Purpose : To compare outcomes of transscleral diode cyclophotocoagulation using short (SD) versus longer duration (LD) treatment.

Methods : Data were collected retrospectively on patients with glaucoma who underwent cyclophotocoagulation with LD (4000 ms) treatment with variable power ≤1000 mW versus SD using 1500 ms with variable power ≤2000 mW. The outcome measures included: intraocular pressure (IOP) at 12 months, decrease in number of anti-glaucoma medications, complications and visual acuity (VA) at the final follow-up visit

Results : There were 71 patients and 70 patients in the SD and LD groups, respectively. The mean IOP ±SD pretreatment baseline was 36±10 versus 33±10 mmHg for LD and SD groups, respectively (p>0.05). At one year postoperatively, the IOP decreased significantly in both groups (16.7 mmHg versus 17.4 mmHg SD and LD, respectively; p<0.0001). This decrease in IOP was comparable between groups (p=0.5). The average number of IOP lowering medications were 2.5 and 2.9 at baseline in the SD and LD groups respectively and decreased to 1.3 in both groups (p=0.83). The mean LogMAR VA decreased significantly from 2.03 at baseline to 2.3 at 1 year (p≤0.001) in the LD group and, 1.87 to 1.96 in the SD group (p=0.276), This change was comparable (0.19; p=0.075) between the two groups. Complications were also comparable

Conclusions : Both LD and SD burns during cyclophotocoagulation effectively lowered IOP at 1 year. Neither treatment resulted in a greater reduction of IOP. LD treatment appeared to result in a decrease in VA and greater postoperative inflammation
