ABSTRACT
AlM:To observe the changes of binocular vision in V-pattern exotropia children before and after surgical correction, and the effect of training in reconstructing the binocular vision after surgical corrections.METHODS: Sixty V-pattern exotropia children were enrolled in this study and were divided into three groups according to their age:group A (4~6 years old), group B (7~9 years old), and group C (10~12 years old), 20 cases for each group. Patients received routine refraction and ophthalmic examinations. Distance and near deviation were measured by prism-covering method and synoptophore. The simultaneous perception and fusion were examined with a synoptophore, and the stereacuity was measured with stereograms ( Titmus) . The children who didn’t reconstruct binocular vision function 1wk after surgery received binocular vision training. The data were recorded before and 1 , 2, 4, and 8wk after surgery. RESULTS: Binocular vision significantly improved among the children after surgery in group A and B ( P0. 05). CONCLUSlON: V - pattern exotropia children can benefit from early surgical correction and training after surgery in reconstruct binocular vision.
ABSTRACT
AlM: To observe the therapeutic effects of improved external dacryocystorhinostomy. METHODS:Retrospective analysis on 94 patients with monocular chronic dacryocystitis in our hospital from October 2010 to December 2013 were taken the improved external dacryocystorhinostomy. The improved surgery which was based on the traditional surgery including: 1. Nasal packing after anesthesia to relieve the pain and bleeding; 2. Not cut the medial palpebral ligament; 3. Suture the upper membrane of the nasal mucosa only;4. Pipe placement;5. Skin layered hairdressing suture. The patients were follow-up 3mo-2a after operation. RESULTS: Ninety-three cases of patients cured with completely asymptomatic, no epiphora or mucopurulent secretion flow out from the lacrimal punctum, unobstructed lacrimal irrigation, the efficiency is 99%, 1 case of patient was epiphora, obstructed lacrimal irrigation, 1% was invalid. CONCLUSlON:The improved external dacryocystorhinostomy is an effective surgical method which is easy to operate with high cure rate and its long term effect is precise.
