To investigate recovery, growth, and activity of hepatocyte in primary culture after cell separation, the authors followed up the marker enzyme activities of golgi complex, mitochondria and biologic membrane. Thiamine pyrophosphatase, the marker enzyme of golgi complex, activity approached the level of long term culture at 4th day. Succinate dehydrogenase, the marker enzyme of mitochondria, activity decreased with time, then it maintained constant level after 4th day. Alkaline phosphatase, the marker enzyme of biological membrane, activity increased from 3rd day, and after 5th day it showed strong reaction. These data suggested that hepatocytes were stabilized and recovered normal activity 4 day after cell separation. But the main secretory function was speculated to be reduced in culture.

To know the pattern of visual field (VF) defect of low tension glaucoma (LTG), its diffuse and localized VF defects were compared using the significance values (p-value) of mean deviation (MD) and corrected pattern standard deviation (CPSD), which are calculated with STATPAC in Humphrey Visual Field Analyser. Sixteen eyes of LTG were enrolled and 34 eyes of primary open angle glaucoma (POAG) were used as controls. The degree of VF defects in LTG and POAG was relatively mild with the p-value of MD equal to or greater than 1%. Neither mean MD nor mean CPSD of LTG was significantly different from each of POAG (p > 0.8 and p > 0.2, respectively). Comparing the p-values of MD and CPSD, many patients showed more significant p-value of MD in LTG and POAG (62.5% and 61.8%, respectively). However, relatively more severe defect of CPSD tended to occur more frequently in LTG than in POAG (25% and 5.9%, respectively, chi-square = 4.964, p < 0.09). The relation between p-values of MD and CPSD was not significantly influenced by the intraocular pressure, MD or vertical cup to disc ratio in either LTG or POAG.

Six patients with exfoliation syndrome were seen in our glaucoma clinic. Four patients presented unilateral ocular involvement and the other 2 patients were bilaterally involved. Eight eyes had exfoliation material on the anterior surface of the lens and pupillary border, and 7 eyes exhibited it on the anterior chamber angle. Sampaolesi`s line was detected in 4 eyes. Five patients (6 eyes) of 6 patients (8 eyes) with exfoliation exhbited an elevated intraocular pressure (IOP) exceeding 21 mmHg. Among them, 3 patients (3 eyes) had an extremely high maximum IOP over 47 mmHg, and 2 patients (3 eyes) had a slightly elevated IOP less than 26 mmHg during the follow-up period. Argon laser trabeculoplasty (ALT) was performed twice on each unilateral eye of the 2 patients on whom the inital trabeculectomy failed. However, longterm IOP control after laser treatment was not obtained in either case, which might be due to the extremely high prelaser lOP level, in exoess of 40 mmHg.

We have experienced automated and computerized perimetry using a Humphrey Field Analyzer in our Glaucoma Services. To evaluate its clinical efficacy, we report the results of the Armaly central field screening test in comparison with those of central 30-2 threshold test of the Humphrey Field Analyzer. One hundred fortythree eyes of 83 cases of normotensives, ocular hypertensives and glaucoma patients with open-angle or narrow-angle were enrolled in this study. Fiftyfour out of 61 patients (88.5%) and 73 out of 81 eyes (90.1 %) with visual field defect were detected by the screening test of the Humphrey Field Analyzer. Eight out of 81 eyes (9.9%) with visual field defect detected by the screening test were confirmed as false positive. All points of false positive were solitary, which tended to occur more frequently on superior vusual field. False negative of 8 eyes (12.9%) detected by the screening test were confirmed by the threshold test. The point of false negative was more frequent on superior field and showed to locate more peripherally from the fixation point. There was no significant difference in either central sensitivity or age of the false ring.

The major forms of amyloidosis affecting the eye are primary systemic and localized amyloidosis. Primary Amyloidosis localized to the conjuctiva is relatively rare, especially involved to bulbar conjunctiva and corn eo scleral limbus and is consiccered to be in the differential diagnosis of other conjunctival diseases. We diagnosed a amyloidosis in which the biopsy from the superior bulbar conjunctiva and superior cornea of the left eye of 68-year-old woman showed histopathologic findings of amyloidosis. There were no evidences of amyloid deposit except conJuntiva and cornea on physical and other systemic examination, including immunelectrophoresis, and cornea on physical and other systemic examination, including immunelectrophoresis, and no evidences of underlying disease that can cause amyloidosis. So we concluded that it was primary localized amyloidosis of bulbar conjunctiva and cotnea.

Aqueous flare, the scattering of light by the Tyndall phenomenon, have been applied for the assessment of aqueous protein by the ophthalmologists. Since the intensity of flare ultimately reflects the severity of ocular inflammation. Laser flare-cell meter was developed to determine protein concentration and number of cells in the aqueous with non-invasive technique. The principle of evaluation was similar to that of slit-lamp examination in the viewpoint of scattering of light. The significant linear correlation was observed between the values of concentration for protein and photon counts, in the range from 5mg/100ml to 2,500ml/100ml in boine serum albumin (BSA) and from 5mg/100ml to 1,000mg/100ml in human gamma globulin (HGG), the valuses of HGG was three times higher than those of BSA in the same concentration. In experiments for WBC, RBC and latex particles with diameter of 2.95 micrometer, although somewhat differences was observed according to the sort of cells, significant linear correlation was shown between the number of detected peaks and that of cells.

The intraocular pressure (IOP) of glaucomatocyclitic crisis with the attack fell 50.3%, from 37.8 +/- 8.2 mmHg to 18.8 +/- 4.8 mmHg, 4 hours after instillation of 1% apraclonidine. Glaucomatocyclitic crisis showed a more significant hypotensive response to 1% apraclonidine than primary open-angle glaucoma (24.8%, from 43. 1 +/- 8.1 mmHg to 32.4 +/- 7.5 mmHg after 4 hours). The intraocular pressure decrease percentage was similar regardless of the initial level of intraocular pressure. Clinically significant changes in mean systolic and diastolic blood pressures, were not observed, however, a mild decrease in the pulse rate was noted. And the local mydriatic effect on the pupillary diameter was significant. Apraclonidine, 1% might be newly indicated to control the IOP rise of glaucomatocyclitic crisis. Further studies on the possible mechanism of the prostaglandin mediated hypotensive effect of 1% apraclonidine are suggested.

To evaluate the clinical usefulness of a newly developed beta-one selective blocker. Betaxolol hydrochloride(Betoptice(R)), seven patients(14 eyes) with primary open-angle glaucoma who were instilled twice a day with a drop of 0.5% Betoptic were enrolled in this study. Intraocular pressure(IOP), systolic and diastolic blood pressure, pulse rate and pupil size were measured with the evaluation on the local adverse reaction before and after the Betoptic treatment of 1, 2, 4, 8 and 12 weeks. The following results were obtained: 1. Significant reduction of IOP was noted at all intervals examined after the treatment of 0.5% Betoptic and it had the additive effect on pilocarpine. 2. The systemic side reaction of Betoptic on either pulse rate or blood pressure was not significant and pupil size was not changed by Betoptic. 3. The local transient and mild stinging sensation with tearing was followed after the instillation of 0.5% Betoptic eye solution.

The first comprehensive clinical description of exfoliation syndrome was published by Vogt. The appearance is described as a deposition of white granular fluffy material on the anterior lens surface, pupil margin, zonule, ciliary body and anterior chamber angle, and floating free in the aqueous. At past, this syndrome was thought to be rare outside of the Scandinavian countries, but the relatively high prevalence has been noted in many other countries outside of Scandinavia. The clinical significance of this syndrome is high frequency of glaucoma. Six cases in this report illustrate some of typical clinical features of exfoliation syndrome. The purpose of this study is to concentrate our attention upon the presence of this syndrome in Korea.
