a Fundus photography of both eyes showed scattered dot and blot hemorrhages with some cotton-wool spots in the retina. Arterial narrowing was obvious and normal foveal reflex was disrupted in the left macula. b Fluorescein angiography of both eyes showed multiple diffused capillary non-perfusion areas in the peripheral retina. Also in the left eye, an area of fluorescein leakage due to large retinal neovascularization was noted on the superior arcade.

Fundus examination of both eyes showed scattered dot and blot hemorrhages with some cotton-wool spots in the retina at mid-periphery, arterial narrowing, and reduced foveal reflex in the left macula (Fig. 1a). Also in the left eye, an area of fluorescein leakage due to large retinal neovascularization on the superior arcade was noted (Fig. 1b).
Spectral-domain optical coherence tomography of both eyes. In the right eye, normal retinal structures were revealed, but in the left eye, dome-shaped cystic space (white star) containing marginal septa (arrows) which had split the MZ from EZ was detected. Choroidal congestion and RPE corrugation were also evident.

The OCT of the left eye showed a large, dome-shaped cystic space with marginal septa, splitting the MZ and consistent with the BLD phenotype (Fig. 2).
Optical coherence tomography of the left eye. a Two weeks after intravitreal bevacizumab injection, central retinal thickness was significantly decreased. b 4 weeks after injection, complete resolution of bacillary detachment and RPE corrugation was occurred.

After 4 weeks, BCVA improved to 20/25 with complete resolution of BLD (Fig. 3).
