Free-Floating Pigmented Vitreous Cyst.

Here we report a case of a congenital, free-floating pigmented vitreous cyst in a child. A 12-year-old male was referred to the Ophthalmology Clinic for amblyopia on his left eye. Ophthalmologic examination revealed that the visual acuity was 20/20 in the right eye and 20/35 in the left eye. Findings of the anterior segment examination were normal. On dilated fundus examination, a free-floating pigmented vitreous cyst was detected in the left eye. (Figure 1). Real-time ultrasonography also confirmed the hyperechogenic spherical body floating in the middle of the vitreous.
