  • The sense of vision is the primary means by which we gather information from our surroundings, and vision loss, therefore, severely compromises the life of the affected individuals, their families, and society. Loss of vision becomes more frequent with age, and diabetic retinopathy, age-related macular degeneration, cataracts, and glaucoma are the major causes of vision impairment. To find active pharmacological compounds that might prevent or ameliorate the vision-threatening eye diseases, numerous studies have been performed, and some botanical compounds, including those extracted from ginseng, have been shown to possess beneficial effects in the treatment or prevention of common ocular diseases. In this review, we summarize the recent reports investigating the therapeutic effects of ginseng and ginsenosides on diverse ocular diseases and discuss their therapeutic potential.

  • Xanthoma is a relatively rare soft tissue lesion on the Achilles tendon and is usually associated with hyperlipidemia (lipid metabolism abnormality), mental retardation, cataract and atherosclerotic disease. We report on a case of normolipidemic bilateral Achilles tendon xanthoma without any notable cause. We herein describe the case where we achieved a satisfactory result by subtotal resection.

  • Oxidative mechanisms are thought to have a major role in cataract formation and diabetic complications. Antioxidant enzymes play an essential role in the antioxidant system of the cells that work to maintain low steady-state concentrations of the reactive oxygen species. When HLE-B3 cells, a human lens cell line were exposed to 50-100 mM glucose for 3 days, decrease of viability, inactivation of antioxidant enzymes, and modulation of cellular redox status were observed. Significant increase of cellular oxidative damage reflected by lipid peroxidation and DNA damage were also found. The glycation-mediated inactivation of antioxidant enzymes may result in the perturbation of cellular antioxidant defense mechanisms and subsequently lead to a pro-oxidant condition and may contribute to various pathologies associated with the long term complications of diabetes.

  • An 8-month-old female rabbit was presented with a white intraocular mass in the right eye. Slit-lamp biomicroscopy showed a white mass behind the iris, accompanied by rubeosis iridis and aqueous flare. Ocular B-scan ultrasonography revealed hyperechoic material within the anterior chamber connected with cataractous lens in the right eye. Signs deteriorated despite treatment, and enucleation was performed. Histopathologically, phacoclastic endophthalmitis due to Encephalitozoon cuniculi infection was confirmed. This was the first report of a client-owned rabbit affected with E. cuniculi-associated phacoclastic uveitis. Serological detection of anti-E. cuniculi antibodies should be considered to prevent potential zoonotic risk.

  • Inherited metabolic disorders (IMD) are a large group of rare disorders affecting normal biochemical pathways. The ophthalmic involvement can be very varied affecting any part of the eye, including abnormalities of cornea, lens dislocation and cataracts, retina and the optic nerve, and extraocular muscles. Eye disorders can be initial symptoms of some IMD and can be clue for diagnosis of IMD. However, eye disorders can evolve later in the natural history of an already diagnosed metabolic disorder. Awareness of IMDs is important to facilitate early diagnosis and in some cases instigate early treatment if a patient presents with eye involvement suggestive of a metabolic disorder. Ophthalmological interventions are also an important component of the multisystem holistic approach to treating patients with metabolic disorders.

  • After establishment of methodology for the separation and quantitation of optical isomer existed in food or biomaterial, the relationship between isomer and nutrient or biological sample was investigated. The optical isomers of standard amino acids and free amino acids were quantitized and the protein was assayed from the Korean bean, pasted bean, soy sauce, gochujang, powderd milk and cataract followed by hydrolysis and dervatization with TFA-IPA for GLC analysis with chirasil val column. Amino acids showing the racemization were alanine, aspartic acid, glutamic acid and phenyl alanine. The most convenient amino acid deducing age and biological activity was aspartic acid. Glutamic acid and phenyl alanine have shown poor resolution with less racemization. The ratio of d-form amino acids was 3~6% for home made pasted bean, about 3% for commerical pasted bean, 2~4% for soy sauce, about 1% for bean, 1~2% for cataract, 1.0~1.5% for powdered milk. The racemization during fermentation process was significant.

  • Purpose: Lawn trimmers are widely used to cut the weeds around graves in South Korea, but they can cause ocular injury. We investigate at the emergency room the incidence and the clinical features of ocular trauma induced by lawn trimmers. Methods:The authors analyzed 106 patients who visited Konyang University Hospital's emergency room from March 1, 2007, to October 31, 2011, because of ocular trauma caused by a lawn trimmer. Patients were sorted into two groups, severe ocular injury and mild ocular injury. Results: Over a 5-year period, 106 patients with ocular trauma caused by a lawn trimmer underwent clinical study. Most of the patient (103 patients) were males, and the average age of the patients was $51.75{\pm}11.66$ years. The incidence of ocular trauma peaked in the sixth decade of life. Most injuries occurred between July and September. Severe ocular injury developed in 46.2% of all patients. As age increased, so did the severity of the ocular injury. The impacting object was a small stone in 43.4% of all patients. Nobody wore protective gear. The most common diagnosis were corneal abrasion, followed by intraocular foreign body, corneal laceration, and sclera laceration. Fifty-four patients were followed up, and thirty-six patients of them had severe injury. The most common complication was a traumatic cataract. Conclusion: Ocular trauma induced by a lawn trimmer is more severe than general ocular trauma. We suggest that everyone using a lawn trimmer should wear protective gear and follow safety guidelines.

  • Purpose: In this study, we studied ocular disease by age in Ulsan. Methods: We checked medical record of 300 patients who visited eye clinic in Ulsan. Results: The main ocular disease on the age of 10 was keratitis, that of 20 was dry eye syndrome & keratitis, that of 30 was chalazion & conjunctivitis, that of 40~50 was conjunctivitis, that of 60 was conjunctivitis & cataract. Conclusions: The main cause of ocular disease of 10~20's are unsuitable wear of contact lenses & long-time use of smart phone as well as computer. That of 30~50's are allergic conjunctivitis and chemical material reaction as well as other several factors. Especially, attack rate of conjunctivitis of 30~50's is higher than city because of industrial area (Ulsan). The main cause of ocular disease in 50~60's is a kind of senility. Therefore, based on the results of this study, it could be used the basic data of education on ocular disease prevention in Ulsan.
