Glaucoma: Overview

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: 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: Treatment

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Summary

Head and neck surgery can cause severe vision loss due to artery embolisation. Intra-operative injections may lead to unexpected, devastating ocular complications affecting the ophthalmic artery.

Area of Science:

Ophthalmology
Vascular Surgery
Head and Neck Surgery

Background:

Ocular complications following head and neck surgery are rare but can be severe.
Understanding the potential risks associated with intra-operative substances is crucial.

Observation:

Two patients experienced sudden, severe visual acuity loss post head and neck surgery.
Ophthalmic examination revealed occlusion of the ophthalmic and central retinal arteries in both cases.

Findings:

The physiopathology identified was embolisation of intra-operatively injected substances.
Embolisation likely occurred through anastomosing branches connecting the external and internal carotid arteries.

Implications:

This highlights a critical risk of head and neck procedures involving injections.
Awareness and preventative strategies are needed to mitigate these devastating ocular complications.
