The Veteran's left eye disability, which had been rated at 30 percent since June 4, 2006, was reduced to 10 percent effective April 22, 2015. The Board found that the reduction was not proper as there was no evidence of actual improvement in the ability to function under ordinary conditions of life and work.

The Board granted an initial 40 percent disability rating for bilateral eye disabilities but denied ratings for abdominal scars, hypertension, and remanded claims related to thrombosis and arthritis.

The Board granted an effective date of February 29, 2016, for the award of service connection for bladder incontinence and granted service connection for bowel incontinence as secondary to the Veteran's service-connected lumbosacral spine disability.

The Board remands the claim for a left eye disability, to include refractive amblyopia from congenital astigmatism, left eye nuclear cataracts, and left eye corneal scar, for further development of evidence regarding the nature and etiology of the Veteran's left eye corneal scar.

The Board remands the issue of entitlement to a rating in excess of 30 percent for right eye disability resulting in diplopia, including consideration of a separate rating for headaches, due to an insufficient VA medical opinion on whether the service-connected right eye disability aggravated the nonservice-connected headaches.
