Alemtuzumab (Campath-1H) is a humanized anti-CD52 monoclonal antibody used in the treatment of multiple sclerosis (MS). Studies demonstrate significant reduction in relapse risk and the risk of accumulating sustained disability. Adverse events include infusion-associated reactions, infections, and secondary autoimmunity. Systemic thyroid disease is the most common secondary autoimmune event and affects up to approximately 30% of treated patients. This is the first description of the ocular findings and management in a case of thyroid eye disease (Graves' Ophthalmopathy [GO]) following alemtuzumab therapy. The ocular disease was managed conservatively while the systemic Graves' was managed with thyroidectomy.

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...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Glaucoma: Overview01:25

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...
