Abstract Details

Purpose:

Nd:YAG laser iridotomy was proposed to reverse iris concavitiy thus reducing pigment granule release in pigment dispersion syndrome (PDS) or pigmentary glaucoma (PG). The purpose of the study was to evaluate the differences in the biometric parameters of iridocorneal angle and iris structure measured by anterior segment optical coherence tomography (AS-OCT) in PDS and PG before and after Nd:YAG laser iridotomy.

Setting:

Beyoglu Eye Training and Research Hospital

Methods:

All eyes were examined with AS-OCT (Visante®) before and after Nd:YAG laser iridotomy in standart room illumination. All parameters were compared statistically before and after Nd:YAG laser iridotomy.

Results:

The mean age of 18 eyes were 39.8±13.7. The mean visual acuity was 0.82 ±0.32. All iridocorneal angle parameters (angle- opening distance 500 and 750 (AOD) , scleral spur angle (SSA), trabecular–iris space (TISA) 500 and 750) were significantly less wide after laser iridotomy. Anterior chamber depth was significantly less deep after laser iridotomy. With regard to iris measurements, iris thickness in the middle of the iris and iris bowing were all statistically different before and after laser iridotomy. Also, there were significant difference in iris shape before and after laser iridotomy.

Conclusions:

Laser iridotomy can restore the iris shape thus changing the iris bowing and reducing the iridolenticular contact in eyes with PDS and PG. AS-OCT is helpful in understanding the changes in anterior segment biometric parameters of iridocorneal angle and iris structure before and after laser iridotomy.
