Objective : This experimental study was performed to investigate the effect of Jinpi-san on Staphylococcus aureus(S. aureus) and Staphylococcus epidermidis(S. epidermidis) that induce keratitis. Methods : Minimal inhibitory concentration(MIC) was measured by dropping to $50{\mu}l$ according to density Jinpi-san(100%, 10%, 1%, 0.1 %). Anti-bacterial potency was measured by the size of inhibition zone with change of volume. Results : 1. MIC on S. aureus in Jinpi-san was $40{\mu}l$ undiluted solution. 2. MIC on S. epidermidis in Jinpi-san was $20{\mu}l$ undiluted solution. Conclusions : These results indicate that Jinpi-san can be used to cure S. aureus, S. epidermidis that induce eye disease(keratitis). If further study is performed, the use of eye drops will be valuable and beneficial in the clinical medicines.

Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散) have been as eye washes of inflammatory eye disease in the oriental medicine. Especially Jinpisan(秦皮散) has been used for the disease which is similar to Peudomonas aeruginisa keratitis. This research was attempted to investigate the effect of Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散), on Peudoronas aeruginisa keratitis. Pseudomonas aeruginosa keratitis causes a deep rapid intense ulceration which often leads to perforation of the cornea within 48 hours. In this research, we induced keratits in the rabbits by inoculating Pesudomonas aeruginosa(9027) and observed the effect on the keratitis and the irritation against the external eye. Also we mesured the minimum inhibitory consentration(MIC) of Coptidis Rhizoma, Fraxini Cortex, Jinpisan(秦皮散) by agar diliution method and the anti-bacterial activites by disk method. The tested bacteria were as follows : a) Pseudomonas aeruginosa (9027), b) Streptococcus pneumoniae(6303), c) Staphylococcus epidermidis(12228), d) Staphylococcus aureus(6538P). The results were as follows ; 1. The groups which were applied eye washes of Fraxini Cortex, Jinpisan reavealed a significant effect, but the group applied eye wash of Coptidis Rhizoma reveaded no effect on Pseudomonas aeruginosa keratitis. 2. Applying eye washes of Coptidis Rhizoma, Fraxini Cortex, Jinisan revealed an irritation against external eyes. 3. Coptidis Rhizoma showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylucoccus aureus by agar diliution method 4. Coptidis Rhizoma showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by disk method. 5. Fraxini Cortex showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by agar diliution method 6. Fraxini Cortex showed an anti-bacterial activity on Pseudomonas aeruginosa, Sireptococcus pneumoniae, Staphylococcus epidermidis, Staphy1ococcus aureus by disk method. 7. Jinpisan showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by agar diliution method. 8. Jinpisan showed an anti-bacterial activity on Pseudomonas aeruginosa, Streptococcus pneumoniae, Staphylococcus epidermidis, Staphylococcus aureus by disk method. According to the above results, Fraxini Cortex, Jinpisan(秦皮散) are recognized to have an effective treatment on the Pesudomonas aeruginosa keratitis, so this experiment is thought to be a basic ingredient in proving the effect of Fraxini Cortex, Jinpisan which is applied many in documents and clinical medicine. In the comparison of anti-bacterial activity and results of treatment on the Pesudomonas aeruginosa keratitis, Jinpisan(秦皮散) was more effective than Coptidis Rhizoma, Fraxini Cortex.

A 4-year-old Chihuahua dog was referred for bilateral corneal ulcers. Slightly raised white fluorescein-positive plaque-like corneal lesions in both eyes appeared as intense hyperreflective areas with posterior shadowing on optical coherence tomography (OCT). Based on corneal cytology and culture, Candida albicans-induced fungal keratitis was diagnosed. Despite treatment, on OCT, endothelial plaques, increased stromal infiltration thickness, vertical shapes of the ulcer edge, and necrotic stromal space were judged to be aggravation of the disease, and surgery was performed. Conjunctival grafting surgery with topical 1% voriconazole effectively resolved fungal keratitis. OCT can provide detailed and objective information related to the disease prognosis.

Methods : After administering various herbal eye drops on Staphylococcus epidermidis, I measured MIC and the size of inhibition zone. MIC was measured by dropping from 20 to $50{\mu}{\ell}$ according to density. Anti-bacterial potency was measured by the size of inhibition zone with change of volume under 2 days culture condition. Also continuous anti-bacterial potency of herbal eye drops was measured by the size of inhibition zone according to 2 days and 6 days culture each under the $50{\mu}{\ell}$ condition. Results : 1. MIC on Staphylococcus epidermidis in Sean-tang, Jinpi-san was 1%, $50{\mu}{\ell}$ 2. MIC on Staphylococcus epidermidis in Tangpo-san, Coptidis rhizoma was 10%, $50{\mu}{\ell}$ 3. MIC on Staphylococcus epidermidis in Cravit was 0.1%, $20{\mu}{\ell}$. 4. Under the 2 days culture condition, the size of inhibition zone on Staphylococcus epidermidis by volume for Sean-tang was 10.0mm in $50{\mu}{\ell}$, Jinpi-san was 16.0mm in $50{\mu}{\ell}$, Tangpo-san was 17.5mm in $50{\mu}{\ell}$, Coptidis rhizoma was 31.0mm in $50{\mu}{\ell}$ and Cravit was 34mm in $50{\mu}{\ell}$, showed the highest anti-bacterial potency. 5. Under the $50{\mu}{\ell}$ condition, the size of inhibition zone on Staphylococcus epidermidis by 2 and 6 culture days for Sean-tang was 47.5mm in 6days, Jinpi-san was 36.0mm in 6days, Tangpo-san was 45.0mm in 6 days and Cravit was 48.0mm in 6 days, which showed the highest anti-bacterial potency. 6. Under the $50{\mu}{\ell}$ culture condition, the size of inhibition zone on Staphylococcus epidermidis by 2 and 6 culture days for Coptidis rhizoma was 31.0mm in 2 days and 6 days, which showed the same anti-bacteria1 potency. Conclusions : The present author think that Herbe-medicine used for eye disease can be used to cure Staphylococcus epidermidis keratitis and if further study is performed, the use of the Herbe-medicine used for eye disease will be valuable and beneficial in the clinical medicines.

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.

This study investigated the status of soft contact lens wear in college students. The results were as follows: 1. The most prevalent age of initial contact lens wear was 19 years or 20 years, with an age distribution in females from as early as 10 years to 20 years. 2. For almost all subjects, the test clinic for the contact lens wear assessment and purchase of the contact lenses was an optical shop. 3. The main advantage for most male subjects was use for sports, whereas most female subjects used contact lenses for cosmetic reasons. 4. The most common side-effects experienced due to contact lens wear were red eye, foreign body sensation, and eye pain. 5. The most frequently reported eye disease caused by contact lens wear was conjunctivitis, with only few subjects experiencing keratitis. 6. Following treatment for the side effects of contact lens wear, most subjects hoped to re-use the previous contact lenses, some subjects wanted to change to new contact lenses, and others subjects refused further contact lens wear.

A 6-year-old spayed female Persian cat presented with a 3-month history of recurrent ulcerative keratitis with noticeable opacification and vascularization of the right cornea. The lesion was nonresponsive to topical antibiotics and to nonsteroidal anti-inflammatory drugs. Ophthalmic examination showed signs of ocular discomfort, such as epiphora and blepharospasm, in the right eye. Biomicroscopic examination revealed an irregular, edematous, vascularized mass with pink to white tissue on the entire cornea and mild conjunctivitis. A tentative diagnosis of feline proliferative eosinophilic keratitis (FPEK) was made on the basis of clinical appearance. Cytologic examination of the cornea showed a mixture of numerous eosinophils and mast cells, which confirmed the original diagnosis of FPEK. The cat was treated with a topical antibiotic-corticosteroid combination, cyclosporine ointment, trifluridine eye drops, and oral Llysine. The clinical signs improved remarkably 18 days after the cat was first examined. The short-term use of corticosteroids and long-term use of cyclosporine and an anti-viral agent resolved the lesion without recurrence of the disease for 1 year.

Disposable contact lenses, which are one type of soft contact lenses, provide convenience in use, but also cause various ocular infectious diseases. Microorganisms that cause eye diseases include Acanthamoeba, bacteria, Fungi, and so on. It is impossible to prevent microorganism contamination completely due to the use of hands as wearing contact lenses. The contamination by various microorganisms leads to infectious keratitis, but it is not well known for the exact microorganisms that affect the disease. For this reason, to identify the microorganisms, two groups that are commonly used for disinfection of lenses were divided: normal saline solution and multiple purpose solution. Using these solutions the degree of microorganism contamination was observed according to the days of 1, 3, 5, 10, and 15. Twenty students by two groups from Ophthalmic Optics department at D college in Daegu Metropolitan city participated in the experiment after their ocular health conditions were checked. During they wore one-day disposable lenses for 1, 3, 5, 10, and 15 days, bacteria were cultured in media. The results, which were Gram stained by selecting the cultured colonies, show as followings: Gram positive cocci 33%, Gram-negative cocci 2%, Gram positive bacilli 34%, and the Gram negative bacilli 31%, respectively. As for the identification of potential pathogens, VITEK system and API kit methods were used. Keratitis caused by bacteria known as Staphylococcus aureus, Pseudomonas aeruginosa were detected as a result of wearing contact lenses. This study examined the distribution of bacteria as wearing one-day disposable contact lenses and pathogenic bacteria according to the duration of wearing them. In conclusion, the importance of hygiene when using contact lenses is suggested.
