目的 :探讨影响原发性先天性青光眼术后视力的原因及预防措施。方法 :追踪检查 5 1只接受手术治疗后 10年以上的原发性先天性青光眼的眼压、视力、角膜及杯盘比值等的变化情况。结果 :手术不成功的 12只眼视力全部在 0 .0 5以下。手术成功的 39只眼视力在 0 .1至 0 .8以上 ,7只单眼发病者视力都在 0 .2以下 ;角膜直径大于 13mm的 2 7只眼中 2 1只眼有 Haab线存在 ;杯盘比值大于 0 .2以上者 12只眼。结论 :手术不成功 ,长期高眼压是造成原发性先天性青光眼盲目的根本原因 ;手术成功后视力的好坏则取决于术前视神经受损害 ,角膜受损害的程度和术后弱视发生的情况 Objective: To investigate the causes and preventive measures of visual acuity after primary congenital glaucoma surgery. Methods: The changes of intraocular pressure, visual acuity, corneal and cup ratio of 51 primary congenital glaucoma patients who underwent surgery for more than 10 years were followed up. Results: All 12 eyes with unsuccessful surgery had visual acuity of less than 0.05. The successful surgeries of 39 eyes had a visual acuity between 0. 1 and 0. 8, with visual acuity of 0.2 or less in 7 patients with monocular eyelid; Haab lines in 2 of 27 eyes with corneal diameter greater than 13 mm; The ratio is greater than 0.2 above 12 eyes. CONCLUSION: Long-term intraocular hypertension is the primary cause of blindness in primary congenital glaucoma after surgery. The success or failure of visual acuity depends on the preoperative damage of the optic nerve, the degree of corneal damage, and the postoperative amblyopia Happening
