Evaluation of barriers between anterior and posterior compartments during Nd:YAG capsulotomy in diabetic patients

Abstract

Pelin Özyol, Erhan Özyol Department of Ophthalmology, Ünye State Hospital, Ordu, TurkeyWe have read the article by Awan et al1 with great interest. We want to add a few comments on the paper.Neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser is needed to revert the deficiency of visual acuity caused by posterior capsule opacification. However, this procedure involves an alteration of ocular compartments that increases the risk of the patient suffering severe posterior segment pathologies. The space between the posterior capsule of the lens and the anterior hyaloid membrane is defined as Berger space. It is thought to act as a mechanical barrier separating the physiological and functional anterior portion of the eye from the posterior portion of the eye.2 Any factor affecting the posterior capsule may have a potential effect on the anterior hyaloid membrane, due to the close anatomical relationship during Nd:YAG laser capsulotomy or phacoemulsification.View original paper by Awan and colleagues.
