PURPOSE: To evaluate the safety, efficacy and technical problems of the endoscopic balloon dilatation of esophageal anomalies in children. METHODS: The medical records of 8 children treated by endoscopic balloon dilatation for esophageal anomalies over a 10-year period at Pusan National University Hospital were reviewed retrospectively. The balloon catheter (Maxforce TTS or CRE, Boston Scientific Co., USA) was positioned across the area of narrowing by direct visualization. The balloon was slowly inflated with normal saline to specified pressures for each balloon and maintained for 60 seconds and then deflated. After 60 seconds pause, the procedure was repeated with a larger sized balloon (increments of 1 mm for each subsequent dilation) till effective dilatation was confirmed by direct visualization without complications. RESULTS: Three male and five female were included and their mean age was 4.2 years. A total of 27 (average of 3.2 per patient) dilatation were performed. Underlying diseases of patients are postoperative stricture of esophageal atresia in 3 cases, esophageal ring in 2 cases, achalasia, corrosive esophagitis and hypertensive LES in one case respectively. The size of initial dilating balloon was chosen on the basis of the diameter of the narrowing determined by endoscopy. The first dilation in patients with severe esophageal stricture was made with a 6 mm sized balloon. Complications observed were esophageal perforation and respiratory holding during the procedure in one case respectively. Successful outcome was seen in 6 patients (75%). CONCLUSION: Endoscopic balloon dilatation can provide a safe and effective mean of treating esophageal anomalies in children and should be considered the treatment of choice in the initial management of those cases.

Aniridia is a relatively rare congenital anomaly and its incidence is about 1:100, 000.Main features of aniridia include congenitally partial or nearly complete absence of the iris and hypoplasia of optic disc and fovea. It is almost bilateral and occurred as an autosomal dominant trait.However, some patients develop both sporadic nonfamilial aniridia and Wilms 'tumor, and another group of patients is transmitted as an autosomal recessive trait. We observed aniridia in two generations, as mother and two daughters. They had cataract, nystagmus, neovascularization of corneal margin and pannus formation, as well as aniridia.We also found hypoplasia of optic disc and fovea in mother. We have operated on mother with phacoemulsified lens aspiration and posterior chamber IOL implantation in both eyes consecutively.The postoperative visual acuity following lens extraction improved, but was not corrected. In addition, intraocular pressure decreased.

A case (female, 34 years old) of pseudotumor cerebri signs with bilateral papilledema and transient diplopia secondary to the use of oral contraceptives is presented. This patient has taken habitually pills (Eugynon E.D.) for over 6 months. By fundoscopy, the moderate degree of papilledema on both eyes were observed with the slight raise of intracranial pressure. But the visual acuity was normal range at first visit day. Periodic ophthalmic examination and the education for side effects of the pills are recommended to women who are taking the pills regularly.

We have attempted to measure parafoveal retinal acuity directly on the exact retinal locus, while observing the retinal image in real time using the scanning laser ophthalmoscope(SLO 101, Rodenstock, Munish, Germany). By the SLO Visumetry software(Rodenstock v. 3.0), thirty eyes of healthy volunteers were examined in 20degrees image field. Using Snellen E as stimulus, the examination was performed from the fovea by the radial pattern. The maximal retinal distance point, which responded to stimulus, was recorded by the pixel, and the distance(mm) from the fovea was calculated by the Bennett formula. The maximum distance from the fovea at the given stimulus size was achieved as follows: 0.32+/-0.01mmat the 15 x15 arc of minute(0.333), 0.63+/-0.01mm at the 17 x17 arc of minute(0.294), 1.05+/-0.03 mmat 20 x 20 arc of minute(0.25), and 1.44+/-0.0 5 mmat the 23 x23 arc of minute(0.217). It was also revealed that the horizontal maximal distance from fovea at given stimulus size was statistically superior to the vertical maximal distance(p<0.05). In conclusion we were able to establish the normal range of parafoveal retinal acuity in healthy volunteers. It may serve as the baseline for subsequent study of retinal pathology and functional evaluation as well as its treatment.

The effect of 0.25% and 0.5% Timolol on intraocular pressure and concentration in aqueous humor was studied after topical instillation in the white rabbit. The intraocular pressure was measured with pneuma tonometer and the Timolol concentration in aqueous humor was measured with High Preformance Liquid Chromatograph after fine needle aspiration of aqueous humor at various time intervals. The results were as follows; 1. The percentage reduction of intraocular pressure increased with time and reached a peak after 3 hours. 2. The concentration of Timolol in aqueous humor increased with time and reached a peak after 3 hours. 3. There was close correlation between intraocular pressure and Timolol concentration in aqueous humor.

The lesions of central nervous system in tuberous sclerosis often calcify, especially those present in the perivascular region, allowing the computed tomography to make early and definite diagnosis, even when patients intelligence was normal, seizures were absent, or clinical findings were not specific, We report three cases of tuberous sclerosis, which showed pathognomic subependymal paraventricular calcification in brain CT.
