Understanding Retinal Scarring

Your retina is a vital part of your vision, acting like a camera sensor that captures images and sends them to your brain. But when scarring develops on the retina, it can interfere with sight, causing distortions or even vision loss.

Retinal scarring occurs when fibrous tissue forms on the retina, the light-sensitive layer at the back of the eye. Depending on its location and severity, scarring can cause little to no symptoms or significantly impact vision. In some cases, it may lead to conditions such as epiretinal membranes (ERM) or proliferative vitreoretinopathy (PVR), both of which can distort or blur vision.

Retinal scarring can develop due to various eye conditions, injuries or diseases. One of the most common causes is eye trauma, where physical injury to the eye can trigger scar formation. Retinal tears or detachments may also lead to scarring as the eye heals after the retina pulls away from its normal position. Inflammatory diseases, such as uveitis or diabetic retinopathy, can cause damage that results in scarring. Additionally, infections like toxoplasmosis may lead to inflammation, which can contribute to scar tissue formation. In some cases, surgical complications from previous eye surgeries, including retinal detachment repairs, may also result in scarring.

The symptoms of retinal scarring vary depending on the location and severity of the scar. Some individuals may not notice any vision problems, while others might experience blurred or distorted vision, making it difficult to see fine details or read. Some may also notice dark spots or floaters, which can appear as small shadows or specks drifting across their vision. In more severe cases, vision loss may occur, significantly impacting daily activities and overall eye health.

Treatment for retinal scarring depends on its severity and impact on vision. In mild cases, no immediate intervention may be necessary, and regular monitoring by an eye specialist may be recommended. However, if the scarring begins to affect vision, several treatment options are available. Medications, such as anti-inflammatory or steroid treatments, may help reduce swelling and prevent further scar formation. In some cases, laser therapy can be used to control retinal damage and limit its progression. For more severe scarring that significantly impairs vision, vitrectomy surgery may be performed to remove the scar tissue and restore visual clarity. The appropriate treatment approach is determined based on individual patient needs and the extent of retinal damage.

While not all causes of retinal scarring can be avoided, taking steps to protect your eye health can reduce the risk. Managing conditions like diabetes, seeking prompt treatment for eye infections and protecting your eyes from injury can help maintain clear vision.
If you’re experiencing vision changes or have concerns about retinal scarring, it’s essential to see an eye specialist for a thorough evaluation. Early detection and treatment can make all the difference in preserving your sight. Contact Associated Retina Consultants at 602-242-4928 or WEBSITE to schedule your appointment.
