Abstract
Purpose

To report the epidemiological, clinical and prognostic features of ocular toxoplasmosis in an immigrant population in the Barcelona area.

Methods

A retrospective non-comparative observational study was conducted on a case series of 22 immigrant patients diagnosed with ocular toxoplasmosis by ophthalmoscopic and serological findings. Demographic, clinical and laboratory data were analysed under baseline conditions. The minimum follow-up was 6 months.

Results

Bilateral involvement was observed in five of the 22 patients (22.7%), a total of 27 eyes being affected by active lesions and old scars. Atypical presentations, including multiple or large necrotizing lesions, were observed in 5 eyes (25%). In 15 eyes (75%) the retinal lesions were associated with intraocular inflammation. Vitreoretinal complications were observed in eight eyes (29.6%), with 22.7% of them requiring vitreous surgery.

Conclusions

In immigrant patients from our area in Barcelona, ocular toxoplasmosis has specific clinical and prognostic features, including high rates of atypical presentations, frequent intraocular inflammation, and vitreoretinal complications, requiring surgery in most of the cases.

Resumen
Propósito

Describir las características epidemiológicas, clínicas y pronósticas de la toxoplasmosis ocular en un grupo de población inmigrante de nuestra área.

Método

Para ello se realizó un estudio descriptivo retrospectivo no-comparativo de 22 pacientes inmigrantes diagnosticados de toxoplasmosis ocular mediante oftalmoscopía y serología. Se evaluaron datos demográficos, clínicos y de laboratorio basalmente. Los pacientes fueron seguidos por un período mínimo de 6 meses.

Resultados

Cinco de los 22 pacientes (22,7%) tenían afectación bilateral, presentando lesiones activas y/o cicatriciales un total de 27 ojos. En cinco ojos (25%) se evidenciaron lesiones atípicas retinianas en forma de múltiples focos de retinitis o áreas extensas de necrosis. En quince ojos (75%) las lesiones retinianas se acompañaron de signos inflamatorios intraoculares. En ocho ojos (29,6%) aparecieron complicaciones vítreoretinianas precisando de cirugía de vitrectomía cinco de ellos (22,7%).

Conclusiones

La toxoplasmosis ocular en pacientes inmigrantes de nuestra área tiene unas características clínicas y pronósticas específicas que incluyen el presentar unas tasas elevadas de formas atípicas, acompañarse frecuentemente de inflamación intraocular y tener asociadas complicaciones vítreo-retinianas que requieren en la mayoría de los casos cirugía de vitrectomía.
