Authore examined for the width, the trabecular pigment band and the iris process of the chamber angle in the non-glaucomatous eyes of the Korean people (total 86 eyes, among (them male 58 eyes, female 28 eyes, and ages of 7-67) by using the 3 mirror contact lens and slit-lamp (Goldmann 900). And these findings were evaluated with the age and the sex distribution. Also these preliminary data are now assisting in the study of pathologic findings of the chamber angle.

Authors experienced five different cases of keratitis such as metaherpetic keratitis, bullous keratitis, chemical keratitis and superficial punctate keratitis have been markedly improved by subconjunctival injection of Tathion (30-50mg), a glutathion prepartion. All cases showed remarkable improvement with better visual acuity following the treatment. Especially it was another choice of treatment in persisting case of metaherpetic keratitis with parenchymal infiltration. No side effects have been observed during this procedure.

The objects of the refractive examination are to check the refractive state of the eyes and to correct the refractive errors with glasses. This paper is directed to the basic methods of subjective and objective refractive examination.

Ketalar, a new parenteral anesthetic, was used as a clinical trial for 14 surgical cases ranged from 2 to 15 year old children, and also intraocular pressures of their patient's sound eyes were measured before and after Ketalar injection, I.M. 5-10 mg/kg. Unlike conventional anesthetic agents, Ketalar caused a significant rise in intraocular pressure within 5 minutes and then the pressure improved to normal range about 15 minutes after Ketalar injection. Ketalar could not recommended as a general anethetic agent in case who should examine the intraocular pressure. In eye surgery under 15 year old children, this agent would be a safe and effective general anesthetic, and in an emergent eye injured case, Ketalar is an agent of first choice and can injects to patient regardless of diet intake.

In search of the effect of air pollution on the eye, the authors examined ocular symptoms and diseases in both an urban(Seoul) and two rural populations (Suwon and Changsung). The Prevalence rate of ocular symptoms and diseases between 109 occupational drivers of more than 3 years career in Seoul area which is one of the air polluted urban areas and 150 populations in the two different rural areas as a control group were compared. The prevalence rate of ocular symptoms was 89% in Seoul, 10% in Suwon and 23% in Changsung area, and those of ocular diseases were 35%, 6% and 10% in the same areas, respectively. The prevalence rate of ocular symptoms and diseases is respectively 3 to 4 times more prevalent in occupational drivers than in the control groups. Many other etiologic factors such as occupation, labor condition, environmental stress or different way of living may influence the prevalence rate between the two groups, however, it would be presumed that the main causative factor to cause ocular symptoms and diseases is probably due to air pollution.

The authors analysed statistically 223 cases of the eye injuries among 17,547 out-patients who visited to our clinic located at down-town of the city during Jan. 1965 to Sept. 1967. The incidence of the eye injuries is remarkably lower than the other reports from other communities. As far as the objects of eye injuries were concerned, ironpiece, fist and coal-dust were more frequent in 21~40 year-age group, while in under 10 year age group, knife, nail and finger-tip were more frequent. Male was exceedingly prevalent (162) than female (61). 21~30 year age group was also prevalent in regard to the incidence of the injuries.

The author had a clinical experience with B. and L. Soflens in a total of 18 patients(28 eyes) from Sept. 1973 to March 1974. Among the patients, 14 used Soflens for an optical purpose (myopia and aphakia) and 4 patients for a therapeutical purpose. Most of these cases had worn hard contact lenses without success, as severe foreign body sensation, lacrimation and eye pain developed. With Soflens the foreign body sensation proved to be so mild, that most of the patients were able to wear Soflens for 14 hours per day. Also most of these cases wearing Soflens got the same good vision as with hard contact lenses All of the patients who were Soflens for the therapeutical purpose, that is the patients with Stevens-Johnson syndrome, exposure keratitis or essential corneal edema, showed good results. Other advantages of Soflens are: it is less movable on the cornea than hard contact lenses,it also does not come off easily. It gives stable vision for tho drawn-up pupil after cataract surgery. Within 6 months of observation Soflens caused no damage to the cornea or other complications except in one case, where a temporary peripheral corneal erosion was noted.

In order to evaluate the clinical application of the Nd:YAG laser(Coherent model 9900(R)) to correct the astigmatism, we observed the change in corneal curvature, thickness and endothelium after laser radiation to the rabbit cornea. The experiment composed of 14 rabbit eyes divided into two groups according to the power setting; 7 eyes of 2.5mJ group, and 7 eyes of 5mJ group. Lader pulse was focused at corneal epithelium and an average of 25-30 applications were required to make the single pair of transverse line like conventional lineal corneal transverse incision for one eye. Changes ir keratometry and pachymetry were measured postlaser application for 3 months. Seven days after radiation, two rabbit eyes(2.5mJ and 5mJ) were enucleated for scanning electron microscopy. The results were as follows: 1. The mean flattening induced at 900 meridian was 1.91 diopter in 2.5mJ group and 1.98 diopter in 5mJ group 3 months after laser radiation, and the difference between the two groups was not statistically significant(p>0.5). 2. The steepening at 1800 meridian induced only one week after laser radiation in both groups, thereafter the flattening was shown. 3. The significant mean corneal thickness increase of 30.72pm in 2.5mJ group and 33.47 micrometer in 5mJ group was noted at postlaser 7 days and returned to normal range at postlaser 2 months, but the corneal thickness showed no significant statistical difference between two group(p>0.5). 4. Scanning electron microscopy findings showed changes of the ultrastructure of the endothelial cell: edematous changes of the endothelial cell and cell membrane destruction were much less in 2.5mJ group than 5mJ group.
