Congenital Vitreous cyst, A Rare Diagnosis to be Aware of : A Case Report

Vitreous cysts in children are rare. We report the case of a 5-year-old child who presented to the consultation department with the sensation of a floating body in the left eye, the position of which changed with eye movements, without any drop in visual acuity or notion of associated ocular trauma. On slit-lamp examination, the left eye showed a solitary pigmented cyst floating in the vitreous. After ruling out other possible etiologies, the diagnosis of congenital vitreous cyst was made. Treatment abstention was indicated for our patient.
