Ocular infection caused by Neisseria gonorrhea produces purulent conjunctivitis, which may lead to ulcerative keratitis and perforation if not promptly treated Most cases occur in neonates and rarely occur in adults. The author experienced a case of gonococcal keratoconjunctivitis which was confirmed by conjunctival exudate smear, culture and biochemical study.

The laparoscopic cholecystectomy, performed for the first time in France in 1987, has been accepted as in many countries the method of choice when performing a cholecystectomy. The trend toward minimally invasive surgery has prompted general surgeons to try it instead of open cholecystectomy. We performed 1000 laparoscopic cholecystectomies at the Department of General Surgery of Eulji Medical College Hospital from January 1992 to April 1997. The outcome data have been analyzed retrospectively. Moreover, we have compared the case histories of 13 patients who received cholecystostomy with those of 43 patient who did not. We also present preliminary results for an interval laparoscopic cholecystectomy which was a preceded by percutaneous cholecystostomy. The results are as follows: 1) The mean age was 54.3 years ranging from 17 to 86; there were 402 males and 598 females. 2) Of the 1000 patients, 123 patients (12.3%) had a history of abdominal surgery. 3) More than half of the patients(560 patients, 56.0%) underwent operations within 6 months of the onset of symptoms. 4) A preoperative endoscopic retrograde cholecystoscopy was performed on 220 patients (22.0%), and of these, 93 patients received endoscopic sphincterotomies because of bile duct stones. 5) The majority of patients(744 patients, 74.4%) had laparoscopic cholecystectomies which lasted 40 minutes or less. 6) More than half (54%) of the removed gallbladders showed grade II inflammation. 7) Drains were used in 142 patients (14.2%). 8) Postoperative complications were encountered in 48 patients (4.8%). 9) Postoperative oral intake was resumed within 24 hours in most patients. 10) Most patients(854 patients, 85.4%) were discharged within 3 days of the operation. 11) The pathologic diagnosis was chronic nonspecific inflammation in most cases (823 cases, 82.3%). 12) The most common microorganism in the bile was E. coli. 13) Patients who received a cholecystostomy had many benefits: a shorter operation time, a low rate of open cholecystectomy, early oral intake. 14) For the 1160 patients who underwent a cholecystectomy during the same period, the rate of open cholecystectomy was 13.8%.

PURPOSE: To investigate the relationship of refraction, geometry of the posterior corneal surface and the residual corneal thickness after excimer laser photorefractive keratectomy. METHODS: Thirty eyes of 15 patients were treated with Star S2 Smooth Scan (VISX, U.S.A.) and followed up for 3 months. The refractive, anteroposterior changes in the posterior corneal surface and residual corneal thickness were measured using slit-scanning topography, Orbscan IIR (Orbtek, Bausch & Lomb) at 1 week preoperatively, and 1 and 3 months postoperatively. RESULTS: Mean forward shift of the posterior cornea surface was 8.83+/-1.34 micrometer, 11.53+/-4.23 micrometer and 14.70+/-3.50 micrometer at 1 week, 1 month, and 3 months respectively. Mean spherical equivalence of posterior cornea was = -7.01+/-0.31 D preoperatively; it changed to -7.17+/-0.47 D, -7.22+/-0.21 D and -7.17+/-0.6 D at 1 week, 1 month and 3 months. The degree of forward shift of posterior corneal surface is correlated with the posterior corneal refractive changes (r=-0.808, P< 0.01). The forward shift of the posterior corneal surface is correlated with the residual corneal thickness (r=-0.483, P< 0.01). CONCLUSIONS: Photorefractive keratectomy significantly influenced the forward shift of the cornea, which is correlated with the residual corneal thickness.

PURPOSE: To assess the the accuracy and variability in pachymetry measurements obtained by Orbscan and ultrasonic pachymeter in laser in situ keratomileusis (LASIK). METHODS: Thirty two eyes of 16 patients before LASIK were measured by ultrasonic pachymeter and Orbscan. Thirty eyes of 16 patients that had LASIK were measured by ultrasonic pachymeter and Orbscan postoperatively. The theoretical residual corneal thickness was compared to measurements by both instruments in eyes that had LASIK procedures. RESULTS: The ultrasound pachymeter measurements (543.8+/-24.2 micrometer) were thicker than the Orbscan pachymetry measurements, (541.2+/-24.9 micrometer) by mean of 2.7+/-7.4 micrometer (SD), preoperatively. But this is not statistically significant (p>0.05). Postoperatively, the ultrsound measurements were consistent with theoretical residual corneal thickness, 461.8+/-37.4 micrometer versus 467.9+/-30.71 micrometer (p=0.064), while Orbscan measurements were statistically less than the theoretical residual corneal thickness, 433.2+/-48.75 micrometer versus 464.32+/-33.4 micrometer (p<0.001). CONCLUSIONS: In LASIK eyes, the ultrasonic pachymetry was a more accurate measurement of corneal pachymetry than Orbscan topography system.

PURPOSE: The author compared the effect of the cup-to-disc ratio using the Volk Superfield lens and optical coherence tomography (OCT) to evaluate its usefulness in glaucoma diagnosis and follow-up. METHODS: One hundred ninety-seven eyes of 100 patients were enrolled: 34 normal, 75 glaucoma suspected, 43 normal tension glaucoma (NTG), 45 primary open angle glaucoma (POAG). Routine ophthalmic examinations, fundus examinations, and cup-to-disc ratio measurement using the Superfield lens after pupil dilatation, visual field test, OCT optic nerve head analysis, and OCT retinal nerve fiber layer analysis were performed. The author compared cup-to-disc ratio using the Superfield lens and OCT in normal, glaucoma suspected, normal tension glaucoma, and primary open angle glaucoma. RESULTS: Using the Superfield lens, the mean cup-to-disc ratio was 0.36+/-0.07 in normal eyes, 0.61+/-0.12 in suspected glaucoma, 0.75+/-0.11 in NTG, 0.70+/-0.17 in POAG. Using OCT, the mean cup-to-disc ratio was 0.58+/-0.13 in normal eyes, 0.69+/-0.12 in suspected glaucoma, 0.80+/-0.10 in NTG, and 0.76+/-0.15 in POAG. In all groups, cup-to-disc ratio using OCT were greater than using the Superfield lens and were statistically significant. CONCLUSIONS: Considering these differences in the clinical assessment of glaucoma, the combined use of the Superfield lens and OCT would be helpful in its diagnosis and follow-up.

A series of 135 cases of pterygium observed at the Eye Dept. in the National Medical Center from April 1963 to May 1966, were treated with thio-tepa after the surgical removal and were studied clinically in regard to the incidence of the recurrence. Among the total series, only one case showed no response to the thio-tepa instillation and the recurrence persisted. There was a case of allergic response to the thio-tepa, which has not been found in any reports known. No serious local or systemic toxcity or any sequelae such as corneal damages, defective vision or the interference with wound healing could be observed.

The increase of preoperative intraocular pressure by anesthetic is a troublesome problem in pin point anesthesia. In order to evaluate the efficacy of 4% lidocaine with less volume in pin point anesthesia 60 cataract surgeries were performed with different anesthetic dosage divided into 3 groups and compared preanesthetic with postanesthetic intraocular pressure and pain score(1; mild, 2; moderate, 3; severe). In the group 1(20 eyes), using 0.3ml of lidocaine, intraocular pressure change from preanesthesia to postanesthesia was 11.83+/-3.44mmHg to 12.19+/-3.27mmHg and there was no statistical significance(p=0.1025). In the group 2(20 eyes), using 0.4ml of lidocaine, intraocular pressure change was 11.53+/-3.22mmHg to 12.33+/-2.91mmHg and was statistically significant(p=0.0028). In the group 3(20 eyes), using 0.5ml of lidocaine, intraocular pressure change was 12.07+/-2.34mmHg to 13.41+/-2.51mmHg and was statistically significant(p=0.0000). Pain score in 3 groups were 1.60+/-0.17, 1.55+/-0.14, 1.35+/-0.11 and there was no statistical difference in 3 groups(p=0.5192). With these results, pin point anesthesia using 0.3ml of 4% lidocaine might be another useful local ocular anesthesia for the routine cataract operation.

To evaluate the consistency of the thickness and size of the corneal flap made by the Innovatome automatic microkeratome and to determine the cor-relation between preoperative variables and corneal flap dimensions, we per-formed the prospective study comprised 102 consecutive eyes of 51 patients having laser in-situ keratomileusis (LASIK)with the Innovatome microker-atome.Central corneal thickness, corneal curvature, and refractive error were measured preoperatively.All flaps were created using No.170 blades. The mean corneal flap thickness was 139.70 +/-2 2.5 6 micrometer, and the range was 93.0 ~193.7 micrometer.There was no relationship between the corneal flap thickness and the preoperative corneal curvature or spherical equivalent, but the corneal flap thickness increased with the preoperative central corneal thickness. The mean corneal flap size (vertical diameter)was 9.17 +/- 0.25 mm (range :8.5 0 ~9.7 5 mm).There was no relationship between the corneal flap diameter and the preoperative central corneal thickness or spherical equivalent, but the corneal flap size increased with the preoperative corneal curvature.

Visual acuity refers to the spatial limit of visual discrimination. It is surely the single most significant measure of functional integrity of the eye. Normal visual acuity can be represented in hyperopia of less than 2 diopters or astigmatism of less than 1 diopter. The purpose of this study was to observe the prevalence, type and degree of of refractive errors in 338 eyes of 40-69 years of age with normal visual acuity(20/20 or more). The results were as follows: 1. In objective manifest refraction, 246 eyes(72.8%) had refractive error such as hyperopia(110 eyes), simple hyperopic astgmatism(61 eyes),compound hyperopic astigmatism(57 eyes) and simple myopic astigmatism(18 eyes). 2. In subjective manifest refraction, 132 eyes(39.1%) had refractive error such as hyperopia(51 eyes), simple hyperopic astigmatism(44 eyes), simple myopic astigmatism(24 eyes) and compound hyperopic astigmatism(13 eyes). 3. As to the type of astigmatism, 71 of 81 astigmatism were "against the rule" and the rest(10 eyes) "with the rule". Degree of astigmatism was less than 1.00 diopter. 4. A verage degree of refractive errors was 0.43 diopter.
