[Toxoplasmic retinochoroiditis: relapse vs choroidal neovascular membrane].

CLINICAL CASE: We report four patients with both decreased visual acuity and retinochoroidal lesions compatible with ocular toxoplasmosis in which a diagnosis of active toxoplasmic retinochoroiditis or choroidal neovascular membrane was made based on a specifically designed diagnostic screening.

DISCUSSION: In the context of a compatible clinical picture, with retinochoroidal scars and low grade or absence of inflammation, choroidal neovascular membranes may mimic active toxoplasmic retinochoroiditis and vice-versa. A thorough ophthalmic, serological, and immunological examination (in ocular fluids) may help in the differential diagnosis allowing for proper therapeutic decision-making.
