OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IMAGING OF CHOROIDAL NEOVASCULARIZATION SECONDARY TO CHOROIDAL RUPTURE TREATED BY INTRAVITREAL RANIBIZUMAB

Abstract

To describe optical coherence tomography angiography findings at baseline and during the follow-up of choroidal neovascularization secondary to choroidal rupture (CR) in a patient with kidney transplant treated by a single intravitreal injection of ranibizumab. The clinical course, conventional multimodal imaging findings including ultra-widefield fundus color photography and fundus autofluorescence (Optos California, Marlborough, MA), spectral-domain optical coherence tomography (SD-OCT Spectralis; Heidelberg Engineering, Heidelberg, Germany), fluorescein angiography (FA; Heidelberg Engineering, Heidelberg, Germany), indocyanine green angiography ,and optical coherence tomography angiography (Plex-Elite, Carl Zeiss Meditec, Inc, Dublin, CA) findings at baseline and during the follow-up of a patient with choroidal neovascularization secondary to CR. A 19-year-old young man with a history of blunt trauma presented with acute visual decline of the right eye. He had a systemic history of kidney transplant. His best-corrected visual acuity was 20/200 in the right eye and 20/20 in the left eye at baseline. Funduscopic examination and ultra-widefield fundus autofluorescence imaging revealed a double vertical macular lesion corresponding to a CR in the right eye. Spectral-domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography revealed active Type 2 choroidal neovascularization secondary to the CR. Optical coherence tomography angiography showed a high-flow neovascular network consistent with conventional multimodal imaging. One month after intravitreal injection of ranibizumab, bestcorrected visual acuity was 20/100, optical coherence tomography angiography showed a contraction and remodeling of the neovascular flow, and exudative signs disappeared on multimodal imaging. No side effect was detected. Optical coherence tomography angiography is able to detect choroidal neovascularization secondary to CR at baseline and during the follow-up after a single intravitreal injection of ranibizumab. Ranibizumab was effective in the treatment of this sight-threatening lesion in a patient with a history of kidney transplant.
