OCT (Optical Coherence Tomography) is a scan of the retina, used to examine and visualize the different parts of the eye. This imaging has made it possible to observe the retina to detect refined uplifts, diabetic retinopathy, and more. It is used to monitor the retina to identify if treatment is needed. OCT is also used extensively to examine the optic nerve and is an excellent screening tool for glaucoma.

A study was carried out using OCT to accurately describe an image VMT based on anatomic features. There have been subsequent studies using OCT to determine the anatomical changes associated with VMT, reporting that the traction force on the macular is associated with the progression and development of VMT.

The study was focused on the proliferative changes at the vitreoretinal interface that could intentionally impact the fractional forces created by the posterior vitreous currents. The VMT cases were characterized by proliferative or nonproliferative, depending on the thickened posterior vitreous. Wide-angled OCT images were used, taking advantage of vertical and horizontal scans of fifty eyes from forty-six VMT patients. They also carried out eye tracking and baseline fundus scans. The scans were superimposed to compare any changes to the position and contour of the posterior vitreous.

The researchers found that forty-eight percent of patients had proliferative VMT and fifty-two percent had nonproliferative VMT. The epiretinal membrane was noted in twenty-six percent of the nonproliferative eyes and ninety-five percent of the proliferative eyes. Patients with proliferative VMT did not have wavy posterior vitreous and had no motion-induced changes of the posterior vitreous when eye movement was followed.

Fifty-seven percent of patients with nonproliferative VMT had wavy posterior vitreous and ninety-one percent had motion-induced changes of the posterior vitreous when the eye movement was followed. Thirty-four percent of the nonproliferative eyes and eight percent of the proliferative eyes had posterior vitreous detachment that went beyond the scanned area.

The PA to Mahi Muqit, Ray Man, said “The eyes that had nonproliferative VMT had flexible and mobile vitreous when they eye moved, where proliferative VMT eyes were thickened and static. The thickened posterior vitreous at the macular could play an important role in macular pathology. Patients with proliferative VMT pathological changes had strong adhesion at the fibrous anchors, limiting posterior vitreous detachment.”
