To support a 10 percent rating, medical records would need to show a diagnosed lacrimal apparatus disorder — such as epiphora or dacryocystitis — affecting one eye. To support a 20 percent rating, the records would need to show the disorder affects both eyes. Useful evidence includes ophthalmology or optometry records documenting the diagnosis, examination findings describing tearing or signs of infection or obstruction, imaging or procedural notes related to the tear ducts, and treatment records. Statements from you or people who know you describing how the condition affects your daily activities — such as blurred vision from tearing or recurring eye infections — can help establish the ongoing presence of the disorder in one or both eyes.
