The omentum has been used over the years for a variety of clinical problems. Recently it has shown that placing the omemtum on the brain and spinal cord can lead to an extensive development of vascular connections at the omental/CNS interface. Success with omental transposition to the human brain has led to increasing intreast in placing the omentum onto the human spinal cord. One paraplegic patient was chosen to enter into a feasibility study to see if omental transposition to their spianl cord might result in clinical benefit. The length of time from injury was about 21 months respecively. This patient had little, if any, motor and sensory function below umbilicus level. The operation required surgical lengthening of the pedicled omentum followed by its placement into a subcutaneous tunnel created backward along the lateral chest wall up to T-10, 11 level. An extensive thoracic laminectomy was then performed followed bya wide opening of the dura. In our case the cord showed segmental shrinkage of the spinal cord consistent with previous trauma. The omentum was laid directly onto the underlying spinal cord. Our observation for five months has shown that placement of the omentum onto the chronically injured spinal cord allowed for subsequent improvement in neuroelectrical activity, as manifested by reproducible somatosensory evoked potentials, and, more importantly, in moter function. It is considered that placing the omentum directly upon the brain or spinal cord may have the effect of either improving local vascular perfusion or, possibly, exerting some biochemicals(neurotransmitter), or as yet unknown, influence. But further observation is warranted to determine whether this improvement will be continued and will be observed in another cases.

Focal brainstem encephalitis due to Herpes simplex virus if a very rare infectious disease, occurs with a frequent of 1-2 million population per year. A 3 years old girl is described with infection due to Herpes simplex virus causing brainstem encephalitis. The diagnosis was established by enzyme immunosorbent assays of the cerebrospinal fluid and serum which demonstrated antibody responsed to Herpes simplex virus. The clinicopathological features, radiological findings, laboratories and brainstem biopsies are discussed in the context of the literature.

Many of the thoracolumbar spine fracture may be managed conservatively by postural reduction. But postural reduction alone cannot treat all the patient with thoracolumbar spine fracture properly. Recently, more patients with thoracolumbar spine fracture are managed surgically with the advance of surgical technique and instrument. Surgery may be performed by either anterior or posterior approach according to many factors. Generally initial management of patient with thoracolumbar spine fracture is conservative and surgery is delayed for spinal fusion, but early surgery with decompression of spinal cord and fusion of the vertebral body seems to be more proper in unstable fracture with compression of spinal cord by bony fragment and incomplete neurological deficit. Authors analyzed 52 cases of thoracolumbar spine fracture and made a proper management plan and proper surgical approach.

The pattern reversal visual evoked potential(PRVEP) and flash electroretinogram(flash ERG) were performed in 22 patients with optic atrophy. Patients with ophthalmologic problems other than optic atrophy or with systemic disorders were excluded from the analysis The results are as follows: 1. In the 41 eyes of patients with optic atrophy, 39 of them showed abnormal PRVEP, in which all the eyes had no consistent waveform except in one patient 2 eyes with delayed P1 latency. 2. 13 eyes were abnormal in both PRVEP and flash ERG but no eye was abnomnal in flash ERG only 3, Regarding the flash ERG examination, 13 eyes were abnomlal. Of these, there was a period of 1 to 2 years for 1 eye's disease, a period of 2 to 5 years for another eye' disease and after 5 years 11 eyes were diseased. Therefore, it showed that the longer the duration of disease lasted, the more flash ERG abnormalities developed. 4. The abnormalities of PRVEP haxe no significant relationship with the duration of the disease.

PURPOSE: To investigate the preoperative factors affecting the visual outcome after a vitrectomy in a rhegmatogenous retinal detachment (RRD). METHODS: A retrospective study of 79 eyes was carried out. The 41 eyes were macula-off RRD (group I), the 38 eyes were macula-on RRD (group II). The preoperative factors examined in this study included the preoperative best corrected visual acuity (BCVA), age, the duration of macular detachment, the extent of the detached retina, the delay of operation. The correlation between these factors and the postoperative 6 months BCVA were investigated. RESULTS: In group I, preoperative BCVA (r = 0.313, p = 0.037) and preoperative retinal detachment (RD) extent (r = 0.483, p = 0.001) were significantly correlated with postoperative 6 months BCVA. In group II, preoperative BCVA and preoperative RD extent were not significantly correlated with postoperative 6 months BCVA. Regardless of including macula, the patient's age, duration of symptom and delay of operation after clinic visit were not affected to the visual outcome. Patients with symptom duration of 7 days or less achieved better final BCVA (0.36 ± 0.45 log MAR, n = 29) than patients with longer symptom duration (0.79 ± 0.55 log MAR, n = 16) (p = 0.008). CONCLUSIONS: After vitrectomy for macula-off RRD, the factors related to favorable visual outcome were the better preoperative BCVA, the less extent of the detached retina. And surgical repair within 7 days of the symptom onset yielded better visual outcomes. Otherwise, in macula-on RRD, preoperative BCVA, age, the duration of retinal detachment, the extent of the detached retina, the delay of operation did not impact on visual outcome.

PURPOSE: To evaluate long-term change in intraocular pressure (IOP) in eyes undergoing laser iridotomy (LI) and early phacoemulsification after LI in patients with acute angle-closure glaucoma (AACG). METHODS: The retrospective, comparative chart review included patients with AACG, Group A who underwent only LI and Group B who underwent early phacoemulsification within 1 month after LI. Patients were followed up on day 1; week 1; and months 1, 3, 6, and 12 after LI. IOP changes were studied. RESULTS: This study included a total 99 eyes from 99 patients, 37 in group A and 62 in group B. The mean IOP were not significantly different between the two groups at the initial visit or 1 month later. However, group B showed a consistently lower mean IOP that that of group A at 3, 6, and 12 months (p= 0.003, <0.001, <0.001, respectively). The prevalence of IOP increase to greater than 21 mmHg was 3 (8.11%), 5 (13.51%), and 5 patients (13.51%) in group A and 0, 2 (5.41%), and 1 patients (1.61%) in group B at 3, 6, and 12 months, respectively. Group B showed a significantly lower prevalence of IOP increase (p = 0.050, 0.038, 0.026). CONCLUSIONS: We found that patients treated with early phacoemulsification after LI had better outcomes of well-maintained IOP compared to those undergoing LI alone. For AACG patients with coexisting cataract, early phacoemulsification after LI can be considered as a reasonable treatment to maintain IOP.
