The Board denied service connection for eye disability, including bilateral exotropia, macular degeneration, cataracts, dry eye syndrome, and pinguecula, as the evidence did not support a finding that these conditions were caused by or related to the Veteran's military service.

The Board granted service connection for eye conditions, an acquired psychiatric disorder, and obstructive sleep apnea as secondary to the Veteran's service-connected diabetes mellitus type II with erectile dysfunction and left eye retinopathy. However, it denied increased ratings for multiple peripheral neuropathies, hypertension, and status post tympanoplasty.

The Board granted a 20 percent initial rating for bilateral dry eye syndrome and service connection for left knee strain, but denied other claims including increased ratings for right lower extremity radiculopathy, bilateral hearing loss, incomplete right bundle branch block (claimed as cardiac arrhythmia), degenerative disc disease of the thoracolumbar spine with IVDS, scarring of the left inguinal area, status post varicocele surgery, and service connection for left shoulder strain and restless leg syndrome.

The Board denied service connection for all the conditions listed as there was no evidence of an in-service event, nor is there evidence demonstrating a nexus to service.

The Board denied service connection for obstructive sleep apnea, bilateral cataracts, dry eye syndrome, allergic conjunctivitis, valvular heart disease, cardiomyopathy, and atrial fibrillation as the evidence did not support a finding that these conditions were incurred in or caused by an in-service event.
