Abstract
BACKGROUND Complete cryptophthalmos, congenital aphakia, and corneal vascularization are relatively uncommon congenital eye malformations during the fetal period. Herein, we report a case of a fetus with complete cryptophthalmos, congenital aphakia, and corneal vascularization in both eyes and review previous prenatal reports of related cases. CASE PRESENTATION The patient was a 27-year-old pregnant woman, gravida 2, para 1, who was referred to our hospital for consultation at 23 weeks of gestation due to a diagnosis of fetal right renal agenesis at an external hospital. The ultrasound system of our hospital diagnosed the fetus with complete cryptophthalmos, congenital aphakia, and corneal vascularization, which was verified under the postnatal water basin test, anatomical and pathological sections. CONCLUSIONS Fetal ocular malformations are often associated with malformations of other organs, and if ultrasound findings are associated with such malformations, attention should be paid to the ocular examination to avoid missing the diagnosis.

Abstract
PURPOSE To compare the preoperative central corneal thickness (CCT) in eyes with unilateral cataract with their normal fellow eyes in the pediatric population. METHODS A retrospective chart review was conducted using the STORM Kids cataract database. Eyes with traumatic cataract, previous surgery or therapeutic manipulation, or age >18 years were excluded. Only eyes with a normal fellow eye were included. The intraocular pressure, age at time of surgery, race, sex, and type of cataract were also extracted from the record. RESULTS A total of 70 eyes with unilateral cataract and 70 fellow normal eyes met inclusion criteria. The mean age at the time of surgery was 3.35 years (range, 0.08-15.05). The mean preoperative CCT in the operated eyes was 577 ± 58 μm (range, 464-898 μm). The mean preoperative CCT in fellow eyes was 570 ± 35 μm (range, 485-643 μm). There was no statistically significant difference between the preoperative CCT in cataract eyes versus unaffected fellow eyes (P = 0.183). When stratified by age, the difference in the CCT between cataract and fellow eyes was greatest in the <1 year age group, but was not statistically significant (P = 0.236). The mean preoperative corneal diameter of operative eyes was 11.0 mm (range, 5.5-12.5 mm [n = 68]). The mean preoperative IOP was 15.1 mm Hg (n = 66). CONCLUSIONS In our study cohort, there was no significant difference in mean preoperative CCT between unilateral pediatric cataract eyes and unaffected fellow eyes.

Abstract
PRéCIS:: The overall incidence of postoperative suspected glaucoma and glaucoma after congenital cataract surgery is low; however, the identification of the associated risk factors helps to monitor susceptible individuals and to provide real-time surveillance and timely intervention. PURPOSE Pediatric patients who have undergone surgery for congenital or infantile cataracts have a risk of developing suspected glaucoma and glaucoma, but the current evidence does not address our understanding of the incidence and associated risk factors of suspected glaucoma/glaucoma for application in clinical standard care. Therefore, this study investigated the incidence of and risk factors for suspected glaucoma/glaucoma in patients who have undergone surgery for congenital/infantile cataracts. METHODS This study used a prospective cohort of 241 eyes from 241 patients who were 10 years of age or younger and who had undergone congenital/infantile cataract surgeries and were recruited from January 2011 to December 2016 at the Zhongshan Ophthalmic Center. Pediatric patients who underwent cataract surgery were classified into 2 groups according to intraocular lens (IOL) implantation. The patients' baseline characteristics and the incidence and risk factors for suspected glaucoma/glaucoma were assessed. RESULTS The incidence of suspected glaucoma after cataract surgery was 10.70% [26 of 241 eyes; 95% confidence interval (CI), 6.88%-14.70%]. The rate of suspected glaucoma developing into glaucoma was 26.92% (7 of 26 eyes; 95% CI, 9.87%-43.97%), and the incidence of glaucoma was 2.90% (7 of 241 eyes; 95% CI, 0.79%-5.03%). Our study revealed that the incidence of suspected glaucoma/glaucoma in patients who did not receive IOL implantation was 13.91% (21 of 151 eyes; 95% CI, 8.39%-19.42%), and the incidence in patients who received IOL implantation was 5.56% (5 of 90 eyes; 95% CI, 8.23%-10.28%). The preoperative central corneal thickness (hazard ratio, 1.003; 95% CI, 1.001 to 1.004; P=0.004) and a family history of congenital cataracts (hazard ratio, 2.314; 95% CI, 1.004-5.331; P=0.049) were significant risk factors in patients without IOL implantation. Patient age at the time of cataract surgery was not a statistically significant risk factor for the development of suspected glaucoma/glaucoma in patients without IOL implantation. CONCLUSIONS Identification of the incidence of and risk factors for suspected glaucoma/glaucoma may help clinicians monitor susceptible individuals and provide timely surveillance and interventions in a clinical setting. Age at the time of cataract surgery was not a risk factor for suspected glaucoma/glaucoma in patients without IOL implantation, and this may allow the timing window for pediatric cataract surgery to be expanded and support new insights into the optimal timing of surgery for standard care.

Abstract
PURPOSE To compare intraocular pressure measured using the Goldmann applanation tonometer with that measured using the ocular response analyzer after congenital cataract surgery. METHODS This study included 113 eyes of 64 patients who underwent lensectomy and vitrectomy. In all, 36 eyes remained aphakic after surgery. Intraocular lens implantation was performed at the time of surgery in 47 eyes and secondarily in 30 eyes. Corneal hysteresis, corneal resistance factor, and cornea-compensated intraocular pressure were measured. The influences of independent factors on the difference between the cornea-compensated intraocular pressure and intraocular pressure measured with Goldmann applanation tonometer were investigated using linear regression analyses. Agreement between the two tonometers was investigated using the Bland and Altman and 95% limits of agreement analysis. RESULTS Central corneal thickness, corneal hysteresis, and corneal resistance factor were 591.2 ± 53.3 µm, 10.83 ± 2.27 mmHg, and 11.36 ± 2.14 mmHg, respectively. Cornea-compensated intraocular pressure (16.75 ± 4.82 mmHg) was significantly higher than intraocular pressure measured with Goldmann applanation tonometer (14.41 ± 2.27 mmHg, p < 0.001). Central corneal thickness (p = 0.02) and corneal hysteresis (p < 0.001) were identified as the main predictors of difference between cornea-compensated intraocular pressure and intraocular pressure measured with Goldmann applanation tonometer readings. A 95% limits of agreement for cornea-compensated intraocular pressure and intraocular pressure measured with Goldmann applanation tonometer was between -4.86 and 9.53 mmHg in the entire group. Cornea-compensated intraocular pressure showed the best agreement with intraocular pressure measured with Goldmann applanation tonometer in the primary pseudophakic subgroup as compared to the other subgroups. CONCLUSION The Goldmann applanation tonometer and ocular response analyzer cannot be used interchangeably for measuring intraocular pressure after congenital cataract surgery. The difference between the cornea-compensated intraocular pressure and intraocular pressure measured with Goldmann applanation tonometer was primarily affected by central corneal thickness and corneal hysteresis. Among the subgroups, the primary pseudophakic subgroup had the thinnest cornea and the highest corneal hysteresis values and demonstrated the best agreement between the two tonometers.

Abstract
PURPOSE To report the long-term risk of glaucoma development in children following congenital cataract surgery. DESIGN Retrospective interventional consecutive case series. METHODS We retrospectively reviewed the records of 62 eyes of 37 children who underwent congenital cataract surgery when <7 months of age by the same surgeon using a limbal approach. The Kaplan-Meier method was used to calculate the probability of an eye's developing glaucoma and/or becoming a glaucoma suspect over time. RESULTS The median age of surgery was 2.0 months and the median follow-up after cataract surgery was 7.9 years (range, 3.2-23.5 years). Nine eyes (14.5%) developed glaucoma a median of 4.3 months after cataract surgery and an additional 16 eyes (25.8%) were diagnosed as glaucoma suspects a median of 8.0 years after cataract surgery. The probability of an eye's developing glaucoma was estimated to be 19.5% (95% CI: 10.0%-36.1%) by 10 years after congenital cataract surgery. When the probability of glaucoma and glaucoma suspect were combined, the risk increased to 63.0% (95% CI: 43.6%-82.3%). CONCLUSIONS Long-term monitoring of eyes after congenital cataract surgery is important because we estimate that nearly two thirds of these eyes will develop glaucoma or become glaucoma suspects by 10 years after cataract surgery.

Abstract
PURPOSE To study effects of Artisan iris fixated intraocular lens (IOL) on central corneal thickness (CCT) and intraocular pressure (IOP) in pediatric eyes with crystalline subluxated lenses. MATERIALS AND METHODS The study included 17 eyes undergoing Artisan aphakic IOL implantation after lensectomy for subluxated crystalline lenses. CCT and IOP measurements were recorded pre-operatively and post-operatively taking the mean of 4 post-operative visits. Patients were divided into Group A (n = 8) including patients with lensectomy and iris fixation of Artisan IOL as a primary procedure and Group B (n = 9) including patients in which lensectomy was carried out as a primary surgery and Artisan IOL fixation as a secondary procedure. RESULTS Children ranged in age from 08 years to 16 years, mean 11.59 ± 2.96 years. Follow-up period ranged from 7 months to 16 months, mean 11.24 months ± 4.27. Mean pre-operative and post-operative IOP in Group A was 14.88 ± 2.80 and 14.16 ± 0.59 respectively (P = 0.528). In Group B it was 12.44 ± 2.79 and 14.44 ± 1.15 respectively (P = 0.080). Mean pre-operative and post-operative CCT in Group A was 529.13 ± 24.23 and 529.87 ± 17.46 respectively (P = 0.674). In Group B it was 567.33 ± 29.13 and 568.83 ± 25.69 respectively (P = 0.859). CONCLUSIONS Primary and secondary Artisan aphakic IOL implantation did not cause any significant changes in corneal thickness or IOP during the follow-up period.

Abstract
BACKGROUND Central corneal thickness (CCT) is an important measurement in the treatment and management of pediatric glaucoma and potentially of refractive error, but data regarding reliability of CCT measurement in children are limited. The purpose of this study was to evaluate the reliability of CCT measurement with the use of handheld contact pachymetry in children. METHODS We conducted a multicenter intraobserver test-retest reliability study of more than 3,400 healthy eyes in children aged from newborn to 17 years by using a handheld contact pachymeter (Pachmate DGH55; DGH Technology Inc, Exton, PA) in 2 clinical settings--with the use of topical anesthesia in the office and with the patient under general anesthesia in a surgical facility. RESULTS The overall standard error of measurement, including only measurements with standard deviation ≤5 μm, was 8 μm; the corresponding coefficient of repeatability, or limits within which 95% of test-retest differences fell, was ±22.3 μm. However, standard error of measurement increased as CCT increased, from 6.8 μm for CCT less than 525 μm, to 12.9 μm for CCT 625 μm and greater. The standard error of measurement including measurements with standard deviation >5 μm was 10.5 μm. Age, sex, race/ethnicity group, and examination setting did not influence the magnitude of test-retest differences. CONCLUSIONS CCT measurement reliability in children via the Pachmate DGH55 handheld contact pachymeter is similar to that reported for adults. Because thicker CCT measurements are less reliable than thinner measurements, a second measure may be helpful when the first exceeds 575 μm. Reliability is also improved by disregarding measurements with instrument-reported standard deviations >5 μm.

Abstract
BACKGROUND To evaluate long-term changes in corneal endothelial cell count and morphology after congenital cataract extraction and intraocular lens implantation. METHODS Cataract extraction and posterior chamber intraocular lens (IOL) implantation was performed on 54 congenital cataract patients (83 eyes). The corneal endothelial cell density (ECD), coefficient of variation (CV), hexagonality, and central corneal thickness (CCT) were measured for a retrospective analysis of long-term changes in corneal endothelial characteristics. RESULTS The mean age at the time of IOL implantation was 5.00 (3.62) years [mean (SD)], and the mean follow-up period was 8.83 (1.49) years. In a comparison of the treated and normal eyes of patients who underwent unilateral surgery, the treated eyes showed a significantly greater CCT (p < 0.05), and there was no significant difference in ECD, CV, and hexagonality (p > 0.05). In addition, there was no statistically significant difference in the ECD and CCT between the primary and secondary IOL implantation groups. CONCLUSIONS Our results did not show any significant corneal endothelial cell loss in congenital cataract patients; however, their CCTs were increased.

Abstract
PURPOSE To evaluate central corneal thickness (CCT) in children with congenital/developmental cataracts before and after cataract removal, to correlate CCT with corneal diameters before cataract surgery in this same group, and to evaluate CCT over time in a separate group of children who were already aphakic or pseudophakic at study entry. DESIGN Longitudinal study. METHODS Children with cataract (Group 1, with pre-cataract-removal CCT) and aphakia/pseudophakia (Group 2, presenting after cataract removal) were included. CCT measurements were performed using ultrasound pachymetry. Normal fellow eyes of unilaterally affected cases served as controls. In bilateral cases, right eyes were used for analyses. RESULTS Group 1 comprised 66 children. Before cataract surgery, unilateral cases (n = 31) showed similar CCT and strong association between the affected and fellow eyes (552.0 ± 32.9 μm vs 550.9 ± 40.4 μm, respectively; r(2) = 0.71, P = .0001). After cataract surgery, affected eyes (n = 13) showed mean CCT increase of 29.7 ± 43.1 μm (P = .03) while fellow eyes remained unchanged. Similarly, before cataract surgery, bilateral cases (n = 35) showed similar CCT between the right and left eyes. After cataract surgery, mean CCT increase was 27.4 ± 39.4 μm for first operated eyes of bilateral cases (n = 17, P = .01). Group 2 comprised 50 aphakic/pseudophakic children lacking pre-cataract-removal CCT. CCT was higher in eyes with glaucoma vs those without, at both first and last measurements (ΔCCT 58.9 ± 27.0 μm at first examination, P = .034, and 56.4 ± 27.1 μm at last examination, P = .043, respectively). There was no statistically significant CCT change over the study interval (median 28 months) for either Group 2 eyes with or those without glaucoma. CONCLUSIONS CCT in children with cataracts increases after cataract surgery while the fellow eye remains stable. This increase seems to occur early after surgery, likely remaining stable thereafter, though glaucoma can accentuate the increase.

Abstract
AIM To observe the central corneal thickness (CCT) changes in infants and young children who had been undergone bilateral congenital cataract surgery, and to compare the changes with normal control group which was selected from healthy population. METHODS A cross section case-control study contained 28 cases (56 eyes) of bilateral aphakia (aphakic group) due to congenital cataract surgery combining with posterior continuous curvilinear capsulorhexis and with anterior vitrectomy during 2-6 months after birth. Fourteen children (28 eyes) of age-sex matched with the aphalic group were selected as normal control group. CCT and intraocular pressure (IOP) were measured postoperatively and the results were compared between groups. RESULTS The mean CCT was 653.5±82.4μm in the aphakic group and 579.6±39.2μm in the control group, with a significant difference (P=0.000). The mean value of IOP in aphakic group (22.0±1.6mmHg) was greater than that of control group (16.9±2.1mmHg), P=0.023. There was a negative correlation between age and CCT in normal control group (r=-0.531, P=0.026), and there was no correlation in bilateral aphakia group (r=-0.324, P=0.165) CONCLUSION Aphakic children due to congenital cataract surgery have a greater CCT than normal children. It is necessary to consider CCT in evaluating IOP for children after congenital cataract surgery.

Abstract
Purpose TO determine the central corneal thickness (CCT) in microphthalmic aphakic or Pseudophakic eyes as well as in microphthalmic eyes without any history of eye surgery. Methods Thirty-two patients with a mean age of 6.41 ±5.24 years after congenital cataract surgery with absolute microcornea, i.e., horizontal corneal diameter (HCD) <10 mm, or relative microcornea, i.e., HCD 10–11 mm but in the affected eye at least 0.5 mm smaller compared to the fellow eye, formed group A. Thirteen patients of mean age 0.94±1.22 years with absolute or relative microcornea plus another developmental anomaly of an eye without any history of eye surgery formed group B. The patients with corneal edema or scars were excluded. The control group consisted of 124 healthy school-aged children. Horizontal corneal diameter was measured with caliper and CCT with an ultrasound pachymeter. In infants, these measurements were performed under general anesthesia. Results In 48 eyes in group A and in 16 eyes in group B, the mean CCT was 635.13±65.35 μm and 642.31±93.07 μm, respectively, which was significantly greater (p<0.0001 and p=0.0018) in comparison with the mean CCT (553.58±33.12 μm) in the control group. Regression curve demonstrated the significant increase of CCT values along with the decrease of HCD in microphthalmic eyes. Conclusions Small corneas in microphthalmic eyes either with or without congenital cataract surgery have significantly higher CCT. The results demonstrate significant negative correlation between horizontal corneal diameter and CCT.
