Outcome of Transscleral Cyclophotocoagulation in Refractory Glaucoma at a Tertiary Eye Hospital in India

Abstract

Background: Transscleral cyclophotocoagulation (TSCPC) is a cyclodestructive procedure used to control

elevated intra ocular pressure(IOP) in refractory glaucoma. We studied the efficacy and safety of TSCPC in

refractory glaucoma at our hospital.

Method: Data was collected retrospectively from patients who underwent TSCPC over a two year period.

Primary outcome measure was success in terms of IOP reduction and the secondary outcome measures were

relief of symptoms and incidence of complications.

Results: 27 of 42 patients who underwent TSCPC were included for analysis which included 16 men and 11

women with mean age 61.8±13years and visual acuity ranging from 6/24 to no perception of light.

Mean IOP decreased from 46.0±8.6 mmHg(range: 26-58 mmHg) pre-procedure to 16.7±13.4 mmHg(p<0.001)

at last follow-up. Complete success was achieved in 22.2%, qualified success in 18.5%, 29.6% eyes had

hypotony and 29.6% failed. Mean glaucoma medications decreased from 3.2±1.3 to 0.9±1.2(p<0.001).

Patients were asymptomatic; complications were phthisis and vitreous hemorrhage which resolved (one

case each).

Conclusion: TSCPC is a safe and effective method of controlling IOP in refractory glaucoma. It may not be

restricted to eyes with poor vision potential and a pain-free patient is often the end result.
