MED 4 (02/10/2018)
A Acuity: Visual Acuity should be recorded at the lowest line where an individual scores 100% correct. Whole numbers only. Visual requirements must
be met without the aid of a telescopic lens. Some drivers may be granted waivers from these vision requirements.
B. CDL Waiver: Holders of or applicants for a Commercial Driver's License (CDL) or Commercial Learner's Permit (CLP), who are unable to meet Virginia
minimum vision requirements may apply to DMV's Medical Review Services for a disability waiver to qualify for an intrastate only CDL or CLP, provided
they meet the Federal Motor Carrier Safety Administration Regulations' minimum vision requirements. Color perception is required. Please have your
eye care practitioner submit a graphic visual field analysis to 120 degrees in each eye.
C. Visual Field (VF): Individuals who have a high-risk condition that can reduce the usable field of vision should have a baseline Visual Field Analysis
(VFA) performed. Conditions that are progressive, such as retinitis pigmentosa and glaucoma, will be reviewed by DMV annually. Repeat VF testing will
be requested when changes are reported in the visual field or at a minimum of every 3 years.
High Risk Ophthalmic Conditions Requiring a Visual Field Analysis:
• Hemianopia (complete) and Quadrantanopia (complete). Partial hemianopic and quadrantanopic defects may be considered safe for driving if the
individual demonstrates an adequate field of vision in the unaffected side and the affected side retains or regains 30 degrees temporally with 15
degrees above and below the horizontal line for the full 30 degrees.
• Bitemporal hemianopia may drive if combined nasal measurement meets the Virginia standard for horizontal vision of 40 degrees to one side and
30 degrees to the other side for a minimum of 70 degrees total as demonstrated by VFA.
• Other visual field loss from strokes, tumors or compressive disorders
• Glaucoma - Moderate to Severe stage
• Ischemic, traumatic, compressive, toxic , hereditary (Lebers) or malnutrition related optic neuropathy
• Optic neuritis
• Optic nerve head edema - papilledema
• Optic atrophy
• Proliferative diabetic retinopathy status post pan retinal photocoagulation
• Retinitis pigmentosa
• Retinal ischemia due to artery or vein occlusions and uveitis etiologies
• Retinal detachment
• Retinal laser procedures
• History of retinopathy of prematurity or radiation retinopathy
Measuring Visual Fields for DMV Vision Reports:
• To determine visual field loss, DMV requires the results of a visual field test that measures the central 24 to 30 degrees of the visual field; that is,
the area measuring 24 to 30 degrees from the point of fixation. Acceptable tests include the Humphrey Field Analyzer (HFA) 30-2, HFA 24-2,
Octopus 32 or equivalent threshold perimetry test. In addition, testing needs to be completed to 120 degrees (60 degrees from the point of
fixation) i.e. HVF 60-4 or equivalent.
• Screening tests: DMV will not accept the results of visual field screening tests, such as confrontation tests, tangent screen tests, or automated
static screening tests, to determine if the visual field meets DMV requirements when an individual has a condition that places them at high risk for
visual field loss.
• Use of corrective lenses: Eyeglasses should not be worn during visual field testing because they limit the field of vision. Individuals may wear
contact lenses to correct visual acuity during the visual field test to obtain the most accurate visual field measurements.
• Scotoma: A scotoma is a field defect or non-seeing area (also referred to as a “blind spot”) in the visual field surrounded by a normal field or
seeing area. When measuring the visual field, subtract the length of any scotoma, other than the normal blind spot, from the overall length of any
diameter on which it falls.
