  • Title: Cataract Image Analysis System.
    Author: Cotlier E.
    Journal: Eye (Lond); 1999 Jun; 13 ( Pt 3b)():457-63. PubMed ID: 10627825.
    Abstract:
    A system for sequential colour video capture and analysis of lens opacities is described. A sensitive RGB (Red-Green-Blue) camera is coupled to a 486 DX2/66 IBM-compatible computer to obtain high-resolution images of cataracts. Vacuoles, retro-dots, suture opacities, wedge opacities, cortical and posterior subcapsular opacities and nuclear sclerosis can be digitised and subjected to various analysis systems and colour prints obtained. The size and number of vacuoles and opacities can be determined by selecting areas of interest, and line tracings of whole lens, isolated opacities or nuclear sclerosis can be separated by analysis into 16.8 million plus colour gradients. The Cataract Image Analysis System represents a precise and new digitised procedure for cataract documentation and may be of value in determining cataract progression and evaluation of medical therapy.
