Congenital cryptophthalmos is very rare, according with Duke-Elder's System of Ophthalmology(Volume 3, Part 2) some 50 cases having been recorded since Zehender and Manz's(1872) original observation. I observed the congenital ocular deiermities in siblings; out of 10 siblings, 2 were affected. A 15-year old girl had cryptophthalmos unilaterally with other gross anomalies of the face. One of her brother (27-year old) had congenital microblepharon, coloboma of eyelids, microphthalmos and symblepharon bilaterally. The surgical amelioration of cryptophthalmos was attempted but it was impossible.

Follow-up examination was done in 28 eyes of 28 leprosy patients in So-Rok Do national leprosarium that were operated on for complicated cataract six months ago. Their visions were then hand movement or light perception. Six months later results were as follow; (1) 15 eyes have more than 0.1 of corrected vision (Table 1). (2) 9 eyes have corrected vision from finger counting to 0.05 (Table 2). (3) 1 eye has vision of hand movement and 3 eyes were blind. (Table 3).

Between Oct. 1965 and Oct. 1970 467 eyes (450 patients) which recieved Sr90 (beta-ray) irradiation postoperatively were observed clinically at Severance hospital. 1) Among 467 eyes (450 patients), 321 eyes (68.7%) were referred to this hospital for postoperative beta-ray irradiation only (Fig.1). 2) 4500 rep of Sr90 were given to each eye in three equally divided doses. One 1st does was given about 24hours after surgery and the other two doses were given at one week inteintervals. 3) There was no significant sex difference in the number of patients-male (215 patients) and female (235 patient). 4) The oldest patient was 82 years and the yougest 16. 5) The greatest number of patients were between 31 and 40 year old (34.2%) and only one was over 81 year old (0.2%). 6) 230 left eyes were involved and 203 right eyes 17 patients had pterygium bilaterally (34 eyes). 7) 42 eyes had recurrent pterygium, there was no sex relationship in number of recurrences and no difference between right and left eyes developing recurrent pterigia. 8) Among 467 eyes which received post operatives sr90 irradiation, the incidence of recurrence was 2.8% (9 eyes).

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.
