BACKGROUND: Despite many recent developments, preference in the choice of surgical treatment of uncontrolled intraocular pressure (IOP) remains a challenge.
OBJECTIVE: This study compares the clinical efficacy and safety of endoscopic cyclophotocoagulation (ECP) to alternative surgical procedures, for all types of glaucoma.
METHODS: The methodology adheres to the preferred reporting items for systematic reviews and meta-analyses guidelines for systematic review reporting. Studies reporting ECP and alternative surgeries in treating refractory glaucoma, neovascular glaucoma, aphakic glaucoma, filtering surgical failure-induced glaucoma, congenital or juvenile glaucoma, and secondary glaucoma such as uveitis glaucoma, traumatic glaucoma, secondary glaucoma postcorneal transplantation, etc. were included. The efficacy was evaluated from the number of IOP-lowering drugs, and mean change in pre- and post-IOP were the outcomes assessed in ECP and non-ECP groups in this review. Evaluations of the postoperative complications revealed the safety assessment of the procedure.
RESULTS: In total, 11 relevant studies were selected in this study with a total of 5418 eyes, including 763 eyes in the ECP group and 4655 in the non-ECP group. This review observed that both ECP and non-ECP procedures had been successful in reducing postoperative IOP.
CONCLUSIONS: It can be deduced from this review, that all types of glaucoma can be treated efficiently with significantly higher success rates with ECP and ECP demonstrates lowest postoperative complications when compared to non ECP procedures. This review provides updated scientific evidence which caters to support clinical decisions for surgical treatment of glaucoma.

Viral keratouveitis (VKU) could be visually debilitating owing to the intraocular inflammation causing collateral damage to the cornea and secondary elevation of intraocular pressure (IOP). In this retrospective, single-center, observational study, we analyze the clinical features and management options for VKU, with a brief review on incidence of glaucoma and its treatment outcomes. We reviewed the outpatient records at our tertiary hospital from 2015 to 2020 and found 53 eyes of 55 patients diagnosed as VKU. The main outcome measures were incidence of clinical signs, elevated IOP and glaucoma, and treatment modalities used. Sixty-four percent were males with a mean age of onset being 45.4 years. Eighty percent of the eyes were clinically diagnosed to have herpes simplex virus (HSV), 16% herpes zoster virus (HZV) and 4% cytomegalovirus (CMV). Ocular presentations most commonly noted were keratic precipitates (70.4%), corneal edema (66.7%). Associated elevation of IOP was seen in 24 eyes (44%), while glaucomatous damage was seen in 20% of the eyes. Those with fewer uveitic episodes (less than two), as opposed to those having more than two episodes (p < 0.09) posed a lesser risk of developing glaucoma. Almost all were treated with topical steroids and oral acyclovir. The need for glaucoma surgery, in our study, was only 7.2%. Majority of patients with glaucoma, as compared to those without, appeared to have a higher number of IOP spikes and uveitic episodes. CMV-associated eyes had higher risk of developing glaucoma and were more intractable, requiring more intense treatment strategies. This review of the clinical profile of an exclusive South Indian cohort of VKU with an attempt to understand the differences in presentation between the herpetic and CMV groups and its implication from a glaucoma perspective makes this study distinctive.

Glaucoma is a disorder of all species due to a rise of intraocular pressure (IOP) beyond which is compatible with ganglion cell and axon function, often resulting in optic nerve degeneration and irreversible blindness. Glaucoma treatment with surgical intervention aimed at either reducing aqueous production, or increasing or altering aqueous outflow has evolved over preceding decades, but there remains no cure. The present article is intended to provide a concise review of glaucoma surgical therapies in veterinary ophthalmology.
