Purpose: To report a case with corneal decompensation in a patient of pseudoexfoliation syndrome.Case summary: A 70-year-old woman was referred to our clinic to evaluate decreased visual acuity in the right eye. She had no history of previous ocular surgery or laser treatment. The best corrected visual acuity was 0.5 in both eyes. The patient had diffuse corneal edema in the epithelium and stroma in the right eye. The left eye showed diffuse endothelial pigment deposits. Deposition of pseudoexfoliation material on the iris and anterior lens capsule was observed in both eyes. The intraocular pressure was 15 mmHg in both eyes without treatment. Specular microscopy was limited in the right eye due to the corneal edema and the left eye showed endothelial cell loss, increased pleomorphism, and atypical guttata. Anterior segment optical coherence tomography revealed irregular thickening of the corneal stroma and protrusion of Descemet’s membrane in the right eye. Conclusions In patients with pseudoexfoliation syndrome, corneal decompensation can occur without intraocular pressure elevation and glaucomatous damage.

OBJECTIVE: To evaluate the efficacy of prenatal multiplex PCR with chorionic villi, in the case of family history of DMD due to exon deletion. METHODS: DNA was extracted when cells' size are 1x 106 on T- flask surface area reach to 25 cm2 after 2 weeks from sex confirmation. Average DNA concentration was 50-100 ng and multiplex PCR test was performed from DNA extraction. RESULT: PCR was done for 17 exons devided into 4 groups. Seventeen exons were all amplified with their right size. CONCLUSIONS: This method is DNA analysis for prenatal diagnosis of DMD with chorionic villi in the family of DMD. This is useful when preimplantation genetic diagnosis is not available.

The results of rotation chair test were known to variable by many parameters such as eye opening and alertness, etc. The situational change in rotation chair test must be considered to interpretation of its result. But in Korea, there were no reports or articles about parameters which influence the result of rotation chair test. So, we assumed that eye opening and alertness were main parameters and took rotation chair test in neurotologically normal subjects. For evaluation of the effect of eye-open or eye-closure and alertness on the rotational vestibular stimulation, we have taken sinusoidal harmonic acceleration test in 30 otoneurologically normal subjects. The maximal slow phase eye velocity, gain and asymmetry were obtained and compared with each other in four different conditions with properly fixed conditions such as in darkness and 0.05Hz frequency. At least five minutes interval was given between the tests and recalibrations were done before each tests. The results of this test were as follows. 1) Vestibular-ocular reflex(VOR) changes according to eye open or closure. In cases of examinees which were given alerting tasks, larger gain was obtained with eyes opened than with eyes closed, and that was statistically significant(p<0.05). In cases of examinees which were not given alerting tasks, larger gain was obtained with eyes opened than with eyes closed, but that was not statistically significant(p>0.05). 2) VOR changes according to alertness. In cases of examinees which opened their eyes, larger gain was obtained with alerting tasks than without alerting tasks, and that was statistically significant(p<0.05). In cases of examinees which closed their eyes, larger gain was obtained with alerting tasks than without alerting tasks, and that was statistically significant(p<0.05). 3) There was no significant changes of asymmetry according to the conditions. Therefore, from above results, we recommend the condition in which examinees open their eyes and be given alerting tasks as one of the optimal condition in sinusoidal harmonic acceleration test.

Craniosynostosis is a congenital deformity causing disorder in the growth of the skull and brain parenchyma, resulting from the fusion of the cranial sutures of calvaria or basilar before birth or within a few months after birth. In most cases it is diagnosed just after birth. However, some cases of vague diagnoses were reported, which was due to the late onset age, and the absence of typical symptoms and typical radiological findings. We make a report of a case in which the three-dimensional CT was helpful in making a diagnosis of a patient with minimal forms of craniosynostosis having minimal cranial deformities revealing just late onset raised intracranial pressure, along with the investigation of medical literature.

This case describes a tracheal stenosis complicated by endobronchial truberculosis. A 50-year-old female with progressive dyspnea was referred to us for the management of long segmental tracheal stenosis. Treatment modalities for tracheal stenosis include open surgical resectin and reconstruction, mechanical dilation, laser resection, and placement of an airway prosthesis. The following is a report of a successful treatment of a long segmental tracheal stenosis through a tracheal augmentation and the use of al Bovine pericardium. This technique may provide a relief from tracheal stenosis.
