Achondroplasia is a congenital disorder resulting from a specific disturbance in endochondral bone formation. The ophthalmic features reportedly associated with achondroplasia are telecanthus, exotropia, inferior oblique overaction, angle anomalies and cone-rod dystrophy. This is first report of chorioretinal coloboma in achondroplasia. An 8-year-old female was diagnosed with a developmental delay, known as achondroplasia, seven months after birth. Upon her initial visit, visual acuity was 0.3 in both eyes. The patient had telecanthus but normal ocular motility. Findings were normal upon anterior segment examination. Fundus examination of both eyes revealed about 1,500 microm sized chorioretinal coloboma inferior to the optic nerve head. Upon fluorescent angiography, there was chorioretinal coloboma without any other lesions. Afterward, there was no change in the fundus lesion, and best corrected visual acuity was 0.6 in both eyes. Chorioretinal coloboma is associated with choroidal and retinal detachment. As chorioretinal coloboma and achondroplasia are developmental disorders in the embryonic stage, early detection and regular ophthalmologic examination would be essential in patients with achondroplasia.

PURPOSE: To evaluate the pattern VEP in adult amblyopic patients seen in consultation for ophthalmic evaluation as a past of physical examinations for conscription. METHODS: We retrospectively analyzed, 67 men, 20-year-old or older, who had pattern VEP done for the diagnosis of amblyopia from January 2004 to May 2009. P100 latency and P100 amplitude were analyzed. RESULTS: Thirteen patients were non-amblyopic, and 54 patients had amblyopia. Binocular amblyopia and monocular amblyopia were found in 23 and 31 patients, respectively. In the binocular amblyopic patients, four patients were hyperopic, seven patients were myopic, and 12 patients were astigmatic amblyopia. In the monocular amblyopic patients, 15 patients were anisometropic, 12 patients were strabismic, and four patients had organic amblyopia. The value of P100 latency and P100 amplitude were statistically significantly different between non-amblyopic and amblyopic eyes, with check size of 32x32. However, the types of amblyopia among the patients were not different at a statistically significant level. Visual acuity and P100 amplitude were significantly positively correlated. CONCLUSIONS: VEP might be a useful tool for diagnosis of adult amblyopia, especially using a 32x32 check size. This tool may impart the ability to decide relationship between amblyopia and visual acuity by analyzing P100 latency and amplitude values.

Heat disorders are not uncommon in the military society due to supposedly hard training to overcome the environmental conditions. Twenty-two soldiers with heat disorders were admitted to Chin Hae Naval Hospital June 1969 through July 1970. Hoping that our clinical studies on them contribute to a renewed understanding, the results are reported in summary as follows: 1) Heat disorders occurred with an overall incidence of 3.1 per cent during running in early summer. 2) Of the twenty-two patients, eight (37 per cent) had heat cramps, six (27 per cent) heat exhaustion, five(23 per cent) heat stroke, and three(13 per cent) had undetermined disorder. 3) Ten patients(45 per cent) were comatous, and this occurred most frequently(80 per cent) among those with heat stroke. 4) All patients were grouped into four according to their physical status on admission. Those with heat exhaustion mostly belonged to group I (good) or group II (fair). Those with heat stroke and heat cramps eomprised most of group III (poor) and group IV (grave). 5) Group I and II patients recovered within 12 hours; group III, within 12~24 hours; and group IV, required more than 24 hours of care. 6) One patient with heat stroke, graded V, expired with sudden hypothermia 15 hours following admission. Overall mortality of heat disorders was 4.5 per cent, and that of heat stroke 20 per cent. 7) The rest recovered uneventfully within 19 hours of average.
