Purkinje Images II Catoptric Images II Reflections from the Eye #optometry #ophthalmology #clinical #refraction #reflexes #reflection #images In this video we have discussed and observed the Catoptric images in the eye. Purkinje images are formed due to the reflection of light rays from the optical surfaces of the eye that are cornea and lens. Total 4 images are formed by the reflections of the light. These are: 1. Purkinje Image 1 (from the anterior surface of cornea) 2. Purkinje Image 2 (from the posterior surfaceof the cornea) 3. Purkinje Image 3 (from anterior surface of the lens) 4. Purkinje Image 4 ( from the posterior surfaceof the lens) The purkinje image 1 & 2 are superimposed on each other. Thus, Image 1,2 & 3 have with movement while Purkinje image 4 gas the against movement. These images are helpful to diagnose the phackic, pseudophakic and aphakic eyes by the observing the behaviour of Purkinje Image 4.
