Aniridia or irideremia is characterized by reduction of iris or absence of total iris, but a rudimentary iris is always present in most cases. This congenital anomaly is familial and the transmission is strongly dominant by an autosomal gene. It demonstrates high penetrance and variable expression. Aniridia is mainly due to a primary defect in development of the neural ectoderm and an aberrant development of the mesoderm. Glaucoma and cataract in the eye is frequently complicated with other deformities of the body and the treatment is not satisfactory. The author have experienced a case of aniridic family which is composed of 7 persons. Of these, the father, one son and 3 daughters are affected with aniridia, cataract, nystagmus and amblyopia and the mother and one son are healthy. The author reports this cases with the review of literature.

PURPOSE: We performed this study to evaluate the occurrence of consecutive esotropia after early surgery in the patients with intermittent exotropia less than 4 years of age. METHODS: We analyzed the surgical results of 37 patients who underwent surgery before 4 years of age retrospectively. They were followed up at least more than 1 year after surgery. The orthophoria was defined as an exophoria of 0 to 12PD or an esophoria of 0 to 5PD after surgery. The consecutive esotropia was defined as an esodeviation lasting more than 3 months that needed surgical correction due to sensorial deterioration. RESULTS: Preoperative angle of exodeviation at distance ranged from 20PD to 60PD (mean 35.1 +/- 9.2PD). Twenty-seven of 37 patients (75.7%) showed orthophoria after surgery in 1 year follow-up and 20 of 31 patients (64.5%) in 2 years follow-up. Five patients (13.5%) showed recurrence and 4 patients (10.8%) consecutive esotropia. Immediate postoperative overcorrection was 14.1 +/- 8.7PD(0-30) in patients who were orthophoric after postoperative follow-up more than 2 years. The rate of consecutive esotropia was high in patients with an exo-angle of 30PD or more and a large amount of recession of lateral recti more than 7mm. CONCLUSIONS: This study revealed that consecutive esotropia after early surgery for intermittent exotropia less than 4 years of age was noted to the 10.8%.

The authors present a case of macular dystrophy of the cornea which is inherited as a recessive trait. The patient was 43 years old female housewife who had suffered from photophobia, frequent tearing, foreign body sensation and gradually increasing visual dimness since early childhood. Partial penetrating keratoplasty was performed. We had a study of the histopathologic findings for a case of macular dystrophy of the cornea with a brief review of relating literatures.

PURPOSE: To determine proper position of lateral gazes and angle of head turn for the measuring lateral incomitancy in intermittent exotropia. METHODS: Twenty-five Korean intermittent exotropes with exoangle more than 25 prism diopters (PD) and 25 orthophoric people were taken. Three lateral gazes were proposed: position A, when the lateral limbus of the abducted eye was off the lateral canthus; position B, when touched the lateral canthus; and position C when was hidden behind the lateral canthus. The angle of deviation and head turn were measured at each position. In the most comfortable position which subjects selected, the length from lateral canthus to lateral limbus (lateral cantho-limbal distance) of the abducted eye was measured. RESULTS: 23 patients of each group selected that position A was the most comfortable. At position A, the mean of cantho-limbal distance in exotropes was 1.19mm at the right lateral gaze and 1.04 mm at left, people with orthophoria showed larger values in both gazes. The average amount of head turn was 24.1 degrees at the right lateral gaze and 24.3 degrees at the left at position A, 27.5 degrees and 34.1 degrees at position B, 27.6 degrees and 33.7degrees at position C. The average angle of exodeviation was 27.4 PD in the primary gaze. It was 21.7 PD in the right lateral gaze and 20.3 PD in the left lateral gaze at position A, 17.9 PD and 17.5 PD at position B, and 9.0 PD and 8.6 PD at position C. CONCLUSIONS: In the measurement of lateral exo-angle to evaluate lateral incomitancy in intermittent exotropia, the most appropriate position of eye and head turn turned to be when the lateral limbus of the abducted eye is about 1mm apart from the lateral canthus with head turn of 25degrees laterally.

We studied 49 patients who showed partially accommodative esotropia retrospectively. They were glasses for accommodative component and underwent surgery for nonaccommodative one. The mean value of refractive error was +4.41 +/- 2.04 D. The mean deviation angle of accommodative component was 20.78 +/- 12.59 PD (prism diopter), and the one of non-accommodative component was 30.45 +/- 15.12 PD. Mild amblyopia was shown in 58% of these patients. The DVD or IOOA was infrequently accompanied in these patients. Stereopsis was much improved after straightening eyes. Deterioration was noticed in 14% of the patients. The longer the duration between onset and the time at straightening eyes, and the earlier the onset of deviation, the more deterioration was noticed. This study revealed that the characteristics of partially accommodative esotropia was similar to the accommodative esotropia.

A fifteen yrs old boy developed divergence paralysis following meningitic attack. The ocular examination revealed homonymous diplopia in all gazes when he fixed at further than 13 cm. He had 18 delta esotropia at distance and 7 delta esophoria at near in prism cover test. His stereopsis was excellent at near in House Fly Stereopsis Test. There wasn't much change in ocular examination in 90 days after initial examination.

PURPOSE: Duane's retraction syndrome is a congenital eye movement disorder caused by innervational disturbance. It is rare that Duane's retraction syndrome is associated with Goldenhar's syndrome which shows systemic congenital malformations. We report a case of bilateral Duane's retraction syndrome associated with Goldenhar's syndrome, which was treated with strabismus surgery and excision of epibulbar lipodermoid. METHODS: A 14-month-old boy with exotropia showed severe limitation of adduction, mild limitation of abduction, globe retraction and palpabral fissure narrowing on attempted adduction in both eyes. He also had a diffuse small epibulabar mass under the lateral conjunctiva in the left eye. The angle of exodeviation was 45PD on alternate prism cover and uncover test. He had had cleft lip, multiple skin tags on the face and preauricular appendages since birth and undergone an operation for these abnormalities at age of 4 months. Bilateral 7.5mm recession of the lateral recti and excisional biopsy of epibulbar mass of the left eye were performed. RESULTS: A case of Duane's retraction syndrome associated with Goldenhar's syndrome was found. The patient obtained orthophoria in his primary gaze after bilateral recession of lateral recti. The epibulbar mass was consistent with lipodermoid on pathologic examination.

Authur presents a 43 years old Korean housewife of pulseless disease. Because she had suffered from pulseless disease for a long time, she had many ocular complications, cataract, glaucoma and retinal detachment etc. Finally, phthisis bulbi of both eyes occured with severe left sided ocular pain and we enucleated phthisic left eye. This report describes the histopathological findings in the enucleated eye from the patient with a brief review of literature.

PURPOSE: The purpose of this study was to investigate the construct equivalence of the five general factors (subjective health, eating habits, physical activities, sedentary lifestyle, and sleeping behaviors) and to compare the latent means between male and female middle school students in Incheon, Korea. METHODS: The 2008 Korean Youth Risk Behavior Survey data was used for analysis. Multigroup confirmatory factor analysis was performed to test whether the scale has configural, metric, and scalar invariance across gender. RESULTS: Configural invariance, metric invariance, and factor invariance were satisfied for latent means analysis (LMA) between genders. Male and female students were significantly different in LMA of all factors. Male students reported better subjective health, consumed more fast food and carbonated drinks, participated in more physical activities, showed less sedentary behavior, and enjoyed better quality of sleep than female students. CONCLUSION: Health providers should consider gender differences when they develop and deliver health promotion programs aimed at adolescents.
