RESUMEN
Each three rabbit corneas were stored in McCarey-Kaufman medium at 4 degrees C for 5, 9 and 14 days and used as donor materials in 6mm partial penetrating corneal allografts. These results were compared to that group of penetrating keratoplasties with corneas stored conventional moist chamber at 4 degrees C for 5 days. All the M-K media stored corneas for 5 and 9 days were in clear graft after keratoplasty during the observation period of 6 months but the corneas stored for 14 days were developed eventvally irreversilde opaque after grafts. At 6 months after keratoplasties allthe rabbits eyes were enucleated and sectioned for histopathologic study of endothelia with the light and electron microscopes. Endothelia of the corneas stored for 5 and 9 days showed rarely endothelial degenerative changes. But the corneas stored up to 14 days showed significant changes including of disappearanee of most endothelial membranes and cytoplasms in light microscopies and swelling of nucleus, dispersed chromatin clump, multiple small and large vacuoles in cytoplasm and occasional autolysis of cytoplasm were observed in electron microscopies.

Tuberous sclerosis is usually characterized by the triad of epilepsy, mental deficiency and adenoma sebaceum of the face. A 18-year-old girl was reported in which retinal phakoma, angiofibromas of the face and history of epilepsy occured with normal intelligence. On X-ray film multiple calcifications were, found in skull series. Also literatures were reviewed.

The authors ana lysed statistically seventy-five cases of the eye injuries in childhood under the age of 20 years old during a full year of 1972. 1. Incidence of eye injuries under 20 years old was about 1.1% of total out-patients and 39.9% of total eye injuries. 2. The most common objects to the injury were iron pieces or iron made materials (24%) such as needle, nail, flying iron piece, toy, wire and bar etc. 3. The most common nature of eye injuries was traumatic cataract (14.2%) 4. Seasonally the high peak of injuries was in summer (33.3%) and winter vacation (30.7%) 5. Blindness(under20/200 of corrected VA) was occured finally in 10.8% of total 75 cases.
