  • Congenital aniridia is a rare ocular malformation that presents with severe hypoplasia of the iris and various ocular manifestations. Most cases of congenital aniridia are known to be related to mutations in the paired box gene-6 (PAX6 ), which is an essential gene in eye development. Herein, we report a familial case of autosomal dominant congenital aniridia with four affected members in 3 consecutive generations and describe the detailed ophthalmologic findings for one of these members. As expected, mutational analysis revealed a nonsense mutation (p.Ser122*) in the PAX6 gene. Thus, our findings reiterate the importance of PAX6 mutations in congenital aniridia.

  • WAGR (Wilms tumor, aniridia, genitourinary anomalies, and mental retardation) syndrome is a rare contiguous gene deletion syndrome caused by deleting genes including WT1 and PAX6 genes in 11p13 region, which is characterized by Wilms tumor, aniridia, genitourinary abnormalities, and intellectual disability. We report the clinical and cytogenetic characteristics of one Korean patient with WAGR syndrome. The patient shows bilateral sporadic aniridia and genital anomalies at 2 months of age. A heterozygous 14.5 Mb interstitial deletion of 11p14.3p12 region was detected by array comparative genomic hybridization. At 2 years and 10 months of age, Wilms tumor is found through regularly abdominal ultrasonography and treated by chemotherapy, radiation therapy and surgery.

  • Purpose: We report a rare case of isolated traumatic aniridia in a pseudophakic eye. Case summary: A 69-year-old female came to our emergency department complaining of right eye pain and visual disturbance after trauma due to fall on the stairs. Five years earlier she had undergone an uncomplicated right sutureless phacoemulsification cataract extraction through a 2.2 mm temporal clear corneal incision, followed by insertion of a folding intracapsular intraocular lens. Total iris expulsion occurred through the cataract incision without extension of the wound or disruption of the posterior capsule or intraocular lens. Conclusions: We report a rare case of isolated traumatic aniridia in a pseudophakic eye, which has not been reported in the Republic of Korea.

Wilms' tumor, aniridia, genitourinary anomalies, and mental retardation (WAGR) syndrome: Successful treatment of the first case with bilateral Wilms' tumors in Korea (윌름즈 종양, 무홍체증, 비뇨생식기계 기형, 정신지체 (WAGR) 증후군 : 양측성 윌름즈 종양을 성공적으로 치료한 국내 첫 증례 보고)

  • Wilms' tumor, aniridia, genitourinary anomalies, and mental retardation (WAGR) syndrome is caused by deletion of chromosome 11p13, including the Wilms' tumor (WT1) and aniridia gene (PAX6) loci. Here, we report the first case of WAGR syndrome in Korea; the patient was a 2-year-old girl with bilateral aniridia from birth who presented with abdominal distention and mental retardation. Cytogenetically, she had deletion of chromosome 11p11.2-13. Bilateral Wilms' tumors were successfully treated by chemotherapy and surgery. She has been tumor-free for 19 months off chemotherapy with preserved renal function.

  • We operated on 199 patients of VSD from 1976 to April l986. Among them, patients of VSD whose medical records were available were analyzed clinically. Operation on patients of VSD occupied 23.9% of total open heart surgery [832 cases] during those days. Of the 164 patients, 93 patients were male [56.7%]. 71 patients were female [43.3%]. Their age ranged from 6 months to 28 years and the mean age was 9.5 year and 82.2% of the patients were between 2 and 15 year of age. Of the patients, body weight below 10Kg were 19 cases. The most common complaints were frequent URI and DOE. On Kirklin`s anatomical classification, type II defect was most common [60.1%], type I [38.4%], combined type I+II, type III, combined type II+Ill and combined type II+IV in orders. Associated anomaly was found in 66 patients [42.5%>]. Pulmonary stenosis was most commonly associated cardiac anomaly [8.4%] and aortic insufficiency [7.1%], ASD, Lt. SVC and PDA in orders. There were extracardiac anomalies such as polydactyly, cleft palate, hypospadia and congenital aniridia, etc. Relationship between ventricular hypertrophy and defect size and cardiac cath. data was analyzed. The overall mortality was 7.0% [14 cases] and complication rate was 22.5% [35 cases].
