Orbicularis oculi is the muscle surrounding the eye.
The little circle muscle of the eye.
Orbicularis oculi is a skeletal muscle of the face that surrounds the eye and is responsible for closing the eye.
Injury to the orbicularis oculi can result from overuse, which may result in headaches, eyestrain, or sinus headaches. The main cause for overuse of this muscle is poor eyesight without the proper corrective lenses. If eyesight is not corrected then the eyes strain in order to try to see better, which uses the orbicularis oculi. NSAIDs, like ibuprofen, will help with headaches and proper eyewear may prevent strain. If left untreated, the orbicularis oculi can cause crow’s feet to develop.

Previously conducted eyelid surgeries used techniques based on the premise that the nerves to the orbicularis oculi muscle approach it from the lateral and that the segmental fascicles go parallel to the muscle fibres. Surgeries based off this premise have many issues including ectropion, the flipping of the eyelids so the inward part is exposed, and other incorrect eyelid positions. An anatomical study indicated that techniques using the approach through the lower eyelid might change the innervation of orbicularis oculi muscle. This innervation change would put the muscle at a much higher risk for complications.

Blepharoptosis occurs when the upper portion of the eyelid is less than 2.0 mm from the mid-pupil or there is more than 2.0 mm of asymmetry between the two eyelids. This condition has been a challenge for surgeons due to the complications that may arise from conventional surgeries. Due to previous research, the conclusion came to develop a Frontalis-Orbicularis Oculi Muscle (FOOM) flap-shortening technique. This technique allows for the harvesting of the FOOM flaps and the adjustment of the flaps depending on the severity of the condition. The procedure prevents the eye from closing or drooping involuntarily and enhances the ability to keep the eye wide open. This study showed that the procedure yielded good results with the biggest issue being under-correction.

Orbicularis oculi exercises
The eyelid squeeze
Begin by placing the fingertips on the eyebrows. Close the eyelids and squeeze tightly. Hold the position for forty seconds. Practice this exercise five times a day.
Begin sitting with good posture. Raise the eyebrows up as far as possible and open the eyes widely. Hold this position for ten seconds, release for five seconds, and then repeat ten times. Perform this exercise daily.
