PURPOSE: We retrospectively reviewed the medical records of the patients who had undergone penetrating keratoplasty after glaucoma surgery, to evaluate the surgical outcome of penenetrating keratoplasty associated with glaucoma surgery. METHODS: Twelve patients, 12 eyes were reviewed. Graft status and postoperative intraocular pressure were main outcome measures. And success was defined as thin, clear corneal graft and IOP control between 6 and 21 mmHg after at least 6 month follow-up. RESULTS: The mean age of the patients was 40 year old and male to female ratio was 9 to 3. Mean postoperative follow up time was 12 months for Penetrating keratoplasty and the mean period between glaucoma surgery and penetrating keratoplasty was 12 months. Seventy five percent(9 eyes) maintained clear corneal graft and 67%(8 eyes) showed successful IOP control and both clear graft and IOP control in 58%(7 eyes). CONCLUSIONS: Fifty-eight percent(58%) of our cases showed successful outcome. With the knowledge of better timing for a surgical intervention and an improvement of surgical techniques, there will be an increased success rate.

PURPOSE: To evaluate clinical effects of laser thermal keratoplasty (LTK), LTK was performed in patients with presbyopia or hyperopia. METHODS: LTK was performed in 38 patients who was older than 45 between May and December 2001. Preoperative contact lens fitting and wearing for patients to experience the monovision was tried in all patients for one week. With LTK, we intended patients used dominant eyes for distance vision and nondominant eyes for near vision. Patients' satisfaction, refractive change and near visual acuity were evaluated for least 3 months after surgery. RESULTS: The mean improvement of near vision was 5.16 lines by test with Korean near vision chart. 79% (30 of 38) of patients were satisfied with the results of LTK. CONCLUSIONS: Monovision with LTK is thought to be a good option in patients with presbyopia.

PURPOSE: We schemed to help the therapeutic plan in amblyopic children of old age group by analyzing the clinical outcomes of occlusion therapy in amblyopic children more than 8 years old. METHODS: In 104 unilateral amblyopic children whose occlusion therapy had been finished, the retrospective study was performed. The average age at the beginning of treatment was 5.9 years (1.2~15.2 years). We divide the patients into three groups on the basis of age at the beginning of treatment: below 4 years (group 1, N=41), 5~7 years (group 2, N=44), more than 8 years (group 3, N=19). The success rate of occlusion therapy in group 3 was compared with the success rate of other groups, and the clinical features of group 3 were analyzed. RESULTS: The success rate of occlusion therapy in group 3 (68.4%) was significantly low compared with other groups (p<0.05). In group 3, the success rate of anisometropic amblyopia (90.0%) was significnatly higher compared with the success rate of strabismic amblyopia (44.4%)(P<0.05), and it was similar to the success rate of anisometropic amblyopia of other groups. CONCLUSIONS: The success rate of occlusion therapy in amblyopic children more than 8 years old was significantly lower compared with other groups. But the clinical outcomes were fair, especially in anisometropic amblyopia. We suggest to enforce occlusion therapy in amblyopic children more than 8 years old.

Vertebral artery hypoplasia (VAH) can be easily overlooked if the contralateral side vertebral artery is intact, because of compensation by the contralateral artery or cerebral collateral network. The clinical relevance and hemodynamic impact of VAH is still controversial. However, VAH has recently been considered a risk factor for posterior circulation ischemia. Ischemic stroke is seldom caused by free floating thrombi (FFT) in the artery. Pathophysiology of FFT has not yet been clarified. The state of reduced blood flow such as a vertebral artery origin stenosis may cause FFT. Their instability may make them sources of recurrent artery to artery embolism. Patients with FFT will require appropriate medical and endovascular treatment. The current case illustrates a short-term angiographic change of spontaneous thrombolysis of VAH and multiple thrombi at the distal region of the stenosed lesion after stent-assisted angioplasty for a vertebral artery origin stenosis.

The authors attempted to analyse the factors influencing the mortality involved in aneurysm surgery based on 38 cases of intracranial surgery for anterior communicating aneurysms, and obtained the following conclusion. 1. The surgical results are much better when the aneurysm surgery is delayed over one week after the occurrence of aneurysmal rupture, if there is no evidence of intracerebral hematoma. Administration of a massive dosage of epsilon aminocaproic acid in the waiting period prior to aneurysm surgery seems to be effective for preventing recurrence of bleeding from the aneurysm. 2. The direction of the anterior communicating aneurysm should be clearly visualized on a cerebral angiogram so that the most effective aneurysmal approach can be selected in surgery. 3. Microsurgery and hypotension in aneurysm surgery minimize brain damage in the exposure of aneurysm and provide accurate isolation of the aneurismal neck from the parent vessel in aneurysmal neck ligation. 4. Proximal ligation of the anterior cerebral artery is also an effective procedure to prevent recurrent hemorrhage from anterior communicating aneurysm.
