This study introduces a novel smartphone-based method for early cataract detection using luminance features. The approach achieves high accuracy, offering an affordable and accessible tool for remote eye health monitoring.

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Computer Science

Background:

  • Cataract is the leading cause of blindness in the U.S., necessitating early detection for effective management.
  • Current diagnostic tools can be expensive and inaccessible, particularly in remote or underserved areas.

Purpose of the Study:

  • To develop an efficient and accessible smartphone-based method for early cataract detection.
  • To leverage luminance features for accurate identification of cataractous changes in the eye lens.

Main Methods:

  • Eye images were captured using smartphones, with the lens region extracted and preprocessed.
  • A novel luminance transformation algorithm was applied to extract image features.
  • Support Vector Machines (SVM) were employed for the classification of cataract eyes.
Keywords:
