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.

Purpose. This study was to investigate the relationship between the palpebral fissure size and the exophthalmos in a population of Korean adult women subjects with normal eye status. Methods. From November 2012 to September 2013, The authors analyzed the morphological values in 73 Korean adults population. The test was performed using the Hertel exophthalmometer and verner califer. Analysis of subjects data were recorded using the spss version 20.0 a statistical program (IBM Co, Armonk, NY USA). Results. The average age of the 73 subjects (146 eyes) was (21.219+/-0.261)mm. the average value of palpebral fissure was (25.110+/-1.646)mm in width and (8.096+/-1.464)mm in height. The average value of exophthalmos was (15.002+/-1.922)mm. There was a significant relationship(P>0.05) in the average size between the width and height in palpebral fissure. Also, there was a significant relationship(P>0.05) in the average size between the palpebral fissure width and exophthalmos. On the other hand, there was a significant relationship(P>0.01) in the average size of palpebral fissure height and exophthalmos. Conclusions: In this study, these results suggested that the palpebral fissure and exophthalmos had a significant relationship in the average value of size in Korean adult women population.

Purpose. To analysis the refractive error in 7-9 year-old Korea children. Methods. From July 2013 to June 2014, two hundred eighty two subjects were performed in refraction test using the Auto-Refractometry. Results. The refractive error by spherical equivalent among all subjects was myopia 47.58%, emmetropia 42.35%, astigmatism 32.33%, and hyperopia 8.76%. Myopia was more common in female than males although the difference was not statically significant. The axis of astigmatism was with the rule in 65%, against the rule in 31.5%, and oblique in 3.5% There was a statistical significance between 7 year and 9 year of male in the spherical equivalent power(p=0.010). Also there was a statistical significance between 7 years and 9 years of female in the spherical equivalent power(p=0.036). However, there was not a statistical significance between male and female in spherical equivalent power(p>0.5). Conclusions. In this study, myopia was the most common refractive error. On the other hand, The prevalence of the axis of astigmatism was the with- the- rule. The spherical equivalent of refractive error was similar results between male and female. However The refractive error was different style with aging. these data suggested that the analysis of the refractive error at young children can provide the information of useful diagnosis for the correction of visual acuity.
