Clinical investigation of surgery for intermittent exotropia

Objective: To investigate the time and postoperative binocular vision of strabismus surgery for children with intermittent exotropia (X (T)). Methods: A retrospective investigation was conducted in 80 child patients with intermittent exotropia. Pre- and postoperative angles of deviation fixating at near (33cm) and distant targets (6m) were measured with the prolonged alternate cover testing. The binocular function was assessed with synoptophore. Twenty-one patients took the postoperative synoptophore exercise. Results: (1) A week after surgery, 96.2% of the 80 patients had binocular normotopia, while a year after surgery, 91.3% of the 80 patients had binocular normotopia; (2) Preoperatively, 58 patients had near stereoacuity, while postoperatively, 72 patients achieved near stereoacuity (P<0.05); (3) Preoperatively, 64 patients had Grade I for the synoptophore evaluation and postoperatively, 76 patients achieved Grade I. Meanwhile, 55 patients had Grade Ⅱpreoperatively and 72 achieved Grade Ⅱ postoperatively. For Grade Ⅲ, there were 49 patients preoperatively and 64 patients postoperatively (P<0.05); (4) Patients of 5～8 years old had a significantly better recovery rate of binocular vision than those of 9～18 years old (P<0.05); (5)Patients taking postoperative synoptophore exercise had a better binocular vision than those taking no exercise (P<0.05). Conclusions: (1) Strabismus surgery can help to preserve or restore the binocular vision for intermittent exotropia; (2) Receiving the surgery at young ages may develop better postoperative binocular vision; (3) The postoperative synoptophore exercise can help to restore the binocular vision.     

低度数儿童间歇性外斜视手术时机的选择

[目的]观察和分析低度数儿童间歇性外斜视与其手术时机的选择.[方法]观察30例低度数儿童间歇性外斜视的平均30个月自然经过,不用任何治疗.分析斜视度的变化及立体视觉的变化.[结果]发现其总体结果表明斜视度无明显恶化增大,立体视觉有所改善和提高.[结论]提出对于小于20△的儿童间歇性外斜视,其手术时机的选择,可在密切观察双眼视功能不减退时,能推迟手术数年以上.年龄较大时实施局麻手术,保证术后眼位正位的良好效果.

Comparison in effect of different metal ions,pH and reducing agent on the protease activity in human hyper mature and mature cataract

This study was undertaken to isolate and characterize the protease activity of human eye lens sample of mature and hyper mature cataract. Samples were collected just after surgery of the cataract lens and were stored at -20°C. The total protein extract was isolated from 5 samples in each case (mature and hyper mature cataract) and clear supernatant obtained after centrifugation was used as an enzyme source. The optimum pH for the proteases of mature cataract was 7.5 while the proteases of hyper mature cataract were recorded for maximum activity at pH 5.5 and 7.5. The optimum temperature for both enzyme sources was 50 °C. Effect of different metal ions such as potassium, lead, silver, zinc and borate was studied. In each case protease activity was increased. Reducing agent e.g. β mercaptoethanol also caused an increase in activity indicating the involvement of sulfhydryl groups. Protease activity was also located on agar plates.
