What is uveitic glaucoma?
Uveitic glaucoma is a complex and challenging type of secondary glaucoma caused by uveitis, an inflammatory condition that affects the uvea, which includes the eye’s iris, ciliary body, and choroid. Uveitis can cause inflammation in various parts of the eye, resulting in elevated intraocular pressure (IOP), which, if left untreated, can damage the optic nerve and cause vision loss. Uveitic glaucoma combines the complications of glaucoma and uveitis, making it extremely difficult to treat.
This condition can affect people of all ages, but it is more common among young and middle-aged adults. Uveitis-related inflammation can cause structural changes in the eye, such as the formation of synechiae (adhesions between the iris and lens), blockage of the trabecular meshwork (the eye’s drainage system), and the development of neovascularization. These changes can prevent the normal outflow of aqueous humor, resulting in elevated IOP.
Symptoms of uveitic glaucoma include eye pain, redness, blurred vision, halos around lights, and migraines. Because of the condition’s dual nature, a comprehensive diagnostic approach is required, which includes a detailed medical history, a thorough ocular examination, and the use of imaging modalities such as optical coherence tomography (OCT) and ultrasound biomicroscopy.
Early detection and treatment are critical to avoiding irreversible vision loss. Understanding the pathophysiology, risk factors, and symptoms of uveitic glaucoma is critical for effective treatment and better patient outcomes.
Effective Management of Uveitic Glaucoma
Managing uveitic glaucoma necessitates a multifaceted approach that addresses both underlying uveitis and elevated intraocular pressure. Treatment strategies must be tailored to each patient’s specific needs, taking into account the severity of the inflammation, the level of IOP elevation, and the overall health of the eye.
Anti-Inflammatory Medications: The primary goal of treating uveitic glaucoma is to reduce inflammation. Corticosteroids are the primary treatment and are available in a variety of forms, including topical eye drops, oral medications, and intraocular injections. Nonsteroidal anti-inflammatory drugs (NSAIDs) can also help to reduce inflammation. Immunosuppressive agents such as methotrexate and cyclosporine, as well as biologic agents such as adalimumab, may be used to treat chronic or severe uveitis.
Medications for Lowering Intraocular Pressure: To treat elevated IOP, a combination of medications may be used. These include prostaglandin analogs, beta-blockers, alpha agonists, carbonic anhydrase inhibitors, and Rho kinase inhibitors. These drugs help to reduce aqueous humor production or increase its outflow, lowering IOP.
Laser Therapy: Laser treatments can help manage uveitic glaucoma. Selective laser trabeculoplasty (SLT) is a procedure that focuses on the trabecular meshwork to improve aqueous outflow and reduce IOP. Another laser treatment for reducing aqueous humor production is cyclophotocoagulation, which targets the ciliary body.
Surgical Interventions: In cases where medical and laser therapies fail to control IOP, surgical options may be considered. Trabeculectomy is a common procedure that opens up a new drainage pathway for aqueous humor. Ahmed or Baerveldt implants, for example, can divert fluid and lower IOP. For patients with severe inflammation and advanced glaucoma, cyclodestructive procedures that reduce the ciliary body’s ability to produce aqueous humor may be required.
Monitoring and follow-up: Patients with uveitic glaucoma require regular monitoring. Frequent eye examinations, IOP measurements, visual field tests, and imaging studies are required to assess treatment effectiveness and make necessary adjustments.
