Diagnostic Code 6091 · 38 CFR §4.79
Symblepharon is an adhesion between the conjunctiva of the eyelid and the conjunctiva of the eyeball. It occurs when scar tissue forms between these surfaces, typically after chemical burns, thermal burns, radiation exposure, or severe infections. For veterans, this condition most commonly results from chemical or thermal burns sustained during service. Symblepharon can restrict eye movement, cause chronic dryness, and impair vision depending on its location and extent.
| Rating | Criteria |
|---|---|
| 10% | Symblepharon causing limited eye movement or chronic irritation but not significantly affecting visual acuity. |
| 20% | Moderate symblepharon restricting eye movement and causing visual impairment through incomplete lid closure or corneal involvement. |
| 30% | Severe symblepharon with significant restriction of eye movement, corneal involvement affecting vision, and chronic surface disease. |
| 0% | Minimal adhesion with no functional limitation or visual impact. |
Ophthalmology examination documenting the location and extent of the adhesion, photographs showing the symblepharon, documentation of the causative injury (chemical burn, thermal burn), records of eye movement limitation, and visual acuity testing if the cornea is involved.
Surgery can release the adhesion, but recurrence is common, especially after severe burns. Even if surgery is attempted, the scar tissue may reform. Document any surgical attempts and recurrences to support ongoing disability.
Yes. Chemical burns during service are a direct cause of symblepharon. Document the exposure event, any immediate treatment received, and the subsequent development of the adhesion.
