[Treatment of vasoproliferative tumors of the retina].

Abstract

Objective: To evaluate the treatment of vasoproliferative tumors of the retina (VPTR). Methods: Retrospective case series study. The clinical data of 20 VPTR patients (20 eyes) were retrospectively analyzed, including 2 eyes only treated by cryotherapy, 1 eye only treated by photocoagulation and 1 eye only treated by ruthenium-106 brachytherapy. The remaining 16 eyes had combined treatment of ruthenium-106 brachytherapy, photodynamic therapy, anti-VEGF therapy, photocoagulation and cryotherapy. Nine eyes were also treated by vitrectomy because of complications such as retinal detachment and vitreous hemorrhage. Results: Single or multiple yellow white or orange red, highly vascular tumor lesions were found in ocular fundi of the 20 eyes. All eyes were accompanied by complications, including intraretinal and subretinal exudations (100%), macular edema (n=19, 95%), epiretinal membrane (n=4, 20%), retinal detachment (n=8, 40%), vitreous hemorrhage (n=6, 30%), abnormal blood vessels (n=16, 80%) and proliferative membrane (n=7, 35%). In the follow-up, the tumor in the eye treated by ruthenium-106 brachytherapy alone was atrophied and the vision improved. Regarding the 2 eyes treated by cryotherapy alone, macular edema and abnormal blood vessels decreased and visual acuity improved in 1 eye, and visual acuity did not change significantly in another eye. More leakages and increased visual acuity were found in the eye treated by photocoagulation alone. Among the 16 eyes treated with combined therapy, 9 eyes had decreased complications and improved visual acuity, 3 eyes did not change significantly, and 2 eyes had increased complications and decreased visual acuity. Conclusions: The conditions of VPTR are complex and difficult to treat. According to the specific conditions, clinicians should choose appropriate treatment methods; different treatment methods can be combined. Laser photocoagulation and cryotherapy may be chosen to treat small tumors complicated with abnormal blood vessels. Ruthenium-106 brachytherapy could treat big tumors complicated with exudative retinal detachment. Vitreous surgery can be used in hemorrhage and tractional retinal detachment. Anti-VEGF therapy is effective in the treatment of macular edema. (Chin J Ophthalmol, 2020, 56:272-278).
