The eye is a region of mostly calm weather at the center of a tropical cyclone. The eye of a storm is a roughly circular area, typically 30–65 kilometers (19–40 miles; 16–35 nautical miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds of the cyclone occur.
Traumatic eye injury can cause intraocular hemorrhage in people of any age and gender. However, injuries tend to be more common in young males due to more outdoor activities and heavy work. They are also more common in children during the summer. The incidence of traumatic hyphema is approximately 12 per 100,000.

There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
Symptoms of an open-globe injury include eye pain, foreign body sensation, eye redness, and blurry or double vision. [9] While globe injuries are commonly associated with peri-ocular trauma that may obstruct diagnosis, [4] several signs suggest open-globe damage: Visible corneal or scleral laceration; Sub-conjunctival hemorrhage; Protruding ...
Sympathetic ophthalmia (SO), also called spared eye injury, is a diffuse granulomatous inflammation of the uveal layer of both eyes following trauma to one eye. It can leave the affected person completely blind. Symptoms may develop from days to several years after a penetrating eye injury. It typically results from a delayed hypersensitivity ...
Indirect injuries, like blunt trauma to the forehead during a motor vehicle accident, transmit force to the optic nerve without transgressing tissue planes. This type of force causes the optic nerve to absorb excess energy at the time of impact. The most common site of injury of the optic nerve is the intracanalicular portion of the nerve.
