ABSTRACT

Purpose: To measure the anterior chamber changes in eyes with shallow anterior chamber and narrow angle after iridotomy with Nd:Yag laser with Pentacam. Design: Prospective, longitudinal and descriptive.
Patients: We included 13 patients (26 eyes) detected with narrow angle that required iridotomy with Nd:Yag laser.
Methods: Pentacam study was performed to the patients before the iridotomy with Nd:Yag laser and the study was repeated one month after the procedure. Main measures: Central and medial periphery anterior chamber, anterior chamber volume and angle wide.
Results: 26 eyes of 13 patients were studied, all of them were females, age average 65.08 years old. The preoperatory anterior chamber depth was 2.28 ± 0.33 mm and postoperatory was 2.31 ± 0.35 mm (p = 0.008). The anterior chamber depth preoperatory at the superior medial periphery was 1.31 ± 0.27 mm and postoperative was 1.45 ± 0.21 mm (p = 0.000). The anterior chamber depth preoperatory at the inferior medial periphery was 1.55 ± 0.26 mm and postoperative was 1.70 ± 0.23 mm (p = 0.000). The anterior chamber depth preoperatory at the nasal medial periphery was 1.38 ± 0.29 mm and postorirative was 1.46 ± 0.21 mm (p = 0.003). The anterior chamber depth preoperatory at the temporal medial periphery was 1.53 ± 0.24 mm and postoperative was 1.73 ± 0.26 mm (p = 0.000). The preoperative anterior chamber volume 100.81 ± 16.93 mm³ and postoperative was 122.42 ± 18.89 mm³ (p = 0.000). The preoperative angle average was 26.63± 5.97R and postoperative was 27.40 ± 5.12R (p = 0.044). There were no pre and postoperative statistical significant change in the pupilar diameter. The corneal paquimetry and the corneal queratometries did not change.
Conclusions: This study shows quantitatively, that changes in the volume and in the depth of the anterior chamber, as well as the angle wide, are statistical significant after iridotomy with Nd:Yag laser in patients with narrow angle.
