PURPOSE: To study the outcomes of diode laser transscleral cyclophotocoagulation (TSCPC) with trans-corneal transillumination using a novel low-cost torchlight method in refractory glaucoma. METHODS AND ANALYSIS: This prospective interventional study included patients with refractory glaucoma who underwent TSCPC with trans-corneal transillumination (TSCPC-TI) using a novel low-cost torchlight method. Patients completing a minimum 6-month follow-up were analyzed. They were compared to a historical control group of patients who underwent TSCPC without transillumination (TSCPC-No TI) at 6-month follow-up period. We analyzed the mean laser energy delivered, post-laser intraocular pressure (IOP) reduction, number of antiglaucoma medications (AGM), the requirement of retreatment and complications of the procedure in both groups. RESULTS: 32 eyes of 29 patients comprised the TSCPC-TI group and were compared with 39 eyes of 37 patients in the TSCPC-No TI group. The TSCPC-TI group required lower energy than the TSCPC-No TI group (46.15 ± 22.8 Vs 80.65 ± 56.1 J < 0.001). At 6-month follow-up, the TSCPC-TI group required lesser AGM for IOP control (2.33 ± 1.02 vs 3.02 ± 1.32 = 0.01). There was a significantly reduced dependence of oral acetazolamide in the TSCPC-TI group at 6 months follow-up (15.6% vs 41% = 0.03%). The success and response rates were 71.8% Vs 23.1%; < 0.0001 and 87.5% Vs 51.2%; = 0.001 significantly high in the TSCPC-TI group. The TSCPC-No TI group had a significantly high failure rate (12.5% Vs 48.2% = 0.001). Hypotony ( = 1) and phthisis ( = 2) were noted TSCPC-No TI group. CONCLUSIONS: TSCPC with transillumination with a low-cost torchlight resulted in a more efficient and effective cycloablation than TSCPC without transillumination.
