Mucormycosis is a fungal disease in which normal saphrophytic molds produce an acute and often rapidly fatal infection. Patients with orbital mucormycosis commonly present with abrupt visual loss, orbital pain and facial hypoaethesia. In our case, mucormycosis was confirmed by histopathological examination and it was mainly treated with daily intravenous amphotericin B for 42 days. As medical treatment was successful, no orbital exenteration has been necessitated.

PURPOSE: The purpose of this paper is to discuss the characteristic CT and MR findings in persistent hyperplastic primary vitreous(PHPV) and to compare the detectability of those findings in each modality. MATERIALS AND METHODS: We retrospectively evaluated CT and MR findings in 32 patients with PHPV. Twenty-five patients had CT, 13 patients had MR, and 6 patients had both CT and MR. RESULTS: Major findings of PHPV in 32 patients on both imaging modalities were lens deformity(78%), shallow anterior chamber(72%), heterogeneous vitreous opacity(72%), enhancing hyaloid artery or remnant of fibrotic hand(69%), and microophthalmos(67%). Minor findings were retinal detachment(22%), and vitreous hemorrhage(6%). In MRI, lens deformity(92%) and shallow anterior chamber(85%) were detected most commonly whereas in CT, opaque vitreous(80%) was the most common finding. Findings of enhancing hyaloid vessel or remnant of fibrotic band, considered characteristic of PHPV, were more commonly detectable in MR (85%) than CT(52%). CONCLUSION: Characteristic MR and CT findings of PHPV were lena deformity, shallow anterior chanber, heterogeneons vitreons opacity, enhanciny hgalind artery or remnant fibrotic band, and microphthalmos. MR seemed to be more useful than CT in detecting Globe pathology.

Nd-YAG laser is known as a safe and effective treatment for posterior capsular opacity after cataract surgery. We studied the ocular complications after Nd-YAG laser treatment in uveitis patients. From January 1991 to December 1996, we retrospectively investigated the complications of uveitis in 22 persons(25 eyes) after Nd-YAG laser posterior capsulotomy, and also investigated that of nonuveitis in 563 persons(635 eyes) as a control group. The uveitis cases consisted of six anterior uveitis, eight intermediate uveitis, seven Behcet`s syndromes, three panuveitis, and one posterior uveitis. In the uveitis group, the complications(18 eyes) consisted of three retinal detachments, one giant retinal tear, three glaucoma, two aggravations of uveitis, two vitreous opacities, one retinal emorrhage, one proliferative vitreoretinopathy, one hyphema, and four transient high intraocular pressures(IOP), and in the control group, it consisted of two subluxations of intraocular lens(IOL), three glaucomas, one retinal tear, three transient high IOPs, two vitreous opacities, two retinal hemorrhages, three macular holes, two retinal detachments, and five cystoid macular edemas. From our experience, the incidence of complications after Nd-YAG laser posterior capsulotomy in uveitis was higher than that in nonuveitis. It was also noted that it is necessary to follow up thoroughly the complications after Nd-YAG laser posterior capsulotomy in uveitis patients.

A chemical analysis of subretinal fluid was made in 15 patients (16 eyes) who had undergone retinal detachment surgery from March 1, 1991 to July 31, 1991 at St. Mary's Hospital, Catholic University Medical College. The protein concentration of subretinal fluid ranged from 1.0gm/dl to 7.1gm/dl, and the average protein concentration of subretinal fluid of retinal detachment for 90 days or more showed 5.13 +/- 1.71gm/dl and that of subretinal fluid of retinal detachment for less than 90 days was 2.06 +/- 1.29gm/dl. This revealed increasing tendency of protein concentration in proportion to the duration of detachment (p<.05), and the protein concentration of subretinal fluid did not show any differences according to the size of retinal detachment. Sugar ranged from 32mg/dl to 96mg/dl, and chloride was from 92mEq/L to 126mEq/L. From this study, we found that the protein concentration of subretinal fluid increased in proportion to the duration of retinal detachment. On the contrary, sugar and chloride concentration was not related to the duration of retinal detachment.

7.The Changes of Tear Break-up Time and Schirmer's Test after Photore fractive Keratectomy.
Journal of the Korean Ophthalmological Society 2001;42(2):228-234
Myopic regression and corneal opacity are well known complications after photorefractive keratectomy(PRK)and some clinical reports suggest the postoperative dry eye syndrome make worse corneal opacity. To investigate the changes in tear secretion and tear film stability after excimer laser PRK for myopia we measured tear break-up time(BUT)and the Schirmer's test on 249 eyes of 126 persons ranging from -2 ~ -11 D(mean -5.40 D)at preoperative 1 month, 6 month and 1 year after PRK. The result shows that the Schirmer's test and BUT values are reduced together at 1 month after PRK, but BUT values return to almost normal levels at postoperative 6 months, whereas Schirmer's test values never come back to initial ones regredless of the presence of preoperative dry eye syndrome and refractive error. So we reach an idea that the decrease of tear secretion due to vague corneal sensation rather than the tear film instability from irregular corneal surface effects on the postoperative dry eye syndrome largely. From this results, we propose that artificial tears should be used at least for an year for the eyes after PRK.

To investigate the relationship of the density change of lens nucleus and cortex with anterior chamber depth and lens thickness, we measured the anterior chamber depth, density and length of lens nucleus and cortex of 312 eyes with a Scheimpflug camera. The mean values of density of lens nucleus and cortex were 108.45+/-46.33CCT and 27.74+/-13.76CCT, respectively. The mean values of the thickness for both were 2.85+/-0.54mm and 1.29+/-0.46mm, respectively. The mean value of anterior chamber depth was 2.93+/-0.49mm. The densities of lens nucleus and cortex were increased significantly with aging, but lens thickness and anterior chamber depth were decreased. The value of anterior chamber depth changes and lens thickness changes were more rapid especially in the 5th and 7th decades compared with other groups(P<0.01), and more rapaid in the density group(100~150CCT) than other group in changing densities(P<0.05), and they were highly correlated with anterior cortex, posterior cortex, nucleus in order at each portion of lens. Both anterior chamber depth changes and lens thickness changes were more rapid in the lens cortex than those in the lens nucleus.

To study the frequency of the most common organisms according to culture sites, age, antibiotic sensitivity and resistance, we researched the medical records of the patients for the past 5 years who had ever been treated for infectious ocular disease. Total 19 strains and 226 bacterial organisms were cultured in 207 eyes. Most common organism was staphylococcus(37.6%). The overall percentage of gram-positive organisms showed 61.9% and that of gram-negative 38.1%. According to age, the most common organism was staphylococcus in neonatal period, streptococcus in the age from 1 to 10 and over 60, pseudomonas in the age from 21 to 30 and 41 to 50. The common organisms according to the culture site were staphylococcus in conjunctiva, staphylococcus and streptococcus in punctum, staphylococcus and pseudomonas in cornea, and staphylococcus in vitreous. The antibiotic sensitivity test of gram-positive organisms showed sensitivity more than 90% and rare resistance to ofloxacin and vancomycin. Gramneganisms showed sensitivity more than 80% to ofloxacin and resistance less than 30% to tobramycin. Ofloxacin showed high sensitivity and low resistance to all of the gram-positive and negative organisms. According to culture sites, it was vancomycin in conjunctiva and punctum, ofloxacin in cornea, and ciprofloxacin in vitreous that showed relatively high sensitivity and low resistance. Though it is necessary to culture and test antibiotic sensitivity in treating the ocular disease, it seemed effective as primary therapeutic agents to use appropriate antibiotics based on the clinical findings before the test results are reported. Periodic culturing of causative organisms and testing the antibiotic sensitivities would be helpful in selecting the effective antibiotics for treatment and reducing abuse of antibiotics.

It is very desirable to clarify the situation of fertility, family planning and attitude toward family size of the women residing in the sub-urban slum area because of underprivilege of socio-economiccondition of the residents and negligible health services (especially MCH and family planning) to the people in the area. The study area was selected a slum and primary fixation place of the people immigrated from rural area: Taegu, Dong Ku, Shin Chun Dong, 2 Ka and Taegu, Suh Ku, Ri San Dong, 1 Ka The survey was conducted by family planning workers at Health Center from December 1974 to February 1975. The results were obtained as follows: Thirty-eight percent of residents immigrated from rural area and most of there consist of nuclear family. Average monthly income per family was 38,000 won and 74 percent of them haven't their own houses. Number of pregnancy and live births per womon were 3.8 and 3.0 respectively. The rates of spontaneous and induced abortion to total married women were 9.5% and 36% respectively. Regarding delivery conditions, 86% of deliveries were performed at home and 70% of them were cared by non-professional person or without helpers. Ideal number of children account for 1.58 for sons, 1.08 for. daughters 2.655 for both, but the rate of 2 children regardless sex difference was only 3.4%. The factors influencing to family size were age and educational level of women and economic status of the hosehold. Regarding family planning, the rate of experience of contraception in the past was 48 percent while the rate of present contraception was 24%. Most frequent pregnancy order at the first contraception was 4th and most frequent age group of the women was 35-39 years in the past while the most frequent pregnancy order and the age of women were 3rd and 30-34 years at the first contraception in the present. Average fertility rate per year to total eligible women for 5 years 20.8% indicating somewhat higher than those of oter places. Age specific marital fertility rate showed higher in younger age groups than those of other places, and total fertility rate accounts for 1548.4 showing similar to rural total fertility rate in 1970 and higher than those of other urban areas.
