Enchondroma is a benign tumor mainly developed in the hand and uncommon in the foot. Even if it is in the foot, most are in the phalanges and distal metatarsals of the foot. Enchondroma in the calcaneus is very rare. A 44-year-old male suffered from left heel pain for several months, authors treated it with curettage and bone graft, it was histologically confirmed as an enchondroma in the calcaneus. The authors presented a rare case presentation of an enchondroma in the calcaneus with pain.

PURPOSE: To assess the usefulness and reliability of the IOL power calculation computer program ('POWER!'). METHODS: Calculation times and projected postoperative refractive values of 100 patients with 'POWER!' program were compared with those of the program mounted on the Humphrey R A/B scan system (model 820) by SRK-II and SRK/T formula. RESULTS: There was no significant difference between the projected postoperative refractive values of 'POWER!' program and Humphrey R A/B scan system (paired-t test, p>0.05). Calculation time of 'POWER!' was shorter than that of the program mounted on the Humphrey R A/B scan system incalculating more than 3 sets of IOL (paired-t test, P<0.05) and there was no internal calculation error (ztest, p>0.05). CONCLUSIONS: 'POWER!' is a useful and reliable program for IOL power calculation using SRK-II and SRK/T formula.

BACKGROUND: To investigate the possibie difference, if any, between office blood pressure(BP) and home BP may be important in the diagnosis and treatment of hypersensive patients. This report deails the difference between the two BP's and the usefulness of digital electronic sphygmomanometer(DES) for self-monitoring of home BP. METHODS: The BP's of 14 patients with essential hypertension were measured with mercury sphygmomanometers at outpatient department by physician and with DES at home(twice a day) by the patients. Patients were followed up every 2 weeks for 4 weeks and previous 2 weeks' average home BP's were compared with the office BP's of each 2 weeks' end. RESULTS: There was a significant difference between office and home BP(both systolic and diastolic) ; office average BP(151/95mmHg) was higher than home average BP(136/86mmHg). CONCLUSION: Caution may be needed in the interpretation of office BP unless it is measured several times after adequate rest.

PURPOSE: The effect of superior clear corneal incision and transverse astigmatic keratotomy on the with-the-rule astigmatism in sutureless, small incision cataract surgery was evaluated. METHODS: The postoperative keratometric changes were evaluated in 18 eyes with more than 1.4 diopter (D) of preoperative with-the-rule astigmatism, having sutureless, superior clear corneal incision phacoemulsification. Five eyes over 2.8 D with-the-rule astigmatism also had transverse corneal relaxing incision. Keratometric readings were done within 1 month preoperatively, 1 day and 2 months postoperatively and the changes were statistically analyzed. Simple subtraction method and Cravy method were used for the analysis of astigmatic changes. RESULTS: The mean astigmatism showed decreasing trend, 2.08, 2.25, 1.12 D, within preoperative 1 month, at postoperative 1 day and 2 months respectively and 3.70, 2.48, 2.06 D respectively when transverse keratotomy was added. The reduction of astigmatism was statistically significant at postoperative 2 months (P<0.05; Wilcoxon rank-sum test) and it was more significant with transverse astigmatic keratotomy (P<0.05, Mann-Whitney U test). CONCLUSIONS: The with-the-rule astigmatism over 1.40 D could be reduced in cataract surgery by sutureless, superior clear corneal incision and transverse corneal relaxing keratotomy.

Extracapsular cataract extraction(ECCE) with posterior chamber intraocular lens(PC-IOL) implantation is now favorable surgery to improye decreased visual acuity due to cataract. But this surgical method often causes secondary glaucoma, hyphema, uveitis, and macular edema, which result in poor visual outcome. We studied the causes of elevated intraocular pressure(IOP) retrospectively in 15 eyes of 14 patients among 1,657 cases undergone with the implantation of PC-IOL, in recent 5 years. As the preoperative causes, preexisting uveitis(5 eyes, 33%) and underlying glaucoma(3 eyes, 20%) were important factors. Postoperative causes were newly developed uveitis(1 eye, 6.7%), steroid responder(2 eyes, 13.3%) and idiopathy(4 eyes, 27%). From the above results, We should take more meticulous care in intraoperative and postopertive management in cases of preexisting uveitis and glaucoma.

PURPOSE: To evaluate the effects of wearing rigid gas permeable (RGP) contact lenses on the topographic changes in keratoconus. METHODS: Seventy-seven keratoconic eyes that wore multicurve RGP contact lenses and 30 keratoconic eyes that wore no contact lenses were retrospectively analyzed. The mean follow-ups were 22.6 and 20.5 months in the lens-wearing and control groups, respectively. Visual acuity, comfort, daily wearing time, and corneal staining were evaluated for both groups. The changes in topographic indices were compared between the lens-wearing and control groups. RESULTS: Multicurve RGP lens corrected logarithm of the minimum angle of resolution visual acuity of the lens-wearing group significantly improved from -0.016+/-0.065 to -0.032+/-0.10 at follow-up (p=0.05). In the lens-wearing group with advanced keratoconus, the Sim Kmax, Sim Kmin, apical power, astigmatic index, and anterior elevation significantly decreased from 57.68+/-4.26 diopter (D), 50.50+/-2.32 D, 62.79+/-5.11 D, 7.20+/-0.55 D and 67.36+/-16.30 microm to 55.51+/-4.28 D, 49.62+/-3.26 D, 60.31+/-5.41 D, 5.90+/-0.51 D and 60.61+/-16.09 microm, respectively (paired t-test, p<0.05). The irregularity index of 3 mm did not significantly change. Meanwhile, in the control group, the apical power and irregularity index increased from 55.56+/-7.25 D and 3.06+/-1.68 D to 57.11+/-7.75 D and 3.25+/-1.71 D, respectively (paired t-test, p=0.008, p=0.01). CONCLUSIONS: Properly fitted multicurve RGP contact lenses are not likely to contribute to the progression of keratoconus.

In order to see whether the binocular patching with cycloplegia improves the prognosis in the treatmet of traumatic hyphema, we studied prospectively 77 patients with nonperforating traumatic hyphema who were admitted and treated at the Chonnam University Hospital between January 1994 and July 1995. We analyzed the clearance time of blood clot in the anterior chamber, the incidence of rebleeding and the final visual acuity. The patients were divided into four groups : group I, of 17 patients treated by monocular patching ; group II, of 19 patients treated by monocular patching with cycloplegia ; group III, of 20 patients treated by absolute bed rest with binocular patching ; group IV, of 21 patients treated by absolute bed rest with binocular patching and cycloplegia. The average clearance time of blood clot was 7.4 days in group I, 7.4 days in group II, 6.9 days in group III and 7.5 days in group IV. The incidence of rebleeding was 5.8% (n=1) in group I, 10.5% (n=2) in group II, 0% (n=0) in group III, 14.3% (n=3) in group IV. The final visual acuity of 0.6 or better was achieved in 10 patients (58.8%) of group I, 13 patients (68.4%) of group II, 13 patients (65.0%) of group III, 14 patients (66.7%) of group IV. In the treatment of traumatic hyphema, binocular and monocular groups as well as cycloplegic and non-cycloplegic groups showed no significant difference from each other in the clearance time of blood clot, incidence of rebleeding and the final visual acuity.
