PURPOSE: To investigate the clinical features of Korean patients with congenital aniridia. METHODS: This retrospective study focused on 60 eyes from 31 patients who were diagnosed with congenital aniridia at Kangnam St. Mary's Hospital from 1996 to 2007. Patient age, gender, visual acuity (VA), family history, and previous ocular history were recorded. The presence of keratopathy, glaucoma, cataract, foveal hypoplasia, and other ocular or systemic anomalies were evaluated for each patient. RESULTS: The proportion of sporadic cases was 29.0%. Cataract (82.5%), glaucoma (51.6%), keratopathy (71.6%), and foveal hypoplasia (81.8%) commonly accompanied aniridia. Thirty-four (60.7%) eyes had VAs less than 20/200 and 20 eyes (35.7%) had VAs between 20/200 and 20/60. In patients without a past history of ocular surgery, the mean central corneal thickness was 643.05 +/- 37.67 microm and the mean endothelial cell count was 3,349.44 +/- 408.17 cells/mm2. Ocular surface surgeries were performed in 6 eyes. The clarity of the transplanted corneal graft vanished in 5 eyes with the progression of peripheral neovascularization and subepithelial fibrosis. The mean age of cataract surgery in 8 eyes was 29.8 +/- 5.9 years. Postoperative worsening of corneal clouding and glaucomatous damage were observed in 4 eyes. Two infants had bilateral congenital glaucoma. Two children with sporadic aniridia were identified to have Wilm's tumors. CONCLUSIONS: Congenital aniridia is a progressive congenital disorder that is commonly accompanied by complications that can lead to impaired vision. Regular, careful examinations for these accompanying complications should be performed in all patients with congenital aniridia.

OBJECTIVETo explore the model and the feasibility of newborn hearing and ocular disease simultaneous screening program and to study the birth prevalence of newborn hearing loss and newborn ocular diseases.
METHODSThe universal newborn hearing screening (UNHS) was performed using transient otoacoustic emission (TEOAE) in well baby nursery and by a two-stage TEOAE and auto auditory brainstem response (AABR) protocol in neonatal intensive care unit (NICU). The UNHS was simultaneous done with newborn ocular disease screening program. The examination technical method was following: the response to light, external inspection of the eyes and lids, pupil examination, red reflex examination, funduscope examination after pupil dilation for referral (for all newborn in NICU). The infants who were referred by two-stage hearing screening and/or had high-risk factors of hearing loss received following-up and routine audiological evaluation and personalized intervention from 6 months to 3 years of age. The cases had positive sign and (or) abnormal results of the ocular disease screening were referred for further examination by pediatric ophthalmologists.
RESULTSA total of 16 800 children born in Jinan Maternal and Child Hospital from October 1, 2002 to April 30, 2005. Of these infants, 15 398 cases (91.7%) had access to the simultaneous screening program for hearing and ocular diseases. The incidence of congenital sensorineural hearing loss (SNHL) among infants who did UNHS was 0.312% (48/15 398) in bilateral and 0.227% (35/15 398) in unilateral; Of the 4 cases of congenital SNHL complicated with newborn ocular diseases: 1 profound SNHL (bilateral), auditory neuropathy with congenital cataract (bilateral), 1 mild SNHL (bilateral) with membrana papillaris perseverance (left) and 1 mild SNHL (bilateral) with retina vein dilatation (bilateral), 1 mild SNHL (right) with persistent hyaloid artery (bilateral). In all 15 398 newborns, 15 neonates with congenital cataract were detected (22 eyes, 0.10%). Twenty seven neonates with less than 1500 g birth weight admitted to NICU, retinopathy of prematurity was detected in 3 neonates (6 eyes).
CONCLUSIONHearing loss and ocular diseases was not rare in neonatal and infancy. Newborn hearing and ocular disease simultaneous screening program was not only feasible but also effective in detecting hearing loss and (or) ocular disorders. Early intervention was important for the prevention or treatment of neonatal hearing loss and (or) ocular diseases, such as newborn hearing loss with congenital cataract, retinopathy of prematurity and so on.
