The OCT images (A, C, E) of 3 patients who underwent vitrectomy due to rheumatogenic retinal detachment and developed macular hole afterwards are shown below. Could you determine the finding indicated by a white arrow on the OCT sections?
The answer to the question is “Foveal Crack Sign’’. As a result of the lottery drawn among those who answered the question correctly, Dr. Mehmet Cem Sabaner won this month’s book prize. Congratulations to him.
“Foveal Crack Sign” is an OCT finding that occurs before the macular hole develops after vitrectomy due to rhegmatogenous retinal detachment.
