Abstract Details



Purpose:

To report the results of treatments and therapeutic complications of retinal capillary hemangioblastomas (RCH).

Setting:

Retrospective, consecutive case series.

Methods:

Data of 32 patients (37 eyes) with RCH were reviewed for characteristics of RCH, methods of treatment, and visual outcome after treatments.

Results:

Twenty four eyes (65%) of 37 eyes had 20/50 visual acuity or better, 8 eyes (22%) had intermediate vision (20/400−20/50), and 5 eyes (13%) had poor vision (≤20/400). Retinal features at diagnosis of RCH included exudation (60%), macular edema (32%), retinal striae (16%), and tractional retinal detachments (8%). After treatment, 89% of small RCHs (<0.5 mm in size) had regressed, whereas only 69% of large RCHs (>3.0 mm in size) regressed (P = 0.044). Peripheral RCHs showed better response to treatment than juxtapapillary RCHs (P = 0.010). Treatment-related complications occurred in 5 eyes (14%) and one-step combination therapy was applied more frequently in the complication group (P=0.048). Transpupillary thermotherapy (TTT) was used in 40 of 73 RCHs and the regression rate of moderate-sized RCHs was 72.2%.

Conclusions:

Because RCHs grow continuously, small tumors may require early treatment before they grow larger. In larger RCHs, staged treatment could reduce treatment-related complications. As well, TTT may be of use in treating moderate to large-sized RCHs.
