Summary
Hyperbaric oxygen therapy (HBOT) shows promise for treating branch retinal artery occlusion (BRAO). This treatment can improve visual acuity in patients experiencing this ophthalmic emergency.
Area of Science:
- Ophthalmology
- Vascular Medicine
- Emergency Medicine
Background:
- Retinal artery occlusion (RAO) is an ophthalmic emergency often linked to cardiovascular disease.
- Central RAO (CRAO) can cause severe vision loss, while branch RAO (BRAO) typically presents with milder symptoms.
- The underlying pathology of RAO mirrors that of ischemic stroke, involving retinal artery blockage and subsequent infarction.

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
554
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

Open Angle Glaucoma: Treatment
928
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.

Angle Closure Glaucoma: Treatment
1.1K
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...
