Acute angle-closure glaucoma is a rare, but severe form of glaucoma. This type of glaucoma causes no symptoms except for a gradual loss of vision. Most people with glaucoma have "open-angle glaucoma". Contact lenses should not be used during this time. Some bacteria can be extremely aggressive, and the cornea can actually perforate (leading to endophthalmitis, or infection within the eye.) Treatment may include culturing of the corneal infection, and antibiotic eye drops are used very frequently (sometimes every 1/2 hour.) The eye may need to be re-examined on a daily basis to insure that the treatment is being successful. In some contact lens users, the cornea may become somewhat insensitive to pain, and only symptoms of redness and irritation may appear.Ī corneal ulcer is a serious, vision threatening problem.
Symptoms include eye pain, redness, tearing, foreign body sensation, sensitivity to light, and blurred vision.
With the use of extended wear disposable contact lenses, corneal ulcers have become more and more common. A corneal infection occurs when bacteria or fungus are able to gain entry to the cornea through a scratch or breakdown in the corneal surface. Corneal Ulcer (infection)Ī corneal ulcer (or ulcerative keratitis) can cause severe eye pain. Iritis can be associated with inflammatory bowel disease and with arthritis associated with psoriasis. Some infectious diseases such as syphilis, herpes, and toxoplasmosis can cause iritis. These tend to be more common in men than women. Arthritic conditions such as ankylosing spondylitis (a back arthritis) and Reactive Arthritis may be found. Sarcoidosis is a commonly found cause of iritis in adults, more frequently in women. Cases of recurrent iritis, especially severe iritis, and iritis involving both eyes may indicate reason to search for an underlying medical condition. Iritis can be associated with several medical conditions. Oral steroids and other medications (such as dilating eye drops) are sometimes used as well for treatment of iritis. A sudden stoppage of the medication when there is still low-grade (but asymptomatic) iritis can result in a severe flare up of the disease. It is also important not to stop these eye drops suddenly without "tapering off" of the medication. It is important to shake most steroid eyedrop bottles well, since the medication can often settle and become concentrated in the bottom of the bottle. Treatment is with ocular steroids, usually in the form of eye drops. The ophthalmologist can diagnose iritis because inflammatory cells can actually be seen floating in the aqueous humor, which the clear fluid in the front part of the eye. Furthermore, the eye redness in iritis is usually a "flush" of redness in a ring around the cornea. This means that the eye with iritis will feel pain even if light is shined into the OTHER eye only. There are several symptoms of iritis which are fairly specific to it. Anything causing these muscles to work will cause pain. These symptoms occur because the iris and ciliary body both contain muscles which act to control the pupil size and focusing. Inflammation affecting the iris and ciliary body usually lead to symptoms of eye pain, sensitivity to light, pain with focusing, blurred vision, eye redness, and sometimes floaters. This inflammation is similar to arthritis, except that in arthritis a joint is inflamed. In acute iritis, the structures near the front of the eye become inflamed. This is the "uveal tract", and another term for iritis is "uveitis". Iritis usually refers to a group of ocular inflammatory diseases affecting the iris, ciliary body, and choroid. Other conditions causing eye pain or light sensitivity found on other pages.Other conditions capable of causing eye pain that are discussed on other pages of this Symptom and Diagnosis section are listed below with possible distinguishing features. Many of the conditions causing severe eye pain are associated with underlying medical conditions. But severe dry eye will cause eye pain.) This page discusses four conditions that are known to cause severe eye pain. (For example, a dry eye problem usually causes a gritty eye sensation. Almost any eye problem that causes some discomfort can also cause eye pain, if the condition is bad enough.
Ocular pain can originate from many different places: from the eye itself, from the orbit (the bony eye socket), from around the orbit, and even referred from remote areas of the head and neck.
