Overview
Retinal detachment is a serious eye emergency that occurs when the retina, the light-sensitive layer of tissue at the back of the eye, separates from its underlying supportive tissue. Without prompt treatment, retinal detachment can lead to permanent vision loss in the affected eye. The retina cannot function when these layers are detached, and unless the retina is reattached soon, permanent vision loss may result.
The condition affects approximately 1 in 10,000 people each year, with certain groups at higher risk. While retinal detachment can occur at any age, it's most common in people over 40 and affects men more frequently than women. The severity and speed of vision loss depend on the location and extent of the detachment - if the macula (central vision area) detaches, vision loss can be severe and rapid.
Understanding the warning signs of retinal detachment is crucial because early detection and treatment significantly improve the chances of preserving vision. The condition is painless, which can delay diagnosis, but specific visual symptoms serve as important warning signals. With modern surgical techniques, over 90% of retinal detachments can be successfully repaired, though visual outcomes vary depending on the severity and duration of detachment.

Types of Retinal Detachment
Understanding the three main types of retinal detachment helps determine appropriate treatment approaches.
| Type | Cause | Characteristics | Risk Groups |
|---|---|---|---|
| Rhegmatogenous | Retinal tear or hole | Most common (90%), fluid seeps under retina | Myopic, aging, eye trauma |
| Tractional | Scar tissue pulling | Retina pulled away by scar tissue | Advanced diabetes, eye injuries |
| Exudative | Fluid accumulation | No tears, fluid collects beneath retina | Inflammatory disorders, tumors |
Causes and Risk Factors
Retinal detachment can result from various causes, with certain factors significantly increasing risk.
Primary Causes
- Aging: Natural changes in vitreous gel, becoming more liquid and shrinking
- Retinal tears or holes: Allow fluid to seep underneath the retina
- Trauma: Direct eye injury causing immediate or delayed detachment
- Advanced diabetes: Proliferative diabetic retinopathy with scar tissue
- Inflammatory disorders: Severe eye inflammation causing fluid accumulation
Major Risk Factors
- Severe myopia (nearsightedness): Elongated eyeball increases risk
- Previous retinal detachment: 10% risk in the other eye
- Family history: Genetic predisposition to retinal problems
- Previous eye surgery: Especially complicated cataract surgery
- Eye injuries: Boxing, racquet sports, or occupational hazards
- Lattice degeneration: Thinning of peripheral retina
- Age over 50: Natural aging processes
Associated Conditions
- Posterior vitreous detachment (PVD)
- Retinoschisis
- Stickler syndrome
- Marfan syndrome
- Ehlers-Danlos syndrome
- Homocystinuria
High-Risk Activities
Certain activities may increase risk for those predisposed:
- Contact sports (boxing, martial arts)
- High-impact activities
- Bungee jumping or skydiving
- Heavy lifting with Valsalva maneuver
Diagnosis
Prompt and accurate diagnosis of retinal detachment is crucial for preserving vision. Eye care professionals use various examination techniques and imaging technologies.
Clinical Examination
- Visual acuity test: Measures clarity of vision in each eye
- Visual field test: Detects blind spots or shadows
- Dilated eye examination: Allows complete view of retina
- Slit lamp examination: Detailed view of eye structures
- Indirect ophthalmoscopy: Wide-angle view of retina
Diagnostic Tests
- Ultrasound imaging: Used when retina can't be directly viewed (due to bleeding or cataracts)
- Optical coherence tomography (OCT): Detailed cross-sectional images of retina
- Fundus photography: Documents retinal condition
- Fluorescein angiography: Evaluates blood flow in retina
- B-scan ultrasonography: Detects retinal detachment behind dense cataracts
Differential Diagnosis
Conditions that may mimic retinal detachment:
- Retinoschisis (splitting of retinal layers)
- Choroidal detachment
- Vitreous hemorrhage
- Severe posterior vitreous detachment
- Retinal pigment epithelium detachment
Treatment
Retinal detachment requires urgent surgical intervention. The choice of procedure depends on the type, location, and severity of detachment.

Frequently Asked Questions
Is retinal detachment painful?
No, retinal detachment itself is typically painless, which can be deceiving. The absence of pain often delays people from seeking treatment. The primary symptoms are visual changes such as floaters, flashes of light, and shadow or curtain effects in the visual field. Some people may experience mild discomfort or a feeling of pressure, but severe pain is not characteristic of retinal detachment. If you experience eye pain along with vision changes, it may indicate a different or additional eye problem that also requires immediate attention.
Can retinal detachment happen in both eyes at the same time?
Simultaneous bilateral retinal detachment is extremely rare, occurring in less than 2% of cases. However, having a detachment in one eye increases the risk of detachment in the other eye to about 10-15%. This risk is higher in people with predisposing factors like severe myopia, lattice degeneration, or genetic conditions. Your eye doctor will carefully monitor your unaffected eye and may recommend preventive treatment if areas of weakness are detected. Some patients benefit from prophylactic laser treatment to strengthen weak areas in the fellow eye.
How long can I wait before seeking treatment?
Retinal detachment is a medical emergency - you should seek treatment immediately, ideally within 24 hours of symptom onset. The sooner treatment begins, the better the chances of preserving vision. If the macula (central vision area) is still attached, urgent surgery within 24-48 hours can preserve central vision. Once the macula detaches, each day of delay can result in permanent vision loss. Even if symptoms appear on a weekend or holiday, seek emergency eye care immediately rather than waiting for regular office hours.
Will I be able to drive after retinal detachment surgery?
Driving restrictions after retinal detachment surgery vary depending on the procedure and recovery. Initially, you cannot drive due to dilating drops, gas bubbles blocking vision, and positioning requirements. Most patients need 2-8 weeks before driving, depending on visual recovery and whether both eyes have good vision. Your surgeon will clear you to drive only when your vision meets legal requirements and is stable. Some patients may need new glasses or have permanent blind spots that affect driving ability. Always follow your doctor's specific recommendations about when it's safe to resume driving.
Can I fly after retinal detachment surgery?
If you have a gas bubble in your eye after surgery, you absolutely cannot fly or travel to high altitudes until the gas completely absorbs. The reduced atmospheric pressure at altitude causes the gas to expand, which can cause severe eye pain and permanent vision loss. This restriction typically lasts 2-8 weeks depending on the type of gas used. Your surgeon will tell you when it's safe to fly. If you have silicone oil instead of gas, flying is generally safe. Always wear a medical alert bracelet indicating you have an eye gas bubble in case of emergency transport needs.
What are the chances of retinal detachment recurring?
The overall success rate for retinal detachment repair is high, with 85-95% of retinas remaining attached after initial surgery. However, 10-20% of cases may require additional procedures due to complications like proliferative vitreoretinopathy (PVR) or new tears. Risk factors for recurrence include severe myopia, multiple tears, giant retinal tears, and PVR development. Even after successful surgery, new tears can develop in other areas of the retina, so lifelong monitoring is important. Regular follow-up examinations help detect problems early when they're most treatable.
