Abstract

Purpose: To investigate the factors associated with glaucoma in patients with pseudoexfoliation syndrome by comparing features of the anterior segments and ocular biometry according to the presence or absence of open-angle glaucoma in pseudoexfoliation syndrome. Methods: We analyzed 96 patients (115 eyes) diagnosed as having pseudoexfoliation syndrome in this study. The patients were divided into two groups of simple pseudoexfoliation syndrome (64 patients, 76 eyes) and pseudoexfoliation glaucoma (32 patients, 39 eyes). We compared the age, sex, underlying disease, location of pseudoexfoliative material, iris change, degree of nuclear cataract, pupil dilatation, corneal endothelial cell counts, central corneal thickness, anterior chamber depth, axial length, corneal curvature, and intraocular pressure (IOP). Results: There were no significant differences between the two groups in terms of age (p = 0.694), sex (p = 0.161), diabetes (p = 0.440), hypertension (p = 0.238), pseudoexfoliative material observed in anterior capsule (p = 0.700), pupillary margin (p = 0.210), iris depigmentation (p = 0.526), pupillary ruff loss (p = 0.708), degree of nuclear cataract (p = 0.617), pupil dilatation (p = 0.526), central corneal thickness (p = 0.097), anterior chamber depth (p = 0.283), axial length (p = 0.095), or horizontal and vertical corneal curvature (p = 0.066 and 0.306, respectively). In pseudoexfoliation glaucoma, significantly higher IOP (p = 0.026), a high frequency of membrane formation (p = 0.047), and decreased corneal endothelial cell counts (p = 0.048) were observed. Conclusions: Pseudoexfoliation syndrome with open-angle glaucoma was shown to be associated with high IOP, decreased corneal endothelial cell counts, and a high frequency of membrane formation. Therefore, when such changes are observed in pseudoexfoliation syndrome patients, a higher risk of open-angle glaucoma should be recognized, and careful attentionis required accordingly.

목적: 거짓비늘증후군에서 개방각녹내장 병합 유무에 따른 전안부 소견과 생체 계측치들을 비교 분석하여 거짓비늘증후군에서 녹내장 발생과 관련된 인자들을 알아보고자 하였다. 대상과 방법: 본원에서 거짓비늘증후군으로 진단된 96명(115안)을 대상으로 하였으며, 단순거짓비늘증후군 64명(76안)과 녹내장 병합 거짓비늘증후군 32명(39안)의 두 군으로 나누어 나이, 성별, 기저질환, 거짓비늘물질이 관찰된 부위 및 홍채의 변화, 핵백내장 정도, 산동 정도, 각막내피세포 수, 중심각막두께, 전방깊이, 안축장, 각막곡률, 안압을 비교하였다. 결과: 두 군 간 나이(p=0.694), 성별(p=0.161), 당뇨(p=0.440), 고혈압(p=0.238), 거짓비늘물질의 관찰 위치로 전낭, 동공연(p=0.700, 0.210), 홍채의 변화 양상으로 동공연 탈색소, 주름 소실(p=0.526, 0.708), 핵백내장 정도(p=0.617), 산동 정도(p=0.526), 중심각막두께(p=0.097), 전방깊이(p=0.283), 안축장(p=0.095), 수평, 수직 각막곡률(p=0.066, 0.306)에서 유의한 차이를 보이지 않았으며, 녹내장병합거짓비늘증후군에서 안압이 높고(p=0.026) 동공연의 막형성이 많으며(p=0.047), 각막내피세포 수의 감소(p=0.048)가 유의하게 관찰되었다. 결론: 거짓비늘증후군에서 개방각녹내장이 병합된 경우 높은 안압, 각막내피세포 수 감소, 동공연의 막형성 소견이 유의하게 비교 관찰되므로 이러한 변화 양상이 관찰될 때 녹내장 병합 가능성이 높음을 인지하여 경과관찰 시 세심한 주의가 필요할 것으로 사료된다.
