Presumed vascular traction-associated recurrence of retinal detachment in patients with myopic macular hole.

Optical coherence tomography (OCT) and OCT-ophthalmoscopic examinations were consecutively performed in two patients with focal retinal redetachment despite previously successful repair of the myopic macular hole-related retinal detachment by vitrectomy with removal of the internal limiting membrane. A microfold developed on the redetached retinal surface in both eyes soon after surgery. C-scan analysis by OCT-ophthalmoscope showed that the retinal microfolds coincided with a retinal artery adjacent to the preexisting macular hole. OCT revealed the focal retinal detachment was most prominent beneath the retinal microfold in both study eyes and did not reach the macular hole in one eye. The retinal microfold was most marked at the initiation of the recurrence and then attenuated with the elevation of the detached retina. Inward vascular tractional force appearing as a retinal microfold can be a critical trigger of recurrent retinal detachment in patients with myopic macular hole.
