Abstract Details

Purpose:

This study aimed to investigate the effect of Hyperbaric Oxygen Therapy (HBO) treatment on central corneal thickness using anterior segment optical coherence tomography (AS-OCT).

Setting:

Ophthalmology Department, Military Hospital of Tunis, Tunisia.

Methods:

Forty healthy subjects (20 males and 20 females) undergoing HBO treatment were enrolled. Best-corrected visual acuity was recorded before HBO treatment, and anterior and posterior segment examinations were performed. Central corneal thickness was measured with anterior segment optical coherence tomography (AS-OCT) before and immediately after HBO treatment, which lasted 120 min at 2.5 atmospheres absolute with three 30-min oxygen and two 5-min air-breathing periods.

Results:

Forty healthy nondiabetic subjects (20 males and 20 females, mean age 58.5 ﾱ 8,5 years) were enrolled. The subjects were prescribed HBO treatment for problem wounds (n = 25), radionecrosis (n = 5), sudden hearing loss (n = 8), chronic osteomyelitis (n = 2). The central corneal thickness was significantly reduced after HBO treatment (575.5 ﾱ34.8 vs. 568.0 ﾱ 34.8 p<0,05).

Conclusions:

A single exposure to HBO treatment reduced the central corneal thickness in healthy subjects. However, the change in central corneal thickness was minor.
