Abstract Details

Purpose:

The aim of the study is to evaluate the efficacy and safety of the Nd YAG laser as a clinical procedure to eliminate/decrease the the visual disability created by the Weiss ring as a floater in patients suffering from posterior vitreous detachment and to study for any short/long term complications of the procedure

Setting:

Ophthalmology department of Saudi German Hospital, Riyadh -Saudi Arabia

Methods:

A total of 32 eyes of 32 patients were included in this study which is hospital clinic based observational and interventional study. All patients were subjected to complete ophthalmic evaluation including VA,IOP and a detailed Vitreoretinal examination. Weiss ring of varying shapes,density and locations were treated with Nd YAG Laser with varying laser power and other relevant parameters. Goldman contact lens was used with a clear viscous gel as a coupling agent The patients were followed up for 6-12 months. In 29 patients a single procedure was enough to treat the vitreous opacity,however 3 patients needed the procedure to repeated to make the outcome satisfactory

Results:

Out of 32 patients 29 patients were completely satisfied with the outcome of the procedure. One patient complained with break up of the main opacity into multiple small opacities instead of one large one in the visual axis. The other patient had a favorable shift in the position of the opacity away from the visual axis and a decrease in the size of the opacity and significantly decreasing the annoying feeling and disability created by the floater. None of the patients had any postoperative or intra operative complications. The patients were followed up for 6-12 months.

Conclusions:

YAG laser vitreolysis is a very effective and a safe technique of treating disabling vitreous opacity due to Weiss ring which can present as a ring like floater in a very high percentage of patients , for visually high demanding patients in our clinic practice without the risk of any serious intra or post op complications.
