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.

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.

Journal of the Korean Ophthalmological Society 1977;18(4):363-367
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.

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.

Journal of the Korean Ophthalmological Society 1980;21(4):381-385
The specimens taken from the corneal lesions of 298 corneal ulcer patients who vitsited our department from Jan. 1970 to Aug. 1980 were cultured on the Sabouraud glucose agar media and microscopic examination was performed with the slide preparation on wihch recultivated from the former media. The results were as follows: 1. Of the corneal ulcer patients, the cases caused by fungal infection were 77 (25.8 %) and its incidence was the highest in 1976 (17. 51.556) and the lowest in 1978 (7, 10.3%). 2. 14 species of fungus were observed: The common species, in order of frequency, were Aspergillus sp. (21, 27.2 %), Cephalosporium sp. (14, 18.2 %), Chloridium glaucum (8, 10.4%) and Candida albicans (7, 9.1%). Streptomyces sp., Monotospora sp., and Nocardia were the least ones (1 case respecively, 1.3%). 3. The sex ratio of the fungal corneal ulcer patients was 41 to 36 in male vs. female. The age distribution was from the age of 2 to 81 and the most patients were over age 40 (67, 87.0%). 4. The majority of fungal infections had onset during the warm seasons of the year: 49 cases occurred in the warm seasons (63.6%) and 28 the cold seasons (36.4%).

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.

7.A Case of Orbital Fibroma.
Journal of the Korean Ophthalmological Society 1973;14(1):27-29
A case of pure orbital fibroma was presented, which occured in the left eye of a 29-year-old Korean male. Decreased visual acuity and proptosis of 18 months duration were his chief complaints prior to his visit to hospital. Visual acuity was O.D. 1.2, O.S. 0.04, ocular movement of the left eye was limited to all directions and proptosis was toward the straight ahead. Affected eye ball was protruded 11 mm than that of the unaffected, and the left optic disk was pale. It was necessitated enucleation of the eye because the tumor was extensively grown in the apical portion of the orbit. Histology comfirmed the lesion to be pure soft fibroma.

8.A Case of Intermittent Exophthalmos.
Journal of the Korean Ophthalmological Society 1973;14(1):23-25
A case of intermittent exophthalmos observed in a 35 year old Korean woman is reported. For 3 years prior to her visit, she had experienced the occasional episode of exophthalmos, eyeache of left eye and headache, when she held her face bended downward for considerable period of time. Visual acuity of the patient was normal, and in her left eye there could be noticed 2mm of exophthalmos with the upright position and 7mm of exophthalmos with compression of the jugular vein, but no bruit or pulsation in the orbit was observed. Skull x-ray series were normal. Orbital venography was refused by her. It was decided that postural and behavior precaution was instructed for prevention of the exophthalmos and no further aggressive regimen was indicated in this case.

Journal of the Korean Ophthalmological Society 1998;39(2):400-405
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.

The human papillomavirus(HPV) has been implicated in the pathogenesis of human conjunctival papilloma, becauses it has clinically viral nature and pathologically koilocytosis, typically found in other papilloma-induced tumors. To evaluate the association of HPV with conjunctival papilloma, 3 recurrent conjunctival papiloma were removed through cryo-excision and examined for the presence of human papillomavirus by polymerase chain reaction. All 3 cases were positive reactions to papillomavirus serotype 6/11, but koilocytosis was present in 2 cases.
