What Are Retinal Tears and Retinal Detachments?
The retina is the thin, light-sensitive tissue lining the back of the eye that sends visual signals to the brain. A retinal tear occurs when the retina develops a small break or hole. If untreated, fluid can pass through the tear and cause the retina to lift away from the back of the eye—a serious condition known as a retinal detachment. Retinal detachments are an emergency and can lead to permanent vision loss if not treated promptly.
Why Do Retinal Tears and Detachments Happen?
Retinal tears and detachments often happen due to changes in the vitreous—the gel-like substance inside the eye—that occur with age or after eye trauma. Risk factors include:
- Aging (especially over age 50)
- Severe nearsightedness (myopia)
- Previous eye surgery or injury
- Family history of retinal detachment
- Certain eye diseases
How Do We Test for Retinal Tears and Detachments?
Our ophthalmologist uses a comprehensive dilated eye exam to carefully inspect the retina for any tears, holes, or areas of detachment. Advanced imaging, including Optos widefield retinal imaging, helps capture detailed views of the peripheral retina, ensuring no areas of concern are missed.
Early diagnosis and treatment are critical for the best outcomes. If you experience sudden flashes of light, new floaters, a shadow or curtain over your vision, or any sudden change in vision, seek immediate evaluation.
How Are Retinal Tears and Detachments Treated?
- Retinal Tears: If a retinal tear is detected before it progresses to a detachment, our doctor can often treat it in the clinic using barrage laser therapy. This laser creates a series of tiny burns around the tear, which seal the retina to the underlying tissue and prevent fluid from passing through.
- Retinal Detachments: If a retinal detachment has occurred or if the tear is extensive, surgical repair is necessary. Our retinal specialist performs these procedures at Saskatoon City Hospital, utilizing advanced surgical techniques to reattach the retina and preserve vision.
