Looking at the OCT image, could you describe the finding in this patient with diabetic macular edema?
Thanks to everyone who showed interest in the section of question of the month and answered the question. In this month’s question, description of the finding on the OCT image in the patient with diabetic macular edema was asked.
The answer to the question is ‘’ Pearl Necklace Sign’’. The result of the lottery among those who answered the question correctly, the winner of this month’s book prize is Dmytro Martynov. Congratulations to him.
Hyperreflective dots arranged as a contiguous ring along the inner wall of cystoid spaces on the macular OCT scan, termed as the pearl necklace sign, are commonly seen in DMO patients who require intravitreal treatment. With a resolution of edema, hard exudates frequently appear in the same location on the retina, implying that the pearl necklace sign is a precursor to hard exudates, in the majority of cases.
