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.

Amaç: Fakoemülsifikasyon cerrahisi sonrası kistoid maküla ödemi (KMÖ) sıklığı, risk faktörleri ve maküla kalınlık değişimlerinin Optik Koherens Tomografi (OKT) ile incelenmesi. Ge reç ve Yön tem: Okmeydanı Eğitim ve Araştırma Hastanesi Göz Hastalıkları Kliniğinde fakoemülsifikasyon tekniği ile katarakt cerrahisi geçirmiş 65 hastanın 99 gözü çalışmamıza dahil edildi. Tüm hastaların ameliyat öncesi ve ameliyat sonrası birinci gün, birinci hafta, birinci ay ve üçüncü ay fovea kalınlıkları, maküla hacmi ve ortalama maküla kalınlıkları OKT ile ölçüldü. Bulgular: Bu çalışmada KMÖ insidansı %3 olarak bulundu. Hastaların OKT ile yapılan ölçümlerinde ortalama fovea kalınlıkları ameliyat öncesi 250,4 (±18,5) μm, ameliyat sonrası birinci gün 252,08 (±23,2) μm, birinci hafta 261,4 (±27,8) μm, birinci ay 270,6 (±44,4) μm, üçüncü ay 265,4 (±41,6) μm olarak belirlendi. Ameliyat öncesi sonuçlar ile birinci hafta, birinci ay, üçüncü ay sonuçları arasında,birinci hafta ile birinci ay, üçüncü ay değerleri arasında istatistiksel olarak anlamlı fark bulunmuştur (p<0,01). Olguların 44'ünde (%44,4) kalınlık artışı tespit edilmiştir. Maküladaki kalınlık artışı en çok parafoveal bölgede meydana gelmiştir. Ameliyat esnasında görülen iris travması, arka kapsül açılması gibi zorlukların KMÖ gelişme riskini arttırdığı bulunmuştur (p=0,001). Sonuçlar: Katarakt cerrahisi sonrası subklinik maküla kalınlık artışı birinci haftada başlayıp, birinci ayda maksimum değerlere ulaşmaktadır. Özellikle komplike olan katarakt ameliyatlarında sonra KMÖ görülme sıklığı arttığından dolayı bu hastalar OKT ile yakın takip edilmelidir.

Ma te ri als and Met hods: This study included 99 eyes of 65 patients who underwent phacoemulsification surgery in OkmeydanıTraining and Research Hospital, Department of Ophthalmology. Foveal thickness, macular volume, and mean macular thickness were measured by OCT preoperatively and at 1 st day, 1 st week, 1 st , and 3 rd months postoperatively. Re sults: In this study, the incidence of postoperative CME was 3%. The mean central foveal thickness was preoperatively 250.4 (±18.5) μm, and postoperatively was 252.08 (±23.2) μm at 1st day, 261.4 (±27.8) μm at 1st week, 270.6 (±44.4) μm at 1st month, and 265.4 (±41.6) μm at 3 rd month. The statistically significant increase in foveal thickness was defined between preoperative and 1st week, 1st month, 3 rd month as well as between 1st week, 1st month, and 3rd month (p<0.01). Increase in macular thickness was demonstrated in 44 eyes (44.4%) which was most frequently located in the parafoveal region. Intraoperative complications like iris trauma, posterior capsule tear, and vitreous loss were increased risk of CME (p=0.001). Conclusion: Subclinical macular thickness increment begins at 1st wee...

is the only modifiable risk factor to slow down disease progression (1,2). Glaucoma is a challenging disease of the eye necessitating lifelong follow-up and the leading cause of irreversible vision loss worldwide (3). Objectives:The objectives of the study were to analyze the long-term results of trabectome surgery in Turkish patients with primary open angle glaucoma (POAG) and pseudoexfoliative glaucoma (PEXG) and to characterize the risk factors for failure. Methods: This single-center retrospective non-comparative study included 60 eyes of 51 patients diagnosed with POAG and PEXG, who underwent trabectome alone or phacotrabeculectomy (TP) surgery between 2012 and 2016. Surgical success was defined as a 20% decrease in intraocular pressure (IOP) or IOP≤21 mmHg and no further glaucoma surgery. Risk factors for further surgery were analyzed with the Cox proportional hazard ratio (HR) models. The cumulative success analysis was undertaken with the Kaplan-Meier method based on the time to further glaucoma surgery. Results:The mean follow-up period was 59.4±14.3 months. During the follow-up period, 12 eyes required additional glaucoma surgery. The mean pre-operative IOP was 26.9±6.8 mmHg. The mean IOP at the last visit was 18.8±4.7 mmHg (p<0.01). IOP decreased 30.1% from the baseline to the last visit. The average number of antiglaucomatous drug molecules used was 3.4±0.7 (range 1-4) preoperatively and 2.5±1.3 (range 0-4) at the last visit (p<0.01). The risk factors for further surgery requirement were determined as a higher baseline IOP value (HR: 1.11, p=0.03] and the use of a higher number of preoperative antiglaucomatous drug molecules (HR: 2.54, p=0.09). The cumulative probability of success was calculated as 94.6%, 90.1%, 85.7%, 82.1%, and 78.6% at three, 12, 24, 36, and 60 months, respectively. Conclusion:The success rate of trabectome was 67.3% at 59 months. A higher baseline IOP value and the use of a higher number of antiglaucomatous drug molecules were associated with an increased risk of further glaucoma surgery requirement.
