遗传性晶体脱位术后弱视治疗

Amblyopia Therapy of Postopeartion in Patients with Ectopia lentis

报告12例23眼遗传性晶体异位的弱视病人，其半脱位晶体因影响视力矫正而被手术摘除。手术年龄4～32岁，术后所有术眼早期视力虽有不同程度的提高，但因弱视而限制在0．3－0．5，术前ERG检查表明视网膜功能正常．术后通过进行简单的视力训练，远期矫正视力有了显著的提高，为0．5－1．0，年龄大于8岁的患者接受训练后，同样获得明显的视力改善。表明屈光不正性弱视的治疗在年长的儿童甚至成人也可能成功．

Visual rehabilitation in aphakic patients has tradi-tionally yieded poor results. Advances in surgical tech-nique and instrumentation, plus the advent of newer methods of optical correction and orthoptic therapy,have improved the outlood for older children. We re-ported here 12 amblyopia patients (23 eyes )with ectopia lentis,whose subluxated lenses were removed by surg-ery all because of optical reason,and their ages at the surgrey ranged from 4 to 32 yrs. The initial corrected vision of postoperation improved in all 23 eyes (0- 3- 0.5 ), and was limited only by amblyopia. Elec-troretinography (ERG)showed normal retinal function in most of patients. After completing simple vision therapy at - home or in - office, their final corrected vision was significant improvement in all 23 amblyopic eyes,ranging from 0. 5 - 1.0 during a follow- up peri-od ranging from 6 to 65 months (medium45 months).Patients older than 8 yesrs who complied with treat-ment showed a marked improvement in visual acuity.This study indicated that treatment of refractive am-blyopia may be successful even with some older chil-dren and adults.
