This study evaluates the retinal and vascular features in patients with radiation maculopathy under the effects of Ranibizumab intravitreal injections using optical coherence tomography and optical coherence tomography angiography.

The radiation maculopathy is a consequence of radiotherapy for treatment of choroidal melanoma. The radiation maculopathy is characterized by the compromission of the macular microvasculature that can lead to the leakage, lipid exudates, hemorrhages, teleangiectasie, macular edema, non perfusion areas with consequent significant impaiment of visual acuity.

Ranibizumab is a vascular endothelial growth factor antagonist and it represents an efficacy treatment acting on vascular hyperpermeability. The optical coherence tomography and optical coherence tomography angiography represent novel and non-invasive diagnostic techniques that allow a detailed analysis of retinal and vascular features. The study evaluates the changes in optical coherence tomography and optical coherence tomography angiography parameters at baseline and after intravitreal injections of Ranibizumab at the last follow up to one year in patients affected by radiation maculopathy.

Inclusion Criteria:

• age older than 40 years
• diagnosis of radiation maculopathy
• treatment-naïve with Ranibizumab
• absence of other vitreoretinal and vascular retinal diseases

Exclusion Criteria:

• age younger than 40 years
• No diagnosis of radiation maculopathy
• previous treatments with Ranibizumab
• presence of vitreoretinal and vascular retinal diseases

The participans were older than 40 years with diagnosis of radiation maculopathy. They did not present other ophthalmological diseases.
