RESUMEN
Fluorescein fundus angiography is a valuable method in diagnosis and treatment of central serous chorioretinopathy. We observed 136 eyes of central serous corioretinopathy by fluorescein fundus angiography, between March, 1973 and September, 1974. Leakings are analysed by pictures and the following results were obtained. 1. The cases were classified by leaking patterns as following: Type I, leaking is unremarkable, Type II, leaking point appears at early arterial phase and fades out gradually. Type III. leaking point appears at early arterial phase and increases in density gradually, but the size of the leaking area is not enlarged. Type IVa, leaking point appears at early arterial phase and increases concentrically in the density and size. Type IVb. leaking point appears at early arterial phase and increases vertically (mushroom shape) in its size and density. 2. In large serous detachment of the macula, the leaking tend to be single and located at peripheral area. 3. In type IVa and IVb, the leaking tend to be located superiorly and nasally in midperiphery. 4. Photocoagulation can be applied more easily in type IVa and IVb for the location of the leaking points.

Positive contrast orbitography was performed on 5 cases with hypaque under the fluoroscopy using the General Electric television angio-unit. Tumors were outlined in all cases and their size and extent were verified by operation in four of them. All of patients complained of retro-ocular tension and edema of their conjunctiva and eyelids, but about 3 hours later, there were no remained symptoms except hyperemia of their conjunctiva.

1. A comparative studies of the effects of Varidase and Urokinase on the experimental hyphema produced by the injection of rabbits auto-blood were performed in 20 eyes. 2. Subconjunctival injection of each enzymes were perfomed 1 hour after production of hyphema, and thereafter repeated once daily for 10 days. 3. Varidase increased the rate of absorption of hyphema, but Urokinase had no effect. 4. No side reactions were observed following the subconjunctival injection of these enzymes.

Authors presented the statistical analysis for 81 patients of Retinal Detachment observed at Department of Ophthalmology, Seoul National University Hospital, for the last 3 years. 1) Male had the preponderance over the female in frequency and the peak was at 20~40 age group. 2) Patient's chief complaint was mainly the decreased visual acuity, and only 33% of patients was seen within 2 weeks after onset, and 75.6% had the visual acuity under 0.2. 3) The intraocular pressure of affected eyes was hypotensive in 63.7% of the cases. 4) The extent of detachment was limited to the one half of the retin a in 62% of the eyes. 5) The site of retinal breaks was mostly at the temporal half of the retina and located from ora to equator, and horseshoe shaped tear was more prevalent. 6) The traumatic cases were more frequent in the etiology of retinal detachment. 7) The better result was obtained after retinal reattachment operation in the following groups. a. 21~40 age group. b. within 2 weeks of duration. c. visual acuity over 0.2. d. extent of detachment less than one halt of the retina. e. dialysis or hole in retinal breaks. f. retinal break between ora and equator. g. cases that the retinal breaks were found. h. primary operation. 8) The visual acuity was significantly improved in cases of successful reattachment and vitreous opacity was the most frequent post operative complication.
