Postoperative Sr90 Irradiation of Pterygium

Between Jan. 1971 and Dec. 1974, 324 eyes which received Sr90 irradiation postoperatively at Severance Hospital and 819 eyes which received Sr90 irradiation postoperatively at a private eye clinic were observed. Among 324 eyes which received postoperatives Sr90 irradiation at Severance Hospital and 819 eyes which received postoperatives Sr90 irradiation at a private eye clinic, the incidences of recurrence were 3.4% and 3.3%.

Clinical Studies on Cataract Surgery Patients

Surgery of the lens of the eye is almost exclusively limited to that which is done for a cataract. It is this type of operation which has it possible for the greatest number of the blind to recover vision. There is documentary historical evidence that surgery for cataracts was performed by the ancient Egyptians, Greeks and Romans. The first recorded extraction of the opapue lens was done by Davial in 1745 who used a triangular knife to section the limbus. Subsecuently the fact that many eyes lost their sight because of infection prevented the widespread use of this impor tant surgical discovery until the Listerian epoch. Since 1870 and the advent of antisepsis the use of this operation for cataracts has become generalized so that today its use is widespread. Also there has been development and progress in the method of surgery. Although there are many serious complication which may follow the extraction of a lens for cataract, the incidence of such is relatively rare. This study is based on a survey of the results of 479 cataract operations each performed under similar conditions, but using a variety of operative techniques. These operations were performed at Y.U.M.C. Department of Ophthalmology between 1964 and 1973. The results of the study are summarized as follows: 1. From 1964 through 1973 there were 384 cataracts done on 225 males and 159 females. 2. Cataract extration were done upon 479 eyes. The types of cataracts are: senile 341, traumatic 57, complicated 35, congenital 21, other 25. 3. The incidence of operative complications was: vitreous loss 17.2%, capsul rupture 6.5%, iris prolapse 1.7%. 4. Early postoperative complications included: striate keratitis 55.2%, hyphema 22.9%, infection 3.1%, pupil drown up 1.5%, iris prolapse 1.5%, conjunctival bleb 1.3%. 5. The following were late postoperative complications: corneal edema 2.4%, glaucoma 2.1%, retinal detachment 2.0%, uveitis 1.1%.

Refraction in School Children

518 children (282 boys and 236 girs) of a primary school were determined under mydrin-p instillation. (1) Among 518 children, Ammetropia was 43.6% emmetropia 56.4%. (2) As to the distribution of refractive error 38.2% were hyperopia and 4.1% myopic. (3) There was an anuual decrease in the incidence of hyperopia both in the country and city. In contrast, the incidence of myopia showed an annual increase in city only. (4) The majority of refractive error were less than 3 diopter. (5) "With the rule" astigmatism was more commonly found than "against the rule". (6) The incidence of myopia among primary school children in the country had dropped to 4.1 % as compared with 13.7% in city.

Refraction in School Children

645 children (330 boys and 315 girls) of a primary school were determined under 2% Cyclogyl. (1) Among 645 children, refractive error was 57.2% and emmetropia 42.8%. (2) As to the distribution of refractive errors, 33.8% were hyperopic and 11.4% myopic. Hyperopia was more common than myopia. (3) Hyperopic refractive error was increased until 7 years of age. Since then it has been decreased yearly. Myopic refractive error has been increased yearly since 8 years of age. (4) The refractive errors were relatively equall rate in girls(28%) and boys(29%). (5) Refractive errors were numerous around the age of 7(24.7%). (6) The degree of refractive errors varied, but in the great majority was less than 3 diopters. (7) As to the type of astigmatism, 75% were with the rule and 23.7 were againat the rule. (8) The myopic refractive errors were decreased in 1973 year(24.7%) than 1957 year(27.5%).

A Case of Malignant Melanoma in the Conjunctiva

A case of malignant melanoma occurres in the palpebral conjunctiva is presented. A 30 year old woman had dark brownish, strawberry-like pedunclated mass in her lower conjunctiva which was removed and confirmed as malignant melanoma by histopathology.

The Congenital Coloboma of the Choroid

We report of 3 cases of atypical coloboma of choroid. The two of these were one male and one female. A man aged 40 discovered atypical coloboma of choroid bilaterally with red-green color blindness. One of his son aged 6 discovered atypical coloboma of choroid bilaterally with nystagmus. One of his daughter aged 11 discovered of atypical coloboma of choroid bllaterally with alternating exotropia.

A Statistical Observation of the Ocular Injuries (II)

The authors analysed statistically 4,231 Cases of the ocular injuries among 19,204 Out-and Inpatients who visited to the local eye clinic at Young-Deong Po, where are many factories, from Jan. 1971 to Dec. 1971. The incidence of ocular injuries was increased about two times as much as that in 1964 at this eye clinic and was more prevalent than other places. It was shown that the incidence was exceedingly more prevalent in male than in female and iron piece was most freguent one among materials which caused trauma(64.7%). Most of the patients were improved well with proper early management of trauma. 6.6% resulted in blindness.

A Statistical Observation of Blind Eyes in O.P.D. Patient

The 976 blind eyes among the 40986 out patients who visited to Dept. of Ophthalmology, Severance Hospital, Yonsei University Medical College from Sep. 1965 to Feb. 1972 were statistically evaluated. Blindness included visual acuity of F.C./lm. or less. The 817 blinds were ranged from infants to very eldety persons. For the evaluation of the site of blind eye, 159 persons(19.5%) were binocular and 658 persons (80.5%) monocular 331 persons (40.5%) were blind in the right and 327 persons (40%) in the left. In terms of frequency, the principal causes were lesions affecting the lens. 31.2%: the glsbe, 25. 3%: the cormea, 16.8%: the retina, 10.8% the optic nerve, 5.9%: In the blind eyes were due to trauma and 12% due to infectious and systemic disease. The blind eye disease was the cataract. 27.5%: the phthisis butbi. 14.1%: the cormeal opacity and ulcer. 12.8%: the glaucoma. 5.5%: the optic nerve atropy. 4.7%: the anophthalmos. 4.0%: the retinal detachment, 3.4%.

A Statistical Observation of the Corneal Foreign Bodies

The authors have statistically analysed 359 cases of corneal foreign bodies among 636 cases of ocular injuries in 5.420 Out-and In-patients who visited to a private eye clinic at Young Deong-Po (from Jan 1. 1964. to Dec 31. 1964). 1. The incidence of ocular injuries was 11.7% of all eye patients. 2. Ocular foreign bodies occupied 66% of ocular injuries. Extra-ocular foreign bodies (97%) was much more than intra-ocular (3%). 3. Incidence of Corneal foreign bodies was 88.4% of extra-ocular foreign bodies, which was 56.6% of ocular injuries in this clinic. 4. They (corneal foreign bodies)were mostly male (91.2%) and ranged from 11 to 40 year old. 5. The most common cause of corneal foreign body was iron piece. 6. The prognosis for vision was almostly good when early removal of foreign bodies and proper post operative cares were performed.

A Statistical Observation of the Ocular Injuries (I)

The authors analysed statistically 314 cases of the ocular injuries among 37.826 Out and In-patients who visited to Severance Hospital for 6 years duration (from sept. 1965 to Aug. 1971). Male (72%) was three times as much as female (28%) among the patients and they were mostly 2nd and 3rd decades. Most frequent causes of injuries were finger. fist and iron pieces which mainly resulted in subconjunctival hemorrhage and corneal foreign body.

Refraction in High School Students (I)

This study was planned to determine the subjective and objective refraction under Mydrin P (Sansei Do Pham. Co.) among 758 Korean high school girls in Seoul area age of 12 to 18 years. Brightness (illumination) of 6 class rooms out of 30 in junior high school and 11 class rooms out of 24 in senior high school was measured with a sight meter (Western model 703-60, type 7, Western Co.) and a sun light illumination meter (Western model 756, Weston Co.). 1. Among 758 high school girls, error was 80.34% and emmetropia 19.66%. 2. As to the distribution of refractive erros, 30.02% was hyperopic refractive error and 69.98% was myopic refractive error. 3. The incidence of each refractive errors was the following order: hyperopia 15.44%, myop4 37.40%, compound myopic astigmatism 15.04%, compound hyperopic astigmatism 5.54%, simple myopic astigmatism 3.23%, simple hyperopic astigmatism 2.9%, mixed astigmations 0.73%. 5. The incidence of refractive errors in relation to age reveals the myopic refractive error increases from 37.35% at the age of 12 years reaching to 97.06% at the age of 18 years, while the hyperopic refractive error decreases from 62.65% at the age of 12 years decreasing to 2.94% at the age of 18 years. 6. Emmetropia was most frequent at the age of 16 years and there after tends to decrease. 7. Hyperopic refractive error under 1.00D was 23.99% and myopic refractive error under 1.00D was 26.62%. 8. As to the type of astigmatism, "with the rule" was 52.88%, "against rule" 40.14%, "oblique" 4.33% and mixed astigmatism 2.64% only. 9. The brightness of classrooms reveals averaing 75.5 F.C. in senior high school and 30.2 F.C. in senior high school. The day light factor measured at the same time was average 6.2% in junior high school and 1.8% in senior high school. The balance of illumination measured at the sametime was average 69.8% in junior high school and 52.6% in senior high school.
