Abstract

Abstract : To report a rare case of pachychoroid neovasculopathy in a patient affected by retinitis pigmentosa describing its features and changes after treatment with bevacizumab documented by swept-source optical coherence angiography. Abstract : Purpose: To report a rare case of pachychoroid neovasculopathy in retinitis pigmentosa (RP) and to describe its features and changes after treatment with bevacizumab as documented by swept-source optical coherence angiography. Methods: A case report of a 69-year-old man with a history of RP who presented at our clinic with an acute decrease in visual acuity (Best corrected visual acuity) in his left eye. Results: Upon the first examination, best-corrected visual acuity in the left eye was 20/50. Fundus examination and fundus autofluorescence showed bilaterally typical features of RP, and enhanced depth imaging–optical coherence tomography revealed a pachychoroid pattern. Fluorescein angiography and indocyanine green angiography suggested the presence of a choroidal neovascularization in the left eye, although no clear evidence of any neovascular network could be identified. Swept-source optical coherence angiography was performed, confirming the presence of a choroidal neovascularization network. The patient was treated with 2 monthly intravitreal injections of bevacizumab. After treatment, BVCA improved to 20/25, and no evidence of the vascular network was detectable on swept-source optical coherence angiography. Conclusion: Our case reports the uncommon association of RP with pachychoroid neovasculopathy. Swept-source optical coherence angiography proved to be a useful imaging technique for the diagnosis and follow-up of this condition. Intravitreal bevacizumab represents an effective treatment for choroidal neovascularization associated with RP.
