Optical coherence tomography findings in autoimmune retinopathy

Area of Science:

• Ophthalmology
• Medical Imaging
• Immunology

Background:

• Autoimmune retinopathy (AIR) is an immune-mediated condition causing progressive vision loss.
• Diagnosis often relies on clinical presentation, electroretinography (ERG), and antibody testing.
• Objective imaging biomarkers are crucial for understanding disease progression.

Purpose of the Study:

• To characterize the optical coherence tomography (OCT) findings in patients diagnosed with autoimmune retinopathy.
• To correlate OCT features with clinical manifestations of vision impairment.

Main Methods:

• A consecutive case series of eight patients with unexplained vision loss was analyzed.
• All patients underwent macular and nerve fiber layer (NFL) OCT.
• Diagnosis of AIR was confirmed by clinical features, ERG, and serum antiretinal antibodies.

Main Results:

• All patients exhibited outer retinal abnormalities and/or reduced macular thickness on OCT.
• Six patients showed decreased central macular and foveal thickness.
• Photoreceptor layer disruption was observed in most patients, with some showing NFL loss.

Conclusions:

• Optical coherence tomography demonstrates predominant retinal atrophy and reduced macular thickness in autoimmune retinopathy.
• OCT provides objective, quantifiable data on retinal damage in AIR.
• OCT findings may aid in diagnosing autoimmune retinopathy and elucidating visual dysfunction mechanisms.
