Purpose:
To evaluate vitreoretinal interface anomalies over time in patients diagnosed with toxoplasmosis retinochoroiditis (TRC) and progression of the chronic disease.
Study Design:
Retrospective clinical study.
Methods:
The clinical records of 36 patients with TRC were studied retrospectively. All patients underwent standard ophthalmological examinations and optical coherence tomography (optical coherence tomography: OCT). Vitreoretinal interface changes and retinal layers in the macula and lesion area were evaluated.
Results:
The fovea was involved in 9 (25%) patients. OCT of the scar region showed retinal layer thinning and disorganization in all cases. Complete posterior vitreous detachment (PVD) was detected in 9 (25%) cases, incomplete PVD in 22 (61%) cases and no PVD in 5 (13.8%) cases. In 23 (63%) of the 36 patients with inactive TRC lesions, an epiretinal membrane (ERM) was detected by follow-up OCT, i.e., in 14 (60%) patients with incomplete PVD, 8 (34.7%) with complete PVD, and 1 (4%) with no PVD. Vitreoschisis was found in 5 of 22 patients with incomplete PVD; an ERM developed in 4 of these 5 patients. No ERM developed only in the macula, i.e., independent of the TRC scar region.
Conclusions:
Vitreoretinal interface anomalies are common in patients diagnosed with TRC, including those with incomplete PVD. We observed no progression of vitreoretinal interface anomalies during the follow-up of patients diagnosed with TRC.
