The Board has determined that the veteran's left forearm disorder is not distinct from his service-connected residuals of left wrist fracture and thus does not meet the criteria for separate service connection. The claim for service connection for a brain tumor (now characterized as an inferior third ventricle wall benign cystic lesion) was previously denied in 1978, but new evidence has been submitted that creates a reasonable possibility of substantiating this claim. Similarly, the claim for residuals of head trauma with headaches was also previously denied and reopened based on new evidence.

The Veteran's left wrist fracture is currently rated at 10 percent, but not higher, for the period prior to December 22, 2018. The appeal is remanded due to a claim of service connection for a lumbar spine disorder.,For the period prior to December 22, 2018, the Veteran's left wrist fracture warrants a 10 percent rating. A higher rating is denied as there is no evidence of ankylosis or other disabling conditions that would warrant a higher rating under VA regulations.,The Veteran's status post open reduction internal fixation of left proximal radius bayonetted fracture was rated at 10 percent, but not higher, for the period prior to December 22, 2018. The appeal is remanded due to a claim of service connection for a lumbar spine disorder.,The Veteran's bilateral keratoconus has been rated as noncompensable since July 24, 2020 and in excess of 10 percent thereafter. The appeal is remanded due to a claim of service connection for a lumbar spine disorder.

The Board denied service connection for a bilateral eye disability, left hand disability, left wrist fracture, and bilateral carpal tunnel syndrome due to lack of evidence linking these conditions to military service.,Service connection was also denied for the Veteran's left hand disability, left wrist fracture, and bilateral carpal tunnel syndrome as there is no credible evidence showing they were incurred or aggravated by his active duty.
