Entitlement to service connection for left eye cataract is denied.

Board reasoning

The Board found no service connection for left eye cataract because there is no in-service incurrence or nexus supported by the record, and no examiner-required link was indicated under McLendon. For herpes, the Board concluded there was no current herpes diagnosis during the period on appeal and no nexus, citing lack of persistent disability. Regarding PTSD, the Board determined the psychiatric symptoms during the rating period did not meet the criteria for a higher than 50 percent rating, noting the December 2020 examination and subsequent treatment showed impairment compatible with 50 percent rather than 70 or 100 percent, and that medication use did not justify a higher rating under the General Formula.
