Optic Neuropathy — VA Disability Rating Criteria (DC 6026)

Diagnostic Code 6026 · 38 CFR §4.79

What Is It?

DC 6026 appears in 38 CFR 4.79 as a bare line — "6026 Optic neuropathy" — with an empty rating column and no criteria of its own. That is deliberate, and it does not mean the code has no standard. Section 4.79 opens with an instruction that governs every code beneath it: unless otherwise directed, evaluate diseases of the eye under the General Rating Formula for Diseases of the Eye. When VA rewrote this part of the schedule effective 13 May 2018 it deleted the per-code evaluation sentence from DC 6026, explaining in the rule that the language was redundant of that general instruction and moving the instruction to sit immediately beneath the section heading. So a code with no visible criteria takes the General Rating Formula. The formula itself offers two routes and pays whichever is higher. Its opening line reads "Evaluate on the basis of either visual impairment due to the particular condition or on incapacitating episodes, whichever results in a higher evaluation." The incapacitating-episode route is a count of treatment visits over the past twelve months, laid out in the table below. The visual-impairment route sends the claim to 38 CFR 4.75 through 4.78 and to the visual codes at the end of 4.79 — acuity under DCs 6061 through 6066, visual field defects under 6080, scotoma under 6081, and diplopia under 6090 — where evaluations run to 100 percent. Be precise about what an incapacitating episode means here, because the phrase is used in several body systems with different definitions. Note (1) to this formula defines it as "an eye condition severe enough to require a clinic visit to a provider specifically for treatment purposes." There is no bed-rest requirement and no threshold measured in weeks — those belong to the intervertebral disc formula in 38 CFR 4.71a, not to the eye. Note (2) gives examples of qualifying treatment: systemic immunosuppressants or biologic agents, intravitreal or periocular injections, laser treatments, or other surgical interventions. Optic neuropathy is damage to the optic nerve carrying signal from retina to brain. In veterans the recurring causes are traumatic — direct orbital injury, blast, and the shearing forces of traumatic brain injury — along with ischaemic, toxic, nutritional and demyelinating mechanisms. Its signature is a mismatch between how the eye looks and how it performs: acuity can be preserved while colour vision desaturates and the visual field develops defects, which is why formal perimetry and colour testing decide these claims more often than an acuity chart does. Note also 38 CFR 4.75(d), which caps the visual-impairment evaluation for one eye at 30 percent unless the eye has been anatomically lost.

Rating Criteria

Evidence Needed

Build the visual-impairment side and the treatment-visit side in parallel, because the formula pays the higher of the two. For visual impairment: formal perimetry under 38 CFR 4.77(a) using Goldmann kinetic or automated Humphrey or Octopus testing, best-corrected distance acuity, formal colour vision testing, and optical coherence tomography of the retinal nerve fibre layer showing thinning. Visual evoked potentials give objective evidence of conduction delay when subjective testing is disputed. MRI of the orbits and brain establishes the lesion and helps separate traumatic from demyelinating causes. For the episode side, an itemised list of treatment visits with dates over the last twelve months is what the table is actually scored against — a summary letter saying you are treated regularly does not produce a count. Add the nexus opinion tying the neuropathy to service or to a service-connected condition such as TBI.

C&P Exam Tips

Ask for all three components of visual impairment to be measured — acuity, formal visual fields, and muscle function — because 38 CFR 4.75(a) defines visual impairment as all three and optic neuropathy characteristically spares the first while damaging the second. Request colour vision testing explicitly; desaturation is often the earliest and most disabling deficit and it is routinely omitted. Ask the examiner to document optic disc appearance and any relative afferent pupillary defect, which is objective evidence a claimant cannot influence. Bring the dated list of treatment visits and hand it over rather than describing your treatment in general terms. If the neuropathy followed a head injury, make sure the examiner has the TBI records in front of them, since the causal link is what a nexus opinion is written from.

How to File

File under DC 6026, and where the neuropathy followed a service-connected traumatic brain injury or toxic exposure, file it as secondary to that condition. Submit both bases at once: the perimetry and acuity records for the visual-impairment route, and the dated treatment-visit list for the incapacitating-episode route. The formula requires VA to pay the higher, and a decision that addresses only one has not made the comparison the schedule directs. If the visual field is the impaired component, say so in the claim so DC 6080 is examined on its own terms.

Common Mistakes

Importing the wrong definition of an incapacitating episode is the mistake this code invites. Veterans and representatives frequently argue weeks of prescribed bed rest, which is the intervertebral disc standard from 38 CFR 4.71a; the eye formula counts clinic visits for treatment and says nothing about bed rest. A second error is accepting an evaluation built on visual acuity alone when the deficit is in the field or in colour vision. A third is failing to connect the neuropathy to a service-connected TBI, so a clearly related condition is adjudicated on direct service connection and denied. Veterans also under-document colour vision loss, which is genuinely disabling for anyone whose work depends on colour discrimination and is invisible on every test except the one nobody ordered.

Frequently Asked Questions

Why does 38 CFR 4.79 show no criteria beside DC 6026?

Because the criteria are supplied by the section's opening instruction rather than repeated at each code. Section 4.79 directs that, unless otherwise directed, diseases of the eye are evaluated under the General Rating Formula for Diseases of the Eye. VA removed the duplicate sentence from DC 6026 in the rule effective 13 May 2018 precisely because it repeated that instruction. A blank rating column here means the formula applies, not that the code is unratable.

What counts as an incapacitating episode for an eye condition?

Note (1) to the formula defines it as an eye condition severe enough to require a clinic visit to a provider specifically for treatment purposes. Note (2) gives examples: systemic immunosuppressants or biologic agents, intravitreal or periocular injections, laser treatments, or other surgical interventions. There is no bed-rest element and no duration in weeks — that standard belongs to a different body system.

Can I be rated above 60 percent for optic neuropathy?

Yes, but through the visual-impairment route rather than the episode count. The formula pays whichever basis is higher, and the visual codes at the end of 38 CFR 4.79 run to 100 percent. Note the limit in 38 CFR 4.75(d): the visual-impairment evaluation for one eye cannot exceed 30 percent unless the eye has been anatomically lost.

Can traumatic brain injury cause optic neuropathy?

Yes. Traumatic optic neuropathy is a recognised consequence of head injury, arising from direct compression, shearing at the optic canal, or swelling. Where the TBI is service-connected, the neuropathy is claimed as secondary to it. What the claim needs is a neurology or ophthalmology opinion naming the mechanism, not merely a record that both conditions exist.

My acuity is normal but my colour vision is not. Is that ratable?

Colour vision is not itself one of the three components of visual impairment under 38 CFR 4.75(a), which are acuity, visual field and muscle function. It matters as evidence: desaturation is often the first objective sign of optic nerve damage and it supports the diagnosis and the severity picture. Get it tested, and pair it with perimetry, which is where a nerve deficit does convert into a rating.

Does the rating change if the neuropathy stabilises?

Traumatic optic neuropathy typically stabilises after the injury and rarely recovers, while ischaemic and demyelinating forms can progress or relapse. Either way the evaluation follows the current impairment, so a stable deficit keeps its rating and a progressive one supports an increase. Serial perimetry over years is the record that makes progression provable rather than asserted.
