Karacorlu M, et al. - Patients who underwent endoresection of complex retinal capillary hemangioblastoma (RCH) were examined for the anatomical and functional outcomes. Providing high anatomical success and stable or even improved visual acuity, acceptable rates of disease- and treatment-related complications, and minimal need for retreatment, combined pars plana vitrectomy, endodiathermy of feeding and draining vessels, endoresection of RCH, and silicone oil injection may be an effective treatment option for complex RCH.

• Researchers retrospectively examined case series of 12 patients (13 eyes), all treated with pars plana vitrectomy, endodiathermy of feeding and draining vessels, endoresection of RCH and silicone oil injection.

• Data showed that 32.5 ± 15.9 years was the mean age at the time of surgery, and the mean follow-up duration after initial surgery was 50.5 ± 49.4 months.
• Surgery was indicated for RCH with associated complications such as tractional retinal detachment in five eyes (38%), exudative retinal detachment in four eyes (31%), and combination of tractional retinal detachment and exudative retinal detachment in four eyes (31%).
• The following were dimensions of the resected RCHs: >3.0 mm in seven eyes (54%), >3.5 mm in three eyes (23%), and >4.0 mm in three eyes (23%).
• It was noted that no tumor was located closer than 10 mm to the optic nerve or fovea.
• Findings demonstrated that anatomical success after initial surgery was 92%.
• Owing to recurrent RD, a second vitreoretinal procedure was performed on one eye.
• Researchers found that the mean preoperative Snellen visual acuity was 20/303 and the mean Snellen visual acuity at the final visit was 20/73.
• At the final visit, improved visual acuity was observed in seven eyes (54%), and six eyes (46%) were stable.
• Recurrent proliferative vitreoretinopathy in one eye (8%), transient ocular hypertension requiring topical antiglaucoma treatment in four eyes (31%) were documented as short-term complications.
• Progression of cataract in seven eyes (54%) was reported as long-term complication.
