The eye resembles a tennis ball in shape, comprising three distinct layers of tissue encompassing the gel-filled central cavity. At the core lies the retina, responsible for light perception and image transmission to the brain. Enclosed between the sclera and the retina, the uvea constitutes the middle layer. The outermost layer, the sclera, forms the robust white exterior of the eye. Uveitis, pronounced as you-vee-EYE-tis, denotes inflammation specifically affecting the uvea.
The Importance of the UVEA
The uvea harbors numerous blood vessels including veins, arteries, and capillaries, which facilitate the transportation of blood to and from the eye. Given that the uvea sustains crucial components of the eye, such as the retina, inflammation within this region can lead to impaired vision.
The Symptoms of Uveitis
- light sensitivity.
- blurred vision.
- pain.
- floaters.
- redness of the eye.
Uveitis can manifest abruptly, presenting symptoms such as redness and pain, or it may onset subtly with painless vision impairment.
What might seem like a minor issue, such as a simple case of “red eye,” could actually indicate a significant problem like uveitis. Therefore, if you experience redness or discomfort in your eye, it’s crucial to seek evaluation and treatment from an ophthalmologist (Eye M.D.).
Causes of Uveitis
- virus, such as shingles, mumps, or herpes simplex.
- a fungus, such as histoplasmosis.
- a parasite, such as toxoplasmosis.
- related disease in other parts of the body, such as arthritis, gastrointestinal disease, or collagen vascular disease such as lupus.
- a result of injury to the eye.
Most cases of uveitis, the cause of the disease remains unknown.
Diagnostic Procedures of Uveitis
When symptoms arise, a thorough examination conducted by an ophthalmologist is paramount. If left untreated, inflammation within the eye can cause lasting damage to vision or potentially result in blindness.
During the examination, your ophthalmologist will inspect the interior of your eye. Additional diagnostic measures such as blood tests, skin tests, or x-rays may be prescribed to aid in diagnosis.
As uveitis can be linked to systemic conditions, your ophthalmologist will inquire about your overall health status. Collaboration with your primary care physician or other medical specialists may be sought to ensure comprehensive care.
Types of Uveitis
Various forms of uveitis exist, determined by the specific area of the eye that is impacted.
Iritis
When inflammation occurs in the iris, the front portion of the uvea, it is referred to as iritis. Iritis typically manifests suddenly and can persist for a duration of six to eight weeks.
Cyclitis
When inflammation occurs in the middle portion of the eye involving the uvea, it is termed cyclitis. This condition impacts the muscle responsible for lens focusing. Cyclitis can also emerge abruptly and may endure for several months.
Choroiditis
Inflammation at the posterior part of the eye is referred to as choroiditis. Choroiditis tends to develop gradually and can have a prolonged duration.
Uveitis Treatment
Uveitis is a serious eye condition that can lead to scarring if left untreated. Prompt treatment is imperative.
Treatment for uveitis typically involves the use of eyedrops, particularly corticosteroids and pupil dilators, to alleviate inflammation and discomfort. In instances of severe inflammation, oral medication or injections may be required for management.
These Complications May be Associated with Uveitis
- glaucoma (increased pressure in the eye).
- cataract (clouding of the eye’s natural lens).
- neovascularization (growth of new, abnormal blood vessels).
- damage to the retina, including retinal detachment.
Treatment for these complications may involve the use of eyedrops, traditional surgery, or laser surgery.
Should you experience a persistent “red eye,” it’s advisable to reach out to your ophthalmologist promptly.
