Rhegmatogenous retinal detachment with giant retinal tear masked by dense vitritis in active toxoplasma retinochoroiditis.

A male patient presented with a decreased vision in his right eye since 2 weeks. The best corrected visual acuity was a Snellen's equivalent of 20/200 in the right eye and 20/20 in his left eye. Retinal evaluation of the right eye revealed dense vitritis and a solitary yellowish retinochoroiditis lesion. An ultrasound B scan of the right eye revealed a suspicious high amplitude membranous echo in the posterior vitreous cavity. The patient was diagnosed as having toxoplasma retinochoroiditis and was started on appropriate medical therapy. Within a week of starting treatment, the vision had dropped significantly and a rhegmatogenous retinal detachment with a giant retinal tear was noted. The patient underwent vitreoretinal surgery with silicone oil as endotamponade. The patient did well in the postoperative period maintaining a visual acuity of 20/100 at 4 weeks follow-up and also at 3 months.
