Factors Associated with Ocular Relapse and Visual Prognosis in Sarcoid Uveitis

Area of Science:

• Ophthalmology
• Rheumatology
• Immunology

Background:

• Sarcoid uveitis is a complex intraocular inflammatory condition.
• Understanding relapse factors and visual prognosis is crucial for patient management.

Purpose of the Study:

• To identify factors linked to ocular relapse in sarcoid uveitis.
• To determine the visual prognosis for patients diagnosed with sarcoid uveitis.

Main Methods:

• A multicentric, retrospective cohort study analyzed 336 patients with sarcoid uveitis.
• Ocular relapses and visual impairment were tracked over a median follow-up of 7.8 years.
• Cox proportional hazards models assessed risk factors for relapse and visual impairment.

Main Results:

• Ocular relapses occurred in 66.7% of patients, with a median time to relapse of 2.6 years.
• Macular edema and persistent inflammation at baseline were associated with shorter relapse-free survival.
• Approximately 6% of patients experienced some degree of visual impairment, with glaucoma being a primary cause.

Conclusions:

• Sarcoid uveitis has a high relapse rate, influenced by baseline macular edema and inflammation.
• The majority of patients maintain functional vision, with a low incidence of severe visual impairment or blindness.
