Macular puckers, also referred to as epiretinal membranes, are a type of scar tissue that forms over the macula, appearing as bulges or wrinkles in the macular tissue. In their most severe form, macular holes can result in the vitreous gel separating from the optic disc, leading to serious vision loss. As this occurs, visual acuity declines at a noticeable rate. At this point, these defects can sometimes heal on their own but often progress to the next phase of damage if left untreated.Įventually, once the macular hole appears, it begins to increase in thickness. As the contour flattens, small defects appear in the macula. Macular holes are a progressive condition that generally starts with the fovea losing its contour. Macular holes are often caused by the tractional force created in PVD. When a small break or tear occurs in the macula, it is known as a macular hole. This can lead to structural damage of the retina, retinal tear or detachment, and other macular complications, including macular holes and macular puckers. However, if the vitreous gel is partially connected to the retinal tissue, it can create a tractional force that tugs at the retina. Most of the time, this happens without causing any issues. PVD is a normal process of aging in which the vitreous gel contained within the posterior segment of the eye diminishes in both quantity and thickness. Vitreomacular traction syndrome (VMT) is a retinal disorder that is commonly associated with posterior vitreous detachment (PVD). DME can eventually lead to permanent vision loss. This occurs when high levels of blood glucose damage the retinal blood vessels, causing them to leak into the macular region and cause swelling. When macular edema is caused by diabetic retinopathy, it is known as diabetic macular edema (DME). Macular edema, which is swelling of the macula caused by excessive fluid buildup, is commonly found alongside many other eye conditions, such as:
