Purpose

To evaluate changes in anterior chamber parameters after hyperbaric oxygen therapy (HBOT) based on ultrasound biomicroscopy (UBM).

Setting

Ophthalmology Department, Military Hospital of Tunis, Tunisia.

Methods

The study was conducted in patients who received HBOT for conditions other than eye diseases. Patients underwent thorough eye exam including refraction, visual acuity, and dilated fundus examination. Anterior segment imaging was performed on each eye using UBM (Aviso Lin-50; Quantel Medical). The following biometric parameters of the anterior segment were measured: lens vault (LV), iris Thickness (IT), angle opening distance (AOD 500), angle recess area (ARA 750) and trabecular iris space area (TISA 750). All subjects were examined at baseline and every ten sessions until the end of HBOT treatment. A 12-week follow-up was also performed.

Results

In total, 74 patients (26 female) were included in the study. The mean age was 48,03±13,42 years. We analyzed the evolution of the biometric parameters of the anterior segment by stratifying to the side (right and left) and compared the data from the periodic examination to the baseline values. Regardless of the side studied, we did not notice any significant changes in the iridocorneal angle parameters (AOD 500, ARA 750, TISA750) before and during HBOT (P = NS).

Conclusion

Changes in biometric parameters of the anterior segment before and during HBO2 therapy were not statistically significant. However, further studies are warranted to confirm our results.
