Clinical, Tomographic, and Angiographic Findings in Patients with Acute Toxoplasmic Retinochoroiditis and Associated Serous Retinal Detachment

Purpose: To describe the clinical, optical coherence tomographic, and angiographic findings in patients with acute toxoplasmic retinochoroiditis (RC) associated with serous retinal detachment (SRD). Methods: The study included 60 eyes with acute toxoplasmic RC. Results: Of 60 eyes, 14 (23.3%) were found to have SRD. The SRD was visible on fundus examination in 6 cases and detectable only by optical coherence tomography (OCT) in the 8 remaining cases. It involved the fovea in 9 eyes. There was evidence of associated choroidal ischemia on fluorescein angiography and indocyanine green angiography in 5 eyes. Findings seen at the acute stage gradually resolved over a period of 2-6 weeks in all patients. Conclusions: SRD, accurately detected by OCT, is a common complication of acute toxoplasmic RC that should be considered as a potential cause of visual loss. Choroidal ischemia might contribute to the development of such complication.
