Pigmented Free-floating Vitreous Cyst

Abstract

A 45-year-old man presented with a mobile shadow in the central visual field of his left eye for the preceding 4 months. His visual acuity was not affected. Funduscopy showed a brownish, oval-shaped structure floating in the vitreous cavity of the left eye. B-scan ultrasound demonstrated an oval-spherical hypoechogenic structure floating at the posterior pole. The absence of pertinent medical history and normal results from systemic exploration suggested a congenital etiology. The condition was observed regularly without any evidence of change. Differential diagnosis of vitreous cysts is important in order to establish an adequate therapeutic approach.

Idiopathic pigmented vitreous cyst

“…Observation is appropriate when a patient is asymptomatic or symptoms are mild (Caminal-Mitjana et al 2014). For severe symptoms, treatment options include Argon or Nd:YAG laser disruption of the cyst and pars plana vitrectomy with cyst excision (Nork & Millecchia 1998).…”
