Abstract

The effect of peribulbar anaesthesia on optic nerve function in 20 patients, before and after cataract surgery, was measured. All the patients had decreased visual acuity. Five (25%) had no perception of light. Seventeen (85%) developed a relative afferent pupil defect (RAPD). No patients saw the operating instruments. Seven (35%) had improved visual acuity immediately postoperatively. Patients should be warned that they may lose vision completely on being given a peribulbar anaesthetic; however their vision will improve, but not necessarily immediately, postoperatively. Examination for an RAPD is a good method of providing reassurance that the operating instruments will not be seen.

摘要

测量了20例患者在白内障手术前后球周麻醉对视神经功能的影响。所有患者视力均下降。5例(25%)无光感。17例(85%)出现相对传入性瞳孔障碍(RAPD)。没有患者看到手术器械。7例(35%)术后视力立即改善。应告知患者,给予球周麻醉后他们可能会完全失明;然而术后视力会改善,但不一定是立即改善。检查有无RAPD是一种很好的方法,可让患者放心不会看到手术器械。
