The origin of the popliteal cyst is the popliteal bursa and frequently combined with the intraarticular lesion. And open excision has been commonly used as a treatment. The authors reviewed 39 cases of popliteal cyst in 38 patients, mangaged with arthroscopic method at Department of Orthopedic Surgery, College of Medicine, Korea University Hospital from June 1989 to July 1993 and the following results were obtained. l. Among 39 cases, 35 cases(89.7%) were associated with intraarticular lesions of the knee joint; 25 cases(71.4%) were chondral injuries, 6 cases(17.1%) were meniscus tear, 2 cases(5.7%) were rheumatoid arthritis and 2 cases were plica syndrome. 2. 20 cases(51.2%) were shown to have the communication between cyst and joint. 3. During operation, position change of the patient and another draping was not necessary. And the blue stained wall enabled authors to remove more completely the popliteal cyst than other conventional operative procedures. 4. Becuase of the short skin incision, the operation time was saved and we were able to recommend early excercise of the knee joint and ambulation. The operative treatment of popliteal cyst with the arthroscopy is the one staged method to excise the cyst and to intervent the combined intraarticular pathology which develop the cyst, and is one of the recommendable method bacause of small skin incision, short hospitalization and early rehabilitation.

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.

Fibrous histiocytomas are characterized by a variable combination of cells with fibroblastic and histiocytic features. They exhibit a distinctive but inconstant cellular arrangement referred to as a storiform or cartwheel pattern. Considerable corfusion has enveloped these tumors as a result of their various terminology-fibrous histiocytoma, dermatofibroma, sclerosing hemangioma, fibroxanthoma, subepidermal nodular fibrosis, xanthogranuloma, giant cell tumor of tendon sheath. A histologically benign but locally infiltrating, 15 * 20cm sized, fibrous histiocytoma was found in the posterior aspect of left thigh of a 17-year-old man. The tumor was incompletely excised due to adhesion of the tumor mass to sciatic nerve and then radiation therpy was combined, Histogenesis and prognostic aspects of the tumor are discussed.

Although vitiligo is a common disorder with well-known clinical features, its etiology is still vague. It has been suggested that immunologic factors are important in the pathophysiology of vitiligo. And the association of HLA antigens with vitiligo has been reported. Authors examined HLA phenotypes in thirty-nine patients, T lymphocytes in thirty- three patients, B lymphocytes in thirty-one patients, and quantitation of IgG, IgA, IgM and IEP(immunoelectrophoresis) in twenty-five patients with vitiligo in this study. T3 and T4 were investigated in twelve patients, CBC in thirty-nine and urinalysis in thirty-five patients with vitiligo for screening of associated diseases ; thyroid disease, anemia and diabetes mellitus. The results are as follows; The frequency of HLA A9, Bw15 and Bw22 was significantly decreased in vitiligo patients compared to control group(p=0. 003, 0. 02, 0. OR) 2. There were no significant differences in the results of total and active lymphocytes and B lymphocytes in vitiligo patients compared to the control group. The results of quantitation of IgG, IgA, IgM and IEP showed within normal lirnits except one, an increased IgG, 2,200rng/100ml (normal: 500 1,500) and polyclonal gammopathy. 4. Among twelve vitiligo patients, one showed increased TR, 355ng/100ml (normal: 80 220) and T4, 17. 3pg/100ml (normal: 5 13). 5. CBC and urinalysis were within normal limits in all patients.

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.
