Title: [abstract] LENS MORPHOLOGY EVALUATION IN PATIENTS WITH HYPERBARIC OXGYEN THERAPY - INDUCED MYOPIA
Author: Khan, B; Evans, AW; Easterbrook, M
Abstract: Introduction / Background: Myopic refractive changes in patients undergoing scheduled hyperbaric oxygen therapy have been well documented. We have previously demonstrated that over half of patients develop a significant myopic shift. Previous studies have determined that both axial length of the eye and corneal curvature remain constant during therapy, thus implicating the lens as the site of refractive change. The aim of this study was to directly investigate the morphology of the lens to ascertain its behaviour during scheduled therapy. Materials / Methods: Our previous study demonstrated that women below 60 years of age maybe more likely to exhibit refractive changes. Patients were recruited based on, but not excluded by, these criteria. Patients were assessed at pre, intra, and post-therapy visits. Each assessment included best corrected visual acuity, cycloplegic refraction and slit lamp examination. Ultrasound biomicroscopy was then utilized to measure lens anterior-posterior thickness under cycloplegia. Results: Results will be presented at the time of presentation. Summary / Conclusion: This study will help to elucidate the behaviour of the lens during hyperbaric oxygen therapy. An increase in lens thickness would suggest a swelling of lens while a constant lens thickness would suggest sclerosis and a biochemical change in the lens proteins.
