We analyzed postoperative astigmatic changes according to the location of incision in 129 eyes that sutureless cataract surgeries were performed. We followed up the astigmatic changes until six months postoperatively, and compared the results of two groups of which the one is the preoperative against-the-rule astigmatic cases with superior incisions and temporal incisions, the other is the preoperative oblique astigmatic cases with superior incisions and superotemporal incisions. In the preoperative against-the-rule astigmatic cases, postoperative astigmatic changes were shifted toward against-the-rule astigmatism(0.23 diopters) in superior incisions and toward with-the-rule astigmatism(0.20 diopters) in temporal incisions until 6 months following surgery(p<0.01). Surgically induced astigmatisms were also less for in temporal incisions than superior incisions(p<0.01) and corneal astigmatisms were stabilized after two weeks postoperatively in both groups(p<0.05). In the preoperative oblique astigmatic cases, postoperative astigmatic changes were shifted toward against-the-rule astigmatism(0.63 diopters) in superior incisions and also toward against-the-rule astigmatism(0.46 diopters) in superotemporal incisions until 6 months following surgery(p>0.05). Surgically induced astigmatisms were less in superotemporal incisions than superior incisions (p<0.01) and corneal astigmatisms were stabilized after one month postoperatively in both groups(p<0.05). These results demonstrated that surgically induced astigmatisms were decreased by the incision at steep axis, and in the cases of preoperative againstthe rule astigmatism, the preexisting astigmatisms were decreased by the temporal incisions.

We analyzed an astigmatism and an uncorrected visual acuity in 235 eyes for 6 months following sutureless cataract surgery(167 eyes) with 5 mm(Group 1), 6 mm(Group 2), and 7 mm(Group 3) incision lengths at 2.5 mm posteriorly from the corneoscleral limbus, and shoelace sutured cataract surgery(68 eyes) with 7 mm(Group 4) incision length at 1 mm posteriorly from the corneoscleral limbus performed by one surgeon. In three groups of sutureless cataract surgery, the surgically induced corneal astigmatisms were stable after one month postoperatively, but decreasing the length of incision substantially reduced the astigmatic changes(p>0.05), the astigmatic swings(p>0.05) and the astigmatic ranges. In comparison to sutured cataract surgery with 7 mm incision length, sutureless cataract surgery with same incision length reduced the astigmatic changes(p<0.01), reduced the astigmatic swings(p<0.01) and narrowed the astigmatic ranges and also was stabilized earlier. The shorter the length of incision in sutureless cataract surgery, the higher the incidence of an uncorrected visual acuities of 20/40 or better(p>0.05) was noted. In comparison to sutured catarct surgery with 7 mm incision length, suture less cataract surgery with same incision length had higher incidence of an uncorrected visual acuities of 20/40 or better(p<0.01). The tesults indicate that smaller incision length in sutureless cataract surgery was associated with a lower surgically induced astigmatism(p>0.05) and a better uncorrected visual acuity(p>0.05). And sutureless cataract surgery rather than sutured cataract surgery was associated with a lower surgically induced astigmatism(p<0.01), an earlier stability, and a better uncorrected visual acuity(p<0.01).

PURPOSE: To report a case of a drug-resistant Penicillium endophthalmitis that was treated with intravitreal voriconazole injection. CASE SUMMARY: A 73-year-old male who developed endophthalmitis after cataract surgery was treated with intravitreal vancomycin and ceftazidime injection after aqueous and vitreous cultures were done. The condition were not improve after intravitreal injection, and the culture showed Penicillium species. Fungal endophthalmitis was diagnosed and pars plana vitrectomy, intraocular lens removal, and intravitreal amphotericin B injection were performed. However, a progressive worsening of the ocular condition was observed, and the patient was transferred to our hospital. At initial visit, the best corrected visual activity was hand movement. The hypopyon and thick exudative membrane filled the anterior chamber. Pars plana vitrectomy and intravitreal voriconazole injection were performed under the diagnosis of drug-resistant Penicillium endophthalmitis. The condition improved after the operation, and there was no recurrence of endophthalmitis until four months after vitrectomy. CONCLUSIONS: Voriconazole is useful in the treatment of drug-resistant fungal endophthalmitis.

We evaluated pseudophakia in high myopic patients whose an axial lenght were 26mm and over. Cataract surgery was performed with ECCE and posterior chamber intraocular lens implantations from May 1986 to May 1991 on 69 patients (80 eyes). The results were as follows; 1. Most myopic patients were good candidates for posterior chamber intraocular lens implantation regardless of axial length. 2. Posterior chamber intraocular lens implantations in high myopia were a good refractive surgery. 3. The theoretical formula had better predictabilized than the empirical formula in apredictive accuracy.

PURPOSE: To report optical coherence tomography (OCT) findings in albinism. METHODS: Full ocular examinations, including OCT, were performed in one patient with ocular albinism and two patients with oculocutaneous albinism. RESULTS: OCT scans were unable to detect the foveal depression in these patients. A widespread thickening of the retina occurred throughout the entire fovea, which showed no difference from the surrounding macula. OCT scans also demonstrated probable scleral layer below the retinal pigment epithelial (RPE) layer. CONCLUSIONS: OCT scans of albinism patients confirmed foveal hypoplasia and increased transmission of incident light in the RPE layer.

Swallowing caustic materials may produce full-thickness burn and loss of esophageal function. Caustics, both acid and alkalis, can corrode and destroy living tissue. Full-thickness burn of esophiageal epithelium causes severe stricture which frequently requires surgical repair. Recently, non-operative dilatation of luminal stenosis has been utilized. Esophageal endoscopic endoprosthesis has been used widely in malignant esophageal stricture but not in benign stricture. In recurrent benign esophageal stricture following repetitive balloon dilatation, we experienced a case of an 18-year-old woman with severe stricture which was successfully managed by esophageal endoprosthesia So we report this case with the review of the literature.

PURPOSE: inhaled nitric oxide(iNO) is an excellent method for the postoperative pulmonary hypertension in congenital heart disease. But more detailed care is needed because of the development of rebound pulmonary hypertension after NO Withdrawal. We performed this study in order to discontinue the iNO successfully by way of presenting the adequate weaning and supplying methods. METHODS: Between January, 1998 and August, 1999 we sudied 10 patients who had rebound pulmonary hypertension(RPH) after iNO withdrawal. We completed the iNO in these patween the first the second trial of the weaning process. We tried to discover the differences between the first and second weaning process. We measured NO concentration at the start and just before NO withdrawal and during the period of weaning process. Moreover, to identify the iNO effects during the weaning of the iNO, we counted the degree of the change of PaO2/FiO2and mean PAP/SAP beween initial and at half of the initial NO concentration. RESULTS: Second weaning had a longer duration weaning process(11+/-0 cersus 5+/- hours, P<0.05), lower NO concentration just before NO withdrawal(2+/-.6 versus 4+/-ppm, P<0.05). In the change of the mean PAP/SAP and PaO2/FiO2as iNO was weaning from the initial iNO concentration to a half of the initial iNO concentration, the degree of increase in mean PAP/SAP(0.026+/-.07 versus 0.054+/-.07, P<0.05) and the degree of decrease in PaO2/FiO2(49+/-4 versus 65+/-2, P<0.05) were smaller in the second in the second weaning process than the first weaning process. CONCLUSION: A successful weaning of iNO can be performed with a low iNO concentration at the start and just before withdrawal and with the long duration iNO weaning process. Moreover, We speculate that the degree of change in the mean PAP/SAP and PaO2/FiO2at the half of the iNO weaning process are an indicator for the development of RPH.

OBJECTIVE: Brachial plexus injury can produce a intractable chronic neuropathic pain. This study was undertaken to assess the long term outcome of microsurgical dorsal root entry zonotomy(MDT). METHODS: Between October 1997 and December 2002, 21 patients received MDT because of a intractable pain resulting from brachial plexus injury. Of these, 19 patients were followed for more than 2 years. Fourteen of 19 patients were male and patient ages ranged from 22 to 69 years. Mean pain duration was 36.8 months and all patients had severe pain of 9~10 visual analogue scale. To achieve complete destruction of abnormal dorsal horns, thermocoagulation of the posterolateral sulcus were performed and careful gluing was done to prevent postoperative adhesion and pain recurrence. RESULTS: Of the 19 patients, 15 patients had excellent (>75% reduction in pain) and good (51~75% pain relief) results in a average postoperative period of 4.1 years. One patient had a poor (less than 25% pain relief) result. Three patients were considered to have a fair result (26~50% pain relief). Postoperative complications were 2 transient ipsilateral ataxia and 1 CSF fistula that resolved without surgical revision. CONCLUSION: These results indicate that MDT provides excellent long-term pain relief in medically intractable chronic neuropathic pain following brachial plexus injury without significant complications.
