The accessory visual structures (or adnexa of eye, ocular adnexa, etc.) are the protecting and supporting structures (adnexa) of the eye, including the eyebrow, eyelids, and lacrimal apparatus. The eyebrows, eyelids, eyelashes, lacrimal gland and drainage apparatus all play a crucial role with regards to globe protection, lubrication, and minimizing the risk of ocular infection.^[1] The adnexal structures also help to keep the cornea moist and clean.

One source defines "ocular adnexa" as the orbit, conjunctiva, and eyelids.^[2] The orbit and extraocular muscles allow for the smooth movement of the eyeball.
