目的 探讨视野在原发性先天性青光眼疗效观察中的价值。方法 对17例28眼先天性青光眼的视野资料进行回顾性分析,并就视力、眼压、杯盘比值、手术次数、手术年龄等因素与视野的关系进行探讨。结果 初次检查视野的年龄4～16岁,平均11.52±3.47岁,视野检查距手术的时间1～14年,平均6.7年。矫正视力≥0.4者占78.57％,其中>0.8者占46.43％。22眼具有青光眼性视野缺损,占78.57％,其中旁中心暗点5眼,鼻侧阶梯9眼。弓形缺损6眼,管视和/或颞岛7眼。早、中、晚三期视野损害所占比例分别为:32.14％、21.43％、25.00％。8例13眼有视野随访,随访时间3～13年,平均6.6年,6眼有视野进展。手术次数≥2次组的视野损害较≤1次手术组重(P<0.05)。杯盘比值≥0.6组的视野损害明显重于C/D<0.6组(P<0.05)。结论 视野是评价先天性青光眼疗效的一个重要指标,先天性青光眼患者经训练后能够完成视野检查。
Objective To explore the value of visual field in the treatment of primary congenital glaucoma. Methods The visual field data of 17 cases with congenital glaucoma of 28 eyes were analyzed retrospectively. The relationship between visual field, intraocular pressure, ratio of cup and disk, the number of operation and the age of operation were analyzed. Results The initial inspection field of vision of 4 to 16 years old, with an average of 11.52 ± 3.47 years old, visual field examination from the operation of 1 to 14 years, an average of 6.7 years. Correction of visual acuity ≥ 0.4 accounted for 78.57%, of which> 0.8 accounted for 46.43%. Twenty-two eyes had glaucomatous visual field defects, accounting for 78.57%, of which 5 were dark circles in the center and 9 were nasal stairs. 6 cases of arcuate defect, 7 cases of ductal and / or temporal island. Early, middle and late three visual field damage accounted for the proportion of: 32.14%, 21.43%, 25.00%. Eight patients (13 eyes) had visual field follow-up of 3-13 years (average 6.6 years), and 6 eyes had visual field progression. The visual field damage of group ≥2 was less than that of group ≤1 (P <0.05). The visual field damage in the cup-plate ratio≥0.6 group was significantly higher than that in the C / D <0.6 group (P <0.05). Conclusion The visual field is an important index to evaluate the efficacy of congenital glaucoma. The patients with congenital glaucoma can complete visual field examination after training.
