Clinical course of bilateral endogenous endophthalmitis in 5-year-old female Birman cat evaluated by slit-lamp biomicroscopic examination, Madrid, Spain. A) Digital photograph of both eyes demonstrating bilateral uveitis at 5.5 months after initial visit to clinic. B) Slit-lamp biomicroscopic image (original magnification ×10) of the left eye, demonstrating a marked flare (yellow arrows) at 6.5 months after initial clinical signs. C, D) At 16.5 months, the right eye (C) (original magnification ×10) and left eye (D) (original magnification ×16) were imaged by slit-lamp biomicroscopic examination, revealing corneal endothelial macrodeposits of undefined origin, presumed to be the result of Prototheca spp. invasion. Scale bars indicate 5 mm.
