Clinical Experience of Canaliculaoplasty Using Mini-Monoka

Surgical effects were evaluated in 37 cases of mono-canalicular laceration following canaliculoplasty using Mini-Monoka from April, 1993 through SEptember, 1997 in the Department of Ophthalomology, Yeungnam University, College of Medicine. Lower canalicular laceration was included in 33 cases and upper canalicular laceration was found in 4 cases. Distance from the punctum to the lacerated canaliculus was noted to be 1 to 9mm(mean 4.6mm) and age ranged from 3 to 57 years(mean29.3 years). Thirty-four patients were men and three were women. Punctal portion of Mini-Monoka was fixated at the punctum with 6-0 black silk suture. End to end anastomosis was performed with 9-0 Ethylone(spatula needle) or 6-0 Vicryl(round needle). Steroid and antibiotics eye drops were used for 6 months after surgery. Mini-Monoka was removed 4 months postoperatively. After the follow-up period of 6-49 months(mean 11.3 months), 36 cases became recanalized well but 1 case showed obstruction because the laceration site was distant, 9mm from the punctum. Postoperative complications included loss of tube(3 cases), granuloma of the punctum(3 cases) and corneal abrasion(2 cases). Canaliculoplasty using Mini-Monoka is a procedure of choice for repair of mono-canalicular laceration with prevention of loss of the tube by punctal fixation suture without damage of the intact another canaliculi and the inferior meatus.

Ocular Fundus Findings in Children with Strabismus

The authors have examined 980 children with strabismus who were 6 years of age or under at the Eye Clinic of Yeungnam University Hospital. This study was conducted during the 4-year period between January 1990 and December 1994. The main objective of this study was to determine the incidence and clinical characteristics of fundus abnormality in children with strabismus. The total number of subjects in this study are 980 cases. Sixty subjects(6.1%) are found to have optic disc, chorioretinal and vitreous anomalies. Among them, 26 cases(43%) are diagnosed as having optic nervehypoplasia, in 7 cases (12%) coloboma, in 4 cases(7%) morning glory syndrome, in another 4 cases persistent hyperplastic primary vitreous, and in 3 cases retinoblastoma. In our study, 6.1% of the patients with strabismus are found to have disorders in optic disc and vitreoretina. These finding suggests that infants and young children with strabismus should have been examined to detect other related disorders of the eye.
