Noninfectious Uveitis Syndromes.

Area of Science:

• Ophthalmology
• Immunology
• Retinal Diseases

Background:

• Noninfectious uveitis encompasses a heterogeneous group of disorders affecting the retina and choroid.
• Etiology is often unknown, though autoimmune pathogenesis is postulated, and some cases follow flu-like illnesses.
• These conditions typically affect individuals in their 2nd to 5th decades, with some syndromes showing a female predilection.

Purpose of the Study:

• To review the clinical presentation, diagnostic approaches, and prognostic variability of noninfectious uveitis syndromes.
• To highlight the role of multimodal imaging in diagnosing these often-subtle retinal and choroidal conditions.
• To provide an overview of the diverse clinical spectrum and outcomes associated with noninfectious uveitis.

Main Methods:

• Review of clinical features, including patient demographics and presenting symptoms like photopsias and decreased visual acuity.
• Analysis of fundus findings, characterized by bilateral (except MEWDS) but potentially asymmetric yellow-white lesions in the outer retina, RPE, and choroid.
• Emphasis on multimodal imaging techniques for lesion detection and electrophysiological assessments to evaluate retinal function.

Main Results:

• Fundus lesions, often more apparent on imaging than clinically, are typically bilateral and located in the outer retina, RPE, and choroid.
• Multimodal imaging reveals distinct patterns for different uveitis syndromes, aiding in diagnosis.
• Electrophysiology results vary, ranging from normal to markedly attenuated, depending on the specific syndrome.

Conclusions:

• Noninfectious uveitis presents heterogeneously with variable clinical findings and imaging patterns.
• Multimodal imaging is crucial for accurate diagnosis and understanding the extent of retinal and choroidal involvement.
• Prognosis is highly variable, ranging from spontaneous resolution to progressive, irreversible vision loss.
