근시안에서 각막 중심부와 주변부의 두께를 측정하여 굴절이상 도에 따른 중심부와 주변부 두께의 상관관계와 각막두께의 변화상에 대하여 알아보고자 하였다. 20세에서 49세까지의 99명 198안을 대상으로 Orbscan Topography System(Orbtex, Inc, USA)을 사용하여 중심부 두께와 좌 우안 중심부를 기준으로 상 하, 이 비측 각 2mm 지점에서 주변부 두께를 측정하여 성별, 연령별, 좌 우안별 그리고 굴절이상도에 따라 분석하였다. 전체 대상자의 각막 중심부 두께는 $530.12{\pm}43.41{\mu}m$때, 주변부 두께는 상측 $591.91{\pm}36.88{\mu}m$, 하측 $561.04{\pm}41.82{\mu}m$, 비측 $584.23{\pm}41.97{\mu}m$, 이측 $567.35{\pm}43.25{\mu}m$로 측정되어 중심부와 주변부 각막두께의 차이는 유의한 차이를 보였다. 그러나 굴절이상도, 연령, 성별 그리고 좌 우안에 따른 각막두께는 통계적으로 유의한 차이는 없었다.

Purpose: Changes in corneal thickness after wearing hydrogel lens and silicone-hydrogel lens with different oxygen transmission rates wew syudied. Methods: Experiments were performed on 11 subjects(22 eyes). corneal thickness was measured after wearing contact lenses for 8 hours. Corneal thickness was measured using ORB Scan II(ver. 3.14) Results: In the results of the corneal thickness measurement by direction, in the case of the hydrogel-tor lens, the center thickness was $33.63{\mu}m$, the nasal was $34.29{\mu}m$, the temporal was $27.17{\mu}m$, the inferior was $27.17{\mu}m$, the superior was $18.90{\mu}m$, and change rates were 6.28%, 5.71%, 5.40%, 4.75% and 3.09%, respectively. In the results of the corneal thickness measurement by diameter, in the case of the hydrogel-tor lens, the center was $33.63{\mu}m$, the mid-peripheral was $28.19{\mu}m$, the peripheral was $24.18{\mu}m$, and change rates were 6.28%, 4.76%, and 3.79%, respectively. Conclusions: The hydrogel lenses with relatively low oxygen transmission rates resulted in a significant increase in thickness over the entire cornea compared to silicon-hydrogel lenses with high oxygen transmission rates.

Purpose: The aim of this study was to determine the distribution of the cornea thickness and intra ocular pressure Korean adult of 20 to 24 year old using the Pentacam and tonometer. Methods: The subjects of this study were 43 Korean adults with healthy eyes. Corneal thickness was measured with Pentacam device. The intra ocular pressure was measured with tonometer. Data was analyzed by means of the Pearson's correlation cofficient. P-values<0.001 were considered statistically significant. Results: Mean age of subjects was 20.41±0.86 years. The mean +/- intra ocular pressure of the right eye and left eye were 16.236±2.523mmHg and 16.971±1.992mmHg, respectively. The mean central corneal thickness of the right eye and left eye was 545.324±38.682㎛ and 547.442±33.778㎛, respectively. No significant difference in central corneal thickness was found between the right and left eyes. But, there was a statistically significant difference between central cornea thickness and peripheral cornea thickness around 4 mm of central cornea(p<0.001, Pearson's correlation). However there was no statistically significant difference between central cornea thickness and intra ocular pressure. Conclusion: The results of this study could be used as a clinical reference data for diagnosis and treatment of cornea in Korean adult.
