Abstract
AbstractPurpose To evaluate the anterior chamber variations after‐iridotomy with Nd: Yag laser in eyes with narrow angle.Methods Twenty one patients with shalow anterior chamber were studied. Spectral domain OCT (Heidelberg, Germany) was performed before and seven days after laser peripheral iridotomy treatment in all cases. Spetial attention was taken to evaluate angle changes. Main measures were: anterior chamber volumen, central anterior chamber depth and temporal angle wide.Results Thirty two eyes of twenty one patients , 15 females and 6 males, age average 66.28 years old were measured. The preoperative angle wide at the temporal angle was 25.9 ± 4,8 degrees and postoperative was 27.1 ± 10 degrees. Morphological changes were evident with a deeper chamber and disruption in iris parenchyma.Conclusion Spectral domain OCT is a potential tool to evaluate changes in anterior chamber in narrow angle someted to iridotomy with Nd: Yag laser. The procedure is effective to increase anterior chamber volumen, central anterior chamber depth and angle wide in all cases.
