The author attempted to discover a method for performing delayed suture adjustment to investigate whether it actually provides more relable and stable results. In order to prevent the fromation of postoperative adhesions and delay the time of adjustment, the author used 0.1mm-thick polyteetraful-oroethylene(PTFE) as a physical barrier. PTFE was placed between the free muscle end and the sclera in 60 strabismic patients during adjustable strabismus surgery. Adjustment was not necessary in eight patients until PTFE removal. In thirteen patients, adjustment was not necessayr after first adjustment until two weeks postoperatively. PTFE was effective in delaying the adjustment after two weeks postoperatively in the remaining 39 patients. To my knowledge, this study represents the longest delayed adjustment in humans. In conclusion, PTFE can be clinically beneficial for delaying the timing of adjustment in strabismus surgery.

Delayed reattachment of the muscle to the sclera may be desirable to correct the deviation of eye developed after the surgery. Based upon the results of the author` s previous experimental study on rabbits, polytetrafluoroethylene was placed around the cut end of the muscle as a physical barrier between the free muscle end and the sclera in seven strabismus patients in order to prevent the postoperative adhesions. Polytetrafluoroethylene (PTFE) was effective in delaying the adjustment more than 2 weeks after surgery in 4 out of 7 patients. In 3 remaining patients, adjustment was not necessary in 2 patients up to 22 days postoperatively because of the desirable postoperative state and suture was lost in a 65-year-old patient. In every case, PTFE was removed after final adjustment. In conclusion, PTFE may be clinically useful for delaying the timing of adjustment.

Epidemiological data on visual disabilities in Korea are rare. In order to partly understand the situation of visual disability in Korea, the authore performed a retrospective study on the major causes and the degree of visual disability of patients who got the authorized document of vusual disability between January, 1993 to June, 1996. Of the 150 patients with availble clinical data, men were more than women(75.3%). The patients in their forties were most common(45 patients, 30.3%). First degree and fourth degree visual disability(4/9) were most common(43.2%, 49.1%) until 1995 and from 1996, respectivelly. Of the 300 eyes, 257 eyes were diagnosed to have visual problems. Optic neuropathy (52 eyes, 20.2%), trauma(31 eyes, 12.1%), retinitis pigmentosa(29 eyes, 11.3%), and corneal opacity (23 eyes, 8.9%) were the common causes of visual disability. These results might be helpful for partly understanding the visual disability in Korea.

PURPOSE: In order to know the outcome in patients with initial overcorrection of 20 delta or more after the surgery of exotropia. METHODS: Sixty-eight patients initially overcorrected 20delta or more following surgery for an exotropia were managed with an alternate full time occlusion, echothiopate iodide, or prism glasses for the period of overcorrection. The alternate prism cover test was performed at near and distance during the follow up period. Reoperation was performed if esotropia of 20delta or more persist more than three months postoperatively. RESULTS: Most patients (87%) had a preoperative deviation of 35 delta or less at distance. Forty nine patients (72%) had 10 delta or less within 4 weeks postoperatively at distance and near, and 11 patients (16%) including 7 patients with prism glasses between five to 16 weeks postoperatively. One patient who was lost to follow up was found to be orthophoric 32 months postoperatively, and another patient refused to come to the hospital for having straight eyes. Four patients with consecutive esotropia and one patient for postoperative hypotropia after combined recession of superior rectus needed a reoperation. One remaining patient was managed with an alternate full time occlusion. CONCLUSIONS: Initial overcorrection of 20 delta or more occurred mostly in patients with a preoperative exotropia of 35 delta or less at distance. Most patients had 10 delta or less within 3 to 4 months postoperatively; however, 6% needed a reoperation for consecutive esotropia.

PURPOSE: To determine the effect of polyurethane with sustained release dexamethasone in delayed adjustable strabismus surgery in rabbits. METHODS: After recession of the superior rectus muscle(SRM), balanced salt solution or polyurethane film with/without sustained release dexamethasone was applied beneath and over the SRM in the control group(group C), polyurethane-steroid group(group P-S) and polyurethane group(group P), respectively. Delayed adjustment was performed once on each SRM at four and six weeks postoperatively by a masked observer. The possible length to adjust and the necessary force required for the adjustment, as well as the degree of any adhesions, were also evaluated. RESULTS: In the control group, adjustment was impossible in all of the eyes at four and six weeks postoperatively. In group P-S, adjustment was possible in 11 out of 11(11/11) eyes four weeks postoperatively and in 10/11 eyes six weeks postoperatively. In group P, adjustment was possible in 9/11 eyes four weeks postoperatively and in 10/12 eyes six weeks postoperatively. In addition, the degree of adhesion was significantly less in group P and in group P-S compared to the control group. The degree of adhesion between the SRM and the sclera was marginally better(p=0.051) in group P-S four weeks postoperatively than in group P. CONCLUSIONS: Use of polyurethane film could delay adjustment in most of the rabbit eyes for up to six weeks postoperatively. Sustained release dexamethasone is helpful for delaying adjustment in rabbit eyes until six week postoperatively without the need for frequent topical instillation of steroids.

We report a false positive case of I-131 scan due to a sialolithiasis in right submandibular gland. I-131 images showed not only remnant thyroid tissues and functional metastases in the anterior neck but also a hot uptake near right submandibular gland. We confirmed the sialolithiasis by radiologic studies. Sialolithiasis should be regarded as a false positive cause when I-131 scan shows a hot spot near salivary bed.

The symptom of crocodile tears refers to an abnormal gusto-lacrimal reflex whereby any stimulus causing parotid secretion also induces lacrimation. It is a sequelae lesion of facial nerve, usually after the facial paralysis. The authors found the symptom of crocodile tears in one case after facial paralysis due to herpes zoster oticus and two cases after Bell's palsy.

BACKGROUND: To access the accuracy and clinical usefulness of microplate identification (ID) system for the identification of Enterobacteriaceae, we compared microplate ID system with API 20E(bioMerieux, Etoile, France). METHODS: Ninety-two cultures of Enterobacteriaceae and one isolate of Aeromonas species were simultaneously identified by microplate ID system and the API 20E. Twenty biochemical tests used in microplate ID system were lactose, sucrose, and H2S in Kligler's iron agar media; indole, sucrose, raffinose, arabinose, trehalose, adonitol, dulcitol, sorbitol, cellibiose, methy-red, phenylalanine deaminase, ornithine decarboxylase, lysine decarboxylase, arginine dihydrolase, urease, and citrate in microplate; and oxidase test. The identification was obtained by considering percent likelihood(% ID), modal frequency and ID score method. RESULTS: Among the 92 cultures of Enterobacteriaceae and one isolate of Aeromonas species, agreement rate of identification according to the % ID between microplate ID system and API 20E were 90.3% to the species level and 97.8% to the genus level. CONCLUSIONS: For the identification of clinical Enterobacteriaceae isolates, the microplate ID system compares favorably with API 20E in identification accuracy and have the advantage of costsaving and easy to use.

Epiblepharon is characterized by horizontal fold of skin adjacent to lid margin. It is a common congenital anomaly, especially in Orientals. In comparison with it, entropion is characterized by an absent lid crease and an inward rolling of the entire eyelid margin. The incidence of the latter was not reported but it was said to be very rare. Not with standing that, congenital entropion has been diagnosed more frequently than epiblepharon in Korea. Supposing that the cases diagnosed as entropion in Korea might fall under the category of epiblepharon on the basis of the authors' clinical experience, the clinical evaluation of the 190 cases operated under the diagnosis of congenital entropion at Seoul National University Hospital from January 1976 to May 1986 was done. The result was that 147 cases(77.4%) were thought to be epiblepharon. So more careful examination might be necessary in diagnosing epiblepharon or entropion in Orientals.
