Seventy-three tumors were identified in the 37 eyes. Seven (9.6%) were identified in the juxtapapillary area, and 66 (90.4%) were identified in the peripheral area.
Small tumors less than 0.5 mm underwent laser photocoagulation. Moderate-size tumors that were 0.5 mm to 3 mm underwent transpupillary thermotherapy. Large tumors greater than 3 mm underwent combined transpupillary thermotherapy and cryotherapy.
Mean follow-up was 33.6 months.
After treatment, 90% of small tumors and 66.7% of large tumors regressed; the between-group difference was statistically significant (P = .044).
Peripheral tumors responded significantly better to treatment than juxtapapillary tumors (P = .010).
Size and location of tumors were the only factors that significantly affected tumor regression.
Five eyes (14%) experienced treatment-related complications; one-step combination therapy was used more frequently in eyes with complications (P= .048).
Tumors of patients with good baseline best corrected visual acuity of 20/50 or better typically showed greater regression than those of patients with poor baseline BCVA of 20/400 or worse, but the difference was not significant.
