Eye Conditions C&P Exam & DBQ Guide: Evidence and Vision Testing

All Compensation and Pension (C&P) examinations for visual disorders and ocular pathology are conducted using the standardized VA Eye Conditions Disability Benefits Questionnaire. This comprehensive document captures diagnoses across the entire ocular structure, including diseases of the cornea, lens, retina, uveal tract, optic nerve, extraocular muscles, and eyelids. The public VA DBQ directory provides this document under its modern official title rather than legacy numeric form series. Reviewing the questionnaire beforehand helps claimants understand the exact clinical measurements required by rating specialists under 38 CFR 4.75 through 4.79.

The cornerstone of any VA eye examination is central visual acuity testing. Under 38 CFR 4.75, visual acuity must be measured using a standard Snellen chart or calibrated equivalent at a distance of 20 feet. Crucially, the schedule mandates that visual acuity be documented with best optical correction using corrective lenses. Uncorrected vision cannot be used to establish a compensable percentage if refractive error can be improved with spectacles or contact lenses. The examiner must record distance vision separately for each eye, note whether pinhole testing improves acuity, and record whether pathology prevents normal refraction.

When visual field defects are alleged or suspected, the examiner must perform formal perimetry. Under 38 CFR 4.76, the legal standard is a Goldmann perimeter using the III/4e stimulus, or an automated threshold perimetry test (such as Humphrey 30-2 or 24-2) converted to Goldmann equivalent. The examiner plots the visual field across eight principal meridians to determine the total field extent, which normally sums to approximately 500 degrees. The DBQ captures concentric contraction, quadrantanopsia, hemianopsia, and scotomas, providing the objective geometric data required to evaluate field loss under Diagnostic Code 6080 or 6081.

Extraocular motility testing assesses whether the eyes move together harmoniously. When double vision is present, the examiner maps the field of diplopia using a tangent screen or perimeter at a distance of 330 mm. The DBQ explicitly distinguishes occasional or intermittent double vision from constant diplopia. In accordance with 38 CFR 4.78 and DC 6090, the examiner charts the specific gaze quadrants where diplopia manifests (central 20 degrees, upward, downward, or lateral) and whether the double vision is fully correctable with prism spectacles.

For ocular conditions evaluated under the General Rating Formula for Diseases of the Eye, the DBQ requires documentation of incapacitating episodes. An incapacitating episode is defined as a period of acute symptoms requiring bed rest and treatment by a healthcare provider, or documented treatment visits for the eye condition during the previous 12 months. For secondary service connection (such as diabetic retinopathy secondary to diabetes mellitus, or retinal vascular occlusion secondary to hypertension), Association between conditions does not by itself establish secondary service connection. The evidence must support causation or aggravation in the individual claim through detailed medical nexus rationale.
