The Auto Perimeter GlauField Lite SWAP is a professional computerized ophthalmic diagnostic instrument designed for automated visual field testing, glaucoma assessment and neuro-ophthalmic examinations. Manufactured by Appasamy Associates, the system combines conventional automated static perimetry with Short-Wavelength Automated Perimetry (SWAP) to provide additional visual field testing capabilities.
Also known as the Appasamy GlauField Lite SWAP, AP901 CTS GlauField Lite SWAP, SWAP Automated Perimeter, Blue-on-Yellow Visual Field Analyzer, Glaucoma Perimeter with Printer or Computerized Ophthalmic Visual Field Testing System, the equipment is suitable for eye hospitals, glaucoma clinics, ophthalmology departments and specialist diagnostic centres.
Visual field testing is an important part of professional eye examination because it assesses how effectively a patient detects visual stimuli at different locations within the visual field.
Changes in visual field sensitivity can be associated with glaucoma, optic nerve abnormalities, retinal disease and certain neurological conditions.
The GlauField Lite SWAP uses an automated examination system to present controlled visual stimuli while recording patient responses.
Its distinguishing feature is SWAP technology, a specialized form of automated perimetry that traditionally uses blue stimuli against a yellow background.
This examination technique emphasizes short-wavelength-sensitive visual mechanisms and provides additional information about visual field function.
SWAP may reveal certain functional abnormalities that are less apparent during conventional white-on-white perimetry in selected patients. However, it should not be considered universally more accurate or more sensitive in every clinical situation.
The GlauField Lite SWAP also incorporates computerized analysis functions, including the Glaucoma Hemifield Test (GHT), Visual Field Index (VFI), Guided Progression Analysis (GPA) and gaze-tracking functionality.
These features support interpretation of visual field results, assessment of examination reliability and comparison of repeated tests.
The system provides examination strategies for general visual field screening, central field assessment, glaucoma evaluation, macular examinations and selected neurological screening applications.
Its Field Explorer analysis software offers graphical displays and clinical reporting tools for reviewing examination results.
The Auto Perimeter GlauField Lite SWAP with Printer and Motorized Table package listed by Maesio Pharmaceuticals provides an examination workstation with printing capability and an electrically adjustable table.
The motorized table helps accommodate patients of different heights and supports suitable positioning during visual field testing.
The included printer allows examination findings to be produced as physical reports for patient records and clinical review.

The system supports conventional computerized visual field examinations using its available testing strategies.
Provides measurements that help clinicians identify visual field patterns that may be associated with glaucoma.
GHT compares relevant regions of the visual field and provides a summary interpretation.
VFI gives a global index summarizing visual field function.
GPA supports comparison of serial examination results to identify statistically significant changes.
Selected examination patterns can assist assessment of visual field abnormalities requiring neurological investigation.
Gaze tracking and other fixation-monitoring functions help clinicians evaluate examination reliability.
Field Explorer software allows results to be reviewed, stored and printed.
The GlauField Lite SWAP uses controlled visual stimuli presented within a calibrated examination bowl.
The patient is positioned at the instrument with the head appropriately supported.
The patient is instructed to maintain fixation on a designated target.
During testing, the system presents light stimuli at selected visual field locations.
The patient presses the response button whenever a stimulus is detected.
The system records these responses and calculates visual sensitivity measurements according to the selected test strategy.
During SWAP examinations, short-wavelength stimuli are presented against a specially configured background.
The resulting measurements provide information about short-wavelength-sensitive visual function.

The GlauField Lite SWAP provides visual field measurements and does not independently diagnose glaucoma, neurological disorders or retinal disease.
Visual field abnormalities require interpretation alongside the patient's clinical history, optic nerve assessment, intraocular pressure measurement and other relevant investigations.
SWAP measurements may be affected by ocular media opacity, particularly lens changes that reduce short-wavelength light transmission.
Age, fatigue, attention, fixation stability and learning effects can influence testing reliability.
Results from SWAP and standard white-on-white perimetry should not be treated as directly interchangeable.
Progression analysis requires suitable repeat examinations, consistent testing methods and appropriate interpretation of variability.
A normal visual field result does not exclude early eye disease.
