Tablet perimetry offers a low-cost, portable glaucoma screening method. This review evaluates its effectiveness compared to traditional methods, highlighting its potential for accessible vision testing.

Area of Science:

  • Ophthalmology
  • Medical Technology

Background:

  • Glaucoma screening traditionally relies on specialized equipment like Humphrey Field Analyzers (HFA).
  • The COVID-19 pandemic accelerated the need for remote and accessible diagnostic tools.
  • Advancements in tablet technology enable sophisticated visual field testing.

Purpose of the Study:

  • To review and evaluate iPad-based perimetry applications for glaucoma detection.
  • To compare the diagnostic sensitivity and abilities of tablet perimetry with HFA.
  • To assess the correlation of tablet perimetry parameters and examination time with HFA results.

Main Methods:

  • Systematic review of studies evaluating iPad-based perimetry applications.
  • Analysis of glaucoma detection sensitivity and diagnostic accuracy.
