OCT-angiography for the diagnosis of radiation maculopathy in patients treated with proton beam therapy
Purpose: Radiation maculopathy (RM) is the leading cause of visual acuity (VA) loss after proton beam therapy (PBT) of choroidal melanoma. The aim of this study was to assess the value of optical coherence tomography-angiography (OCT-A) for the diagnosis of RM in patients with choroidal melanoma treated with PBT. Materials & methods: This 2-year prospective, descriptive, single-center study included patients treated with PBT for choroidal melanoma. VA measurement, retinography, OCT and OCT-A were performed. Vascular density (VD) in the superficial capillary plexus (SCP), peri-foveal anastomotic ring changes and foveal avascular zone (FAZ) enlargement were studied. Results: Nineteen patients were included in ...
