Old and New Challenges in Uveitis Associated with Behçet's Disease

Behçet's syndrome

Behçet's syndrome is a rare, chronic multisystemic inflammatory disorder also known as the Silk Route disease due to its geographical distribution. Behçet's syndrome is a multifactorial disease and infectious, genetic, epigenetic, and immunological factors contribute to its pathogenesis. Its heterogeneous spectrum of clinical features include mucocutaneous, articular, ocular, vascular, neurological, and gastrointestinal manifestations that can present with a relapsing and remitting course. Differential diagnosis is often hampered by the non-specific clinical presentation and the absence of laboratory biomarkers or pathognomonic histological features. The therapeutic approach is tailored on the basis of patient-specific manifestations and relies on glucocorticoids, colchicine, and traditional and biological immunosuppressants. Despite progress in the knowledge and management of the disease, unmet needs in diagnostics, monitoring, prediction, and treatment personalisation challenge clinical practice, making Behçet's syndrome a complex disorder associated with an increased risk of morbidity.

Novel approach to Behçet's disease in the era of biologic agents

PURPOSE

This review aims to provide better understanding of modern modalities to investigate ocular symptoms of Behçet's disease in order to achieve appropriate management protocols and reduce irreversible visual loss.

RELEVANT FINDINGS

Current methods of diagnosing intraocular involvement in Behçet's disease gives clue to early diagnosis. In addition to standard ocular examination and fluorescein angiography, new noninvasive methods include ocular coherence tomography (OCT) and OCT angiography provide early detection of macular and retinal involvement that can be treated early to improve the prognosis.

SUMMARY

Over the last decade, new multimodal imagings are becoming more accessible; therefore, rapid diagnosis can be made. In addition to newer approved biologic agents, ocular Behçet's disease is seen to be in better controlled with fewer complications.

Behçet's Disease Uveitis

Uveitis in Behçet's disease (BD) is frequent (40% of cases) and is a major cause of morbidity. The age of onset of uveitis is between 20 and 30 years. Ocular involvement includes anterior, posterior, or panuveitis. Uveitis may be the first sign of the disease in 20% of cases or it may appear 2 or 3 years after the first symptoms. Panuveitis is the most common presentation and is more commonly found in men. Bilateralization usually occurs on average 2 years after the first symptoms. The estimated risk of blindness at 5 years is 10-15%. BD uveitis has several ophthalmological features that distinguish it from other uveitis. The main goals in the management of patients are the rapid resolution of intraocular inflammation, the prevention of recurrent attacks, the achievement of complete remission, and the preservation of vision. Biologic therapies have changed the management of intraocular inflammation. The aim of this review is to provide an update to a previous article by our team on pathogenesis, diagnostic approaches, and the therapeutic strategy of BD uveitis.

Two diseases that mimic each other: Behçet disease and sarcoidosis

Behçet syndrome(BS), also known as Behçet disease (BD), is characterized by recurrent oral aphthae and any of several systemic manifestations including genital aphthae, ocular disease, skin lesions, gastrointestinal involvement, neurologic disease, vascular disease or arthritis. Sarcoidosis is a multisystem granulomatous disorder of unknown etiology that affects individuals worldwide and is characterized pathologically by the presence of noncaseating granulomas in involved organs. BD may be confused with sarcoidosis because they are both multisystem inflammatory disorders presenting with uveitis, polyarthritis, meningitis, cardiovascular disease, erythema nodosum, and other cutaneous lesions, and abnormal chest radiographs.
