Pigmented congenital vitreous cyst.

PURPOSE

To describe the clinical findings in a case with a typical pigmented congenital vitreous cyst and to discuss its differential diagnosis. METHODS/CASE REPORT: A 24-year-old woman complaining of floaters and blurring of vision during eye movements in the right eye was examined.

RESULTS

A diagnosis of congenital vitreous cyst was made after detailed vitreoretinal examination, B-scan ultrasonography (eye and abdomen), computerized tomography of brain, chest radiogram, serologic tests for Echinococcosis and Cysticercosis in the serum, and complete blood count for eosinophilia. Clinical presentation and the patient's complaints remained unchanged during 3 years of follow-up.

CONCLUSIONS

Congenital vitreous cysts are benign lesions. Differential diagnosis from acquired cysts requires careful clinical examination and appropriate laboratory tests.
