Abstract
PURPOSE To present the outcomes of Ahmed glaucoma valve (AGV) implantation in uveitic glaucoma (UG) in a tertiary eye center in Riyadh, Saudi Arabia. METHODS A retrospective review of all UG patients who underwent AGV implantation at a single, tertiary care eye center from January 2008 to December 2018. The main outcome measures were change in mean intraocular pressure (IOP), number of antiglaucoma medications, overall success rate in different follow-up periods, complete and qualified success from last follow up, and complications. The success of the treatment was defined as patients achieving intraocular pressure (IOP) levels between 6- and 21-mm Hg with or without additional antiglaucoma medications and/or a minimum of 20% reduction from baseline IOP. RESULTS The study included 74 patients (86 eyes), with a mean follow-up of 4.9 ± 2.9 years. The mean IOP was 32.2 ± 8.5 mmHg at baseline and 16.3 ± 6.6 mmHg at the last follow-up (p < 0.001). The mean number of antiglaucoma medications decreased from 3.5 ± 0.7 preoperatively to 1.3 ± 1.4 at the last follow-up (p < 0.001). Overall survival rates at 1, 3, 5, and 10 years were 96.5%, 92.7%, 91%, and 56.9%, respectively. Complete and qualified success rates were 37.9% and 48.3% at the end of follow up, respectively. The rate of postoperative complications was 56%, of which 18 eyes (20%) required surgical revision. Bivariate Cox proportional hazards regression analysis did not reveal any factors significantly associated with failure. CONCLUSIONS AGV is safe and effective in providing intermediate-term IOP control in UG patients. Complications reported in our cohort were mostly transient and conservatively treated.

Abstract
PURPOSE Uveitis can lead to secondary glaucoma, a condition with challenging management that can carry irreversible visual loss. Filtering surgery has demonstrated a higher failure rate, increased incidence of postoperative complications and reinterventions in uveitic patients. There is no consensus on the optimal surgical approach for uveitic glaucoma (UG) due to limited data comparing various intraocular pressure (IOP)-lowering surgeries. This retrospective cohort aims to assess the clinical outcomes of trabeculectomy (TBT), non-penetrating deep sclerectomy (NPDS), Ex-PRESS shunt and Ahmed glaucoma valve, providing additional insights into the long-term IOP control and safety of filtering surgeries in UG. METHODS The filtering surgery was performed on 32 eyes of 27 UG patients. Complete success was defined as IOP ≤ 18 mmHg or a 30% reduction. Qualified success allowed topical hypotensive treatment. RESULTS Complete success was 40.63% (13/32) at 12 months and 36.67% (11/30) at 36 months. Qualified success was 84.38% (27/32) at 12 months and 63.33% (19/30) at 36 months. In the survival analysis, both NPDS and Ex-PRESS demonstrated decreased failure rates compared to TBT (NPDS vs TBT: HR = 0.20, p = 0.049; Ex-PRESS vs TBT: HR = 0.28, p = 0.13). One or more reinterventions were required in 34.38% (11/32) of the eyes. NPDS had the lowest incidence of hypotony. Secondary cataract was a common complication in all groups. CONCLUSION Various filtering surgeries are safe and effective procedures for lowering IOP and reducing the requirement of topical antihypertensives in UG at 36 months. However, one-third of the patients will require another IOP-lowering procedure.

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.

Abstract
Secondary uveitic glaucoma is a serious sight-threatening complication of intraocular inflammation (uveitis). It develops in approximately 10-20% of patients with uveitis (although this figure may be higher depending on the type of inflammation). It is more commonly associated with chronic forms of uveitis, especially anterior uveitis. Elevation of intraocular pressure (IOP) and the development of secondary glaucoma arise as a direct or indirect consequence of uveitis, and may develop further in association with therapy for intraocular inflammation. Several types of uveitic glaucoma are distinguished according to the mechanism of development: open-angle secondary glaucoma (including steroid-induced secondary glaucoma), angle-closure secondary glaucoma, and a combination of both. It is necessary to determine the pathogenesis of uveitis and target the treatment of the inflammatory process according to it. Subsequently, it is necessary to determine the type of secondary glaucoma, which influences the choice of therapy. Compensation for IOP should be achieved as quickly as possible, before irreversible damage to the optic nerve and visual field occurs. In the first instance, we choose conservative pharmacological therapy. However, this therapy fails more often in secondary uveitic glaucoma than in primary open-angle glaucoma. For this reason, surgical or laser therapy is necessary for refractory glaucoma. Trabeculectomy remains the gold standard in surgical therapy for secondary uveitic glaucoma, but other surgical techniques can also be used (Ahmed drainage implants, goniotomy in the paediatric population, surgical iridectomy, and synechiae for angle closure etc.). The choice of method is individualised according to the clinical findings of the patient and previous ocular procedures. However, the main factor influencing the success and efficacy of filtration surgery is adequate therapy and control of the intraocular inflammatory process.

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 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
BACKGROUND/AIM The aim of the study was to examine the effect of the COVID-19 pandemic on glaucoma surgical practices within the UK. METHODS A cross-sectional online survey was distributed to all consultant glaucoma specialists who are on the UK and Eire Glaucoma Society contact list. Participants were asked specific questions regarding preferences in glaucoma surgical practices and whether these had changed subsequent to the onset of the COVID-19 pandemic. RESULTS Trabeculectomy was the procedure of choice for 61 (87%) glaucoma specialists. A total of 51 (73%) respondents reported performing minimally invasive glaucoma surgery (MIGS) procedures before the COVID-19 pandemic. The most commonly performed MIGS procedure was the iStent inject (51%), followed by XEN 45 (36%) and Preserflo (17%). Forty-three (61%) respondents reported modifying their glaucoma surgery practice subsequent to the onset of the COVID-19 pandemic. Of the glaucoma specialists who modified their surgical practices, 21 (43%) specifically reduced the number of trabeculectomies performed. In combination, diode laser (both micropulse and conventional trans-scleral cyclodiode) was the most common alternative procedure. Glaucoma drainage devices, deep sclerectomy and Preserflo were also commonly chosen alternatives. CONCLUSION Although trabeculectomy remains the most commonly performed established glaucoma surgery, it is being performed with reduced frequency during the COVID-19 pandemic due to the number of postoperative visits and procedures required. Alternatives such as conventional and micropulse diode laser, glaucoma drainage devices, deep sclerectomy and Preserflo appear to be the favoured alternative procedures.

Abstract
Human T-cell lymphotropic virus type 1 (HTLV-1) was the first retrovirus identified as the causative agent of human diseases, such as adult T-cell leukemia, HTLV-1-associated myelopathy, and HTLV-1 uveitis (HU). HU is one of the most frequent ocular inflammatory diseases in endemic areas, which has raised considerable public health concerns. Approximately 30% of HU patients develop secondary glaucoma, which is higher than the general uveitis incidence. We therefore investigated the mechanism underlying the high incidence of glaucoma secondary to HU in vitro. After contact with HTLV-1-producing T cells (MT-2), human trabecular meshwork cells (HTMCs) were infected. The infected cells increased in number, and nuclear factor (NF)-κB expression was activated. Contact between MT-2 cells and HTMCs resulted in significantly upregulated production of inflammatory cytokines, such as IL-6, and chemokines, such as CXCL10, CCL2, and CXCL-8. These findings indicate that the mechanism underlying secondary glaucoma in HU may involve proliferation of trabecular meshwork tissue after contact with HTLV-1-infected cells, resulting in decreased aqueous humor outflow. Upregulated production of inflammatory cytokines and chemokines simultaneously disrupts the normal trabecular meshwork function. This mechanism presumably leads to increased intraocular pressure, eventually resulting in secondary glaucoma.

Abstract
Aim and objective This study aimed to evaluate the performance of and indication for different surgical techniques in the management of uveitic glaucoma (UG). Materials and methods A retrospective audit of records of all patients with UG who underwent ≥1 glaucoma surgery, between January 2007 and December 2016. The main outcomes were intraocular pressure (IOP) and the need for antihypertensive medication at each follow-up visit. The total number of surgical interventions needed to control IOP was recorded. Postoperative interventions and complications were analyzed. Results Forty eyes from 34 patients were assessed. Overall, baseline IOP was 30.7 ± 8.2 mm Hg, and postoperative mean IOP at the last visit was 16.4 ± 2.0 mm Hg, with a mean follow-up of 28 months. Antihypertensive medications were reduced from 2.8 ± 0.8 to 0.8 ± 1.2. During the follow-up, 61.8% of the eyes required only one glaucoma surgery. There was no correlation between the location of uveitis and the total number of glaucoma surgeries required. The greatest IOP reductions were in cases treated with non-penetrating deep sclerectomy (21%), Ahmed valve (23%), and cyclophotocoagulation (CPC) (51%); in cases where an Ahmed implant was the first surgical option, a 43% reduction was achieved. Conclusion Filtering procedures, glaucoma drainage devices, and CPC are all good options for IOP control in UG, but all are prone to failure over time. With respect to IOP reduction, the safety profile, and postoperative care, Ahmed implants and CPC might be the best first surgical option. Clinical significance The article highlights the versatility of the surgical techniques required to treat UG, which is one of the most difficult types of glaucoma to manage.

Abstract
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.

Abstract
PRECIS A modified CO2 laser-assisted sclerectomy surgery (CLASS) based on the characteristics of Chinese eyeball was carried out in Chinese patient and was confirmed to be effective and safe during long-term follow-up. PURPOSE The purpose of this study was to study the long-term efficacy and safety of modified CLASS in Chinese patients with primary open-angle and pseudoexfoliative glaucoma. METHODS We enrolled 25 medically uncontrolled primary open-angle and pseudoexfoliative glaucoma patients in this prospective, interventional case series. A combination of modified CLASS and preoperative laser iris management was administered to 29 eyes. Visual acuity, intraocular pressure (IOP), slit-lamp examinations, visual field, and gonioscopy were carried out at baseline and until 24 months postoperatively. Ultrasound biomicroscopy examinations were repeated at 3, 12, and 24 months postsurgically. RESULTS Mean patient age was 53.92±12.08 years. Mean preoperative IOP was 30.66±10.41 mm Hg; and mean postoperative IOP was 8.17±3.76, and 13.25±2.73, 13.76±2.50, and 13.76±2.50 mm Hg at 1 day, and 6, 12, and 24 months, respectively. Proportional changes in IOP from baseline at 6, 12, and 24 months was 58.33%, 56.25%, and 58.97% (P<0.001), respectively. Complete postoperative success rates at 12 and 24 months were 62.07% and 48.28%. Qualified success rates at 12 and 24 months postoperatively were both 89.66%. Number of medications administered per patient reduced from 3 at baseline to 0 at 12 and 24 months (P<0.0001). Two patients demonstrated severe peripheral anterior synechiae (6.90%). Ultrasound biomicroscopy examination revealed a severe scleral lake diminution in 1 patient (3.40%) at 12 months and 2 patients (6.90%) at 24 months. CONCLUSION Combination of modified CLASS and preventive laser iris management was effective and safe in the long-term treatment of primary open-angle glaucoma patients.

Abstract
The chapter is a review enclosed in the volume "Glaucoma: A pancitopatia of the retina and beyond." No cure exists for glaucoma. Knowledge on the molecular and cellular alterations underlying glaucoma neurodegeneration (GL-ND) includes innovative and path-breaking research on neuroinflammation and neuroprotection. A series of events involving immune response (IR), oxidative stress and gene expression are occurring during the glaucoma course. Uveitic glaucoma (UG) is a prevalent acute/chronic complication, in the setting of chronic anterior chamber inflammation. Managing the disease requires a team approach to guarantee better results for eyes and vision. Advances in biomedicine/biotechnology are driving a tremendous revolution in ophthalmology and ophthalmic research. New diagnostic and imaging modalities, constantly refined, enable outstanding criteria for delimiting glaucomatous neurodegeneration. Moreover, biotherapies that may modulate or inhibit the IR must be considered among the first-line for glaucoma neuroprotection. This review offers the readers useful and practical information on the latest updates in this regard.

Ther Adv Ophthalmol 2019; 11:2515841419869761.

Abstract
Background: Deep sclerectomy offers the potential advantage of less postoperative inflammation and better survival in Fuchs’ patients. The aim of this study was to compare survival and safety profiles of Fuchs’ heterochromic uveitis patients undergoing trabeculectomy or deep sclerectomy. Methods: A retrospective study was conducted of two separate cohorts who had undergone either trabeculectomy or deep sclerectomy. Patient demographics, best-corrected visual acuity, intraocular pressure, antimetabolite used, postoperative complications and subsequent procedures were analysed. Results: In total, 13 trabeculectomy patients and 14 deep sclerectomy patients were included. Mean preoperative intraocular pressure was similar at 30.1 mmHg in the trabeculectomy group and 35.9 mmHg in the deep sclerectomy group, with no significant difference between the two (p = 0.22). Kaplan–Meier survival outcomes for success at <22 mmHg and <19 mmHg showed no significant differences between the groups and this was also the case for intraocular pressure at 3 years (analysis of variance; p = 0.47). Conclusion: Both procedures appear to have similar efficacy and safety profiles, suggesting that both are effective.

Abstract
Ocular hypotony is an infrequent, yet potentially vision-threatening, entity. The list of differential causes is extensive, involving any condition that may compromise aqueous humor dynamics or the integrity of the globe and sometimes following medical treatments or procedures. Depending on the cause and the clinical impact, treatment options aim to correct the underlying pathology and to reestablish anatomical integrity, as well as visual function. We review the pathophysiology, clinical presentation, different causes, and associated therapeutic options of ocular hypotony.

[PMID: 30310971 PMCID: PMC6323086 DOI: 10.1007/s00417-018-4156-9] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2018] [Revised: 09/24/2018] [Accepted: 10/02/2018] [Indexed: 01/20/2023] Open
Abstract
Purpose To assess the efficacy of glaucoma drainage devices (GDD) in uveitic glaucoma and non-uveitic glaucoma, and to perform a meta-analysis of previously published results to compare with our data. Methods Retrospective case-control study, in which all eyes that underwent GDD surgery were included from 2015 onwards. Cases were defined as patients with uveitic glaucoma. Patients with non-uveitic glaucoma served as controls. To compare our results, a review of the literature was performed using PubMed database. Results A total of 99 eyes were included (38 with uveitic glaucoma). The preoperative IOP was 25.9 ± 7.7 mmHg and 27.9 ± 9.6 mmHg for patients with and without uveitis (p = 0.277). No significant differences were found between patients with and without uveitis in the final IOP or reduction in IOP (44.9% vs. 42.8%, respectively). Within the first year after surgery, 13.2% of cases developed macular edema (vs. 6.6%; p = 0.267) and 15.8% a transient hypotony (vs. 8.2%; p = 0.242). A meta-analysis of 24 studies showed a postoperative weighted mean difference of − 17.8 mmHg and 2.2 lower number of IOP-lowering medications in uveitic glaucoma (compared to − 13.2 mmHg and 3.5 in the current study, respectively). Conclusion GDD surgery in patients with uveitis has a similar effect on IOP as in patients without uveitis. The risks of developing macular edema and hypotony were slightly higher in patients with uveitis, but the results were not statistically significant. These findings are in line with previous reports, though data on the efficacy of GDD surgery and macular edema in uveitic glaucoma is scarce.
