Surgical treatment of secondary refractory glaucoma in chronic uveitis with corneal dystrophy (clinical case)

BACKGROUND: Uveitis is the inflammation of the iris, ciliary body, vitreous, retina, or vascular membrane, in which the most common complication is a secondary increase in intraocular pressure that is difficult to compensate with antihypertensive drugs. Ahmed valve implantation in uveal glaucoma is an effective surgical method to reduce intraocular pressure. CLINICAL CASE DESCRIPTION: In the Department of Surgical Treatment of Glaucoma of the S. Fyodorov Eye Microsurgery Federal State Institution, Ahmed valve implantation was performed in two patients with refractory, repeatedly operated uveal glaucoma. As a result of valve implantation, in both cases, compensation of intraocular pressure within up to 15 months after surgery was possible.
