Visual loss in sarcoid-related uveitis.

Area of Science:

• Ophthalmology
• Immunology
• Systemic Inflammatory Diseases

Background:

• Sarcoidosis frequently involves the eyes, leading to various forms of uveitis.
• Ocular inflammation in sarcoidosis can present with diverse clinical patterns, impacting visual acuity.
• Understanding the visual prognosis associated with different uveitis types in sarcoidosis is essential for patient management.

Purpose of the Study:

• To evaluate visual acuity outcomes in patients with sarcoidosis-associated uveitis.
• To identify sight-threatening complications associated with different uveitis subtypes.
• To compare the risk of poor visual outcomes across various types of uveitis in sarcoidosis.

Main Methods:

• Retrospective, non-comparative, interventional study.
• Inclusion of patients with confirmed sarcoidosis and uveitis, with a minimum 6-month follow-up.
• Analysis of visual acuity changes and complications, using logistic regression to control for prognostic factors.

Main Results:

• Seventy-five patients were analyzed, exhibiting a wide spectrum of ocular inflammation.
• Poor visual outcomes were significantly more frequent in multifocal choroiditis (71.4%) and panuveitis (46.4%) compared to anterior uveitis (12.5%).
• Cataract, glaucoma, macular edema, vitreous hemorrhage, and retinal detachment were identified as causes of visual loss.

Conclusions:

• Multifocal choroiditis, though less common, is linked to a worse visual prognosis in sarcoidosis-associated uveitis.
• Panuveitis also carries a significant risk of poor visual outcomes.
• Despite immunosuppressive therapy, certain uveitis types in sarcoidosis present a challenge for visual preservation.
