A blind spot or area of reduced vision within the visual field of one eye.
To support a 10% rating, medical records and eye examination findings should document the size and location of the scotoma. A visual field test — such as a Goldmann or automated perimetry exam — is the key piece of evidence, because it maps the blind spot and shows whether it covers at least one-quarter of the visual field or sits in the central zone of vision.
If the scotoma affects your visual acuity, records of Snellen chart testing or other standardized acuity measurements can help VA apply the visual impairment formula and potentially reach a higher rating. Ophthalmology or optometry notes describing how the blind spot affects your ability to read, drive, work, or perform daily tasks can also support the overall picture of functional loss. Statements from you or people who observe you regularly can describe real-world effects that clinical numbers alone may not fully capture.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
