Title:  Myopic Shifts in Hyperbaric Oxygen Therapy: Clinical Patterns, Mechanisms, and Management

Learning Objectives:

1. Describe the pathophysiological mechanisms underlying HBOT-induced myopia, including lenticular oxygen toxicity, refractive index changes, and oxidative stress effects on the crystalline lens.

2. Identify clinical patterns and risk factors associated with hyperbaric-induced myopic shifts, including treatment dose (ATA, duration, number of dives), patient age, and comorbidities.

3. Differentiate transient HBOT-induced myopia from other ocular complications, including nuclear cataract formation, retinal pathology, and barotrauma-related visual symptoms.

4. Counsel patients effectively regarding expected visual changes, timelines for onset and resolution, and implications for daily functioning (e.g., driving, reading).

5. Implement practical management strategies to mitigate visual side effects, including treatment modifications, monitoring approaches, and indications for ophthalmology referral.
