Irritant skin reactions can be evaluated by several techniques. Using different scores for the degree of erythema, edema, scaling and fissuring is the time-honored approach but implies t,he disadventagrs of lacking objectivity and pararretric properties. This paper describes the objective nteasurement of irritant. skin responses to various concentrations of Sodium Lauryl Sulfate(SLS) and Ethanol by a color reflectance meter(Chroma Meter) and compares with visual scoring The results are summarized as follows : 1. Pretreatment assessments by a Chroma Meter on normal forearm area showed an average score of 7.70+1.53 for Chroma Meter value a*(rediies:; score). 2. Skin responses to SLS in various concentrations of 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 7.5% under occlusion for 24 hours were assessed by visual scoring system. They are measured 0.56+1.10, 0.74+1.29, 1.19 1.36, 2.11+1.69, 2.19+1.91, 2.56+1.50 2.81+2.16 respectively. 3. Skin responses to SLS in various concentrations of 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 7.5% under occlusion for 24 hour were assessed by a Chroma Meter valu a*(redness score). They are measured 8.29+1.98, 8.37+2.47, 9.31+2.27, 10.34+2.97, 10.35+3.18, 10.51+2.47, 11.61+3.45 respectively. 4. Skin responses to Ethanol in various concentrations were nearly negligible. 5. We have demonstrated there is a highly significant correlation between skin redness measured by the Chroma Meter and visually assessed erypthma(p<0.0001). It yields reproducible, objective, quantitative measurements of iryhema that parallel the subjective visual assessments.

Seventeen patients with classical rheumatoid arthritis have been treated with gold sodium thiomalate(G.S.T) injection and followed up for 1.7 years on average. The results obtained are as follows: 1. Clinical improvement was obtained in 12(70.3%) out of 17 cases, but only in 5 cases(29.3%) marked and persisting improvement was obtained. Such improvement was first noticed when the total dose of the gold sodium thiomalate reached 500mg or more, and also noticed about 10 weeks after initiation of G.S.T therapy. 2. Changes in laboratory parameters such as hemoglobin, hematocrit, eosinophilia, titers of rheumatoid factor and C-reactive protein, and proteinuria began to appear at the time of the clinical improvement. 3. Adverse reaction consisted mostly of mucocutaneous lesions. The main causes of drop-out during therapy also are severe skin rashes and pruritus. Most of the adverse reactions appeared when the total dose of G.S.T. administered reached over 500mg. In two severe cases skin rashes terminated the gold therapy. Our findings suggest, because of high incidence of adverse reaction during G.S.T therapy, repeated careful clinical and laboratory examination of the patient are mandatory especially when the total dose of G.S.T is reached 500mg. In spite of the well documented reports of the maintenance gold therapy for rheumatoid arthritis it is felt that the maintenance gold therapy should be studied further before it can be safely used as a routine in daily rheumatology practice because of its toxicity.

The scleral fixation of a posterior chamber intraocular lens is known to be a technique for managing cataract, aphakia, lens dislocation, pseudophakic bullous keratopathy with incomplete zonular or capsular support. We performed a retrospective review of longterm results and complications of 86 patients(103 eyes) who had a minimum of 12 months follow-up after scleral fixation of a posterior chamber intraocular lenses. At the last examination, mean postoperative corrected visual acuity is 0.7 +/- 0.28 and 62 eyes(57.4%) had a vision of 0.8 or better. Especially in aphakia, postoperative corrected visual acuity was significantly improved. The complications related to scleral fixation were exposed scleral fixation suture, glaucoma, cystoid macular edema, subluxation of intraocular lenses, retinal detachment, herpetic keratitis, vitreous hemorrhage and vitreous opacity. The other factors influenced on visual acuity were age-related macular degeneration, optic atrophy, diabetic retinopathy and clinical significant macular edema, and corneal opacity. Though these longterm results suggest that overall prognosis for visual acuity is quite good, careful assessment preoperatively and proper management are important.

Congenital coloboma which is characterized by an absence of a part of normal ocular tissues involving iris, lens, ciliary body, choroid, and optic nerve. And choroidal coloboma is a rare disease in which there are defects of a part or all parts of choroid and retinal pigment epithelium. Retinal detachment has been reported in 23-42% of the patients with choroidal coloboma, and when retinal breaks are within the area of coloboma, conventional scleral buckling technique has resulted in low rates of anatomic success. We report a case of choroidal coloboma combined by retinal detachment which was treated by pars, plana vitrectomy, fluid-gas exchange, and laser photocoagulation.

Neonatal and Infantile conjunctivitis are common disease in ophthalmologic outpatient department but, a study of causative organisms and antibiotics sensitivity tests are insufficient till now We divided 117 babies(117eyes) having conjunctivitis into neonatal and infantile group who were visited Sung-Ae General Hospital from Jan, 1989 to May, 1990. We performed bacterial culture and antibiotic sensitivity test. The results were as follows; 1) Culture positive rates are 65% in neonates and 87% in infants. There is no sexual difference of ratio. 2) The incidence of isolated organisms is Staphylococcus aureus, Coagulase negative staphylococcus and Streptococcus. 3) Cephalothin is most sensitive antibiotics and Chloramphenicol shows relatively lower sensitivity.

6.Analysis of 137 Pediatric Low Vision Patients.
Journal of the Korean Ophthalmological Society 2001;42(8):1194-1201
PURPOSE: We intended to analyze the characteristics of a pediatric low vision population. METHODS: Among 430 patients who visited our low vision clinic from May 1995 to April 2000, 137 patients(31.9%) aged 15 years or less were reviewed to study epidemiologic characteristics, prescribed aids and required magnification. RESULTS: The percentage of pediatric low vision patients was higher than that of developed countries. Male predominance was found. Optic atrophy(41.6%), congenital cataract(12.4%), macular degeneration and dystrophy(9.5%) were the major causes of low vision in this population. The most commonly prescribed low vision aid was a telescope. For near task, light-gathering magnifiers were prescribed most commonly. The visual acuity was improved significantly at near and far distance after correction with low vision aid. The mean required magnification was 3.5 xand this means that a low magnification was sufficient in the majority of cases. CONCLUSIONS: Early rehabilitation and long-range planning for the low vision child are required because of profound effect of childhood visual impairment.

Recently, antimetabolotes such as 5-fluorouracil and mitomycin have been used successfully to reduce postoperative adhesions in animal models after strabismus surgery.Nine rabbits, 18 eyes, 36 areas were divided into 4 groups. The first group was a control one. The second group was treated with 5-fluorouracil intraoperatively. The third group was treated in the same manner as the second group, followed by subconjunctival injections of 5-fluorouracil from postoperative 7th day. The fourth group was treated with mitomycin C intraoperatively.The thied group(booster group) and the fourth group(mitomycin group) were superior to the others in preventing the postoperative adhesions. There was no statistically significant diference in scar length and adhesion grade between booster group and mitomycin group.This study reveals that the subconjunctival injections of 5-fluorouracil after intraoperative contact may reduce postoperative adhesions in secondary strabismus surgery and may prevent the possible serious complications of mitomycin C, giving the similar effect to potent mitomycin C.

We conducted a retrospective study of 20 penetrating keratoplasty (19patients) for corneal opacity due to herpes simplex keratitis from January 1992 to February 1997 at National Medical Center. We exaniined f requeuey of graft rejection and recurrence of herpetic keratitis after penetrating keratoplasty. The patients were grouped into control & treatinent, group according to the use of antivirial drug after penetrating keratoplasty and we examined the difference in rate of recurrence between two groups. The follow-up period was from 8 months to 68 months, mean follow-up period being 29.6 months. Graft rejection was seen in 3 eyes out of 20 eyes (15.0%) and recurrence was developed 3 eyes out of 20 eyes (15.0%). Recurrent herpetic keratitis developed in 15.4%(2 of 13) of the eyes in control group and 14.3% (1 of 7) of the eyes in treatment group. There was no statistically significant difference in recurrence rate between two groups (p)0.05). Postoperative prophylactic antiviral treatment is not associated with decreased rate of herpes simplex keratitis recurrence.

Journal of the Korean Ophthalmological Society 1998;39(6):1095-1103
The authors have evaluated the effect of topically applied 1% cyclosporine A for four weeks after limbal allograft transplantation for ocular surface stability in severely ocular surface damaged rabbits. A total eleven severely damaged rabbits were subdivided into three groups of four limbal autograft (AUTO), three limbal allograft (ALLO), four limbal allograft with topical application of 1% cyclosporine A five times daily for four weeks (ALLO-C). We examined ocular surface smoothness, clarity, corneal vascularization before surgery and three months after surgery, and classified three grade (success, partial success, failure) according to result. In AUTO, three eyes were success, one eye was failure. In ALLO, one eye showed inferior graft detachment and one eye was success, two eyes were failire. In ALLO-C, no graft detachment detected and one eye was success, two eyes were partial success, one eye was failure. We knew that. ALLO-C show more effective ocular surface stability than ALLO. These result suggest ALLO-C can be used as alternative treatment of AUTO in ocular surface reconstruction. But, rnore study for duration and concentration of cyclosporin A will be need.

10.Clinical Analysis of 100 Low Vision Patients.
Journal of the Korean Ophthalmological Society 1997;38(1):141-148
One-hundred patients with low vison caused by various ophthalmic pathologies were evaluated retrospectively. Ophtic atrophy was the most common etiology for low vision. For the low vision patients, hand-help magnifiers, stand magnifiers, telecopes and spectacle-mounted magnifiers were used as optical low vision aid(LVA)s. Typoscopes, visors, absorptive lenses, reading stands were used as non-optical LVAs. Closed circuit television was used as an electrical LVA. Majority of patients(82%) benefited from being prescribed low vision aids Therefore, it was suggested that all patients having low vision should receive a low vision assessment.
