Histologic and immunohistochemical features of a vitreous cyst.
OBJECTIVE
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.
