Marfan Syndrome is a rare congenital disease characterized by the abnormalities of Sheletal system, eye and cardio-vascular system which was initially desiribed by Marfan in 1896. One case of marfan syndrome was treated at the department of Orthopedic Surgery, College of Medicine, Seoul National University for multiple skeletal deformities. Moderate degree of scoliosis was treated with Milwaukee brace and finger deformities with Z-plasty and full thickness skin graft.

Two hundreds cases of spine tuberculosis were treated surgically for the period of 7 years between 1970 and 1976 at Seoul National University Hospital and following results were obtained. 1. Many patients failed to be treated with conservative method. Spontaneous fusion was found in 10% of 200 cases with long duration of disease. Anterior fusion was performed in 166 cases and posterior fusion was carried out in 34 cases. In those 34 cases, anterior currettage was combined in 7 cases, anterior fusion combined in 19 cases in which 7 cases were performed anterior and posterior fusion at one stage. Posterior fusion alone was carried out only in 8 cases. 2. Anterior fusion is indicated for: a. decompression in cord involvement b. confirmation of diagnosis c. involvement of one joint space in children d. mild to moderate kyphosis in adult 3. Anterior and posterior fusion is indicated in: a. severe kyphosis for solid funsion b. involvement of more than two joint spaces in children to prevent increasing kyphosis c. one stage operation was technically possible and has many advantages 4. Posterior fusion is indicated in: a. poor general condition b. technically difficult cases.

We assessed the accuracy of Goldmann or Schi-(phi)tz tonometric readings in the gas filled vitrectomized eyes. We performed pars plana vitrectomy with or without lensectomy in 8 rabbit eyes, and in 6 enucleated porcine eyes. Fluid-air exchange was done at the end of the procedure. Intraocular pressure was measured using Goldmann tonometer and Schi-(phi)tz tonometer and was compared with true pressure which was monitored by manometer with indwelling catheter in the intravitreal cavity. Goldmann and Schi-(phi)tz tonometry always showed lower presure value than manometeric one(P<0.05) and the discrepancy was greater at higher range of intraocular pressure. Between these two methods Goldmann tonometry was more accurate in the rabbit eye (P>0.05).

The purpose of this study was to evaluate the anatomical outcomes of vitrectomy with internal limiting membrane removal in highly myopic eyes with retinal detachment caused by a macular hole. Nineteen, consecutive, highly myopic eyes with full thickness macular hole with retinal detachment were treated by vitrectomy with internal limiting membrane removal, endolaser photocoagulation on the center of the hole and fluid gas exchange. In five eyes with other peripheral breaks, scleral buckling (3 cases), encircling (1 case) and barrier laser (1 case) were combined. In 15 eyes (79.0%) the macular hole was closed after the initial surgery. In 4 eyes (21%) the macular hole was reopened, but these were successfully treated with fluid gas exchange (1 case) or macular buckling (3 cases). The visual acuity was improved in 15 eyes (79.0%). In conclusion, these results suggest that the removal of the perifoveal internal limiting membrane may be an important adjuvant in the treatment of the myopic macular hole with retinal detachment.

6.Natural Visual Outcome of Submacular Hemorrhage Associated with Retinal Arterial Macroaneurysm.
Journal of the Korean Ophthalmological Society 2000;41(1):119-126
The authors retrospectively analysed epidemiologic characteristics, natural history and visual prognostic factors of submacular hemorrhage 2ndary to retinal arterial macroaneurysm in consecutive 10 patients. All the patients were female with mean age of 64.8 years and with hypertension in most cases.Typically, preretinal hemorrhage over submacular hemorrhage was the usual initial presentation.It took an average 2.9 months for the absorption of submacular hemorrhage.Average visual acuity was counting finger on initial visit and 0.3 on final visit. The initial visual acuity, the extent of submacular hemorrhage and the duration required for the absorption of it were statistically correlated with the final visual acuity[p<0.05]. But it was not the case with the extent of preretinal hemorrhage and the laser photocoagulation to macroaneurysm. As a conclusion, conservative treatment should be considered for the patient with tolerable initial visual acuity and with small extent of submacular hemorrhage 2ndary to retinal arterial macroaneurysm.

7.Clinical Evaluation of Choroidal Detachment Associated with Rhegmatogenous Retinal Detachment.
Journal of the Korean Ophthalmological Society 1995;36(12):2172-2180
Choroidal detachment after retinal detachment surgery is relatively common but preoperative choroidal detachment is very rare. We reviewed three cases of choroidal detachment associated with primary rhegmatogenous retinal detachment to see whether there were common features that may be of help in early diagnosis and treatment. The patients were elderly and presented with markedly decreased vision, profound hypotony and inflammatory cells in anterior chamber. Indirect ophthalmoscopy revealed rhegmatogenous retinal detachment with choroidal detachment and proliferative vitreoretinopathy. They were treated with preoperative and postoperative steroid and undergone surgery including vitrectomy. The follow-up periods were 8, 6 and 2 months respectively. Choroidal detachment disappeared, successful reattachment of retina was achieved and corrected visual acuity was improved in all cases. Choroidal detachment associated with rhegmatogenous retinal detachment seems to be associated with hypotony, intraocular inflammation and unstable vascular system. Careful assessment and proper management including surgical procedure seem to improve its prognosis.

8.The Clinical Evaluation of Atypical Idiopathic Central Serous Chorioretinopathy.
Journal of the Korean Ophthalmological Society 2000;41(3):691-700
Atypical idiopathic central serous chorioretinopathy[ICSC] is a rare disease which is characterized with a bullous retinal detachment and may progress permanent visual loss due to subretinal fibrosis. The authors studied epidemiologic characteristics, efficacy of laser photocoagulation for visual prognosis and duration of serous detachment in 12 patients[17 eyes]with atypical ICSC and in 29 patients[31 eyes]with ICSC. Male predominance was noted in both groups. Bilateral involvement and poor final visual acuity were more prevalent in patient with atypical ICSC[p<0.05], which tends to develop in older age[p=0.128]. Laser photocoagulation shortened the duration of serous detachment in both groups, and improved the final visual outcome in patients with atypical ICSC[p<0.05]. There was no correlation between the duration of ICSC and the extent of serous detachment. In conclusion, more prevalent bilateral involvement and worse visual outcome were the features of atypical ICSC, but laser photocoagulation was effective to improve the final visual outcome and to shorten the duration of the disease.

Little is known about the natural history and management of choroidal neovascularization (CNV) which developed as a complication of laser photocoagulation for central serous chorioretinopathy (CSC). We experienced two patients with CNV which developed after laser treatment for CSC. Submacular membranectomy was performed on both cases after the confirmation of subretinal CNV with optical coherence tomography. One patient received photodynamic therapy for recurrent CNV. The vision of both patients has been improved over 6 months of follow up. These cases suggest that active intervention, including submacular surgery, improves the visual prognosis of this condition.

10.The Effect of Continuous Intravitraal Irrigation(Lavaga) in Experimental Endophthalmitis.
Journal of the Korean Ophthalmological Society 1995;36(11):1980-1989
The prognosis of infectious endophthalmitis has improved considerably in recent years with refinements in early diagnosis, proper antibiotic therapy and vitreous surgery. But the disease is still potentially catastrophic in spite of proper intervention. The purpose of this study was to evaluate the effect of continuous intravitreal irrigation(lavage) after vitrectomy and lensectomy in intractable endophthalmitis. We injected cultured Pseudomonas(1.5 X 10(5)organism/0.1ml) into the anterior chamber or vitreous cavity of 11 rabbits. In both experimental group(8 eyes) and control group(3 eyes), vitrectomy and lensectomy was done 12 hours after inoculation. In the experimental group, silicone tube was installed thru pars plana sclerotomy site as an infusion and drainage port. Vitreous cavity was irrigated for 3 days with normal saline(1000 ml/day) mixed with amikacin (10 mg/day) and dexamethasone(60 mg/day) via this silicone tube. In the control group, we injected 0.1 ml amikacin(100 microgram/0.1 ml) into vitreous cavity at the end of operation and on daily basis for 3 days. Both groups underwent subconjunctival(25 mg/day) and intramuscular (25 mg/kg/day) injection of amikacin for postoperative 3 days. Electroretinograms of two experimental eyes were taken to evaluate retinal toxicity. On postoperative 7th day, all eyes were enucleated to evaluate inflammatory and toxic changes with light microscope. Electroretinograms of experimental eyes became extinguished on the 7th postoperative day. But we observed that the experimental group showed less inflammatory change than control group in the vitreous cavity and retina.
