Retinal detachment occurs when the light-sensitive layer at the back of the eye moves away from the tissue that normally supports it. It is usually painless, but it may cause sudden floaters, flashes of light, blurred vision, or a curtain-like shadow across part of the visual field.
Prompt assessment is important because retinal separation may gradually affect a larger area of the retina and reduce vision. According to trusted medical references, early examination and appropriate treatment can help protect as much vision as possible.
If these symptoms resemble what you are experiencing, seek urgent eye assessment rather than waiting for them to improve. You can also contact Magrabi’s team on WhatsApp to ask which retina service or UAE branch is appropriate.
The retina is a thin layer of nerve tissue lining the back of the eye. It receives light and converts it into signals that travel to the brain, allowing a person to see.
Retinal separation develops when part of this layer separates from its normal position. Once separated, the affected retinal cells may not receive enough oxygen and nutrients, which can interfere with vision.
The condition may begin with a small retinal tear or retinal hole. Fluid may then pass through the retinal break and collect underneath the retina, causing part or all of it to detach.
A partial retinal detachment means that only part of the retina has separated. It still requires urgent assessment because the detached area may expand and eventually involve the central retina.
There are three main types of retinal separation. Each develops through a different process and may require a different treatment approach.
Type | What happens? | Common associations |
Rhegmatogenous retinal detachment | A retinal tear, hole in the retina, or retinal break allows fluid to collect underneath it. | Age-related vitreous changes, severe myopia, eye surgery, or eye injury. |
Tractional retinal detachment | Scar tissue pulls the retina away from the back of the eye. | Advanced diabetic retinopathy and other conditions that cause retinal scarring. |
Exudative retinal detachment | Fluid collects beneath the retina without a retinal tear or hole. | Inflammation, abnormal blood vessels, tumours, or other retinal conditions. |
Rhegmatogenous detachment is the most common type. Tractional and exudative detachments require treatment of the underlying cause as well as management of the detached retina.
A common cause is a change in the vitreous, the clear gel filling the centre of the eye. As people age, this gel may shrink and move away from the retina.
In most people, this separation happens without complications. In some cases, however, the vitreous pulls strongly enough to cause a torn retina or retinal break. Fluid can then move through the tear and lift the retina from its normal position.
Factors that may increase the risk include:
Increasing age.
Severe nearsightedness or high myopia.
A previous retinal tear or detachment in either eye.
A family history of detached retina.
Previous cataract surgery or another eye operation.
A serious eye injury.
Weak or thin areas in the peripheral retina.
Lattice degeneration.
Advanced diabetic retinopathy.
Inflammation or other diseases affecting the retina.
Having one risk factor does not mean that retinal separation will occur. The UAE Ministry of Health and Prevention recommend discussing individual risk with an ophthalmologist, especially after previous eye surgery, trauma, or retinal problems.
Retinal separation symptoms often appear suddenly. The condition usually does not cause pain, so visual changes should not be ignored simply because the eye feels comfortable.
Possible detached retina symptoms include:
A sudden increase in floaters, which may look like dots, lines, threads, or cobwebs.
Repeated flashes of light, especially at the side of the vision.
A dark curtain or shadow moving across the visual field.
Loss of peripheral vision.
Sudden blurred or reduced vision.
A missing area in the visual field.
Difficulty seeing details if the central retina becomes involved.
New floaters do not always mean there is a retinal tear or detachment. However, a sudden shower of floaters, especially when accompanied by flashes or a curtain shadow, requires urgent eye assessment.
To understand the available examinations and treatment options, visit Magrabi UAE’s Vitreo-Retina Care service page. It explains the retina services, imaging, laser procedures, and surgical care available according to each patient’s diagnosis.
Diagnosis begins with questions about when the symptoms started, how quickly they changed, and whether there is a history of eye surgery, injury, diabetes, severe myopia, or retinal disease.
The examination may include:
Visual acuity testing: Measures how clearly each eye can see.
Dilated retinal examination: Eye drops widen the pupil so the ophthalmologist can examine the retina, vitreous, and peripheral retinal areas.
Indirect ophthalmoscopy or slit-lamp examination: Helps identify a retinal hole, retinal tear, bleeding, or detached area.
Eye ultrasound: May be needed if bleeding, cataract, or another opacity prevents the doctor from seeing the retina clearly.
Optical coherence tomography: May help assess the macula and confirm whether the central retina is involved.
Examination of both eyes: The other eye may also be checked for weak areas, tears, or risk factors.
A normal first examination does not always rule out a delayed retinal tear. The doctor may recommend another examination if symptoms continue, change, or return.
The effect on retinal separation vision depends on the location, size, duration, and cause of the detached area. Peripheral detachment may first cause a shadow or loss of side vision.
If the detachment reaches the macula, the central part of the retina used for reading, recognising faces, and seeing fine details, central vision may become blurred or significantly reduced.
Surgery aims to reattach the retina and prevent further loss of sight. The amount of vision that returns varies between patients and depends partly on whether the macula was detached and how long the retina remained separated.
Mayo Clinic explains that anatomical repair and visual recovery are not exactly the same. The retina may be successfully returned to its position, while visual improvement continues gradually over weeks or months.
Treatment depends on whether the patient has only a retinal tear or retinal hole, a partial retinal separation, or a more extensive detached retina. The location of the break, involvement of the macula, presence of scar tissue, and overall eye condition also influence the treatment plan.
Emergency retina treatment may involve laser, freezing treatment, gas injection, scleral buckle surgery, vitrectomy, or a combination of procedures. The ophthalmologist selects the method after examining the retina.
Laser photocoagulation may be used when a retinal tear or hole is found before a significant detachment develops. The laser creates small areas of scarring around the retinal break, helping attach the surrounding retina to the eye wall.
This retinal tear repair is intended to reduce the risk of fluid passing through the break. Laser treatment for a retinal tear is generally performed through the pupil, but suitability depends on the tear’s location and condition.
Cryopexy uses a controlled freezing probe on the outside of the eye over the location of the retinal break. The treatment produces a scar that helps secure the retina to the underlying tissue.
Cryopexy may be considered when the tear cannot be treated easily with laser or when the ophthalmologist believes freezing is more appropriate. Local anaesthesia is commonly used to numb the treatment area.
Partial retinal separation treatment is based on the size and location of the detached area, the number of retinal breaks, and whether the macula remains attached. A small detachment may still need a surgical procedure rather than laser treatment alone.
The doctor may recommend pneumatic retinopexy, scleral buckle surgery, vitrectomy, or a combined approach. The term “partial” should not be interpreted as meaning that treatment can safely be delayed.
During pneumatic retinopexy, the surgeon places a gas bubble inside the eye. The bubble presses the detached retina back against the eye wall while laser photocoagulation or cryopexy seals the retinal tear.
The patient may need to keep the head in a specific position so the bubble remains against the affected area. This procedure is suitable only for selected retinal tears and detachments.
A scleral buckle is a small flexible band placed around part or all of the outside of the eye. It gently pushes the eye wall closer to the detached retina and reduces the pulling force around the retinal break.
The buckle usually remains in place permanently unless the surgeon has a medical reason to remove it. Laser or cryopexy may be performed during the same procedure to close the tear.
Vitrectomy for retinal separation involves removing the vitreous gel that is pulling on the retina. The surgeon can then flatten the retina, treat retinal tears with laser, and place a gas bubble or silicone oil inside the eye to support healing.
Vitrectomy may be needed when the detachment is extensive, when scar tissue is present, when bleeding blocks the surgeon’s view, or when the location of the tear makes another technique less suitable.
Some patients require both vitrectomy and scleral buckle surgery. The surgeon explains the proposed procedure, expected recovery, and possible risks before treatment.
Retinal separation surgery cost varies according to several factors, including the type of surgery required, the complexity and extent of the detachment, the number and location of retinal tears, and whether the macula is involved. Additional elements such as the need for advanced imaging, the type of anaesthesia used, hospital facilities, surgical equipment, and medical supplies can also influence the overall cost.
The cost may also differ between procedures such as pneumatic retinopexy, scleral buckle surgery, vitrectomy, or a combination of techniques, depending on what is most suitable for the patient’s condition. In some cases, more than one procedure may be needed to achieve the best outcome, which can further affect the total cost. A reliable estimate can only be provided after a detailed retina examination, discussion of the treatment plan, and confirmation of insurance coverage or any required approvals.
Vision is often blurred immediately after retinal separation surgery. Improvement may be gradual, and the final visual result depends on the original retinal damage and whether the macula was affected.
Postoperative instructions may include:
Using prescribed eye drops exactly as directed.
Wearing an eye shield for the recommended period.
Avoiding rubbing or pressing on the eye.
Attending all follow-up appointments.
Maintaining a specific head position if a gas bubble was used.
Avoiding strenuous activities until the surgeon confirms they are safe.
Reporting increasing pain, redness, discharge, or worsening vision.
Patients with a gas bubble must not fly or travel to a high altitude until the surgeon confirms that the bubble has fully disappeared. Changes in air pressure can cause the bubble to expand and dangerously increase pressure inside the eye.
Not every retinal separation can be prevented because some cases result from natural age-related changes inside the eye. However, several steps may reduce risk or support earlier detection.
Magrabi doctors recommend:
Wearing protective eyewear during work, sport, or activities with a risk of eye injury.
Attending regular dilated eye examinations when severe myopia or retinal weakness is present.
Following the recommended retinal screening schedule for diabetes.
Managing blood sugar and blood pressure with the treating medical team.
Attending follow-up visits after eye surgery or retinal treatment.
Seeking immediate assessment for new floaters, flashes, shadows, or sudden vision changes.
Informing the ophthalmologist about a family history of retinal detachment.
There are no eye drops, supplements, or home exercises that can reattach a detached retina. Treatment must be selected by a qualified ophthalmologist after examining the eye.
Retinal separation is considered an eye emergency. Seek urgent medical assessment if you notice sudden floaters, flashes of light, loss of peripheral vision, a curtain-like shadow, or an unexplained sudden reduction in vision.
Do not wait for pain to appear. A retinal tear or detachment may be painless, and delaying examination may allow a larger part of the retina to separate.
The Department of Health Abu Dhabi emphasises that retina emergency symptoms should be evaluated as soon as possible, even if they affect only one eye or seem mild at first. Patients with recent eye trauma, previous retinal surgery, severe myopia, or diabetes may require particularly prompt evaluation.
Retinal detachment is a painless but urgent condition that may cause sudden floaters, flashes, peripheral vision loss, or a curtain-like shadow. Treatment depends on whether there is a retinal tear, partial detachment, or more extensive separation. Laser, cryopexy, pneumatic retinopexy, scleral buckle surgery, and vitrectomy may be considered. Prompt examination by a retina specialist offers the best opportunity to protect the remaining vision.
