“…A more flattened preretinal oval lesion that appears to follow a similar pattern of resolution with treatment has been noted, although previous authors do not specify the vitrectomy status of these patients, which may account for the difference in shape. 3 The linear improvement in our case similar to other cases was likely a result of the treatment of the toxoplasmosis and associated inflammation.…”

SummaryWe report a new clinical sign of vitreous inflammation in patients with posterior uveitis: spectral-domain optical coherence tomography identified stalagmite-like, discrete, diffusely distributed, hyperreflective, preretinal deposits in previously vitrectomized eyes of 2 patients during flares of posterior uveitis. The extent of the deposits correlated with disease activity. The underlying primary diseases encountered were necrotizing retinochoroiditis secondary to toxoplasmosis and primary central nervous system lymphoma.

“…The density of the vitreous cells graded by ophthalmoscopy and punctuate spots on SOCT scans were consistent. In the literature, there are reports that show punctuate spots within the retina [9,10]. In our cases, we did not find any deposit within the retina.…”

Introduction: The aim of this study was to report the causes of visual impairment in patients with the classic clinical presentation of ocular toxoplasmosis (OT). Methodology: Eight patients with OT underwent standardized ophthalmologic examination and fundus imaging. Macula and the lesions that could be visualized were evaluated by spectral domain optical coherence tomography (SOCT) at presentation. The scan acquisition protocols for SOCT included a radial line scan through the retinochoroiditis lesion, radial line macular scan, and horizontal volume scans at the macula. Results: The mean age of the five (62.5%) women and three (37.5%) men was 25.7±7.6 years. The mean logMAR ETDRS best-corrected visual acuity was 0.45 (Snellen equivalent, 20/50). SOCT findings of macula were normal in seven patients, and one patient had decreased retinal thickness from a healed chorioretinitis at the fovea. Of eight patients, two had 3+ vitreous haze, four had 2+ vitreous haze, and two had 1+ vitreous haze at presentation. OCT scans revealed vitreous hyperreflective dots in all patients with different densities in different radial scans. Hyperreflective dots were denser in macular scans of eyes in which the active lesion was closer to the fovea. Conclusions: In this study, visual impairment in majority of the patients was found to be related to vitreous cells and flare. Dense vitritis on macula scans and visual impairment were seen in the patients who had an active lesion closer to the fovea. SOCT may provide objective data of the cellular load of the eyes with posterior segment inflammation.

“…Imaging of congenital toxoplasmosis scars with OCT reveals retinal thinning, RPE hyper-reflectivity, excavation, intraretinal cysts, and fibrosis (5) . Toxoplasmic retinochoroidal scars can be classified in four different patterns: atrophic retinochoroidal scar, elevated scar, combined scar, and deep scars (6) . Similarly to toxoplasmosis, our patient's OCT disclosed retinal thinning and RPE hyper-reflectivity with marked atrophy of the outer retinal layer; however, minimal distortion of the inner layers was observed.…”
