Retinal Dialysis After Sports Injuries: The Silent Tear That Expands Over Time

Beware of silent tears and detachments in the retinal periphery resulting from sports injuries and eye contusions. The importance of an urgent fundus examination with Consultant Dr. Mahmoud Hassan.

Retinal Dialysis: The Hidden Danger After Sports Injuries

Sports fields, whether for football, basketball, or even combat sports, are arenas of excitement and challenge, but they can also carry unexpected risks to eye health. Among the injuries that may result from sports-related trauma, retinal dialysis stands out as a condition requiring serious attention due to its silent nature and potential to worsen if not detected and treated early. In this article, we shed light on this type of retinal detachment, its causes after sports injuries, and how to effectively manage it.

What is Retinal Dialysis?

The retina is the thin layer of tissue lining the back of the eye, responsible for capturing light and translating it into nerve signals sent to the brain to form an image. Retinal detachment is divided into several types, and retinal dialysis is a specific type that occurs when the retina tears at its edges, specifically at a region known as the ora serrata, which is where the retina meets the ciliary body. This tear, sometimes referred to as traumatic retinal detachment, may not be accompanied by obvious symptoms initially, making it akin to a "silent tear" that widens over time.

Sports Injuries: The Initial Spark for Retinal Dialysis

Sports involving direct contact or a high probability of injury are among the leading causes of retinal dialysis. When the eye is subjected to severe trauma, such as being hit by a ball in the face or a violent collision during play, the impactful force can cause sudden and acute traction on the retina at its edges. This traction can lead to a tear in the retinal tissue, especially if the retina is weak or predisposed to injury. The most distinctive feature of these injuries is that the tear may not be accompanied by immediate symptoms such as seeing light flashes or floaters noticeably, which delays seeking medical help.

It is worth noting that, even seemingly minor injuries or traumas that do not cause loss of consciousness can be sufficient to cause this type of tear. Therefore, any athlete who experiences eye trauma, no matter how slight, should undergo a thorough eye examination.

Hidden Symptoms of Retinal Dialysis

As mentioned, retinal dialysis is often silent in its early stages. However, some symptoms may appear that should not be ignored, including:

• Blurred or distorted vision: May not be clear initially and worsens over time.
• Appearance of dark spots or moving lines (floaters): May appear suddenly or increase in density.
• Seeing light flashes (photopsia): May be intermittent and not related to the presence of external light.
• Feeling of a curtain or shadow covering part of the field of vision: This is an advanced sign that may indicate the detachment has begun to affect the center of vision.

From a scientific perspective, these symptoms occur due to the effect of vitreous fluid on the torn or detached retina, or as a result of minor bleeding inside the eye. The wider the detachment, the greater the likelihood of the macula (center of vision) being affected, leading to acute vision loss.

Early Diagnosis: The Key to Successful Treatment

Early diagnosis of retinal dialysis is vital to prevent the condition from worsening and to restore vision as much as possible. This requires a thorough fundus examination by a specialized ophthalmologist. Doctors use special instruments such as an ophthalmoscope or an ophthalmoscope with specialized lenses to examine the retinal periphery. In some cases, additional tests may be needed, such as:

• Wide-field Fundus Photography: This examination helps capture comprehensive images of the retina, including the periphery, making it easier to detect any tears or detachments.
• Optical Coherence Tomography (OCT): Provides detailed images of the retinal layers and helps assess the extent of macula involvement.
• Ocular Ultrasound: May be useful in cases where direct examination is difficult due to bleeding or opacity in the cornea or vitreous body.

Consultant Dr. Mahmoud Hassan, a key contributor to Al Mashreq Eye Center, emphasizes the importance of not hesitating to visit an ophthalmologist immediately after any eye injury, especially if the person participates in sports involving a risk of trauma. A comprehensive fundus examination is the first line of defense against this type of silent injury.

Treatment Options for Peripheral Retinal Detachment

The treatment for peripheral retinal detachment depends on the size and location of the tear, and whether a detachment has already occurred. The primary goal is to prevent vitreous fluid from reaching beneath the retina, which could lead to full detachment. Treatment options include:

• Cryopexy: A very cold probe is used to freeze the area around the tear, creating a scar that welds the retina to the back wall of the eye.
• Laser Retinopexy: Lasers are used to heat the area around the tear, forming a scar similar to cryopexy. Retinal Laser Treatment is an effective option for peripheral tears not accompanied by significant detachment.
• Retinal Surgery (Vitrectomy): In cases of advanced or complex detachment, surgery may be needed to remove the vitreous humor, reattach the retina, and then secure it using laser or cryopexy, with a gas or silicone oil injection to support the retina during recovery. The cost of retinal detachment surgery in Egypt for 2026 for complex / tractional / retinal detachment vitrectomy is approximately an average of 50,000 EGP (estimated).
• Scleral Buckle Surgery: A silicone band is placed around the eye to indent the outer wall of the eye, helping to push the eye wall towards the detached retina and reattach it.

The most suitable treatment option is determined by a thorough evaluation of the condition by a retinal surgeon. At El Mashreq Eye Center, the latest technologies are used to ensure the best possible outcomes.

Prevention and Follow-up After Injury

After an eye contusion, even if no obvious symptoms appear, a comprehensive eye examination is strongly recommended. For individuals with a history of retinal problems or those who participate in vigorous sports, prevention is better than cure. This includes wearing appropriate protective eyewear during sports and avoiding sudden or violent head and body movements that may increase eye pressure.

If peripheral retinal detachment is diagnosed, adherence to post-treatment physician instructions, including proper head positioning after surgery, use of prescribed drops, and avoidance of strenuous activities, is crucial for ensuring successful procedure and complete recovery.
