development of intraocular pressure. Further parameters such as surgical success, refraction, corneal diameter, axial length, and surgical procedure in children with different types of childhood glaucoma were evaluated. Surgical success was defined as IOP < 21 mmHg in eyes without a need for further intervention for pressure reduction. A total of 93 glaucomatous eyes of 61 childhood glaucoma patients with a mean age of 3.7 ± 5.1 years were included. The overall mean intraocular pressure at first visit was 32.8 ± 10.2 mmHg and decreased to 15.5 ± 7.3 mmHg at the last visit. In the median follow-up time of 78.2 months, 271 surgical interventions were performed (130 of these were cyclophotocoagulations). Many (61.9%) of the eyes that underwent surgery achieved complete surgical success without additional medication. Qualified surgical success (with or without additional medication) was reached by 84.5% of the eyes.

Abstract
Purpose The aim of this study was to describe the effectiveness of goniotomy for childhood glaucoma in Indian eyes. Methods Consecutive patients with pediatric glaucoma who underwent goniotomy between July 2017 and June 2020, in a single center in Northwest India were prospectively analyzed. Goniotomy was done as a primary procedure or a re-do surgery of the untreated angle in failed filtering surgery. Success was defined as intraocular pressure (IOP) ≦18 mm Hg with or without 2 topical medications. Results A total of 172 eyes of 126 children underwent goniotomy during this period (37.9% of all pediatric glaucoma surgeries). Goniotomy comprised 132 of 211 (62.5%) primary pediatric glaucoma surgeries and 40 of 243 (16.5%) re-do surgeries. 145, 112, and 54 eyes had a six months, 1-year and 2-year follow-up, respectively. At 1 year, success rates in Primary Congenital Glaucoma (PCG) were 79.7% for primary surgery and 68.4% for re-do surgery. For non-PCG eyes, the success rate was 62% at 1 year. Among PCG subgroups, infantile and newborn glaucoma had 87.5% and 57.1% success rates, respectively. On logistic regression analysis, lower baseline IOP and lesser axial length at presentation were significantly predictive of successful outcomes (P = 0.03 and P = 0.02, respectively). At 1 year, in the primary surgery group, 50% had good vision (better than logMAR 0.5), 28.9% had moderate (better than LOGMAR 1.0) and 20% had severe visual impairment. There were no significant intraoperative or post-operative complications. Conclusion Goniotomy appears to be an effective surgery for childhood glaucoma in Indian eyes. Being minimally invasive, it obviates the need for conjunctival and scleral dissection and antifibrotic agents.

Abstract
Purpose To assess the long-term visual outcomes of children with PCG, irrespective of the type of surgical procedure, and to create visual acuity curves to help in predicting the development of visual function in these patients. The secondary aim is to identify associated factors for visual decline or loss, highlighting differences between neonatal and infantile subgroups. Methods The medical records of pediatric glaucoma patients from 1996 to 2017 at the University Hospital of Verona (Verona, Italy) were retrospectively reviewed. Visual acuities, surgeries, PCG subtype and etiology of vision impairment were recorded. Statistical analyses were performed to detect factors associated with vision decline. Results Sixty-seven eyes (40 patients) were included in the study. Developmental predictive curves of visual acuity showed that children with infantile PCG had a better visual outcome than children with neonatal PCG at each step of follow-up. A good-to-moderate VA (< 1 LogMAR) was achieved in 56 eyes (83.6%), while 11 eyes (16.4%) had poor VA (≥ 1 LogMAR). The age at onset, sex, number of surgeries, intraocular pressure (IOP) control (with or without antiglaucoma drugs), axial length (AL) and corneal opacities were statistically associated with vision impairment (p < 0.01). The main cause of visual impairment was amblyopia. Conclusions Visual outcomes of PCG significantly correlate with the age at diagnosis. Although a good long-term IOP control can often be achieved in PCG, often the visual acuity remains below the lower limits of the normal range. Poor vision in childhood is related to global developmental problems, and referral to third-level services should not be delayed to prevent vision impairment. In this regard, visual acuity curves can be a useful tool for the consultant ophthalmologist to define the visual development of children affected by PCG.

Abstract
Purpose To report incidence rates of primary congenital glaucoma in Korea and evaluate comorbidity and mortality from 2001 to 2015. Methods This study is a nationwide and retrospective population-based study. We used claims data from the Korean National Health Insurance Service database between 2001 and 2015. Data for all patients diagnosed with primary congenital glaucoma were retrieved using the Korean Electronic Data Interchange and Korean Standard Classification of Diseases-6 codes. Results The number of patients with primary congenital glaucoma between 2001 and 2015 was 776, of which 437 were male (56.31%) and 339 were female (43.69%). The annual prevalence demonstrated a general decreasing trend since 2011, but this was not significant. Over the total survey period, the incidence rate was 11.0 per 100,000 births, with 12.0 cases among males and 10.0 among females. The incidence according to age was 518 (68.78%) patients at age 0, 112 (13.66%) at 1 year, 70 (8.39%) at 2 years, and 76 (9.17%) at 3 years. Of the 776 patients diagnosed with primary congenital glaucoma in the study population, 27 died. The observed mortality per 100,000 people is about 10 times higher than that of the general infant and child population under the age of 4 years. Visual impairment was the most common accompanying disability, followed by brain lesion. Conclusions Our study's estimates of the nationwide population-based incidence of primary congenital glaucoma in a Korean population will expand our understanding of the disease and allow healthcare systems to plan for primary congenital glaucoma.

Abstract
PURPOSE To report the clinical outcomes of glaucoma management in patients with phacomatosis pigmentovascularis (PPV) treated over a period of 3 decades. DESIGN Retrospective cohort study. PARTICIPANTS Fifty-five eyes of 38 patients (21 unilateral and 17 bilateral) with glaucoma in PPV managed at one institution between January 1990 and December 2019 with a minimum follow-up of 1 year. METHODS Medical records of children with glaucoma in PPV were reviewed, and demographic and clinical data were collected. Surgical interventions included primary combined trabeculotomy-trabeculectomy (CTT), trabeculectomy with mitomycin C (MMC), and transscleral cyclophotocoagulation (TSCPC). Complete success was defined as intraocular pressure (IOP) ≥ 6 and ≤ 16 mmHg without medications and qualified success as IOP ≤ 16 mmHg with the use of up to 2 medications. MAIN OUTCOME MEASURES Intraocular pressure, best-corrected visual acuity (BCVA), corneal clarity, antiglaucoma medications at preoperative and postoperative visits (last visit), and complications. RESULTS Median age was 4 months (range, 0.2-252 months) at the time of glaucoma surgery. Thirty-nine eyes (74%) had primary CTT, 10 eyes (19%) had trabeculectomy with MMC, and 4 eyes (7%) with advanced glaucoma had TSCPC. Two eyes (3.6%) received medical treatment. Preoperative IOP reduced from a mean of 25.7 ± 8.4 mmHg on 0.8 ± 0.6 medications to 14.6 ± 5.2 mmHg on 0.4 ± 0.5 medications (P < 0.0001) at last follow-up after surgery (77.7 ± 56.5 months). Thirty-seven eyes (67.3%) required medications preoperatively, and 22 eyes (40%) required medications at the last follow-up. Of 25 patients with available BCVA at last follow-up, 9 (36%) had ≥ 20/60; of these, 6 had > 20/40. Four of 10 eyes that underwent trabeculectomy with MMC developed retinal detachment and were managed surgically; however, all of these eyes had poor visual outcomes. There was no incidence of bleb leakage, bleb-related infection, or endophthalmitis. CONCLUSIONS Combined trabeculotomy-trabeculectomy is safe and effective as a primary procedure for management of glaucoma in PPV. Trabeculectomy augmented with MMC as a second procedure was associated with a higher rate of complications.

Visual outcomes and associated factors of primary congenital glaucoma in children. Graefes Arch Clin Exp Ophthalmol 2021; 259:3445-3451. [PMID: 34076742 DOI: 10.1007/s00417-021-05232-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 04/01/2021] [Accepted: 04/29/2021] [Indexed: 10/21/2022] Open
Abstract
PURPOSE We evaluated the long-term visual outcomes in children with primary congenital glaucoma and determined the factors associated with the final visual outcomes. METHODS Medical records of children with primary congenital glaucoma between 2005 and 2016, seen at Seoul National University Children's Hospital in South Korea, were reviewed. The minimum follow-up period after surgery for primary congenital glaucoma was 3 years. Visual acuity (VA) was categorized into good (≧20/70) and poor (< 20/70). Factors including age, VA, refractive errors, intraocular pressure (IOP), laterality, and cup-to-disc (C/D) ratio were compared between the groups. RESULTS A total of 71 eyes of 44 patients were included. The patients' age at the time of surgery was 14.7 ± 12.2 months. The mean IOP was 28.3 ± 7.0 mmHg. During 6.7 ± 2.7 years of mean follow-up after surgery, 39 eyes (54.9%) needed occlusion treatment. After occlusion, patients with lower IOP values, lesser additional surgeries, reversal of optic disc cupping, and better initially measured VA achieved a better visual outcome. At the final assessment, the mean age was 7.8 ± 2.6 years, and the mean VA gain was 15.0 ± 19.4 letters. There were 44 eyes (62.0%) with VA ≧20/70. CONCLUSIONS In children with primary congenital glaucoma, IOP control and the optic disc configuration over time are important factors associated with visual outcome. Regular follow-up and correction of refractive errors-along with occlusion for those with difference in VA between the two eyes-might be helpful for achieving better visual outcomes.

Risk Factors for Blindness in Children With Primary Congenital Glaucoma-Follow-up of a Registry Cohort. Am J Ophthalmol 2021; 224:238-245. [PMID: 33359680 DOI: 10.1016/j.ajo.2020.12.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 12/08/2020] [Accepted: 12/10/2020] [Indexed: 02/03/2023]
Abstract
PURPOSE To evaluate the baseline features associated with blindness in a cohort of children with primary congenital glaucoma (PCG) from a hospital registry. DESIGN Retrospective clinical cohort study. METHODS Setting: Observational cohort study. StudyPopulation: The registry included all children who presented to our tertiary care institute between 1995 and 2014 with a diagnosis of childhood glaucoma. ObservationProcedure: Baseline characteristics at initial presentation of children with PCG in the registry who were blind at the last follow-up were compared with those who were not blind, using bivariate and then multivariate regressions to account for potential confounders. MainOutcomeMeasures: Blindness was defined as a best-corrected visual acuity of 3/60 (20/400) or worse in the better eye at the final follow-up. RESULTS The eligible sample consisted of 196 children with a mean age of 9.54 ± 22.44 months at presentation. After a mean ± standard deviation follow-up of 8.49 ± 3.85 years, 20 (10.2%) children were blind. The baseline demographic factors, intraocular pressure, horizontal corneal diameter, spherical equivalent, axial length, and corneal thickness, were similar for the "blind" and "not blind" groups (P > .05). In the multivariate regression, only the severity of corneal opacification remained significantly (P < .001) associated with the risk of blindness (odds ratio = 4.05; 95% confidence interval: 1.89-8.85). CONCLUSION Corneal clouding is a predictor of future blindness in children with PCG. Children with severe corneal clouding may need more aggressive intraocular pressure control, closer follow-up, and earlier counseling.

Abstract
PURPOSE To describe neonatal-onset congenital ectropion uveae (N-CEU) as a distinct clinical entity of newborn glaucoma (NG) and to study its significance toward the severity and outcome of NG. DESIGN Prospective clinical cohort study. METHODS The study took place at a tertiary care postgraduate teaching institute. It included consecutive patients with NG who presented between July 1, 2016 and September 30, 2017, with a minimum postoperative follow-up of 1 year. Infants with any ocular anomaly apart from CEU were excluded. Patients with N-CEU were compared with those with neonatal-onset primary congenital glaucoma (N-PCG). All infants underwent goniotomy or trabeculotomy, with trabeculectomy depending on corneal clarity. Clinical features at presentation and outcome 1 year after surgery were defined as good or satisfactory if intraocular pressure was ≤16.0 mm Hg under anesthesia without or with topical medications, respectively, and poor if the infant required additional surgery. RESULTS Twenty eyes of 10 patients with N-CEU were compared with 16 eyes of 9 patients with N-PCG. Infants with N-CEU had significantly worse corneal clarity (mean grade 2.0 ± 0.7 vs 1.4 ± 0.8; P = .026) and poorer outcomes compared with those with N-PCG. Seven of 16 (43.7%) eyes with N-PCG had a cornea clear enough at presentation for a goniotomy compared with only 2 of the 20 (10%) eyes with N-CEU (P = .026). Thirteen of 16 (81.2%) eyes with N-PCG had a good or satisfactory outcome compared with 6 of 20 (30%) eyes with N-CEU (P = .001). CONCLUSIONS N-CEU appears to be distinct from the unilateral CEU in older patients described in the literature and may be considered a poorer prognosis phenotype of neonatal-onset glaucoma.

Abstract
BACKGROUND Neonatal-onset glaucoma (NOG) is a severe form of childhood glaucoma and is not always due to primary congenital glaucoma (PCG). Due to advances in neonatal care, the incidence of NOG is rising, but it remains an under-reported entity. The objective of the paper was to study the clinical profiles, surgical and visual outcomes of NOG at least 1 year following early surgery. METHODS Prospective interventional cohort study at a tertiary care referral centre. Babies with NOG, who presented between January 2013 and December 2017, had a history suggestive of disease onset within 1 month of birth, and underwent surgery by 3 months of age, were prospectively enrolled. Those who completed a 1-year follow-up after surgery were analysed. RESULTS 94 eyes of 53 babies were analysed. 35 (66%) had PCG. Neonatal congenital ectropion uveae, congenital rubella syndrome, Peter's anomaly and Sturge-Weber syndrome comprised the non-PCG group. The mean age at presentation and surgery was 24.8±21.9, and 36.7±29.9 days. Additional glaucoma surgery was required in 43 of the 94 eyes (45.7%). PCG had significantly better outcomes than other glaucomas at all time points. 28.3% of eyes had good vision (LogMar (0-0.5)), 34.7% had moderate visual impairment (LogMar 0.7-1.0) and 16% were blind (LogMar <1.62) . CONCLUSION Our study shows that NOG does not always have a dismal prognosis. A small but significant proportion could have other underlying conditions than PCG. Timely surgery and rigorous amblyopia therapy resulted in good outcomes in terms of intraocular pressure control and vision in this cohort.

Abstract
Glaucoma, being asymptomatic for relatively late stage, is recognized as a worldwide cause of irreversible vision loss. The eye is an impervious organ that exhibits natural anatomical and physiological barriers which renders the design of an efficient ocular delivery system a formidable task and challenge scientists to find alternative formulation approaches. In the field of glaucoma treatment, smart delivery systems for targeting have aroused interest in the topical ocular delivery field owing to its potentiality to oppress many treatment challenges associated with many of glaucoma types. The current momentum of nano-pharmaceuticals, in the development of advanced drug delivery systems, hold promises for much improved therapies for glaucoma to reduce its impact on vision loss. In this review, a brief about glaucoma; its etiology, predisposing factors and different treatment modalities has been reviewed. The diverse ocular drug delivery systems currently available or under investigations have been presented. Additionally, future foreseeing of new drug delivery systems that may represent potential means for more efficient glaucoma management are overviewed. Finally, a gab-analysis for the required investigation to pave the road for commercialization of ocular novel-delivery systems based on the nano-technology are discussed.

Abstract
PURPOSE To determine the prognostic factors for poor visual outcomes in childhood glaucoma. METHODS The medical records of patients with childhood glaucoma diagnosed at age 4 years or younger who were treated surgically from 2002 to 2019 at Songklanagarind Hospital, Hatyai, Thailand, were retrospectively reviewed. Glaucoma subtypes, clinical characteristics, final visual acuity, and etiology of visual impairment were recorded. The generalized estimating equation for logistic regression analysis was used to determine prognostic factors for final visual acuity of worse than 20/200. RESULTS Forty-five eyes of 31 patients were included (33.3% had primary glaucoma and 66.7% had secondary glaucoma). At the final visit (mean: 6.8 years), 20.5% had good visual acuity (20/50 or better), 15.9% had fair visual acuity (worse than 20/50 to 20/200), and 63.6% had poor visual acuity (worse than 20/200). The major cause of visual impairment (worse than 20/50) was deprivation amblyopia. Prognostic factors for poor final visual acuity (worse than 20/200) were secondary glaucoma, age at diagnosis of younger than 3 months, and interval to surgery of more than 3 months. Eyes with a final visual acuity of better than 20/200 had higher mean intraocular pressure preoperatively that tended to increase postoperatively and every visit afterward compared to the other group. CONCLUSIONS Two-thirds of eyes with childhood glaucoma ended up with poor final vision. Early surgery to control intraocular pressure, along with amblyopia treatment, should be considered to prevent poor visual outcome. The prognostic factors for poor visual outcome can contribute to parental advice and planning of patient care. [J Pediatr Ophthalmol Strabismus. 2020;57(5):283-291.].

Long-term morphologic fundus and optic nerve head pattern of progressive myopia in congenital glaucoma distinguished by age at first surgery. Sci Rep 2020; 10:10041. [PMID: 32572115 PMCID: PMC7308308 DOI: 10.1038/s41598-020-67051-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Accepted: 04/09/2020] [Indexed: 11/09/2022] Open
Abstract
The purpose of this study was to investigate the preservation of round optic nerve head (ONH) shape in myopic eyes of surgically treated congenital glaucoma patients, with regard to factors associated with intraocular pressure (IOP) elevation-induced peripapillary scleral (PPS) deformation. Using optical coherence tomography (OCT) on the ONH and macula, we identified myopic eyes with round ONH and internally oblique border tissue and those with non-round ONH. We investigated differences in clinical factors between the two groups. We included 51 eyes of 34 patients. Age at first surgery (2.8 vs. 15.2 months, P < 0.001) was significantly different between the two groups. Axial length was also significantly longer (P = 0.004) in the non-round group, but multiple logistic regression analysis revealed age as the only significant factor (P < 0.05) in ONH roundness. Interestingly, the round ONH group also had non-curved fundus morphology and a thick choroid, while the non-round ONH group showed diverse degrees of disc tilt and posterior pole curvature, and a thin choroid. In conclusion, in eyes with congenital glaucoma, age at first surgery, particularly when older than 6 months, was associated with round ONH and emmetropia-like fundus despite high myopia. The findings may indicate two different changes in the posterior sclera and the neural canal in response to the increased IOP.

Abstract
OBJECTIVE This prospective study aimed to compare the surgical outcomes of ab externo 240-degree trabeculotomy and trabeculotomy-trabeculectomy in managing primary congenital glaucoma (PCG). PATIENTS AND METHODS The study included 30 eyes of 30 patients aged less than 3 years who were diagnosed with PCG and was conducted in Menofia University Hospital between November 2018 and January 2020. The studied eyes were divided into two equal groups. Ab externo 240-degree trabeculotomy and combined trabeculotomy with trabeculectomy with MMC were performed for groups I and II, respectively. Post-operative measurements included intraocular pressure (IOP), optic disc changes, alteration in corneal clarity and transverse corneal diameter, as they are needed for antiglaucoma therapy. Post-operative complications were followed up for 1-year. RESULTS There was significant reduction in IOP in both groups during the follow-up period. The reduction was higher in group I, where mean preoperative IOP was 28.20 ± 1.74 mmHg. The IOP in the group II was 28.07 ± 3.51 mmHg. The mean IOP decreased to 13.93 ± 1.8 mmHg and 14.60 ± 1.24 mmHg in groups I and II, respectively, after 1 year (P < 0.001); however, the difference between the two groups was not significant. Regarding post-operative complications, post-operative hypotony was more common in group I. Other complications such as shallow anterior chamber, choroidal detachment and blebitis occurred more frequently in group II. However, post-operative hyphema was more common in group I. Corneal clarity improved significantly in both groups, but more so in group I, where an improvement was seen in 13 cases (86.6%), compared to 11 cases in group II (73.3%). CONCLUSION Ab externo 240° trabeculotomy and trabeculotomy-trabeculectomy are effective techniques in primary congenital glaucoma with more reduction in IOP in Ab Externo 240° trabeculotomy. Ab externo 240° trabeculotomy provided more better surgical outcome with limited complications, especially those related to bleb formation.

Abstract
Purpose: To study the perceptions, attitude, knowledge of the disease, and impediments to seeking early eye care in caregivers of children with childhood glaucoma. Methods: The study included new and old children diagnosed with childhood glaucoma (which included congenital glaucoma and developmental glaucoma) at a tertiary hospital of east India. The caregivers were administered a video-based questionnaire through open-ended questions intended to collect demographic and other personal details such as caregiver's socioeconomic status, knowledge, attitude towards eye health, and other social barriers. The responses were analyzed using thematic analysis technique into different buckets such as social status, knowledge/attitude, and sociocultural beliefs while individual responses in each bucket were analyzed. Results: Of a total of 43 patients included, >75% of patients came from places >200 km from the eye care centre with >50% coming from >300 km. Most patients presented either <1 year (42%, n = 18) or >3 years (52%, n = 22) with only 2% (n = 3) presenting between 1–3 years of age. The mother was the first person of contact to diagnose the eye abnormality in >45% of patients. Comparing differences among children who presented within 1 year of first diagnosis and those that presented later, caregivers hailing from long-distance >200 km from an eye care center, monthly income <5000 INR, and those with social/cultural taboos (like children's eyes should not be operated) were more likely to seek delayed eye care for congenital glaucoma, P < 0.001. Conclusion: Impediments in seeking early eye care for blinding diseases in children (including distance from the nearest hospital, low socioeconomic constraints, and sociocultural beliefs/taboos) mandate serious policies towards improving education about eye disease and eye health among caregivers.

Abstract
PURPOSE To compare the visual functioning (VF) and vision-related QoL (VRQoL) of children 8-18 years old treated for primary congenital glaucoma (PCG) and secondary childhood glaucoma. DESIGN Cross-sectional study. METHODS A total of 309 children 8-18 years old treated for PCG and secondary childhood glaucoma between 2000 and 2010 by a single pediatric glaucoma specialist were prospectively enrolled at LV Prasad Eye Institute, Hyderabad, India. Children completed 2 questionnaires, the LV Prasad Functional Vision Questionnaire-II (LVP-FVQ-II), and the Impact of Vision Impairment-Children (IVI-C) questionnaire. Rasch-calibrated scores from both these questionnaires were used to compare the VF and VFQoL between the 2 groups. RESULTS Mean ages of the children were 12.2 and 12.6 years in the PCG (53%, median age at diagnosis = 5 months) and secondary glaucoma groups (47%, median age at diagnosis = 3 years), respectively. A majority (80%) of children had bilateral glaucoma and underwent filtering surgery (83%). Mean better eye logMAR visual acuity (VA) was comparable between PCG and secondary childhood glaucoma groups (0.49 vs 0.52, respectively; P = 0.59). Children with PCG reported significantly better VF and VRQoL than secondary childhood glaucoma patients. Unadjusted and adjusted childhood glaucoma group comparisons revealed secondary childhood glaucoma to be associated with worse VF and VRQoL compared to PCG (difference for VF, -0.83; 95% confidence interval [CI], -1.34 to 0.31; P = 0.002; 0.39; 95% CI, 0.16-0.62; P = 0.001 for VRQoL). CONCLUSIONS Results show that children with treated PCG experience significantly better VF and VRQoL than those with secondary childhood glaucoma, despite comparable VA and IOP.

Abstract
PURPOSE To determine the long-term visual outcomes and risk factors for visual loss in children with primary congenital glaucoma (PCG) who underwent angle surgery over a 21-year period. METHODS This was a retrospective study of patients who underwent trabeculotomy, trabeculectomy, or combined trabeculotomy-trabeculectomy for PCG. Visual acuity (VA), surgeries, and underlying cause of visual impairment were recorded and compared. Main outcome measures were final best-corrected good VA (20/20 to 20/50), moderate VA (<20/50 to 20/200), or poor VA (<20/200); age at surgery, sex, laterality, type of initial glaucoma surgery, and number of surgeries were recorded. RESULTS Fifty-three eyes were eligible to be included in the study. The mean logMAR VA was 0.61 ± 0.57. A good VA was attained in 51%, moderate VA in 30%, and poor VA in 19%. The main cause of visual impairment with VA <20/50 was deprivation amblyopia (64%). There was no association between VA level and status of success (controlled with or without medications) (p = 0.202). The mean spherical equivalent of refraction was -4.47 ± 5.66; myopia was the predominant refractive error (74%) and astigmatism >2 D (40%). A statistically significant high myopic shift was more frequent in the visually impaired group. None of the studied factors was statistically associated with moderate to poor visual outcome (all p>0.05). CONCLUSIONS A favorable VA outcome was achieved. Topical antiglaucoma medication has an adjuvant role in maintaining the success rate of surgery without risking the visual outcome. Corneal opacification and anisometropia were the cause of amblyopia.

Abstract
PURPOSE To evaluate the health-related quality of life (HRQoL) of children operated for primary congenital glaucoma (PCG) using the Kidscreen-27 questionnaire. METHODS A total of 121 children (mean age, 11.8 years; SD, 2.8 years; 51% males) with unilateral or bilateral PCG who underwent glaucoma surgery in infancy (mean duration since surgery, 10.2 years; [SD] 4.2 years) by a single surgeon at a tertiary eye care centre were administered the Kidscreen-27 questionnaire (self-or interviewer administered in a face-to-face interview) during their routine follow-up visit. We investigated the measurement properties of Kidscreen-27 questionnaire using Rasch analysis and generated interval-level estimates of HRQoL. The main outcome measure was HRQoL (i.e., Rasch-derived Kidscreen score). Multivariable linear regression analyses assessed the influence of socio-demographic and clinical variables on the HRQoL of children with PCG. RESULTS Majority (83%) of the children had bilateral PCG and congenital type of the disease (79%). Mean presenting acuity (logMAR) in the better eye was 0.32 (SD, 0.36; median, 0.18). Rasch analysis of Kidscreen-27 questionnaire indicated need for minor modifications following which a psychometrically robust unidimensional 23-item Kidscreen questionnaire emerged. In multivariable model, age of the child was independently associated with a 32% (β = -0.24 [95% CI, -0.11, -0.36]) increase in the HRQoL score. CONCLUSIONS Despite undergoing successful glaucoma surgery, children with PCG reported reduced HRQoL. Younger children with PCG are more likely to experience this lowered HRQoL and ophthalmologists will need to be alert to this. Efforts must be made to improve the HRQoL of children with PCG.

OBJECTIVE To evaluate the effect of glaucoma on visual function, as well as quality of life in children and quality of life perceived by caregivers in children up to 16 years of age. MATERIAL AND METHODS An observational and prospective study was designed using the questionnaire GQL-15 (Glaucoma Quality of Life) and conducted on children and caregivers. The questionnaire VFQ-25 (Visual Functioning Questionnaire) was conducted on children. Different variables of the clinical history that could influence the quality of life and visual function were recorded. RESULTS The study included 24 patients with a mean age of 9.13±3.08 years, and included 3 with unilateral involvement, and 20 diagnosed with primary congenital glaucoma. Parents reported a worse quality of life than children. The result of the GQL-15 survey was 32.3±11.56 points in children and 37.52±14.59 points in caregivers (P=.001). The parameter most related to quality of life and visual function was the mean deviation (MD) of the visual field in the best eye. A statistically significant correlation was found between the result of GQL-15 and the mean deviation of the visual field (children: R=0.63, P<.01, caregivers: R=0.81, P<.001). CONCLUSIONS Functional loss has an impact on the quality of life and visual function in children with glaucoma, although the quality of life perceived by the caregivers is worse than that perceived by the child.

Parent-Child Agreement on Health-Related Quality of Life in Congenital Glaucoma. Transl Vis Sci Technol 2018; 7:15. [PMID: 30159208 PMCID: PMC6108530 DOI: 10.1167/tvst.7.4.15] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2018] [Accepted: 07/08/2018] [Indexed: 11/29/2022] Open
Abstract
Purpose We assess parent-child agreement regarding child's health-related quality of life (HRQoL) in children operated for congenital glaucoma (CG). Methods A total of 121 children aged 8 to 18 years (mean age, 11.8 years) operated for CG (mean duration since surgery, 10.2 years) and their parents (mean age, 36.5 years) completed the child and parent versions of the Kidscreen-27 questionnaire, respectively. Psychometric properties of Kidscreen-27 were assessed using Rasch analysis, and child–parent agreement regarding child's HRQoL was investigated using the Bland-Altman limits of agreement (LoA) method. Results Minor modifications in the rating scale and deletion of few misfitting items resulted in a psychometrically robust Kidscreen-23 questionnaire. Average parental HRQoL score was higher than the child's own ratings, with a significant difference between their scores (mean ± standard deviation [SD] difference = 0.53 ± 2.58 logits, P = 0.02; lower LoA [95% CI], −4.52 [−5.31 to −3.72] and upper LoA [95% CI], 5.58 [4.79–6.38]). The range of child–parent agreement was wide and bidirectional, with parents tending to underestimate and overestimate their child's HRQoL. Younger children and girls showed greater discordance in their HRQoL with parental reports than adolescents and boys, respectively. Conclusions Discordance between CG child's self-report of HRQoL and parent's report indicate that both groups perceive the broader impact of living with CG very differently. Translational Relevance The HRQoL as reported by the child with CG and by his/her parent should be viewed as being complementary, rather than interchangeable. Both assessments should be taken into account in clinical practice and research studies.

Abstract
PURPOSE To report our experience on treatment of primary congenital glaucoma with trabeculectomy in combination with biological amniotic membranes soaked with 5-fluorouracil. METHODS This is a retrospective study. Thirty primary congenital glaucoma (PCG) patients (41 eyes) were treated with trabeculectomy in combination with biological amniotic membranes soaked with 5-fluorouracil before operation and followed up for 2.75 ± 1.35 years in average ranging from 1.2 to 5.3 years (Group A). In addition, 22 PCG patients (32 eyes) treated with mitomycin C-trabeculectomy were selected as control and followed up for 2.3 ± 1.25 years in average ranging from 1.4 to 5.1 years (Group B). RESULTS Patients in Group A were 4.74 ± 2.13 years old. After treatment, their mean intraocular pressure decreased from preoperative 38.8 ± 11.3-17.6 ± 8.2 mmHg at 12 months of postoperation (P = 0.0000). At 12 months of follow-up, the intraocular pressure was less than 13 mmHg in 8 eyes (19.5%), between 17 and 13 mmHg in 15 eyes (36.6%), between 21 and 17 mmHg in 12 eyes (29.3%) and more than 21 mmHg in 6 eyes (14.6%). The overall success rate was 85.4%, and total complication rate was 17.1%. By comparison, the overall success rate and total complication rate were 87.5 and 34.4%, respectively, at 12 months of follow-up for patients in Group B. Although the overall success rate was not significantly different between Groups A and B (P = 0.1203) at the end of follow-up, the total complication rate was significantly decreased in Group A (P = 0.0419). CONCLUSION Application of trabeculectomy in combination with biological amniotic membranes soaked with 5-fluorouracil can be an effective surgical treatment method for primary congenital glaucoma patients.

Abstract
Background: Early surgical intervention is required for the primary congenital glaucoma (PCG). There are currently few reports on the surgical outcomes in infants with PCG. This study aimed to evaluate the efficacy and safety of trabeculotomy and the postoperative visual outcomes in Chinese newborns with PCG within 4 weeks of birth. Methods: A total of 21 eyes of 12 patients with PCG who underwent primary trabeculotomy within 4 weeks of birth were retrospectively studied. Preoperative and postoperative intraocular pressure (IOP), corneal clarity and diameter, axial length and optic disc cupping, visual acuity and postoperative refractive error, success rates, and complications were evaluated. Kaplan-Meier survival analysis was applied to evaluate the success rates. Results: The mean follow-up time was 46.9 ± 34.4 months (range: 12–122 months). The postoperative IOP was significantly lower than the preoperative IOP at all of the follow-up visits (P < 0.001). The complete success rates for all eyes at 1, 2, 3, and 5 years postoperatively were 90.5%, 85.7%, 85.7%, and 85.7%, respectively. The IOPs of the three patients who needed antiglaucomatous medications postoperatively were also well controlled. At the last visit, the cornea became clear, and the cup-to-disc ratio decreased significantly (P = 0.01) although the horizontal corneal diameter did not change significantly (P = 0.11). Visual acuities were able to be recorded in eight eyes at the last visit, among which six eyes had a best-corrected visual acuity of 20/40 or better. There were no severe intraoperative or postoperative complications. Conclusions: Trabeculotomy proves to be a safe and effective treatment in reducing IOP in this group of Chinese newborns with PCG. The outcomes of vision function were satisfactory in most of the patients.

Abstract
PURPOSE To compare the outcome of primary trabeculotomy with that of combined trabeculectomy-trabeculotomy (CTT) with mitomycin C (MMC) in children with congenital glaucoma. METHODS This is a prospective comparative study, carried out on a cohort of 28 eyes (28 infants) with congenital glaucoma. Infants with proved congenital glaucoma [based on intra-ocular pressure (IOP), cup/disc (C/D ratio), corneal diameter and axial length measurements] were randomly allocated to either group A (trabeculotomy) or group B (CTT with MMC). Postoperatively, all patients were followed regularly for 3 years; for IOP and C/D evaluation. Criteria for successful outcome included resolution of corneal oedema, reversal of disc cupping, and IOP 18 mmHg or less. RESULTS Success rate in each group was 85.7% (p = 1.00). All preoperative parameters, including horizontal corneal diameter, axial length, IOP and C/D ratio, were not statistically significantly different between the two groups. Also, postoperative C/D ratio, IOP, IOP difference and percentage difference (compared to preoperative values), at different follow-up visits, were not statistically significantly different between both surgical techniques. Comparing preoperative to postoperative IOP and C/D ratio in each group was statistically significant. CONCLUSION Both primary trabeculotomy and CTT with MMC had similar outcomes, which could mean that trabeculotomy could be resorted to first.

Abstract
We provide the diagnosis, treatment and follow-up period of a patient with cloudy cornea in both eyes from birth. A 4-year-old girl presented with blurring in both eyes. Penetrating keratoplasty (PK) was performed with the preliminary diagnosis of congenital hereditary endothelial dystrophy in June 2012. According to the pathology report for extracted host tissue, the Descemet's membrane (DM) and endothelium were healthy and diagnosis was reported to be congenital hereditary stromal dystrophy. Deep anterior lamellar keratoplasty was performed on the left eye. The DM was transparent at follow-up. Cornea transplantation is the only choice to provide visual rehabilitation in children with congenital cloudy cornea. However, it is known that the prognosis of traditional PK in the paediatric age group is not good. Therefore, when using alternative keratoplasty (deep anterior lamellar keratoplasty, Descemet's stripping automated endothelial keratoplasty) options, pathological examination of the host tissue should be made.

Abstract
PurposeTo determine the long-term surgical and visual outcomes in Indian children with early-onset glaucoma associated with Axenfeld-Rieger anomaly (ARA).MethodsThis is a retrospective analysis of 44 eyes of 24 consecutive children with early-onset glaucoma (within 3 years of age) and ARA who underwent glaucoma surgery over a 20-year period (1991-2010) by a single surgeon. Main outcome measures were pre- and postoperative intraocular pressures (IOPs), corneal clarity, visual acuities (VAs), refractive errors, success rate, time of surgical failure, and complications.ResultsThe series consisted of 38 primary combined trabeculotomy-trabeculectomy (CTT) and 6 primary trabeculectomy procedures (Schlemm's canal could not be identified in these eyes). There was a statistically significant reduction in IOP postoperatively (27.07±4.88 vs 14.88±3.62 mm Hg; P<0.0001) with a mean reduction of 45.14%. Success probability by Kaplan-Meier survival analysis was 93% till 5 years, and then 88.1%, 82.3%, 70.5%, 56.4%, and 42.3% at year 6, 7, 8, 9, and 10, respectively. Preoperative corneal edema was present in 43/44 eyes (97.72%) and cleared in 42 eyes (97.67%). There was one case each with intraoperative hyphema and with shallow chamber postoperatively and both were successfully managed successfully. There was no incidence of endophthalmitis or any other sight-threatening complication. Data on VA were available in 34 eyes (77.3%). At final follow-up visit, 15 (44.1%) eyes had best corrected VA ⩾6/18.ConclusionsPrimary CTT is safe and effective for early-onset glaucoma associated with ARA. It leads to excellent IOP control and satisfactory visual outcome.

Abstract
PURPOSE To describe demographic criteria of primary congenital glaucoma (PCG) subjects and to evaluate the surgical outcomes of children who underwent angle surgery over a 20-year period. METHODS This is a retrospective study of patients diagnosed with PCG who underwent trabeculotomy, trabeculectomy, or combined trabeculotomy-trabeculectomy (CTT). The surgery was considered to be successful if intraocular pressure (IOP) was 21 mm Hg or less with or without treatment. RESULTS A total of 148 eyes (85 patients) were included in the study. The majority of the patients were younger than 6 months of age (78.9%), with a median age of 2 months. Sex distribution was relatively even between girls and boys (45:40) (53%/47%). Bilateral disease was seen in 63 patients (74%). The overall success rate was achieved in 80.4%. The majority of the eyes needed only one surgery (105 [70.9%]), 34 eyes (23.0%) needed 2 surgeries, and 7 eyes (4.7%) had 3 surgeries. There was no statistically significant difference in success rate between types of surgery and number of performed procedures. A progressive decline in success rate over time was evident, as success rate dropped from 96.6% at 5 months to less than 50% after 11 years of follow-up. CONCLUSIONS Excellent IOP control can be achieved in a majority of patients with equally effective results from all 3 surgical procedures. The surgical outcome of PCG was more favorable in infants presenting before the age of 6 months. Adjuvant topical antiglaucoma medications can augment the surgical success rate.

Abstract
PURPOSE This case report describes the surgical technique of trabeculectomy, mechanical separation of the iris from the cornea, and creation of a pupillary aperture by an automated vitrector in a child with newborn glaucoma with imperforate pupil. CASE REPORT A 1-month-old child was referred to us with the diagnosis of congenital glaucoma of the left eye. Examination under anesthesia revealed megalocornea (corneal diameter, 12 mm) with corneal edema of the left eye whereas the right eye was normal. Intraocular pressure was 8 and 26 mm Hg in the right eye and left eye, respectively. Examination under anesthesia revealed imperforate pupil with uveal tissue attached on the back surface of the left cornea whereas the iris and the pupil of the right eye were normal. A diagnosis of newborn glaucoma and imperforate pupil of the left eye was made and the child underwent trabeculectomy, mechanical separation of the iris from the back surface of the cornea, and creation of pupillary aperture by an automated vitrector. The child had an uneventful postoperative course with disappearance of corneal edema, but there were several linear scars across the cornea. The child completed 3 years of follow-up and his best spectacle corrected visual acuity in the left eye was 20/32 and the intraocular pressure was 10 mm Hg in both eyes. CONCLUSIONS The surgical technique was safe and effective in the restoration of corneal clarity and creation of the pupillary aperture with good visual recovery.

Abstract
PURPOSE The aim was to report the outcome of Ahmed glaucoma valve (AGV) (New World Medical, Inc., Rancho Cucamonga, CA, USA) implantation as a surgical intervention following an initial failed combined trabeculotomy + trabeculectomy (trab + trab) in refractory primary congenital glaucoma (RPCG). MATERIALS AND METHODS Retrospective chart review of 11 eyes of 8 patients who underwent implantation of AGV (model FP8) for RPCG between 2009 and 2011. Prior trab + trab had failed in all the eyes. Success was defined as an intraocular pressure (IOP) >5 and ≤ 18 mmHg during examination under anesthesia with or without medications and without serious complications or additional glaucoma surgery. RESULTS The mean age at AGV implantation was 15.4 ± 4.9 months. The mean preoperative IOP was 28 ± 5.7 mmHg which reduced to 13.6 ± 3.4 mmHg postoperatively at the last follow-up (P < 0.0001). The number of topical antiglaucoma medications reduced from a mean of 2.6 ± 0.5 to 1.6 ± 0.9 postoperatively (P = 0.009). The definition of qualified success was met in 10 (90%) eyes. One eye developed a shallow anterior chamber with choroidal detachment at 1-week, which resolved spontaneously with medications. None of the eyes developed a hypertensive phase. One eye had a long tube resulting in tube corneal touch that required trimming of the tube. One eye developed tube retraction, which was treated with a tube extender. The mean follow-up was 17.9 ± 9.3 (6.2-35.4) months. CONCLUSION Managing RPCG remains a challenge. AGV implant was successful in a significant proportion of cases.

Abstract
PURPOSE To determine in primary congenital glaucoma whether age of presentation influences surgical success, the degrees of angle surgery needed to achieve glaucoma control, and whether there are critical ages where glaucoma progresses, requiring further surgical management. DESIGN Retrospective cohort study. METHODS The medical records of patients with primary congenital glaucoma over a 23-year period were reviewed: 192 procedures were performed on 117 eyes (70 patients). The number and age of angle procedures and final visual acuity was analyzed. Surgical success was defined as stable intraocular pressure and optic disc appearance. RESULTS Procedures involving 83 of the 110 eyes (75.5%) undergoing angle surgery were successful, with 2-, 4-, 6-, and 10-year success rates of 92%, 86%, 84%, and 75%, respectively. Subgroup analysis (<3 months; 3-6 months; >6 months) comparing age of diagnosis to visual outcome (<20/200, 20/200-20/40, >20/40) was significant (P = .04). The age at first operation (P = .94), the number of angle operations (P = .43), and their effect on angle surgery success was not significant. Seven of 192 operations were performed after the age of 8 years (3.6%). After the initial angle surgeries within the first year of life, the third procedure occurred at a median age of 2.4 years (interquartile ratio [IQR] 0.6-3.8 years) and the fourth procedure occurred at a median age of 5.3 years (IQR 2.5-6.1 years). CONCLUSIONS Children diagnosed at <3 months of age had a visual outcome of <20/200 despite successful glaucoma control. Age of presentation did not affect surgical success. A total of 78.9% of cases undergoing primary trabeculotomy were controlled with 1 operation: 4 clock hours of angle (120 degrees). Analysis of glaucoma progression suggests critical ages where further glaucoma surgery is required at around 2 and 5 years of age.

Abstract
PURPOSE To evaluate the outcome of Ahmed glaucoma valve (AGV) implantation in primary congenital glaucoma (PCG). METHODS The medical records of patients with PCG refractory to trabeculotomy and medical therapy who had undergone AGV implantation with a minimum follow-up of 6 months were retrospectively reviewed. The primary outcome measure was cumulative probability of success, defined as intraocular pressure (IOP) of 6-21 mm Hg, with or without medication, and no serious complications, additional glaucoma surgery, or loss of light perception. RESULTS A total of 33 eyes of 22 children with a mean age (and standard deviation) of 2.7 ± 3.1 years were included. The patients had a mean follow-up time of 32.6 ± 18.3 months. The mean IOP was 32.8 ± 7.3 mm Hg preoperatively and 16.8 ± 4.0 mm Hg postoperatively. The number of glaucoma medications was 2.5 ± 0.7 preoperatively and 2.2 ± 0.7 postoperatively. The cumulative probability of success (and standard error) was 97% ± 3.0% in the 1st year, 85% ± 7.0% in the 2nd year, and 56% ± 14.8% in the 5th year. When only the first operated eye per patient was included, the cumulative probability of success was 96% ± 4.4% in the 1st and the 2nd years and 72% ± 15.3% in the 5th year. Major complications comprised tube-endothelial touch (3 eyes), cataract (2 eyes), shunt extrusion (1 eye), and retinal detachment (1 eye). CONCLUSIONS AGV implantation in patients with PCG offers moderate success in controlling the IOP with a low rate of complications. Most continued to require medications.

Abstract
Primary congenital glaucoma (PCG) is a childhood irreversible blinding disorder with onset at birth or in the first year of life. It is characterized by the classical traid of symptoms viz. epiphora (excessive tearing), photophobia (hypersensitivity to light) and blepharospasm (inflammation of eyelids). The only anatomical defect seen in PCG is trabecular meshwork dysgenesis. PCG shows autosomal recessive mode of inheritance with considerable number of sporadic cases. The etiology of this disease has not been fully understood but some genes like CYP1B1, MYOC, FOXC1, LTBP2 have been implicated. Various chromosomal aberrations and mutations in mitochondrial genome have also been reported. Molecular biology has developed novel techniques in order to do genetic and biochemical characterization of many genetic disorders including PCG. Techniques like polymerase chain reaction, single strand conformational polymorphism and sequencing are already in use for diagnosis of PCG and other techniques like protein truncation testing and functional genomics are beginning to find their way into molecular workout of this disorder. In the light of its genetic etiology, it is important to develop methods for genetic counseling for the patients and their families so as to bring down its incidence. In this review, we ought to develop a genetic insight into PCG with possible use of molecular biology and functional genomics in understanding the disease etiology, pathogenesis, pathology and mechanism of inheritance. We will also discuss the possibilities and use of genetic counseling in this disease. How to cite this article: Faiq M, Mohanty K, Dada R, Dada T.

Abstract
Background To report a case with hypotony due to late leakage of the filtering bleb performed during childhood and treated surgically using human pericardium graft. Case Presentation A man with hypotony related to bleb's leakage in his right eye was presented. During his childhood trabeculectomy was performed to manage ocular hypertension due to pediatric glaucoma. Biomicroscopy revealed choroidal tissue incarcerated in the sclerectomy under the conjunctiva. Bleb revision was performed. Human pericardium graft was used to cover the sclerectomy and a new bleb with controlled outflow was created. The intraocular pressure (IOP) and Seidel test represent the main outcomes. Intraoperative and postoperative complications were recorded. Fifteen days postoperatively the IOP was of 7 mmHg and the bleb seemed to filter properly. Five months later the IOP was 9 mmHg and no complications were noticed. During the follow up time, the Seidel test was negative. Conclusion We used human pericardium graft with no complications in a case of bleb leakage performed for pediatric glaucoma.

Abstract
PURPOSE To evaluate the long-term outcome of primary congenital glaucoma in patients followed for more than 20 years. METHODS All patients with a diagnosis of congenital glaucoma who were examined in the pediatric glaucoma clinic at Moorfields Eye Hospital from 2005 to 2006 were included. The follow-up period was a minimum of 20 years; patients with pediatric glaucoma secondary to other etiologies were excluded. Data collected included visual acuity, optic disk cupping, intraocular pressure (IOP), corneal diameter, pachymetry, visual fields, refraction, strabismus, glaucoma management, and ocular comorbidity. Progressive congenital glaucoma, defined as an increase of the cup/disk ratio of >0.2 secondary to elevated IOP, was evaluated with the use of Kaplan-Meier survival curves. Patients were divided into 1 of 3 groups: (1) stable glaucoma with no visual impairment; (2) glaucoma progression with sight-threatening consequences; and (3) poor visual acuity as a result of ocular comorbidity. RESULTS A total of 30 eyes of 16 patients were identified. Mean follow-up was 34 ± 10 years (range, 22-59 years). At the final clinical assessment, mean IOP was 13.6 ± 4.3 mm Hg and mean cup/disk ratio was 0.7 ± 0.3 (p < 0.05). Survival analysis demonstrated lack of progression in 90.3% at 1 year, 83.1% at 5 years, 70.8% at 10 years, 58.3% at 34 years, and 48.6% at 40 years. CONCLUSIONS Apparently stable congenital glaucoma may progress with sight-threatening complications after many years of IOP stability. Monitoring of these patients is indicated throughout life.

Abstract
PURPOSE To evaluate the surgical outcome of combined trabeculotomy-trabeculectomy in Ghanaian children with primary congenital glaucoma. MATERIALS AND METHODS A retrospective case series involving 19 eyes of 12 consecutive children with primary congenital glaucoma who had primary trabeculotomy-trabeculectomy from 12 August 2004 to 30 June 2008, at the Korle-Bu Teaching Hospital, Ghana. Main outcome measures were preoperative and postoperative intraocular pressures, corneal diameter, corneal clarity, bleb characteristics, duration of follow-up, surgical success, and complications. RESULTS A total of 19 eyes of 12 patients met the inclusion criteria. Six of the patients were males. Mean age at diagnosis was 4.4 (range 2-8) months. Mean age at surgery was 5.9 months (range 3-16). Eight (67%) infants had bilateral disease. Mean duration of follow-up was 13.1 (range 5-38) months. The preoperative mean horizontal corneal diameter was 13.4 ± 1.1(range 12-16) mm. Complete success (intraocular pressure <21 mm Hg) was obtained in 15 (79%) eyes. The probability of success was 94.4, 83.3, 66.7, 44.4, 38.9, 33.3, and 13.3% at 3, 6, 9, 12, 15, 18, and 21 months, respectively (Kaplan-Meier analysis). All eyes had corneal oedema preoperatively. Seventeen eyes (90%) had clear cornea at their last follow-up. Mean preoperative and postoperative intraocular pressures were 30.3 ± 8.8 and 18.1 ± 6.8 mm Hg respectively (P<0.001, t-test). Twelve (63%) eyes had well-functioning blebs at the last follow-up. One eye (5%) developed seclusio pupillae and cataract postoperatively. CONCLUSION The overall success for combined trabeculotomy-trabeculectomy in Ghanaian children with primary congenital glaucoma was 79%. The probability of success reduced from more than 66% in the first 9 months postoperatively to below 45% after that.
