Question:
A 50-year-old female patient with 20/20 vision, who has been using 400 mg of hydroxychloroquine per day for 8 years due to Sjögren’s syndrome. Looking at the OCT and fundus autofluorescence images, could you determine the diagnosis and finding on the OCT image?
Answer:
The answer to the question is ‘’ Hydroxychloroquine Retinopathy/Flying Saucer Sign’’. As a result of the lottery drawn among those who answered the question correctly, Mr. Muzaffer Ozturk won this month’s book prize. Congratulations to him.
” Flying Saucer Sign” is a definition given to the ovoid appearance of the fovea caused by the thinning of the outer retinal layers with the loss of photoreceptors and ellipsoid zone in the perifoveal area by protecting the outer retina structures in the foveal area.
