A primary intraocular hydatid cyst
Acta Ophthalmologica
|December 1, 1991
Abstract:
Ultrasonography and computerized tomography (CT) of the painful and blind right eye of a 13-year-old girl showed a cystic mass almost filling the vitreous cavity and narrowing the anterior chamber. The histopathologic diagnosis of the enucleated eye was an echinococcus cyst. Abdominal ultrasonography, brain CT and chest X-rays gave no abnormal findings when first examined, nor during the follow-up 18 months after surgery. Indirect hemagglutination test was negative at the last control. The case was accepted as a primary hydatid cyst (echinococcosis) of the eyeball.

Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
