Phacoemulsification Results of Eyes with Primary Angle Closure and Primary Angle Closure Glaucoma Using the Pentacam System
Keywords:Glaucoma, angle closure, phacoemulsification, intraocular pressure
Aim: To evaluate the phacoemulsification results of patients with primary angle closure (PAC) and primary angle closure glaucoma (PACG) using the Pentacam system.
Method: This retrospective cohort study included patients with PAC and PACG who underwent phacoemulsification and intraocular lens implantation between 2018 and 2021 in one tertiary center. Anterior chamber parameters measured using the Pentacam system and gonioscopic and intraocular pressure (IOP) changes were evaluated preoperatively and postoperatively.
Results: Nineteen eyes of 13 patients with PAC and PACG were included in the study. The mean age of the patients was 63.2 years, and 30.8% were male. The mean preoperative and postoperative third-month IOP was 21.0 ± 7.4 mmHg (11-40) and 13.7± 2.5 mmHg (9-18), respectively (p < 0.01). The mean preoperative anterior chamber angle (ACA) measured by the Pentacam system was 21.07 ± 4.16° (13-27). The mean preoperative anterior chamber depth (ACD) and the anterior chamber volume (ACV) measured by the Pentacam system were 1.79 ± 0.24 mm (1.39-2.22) and 72.55 ± 20.64 mm3 (45-109), respectively. The postoperative third-month topographic measurements were as follows: mean angle, 35.76 ± 7.32° (20.1-46.9); mean ACD, 3.52 ± 0.95 mm (1.15-4.46); and mean ACV, 133.21 ± 25.21 mm3 (81-173) (p < 0.01).
Conclusion: Pentacam is a useful system to evaluate anterior segment changes after phacoemulsification in patients with PAC and PACG. Phacoemulsification was found to result in significant IOP reduction in these patients.
