Effect of Induced Refractive Error and Nuclear Sclerotic Cataracts on Ishihara Colour Plate Testing
Journal Title: International Journal of Anesthesiology & Research (IJAR) - Year 2014, Vol 2, Issue 2
Abstract
Objective: To determine the effect of induced refractive blur and nuclear sclerotic (NS) cataracts on Ishihara colour plate (ICP) scores. Design: Prospective evaluation of a diagnostic test Participants: Patients who presented to Hotel Dieu Hospital Eye clinic between January and March 2010 with either a lone diagnosis of nuclear sclerotic cataracts, or with no identified ocular disease with complete examination. Methods: Patients were divided into two groups: those having no identified ocular disease on examination, and those with a lone diagnosis of NS cataracts. The first group was refractively blurred with +3D, +6D, +9D and +12D lenses. Best corrected visual acuity (BCVA) at near and ICP scores was obtained from both groups.
