RESUMO
A multitude of pharmacological compounds have been shown to lower and control intraocular pressure (IOP) in numerous species of animals and human subjects after topical ocular dosing or via other routes of administration. Most researchers have been interested in finding drug candidates that exhibit a relatively long duration of action from a chronic therapeutic use perspective, for example to treat ocular hypertension (OHT), primary open-angle glaucoma and even normotensive glaucoma. However, it is equally important to seek and characterize treatment modalities which offer a rapid onset of action to help provide fast relief from quickly rising IOP that occurs in certain eye diseases. These include acute angle-closure glaucoma, primary angle-closure glaucoma, uveitic and inflammatory glaucoma, medication-induced OHT, and other secondary glaucomas induced by eye injury or infection which can cause partial or complete loss of eyesight. Such fast-acting agents can delay or prevent the need for ocular surgery which is often used to lower the dangerously raised IOP. This research survey was therefore directed at identifying agents from the literature that demonstrated ocular hypotensive activity, normalizing and unifying the data, determining their onset of action and rank ordering them on the basis of rapidity of action starting within 30-60 min and lasting up to at least 3-4 h post topical ocular dosing in different animal species. This research revealed a few health authority-approved drugs and some investigational compounds that appear to meet the necessary criteria of fast onset of action coupled with significant efficacy to reduce elevated IOP (by ≥ 20%, preferably by >30%). However, translation of the novel animal-based findings to the human conditions remains to be demonstrated but represent viable targets, especially EP2-receptor agonists (e.g. omidenepag isopropyl; AL-6598; butaprost), mixed activity serotonin/dopamine receptor agonists (e.g. cabergoline), rho kinase inhibitors (e.g. AMA0076, Y39983), CACNA2D1-gene product inhibitors (e.g. pregabalin), melatonin receptor agonists, and certain K+-channel openers (e.g. nicorandil, pinacidil). Other drug candidates and targets were also identified and will be discussed.

BACKGROUND: Iris mammillation is a rare disease characterized by the distribution of multiple nodules on the iris surface. The course of uveitic glaucoma with iris mammillation has never been reported. CASE PRESENTATION: A 56-year-old woman, who presented with unilateral decreased vision, visited our hospital for treatment of uveitic glaucoma in the right eye. Multiple nodules were scattered over the iris surface in that eye. This case was diagnosed as iris mammillation on clinical findings. After excluding malignant tumors such as melanoma, trabeculectomy was performed. The resected iris had no pathologically malignant findings. The iris nodules evolved to a sand-like appearance, and the intraocular pressure remained stable without recurrent inflammation 7 years after trabeculectomy. CONCLUSIONS: In a case of unilateral uveitic glaucoma with iris mammillation, filtration surgery was performed after excluding the presence of a malignancy, and the long-term postoperative course has been stable.

BACKGROUND: To discuss the first case of mitomycin C (MMC) toxicity after XEN® gel stent implantation in a glaucoma patient, conducted using the XEN "air" technique with an ophthalmic viscosurgical device (OVD). CASE PRESENTATION: A 44-year-old Asian male presented with increased intraocular pressure (IOP; 52 mmHg) accompanied by keratic precipitates and an edematous cornea. He was diagnosed with uveitic glaucoma in the left eye, and the IOP was controlled with a topical anti-glaucoma agent. However, glaucoma progression was revealed by Humphrey visual field (HVF) and optical coherence tomography (OCT) examinations. The patient underwent uneventful XEN gel stent implantation using the XEN air technique and an MMC (0.02%, 0.1 mL) injection, with subconjunctival air and OVD injection provided prior to XEN implantation in the left eye. The patient exhibited a decreased IOP (11 mmHg), elevated bleb, and extensive subconjunctival hemorrhage on postoperative day 1. On postoperative day 18, diffuse conjunctival injection and a large avascular bleb was noticed around the XEN gel stent. The patient complained of severe eye pain and discomfort, suggestive of MMC toxicity, and the IOP was 12 mmHg. The patient was treated with a topical steroid and antibiotics tapered over a 6-month period. Finally, the toxicity was successfully controlled, with the IOP stabilizing at around 15 mmHg. CONCLUSIONS: Although significantly greater lowering of the IOP can be expected with the use of subconjunctival OVD injection and MMC during XEN gel stent implantation, a cautious approach and a longer monitoring period are required.

INTRODUCTION: Uveitic glaucoma remains challenging despite medical and surgical advancements and can potentially lead to blindness if left uncontrolled. Conservative alternatives as well as microinvasive surgeries can postpone the necessity of a highly invasive intervention. However, such procedures are still necessary to treat some refractive glaucoma cases. Since previous studies have reported excellent results following the primary implantation of glaucoma drainage devices, it was our study's aim to evaluate long-term results following a Baerveldt 250 implantation in highly complex and surgically burdened uveitic glaucoma eyes (UG) and compare these to a similar population suffering from other forms of glaucoma (OFG). MATERIAL AND METHODS: We performed a retrospective analysis of all eyes (UG vs. OFG) following a Baerveldt 250 implant between 2013 and 2019. Efficacy parameters as well as post-operative complication data were extracted from our electronic data system for statistical analysis. RESULTS: A total of 62 eyes were included in our study (24 UG and 38 OFG). UG baseline mean IOP was 35.04 mmHg (± 11.85 mmHg) with 3.08 (± 1.13) topical agents, and OFG was 32.63 mmHg (± 7.74 mmHg) with 2.68 (± 1.28) topical agents. A majority of eyes also required systemic acetazolamide (UG: 79% OFG: 87%) and had undergone at least one glaucoma-related operation prior to the Baerveldt 250 implant ((UG: 1.21 (± 0.66)), OFG: 1.74 (± 1.33)). At the median follow-up period (UG 592, OFG 764 days), 52.5%/32.5% of UG/OFG cases showed qualified success (IOP below 21 mmHg with either topical or/and systemic medication), 15%/30% no longer required topical medication, and 47.5% /47.5% were free of acetazolamide systemically. Moreover, 75%/72.5% of eyes experienced no further pressure-related surgical event. Although sight-threatening complications such as corneal and macular edema were reported in both groups, most either maintained or improved their visual acuity at the last follow-up (58.33%/57.89%). CONCLUSION: The Baerveldt 250 implant is shown to be both effective and safe for advanced glaucoma cases in uveitis and other forms. No further glaucoma-related surgery is required in the majority of eyes in either group within a follow-up period of almost 2 years. Despite sight-threatening complications such as macular and corneal edema, visual acuity can be either maintained or improved in most eyes.

BACKGROUND: The microbiome could trigger inflammation leading to epigenetic changes and is involved in the pathophysiology of eye diseases; however, its effect on uveitic glaucoma (UG) has not been fully investigated. This study analysed the differences in eyelid and buccal microbiomes in patients with UG using next-generation sequencing. METHODS: The eyelid and buccal specimens of 34 UG and 25 control patients were collected. The taxonomic composition of the microbiome was obtained via 16S ribosomal DNA sequencing. Diversity and differential gene expression analyses (DEG) determined taxon differences between the microbiomes of UG and control groups. RESULTS: In both the eyelid and buccal microbiomes, alpha-diversity was lower in UG patients than controls, while beta-diversity in patients with UG was higher than in controls. DEG analysis of the eyelid microbiome revealed various taxa differences, including enrichment of Paenibacillus and Dermacoccus (p-value, 1.31e-6 and 1.55e-7, respectively) and depletion of Morganella and Lactococcus (p-value, 6.26e-12 and 2.55e-6, respectively) in patients with UG. In the buccal microbiome, taxa such as Lactococcus was significantly depleted (p-value, 1.31e-17), whereas Faecalibacterium was enriched in patients with UG (p-value, 6.12e-8). CONCLUSIONS: The eyelid and buccal microbiomes in patients with UG differ from controls, which raises concerns surrounding environmental influences on the pathogenesis of UG. The reduced Lactococcus in the eyelid and buccal area suggest that microbiota dysbiosis is associated with UG.

BACKGROUND: We aimed to analyze the clinical characteristics of secondary glaucoma related to cytomegalovirus (CMV)- and varicella zoster virus (VZV)-positive uveitis. METHODS: In this retrospective study, we enrolled patients with anterior uveitic secondary glaucoma. All the patients underwent aqueous and serum analyses for viral antibody through enzyme-linked immunosorbent assay. Among the 60 included patients, 22 had CMV-negative Posner-Schlossman syndrome (CMV-negative PSS), 25 had CMV-positive PSS, and 13 had VZV-positive anterior uveitis secondary glaucoma (VZV-AUSG). We evaluated the following main indicators: age, disease duration, intraocular pressure (IOP), cup-to-disc ratio, best corrected visual acuity (BCVA), corneal endothelial cell (CEC) count, ocular morphological changes, and medical treatments. RESULTS: We found that 53.2% (25/47) patients with PSS were CMV-positive. Patients with CMV-positive PSS had a larger cup-to-disc ratio (p = .043), lower CEC density (p = .017), more severe CEC loss (p < .001), and more iris depigmentation (p = .006) than CMV-negative PSS patients. Compared with patients with CMV-positive PSS, those with VZV-AUSG were older (p = .003), presented a higher IOP (p = .015), and had poorer BCVA (p < .001). Patients with CMV-positive PSS and VZV-AUSG all accepted ganciclovir treatment, and those with CMV-positive PSS used fewer antiglaucoma agents simultaneously compared with CMV-negative PSS (p = .005) and VZV-AUSG (p < .001). All three groups had a comparable proportion of patients requiring antiglaucoma surgery. CONCLUSIONS: We observed some distinctive clinical features in CMV-positive PSS compared with CMV-negative PSS. Further, we found that patients with VZV-AUSG presented with a higher IOP and worse visual acuity, and required more antiglaucoma medication than those with CMV-positive PSS.

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.

This study compared the efficacy of modified CO2 laser-assisted sclerectomy surgery (CLASS) with combined CLASS and trabeculectomy (CLASS-TRAB) in patients with uveitic glaucoma (UG). UG patients who underwent CLASS-TRAB between August 2015 and April 2019 were retrospectively compared with a control group who underwent a modified CLASS standalone procedure during the same period. Visual acuity, intraocular pressure (IOP), use of supplemental medical therapy and postoperative complications were recorded at baseline, 1 week, 3 months, 6 months and 12 months. Forty patients (40 eyes) were enrolled, and each group had 20 patients (20 eyes). The age and sex distribution were matched between groups (P > 0.05). Both the preoperative IOP (CLASS: 34.9 ± 9.3 mmHg, CLASS-TRAB: 36.8 ± 8.7 mmHg; P > 0.05) and number of glaucoma medications (CLASS: 3.3 ± 0.4, CLASS-TRAB: 3.5 ± 0.5; P > 0.05) were relatively higher in the CLASS-TRAB group than in the CLASS group. At the final follow-up, the IOP (CLASS: 12.9 ± 3.4 mmHg, CLASS-TRAB: 11.2 ± 2.5 mmHg) and number of glaucoma medications (CLASS: 0.4 ± 0.7 and CLASS-TRAB: 0.2 ± 0.5) significantly decreased in both groups (P < 0.01). Both the complete success rate and qualified success rate were comparable between the two groups (CLASS versus CLASS-TRAB: 55% versus 80%, P = 0.09; 80% versus 95%, P = 0.34). CLASS-TRAB is as efficient as modified CLASS in terms of the IOP-lowering effect, providing a new option for patients with UG that is severe and ineligible for other treatments.

PURPOSE: To evaluate the effect of tube shunt type [Ahmed (AGV) versus Baerveldt (BGI)] on the frequency of tube-cornea touch and corneal decompensation after tube shunt surgery. METHODS: This retrospective comparative study included 145 eyes of 130 patients with uveitic glaucoma who underwent AGV (75 eyes) or BGI (70 eyes) implantations. Electronic medical records were reviewed to document demographic factors, intraocular pressure (IOP) reduction, frequency of tube-cornea touch, corneal decompensation, and need for subsequent corneal transplantation. RESULTS: The mean follow-up was 27.7±3.3 months for AGV and 32.8±3.8 months for BGI (p=0.30). Tube-cornea touch was observed in 5 eyes after BGI and 1 eye in the AGV group (p=0.08). The BGI group reported a significantly higher rate of corneal decompensation (9 versus 0; p=0.001) and transplantation (6 versus 0; p=0.01) compared to the AGV group. Previous trabeculectomy was a significant risk factor for corneal complications in eyes undergoing BGI implantation (odds ratio [OR]= 8.17, 95% confidence interval [CI]=1.78-37.45, p=0.007). CONCLUSION: Similar rates of tube-cornea touch were observed in both shunt types; BGI shunts were associated with a greater incidence of corneal complications and transplantation as compared to AGV in this retrospective series of uveitic glaucoma cases.

BACKGROUND: Uveitic glaucoma commonly leads to a more intense optic nerve damage than other types of glaucoma, causing glaucomatous optic nerves and visual field defects. Anterior uveitis is the most commonly associated risk factor. Surgical intervention is usually indicated when all medical treatment has failed. We report five-year results for 16 eyes of uveitic glaucoma managed with viscocanalostomy (VC)/Phaco viscocanalostomy (PVC). METHODS: Retrospective analysis on all uveitic glaucoma cases meeting a five-year follow up was completed. All patients were managed surgically with either viscocanalostomy (VC) or phacoviscocanalostomy (PVC). Outcomes evaluated included intraocular pressures measurement pre-listing, on day 1, year 1 to year 5. Complete success rate was defined as achieving an intraocular pressure (IOP) lower than 21 mmHg or reduced by 30% without medications, and qualified success was achieved when IOP was lower than 21 mmHg or a reduction in IOP of 30% with topical medical therapy ± Laser goniopuncture (LGP). If further surgeries were required to reduce IOP due to glaucoma progression then they were classified as a failure. RESULTS: A total of 16 patients with uveitic glaucoma were reviewed. Complete success was seen in 75% of patients at year 1, 50% of patients at year 3 and 19% of patients in year 5. Conversely qualified success was achieved in 94% of patients at year 1, 86% of patients at year 3 and 75% of patients at year 5. In the group of patients requiring further surgery, 50% of patients had previous surgeries, including cataract surgery, trabeculectomy and viscocanalostomy. There was a mean number of 4 pre-operative drops before their primary surgery and a mean drop in eye medications of 1.1 at 5 years follow-up. Success rates were prognostically linked to lower mean number of interventions and lower percentage of previous surgeries. CONCLUSION: There remains a significant paucity of information in the utilization of PVC in uveitic glaucoma. The advantage of nonpenetrating glaucoma surgery (NPGS) includes the lack of entry into the anterior chamber and the avoidance of an iridectomy which may reduce intraocular inflammation and postoperative complications. Our study shows that non-penetrating surgery is successful in treating advanced uveitic glaucoma.

PURPOSE: To investigate the types, frequency and clinical profiles of uveitic glaucoma seen at a tertiary care center and also to have an idea about the distribution of uveitic glaucoma types in Turkish population. METHODS: Consecutive case notes of all patients attending a specialized uveitis clinic over a 3-month period were reviewed retrospectively. RESULTS: One hundred and seven eyes of 96 patients were included. Sixty-five of the eyes had anterior, one intermediate, nine posterior uveitis while 32 of them had panuveitis. Twenty-three eyes had acute, 52 chronic and 32 recurrent uveitis. Herpes virus associated iridocyclitis was the leading cause of anterior uveitis-associated uveitic glaucoma followed by cytomegalovirus (CMV) associated anterior uveitis; while steroid-induced glaucoma accounted for the majority of chronic uveitis with glaucoma followed by Fuchs' uveitis syndrome (FUS). The most common causes of glaucoma among the cases were steroid-induced in 30 eyes (28%), Herpes virus anterior uveitis in 24 eyes (22%), CMV anterior uveitis in 20 eyes (18%), FUS in 15 eyes (14%), ocular toxoplasmosis in 5 eyes (4%). Behçet's uveitis was the most common (n = 11, 36%) cause of steroid-induced glaucoma. The need for surgical intervention was 23.32% (n = 25; 12 of them were FUS, 8 steroid-dependent, 1 HSV and 3 CMV anterior uveitis and 1 angle closure glaucoma with idiopathic uveitis) in our cases. CONCLUSION: Uveitic glaucoma is a common complication in a tertiary clinic. The most common causes are steroid-induced, FUS, viral anterior uveitis. The most common disease causing steroid induced glaucoma was Behçet's disease. Glaucoma surgery is required in a significant number of cases.

PURPOSE: To evaluate the efficacy of long-tube shunt surgery (LTSS) without valve in uveitic glaucoma (UG) eyes. METHODS: We retrospectively analyzed the data of 45 UG eyes that underwent only LTSS or LTSS combined with trabeculectomy (TLE) (LTSS/TLE). The UG eyes were analyzed by categorizing them into granulomatous/non-granulomatous, steroid responder/non-responder, and primary open-angle glaucoma (POAG) (POAG background)/non-POAG (non-POAG background). All granulomatous UG eyes received a continuous 3-times-daily administration of topical betamethasone post-LTSS. RESULTS: The eyes consisted of granulomatous (37 eyes, 82%)/non-granulomatous (5 eyes, 11%), steroid responder (19 eyes, 42%)/non-steroid responder (13 eyes, 29%), and 20 eyes with POAG or POAG background (p = 0.0022, 83%) among 24 cases of unilateral UG. The 5-year survival rates of only LTSS and LTSS/TLE were 66% and 100%, respectively. Kaplan-Meier survival-curve estimates in the non-granulomatous group were 100% for 6-year postoperative period, while the granulomatous group showed a gradual decrease along the 6-year (81%) postoperative period. The 5-year survival rates in the steroid responder group and the non-steroid responder group eyes were 74% and 78%, respectively. No intraocular pressure (IOP) elevation was observed in the positive steroid responder eyes post-LTSS. CONCLUSIONS: LTSS and LTSS/TLE were both effective in UG. Positive steroid response may be masked by LTSS in the positive responder eyes. Continuous administration of topical betamethasone post-LTSS may be important for preventing an IOP spike by suppressing inflammation in the anterior chamber. LTSS combined with TLE may be recommended in eyes with granulomatous UG, and the coexistence of a POAG/POAG background.

IMPORTANCE: The XEN-45 implant, a hydrophilic collagen implant which drains aqueous to the subconjunctival space, has not been investigated in the context of uveitic glaucoma. BACKGROUND: To determine the safety and efficacy of the XEN-45 collagen implant in eyes with uveitic glaucoma. DESIGN: Exploratory prospective case series. PARTICIPANTS: patients with medically uncontrolled uveitic glaucoma. METHODS: Twenty-four consecutive patients (mean age ± standard deviation [SD] = 45.3 ± 18.1 years) were implanted with the XEN-45 implant. MAIN OUTCOME MEASURES: The primary outcome measure was intraocular pressure (IOP) reduction at 12 months as compared to baseline. Secondary outcome measures included ocular hypotensive medication use at 12 months, the requirement for further glaucoma surgery and failure. Intraoperative and postoperative complications were documented. RESULTS: The baseline mean ± SD IOP was 30.5 ± 9.8 mmHg and the mean ± SD number of glaucoma medications required was 3.3 ± 0.8. In 20 eyes (83.3%) in whom conventional glaucoma surgery was originally perceived to be inevitable, further surgery was not required after XEN-45 implantation. The mean IOP was reduced by 60.2% from baseline to 12.2 ± 3.1 mmHg and mean medication usage was reduced to 0.4 ± 0.9 at 12 months (both P < 0.001). One patient had hypotony persisting beyond 2 months that required surgical revision and one patient developed blebitis. The 12-month cumulative Kaplan-Meier survival probability was 79.2%. CONCLUSIONS AND RELEVANCE: The XEN-45 implant is effective for the treatment of patients with medically uncontrolled uveitic glaucoma. Potentially sight-threatening complications, including bleb-related ocular infection and persistent hypotony, may occur.

PURPOSE: To determine whether the second eyes (SE) of patients with bilateral uveitic glaucoma undergoing filtration surgery have more glaucomatous progression in terms of visual acuity, visual field (VF) and optic nerve changes compared to the first eyes (FE). METHODS: This retrospective study analysed data of 60 eyes from 30 patients with bilateral uveitic glaucoma who had undergone glaucoma surgery in both eyes on separate occasions. Humphrey VF progression was assessed using the Progressor software. RESULTS: The pre-operative IOP between the FE (43.1 ± 7.7 mmHg) and SE (40 ± 8.7 mmHg) was not statistically significant (p = 0.15). IOP reduction was greater in the FE (64 %) than SE (59.7 %) post-operatively, but the mean IOP at the final visit in the FE (12.3 ± 3.9 mmHg) and SE (14.5 ± 7 mmHg) was not statistically different (p = 0.2). There was no significant change in mean logMAR readings pre and post-operatively (0.45 ± 0.6 vs 0.37 ± 0.6, p = 0.4) or between the FE and SE. The number of SE with CDR > 0.7 increased by 23 % compared to the FE. From 23 available VFs, five SE (21.7 %) progressed at a median of five locations (range 1-11 points) with a mean local slope reduction of 1.74 ± 0.45 dB/year (range -2.39 to -1.26), whereas only one FE progressed. However, there was no significant difference between mean global rate of progression between the FE (-0.9 ± 1.6 dB/year) and SE (-0.76 ± 2.1 dB/year, p = 0.17) in the Humphrey VF. CONCLUSION: In eyes with bilateral uveitic glaucoma requiring glaucoma surgery, the SEs had more progressed points on VF and glaucomatous disc progression compared to FEs at the final visit.

PURPOSE: To present the long-term results of ab externo trabeculotomy in the management of glaucoma secondary to chronic uveitis. METHODS: In this retrospective single-centre case series, medical records of patients with glaucoma secondary to chronic uveitis, who underwent ab externo trabeculotomy, were evaluated. Two definitions of success were used: intraocular pressure (IOP) 6 ≤ IOP ≤ 21 mmHg (success 1) or 6 ≤ IOP ≤ 21 mmHg and at least 25 % reduction from baseline (success 2). Success was complete when no additional medication was required or qualified when additional medication or cycloablative procedures were required to achieve the specific IOP definition. RESULTS: Twenty-two eyes of 18 patients were included. After 3 years, median IOP decreased from 27 mmHg [range 17-43 mmHg, mean 27.5 mmHg, 95 % confidence interval of the mean (CI) 24.5-30.5 mmHg] to 15 mmHg (range 9-19 mmHg, mean 14.5 mmHg, CI 13-16.1 mmHg). Complete and qualified success 1 was 23 and 45 % after 3 years, respectively. For success 2, the rates were 23 and 32 %, respectively. Hyphema was the most common complication, which resolved completely within 1 month after surgery without further intervention. CONCLUSION: Trabeculotomy ab externo was moderately successful in glaucoma secondary to chronic uveitis after 3 years. No sight-threatening complications were observed during the follow-up period.

PURPOSE: Treatment of secondary glaucoma in uveitis patients is challenging. Owing to the young age of these patients, sufficient lowering of the intraocular pressure (IOP) is essential to prevent progression of visual field loss. However, because of the chronic inflammatory stimulus, filtration surgery has an increased risk of failure, especially in patients who have previously undergone surgery. Therefore, minimally invasive glaucoma surgery is a valuable alternative. METHODS: The clinical records of 24 consecutive patients with uveitic secondary glaucoma who underwent trabeculectomy ab interno with the Trabectome® at the Eye Center of the Albert-Ludwigs University of Freiburg between June 2009 and June 2014 (registered in the Freiburg trabectome database) were retrospectively analyzed. The general baseline information for each patient included age, gender, glaucoma type, ocular medication and current IOP. The postoperative IOP and number of antiglaucomatous medications were recorded at each visit. Statistical analyses were performed using the Kaplan-Meier estimator and Dunnett's t-test. RESULTS: The mean IOP before surgery was 31 ± 6.7 mmHg (median 32 mmHg). Both the IOP and the number of medications significantly decreased over the various follow-up intervals after trabeculectomy ab interno with the Trabectome®. Patients with follow-ups continuing past one year showed an IOP-reduction of approximately 40 % and a medication number reduction from 2 to 0.67. The failure rate (necessitating further glaucoma surgery) was N = 3 (12.5 %) patients.

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.

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.
RESUMO
PURPOSE: To compare outcomes of early aqueous suppression (EAS) and standard therapy (ST) after Ahmed Glaucoma Valve (AGV) implantation for uveitic glaucoma. DESIGN: Retrospective comparative cohort study. PARTICIPANTS: All patients with uveitic glaucoma underwent AGV implantation from January 2010 to October 2020 at Northwestern Medicine. METHODS: Excluding the first postoperative day 1 (POD1), only eyes with IOP 10-15 mmHg at their first visit with IOP ≥ 10 mmHg were included in the main analysis. Early aqueous suppression (EAS) was defined as initiation of ocular hypotensive therapy when IOP was first 10-15 mmHg. Standard therapy was initiation of therapy at any later time. Failure was defined as IOP > 21 mmHg, < 5 mmHg, or < 20% reduction in IOP from baseline after 3 months, for 2 consecutive study visits. Hypotony was defined as IOP ≤ 5 mmHg for ≥ 2 visits. Hypertensive phase was defined as IOP > 21 mmHg for 2 consecutive visits in the first 3 months. MAIN OUTCOME MEASURES: Proportion achieving overall success; incidence of hypotony and hypertensive phase. RESULTS: Twenty-eight eyes of 26 patients were in the EAS group and 20 eyes of 19 patients were in the ST group, with a mean follow-up of 17.7 and 28.2 months, respectively. Baseline IOP was similar in the EAS (31.2 ± 10.1 mmHg) and ST (34.6 ± 12.2 mmHg) groups; P = 0.18. Final IOP was lower in the EAS group (12.9 ± 4.6 mmHg) than the ST group (16.4 ± 5.7 mmHg; P = 0.02) on 2.6 ± 0.9 medications in the EAS group and 1.8 ± 1.5 in the ST group (P = 0.07). Overall success was achieved in 87% of EAS eyes and 74% of ST eyes (P = 0.43). There were no statistically significant differences in the occurrence of additional glaucoma surgery (4% for EAS, 20% for ST; P = 0.11), hypotony (7% for EAS, 0% for ST; P = 0.50), or hypertensive phase (4% for EAS, 21% for ST; P = 0.09). CONCLUSIONS: EAS was associated with a lower final IOP after AGV in uveitic glaucoma eyes; however, more medications were in use at the final visit. No statistically significant differences in overall success or the incidence of adverse events were observed.

PURPOSE: To report a case series of patients with uveitic glaucoma who were treated with micropulse transscleral cyclophotocoagulation (mpCPC). METHODS: This retrospective case series consists of patients from the University of Colorado Sue Anschutz-Rodgers Eye Center from 2015 to 2020 who were diagnosed with uveitic glaucoma. Information collected includes demographic data, type of uveitis, glaucoma severity, and prior glaucoma surgeries. Pre- and postoperative best corrected visual acuity, intraocular pressure (IOP), glaucoma medications, degree of inflammation, and uveitis therapies were included up to 36 months postoperatively. Surgical success was defined as an IOP reduction of 30% with achievement of IOP goal using the same number of glaucoma medications or less at 6 months or 1 year. Uveitis success was defined as the absence of persistent anterior uveitis at 3 months. RESULTS: Six patients and seven eyes with uveitic glaucoma underwent mpCPC. Types of uveitis included idiopathic anterior uveitis, HLA-B27-associated anterior uveitis, varicella zoster virus anterior uveitis, juvenile idiopathic arthritis-associated chronic anterior uveitis, lichen planus-associated intermediate uveitis, and sarcoidosis-associated panuveitis. Two of six eyes (33.3%) at 6 months and three of five eyes (60%) at 1 year achieved surgical success. Around 6 months postoperatively, two out of seven eyes (28.6%) required Ahmed glaucoma valve placement (n = 1) or repeat mpCPC (n = 1). One eye (14.3%) required phacoemulsification with goniotomy followed by an Ahmed glaucoma valve 18 months after mpCPC. There were no cases of persistent anterior uveitis, hypotony, or phthisis after mpCPC in this cohort. CONCLUSIONS: Micropulse transscleral cyclophotocoagulation may safely reduce intraocular pressure in some patients with uveitic glaucoma without exacerbation of intraocular inflammation. Multiple treatments may be required to achieve longer-term success.
