Histologic and Immunohistochemical Features of a Vitreous Cyst

Purpose: To report the histologic and immunohistochemical features of a congenital vitreous cyst.

Methods: Interventional case report with immunohistochemical correlation. A 58-year-old woman with known vitreous cyst since childhood had an enlarging visual floater. The vitreous cyst was removed by pars plana vitrectomy and central vision was restored.

Results: Pathology confirmed a vitreous cyst derived from neural and glial tissue and consistent with retinal origin.

Conclusions: Congenital vitreous cysts, derived from neural and glial tissue, can be safely removed using pars plana vitrectomy.
