Traumatic optic neuropathy is one of true ophthalmic emergencies and there is no proven form of treatment for traumatic optic neuropathy. 82 cases of traumatic optic neuropathy were investigated to evaluate the effectiveness of high dose corticosteroid for the visual improvement. Age, sex, initial visual acuity, final visual acuity, interval to treatment, the type of trauma and the affected region were studied retrospectively.250 mg of Methylprednisolone was administered intravenously every 6 hours for 3 days, and then followed by tapering using oral prednisone The vision was improved in 36 of 82 cases[43.9%]. It was difficult to interpret the relation-ships between the affected region and visual improvement, the interval for each treatment and final visual acuity. However, the vision was improved in 45 of 50 cases who had an initial visual acuity of above light perception, but in the two of 32 cases with no light perception. If indicated, fifteen cases were treated with a combination of high dose corticosteroid and optic nerve decompression. In initial treatment of traumatic optic neuropathy, high dose corticosteroid was effecive. Whether or not initial visual acuity was better than light perception was a key risk factor in the outcome.

To study the effect of beta ray irradiation in preventing the recurrence of pterygium following surgical removal, clinical observation was made on 483 eyes in 447 patients who received. beta ray irradiation by 90Sr applicator (SIA-2) after operation for pterygium. Irradiation was given in doses of 360 rads 4 times with 2 days interval from immediately afteroperation. The results were as the followings: 1. Most cases were 31-40 years of age (158 eyes, 32.7% ); next, 41~50 years of age (112 eyes, 23.2%); the least, over 71 years of age (5 eyes, 1.0%). 2. All 483 cases consisted of 292 eyes (60.5%) in female and 191 eyes (39.5%) in male, but there was no significant difference in the site of the disease; right eyes, 257 eyes (53.2%) and left eyes (226 eyes)(46.8%). 3. Of all cases. 460 eyes (95.2%) was primary pterygium and 23 eyes (4.8%) recurrent pterygium. 4. Over all incidence of recurrence was 1.9% (9 eyes) of which primary pterygium occupied 1.7% (8 eyes) and recurrent type 0.2% (1 eye). 5. Of the patients with bilateral involvement, 3 cases showed unilateral recurrence.

Adenosine deaminase(ADA)has been used for the diagnosis of localized tuberculosis.The titer of ADA was measured from the ocular fluid of the patients who had undergone vitreoretinal surgery due to non-tuberculous vitreoretinal disease. Forty five patients were included and twenty patients were male. Mean age was 51.9 years. Four patients had diabetes mellitus and two had essential hypertension. The most frequent cause of vitreoretinal surgery was proliferative vitreoretinopathy(12 eyes). For the analysis of ADA titer, vitreous fluid(group I)was aspirated in 36 patients undergoing pars plana vitrectomy and subretinal fluid(group II)in 9 patients undergoing scleral encircling. Mean titer of ADA was 9.01+/-15.69 IU/L, and there was no significant difference on the statistics between group I(6.06+/-13.75 IU/L)and group II(20.83+/-18.17 IU/L). All 45 eyes showed negative reaction to polymerase chain againt tuberculosis, and 25 of 29 patients had positive reaction to tuberculin skin test. There was no statistically significant relationship between ADA titer and tuberculin skin test. This result suggests that ADA may be used for the diagnosis of posterior ocular tuberculosis, since the normal concentration in the posterior ocular fluid was compatible with the one in other body fluids where it has been used for the diagnosis of localized tuberculosis.

We studied clinical applicability of the contact transscleral retinopexy using the continuous-wave Nd:YAG (CW-YAG) laser. CW-YAG laser photocoagulation was done over sclera through contact probe in the pigmented rabbit eyes. Cryoretinopexy was also done and their morphologic findings were compared. Acute lesions produced with the laser photocoagulation were noted to have the characteristic white-colored distinct depigmentation. Its microscopic findings were oharacterized by choroidal necrosis, disruption of Bruch's membrane, dispersion of retinal pigment epithelial cells, and disorganization of sensory retina. Acute lesions after the cryoretinopexy were much more broader in its area and showed slight tanslucent retinal edema. Its microscopic findings showed relatively well-preserved choroid including Bruch's membrane. These data demonstrated that the contact transscleral CW-YAG laser retinopexy is capable of inducing more localized, stronger chorioretinal adhesion than the cryoretinopexy.

To evaluate factors related to success rate of dacryocystorhinostomy, we retrospectively surveyed 131 eyes about age, sex, symptom duration, etiology, obstruction site, sac size, silicone tube insertion and surgeons learning curve. Patients age, sex, obstruction site and sac size were not related to surgical results, but longer duration of epiphora, trauma, silicone intubation and poor surgical skill had relationship with poor surgical results. Surgical skill was the most important factor in multiple logistic regression. We believe that surgical technique for making a mucosal flap with bone removal etc., was very important to surgical success.

A classification and analysis according to sex, age, disease entity and operation was done on 772 inpatients (1008 eyes) admitted to the department of ophthalmology at Chonnam University Hospital. The results were as follows: 1) There were 477 males(61.6%) and 300 females (38.9%). Males far outnumbered females. 2) According to age, the largest group was under age 10,131 (17.0%), and the smallest group in their thirties. 68 (8.8%). 3) Surgical procedures were performed on 517 patients(67%) and not on 255(33%) 4) There were no significant differences in the distribution of the involved site; 272 (35.2%) were left eyes, 266 (34.5%) right eyes, and 234(30.3%) both eyes. 5) The most common ocular diseases were, in order of frequency, catarct(35.1%), trauma, glaucoma, and strabismus.

We performed clinical evaluations on 26 patients who were prescribed glasses with full correction and Fresnel prism for correction of abnormal head posture and/or diplopia due to incomitiant paralytic strabismus. There were 12 cases(46.2%) of superior oblique muscle palsy and 8 cases(30.8%) of lateral rectus palsy in order. Trauma was the most common cause, but non-traumatic cases were mostly caused by vascular disease of diabetes mellitus and/or hypertension. Abnormal head posture with diplopia and/or dissociated diplopia may be one of the causes of less satisfaction level than interval of prescription of Fresnel prism. Decreased visual acutiy happened when prescribed above ten prism prescription on one eye, and patients accepted with more ease when prescription wasdivided on both eyes, in spite of low prism power. We concluded that it is necessary to explain dimness due to decreased visual acuity when above ten prism power prescription is given on one eye even though prism was more effective method for diplopia gteatment.

Children with mature visual functions can suffer from diplopia when overcorrection after strabismus surgery occurred. If the patients are willing to undergo the adjustment procedure under a topical anesthesia, we feel that it is also possible to perform the strabismus surgery in the same manner. We operated 58 strabismic children (male 37, female 21) aging from 6 to 14 under topical anesthesia using only 0.5% proparacaine (Alcaine). After bow tie suture around end of the surgery, patients were assisted in sitting upright on the operating table, asked to fixate on a 20/40 accomodative target. Subsequently, we adjusted ocular alignment to nearly orthophoria. The overall success rate was 67.2% (39/58) ; horizontal strabismus with fusion potential (74.4%) was more successful than horizontal and/or vertical combined strabismus without fusion potential (52.6%) and one muscle surgery in horizontal strabismus regardless of fusion potential (36.4%). In conclusion, this study revealed that strabismus surgery under topical anesthesia had many advantages including day surgery, decreased complications and decreased the number of surgery.

Congenital esotopia is a constant esodeviation with a documented onset within the first six months of life, stably large angle and normal central nervous system. We examined 24 congenital esotropic patients with brain CT, electroencephalogram and the general developmental status. The rates of abnormal findings on brain CT were 8.3% and on electroencephalogram it were 33.3%. Four cases(l6.7%) of mild developmental delay and 2 cases(8.3%) of severe developmental delay were found pediatric consultation.
