The Epidemiological study of glaucoma in Korean is essential because the prevalence and distribution of glaucoma can be different among race and country. We surveyed the prevalence and distribution of glaucoma in Korean careerrnen aged 20 years or older who visited Yongdong Severance Hospital to undergo a regular physical examination during the year of 1992 and the total number of subjects examined was 4959 adults. A mainstay of the screening consisted of applanation tonometry and direct ophthalmoscopy, followed by automatic perimetry as a recall examination. Patients with suspected abnormalities in either the IOP >or=22mmHg or the optic disc findings such as high cup/disc ratio (>or=0.7) were referred for recall examination as the second stage of the visual field test. Overall prevalence of glaucoma obtained was 2.04% (101 patients) and the most common type of glaucoma was low tension glaucoma, 1.71% (85 patients). The prevalence of glaucoma increase with aging especially in low tension glaucoma.

Ovarian mature cystic teratoma containing benign prostatic tissue is rare and only 11 cases have been reported in the literature to date. We report a case of mature cystic teratoma of the ovary containing prostatic tissue. A 23-year-old female patient came to our hospital complaining of irregular menstruation for 3 months. Her menarche had occurred when she was 13 years old. The patient showed no evidence of virilization nor of endocrinopathy. A goose-egg-sized mass was palpable in the left lower abdomen on physical examination. Ultrasonography revealed a cystic ovarian mass with internal echogenecity. Microscopic finding was consistent with that of usual mature cystic teratoma except for a 1.5 cm focus of prostatic and bladder tissues. Prostatic tissue demonstrated strong immunoreactivity for prostatic specific antigen (PSA), prostatic alkaline phosphatase (PAP) and cytokeratin 7. Basal cells of the prostate glands were positive for high molecular weight cytokeratin (34betaE12). Although ovarian mature cystic teratoma containing prostatic tissue has been reported as a rare occurrence, a careful examination with immunohistochemical staining may increase the detection of prostatic tissue in mature cystic teratoma of the ovary.

Measurement of the depth and angle of the anterior chamber can provide valuable information for the diagnosis, treatment and prognosis of angle closure glaucoma. We measured the depth and angle of the peripheral anterior chamber in the normal and the angle closure glaucoma eyes by utilizing ultrasonographic biomicroscopy. We also measured the 4 directions of the depth and angle of the peripheral anterior chamber and iris thickness before and after dilation in the normal eyes. The mean depth and angle of the peripheral anterior chamber were 421 +/- 73 micro meter, 30.46 +/- 6.49 degree in the normal eyes and 294 +/- 25 micro meter, 29.12 +/- 3.75 degree in the angle closure glaucoma eyes respectively. The differences of the depth and angle of the peripheral anterior chamber between the two groups were statistically significant(P<0.05, respectively). The depth and angle of the peripheral anterior chamber significantly increased after dilation in the normal eyes(P<0.05, respectively). The thickness of the iris was 421 +/- 54 micro meter at the iris root site, 509 +/- 57 micro meter in at the middle site and 582 +/- 74 micro meter at the pupillary margin site.

Early detection of glaucoma by mass screening is the most practical approach for prevention of blindness. An epidemIOlogical study gives the most essential information on prevalence an distribution of the disease in relation to diverse background factors. But, before now, an epidemiological study for glaucoma has not been carried out in Korea. Our glaucoma survey was conducted in the health examination center of Yongdong Severance hospital during 1990 and 1991. The total numbers of subjects examined was 4424 persons aged 30 years or older. A mainstay of the screening consisted of applanation tonometry and fundus photography with a non-mydriatic camera, followed by automated perimetry as a recall examination. Overall prevalences of glaucoma obtained were primary open angle glaucoma 0.23% (10 patients), low tension glaucoma 2.04% (108 patients), and ocular hypertension 0.23% (10 patients). The mean lOP obtained with applanation tonometry was 14.04 +/- 2.99 mmHg for men and 14,07 +/- 2.67 mmHg for women. In additon, our data have pointed out that the lOP in different ages tends to be constant, whereas prevalences of glaucoma and low tension glaucoma increase with aging.

It was previously reported that sudden loss of central vision and small residual fields in advanced glaucomatous eyes after filtering surgery. This study was undertaken to assess the risk of sudden wipe-out phenomenon on 57 eyes of advanced glaucomatous patients who could be followed up at least 8 weeks after filterlng surgery. The eyes were classified into three categones according to the seventy of visual field loss, evaluated with Humphrey computerized visual field analyzer and Goldmann perimetry using target with I-4-e. Sudden wipe-out phenomenon was divided into absolute and relative. The former was sudden complete loss of central vision immediately after filtering surgery. The latter was visual acuity decreasing 2 or more lines in Snellen visual acuity chart compared with before surgery or obvious progress1on of visual field defect at the t1me of 8 to 1O weeks after surgery However there were no absolute and relative sudden wipe-out phenomenon in our study. In the light of our experiences, it is concluded that filtering surgery can be performed with caution in advanced glaucomatous eye whenever it is indicated.

Mitomycin-C is known to delay wound healing and it may have influence upon the post operative astigmatism changes. We calculated the postoperative induced astigmatism of patients who underwent trabeculectomy or triple procedures with or without the use of mitomycin-C. And the vector analysis method was used. To compare the induced astigmatism between the groups we calculated the induced astigmatism corresponding to the 180degree axis. The patients who underwent triple procedure without and with mitomycin-C showed a mean induced astigmatism of -4.50D, -1.81D, respectively, after 7 days(p<0.05) and -0.13D, 1.73D, respectively, after 12 months (p<0.05). Those who underwent trabeculectomy without mitomycin-C and with mitomycin-C showed a mean induced astigmatism of -2.63D, -1.01D, respectively, after 1 month(p<0.05) and -1.42D, 0.34D, respectively, after 12 months(p<0.05). The use of mitomycin-C reduces the total amount of astigmatism in trabeculectomy patients. However, in the triple procedure patients it increases the total amount of astigmatism. The entire amount of against the rule astigmatic change was similar between the mitomycin-C applied group and non-applied group. The astigmatic shift of the group without mitomycin-C, reached a plateau after 3 months. However, the other group showed continuous against the rule shift until 12 months.

The anterior chamber depth is important in diagnosis and treatment of glaucoma, thus the research of the anterior chamber depth would help the understanding of angle closure glaucoma. Then the estimation of anterior chamber depth might help the diagnosis of certain cases of glaucoma. It has been reported by other authors in Korea, but there were not enough subjects to see the correlation between age and the anterior chamber depth. The purpose of this study was to measure the variation of the anterior chamber depth in relation to the normal aging process. The anterior chamber depth was measured in 2,524 eyes of normal subjects aged 20 years or older who visited our hospital to receive a health examination. Measurements of the anterior chamber depth were carried out conviniently with the Haag-Streit pachometer. Intraocular pressures were measured with the Pulsair non-contact tonometer, and the refractive errors of each subject were divided into hyperopia, emmetropia, and myopia. These data were analyzed statistically by Student's t-test. Female subjects had a smaller measurement for anterior chamber depth than male. The average anterior chamber depth of the emmetropes was smaller than that of the my opes and larger than that of the hyperopes. It was found that the anterior chamber depth decreased with age(0.015mm/year). The anterior chamber depth seemed not to be correlated with the intraocular pressure.

To find the factors that affect on the success rate of the trabeculectomy, we investigated 208 eyes of 158 patients with various types of glaucoma which had undergone trabeculectomy. The patients were followed up at least 3 month postoperatively. The criteria of success was maintenance of postoperative IOP below 21 mmHg. The total success rate was 89.4%. In young patients, the success rate was lower than that of older ones. The success rate of open angle glaucoma, acute angle closure glaucoma and chronic angle closure glaucoma were higher than that of congenital glaucoma and secondary glaucoma. Recently performed operation demonstrated higher success rate. The type of conjunctival flap, scleral flap and use of 5-fluorouracil were independent factors that affect on the success rate.
