We reviewed 71 cases of recurred retinal detachment after trans pars plana vitrectomy managed with fluid gas exchange with sulfur hexafluoride gas between January 1984 and April 1986 in order to identify the anatomic and functional success rate. The causes of vitrectomy were as follows: retinal detachment with peripheral retinal breaks(29 eyes) or giant dialysis(10 eyes) complicated by proliferative vitreoretinopathy, retinal detachment with no breaks(16 eyes), traction retinal detachments(6 eyes), and others(3 eyes). The anatomic and functional success rate was affected by the grade of proliferative vitreoretinopathy. In 71 cases performed fluid gas exchange with sulfur hexafluoride gas, anatomic success rate was 38%(27/71) and functional sucess rate was 22.5%(16/71).

We report 20 cases of silicone stents intubation in the lacrimal drainage system in 19 patients. Intubation is indicated in the following: congenital dacryostenosis, partial nasolacrimal duct obstruction, and complete nasolacrimal duct obstruction with contracted lacrimal sac. The success rate of silicone stent intubation in congenital dacryostenosis and partial nasolacrimal duct obstuction was 55.5%(5/9). All cases of silicone stents intubation combined with dacryocystorhinostomy were successful, but silicone stents were still placed in lacrimal drainage system in 5 cases. In congenital dacryostenosis and partial nasolacrimal duct obstruction, the silicone stent intubation might be advocated as a conservative alternative to dacryocystorhinostomy and in complete nasolacrimal duct obstruction with contracted lacrimal sac, the silicone stent intubation combined with dacryocystorhinstomy might prevent postoperative canalicular obstruction.

The authors reviewed 250 cases of tumors in the eye and its adnexa diagnosed histopathologirally at the Department of Ophthalmology, Seoul National University Hospital during the last 10 years (Jan. 1976 - Dec. 1985). The results were summarized as follows: 1. The sex distribution revealed 130 males (52%) and 120 females (48%). 2. The tumors of the eye and its adnexa involved the lid 73 cases (29.2%), epibulbar tissue 72 cases (28.8%), the orbit 56 cases (22.4%), and intraocula. tissue 49 cases (19.6%) in decreasing order. 3. There were 159 cases (63.6%) of benign tumors and 91 cases (36.4%) of malignant tumors. 4. The most frequent malignant tumor of the eye and its adnexa was retinoblastoma, and the most frequent benign tumor was nevus. 5. Of the intraocular malignant tumors, the incidence of retinoblastoma was impressively higher than that of malignant melanoma in Koreans. 6. Of the primary malignant lid tumors, the relative incidence of squamous cellcarcinoma and sebaceous gland carcinoma to basal cell carcinoma in Koreanswas high in comparison with that of Caucasians.

Subretinal neovascular membrane in the macula is a major cause of central visual loss. We reviewed the clinical records, fundus photography, fluorescein angiography of the 172 eyes of 166 patients in order to disclose the causes and clinical characteristics of subretinal neovascular membrane and performed argon and krypton photocoagulation in 22 patients. The common causes of subretinal neovascular membrane are idiopathic neovascular membrane, myopic and senile macular degeneration in order(27.1, 26.5, 22.3% aa). There was no significant difference in changes of visual acuity and extent of subretinal neovascular membrane between treatment and non-treatment groups.

A 39-year-old woman has had several episodes of transient right hemiplegia. On neurological examination during the ictal period she had alert consciousness with aphasia, head and eyeball deviation to the right side, and right hemiplegia. Brain MRI was normal. EEG-video monitoring of ictal period showed continuous ictal discharge in the midline frontocentral area coincided with right hemiplegia. After injection of diazepam, the ictal discharge and right hemiplegia disappeared. We report a case of status epilepticus characterized by ictal hemiplegia.

We performed one-stage microsurgical phalloplasty on a 17-year-old male-pseudohermaphroditism patient after bilateral orchiopexy and urethroplasty, using the free radial forearm osteocutaneous sensory flap. The main advantages of this technique are not only the one-stage reconstruction and the satisfactory cosmetic and functional solution, but also the possibility of obtaining normal erogenous and tactile sensibility. One week after the operation, the urethrocutaneous fistula was developed between the native proximal urethra and the constructed neourethra, but seven weeks after the development, it spontaneously healed well. The results of our S-month follow-up are satisfactory in the following respects : 1) satisfactory cosmetic appearance 2) voluntary control of transurethral urination while standing 3) tactile and thermal sensibility. Further follow-up study is necessary for the confirmation of erogenous sensibility, successful sexual life and late complication.

Though diagnosis of myelopathy can be easily made by history and neurological examination, modern technologies, such as MRI and evoked potential study (EPS), have played an important role in making the anatomical and pathological diagnosis of myelopathy. To assess the accuracy of clinical diagnosis and the role of the laboratory studies, we prospectively studied 26 patients with myelopathy, admitted to S.N.U.H. We tried to decide, by clinical history and examination, the anatomical location and the pathological diagnosis, and compared them with final diagnosis. 1. The final diagnosis could be made in 23 out of 26 patients. 2. Of 17 patients with the initial clinical diagnosis of intramedullary lesion (IML), two patients turned out to have extramedullary lesions (EML). Final diagnosis could not be made in three patients, and imaging studies and EPS didn't reveal definite local lesions. In another group of nine patients with the initial clinical diagnosis of EML, three patients had IML. 3. The clinically suspected levels of lesions were shown to be accurate within one level in 20 out of 26 patients after MRI. 4. Clinical diagnosis was accurate in 18 out of 26 patients. 5. Among the laboratory tests, MRI helped localize the lesions and make the final diagnosis. EPS was most helpful in making a diagnosis of multiple sclerosis by finding out asymptomatic second lesions. Even with thorough work-up the etiologies of myelopathy in three patients could not be elucidated. 6. Review of wrong diagnosis showed that diagnostic errors were attributed to incomplete history taking or examination, misinterpretation of clinical data, and unusual presentations or unsuspected rare diseases. Therefore, the authors conclude that the physician's clinical examinations in the diagnosis of neurologic diseases are still valuable despite the technology of the laboratory studies is developing further in present days.

Brain-MR studies are sensitive to intracranial ischemia and vascular flow. However, brain MR study for brain death is clinically limited because keeping the ventilation is difficult during study. In our hospital, three 'brain death patients' brain-MR studies were performed under the anesthetic Mapleson's circuit-F system. Three patients' clinical states were not changed after the studies. We confirmed that brain herniation, absent intracranial flow void, no intracranial contrast enhancement, poor gray/white matter differentiation, and prominent nasal enhancement findings. The value of brain-MR study for brain death may be possible.
