| Title | Unilateral diffuse retinal bleeding and explosive choroidal neovascularization after coughing in a patient with angioid streaks | 
| Purpose | Presentation of a peculiar case of a unilateral retinal bleeding and explosive choroidal neovascularization in a patient with angioid streaks, its work-up and its treatment. | 
| Methods | Multimodal imaging (fundus photography, OCT, angio-OCT and fluorescein angiography) was performed to assess a 39-year-old man with angioid streaks who complained of distortion of vision and a decrease in visual acuity in the right eye 2 weeks after an episode of cough. An explanation for the unilateral presentation was assessed by looking for signs of fragility of the right eye compared to the left eye. | 
| Results | Fundus exam: on the right eye, multiple retinal fusiform hemorrhages in all 4 quadrants that were absent on the left eye. OCT: signs of 3 infiltratives zones of perifoveolar suberetinal choroidal neovascularization with serous retinal detachment in the right eye and physiological foveolar depression in the left eye. Angio-OCT: non-contributive. Fluorescein angiography: right eye: multiple perifoveolar staining of neovascular choroidal lesions. Concerning signs of fragility: the right eye is surprisingly less myopic (25.88 mm) and presumed less fragile than the left eye (26.21 mm) and the involvement of the angioid streaks seems similar and symmetric. | 
| Conclusion | Complicated angioid streaks in the right eye with type 2 neovascularization of explosive onset and retinal hemorrhages on Valsalva effort. We performed intravitreal injections of anti-VEGF ranibizumab and planned follow-up consultations. No reason was yet found for the unilaterality of the ocular involvement. A vascular assessment could be considered in order to objectify a potential asymmetry explaining the unilaterality of the ocular involvement. |
