Pain in the orbital area is usually due to the following reasons: 1. Involvement pain due to elevated intraocular pressure in glaucoma. When the IOP is mildly elevated, it is mainly manifested as soreness in the orbit, and when the IOP is severely elevated, it is distension and pain in the orbital area. 2. caused by visual fatigue. When the eye is focused on a near object for a long time, it will cause spasm of the ciliary muscle, which will lead to spasm pain and also cause radiating pain to the orbital area. 3, caused by trigeminal neuralgia. 3, caused by trigeminal neuralgia, the supraorbital and infraorbital branches of the trigeminal nerve are responsible for the sensation of the upper and lower part of the orbital area respectively, once trigeminal neuralgia occurs, it will definitely lead to orbital pain. 4, caused by sinusitis. The sinuses are divided into multiple groups, which are distributed in the upper, lower and inner parts of the orbit. When one or more of these groups of sinuses become inflamed, it will trigger orbital pain.
