Summary
Hyperbaric oxygen therapy (HBOT) shows promise for restoring vision in patients with central retinal artery or vein occlusion. Prompt treatment with HBOT may lead to significant visual recovery in these emergent cases.
Area of Science:
- Ophthalmology
- Vascular Medicine
- Hyperbaric Medicine
Background:
- Central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) are critical conditions leading to vision loss.
- Prompt intervention is crucial for potentially salvaging vision in these ophthalmic emergencies.
Observation:
- Six patients with CRAO and CRVO were treated with hyperbaric oxygen (HBOT).
- Three patients achieved near-complete vision restoration, and one experienced marked improvement.
Findings:
- The study observed significant visual recovery in a majority of patients treated with HBOT.
- These results align with existing literature indicating a 65-70% improvement rate for CRAO patients undergoing HBOT.
Implications:
- Rapid referral and initiation of HBOT are recommended for suspected CRAO and CRVO cases.
- Administering 100% oxygen via non-rebreather mask should commence immediately upon diagnosis, pending HBOT.
- Physicians should consider HBOT as an effective treatment modality for these occlusive retinal events.

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,...

01:27Open Angle Glaucoma: Treatment
909
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.
