Clinical Features of Behçet's Disease Uveitis

Behçet's disease (BD) is a chronic, multisystemic vasculitis first described by Professor Hulusi Behçet in 1937. It is characterized by recurrent inflammatory attacks affecting multiple organs, with uveitis being a significant and severe complication that can lead to blindness. BD typically emerges between the ages of 20 and 30 years, with a higher prevalence in males and rare occurrences in children. The prevalence and severity of BD and its ocular symptoms tend to diminish with age. In Turkey, BD is a leading cause of noninfectious uveitis, and its prevalence varies across different regions. Ocular involvement, seen in up to 90% of BD patients, often appears 2-4 years after disease onset and may be the initial sign in 10%-20% of cases. BD uveitis is characterized by recurrent nongranulomatous panuveitis and retinal vasculitis, typically affecting both eyes. Diagnostic tools such as fluorescein angiography (FA), optical coherence tomography (OCT), and laser flare photometry (LFP) are essential for monitoring disease activity and guiding treatment. FA is crucial for identifying occlusive and leaky vasculitis, while OCT helps in detecting macular complications and visualizing retinal infiltrates and their sequelae. LFP quantitatively evaluates intraocular inflammation. Recognizing the ocular manifestations of BD early is vital for accurate diagnosis and effective management. This review highlights the clinical features, diagnostic tools, and importance of early diagnosis in managing BD uveitis.
