Is iritis serious?

The severity of iritis varies among individuals and depends on the progression of the condition. Iritis is an eye disease that requires prompt attention. It may lead to various complications, including vision loss, spread of intraocular inflammation, secondary glaucoma, corneal ulcers, and uveitis. Vision impairment is one of the most common symptoms of iritis, potentially causing temporary blurred vision or visual field defects. If iritis is not promptly controlled, the inflammation may spread to other parts of the eye, leading to more serious complications such as widespread intraocular inflammation and secondary glaucoma, which can cause symptoms like eye pain, headache, nausea, vomiting, and sudden vision deterioration. The treatment principle for iritis is "the earlier, the better," in order to minimize the risk of complications. Patients with mild symptoms can often be managed with medications, such as dexamethasone eye drops, to relieve symptoms. However, in more severe cases, surgical intervention—such as corneal paracentesis—may be necessary.
