Choroidal macrovessel is a rare choroidal vascular abnormality, first reported by Lima et al. A 43-year-old female presented with mild distortion of vision in the left eye. Fundus examination revealed an elevated, hypo-pigmented lesion above the fovea [Figure 1]a. Infrared imaging showed a dilated serpentine choroidal vessel originating at the posterior pole, extending temporally [Figure 1]b. SS-OCT revealed a hyporeflective, oval-shaped choroidal macrovessel indenting overlying retina [Figure 1]c. OCT-angiography through the level of the choroidal vessels showed a signal void area corresponding to the low flow tortuous choroidal vessel [Figure 1]d. These imaging signatures may help differentiate it from other choroidal vascular pathologies such as choroidal neoplasms and parasitic tracks.
|Figure 1: Fundus photography showing an elevated, hypopigmented lesion above the fovea (a) Infrared imaging showed a dilated choroidal vessel running across the posterior pole in a serpentine manner with a fang-like proximal bifurcation (white arrowhead) (b). SS-OCT showed a hyporeflective oval-shaped choroidal macrovessel with a diameter of 405 microns (black arrow) indenting overlying retina with localized RPE alterations. The vessel appeared to arise from Haller's layer (c). OCT-angiography through choroidal vessels showed a signal void area corresponding to low flow tortuous choroidal vessel (d)|
