Introduction: toxoplasmosis is a frequent zoonosis caused by an obligate intracellular parasite:  toxoplasma gondii. The most frequent cause is posterior uveitis and can provoke severe ophthalmic sequels. Objective: to characterize clinical and epidemiological behavior, natural history and main complications of patients suffering from active-ocular toxoplasmosis at the Ophthalmologic Center in Pinar del Rio province.  Material and method: an observational, descriptive and cross sectional study was conducted in patients having the diagnosis of active-ocular toxoplasmosis, during January 2011 and October 2012. The target group was comprised of the totality of patients attending to the center with the diagnosis of ocular toxoplasmosis (34), and the sample included those presenting the active form of infection (14). Results: patients between 30 and 39 years old prevailed, with a slight prevalence of female sex. Blurred vision was the most frequent symptom, mostly the lesion appeared in zone I of the retina. Necrotizing lesions of toxoplasmic retinochoroiditis accompanied by vitritis of variable intensity was the most frequent ophthalmic finding, prevailing patients with a better visual acuity below 0,3 after the treatment. Macular edema and ocular hypertension resulted in the most repeated complications. Conclusions: clinical characteristics of patients coincided with those described in medical literature. The degree of visual affection was related to the site of lesions and complications.
