Abstract

Purpose: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.Methods: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.Results: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.Conclusion: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.
