摘要
目的观察玻璃体切除术中黄斑前玻璃体残留患眼的临床表现。方法曲安奈德（Triamcinoloneacetonide）辅助下行玻璃体切除术484例（509只眼），切除前段及中央部玻璃体，注入曲安奈德混悬液，进行玻璃体染色，术中观察玻璃体是否后脱离及黄斑前有无玻璃体残留，分析玻璃体残留与年龄、原发病、发病时间等因素的关系。结果509只眼中，黄斑前玻璃体残留者34只眼，残留率为6．68％。0—20岁组残留率为18．64％；21～40岁组残留率为7．88％；41～60岁组残留率为4．17％；60～76岁组残留率为2．15％。二分类变量logistic回归分析，OR=0．445，95％可信区间为0．298—0．666。孔源性视网膜脱离组残留率为11．61％；眼外伤组残留率为10．52％；将孔源性视网膜脱离与眼外伤组合为一组，其余原发病合另一组，比较采用卡方检验，χ2=16．104，P〈0．001，两组间残留率差异有统计学意义。孔源性视网膜脱离组和眼外伤组出现残留者的平均发生时间分别为（10．39±6．02）d和（10．90±4．70）d。结论玻璃体切除术中黄斑前玻璃体残留更容易在孔源性视网膜脱离、眼外伤、年龄偏小及发病早期的患者中出现。
Objective To analyse the clinical features of patients who had the pre-macular residual vitreous in pars plana vitrectomy （PPV）. Methods Triamcinolone acetonide-assisted pars plana vitrectomy was performed on 509 eyes of 484 cases. The front and central vitreous body was removed, and the Triamci- nolone aeetonid （TA） was injected to check if there was posterior vitreous detachment. The pre-macular re- sidual vitreous was observed during the operation. The relationship between residual vitreous and age, prima- ry disease and the duration of the disease was analyzed. Results Of the 509 eyes, the pre-macular residual vitreous occurred in 34 eyes and the residual rate was 6.68 %. The rates of the pre-macular residual vitreous in different ages were 18.64% in 0 -20 years group, 7.88% in 21 -40 years group, 4.17% in 41 -60 years group, 2.15% in 60 - 76 years group. OR value of Logistic regression analysis of binary classification variables was 0. 445, and 95% confidence interval was 0. 298-0. 666. The residual rate in rhegmatogenous retinal detachment （RRD） group was 11.61%. The residual rate in ocular trauma group was 10.52%. The difference in residual rate of RRD and ocular trauma cases was significantly highter than the other cases （χ2 = 16. 104 ,P 〈0.001 ）. The average occurrence time of RRD group and ocular trauma group were （ 10.39 ± 6.02） days and （ 10.90 ± 4.70） days respectively. Conclusion The pre-macular residual vitreous is easi- er to occur in patients who have RRD, ocular trauma, younger age, and at the early stages of diseases.
