Mucormycosis is a fungal disease in which normal saphrophytic molds produce an acute and often rapidly fatal infection. Patients with orbital mucormycosis commonly present with abrupt visual loss, orbital pain and facial hypoaethesia. In our case, mucormycosis was confirmed by histopathological examination and it was mainly treated with daily intravenous amphotericin B for 42 days. As medical treatment was successful, no orbital exenteration has been necessitated.

PURPOSE: The purpose of this paper is to discuss the characteristic CT and MR findings in persistent hyperplastic primary vitreous(PHPV) and to compare the detectability of those findings in each modality. MATERIALS AND METHODS: We retrospectively evaluated CT and MR findings in 32 patients with PHPV. Twenty-five patients had CT, 13 patients had MR, and 6 patients had both CT and MR. RESULTS: Major findings of PHPV in 32 patients on both imaging modalities were lens deformity(78%), shallow anterior chamber(72%), heterogeneous vitreous opacity(72%), enhancing hyaloid artery or remnant of fibrotic hand(69%), and microophthalmos(67%). Minor findings were retinal detachment(22%), and vitreous hemorrhage(6%). In MRI, lens deformity(92%) and shallow anterior chamber(85%) were detected most commonly whereas in CT, opaque vitreous(80%) was the most common finding. Findings of enhancing hyaloid vessel or remnant of fibrotic band, considered characteristic of PHPV, were more commonly detectable in MR (85%) than CT(52%). CONCLUSION: Characteristic MR and CT findings of PHPV were lena deformity, shallow anterior chanber, heterogeneons vitreons opacity, enhanciny hgalind artery or remnant fibrotic band, and microphthalmos. MR seemed to be more useful than CT in detecting Globe pathology.

Nd-YAG laser is known as a safe and effective treatment for posterior capsular opacity after cataract surgery. We studied the ocular complications after Nd-YAG laser treatment in uveitis patients. From January 1991 to December 1996, we retrospectively investigated the complications of uveitis in 22 persons(25 eyes) after Nd-YAG laser posterior capsulotomy, and also investigated that of nonuveitis in 563 persons(635 eyes) as a control group. The uveitis cases consisted of six anterior uveitis, eight intermediate uveitis, seven Behcet`s syndromes, three panuveitis, and one posterior uveitis. In the uveitis group, the complications(18 eyes) consisted of three retinal detachments, one giant retinal tear, three glaucoma, two aggravations of uveitis, two vitreous opacities, one retinal emorrhage, one proliferative vitreoretinopathy, one hyphema, and four transient high intraocular pressures(IOP), and in the control group, it consisted of two subluxations of intraocular lens(IOL), three glaucomas, one retinal tear, three transient high IOPs, two vitreous opacities, two retinal hemorrhages, three macular holes, two retinal detachments, and five cystoid macular edemas. From our experience, the incidence of complications after Nd-YAG laser posterior capsulotomy in uveitis was higher than that in nonuveitis. It was also noted that it is necessary to follow up thoroughly the complications after Nd-YAG laser posterior capsulotomy in uveitis patients.

A chemical analysis of subretinal fluid was made in 15 patients (16 eyes) who had undergone retinal detachment surgery from March 1, 1991 to July 31, 1991 at St. Mary's Hospital, Catholic University Medical College. The protein concentration of subretinal fluid ranged from 1.0gm/dl to 7.1gm/dl, and the average protein concentration of subretinal fluid of retinal detachment for 90 days or more showed 5.13 +/- 1.71gm/dl and that of subretinal fluid of retinal detachment for less than 90 days was 2.06 +/- 1.29gm/dl. This revealed increasing tendency of protein concentration in proportion to the duration of detachment (p<.05), and the protein concentration of subretinal fluid did not show any differences according to the size of retinal detachment. Sugar ranged from 32mg/dl to 96mg/dl, and chloride was from 92mEq/L to 126mEq/L. From this study, we found that the protein concentration of subretinal fluid increased in proportion to the duration of retinal detachment. On the contrary, sugar and chloride concentration was not related to the duration of retinal detachment.

Background; Tracheal intubation for cesarean section is usually performed with rapid sequence induction. Under this light stage of anesthesia, marked hypertensive changes of maternal hemodynamic responses following tracheal intubation may occur, which are the common cause of maternal and neonatal complications. We have studied the maternal cardiovascular blunting effect of magnesium sulfate following tracheal intubation in cesarean section. Methods; After obtaining the written informed consents, ninety ASA class I parturients scheduled for cesarean section were randomly allocated to one of three groups: group 1 received thiopental 4 mg/kg and succinylcholine 1.5 mg/kg, group 2 received fentanyl 1.5 microgramg/kg additionally, and group 3 received fentanyl 1.5 microgramg/kg and MgSO4 40 mg/kg additionally. Systolic, mean, diastolic blood pressure, and heart rate were measured before induction, immediately after intubation. Serum magnesium concentrations were measured before administering magnesium and near the end of surgery. Train of four ratio was monitored during whole period of anesthesia. Neonatal Apgar scores and neurologic and adaptive capacity scores (NACS) were checked. Results; Blood pressure changes were more stable in group 2 and group 3, especially group 3, than group 1 (p<0.05). No statistical differences were found in heart rate changes in all groups. No significant differences were noted in neuromuscular recoveries, neonatal Apgar scores and NACS. Conclusions; Magnesium sulfate may be successfully used for blunting the cardiovascular response to tracheal intubation in parturients undergoing general anesthesia for cesarean section.

Oculopharyngeal muscular dystrophy, one of the variants of chronic progressive external ophthalmoplegia, is a disorder characterized by progressive bilateral ptosis, immobility of the eyes and dysphagia. We have experienced a 46-year-old woman complaining of bilateral ptosis, mild dysphagia and immobility of the eyes. Oculopharyngeal muscular dystrophy was confirmed by clinical, electromyographic and histopathologic examination. Therefore, we report a case of oculopharyngeal muscular dystrophy with review of literatures.

PURPOSE: To compare the decentration, tilt and anterior chamber depth between aspheric AcrySof(R) IQ IOL (SN60WF) and spheric AcrySof(R) Natural IOL (SN60AT). METHODS: The subjects of this study consisted of 22 patients (26 eyes) using an aspheric AcrySof(R) IQ IOL and 26 patients (31 eyes) using spheric AcrySof(R) Natural IOL. All lenses were inserted into the capsular bag after 5 mm continuous curvilinear capsulorhexis and phacoemulsification. The decentration, tilt and anterior chamber depth of both IOLs were measured on the 1st, 30th and 60th postoperative day using an anterior eye segment analysis system (Scheimpflug camera, EAS-1000, Nidek, Japan). RESULTS: There was no statistically significant difference in the decentration between the IQ IOL and Natural IOL on the 1st (p=0.05), 30th (p=0.09) and 60th (p=0.06) postoperative day. There was a statistically significant difference in tilt between IQ IOL and Natural IOL on the 1st (p=0.000053) and 30th (p=0.018) postoperative day. However, there was no statistically significant difference in tilt on the 60th postoperative day (p=0.05). The anterior chamber depth of IQ IOL was decreased, but was not statistically significant on the 1st (p=0.10), 30th (p=0.07) or 60th (p=0.06) postoperative day. CONCLUSIONS: There were no significant differences between AcrySof(R) IQ IOL and AcrySof(R) Natural IOL in decentration, tilt or anterior chamber depth, showing that posterior aspheric surface causes little effect on the IOL stability.
