Central Corneal Thickness in Korean Subjects with Primary Angle-Closure Glaucoma

PURPOSE: To compare the central corneal thickness (CCT) in eyes of Korean subjects with primary angle-closure glaucoma (PACG) to other patients with glaucoma and control subjects. METHODS: Medical records of patients who underwent examination for glaucoma and pre-operative examination for cataract surgery between March 2009 and August 2012 in our clinic were reviewed. CCT was compared in normal control eyes, primary open angle glaucoma (POAG) eyes and normal tension glaucoma (NTG) eyes. RESULTS: The mean CCT of POAG eyes was significantly larger than that of normal control eyes, NTG eyes and PACG eyes (p = 0.027, 0.009 and 0.008, respectively). There was no significant difference in mean CCT between normal control eyes, NTG eyes or PACG eyes. CONCLUSIONS: PACG eyes had a CCT similar to that of NTG or normal eyes in Korean subjects.

A Case of Bilateral Central Serous Chorioretinopathy after Blunt Trauma

PURPOSE: To report a case of bilateral central serous chorioretinopathy (CSC) after blunt trauma with rapid remission. CASE SUMMARY: A 44-year-old man visited our clinic after blunt trauma around the right eye. At the first examination, no ocular problem was detected except a periorbital contusion. After one week, the patient complained of visual disturbance in his right eye. Fundus examination showed subretinal fluid in his right eye, and fluorescein angiography (FAG) showed typical smoke-stack pattern leakage, which lead to a diagnosis of CSC. Three days later, the patient complained of visual disturbance in his left eye, which was then also diagnosed as CSC. After 2 more weeks, the subretinal fluid in the right and left eyes had decreased. After 3 weeks, the subretinal fluid was almost completely absorbed in both eyes. CONCLUSIONS: Central serous chorioretinopathy can develop after blunt trauma, especially with a rapid clinical course. Thus, periodic ophthalmologic examination is needed after the first examination for blunt trauma of the eye.

Foveal Shape According to Age and Gender Using Spectral Domain Optical Coherence Tomography

PURPOSE: To compare foveal shapes in Koreans according to age and gender using spectral domain optical coherence tomography (SD-OCT). METHODS: This study included 230 eyes of 115 healthy adults. The subjects were divided into three groups: group 1 (20-39 years of age), group 2 (40-59 years of age) and group 3 (60-79 years of age). Using spectralis OCT, we measured central foveal thickness (CFT), regional maximal retinal thickness (MRT), pit diameter and pit depth and compared the differences between the groups. RESULTS: The MRT of the superior, inferior and nasal sides in group 1 was higher than in groups 2 and 3 (p < 0.05). No significant difference was observed in the MRT of the temporal side. Regarding differences based on age, no significant differences in CFT, pit diameter and pit depth were observed. Regarding differences in gender, the temporal regional MRT of males in group 3 was significantly lower than in group 1 and the pit depth of males in group 1 was significantly higher than in groups 2 and 3. Therefore, differences were observed according to gender. CONCLUSIONS: In the present study, differences in foveal shape were found according to age and gender which should be considered when foveal diseases are evaluated.
