The authors present a case of central retinal artery occlusion successfully treated by surgery combined with medical treatment. The patient was a 53-year-old Korean female who had central retinal artery occlusion with 3 hours duration. Her vision was F.C. 20 cm on admission and improved to I.O by paracentesis followed by medical treatment for 9 days.

Treatment of persistent uveitis with Methotrexate (MTX) in a 35 years-old Korean male has been reported. The patient vision was HM in right eye and 0.02 in left eye on admission, and improved to 0.2 in right eye and 1.0 in left eye after MTX treatment for 45 days. A brief review of literatures has also been described.

The early ultrastructural changes of basement membrane thickening and degeneration of the pericyte were noted in retinal capillaries in diabetic patients. However no early ultrastructural changes were reported in diabetic iris capillary. The authors studied the ultrastructural features of basement membrane of iris capillaries which were obtained during cataract surgery in five diabetic patients and compared with those obtained in five nondiabetic patients. The endothelium basal lamina, pericyte basal lamina and membrane-like pericyte matrix in didabetic iris capillaries were thicker than those in nondiabetic Iris capillaries. The thickening of pericyte basal lamina is more prominant than the endothelium basal lamina in diabetes. The duration of diabetes had no relationship to endothelium basal lamina but, showed statistically significant relationship to thickness of pericyte bascal lamina and pericyte matrix.

Pneumatic retinopexy is a new procedure that is effective in treating the uncomplicated cases of rhegmatogenous retinal detachments. The procedure of pneumatic retinopexy is composed of cryotherapy(photocoagulation), intraocular gas injection and postoperative positioning. The advantages of this procedure are less tissue damage, no hospitalization, reduced expense and minimal complication. For these reasons, this procedure has become popular retinal detachment surgeons. Peports of associated complications are still limited. The authors experienced one case of choroidal detachment after intraocular gas(SF6 gas) injection in rhegmatogenous retinal detachment in pseudophakic eye.

Tangential vitreoretinal traction around fovea is known to be the principal cause in the pathogenesis of idiopathic macular holes. According to the recent study, the internal limiting membrane(ILM) may provide a scaffold for fibroblast proliferation and contraction, therefore play an important role in the enlargement of macular hole. We removed the ILM during macular hole surgery and assessed the anatomical and functional outcome of the macular hole surgery. Twelve consecutive patients with full-thickness macular hole were enrolled in this study. They were examed for best-corrected vision, fundus photography, fluorescein angiography, Humphrey automated perimetry, focal eletroretinogram, before and after surgery. After surgery, vision was improved in 8 eyes(67%), hole was closed in 10 eyes(83%). Macular thresholds on visual field was increased in 8 eyes and peripheral scotomas developed in 3 eyes postoperatively. The amplitude increased in 7 eyes and the implicit time decreased in 8 eyes on focal electroretinograms postoperatively. Out results suggested that the complete removal of ILM should be attempted to improve vision and to close holes during the full-thickness macular hole surgery.

A case of tonic pupil in a 32 years-old Korean male has been reported. This is a rare disease and hitherto it is not reported in Korea. A brief review of literatures has also been described.

We present a case of sarcoidosis, which was associated with anterior granulomatous uveitis in both eyes and involvement of the right lacrimal gland in a 46-year-old korean female. The patient has nodules (various in size) on the nose, on the dorsum of right hand and on the back. Serum gamma globulin was elevated and in the nodules infiltration of giant cells, lymphocytes and epithelioid cells was presented, but no caseous necrosis.

Proliferative vitreoretinopathy is an abnormality in which the rhegmatogenous retinal detachment is complicated by proliferation of membrane on both surfaces of the detached retina and on the posterior surface of the detached vitreous gel. The contraction of these membranes, causing distortion and further elevation of the retina, is the most important cause of failure in retinal reattachment surgery. The author studied the ultrastructural features of preretinal and subretinal membranes which were removed during vitreous surgery in four patients with proliferative vitreoretinopathy. The results were as follows: 1. In the four preretinal membranes, five morphologically distinguishable cell types-retinal pigment epithelial cells, fibrous astrocytes, macrophages, fibrocytes and myofibroblasts-were observed, and the extracellular matrix was composed of collagen fibrils measuring 15-25nm in diameter. 2. In one subretinal membrane, retinal pigment epithelial cells, fibrous astrocytes and macrophages were observed and the major cell type was the retinal pigment epithelial cell. The diameter of the extracellular collagen fibrils was almost the same as that of the preretinal membranes. 3. In the preretinal and subretinal membranes, some of the fibrocytes and macrophages were believed to be derived from retinal pigment epithelial cells.
