The outcomes of diode laser transscleral cyclophotocoagulation in refractory primary angle-closure glaucoma in a South Indian population.

BACKGROUND: The surgical intervention of refractory primary angle-closure glaucomas (PACGs) is a big challenge to any ophthalmologist since the efficacy of lens extraction in eyes with a long duration of angle closure is limited. Also, trabeculectomy in such eyes is not without vision-threatening complications. PURPOSE: To evaluate the efficacy and safety of diode laser transscleral cyclophotocoagulation (CPC) in eyes with refractory PACG. METHODS: A retrospective study analyzing all patients who underwent CPC for refractory PACG in the year 2019 was conducted. Out of the 68 patients recruited, 56 PACG patients fulfilled the study criteria. RESULTS: The mean age of the participants was 58.5 years. The mean (standard deviation [SD]) intraocular pressure (IOP) at baseline was 38.91 (14.86) mmHg, and it ranged from 21 to 74 mmHg. Participants' mean (SD) follow-up duration was 11.87 (7.83) months. Almost 90.9% of eyes showed IOP reduction from baseline during the follow-up period. There was also a reduction in the mean antiglaucoma medications (AGM) to 2.67 (1.29) in the final follow-up visit compared to the baseline of 3.30 (0.81). Chronic hypotony was noted in four eyes, out of which phthisis bulbi occurred in one eye. Six eyes underwent additional incisional surgical procedures. CONCLUSION: The outcomes from our study support the role of transscleral diode laser CPC in the interim optimization of IOP in PACG eyes refractory to other modalities. This is emerging as a primary treatment option to optimize IOP to safer limits before any planned incisional procedure. Though complications like chronic hypotony occur as anticipated, vision-threatening complications are rare.

Glaucoma in Uveitic Eyes: Long-Term Clinical Course and Management Measures.

BACKGROUND: The management of glaucoma in uveitis is challenging. A meticulous combination of anti-glaucoma and anti-inflammatory agents is often needed to control the intraocular pressure (IOP) and preserve the visual status in an otherwise blinding disease. AIM: To study the clinical course and management of glaucoma in uveitic eyes. METHODS: A retrospective study analyzing the case records of patients over 12 years, referred for the management of uveitic glaucoma in the last two decades. RESULTS: The analysis of 582 uveitic glaucoma eyes of 389 patients was done, and the mean IOP at baseline was 25.89 (±13.1) mmHg. Non-granulomatous uveitis (102 eyes) was the most common diagnosis. Granulomatous uveitis was the most common diagnosis among the treatment failure eyes and in eyes requiring more than one surgical intervention for glaucoma. CONCLUSION: An appropriate and adequate combination of anti-inflammatory and IOP-lowering therapy will lead to better clinical outcomes.
