Causes of Cataract The causes of cataracts can be diverse and may vary depending on the type of cataract. Here are some common causes and risk factors associated with cataract development: Age: Aging is the most significant risk factor for cataracts. As people grow older, the proteins in the lens of the eye can break down and clump together, causing clouding and the formation of cataracts.  The majority of cataract cases occur in individuals over the age of 50, and the prevalence…

Cataract refers to a clouding of the lens in the eye leading to decreased vision. The lens is normally clear and helps focus light onto the retina at the back of the eye allowing us to see clearly. However, when a cataract develops, the lens becomes cloudy resulting in blurred or distorted vision. Cataracts can develop in one or both eyes, but it's not necessary for both eyes to be affected simultaneously. It is possible for a cataract to develop in one eye and not the other, or for one eye to…

Can Uveitis be prevented, especially if a person has an auto immune condition? The prevention of uveitis depends on the cause of uveitis in question. The spread of many infections that cause uveitis, can be prevented by putting public health measures in place. Autoimmune conditions that cause uveitis, often have some disease in the rest of the body that require treatment. Anti-inflammatory or immunosuppressive therapy for such diseases, can help in preventing episodes of uveitis. However, there…

Does Lifestyle management play a role in management of Uveitis? In addition to following treatment protocols as described, there is a role for lifestyle modification in many cases. Some forms of uveitis, e.g. HLA-B27 associated uveitis, are triggered by specific factors such as stress or change in diet or season. However, all the factors are not necessarily amenable to lifestyle modification. Smoking has been associated with increased incidence of all anatomical forms of uveitis, and cystoid…

The causes of uveitis can be divided into infectious and non-infectious causes.  Infectious causes: The most common infections that cause uveitis are tuberculosis, viral infections (especially the herpes viruses) and toxoplasmosis. Although nearly any type of infection can enter the eye and cause inflammation. Most patients with infectious uveitis do not have evidence of infection elsewhere in the body. This is a fascinating area for uveitis researchers but very intriguing for the patients…

Treatment options for Uveitis The treatment of uveitis depends on the following four factors: presence or absence of infection, location of uveitis in the eye, severity of inflammation, and the expected progression of the disease. All cases of uveitis, in which an infection is identified, require treatment with the specific antibiotic. The antibiotic is given as tablets, but in some cases, may also be injected into the eye. The inflammation in the eye, in both infectious and non-infectious…

How is Uveitis diagnosed The diagnosis of uveitis largely depends on accurate identification of the pattern of inflammation in the eye. Once the pattern is recognized, specific lab tests are advised to either support or rule out a given diagnosis for the patient. The tests may include blood tests, radiological tests or testing the fluids collected from inside the eye (aqueous or vitreous). This approach is called targeted or tailored testing and is often successful in making the correct…
