The Success Of Trans-Scleral Diode Laser Cytophotocoagulation As Primary Surgical Procedure For Pediatric Glaucoma: Retrospective Cohort Study

To assess the clinical outcome and safety of Transscleral diode laser cyclophotocoagulation as a primary procedure in managing different types of pediatric glaucoma patients with a follow up of two years under regulated and predetermined set of rules according to guidelines.

Saudi Arabia, Riyadh

A retrospective chart review study in pediatric population with glaucoma who underwent Transscleral diode laser cyclophotocoagulation as a primary procedure with two years of follow-up and no previous glaucoma surgery since 2000 till 2020 at King Khalid Eye Hospital.Definition of Complete success: An IOP of 6 to 21 mmHg without glaucoma medication, Qualified success: IOP of 21 mmHg or lower with a requirement for medication, Failure: IOP >21 mmHg, needing for secondary surgical interventions for glaucoma or having visually devastating complications during follow-up.

A total of 46 patient, commonest diagnosis was congenital glaucoma,History of ocular surgeries was present in 20 patients and history of ocular co-morbidities was present in 25 patients. During a preoperative exam the baseline VA mean was 1.6 with a SD of ±0.7 and Baseline Mean IOP was 32.9mmHg with a SD of ±9.8,Baseline number of medications mean was 2.6 with a SD of ± 1.5. Post-operatively it showed significant change in visual acuity. However, IOP readings post operatively showed drastic changes, its mean was 21.0 mmHg with a SD of ± 11.79 mmHg post operatively.

Trans-Scleral Diode Laser Cyclophotocoagulation as primary surgical procedure for Pediatric Glaucoma does not reveal a good efficacy as there is no significant decrease in IOP.
