The athors have presented recently treated 4 cases of malignant tumors of the eye and adnexa. 1. All of them were rapidly aggrevated after previous incompleted surgical management (3 cases) or postponement 01 operation (1 case). 2. Three cases of them except adenoid cystic Ca. were recurred after orbital exenteration. 3. The authors were concluded that the poor prognosis is due to its nature of malignancy and delayed radical surgical management.

We presented several cases of the exophthalmos due to the orbital tumors, with the review of the literatures. We performed modified Kronlein operation and anterior orbitotomy, appropriately for each cases to improve the visual acuity and at least to correct cosmetically the proptosed eye. It will be better to do one's best in order to search a possible way to save the eye ball by which the ophthalmologist can remove the orbital tumor even if the patient lost his vision.

Authors observed two cases in which the formation of glass-like hyaline membranes in the anterior chamber caused by birth trauma. Case 1 revealed a curtain-like glass membrane in the anterior chamber with a central nubecula corneae of right eye (Fig. 1). Case 2 revealed two paralled glass membranes and its stripes extended across the anterior chamber attached at each extremity to the posterior surface of the cornea (Fig. 2).

The purpose of this paper is to study the effects of anti-inflammatory agents on the blood-aqueous-berrier in experimentally induced uveitis. 10% solution of sodium fluorescein was injection intravenously in the ear vein of rabbits (0.25 ml/kg) and fluorescein curve was drawn after the method of Amsler and Huber. Experimental uveitis was induced by the injection of 0.2 ml of human serwn into the vitreous body. After uveitis had been induced. three kinds of anti-inflammatory agents-Prednisolone, Benzyron and Methotrexate-were Biven oralIy. In control animals in which no uveitis was induced, no changes in fluorescein curve were demonstrated before and after the administrations of drugs. In animals with uveitis, maked increases of the blood-aqueous barrier were noted. When Benoyron and Prednisolone were given to these animals, normaliration of the fluorescein curves were demonstrated. Methotrexate had no effects on the fluorescein curves in uveitis animals, showing no improvements in the permeability of uveal vessela. This ineffectiveness seemed to be due to the resistance of rabbits to methotrexate.

Authors performed 25 corneal grafts in 24 patients since the inauguration of The Central Eye Bank, attached to the Department of Ophthalmology, St. Mary's Hospital, Catholic Medical College, in April 19, 1967. Method and results of these cases are as follows; METHOD: In technique of surgery, the grafts in most of the cases were 7 mm in diameter(Table 3), in two types of penetrating and lamellar corneal grafts(Table 4). The donor material came from patient age group of 51-60 years old in most and was used within 24 hours after death (Table 5). In most cases we placed 12 interrupted sutures except of two cases for continuous suture by 8-0 virgin silks. Preoperative and postoperative cares were routine with systemic dexamethasone, 7.0mg a day was given routinely on the 5 th postoperative day for 30-50 days because of prevention of graft rejection. RESULTS AND SUMMARY: Table 7 summbrizes the results of our observation. Nineteen of the 25 grafts remained clear. And there was improved vision above 20/200 in ten eyes out of nineteen clear grafts. Table 10 lists the reasons why nine clear grafts did not improve vision. Postoperative complications occurred in fourteen grafts (Table 11). Penetrating corneal grafts for adherent leucoma courneae, staphyloma corneae and corneal scars from alkaline burn were failed to maintaining the clear graft. The donor material, the recipient cornea, graft rejection as a complication and its prevantion were discussed.

Recently cryogenic therapy is widely used for the treatment of herpes simplex keratitis. We had experimental studies on the effect of iodine cautery and cryocautery upon the regeneration of corneal ulceration. On 10 adult albino rabbits, one eye was treated by iodine, and the other by cryocautery in area of 0.6cm X 0.6cm. The epithelium in this area was completly removed by cotton applicator. There after, the rate of epithelial regeneration was observed every 12 hours. The results were as follows: (1) The average period of complete epithelial regeneration was 48 hours in animal treated with cryocautery and 78 hours in animals treated with iodine cautery. This difference is statistically highly significant. (2) Corneal opacity was not demonstrated in eyes treated with cryocautery. Six eyes treated with iodine, however, showed various degree of corneal opacities. These results support the view that the healing time in human herpes simplex keratitis is shortened in patients with cryocautery as compared with iodine.

PURPOSE: To investigate whether there is a difference in ON- and OFF-responses of the photopic electroretinogram (ERG) in glaucomatous eyes. METHODS: Photopic ERG and optical coherence tomography were performed in 15 normal, 13 glaucoma suspect, and 22 glaucoma subjects. Amplitudes and implicit times for a, b, d, i, photopic negative response (PhNR), and retinal nerve fiber layer thickness were compared among the three groups. RESULTS: The PhNROFF amplitude (microV) was 19.05 +/- 11.41 in the glaucoma group, 14.24 +/- 10.37 in the glaucoma suspect group, and 2.69 +/- 12.16 in the normal group, demonstrating a significant difference among the three groups (p < 0.01). The PhNRON amplitude (microV) was 20.15 +/- 13.99 in the glaucoma group, 31.49 +/- 17.09 in the glaucoma suspect group, and 37.59 +/- 9.53 in the normal group, a significant difference (p < 0.01). However, there was no significant difference between the three groups. The ON-OFF response PhNR amplitude was correlated with retinal nerve fiber thickness (r = 0.481, r = -0.480, respectively), and areas under the receiver operating characteristic curve were 0.782, and 0.718, respectively. CONCLUSIONS: There is a potential role for the ON-OFF response PhNR in early detection of glaucomatous damage.

PURPOSE: To evaluate spectral-domain optical coherence tomography (SD-OCT) images of acute central retinal artery occlusion (CRAO). METHODS: Six eyes of 6 patients who were diagnosed with acute CRAO were enrolled in the present study. The main SD-OCT measurements included macular thickness in the macular cube map and retinal thickness in the 5-line raster map. RESULTS: In acute CRAO, macular thickness increased more than that in the normal fellow eye in all cases. SD-OCT images demonstrated increased reflectivity and thickness in the inner retinal layer, especially in the nerve fiber layer and ganglion cell layer. However, in the outer retinal layer, SD-OCT images disclosed decreased reflectivity and increased thickness. The central subfield thickness area image showed normal reflectivity and thickness. The horizontal cross-sectional image showed relatively the same edema ratio between the inner retinal layer and outer retinal layer thickness. There was no cystoid or serous foveal detachment-type edema. CONCLUSIONS: SD-OCT images of CRAO showed increased outer retinal layer thickness and decreased reflectance as well as increased inner retinal layer thickness and reflectance. However, inner segment and outer segment junctions of the photoreceptor and retinal pigment epithelial signal were intact.

PURPOSE: To evaluate the changes in corneal higher-order aberrations (HOAs) after penetrating keratoplasty (PKP) and to investigate the factors affecting the changes in corneal HOAs. METHODS: Forty-eight eyes of 48 patients with three different underlying diseases who underwent PKP were retrospectively reviewed. The changes in corneal higher-order aberrations (total root mean square (RMS), coma, trefoil, and spherical aberration) were evaluated with Pentacam (Oculus Inc., Dutenhofen, Germany) at 1, 3, 6, 12, and 18 months postoperatively. Sex, age, underlying disease, suturing method, trephine size of donor, and suture state were analyzed as factors affecting the HOAs changes. RESULTS: Total RMS values in the PKP eyes were 1.67 +/- 0.49 microm at 1 month, 1.63 +/- 0.49 microm at 3 months, 1.64 +/- 0.51 microm at 6 months, 1.61 +/- 0.50 microm at 12 months, and 1.79 +/- 0.40 microm at 18 months after surgery (p < 0.01). The values were higher compared with those in the control eyes. Sex, donor trephine size and suture method did not correlate with the HOAs changes. The HOAs in the keratoconus group were higher than those in the corneal opacity group or bullous keratopathy group. At 18 months, HOAs in the suture removed group were higher than those in the suture-remaining group. CONCLUSIONS: Corneal HOAs after PKP were persistently higher than those in the control eyes. The HOAs were higher in patients with keratoconus and in the suture-removed group.
