  • Title: [Influence of cataract on automated perimetry].
    Author: Yao K, Flammer J.
    Journal: Zhonghua Yan Ke Za Zhi; 1993 Jan; 29(1):13-5. PubMed ID: 8334901.
    Abstract:
    58 eyes of 58 patients underwent cataract surgery with IOL implantation. The density of cataract was quantified by the Opacity Lensmeter 701 before operation and the visual field by program G1 of Octopus 201 before and after operation. The visual fields showed that there was significant difference in the mean defect (MD) before and after operation, but not in the corrected loss variance (CLV), indicating that cataract only caused diffuse visual field damage. This was also confirmed by the parallel shift of the mean cumulative defect curve after surgery. The preoperative lens opacity reading and the visual acuity were correlated with the difference between the pre- and post-operative MD, showing that measurement of OLM 701 and visual acuity permitted assessment of the influence of cataract on the visual field.
