Macular sequelae in vasoproliferative tumors: results of surgical approach

Abstract

The purpose of this study is to report the clinical manifestations and treatment outcomes in three patients diagnosed with vasoproliferative tumors (VPTs). A retrospective, single-center case series was conducted, and retinal findings from three cases were documented by clinical examination and multimodal imaging. Three patients presented with an elevated, yellow-white retinal lesion located at the peripheral retina and extensive retinal exudation. All three patients were closely monitored, and tumor-associated features included lipid exudates, cystoid macular edema (CMO), pre-retinal fibrosis and epi-retinal membrane (ERM). Clinical management relied on observation, cryotherapy, laser photocoagulation, intravitreal steroids and anti-vascular endothelial growth factor (anti-VEGF) treatment. Despite different clinical courses, two patients underwent vitreo-retinal surgery to address VPT-related complications of macular hole and vitreo-macular traction, whereas a patient underwent phacoemulsification to treat steroid-induced cataract. VPTs are uncommon benign vascular tumors and usually located at the infero-temporal peripheral retina. Close observation and early diagnosis of VPTs are of great importance in preventing vision-threatening complications and ensuring the best final visual outcome. The optimal treatment has yet to be defined due to lack of multi-center clinical studies. Despite the availability of less invasive therapeutic interventions, however, our case series show that pars plana vitrectomy is sometimes the most appropriate choice to restore visual acuity.
