“…The mean percentage of hexagonal cells in PXG eyes in our study was 50.9 ± 2.47 which was in accordance to previous studies as 54.9 ± 10.9 [35], 56.4 ± 7.5 [35], 57.1 ± 7.1 [36]. The mean central corneal thickness in PXG patients has been reported as 493 ± 33 [37], 507 ± 25 [38], 528 ± 30 [39] which was comparable to our study group 556.4 ± 28.95. In our study there was a significant difference in the CCT in PXG patients compared to the normal group 572.5 ± 19.91.…”

“…However, Gorezis et al (14) found that the CCT was significantly thinner in patients with pseudoexfoliative glaucoma. Similarly, Aghaian et al (25) and Bechmann et al (26) reported that the CCT was significantly lower in patients with pseudoexfoliative glaucoma, low-tension glaucoma, and primary open-angle glaucoma than in healthy individuals. Inoue et al (15) examined the CCT and the endothelial morphology of the cornea in 26 eyes of 21 PXS patients (seven eyes with glaucoma and 19 eyes without glaucoma).…”

Approved by the following research ethics committee: Süleyman Demirel University (# 72867572-050). ABSTRACT Purpose:To evaluate anterior segment parameters in patients with pseudoexfoliation syndrome (PXS) using Scheimpflug imaging. Methods: Forty-three PXS patients and 43 healthy control subjects were included in this cross-sectional study. All participants underwent a detailed ophthalmologic examination. Anterior segment parameters were measured using a Scheimpflug system. Results: Considering the PXS and control groups, the mean corneal thicknesses at the apex point (536 ± 31 and 560 ± 31 µm, respectively, p=0.001), at the center of the pupil (534 ± 31 and 558 ± 33 µm, respectively, p=0.001), and at the thinnest point (528 ± 30 and 546 ± 27 µm, respectively, p=0.005) were significantly thinner in PXS patients. Visual acuity was significantly lower (0.52 ± 0.37 versus 0.88 ± 0.23, p<0.001) and axial length was significantly longer (23.9 ± 0.70 mm versus 23.2 ± 0.90 mm, p=0.001) in the PXS eyes than in the control eyes. There were no statistically significant differences in the mean values of keratometry, anterior chamber angle, anterior chamber depth, corneal volume, and anterior chamber volume between the PXS and control eyes. Conclusions: The patients with PXS had thinner corneas, worse visual acuity, and longer axial length compared with those in the healthy controls.

ÖzetAmaç: Katarakt cerrahisi öncesi farklı kornea kalınlığı olan hastalarda ameliyat sonrası değişimleri tespit etmek. Ge reç ve Yön tem: Senil katarakt tanısıyla komplikasyonsuz katarakt cerrahisi geçiren 70 hastanın 90 gözü prospektif olarak çalışma kapsamına alındı. Santral kornea kalınlığı (SKK) ultrasonik pakimetri ölçüldü. Hastalar ameliyat öncesi SKK'ya göre 4 grupta değerlendirildi (450-500 μm, grup-1; 501-550μm, grup-2; 551-600 μm, grup-3; 601-650 μm, grup-4). SKK ameliyat öncesi ve sonrası 1., 2., 4. ve 8. haftalarda ölçüldü. İstatiksel analiz için 'ki-kare testi' ve 'tek yönlü varyans analizi' kullanıldı. So nuç lar: Birinci haftada santral kornea kalınlığındaki artış grup 1'de en yüksek olup 71,3 μm olarak tespit edildi. Grup 2'deki artış 43,4, grup 3'de 35,1, grup 4'de 16,6 μm idi. Tüm gruplarda 1. haftada SKK'da artış anlamlı idi (p<0,05). Grup-1'deki artış grup-3 ve grup-4'teki artıştan anlamlı olarak daha yüksekti (grup-1 ve grup-3; p=0,025, grup-1 ve grup-4; p<0,01). Grup-2'deki artış ise grup-4'teki artıştan anlamlı olarak yüksek bulundu (p=0,032). İkinci haftadan itibaren SKK'da düşüş görüldü. SKK'da ameliyat öncesi değerlere dönüş grup-1'de 8. haftada grup-2 ve grup-3'de 4. haftada, grup-4'te ise 2. haftada tespit edildi. Tar t›fl ma: İnce kornealarda katarakt ameliyat sonrası santral kornea kalınlığındaki artış daha belirgin olup stabilizasyon daha geç gerçekleşmektedir. ( Sum maryPur po se: To evaluate the changes in central corneal thickness (CCT) in patients with different values before cataract surgery. Ma te ri al and Met hod: 90 eyes of 70 patients who had undergone uneventful cataract surgery because of senile cataract were included in this prospective study. The CCT was measured by ultrasound pachymetry. The patients were evaluated in 4 groups according to preoperative CCT values (group 1: 450-500 μm, group 2: 501-550μm, group 3: 551-600μm, and group 4: 601-650μm). The CCT was measured preoperatively and at 1st, 2 nd , 4 th , and 8 th weeks postoperatively. The chi-square test and one-way analysis of variance test were used for statistical analysis. Re sults: The increase in CCT was highest in group 1 determined as 71.3 μm. The increase in group 2 was 43.4, 35.1 in group 3, and 16.6 μm in group 4. The increase in CCT was significant in all groups at week 1 ( p<0.05). The increase in group 1 was statistically significant than in groups 3 and 4 (group 1 and group 3, p=0.025; group 1 and group 4, p<0.01). The increase in group 2 was also statistically significant than in group 4 (p=0.032). The CCT was decreased after the 2 nd week. The recovery of CCT to preoperative values was determined at 8 th week in group 1, 4 th week in groups 2 and 3, and 2 nd week in group 4. Dis cus si on: In thin corneas, the increase in central corneal thickness is more prominent and stabilization occurs in a longer time after cataract surgery. (Turk J Ophthalmol 2013; 43: 145-8)
