ABSTRACT

Arterial obstructive disease of the eye is frequently encountered in clinical practice. It usually occurs suddenly and presents dramatically, but there is also a chronic form of presentation that is less frequently appreciated.
In one large series of retinal artery obstructions, 38% involves one of the branch retinal arteries and although rarely, an obstruction can developed when a vessel passes through a focal toxoplasmic retinochoroidal lesion.
We report a case of a 40 year-old woman who had acute loss of vision in the left eye. Ocular biomicroscopic examination showed inflammatory cells were present in the posterior vitreous of her right eye. In the distribution of the superotemporal artery the retina was white from cloudy swelling, characteristic of branch retinal artery occlusion at the site of an active retinochoroidal inflammatory lesion. Fluorescein angiography confirmed the active retinochoroidal inflammatory lesion.
She was treated with oral sulfametoxasol/trimetoprim, pirimetamine and oral prednisone resulting in the resolution of the inflammatory lesion.
This subject had an acute focal retinochoroidal inflammatory lesion characteristic of reactivated toxoplasmosis infection and was associated with branch retinal artery occlusion, which can occur, although rarely, when a vessel passes through an acute toxoplasmic lesion.
