The Board remands the claims for service connection for bilateral dry eye syndrome and left eye pterygium due to a need for additional medical evidence.

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 various conditions and denied increased ratings for several service-connected disabilities, as the evidence did not support a finding of current disability or aggravation related to service.
