The lateral sulcus separates the frontal lobe from the temporal lobe. The frontal lobe can be divided into a lateral, polar, orbital (above the orbit; also called basal or ventral), and medial part. Each of these parts consists of a particular gyrus: 1  Lateral part: lateral part of the superior frontal gyrus, middle frontal gyrus, inferior frontal gyrus. 2  Polar part: Transverse frontopolar gyri, frontomarginal gyrus. 3  Orbital part: Lateral orbital gyrus, anterior orbital gyrus, posterior orbital gyrus, medial orbital gyrus, gyrus rectus.
Less common causes of glaucoma include a blunt or chemical injury to the eye, severe eye infection, blockage of blood vessels in the eye, inflammatory conditions of the eye, and occasionally eye surgery to correct another condition.
As a result of an immediate injury, traumatic glaucoma is most commonly caused by blunt trauma, which is an injury that doesnât penetrate the eye, such as a blow to the head or an injury directly on the eye. The most common cause is from sports-related injuries, such as baseball or boxing.
