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.

Olive flounder (Paralichthys olivaceus) is one of the commercial important flatfish species in Korea. The ocular signal transduction pathway is important in newly hatched flounders because it is closely involved in the initial feeding phase thus essential for survival during the juvenile period. However, the study of gene expression during ocular development is incomplete in olive flounder. Therefore we examined the expression analysis of specifically induced genes during the development of the visual system in newly hatched flounders. We searched ocular development-involved gene in the database of expressed sequence tags (ESTs) from olive flounder eye and this gene similar to arrestin with a partial sequence homology. Microscopic observation of retinal formation corresponded with the time of expression of the arrestin gene in the developmental stage. These results suggest that arrestin plays a vital role in the visual signal transduction pathway of the retina during ocular development. The expression of arrestin was strong in the ocular system during the entirety of the development stages. Our findings regarding arrestin have important implications with respect to its biological role and evolution of G-protein coupled receptor (GPCR) signaling in olive flounder. Further studies are required on the GPCR-mediated signaling pathway and to decipher the functional role of arrestin.

Carboplatin intra-arterial chemotherapy(IAC) has an advantage of increased uptake during the first passage of the drugs through tumor capillaries. Although not common, this type of therapy is known to cause neurological complications, myelosuppression, and ototoxicity. However, the incidence of ocular toxicity is reported to be rare. Eleven of our patients with glioma(Grade II Astrocytoma : 3, Grade III Astrocytoma : 1, Grade IV Astrocytoma : 5, Gliofibroma : 1, Oligodendroglioma : 1) underwent IAC regimen with carboplatin($300mg/m^2$) which were administrated after blood-brain barrier disruption. Of there, 3 patients had ocular complications after supra-ophthalmic IAC injection of carboplatin but fully recovered following steroid therapy. Although our results from IAC seem to be favorable for these patients, we suggest that its complications, such as ocular toxicity, need to be carefully considered prior to treatment.

Objectives: This is a case report about the effect of Korean medicine on blepharoptosis and ocular motility disorders that occur with thalamus, midbrain, and cerebellum infarctions. Methods: The patient was treated using Korean medicine such as acupuncture, moxibustion, and herbal medicine (Boyanghwano-tang-gamibang). The change of blepharoptosis was evaluated by measurement of palpebral fissure width (PFW), marginal reflex distance-1 (MRD1), and marginal reflex distance-2 (MRD2). The change inocular motility disorders was evaluated by comparison using photographs of the extraocular movements of the patient. We used the Numeric Rating Scale-11 (NRS-11) of diplopia and dizziness to evaluate the effectiveness of treatment. Results: After treatment, blepharoptosis and ocular motility disorders were improved. The NRS-11 score of dizziness decreased from 10 to 7, and diplopia disappeared after Korean medicine treatment. Conclusions: According to this study, Korean medicine can be effective for treating blepharoptosis and ocular motility disorders in thalamus, midbrain, and cerebellum infarctions.

Centronuclear myopathy (CNM) is a rare congenital myopathy that is pathologically characterized by the centrally located nuclei in most of the muscle fibers. On clinical examination, dynamin 2 (DNM2)-related CNM typically shows distal dominant muscle atrophy, ptosis, ophthalmoplegia, and contracture. The reported cases of CNM in Caucasian studies show a high prevalence rate of early-onset ptosis and ophthalmoplegia and correlated with the severity of the disease. However, Asian reports show a low prevalence and late-onset ocular symptoms in DNM2-related CNM patients. p.R465W is one of the most commonly found mutations in Western countries, and all the cases showed ocular symptoms. The proband and his daughter had no ocular symptoms despite harboring the same p.R465W mutation. This family makes us speculate that ocular symptoms in DNM2-related CNM are influenced by ethnic background. In addition, this is the first familial case of DNM2-related CNM in Korea.

Objectives : The purpose of this study is to analyze effectiveness of herbal medicine treatment on Dry Eye Syndrome. Methods : We analyze medical records of 114 patients who visited Indara oriental medical clinic for dry eye syndrome. Patients were treated with acupuncture and Inmok-tang, and the ocular surface disease index was evaluated before and after treatment. Results : Analysis of 114 medical records showed a significant decrease in the pre-treatment and post-treatment ocular surface disease index, and a statistically significant positive correlation between the duration of Inmok-tang administration and the change in the ocular surface disease index. Conclusions : Herbal medicine treatment with Inmok-tang reduces the Ocular Surface Disease Index, an indicator of subjective symptoms of dry eye syndrome.

다양한 의료진단 자동화 기기들이 개발되고 있으나 대부분 서양의학에 집중되어 있는 현실이고, 한의학의 진단시 자동화 및 정량화를 위한 장치 개발은 미미하다. 한편, 한의학에서의 네가지 진단 방법 중 하나인 망진은 환자의 관형과 찰색을 통해 질병의 유무와 경중을 진단한다. 망진을 시행할 때 얼굴에서 이목구비와 명당 부위의 상태가 특히 중요하다. 본 논문에서는 얼굴 영상으로부터 망진을 위한 얼굴 요소들을 추출하기 위한 방법을 제안하고, 남여 얼굴 영상에 대한 실험을 통해 제안한 방법의 유용성을 보이고자 한다.

일부 눈의 합병증은 콘택트렌즈에 연관된 것에 의해 감염이 관련되어 있다. 특히 눈 합병증의 대부분의 원인은 감염의 여러 경로로 인한 미생물인 것이다. 그러므로 환자는 눈 병의 부작용에 의해서 즉시 콘택트 렌즈 착용을 중단한다. 저자는 실험실에서 미생물을 분석하였다. 이것은 Chryseamonas meningosepticum와 Enterobacter sp.의 혼합된 성장으로서 확인되었다.
