[The visual field of patients with pseudophakia using kinetic and automated perimetry]

One of the major benefits of pseudophakia is to maintain a good visual field. Visual field was therefore studied in 40 pseudophakic eyes using: 1. kinetic perimetry according to Goldmann using 3 tests: I1, I2, I4; 2. Automated perimetry. Insertion of a posterior chamber intraocular lens was performed in 85% of cases whereas the remaining 15% received an anterior chamber intraocular lens. Visual acuity was > 5/10 P2-P4 in all patients. The results showed a 15% reduction in the visual field compared to normal values. This reduction was concentric and harmonious but was more marked in internal isopters. This reduction was less marked with posterior chamber intraocular lenses. On the other hand, automated perimetry showed that global retinal sensitivity was decreased in pseudophakia, and this deficiency was more pronounced in the periphery.
