Retinal traction is a pulling force on the retina, usually from vitreous gel or scar tissue attached to the retinal surface. The pull can warp retinal layers and affect how light signals are processed. If the pull is strong, it can lift the retina and lead to tractional retinal detachment. Risk depends on where the traction is located and whether it threatens the macula.
read more about retinal traction ...Retinal traction often starts when membranes form on the retinal surface and slowly contract. Proliferative diabetic retinopathy is a common cause because fibrovascular tissue can tighten over time. Scarring after a retinal detachment can also create traction. Vitreomacular traction can happen when the vitreous stays partly attached to the macula instead of separating cleanly.
Symptoms depend on whether traction affects central or peripheral retina. When the macula is involved, straight lines can look wavy and central vision can turn blurry. Some people notice a gray spot or trouble reading with one eye. If traction progresses to detachment, a shadow or curtain-like area can appear in vision.
Diagnosis starts with a dilated eye exam to look for membranes, areas of pull, and any sign of retinal elevation. OCT imaging is often used to show traction patterns and macular distortion in detail. Fluorescein angiography can be used when proliferative disease is suspected because it maps leakage and ischemia. Ocular ultrasound can help when a clear view of the retina is blocked by vitreous hemorrhage or dense cataract.
Treatment depends on the cause, the location of traction, and how much vision is affected. Mild traction that is stable and not threatening the macula is sometimes monitored with repeat exams and OCT. When proliferative diabetic retinopathy is present, injections and laser treatment are often used to reduce active disease and bleeding risk. If traction threatens or involves the macula, vitrectomy with membrane peeling may be recommended to relieve the pull.
No. Retinal traction describes a pulling force on the retina, while tractional retinal detachment happens when that pull lifts the retina off the layer beneath it. Traction can exist without a detachment, especially early on. A dilated exam and imaging such as OCT help show whether detachment is present.
Yes. Proliferative diabetic retinopathy can lead to abnormal new vessels and fibrous tissue on the retina. As that tissue contracts, it can pull on the retina and create traction. Severe traction can also cause a tractional retinal detachment that often needs specialist care.
Surgery is considered when traction threatens or involves the macula, when vision is declining, or when a tractional detachment is present. Vitrectomy can remove the vitreous scaffold and peel membranes that are tightening the retina. Timing depends on how close traction is to the macula and how fast findings are changing. A retina specialist weighs expected benefit against surgical risks based on the exam and imaging.
