Purpose:
To report a patient with retinal capillary hemangioblastomas associated with Von Hippel-Lindau syndrome who achieved long-term visual improvement with single intravitreal bevacizumab injection followed by laser photocoagulation.
Methods:
Intravitreal bevacizumab injection was performed in a 17-year-old girl with bilateral multiple retinal capillary hemangioblastomas. Laser photocoagulation was then performed to augment the initial response to bevacizumab. The visual acuity, fundus photography, fundus fluorescein angiography, and ocular coherence tomography were obtained at each visit. The patient was followed-up for 3 years.
Results:
Two weeks after injection, the macular edema and exudation significantly decreased with an improvement in the visual acuity. Laser photocoagulation performed 2 weeks after the intravitreal bevacizumab injection provided further regression of exudation and scarring of the hemangioblastomas. No further intervention was required, and the visual acuity returned to baseline at the third year of follow-up.
Conclusion:
Combined intravitreal bevacizumab with laser photocoagulation is a viable option in retinal capillary hemangioblastomas associated with Von Hippel-Lindau syndrome.
