Visual Field Defect Interpreter
Select the pattern of visual field loss and get the probable anatomical lesion location along the visual pathway with a brief explanation.
Use the Visual Field Defect Interpreter
Step 1 — Which eyes are affected?
Choose the laterality of the visual field loss.
Step 2 — Select the defect pattern
Pick the closest description of the field loss.
Select a defect pattern on the left to see the localization.

Summary
The Visual Field Defect Interpreter maps described visual field loss patterns to probable anatomical lesion sites along the visual pathway. By selecting the laterality and character of the defect — monocular, bitemporal, or homonymous — clinicians and students can quickly identify whether the lesion lies at the retina, optic nerve, chiasm, optic tract, lateral geniculate nucleus, optic radiations (parietal or temporal), or occipital cortex. Each result includes a concise clinical explanation and key distinguishing features.
How it works
- Select the affected eye(s): one eye (monocular), both eyes with bitemporal loss, or both eyes with homonymous (same-side) loss.
- Choose the defect pattern that best matches the visual field loss description.
- Review the probable anatomical location and the clinical explanation.
- Use the pathway diagram to visualize where along the visual pathway the lesion lies.
- Cross-reference with clinical signs to confirm localization.
Use cases
- Ophthalmology residents learning visual pathway anatomy.
- Clinicians correlating perimetry results with imaging findings.
- Medical students studying neuro-ophthalmology for exams.
- Neurologists localizing lesions from bedside confrontation testing.
- Optometrists reviewing Humphrey field analyzer reports.
- Educators creating teaching cases around visual field defects.
