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