UGH Syndrome Resolution after IOL Explantation and Concomitant Carlevale IOL Implantation. Ocul Immunol Inflamm 2024; 32:320-325. [PMID: 36749924 DOI: 10.1080/09273948.2023.2169716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 01/02/2023] [Accepted: 01/12/2023] [Indexed: 02/09/2023]
Abstract
OBJECTIVE To examine the use of Carlevale IOL placement in patients with UGH, and to evaluate surgical outcomes. DESIGN In this retrospective study, 28 patients with UGH syndrome that were subjected to IOL explantation and concomitant Carlevale IOL implantation were included in the study. METHODS Information about VA, IOP, number of glaucoma medication, need for glaucoma surgery, presence of hemorrhage and inflammation were recorded up to 6 months after the procedure. RESULTS We found a statistically significant increase in mean visual acuity and complete resolution of uveitis in all patients. Mean IOP and the mean number of glaucoma medications were significantly decreased postoperatively, while 14% of patients required additional glaucoma surgery. CONCLUSIONS IOL explantation and concomitant Carlevale IOL implantation may provide a viable solution for UGH syndrome resolution, increases visual acuity, and decreases the need for glaucoma medication.

Uveitic Flare-Ups After Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) in Patients with Uveitic Glaucoma. Ocul Immunol Inflamm 2024:1-7. [PMID: 38470999 DOI: 10.1080/09273948.2024.2316760] [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: 06/21/2023] [Accepted: 02/05/2024] [Indexed: 03/14/2024]
Abstract
PURPOSE To assess the risk of gonioscopy-assisted transluminal trabeculotomy (GATT) inducing an uveitic flare-up in patients with uveitic glaucoma (UG). METHODS This retrospective study included consecutive UG patients who underwent GATT at a single medical center between June 2020 and September 2022. The main outcome measure was the occurrence of a surgery-related uveitic complication defined as either an uveitic flare-up defined by the Standardization of Uveitis Nomenclature (SUN) criteria, or the appearance of cystoid macular edema (CME) from 2 weeks to 3 months after surgery. RESULTS A total of 25 eyes of 22 patients were included in the study. Age ranged from 10-78 and 64% were women. The most common uveitic etiologies were juvenile idiopathic arthritis (JIA, 24%) and herpetic infection (24%). A total of 48%of the patients were on systemic immunosuppressants prior and unrelated to surgery. Eight eyes (32%) had severe glaucomatous damage prior to surgery, and 20% of the patients had undergone previous glaucoma surgery. Two cases (8%) demonstrated uveitic flare-up in the early postoperative period: a case of mild anterior chamber reaction and a case of CME with persistent edema prior to surgery. Average intraocular pressure (IOP) was reduced from 26.7 mm Hg on four medications to 12.2 on 1.1 after 1 year. One patient required reoperation for IOP control. CONCLUSIONS With careful pre and postoperative care, GATT seems to be a low-risk procedure for uveitic flare-ups in patients with UG.

Update on Diagnosis and Treatment of Uveitic Glaucoma. J Clin Med 2024; 13:1185. [PMID: 38592059 PMCID: PMC10931771 DOI: 10.3390/jcm13051185] [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: 01/08/2024] [Revised: 02/10/2024] [Accepted: 02/13/2024] [Indexed: 04/10/2024] Open
Abstract
Glaucoma is a common and potentially blinding complication of uveitis. Many mechanisms are involved alone or in combination in the pathogenesis of uveitic glaucoma (UG). In terms of diagnostic evaluation, the effects of inflammatory activity in the retinal nerve fiber layer may be a source of bias in the interpretation of optical coherence tomography measurements. For the successful treatment of UG, the control of intraocular inflammation specific to the cause or anti-inflammatory treatment, combined with IOP management, is mandatory. The early institution of specific treatment improves the prognosis of UG associated with CMV. The young age of UG patients along with increased failure rates of glaucoma surgery in this group of patients warrants a stepwise approach. Conservative and conjunctival sparing surgical approaches should be adopted. Minimally invasive surgical approaches were proved to be effective and are increasingly being used in the management of UG along with the traditionally used techniques of trabeculectomy or tubes. This review aims to summarize the progress that recently occurred in the diagnosis and treatment of UG.

Clinical Report of the Effectiveness of Netasurdil in Patients with Uveitic Glaucoma. Ocul Immunol Inflamm 2024; 32:2-4. [PMID: 36413271 DOI: 10.1080/09273948.2022.2145313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 11/03/2022] [Indexed: 11/24/2022]
Abstract
The use of netasurdil 0.02% (Rhopressa) in patients with primary open-angle glaucoma has been shown to be effective in lowering intraocular pressure (IOP). However, the effectiveness of netasurdil in patients with secondary forms of glaucoma has been minimally investigated. Previous reports have suggested its adequacy in lowering IOP in patients with congenital glaucoma. Its effectiveness in treating uveitic glaucoma, on the other hand, has yet to be formally examined. In a small group of patients with uveitic glaucoma, netasurdil has been shown to lower IOP by an average of 10.0mmHg, with over half of patients exhibiting more than a 20% decrease in IOP after 12 months of treatment. No patients developed any serious complications from taking netasurdil, however, conjunctival hyperemia was present in 15% of the patient population. Early success of netasurdil in patients with uveitic glaucoma warrants further investigation to better understand its safety and effectiveness.

Abstract
Hypertensive anterior uveitis poses diagnostic challenges owing to its multiple potential etiologies. Cytomegalovirus (CMV) infection is an under-recognized cause that exhibits diverse clinical presentations. This case report focuses on the intricate diagnostic challenge encountered in a 66-year-old immunocompetent patient with CMV-induced hypertensive anterior uveitis. The patient's history, encompassing angle closure glaucoma and topiramate use, contributed to the hypertensive crisis. Initial management included intraocular pressure (IOP)-lowering medication, topiramate discontinuation, and bilateral phacoemulsification, successfully normalizing IOP. However, a subsequent recurrence prompted a detailed investigation. The identification of keratic precipitates and a synechial closed angle led to aqueous humor sampling and polymerase chain reaction (PCR) testing, unveiling the presence of CMV-DNA. Treatment led to a favorable response, resolving ocular inflammation and effectively controlling IOP. This case underscores the complexity of diagnosing and managing CMV-induced hypertensive anterior uveitis, emphasizing the critical role of a comprehensive approach in achieving successful outcomes.

Abstract
PURPOSE To evaluate the outcomes of gonioscopy-assisted transluminal trabeculotomy (GATT) in adult eyes with uncontrolled uveitic glaucoma. METHODS We reviewed 16 eyes from 13 patients. Surgical success was defined as intraocular pressure (IOP) reduction >20% from baseline or IOP between 5 and 21 mmHg by the 3-month visit while on a stable number or fewer IOP-lowering agents and no need for additional glaucoma surgery. RESULTS At 12 months, the cumulative success rate was 81%. Mean IOP was 37.8 ± 13.0 mmHg at baseline and 12.2 ± 3.0 mmHg at 12 months (68% reduction; p < .0001). The average number of glaucoma medications was 4.6 ± 1.3 at baseline and 2.2 ± 0.7 at 12 months (52% reduction; p < .0001). Transient hyphema was seen in 44% of eyes at 1 week. CONCLUSIONS This small retrospective study suggests that GATT is effective and safe as an initial surgical treatment for medically refractory glaucoma in uveitic adult eyes.

Abstract
PURPOSE To describe the two-year outcome of trabeculectomy in cytomegalovirus(CMV) anterior uveitis(AU). METHODS Records of 29 eyes of 29 consecutive CMV AU patients undergoing MMC-augmented trabeculectomy for uncontrolled IOP despite maximal tolerated topical medications were retrospectively reviewed. Treatment success was defined as IOP≤21 mmHg with same or reduced number of IOP-lowering medications compared to baseline, without systemic acetazolamide or further interventions for uncontrolled IOP. RESULTS Treatment success was 79.3% (23/29) at 24 months. Both median IOP and number of IOP-lowering medications dropped significantly from baseline (p < .01 and p < .001, all time-points, Wilcoxon sign-rank test, respectively), with 63.2% and 19.0% reduction in AU relapse/year and steroid use(p = .001 and 0.03, respectively), without sight-threatening sequelae. At 24 months, AU frequency was not significantly different between successful cases with and without ≥12-month use of topical ganciclovir (p = .51, Mann-Whitney U test). CONCLUSION MMC-augmented trabeculectomy was efficacious for IOP control in nearly 80% of CMV AU cases over two years.

Abstract
This study was performed to investigate the corneal endothelial cell density (CECD) reduction and treatment efficacy in patients with uveitic glaucoma treated by the ciliary sulcus placement of the Ahmed glaucoma valve (AGV). This retrospective study included 27 eyes of 27 patients with noninfectious uveitis who underwent the sulcus placement of the AGV. Each patient underwent a clinical assessment including a CECD measurement before surgery and at 3, 6, 9, and 12 months after surgery. The mean CECD was 2431.4 ± 367.5 cells/mm2 at preoperative baseline and 2360.5 ± 391.3 cells/mm2 at 12 months (p = 0.074), with a reduction rate of 2.73 ± 9.29%. The CECD reduction was significantly greater in patients with unilateral uveitis than that with bilateral uveitis. The rate of successful intraocular pressure control was 88% at 12 months, and the number of intraocular pressure-lowering medications was significantly reduced (p < 0.001). The current study showed that the implantation of an Ahmed tube into the ciliary sulcus provided stable intraocular pressure control in patients with glaucoma secondary to noninfectious uveitis, and CECD reduction was moderate in most patients at 12 months.

Abstract
Minimally invasive glaucoma surgeries (MIGS) and non-penetrating glaucoma procedures have changed the surgical management of glaucoma in recent years and are being explored in the management of uveitic glaucoma. Deep sclerectomy, Xen45 gel stent, gonioscopy-assisted transluminal trabeculotomy (GATT), trabectome, and canaloplasty are described in the literature as alternative surgeries that may work for uveitic glaucoma. While most of the published studies are retrospective case series, the results suggest success even in refractory cases and with less inflammation than more traditional surgeries.

Abstract
PURPOSE Evaluation of treatment efficacy of XEN45 gelstent for glaucoma secondary to Fuchs uveitis syndrome (FUS). METHODS This retrospective case series evaluated patients with glaucoma secondary to FUS, who underwent XEN45 implantation. Complete success was defined as IOP lowering of ≥ 20% and cutoff IOP at ≤18 mmHg. Success was qualified if additional glaucoma medication was necessary. Additional glaucoma surgery except for needling and open bleb revision was regarded as failure. RESULTS Twelve eyes of 12 patients were included. Qualified and complete success rates were 50% after one year (n = 10). Qualified success was achieved in 66.6% of patients with 33.3% of patients achieving complete success after two years (n = 6). CONCLUSIONS XEN45 implantation had some success in the treatment of glaucoma secondary to FUS, but needling was frequently necessary to improve outcome.

Abstract
PURPOSE To evaluate the clinical safety and efficacy of modified CO2 laser-assisted sclerectomy surgery (CLASS) in patients with uveitic glaucoma (UG) using primary open-angle glaucoma (POAG) patients for a comparison. METHODS This retrospective study included UG and POAG patients from the modified CLASS Study Group database. Intraocular pressure (IOP) and the number of glaucoma medications were compared between groups by the Wilcoxon test. The Kaplan-Meier method was used for survival analysis; complete success was defined as 5≤ IOP≤18 mmHg and a ≥ 20% reduction in IOP from baseline without medication. RESULTS Twenty-three and 25 eyes in UG and POAG groups were included. At the 12-month visit in both groups, the mean IOP and mean number of IOP-lowering medications were significantly reduced compared to baseline, with complete success rates of 60.9% and 64.0% in the UG and POAG groups (P = .859). CONCLUSIONS Modified CLASS yields similar outcomes for patients with UG and POAG.

Abstract
PURPOSE Microbiomes have immunoregulatory functions and may be involved in the pathophysiology of eye diseases. However, the effects of microbiomes on uveitic glaucoma (UG) and open-angle glaucoma (OAG) have not been sufficiently investigated. This study analysed differences in eyelid and buccal microbiomes between UG and OAG using metagenomic technology. METHODS Eyelid and buccal specimens were collected from 34 UG and 62 OAG patients. The taxonomic composition of the microbiome was determined via 16S rRNA gene sequencing, operational taxonomic unit analysis and diversity analysis. Differential gene expression analysis (DEG) and principal component analyses (PCoA) determined taxon differences between the microbiomes of the UG and OAG patients. Subgroup analysis according to age and baseline IOP was performed. RESULTS There was no significant difference in alpha-diversity between the microbiomes of UG and OAG patients. Further, PCoA revealed no differences in eyelid microbiome between the UG and OAG groups, but significant differences were found in buccal microbiome between the groups, especially in a subgroup of OAG patients with normal IOP. DEG analysis of the eyelid microbiome revealed various taxa differences, including the enrichment of Rhodococcus in UG samples over OAG samples. Taxa such as Lactobacillus and Proteus were significantly depleted (q-value = 9.98e-6 and q-value = 1.38 × 10-4 , respectively) in the buccal microbiome of UG patients, whereas Enterococcus was enriched (q-value = 5.26e-5 ). CONCLUSIONS This study showed that the buccal microbiome in UG differs from that in OAG; reduced Lactobacillus was observed in UG. These results suggest that apart than OAG, microbiome composition may be a factor in the pathogenesis of UG.

Abstract
Herpetic anterior uveitis-associated ocular inflammation is commonly manifested with ocular hypertension and glaucoma. Relative to other viruses, cytomegalovirus (CMV) positive hypertensive anterior uveitis is associated with high recurrences of uveitis, as well as with uncontrolled intraocular pressure (IOP) and a subsequent higher requirement for future glaucoma surgery. To gain novel insights into the pathogenesis of ocular hypertension in these patients, we investigated the proteome changes of the aqueous humor (AH) derived from the CMV hypertensive anterior uveitis (CMV-HAU; n = 10) patients and non-glaucoma (cataract; n = 10) patients using liquid chromatography with tandem mass spectrometry. Among a total of 562 proteins identified, fifty and fifteen proteins were significantly elevated and decreased, respectively, in the AH of CMV-HAU patients compared to the control subjects by ≥2 fold. Gene ontology (GO) enrichment and network analyses of elevated proteins revealed that the enrichment of protein was involved in the complement activation, the humoral immune response mediated by the circulating immunoglobulins, proteolysis, and platelet degranulation. In the AH of CMV-HAU, GDF (growth/differentiation factor)-15, the inflammatory marker belonging to the TGF-β superfamily proteins, was significantly increased, while vasorin, an anti-TGF-β protein, levels were decreased. The trabecular meshwork cells infected with CMV exhibited a significantly increased expression of inflammatory markers. Collectively, these data indicate increased complement factor associated inflammation and humoral immunity in CMV-HAU associated ocular hypertension.

Abstract
Childhood glaucoma represents a heterogenous group of rare ocular conditions that may result in significant sight threatening complications related to elevated intraocular pressure (IOP). It can be classified as either primary or secondary and the latter may have systemic associations. This review will be based on the work of the childhood glaucoma research network (CGRN) and will focus on the diagnosis and management of the most common types of childhood glaucoma. These include primary congenital glaucoma (PCG) and juvenile open angle glaucoma (JOAG) as well as secondary causes of glaucoma associated with non-acquired ocular anomalies (Axenfeld-Rieger anomaly; Peters anomaly and Aniridia), glaucoma associated with systemic disease (Sturge Weber syndrome and Neurofibromatosis), those due to acquired conditions (Uveitic glaucoma, trauma and tumours) and importantly glaucoma following cataract surgery.

Abstract
Purpose To study the effects of perioperative uveitis control (PUC) on postoperative intraocular pressure (IOP) and uveitis activity in uveitic glaucoma (UG) patients who required glaucoma surgeries. Patients and Methods A retrospective chart review of 109 patients (120 eyes) which had glaucoma surgery for UG. A total of 66 eyes which had PUC were compared to 54 eyes which did not have. Measurements of IOP and uveitis activity were recorded preoperatively and over 2 years postoperatively. Average number of antiglaucoma medications and frequency of surgical failure were obtained in both groups. Results Over 2 years postoperatively, average IOP was lower in eyes which had PUC. Significant differences in IOP were found at 3 months (P = 0.004), 6 months (P = 0.001), 1 year (P < 0.001), and 2 years (P < 0.001). Lower grades of anterior chamber (AC) inflammation were found in eyes which had PUC. Significant differences were found at 1 month (P < 0.001), 3 months (P < 0.001) and 6 months (P = 0.001). Mean number of antiglaucoma medications at last visit was 0.7 ± 1.1 for eyes which had PUC and 2.6 ± 1.5 for eyes which did not have PUC (P < 0.001). Among eyes which had PUC, only two eyes required second glaucoma surgeries, while 16 eyes with no PUC required further glaucoma surgeries after 27.7 ± 12.5 months (P < 0.001). Conclusion Proper PUC in patients going for UG surgeries results in lower IOP levels and less AC inflammation over 2 years postoperatively. A comprehensive PUC regimen is needed for uveitic glaucoma patients going for surgeries. ![]()

Abstract
PURPOSE We performed a meta-analysis to evaluate the effect of uveitis treatment on glaucoma drainage implant surgical outcomes. METHODS We included 16 articles in the meta-analysis. Two groups were defined based on medical therapy of uveitis: Group 1: poorly controlled uveitis, and Group 2: well-controlled uveitis including use of immunomodulatory medications. RESULTS The two groups were similar in comparisons of follow-up time, age, gender, and etiology of uveitis. Meta-analysis demonstrated significantly greater success in Group 2 (95.1%) compared to Group 1 (81.6%) at 1 year after glaucoma drainage implant surgery (P = .001). The final success was significantly greater (P 0.014) in group 2 compared with group 1 (86.1% and 74.3%, respectively). CONCLUSION Surgical success was significantly higher in uveitic glaucoma patients treated with more intensive immunosuppressive therapy before and after glaucoma drainage implant surgery. The level of control of uveitis perioperatively appears to influence glaucoma drainage implant surgery outcomes.

Abstract
BACKGROUND To review the changes in intraocular pressure (IOP) following topical hypotensive medications washout in patients with primary open angle glaucoma (POAG), ocular hypertension (OHT) and uveitic glaucoma (UG)/OHT. METHODS The study included 120 patients with POAG, OHT and UG recruited from prospective clinical trials between February 2013 and July 2017. We excluded 20 eyes with IOP of ≤21 mm Hg, 11 eyes with previous incisional surgery and 17 eyes with incomplete data. UG eyes with active inflammation and on steroid treatment were excluded. Participants underwent a 1-month washout period from topical ocular hypotensive medications before IOP phasing. Comparisons were made between pre/post-washout IOP, and highest-recorded (peak) and post-washout IOP. RESULTS A total of 110 eyes with POAG, 33 eyes with OHT and 43 eyes with UG were included for analysis. The mean pre-washout IOP was 18.1±3.3 mm Hg in POAG, 18.8±3.3 mm Hg in OHT and 17.9±8.8 mm Hg in UG; the mean post-washout IOP was 26.6±4.8 mm Hg, 26.4±3.9 mm Hg, 23.1±10.1 mm Hg in POAG, OHT and UG, respectively. The mean increase in IOP after washout was significantly lower in UG compared with POAG and OHT eyes (p=0.01). The percentage of eyes with post-washout IOP <22 mm Hg was 12.7% in POAG, 6.1% in OHT and 51.2% in UG. CONCLUSION Active inflammation and steroid treatment contributes to elevated IOP in uveitis. Therefore, IOP may revert to normal once inflammation subsides. We recommend ocular hypotensive treatment washout to be considered in UG eyes that have IOP under control in the absence of recurrence of uveitis.

Abstract
Uveitic glaucoma is a range of disorders that results in optic nerve damage from elevated intraocular pressure secondary to intraocular inflammation. As compared to primary open angle glaucoma, uveitic glaucoma is associated with a more aggressive disease course caused by very high intraocular pressure levels that wax and wane. Diagnosis is often based on clinical presentation, disease course, and associated systemic manifestations. Diagnostic imaging plays an important role in both diagnosis and management. While the mechanisms of uveitic glaucoma vary, treatment requires strict control of the inflammation and may involve additional intraocular pressure lowering techniques. Management often dictates an interdisciplinary approach as systemic association and treatment is common. When topical management does not slow the progression of optic nerve damage and vision loss, surgical intervention is required. A significant portion of patients with uveitic glaucoma will eventually require surgical intervention and the appropriate referrals should be made. By nature, success rates of surgical intervention in uveitic glaucoma patients are lower than non-inflammatory causes of elevated intraocular pressure and glaucomatous damage. Chronic inflammation, multiple mechanisms, systemic associations, and unpredictable response to treatment make uveitic glaucoma challenging to manage. This review will discuss the pathophysiology, diagnosis, and management of uveitic glaucoma to provide a guide for eye-care providers.

[PMID: 29675382 PMCID: PMC5902368 DOI: 10.18240/ijo.2018.04.15] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2017] [Accepted: 01/29/2018] [Indexed: 12/14/2022] Open
Abstract
AIM To report long-term outcomes of secondary glaucoma due to uveitis treated with Ahmed glaucoma valve (AGV) implantation in a series of Chinese patients. METHODS The retrospective study included 67 eyes from 56 patients with uveitic glaucoma who underwent AGV implantation. Success of the treatment was defined as patients achieving intraocular pressure (IOP) levels between 6 and 21 mm Hg with or without additional anti-glaucoma medications and/or a minimum of 20% reduction from baseline IOP. The main outcome measurements included IOP, the number of glaucoma medications at 1, 3, 6, 12, 24, 36, 48 and 60mo after surgery, surgical complications, final best-corrected vision acuity (BCVA), visual field (VF) and retinal nerve fiber layer (RNFL). RESULTS The mean follow-up was 53.3±8.5 (range 48 to 60)mo. The cumulative probability of success rate was 98.5%, 95.5%, 89.6%, 83.6%, 76.1%, 70.1%, 65.7% and 61.2% at 1, 3, 6, 12, 24, 36, 48 and 60mo, respectively. IOP was reduced from a baseline of 30.8±6.8 to 9.9±4.1, 10.1±4.2, 10.9±3.7, 12.9±4.6, 13.8±3.9, 13.2±4.6, 12.3±3.5 and 13.1±3.7 mm Hg at 1, 3, 6, 12, 24, 36, 48 and 60mo, respectively (P<0.01). The number of postoperative glaucoma medications was significantly decreased compared with baseline at all time points during the study period (P<0.05). There was no significant difference between preoperative and postoperative BCVA. Remarkable surgical complications were not found after surgery. The VF and RNFL of the patients were stable after the surgery. CONCLUSION AGV implantation is safe and effect in terms of reducing IOP, decreasing the number of glaucoma medications, and preserving vision for patients with uveitic glaucoma.

Outcomes of severe uveitic glaucoma treated with Baerveldt implant: can blindness be prevented? Acta Ophthalmol 2018; 96:24-30. [PMID: 28921906 DOI: 10.1111/aos.13489] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2016] [Accepted: 03/30/2017] [Indexed: 11/30/2022]
Abstract
PURPOSE To evaluate long-term outcomes on efficacy and safety of severe uveitic glaucoma treated with a Baerveldt glaucoma implant (BGI). METHODS A retrospective study of 47 eyes of 47 patients with uveitic glaucoma treated by a BGI between September 2002 and September 2015. Main outcome measures were intraocular pressure (IOP), number of glaucoma medications, course of the uveitis, visual acuity (VA) and complications. RESULTS Mean IOP dropped from 30.6 ± 8.1 mmHg with 3.6 ± 1.1 glaucoma medications at baseline to 10.6 ± 4.3 mmHg with 1.0 ± 1.3 glaucoma medications after a mean follow-up of 63.6 ± 43.1 months. In the majority of cases, IOP remained stable during follow-up. However, especially in several patients with viral uveitis, episodes with IOP peaks were observed during a flare-up despite a functioning implant. These peaks remained below preoperative levels. During follow-up, 16 patients (34%) experienced a clinically significant VA loss, mainly because of late-stage glaucoma or hypotony maculopathy. Early postoperative complications were transient choroidal effusion (n = 5), shallow/flat anterior chamber (n = 4), hyphaema (n = 2) and suprachoroidal haemorrhage (n = 1). The most important late postoperative complication was hypotony maculopathy (n = 5), three of these in juvenile idiopathic arthritis (JIA) patients. CONCLUSION The BGI is an effective and safe treatment for patients with refractive secondary glaucoma due to uveitis. In a majority of patients, VA remains stable and a low and stable IOP is maintained over time with an acceptable number of complications. In particular, patients with viral uveitis and glaucoma should be closely monitored for IOP peaks that may occur during episodes of a flare-up of uveitis, whereas at the other end of the spectrum, patients with JIA seem much more prone to hypotony maculopathy.

Abstract
Background The aim of this study was to compare the long-term outcomes of ab externo trabeculotomy in primary open-angle glaucoma (POAG) and uveitic glaucoma (UG). Design This was a retrospective single-center case series study. Participants Twenty eyes of 17 patients with POAG and 22 eyes of 18 patients with UG were included in this study. Patients and methods The medical records of all consecutive patients with POAG and UG who underwent ab externo trabeculotomy since 2004 were reviewed. Main outcome measure The main outcome measure was change in median intraocular pressure (IOP). Success was defined as IOP ≤21 mmHg (success 1) and IOP ≤21 mmHg and at least 25% reduction from baseline (success 2). Results In the POAG group, the median IOP decreased significantly from 22 mmHg (95% CI 21–25 mmHg; n=20) at baseline to 14 mmHg (95% CI 12–16; n=13) after 4 years, P<0.001. In the UG group, the median IOP decreased significantly from 27 mmHg (95% CI 24.5–30.5 mmHg; n=22) at baseline to 12 mmHg (95% CI 9–15 mmHg; n=15) after 4 years, P<0.001. Seven eyes in the UG group failed within the first year after surgery compared to none in the POAG group. Of these, four eyes had Fuchs’ uveitis syndrome and two had granulomatous uveitis. No sight-threatening complications occurred in both POAG and UG groups. Conclusion Ab externo trabeculotomy effectively reduced IOP in both UG and POAG groups. However, the success rates in the UG group were significantly lower due to the high failure rate in patients with Fuchs’ uveitis syndrome and granulomatous uveitis. The procedure demonstrated a high safety profile in both UG and POAG patients.

Abstract
PURPOSE To compare latanoprost/timolol (LT) versus travoprost/timolol (TT) fixed combinations for ocular hypertension (OHT) associated with uveitis. METHODS Thirty-six patients (55 eyes) who were treated with LT (28 eyes) or TT (27 eyes) for OHT associated with uveitis were reviewed retrospectively. Intraocular pressure (IOP) and inflammation scores at the initiation of treatment and at the last visit during therapy were analyzed. RESULTS Although IOP was reduced significantly in both LT and TT groups, the reduction rate was significantly greater with TT group than with LT. The differences in the reduction of IOP between the groups remained significant when the cases were classified into inflammation-induced OHT and steroid-induced OHT. Inflammation score was not exacerbated by LT or TT treatment. CONCLUSIONS Both LT and TT are safe and effective for the treatment of OHT associated with uveitis and greater IOP reduction may be achieved by TT than by LT treatment.

Abstract
Purpose To assess ocular hypertension (OHT) and hypotony as outcomes of uveitis in patients managed in a mid-Atlantic tertiary care center. Methods Retrospective, observational study of uveitis patients seen at the University of Virginia from 1984 to 2014. Results A total of 442 patients (582 eyes) with uveitis were identified and included in the study. The patient population was 57.0% female. Overall, 61.9% were Caucasian and 26.6% were African American. Mean age was 46.8 years. Overall, 11.5% of the eyes had OHT at initial visit, and 7.9% had OHT at final visit (P=0.035). For each additional decade of life, the odds that an eye had OHT were elevated by a factor of 1.15 (95% confidence interval [CI]: [1.02, 1.30], P=0.027) at initial visit and by a factor of 1.15 (95% CI: [1.00, 1.32], P=0.055) at final visit. The odds that an anterior uveitis eye had OHT were greater by a factor of 2.50 (95% CI: [1.22, 5.14], P=0.013) than the odds for a nonanterior uveitis eye at initial visit and greater by a factor of 2.61 (95% CI: [1.24, 5.50], P=0.011) at final visit. For each additional 0.5 logarithm of the minimum angle of resolution increase in initial visual acuity, the odds that an affected eye had OHT were elevated by a factor of 1.18 (95% CI: [1.00, 1.39], P=0.047) at initial visit and 1.23 (95% CI: [0.99, 1.54], P=0.065) at final visit. Overall, 21 of 582 eyes (3.6%) were hypotonous initially, while 24 of 582 eyes (4.1%) were hypotonous at final follow-up (P=0.631). Conclusion OHT was associated with increasing age, anterior uveitis, and poor presenting visual acuity. Ocular hypotony was more common in anterior uveitis than in nonanterior uveitis. Fluctuations in intraocular pressure are an important cause of visual impairment in patients with uveitis. Careful monitoring of all uveitis patients, and especially those most at risk for fluctuations in intraocular pressure, can preserve vision and improve patient outcomes.

Abstract
AIM To analyze current understanding of the factors that contribute to raised intraocular pressure (IOP) in patients with uveitis. METHODS A pubmed literature review was carried out using words including "uveitic glaucoma", "IOP AND uveitis", "ocular hypertension AND uveitis", "inflammation AND glaucoma", "aqueous dynamics" AND "glaucoma/uveitis". RESULTS Of the two studies looking at the aqueous dynamics in experimentally induced uveitis, both found aqueous flow decreased acutely, and one found that uveoscleral outflow increased. This is likely to reflect the types of uveitis that present acutely with hypotony. A study examining patients with Fuch's heterochromic cyclitis found no difference in aqueous flow or uveoscleral outflow. No studies have examined aqueous dynamics in types of uveitis that present with acutely raised IOP. Levels of prostaglandins rise in acute uveitis, which has been shown to increase uveoscleral and trabecular outflow, without affecting aqueous flow. Studies have demonstrated that raised levels of trabecular protein reduce trabecular outflow. Steroid treatment, inflammatory cells, free radicals and enzymes are also likely to contribute to the development of raised pressure. When considering the impact of the pathogenesis of raised pressure in uveitis on its treatment, prostaglandins may provide good intraocular pressure control, but there are concerns regarding their theoretical ability to worsen the inflammatory response in uveitis. Studies have not conclusively proven this to be the case. Surgical success rates vary, but trabeculectomy plus an antimetabolite, deep sclerectomy plus an antimetabolite, and Ahmed valve surgery have been used. CONCLUSIONS Uveitic glaucoma is caused by a number of different diseases, some of which present with acute hypotony, others with acutely raised IOP, and others which demonstrate an increase in IOP over time. Further studies should be carried out to examine the differing pathogenesis in these types of diseases, and to establish the best treatment options.

Abstract
AIM The aim of this report was to present a case of varicella zoster virus (VZV)-associated anterior uveitis, which developed in an adult who was seronegative for anti-VZV antibodies. CASE PRESENTATION A 66-year-old male patient was referred to the National Defense Medical College, Tokorozawa City, Japan with iridocyclitis in his right eye. On examination, intraocular pressure was 30 mmHg in the right eye, and biomicroscopy revealed ciliary injection, corneal epithelial edema, mutton fat keratic precipitates, flare, and infiltrating cells in the anterior chamber. Serological tests were negative for anti-VZV antibodies, but VZV-DNA copies of 1.28×10(7) copies/mL were detected by quantitative reverse transcriptase polymerase chain reaction using the aqueous humor obtained from the right eye. Iridocyclitis was reduced by administration of oral valaciclovir in addition to corticosteroid eye drops, and serum anti-VZV antibodies were first detected after 4 months' administration. When ocular inflammation was resolved after 6 months, VZV-DNA could not be detected in the aqueous humor any more. CONCLUSION VZV-associated uveitis may develop in an adult with undetectable serum anti-VZV antibodies. Multiplex polymerase chain reaction of the aqueous humor is the key investigation necessary for the diagnosis in such cases.

Abstract
Purpose To investigate the characteristics of uveitic glaucoma (UG) and evaluate surgical treatments. Methods This study examined a retrospective, nonrandomized comparative interventional case series of 105 UG patients (141 eyes) followed between April 1, 2001 and July 30, 2014 at the outpatient clinic of Tohoku University Hospital. The study group included 47 patients (47 eyes) who underwent glaucoma surgery: trabeculectomy, trabeculotomy, and trabectome surgery. The analysis used Kaplan–Meier life tables, with surgical failure defined as intraocular pressure ≧21 mmHg or the need for additional glaucoma surgery. Results UG patients represented 9.73% of our database of glaucoma patients. The mean follow-up period was 40.32±32.53 months. Seventy-one patients had granulomatous uveitis (67.62%) and 34 had nongranulomatous uveitis (32.38%). The causes of uveitis included sarcoidosis (n=25), Behçet’s disease (n=11), Vogt–Koyanagi–Harada disease (n=9), Posner–Schlossman syndrome (n=12), herpes simplex virus infectious uveitis (n=7), acute anterior uveitis (n=5), intermediate uveitis (n=4), scleritis (n=4), inflammatory bowel disease (n=4), varicella zoster virus uveitis (n=2), and others (n=6). An additional 16 patients were diagnosed with idiopathic UG. Surgical success rates were 82.86% for trabeculectomy, 62.50% for trabeculotomy, and 75.00% for trabectome. Significant risk factors for surgical failure included male sex (P=0.02), age less than 45 years (P=0.0009), nongranulomatous uveitis (P=0.04), and postoperative inflammation (P=0.01). Conclusion Young male patients with nongranulomatous uveitis had a significant risk of surgical failure. Moreover, prolonged postoperative inflammation created a susceptibility to surgical failure, indicating the importance of postoperative inflammation reduction.
