Ernstige visusdaling door auto-immuunretinopathie

Background

Autoimmune retinopathy (AIR) is a rare disorder which may present as a paraneoplastic syndrome. AIR is associated with the presence of anti-retinal antibodies. These antibodies are assumed to cause damage to the retina, resulting in progressive vision loss.

Case description

A 74-year-old man visited the ophthalmologist with a serious, progressive loss of vision, without any noteworthy abnormalities at routine ophthalmological examination. The electroretinogram was characteristic of loss of photoreceptor function. Anti-retinal antibodies against recoverin were detected in serum. After referral to an internist on account of a suspected diagnosis of paraneoplastic AIR, the patient was diagnosed with a lung carcinoma, confirming the diagnosis of cancer-associated paraneoplastic AIR.

Conclusion

An unexplained loss of vision is highly suggestive of paraneoplastic AIR, even in patients without a known malignancy. Laboratory techniques for the detection of the anti-retinal antibody against recoverin have recently been implemented in the Netherlands, facilitating the diagnosis of AIR.
