Males comprise 80% of open globe injuries, with men between 10 and 30 years of age at the most significant risk. [5] The mechanism and classification of open-globe injury may also vary by age. Penetrating eye lacerations due to pellet-gun, sport, motor vehicle, or fight-related injuries are more common in adolescent males.
Eye injury by impact of small plastic body. Based on the injury to the eyewall (outer fibrous coat of the eye consisting of cornea and sclera) Closed globe injury: the eye globe is intact, but the seven rings of the eye have been classically described as affected by blunt trauma.
While the vast majority of hyphemas resolve on their own without issue, sometimes complications occur. [1] Traumatic hyphema may lead to increased intraocular pressure (IOP), peripheral anterior synechiae, atrophy of the optic nerve, staining of the cornea with blood, re-bleeding, and impaired accommodation.
Iridodialyses are usually caused by blunt trauma to the eye, [2] but may also be caused by penetrating eye injuries. [7] An iridodialysis may be an iatrogenic complication of any intraocular surgery [10] [11] [12] and at one time they were created intentionally as part of intracapsular cataract extraction. [13]
Tadpole pupil is diagnosed and characterized by the abnormality of the pupil shape. The pupil can disorient itself in different ways before it returns to its original shape. [6] For example, the pupil may stretch out to a 7 o'clock position, [6] i.e. the pupil points in the same direction the hour hand on a clock would at 7 o'clock.
An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall that typically results from the impact of a blunt object larger than the orbital aperture, or eye socket. [1] Most commonly this results in a herniation of orbital contents through the orbital fractures. [ 1 ]
In many cases, only one eye is affected and the person may not be aware of the loss of color vision until the examiner asks them to cover the healthy eye. People may also engage in "eccentric viewing" using peripheral vision to compensate for central vision loss characteristic in genetic, toxic, or nutritional optic neuropathy.
Mydriasis is the dilation of the pupil, usually having a non-physiological cause, [3] or sometimes a physiological pupillary response. [4] Non-physiological causes of mydriasis include disease, trauma, or the use of certain types of drugs.
