Trauma-Induced Giant Retinal Tear: A Surgical Emergency to Prevent Complete Retinal Detachment

When a severe blow causes a giant retinal tear exceeding 90 degrees, Dr. Mahmoud Hassan explains the protocol for heavy liquid retinal reattachment and silicone oil injection.

Traumatic Giant Retinal Detachment: A Surgical Emergency to Prevent Complete Retinal Collapse

Eye injuries, especially those resulting from direct trauma or violent accidents, are medical conditions that require prompt and decisive intervention. Among the most dangerous and urgent of these injuries is what is known as traumatic giant retinal detachment. This condition, which can extend over more than 90 degrees of the retinal circumference, represents a significant surgical challenge, as neglecting it or delaying its treatment can lead to dire consequences, including complete retinal collapse and permanent vision loss. In this article, we review the nature of this injury, the importance of rapid surgical intervention, and the advanced techniques used at Al-Mashreq Eye Center in Cairo, led by Dr. Mahmoud Hassan, who is considered one of the key contributors to the development of retinal surgery services at the center.

What is Traumatic Giant Retinal Detachment?

The retina is the thin, light-sensitive tissue lining the back of the eye, responsible for capturing images and sending them to the brain via the optic nerve. When the eye experiences severe trauma, such as a direct blow or a car accident, this force can cause the retina to tear or detach from the eye wall. In cases of giant retinal detachment, this tear is very wide, often exceeding a quarter of the retinal circumference (more than 90 degrees), significantly increasing the risk of complete retinal detachment.

Multiple causes of trauma can lead to this condition, including:

• Direct blows to or around the eye.

• Car accidents or falls from heights.

• Work-related injuries or violent sports.

• Explosions or sudden severe impacts.

It is worth noting that other risk factors such as severe myopia, a previous history of retinal detachment, or specific retinal weakness, may increase the likelihood of extensive retinal detachment after trauma.

Why is Giant Retinal Detachment an Emergency?

The main danger of giant retinal detachment lies in its rapid progression to complete retinal detachment. When a wide tear occurs, the fluid inside the eye (vitreous humor) can seep through this tear, leading to the complete separation of the retina from its supporting layers. This detachment deprives the retinal cells of oxygen and nutrients, leading to their damage and permanent loss of function if not promptly intervened. Therefore, any giant retinal detachment, especially if caused by trauma, is considered a surgical emergency requiring immediate assessment and meticulous treatment planning.

Scientifically, the speed of restoring the retina to its place and preventing fluid leakage underneath is key to preserving its sensitive cells. Every hour of delay increases the difficulty of surgery and reduces the chances of full vision recovery.

Advanced Surgical Techniques at Al-Mashreq Eye Center

In cases of traumatic giant retinal detachment, the retinal surgery team at Al-Mashreq Eye Center, led by Dr. Mahmoud Hassan, relies on the latest surgical techniques to ensure the best possible outcomes. The primary goal is to return the retina to its normal position, repair the tear to prevent re-detachment, and restore vision as much as possible.

1. Vitrectomy Surgery

Pars plana vitrectomy (PPV) is the cornerstone in treating most cases of retinal detachment, especially complex ones like giant retinal detachments. During this surgery, the cloudy or traction-causing vitreous humor is replaced with a sterile saline solution or gas. This technique allows the surgeon a clear view of the retina and the removal of any membranes or fibrosis that might prevent the retina from reattaching.

2. Retinal Flattening with Heavy Liquid Perfluorocarbon

In cases of giant retinal detachment, it can be difficult to flatten the retina completely using gas alone due to the size of the tear or the nature of the injury. This is where heavy liquids like perfluorocarbon come in. These liquids have a higher density than water, allowing them to remain in the lower part of the eye and gently flatten the detached retina, making it easier for the surgeon to identify and repair tears.

After the retina is flattened and stabilized, the heavy liquid is gradually replaced with another fluid, gas, or silicone oil, depending on the case.

3. Silicone Oil Tamponade

In very complex cases, or when there is a high risk of re-detachment, the surgeon may inject silicone oil into the eye. Silicone oil is a clear, dense substance that helps keep the retina flattened and attached to the eye wall for a long period, giving it time to heal. A subsequent surgery is then required to remove the silicone oil.

Surgery for recurrent or complex retinal detachment, which may include these techniques, is a procedure that requires high expertise and extreme precision. The cost of complex/tractional/retinal detachment vitrectomy surgery in Egypt for 2026 is approximately an average of 50,000 EGP (approximate). These prices are approximate and depend on the complexity of the case.

4. Laser or Cryopexy Treatment

After the retina is flattened and reattached, laser or cryopexy may be used around the tear area to create strong adhesions between the retina and the eye wall, preventing new tears or future detachment. This procedure is known as Retinopexy.

Importance of Early Diagnosis and Follow-up

Prompt response to symptoms such as the sudden appearance of light flashes, a sudden increase in the number of floaters (flying flies), or the appearance of a dark curtain obscuring part of the field of vision, is crucial. These symptoms may be warning signs of a retinal tear or detachment, especially after eye trauma. Early diagnosis through precise examinations such as fundus examination, optical coherence tomography (OCT), and fluorescein angiography (FFA), can save vision.

After surgery, regular follow-up with the retinal surgeon is vital to ensure the success of the operation, early detection of any potential complications, and assessment of the extent of vision recovery. Follow-up may include periodic examinations, and possibly the need for additional treatment sessions such as intravitreal injections or laser.

Conclusion

Traumatic giant retinal detachment presents a significant medical and surgical challenge, but it is not insurmountable. Thanks to advances in retinal surgery techniques and the accumulated experience of specialized retinal surgeons like Dr. Mahmoud Hassan at Al-Mashreq Eye Center, these emergent cases can be handled effectively. Awareness of symptoms, prompt seeking of specialized medical help, and adherence to the treatment and follow-up plan are essential factors for saving vision and preventing complete retinal collapse.
