Patient Education
Retinal Detachment
A retinal detachment occurs when the retina — the light-sensing layer at the back of the eye — pulls away from its normal position. Without prompt treatment, it can cause permanent vision loss.
Typical Symptoms
- A sudden increase in floaters (spots, webs, or strings in vision)
- Flashes of light, especially in peripheral vision
- A dark curtain, shadow, or veil drifting across your vision
- Blurry vision
- Reduced peripheral (side) vision
How It's Diagnosed
Dilated Eye Exam
Your doctor examines the entire retina through a dilated pupil using specialized lenses and light to identify tears, holes, or detachment.
Ultrasound
If the retina cannot be seen clearly (due to bleeding), ultrasound provides an image of the retina's position inside the eye.
OCT
Used to assess the extent of fluid accumulation and to evaluate the macula — the central retina critical for sharp vision.
How It Affects Vision
The impact depends on whether the macula (center of the retina) is involved. If the detachment has not reached the macula, central vision is often preserved and surgical outcomes are excellent. Once the macula detaches, central vision can be severely affected, and recovery after surgery — while possible — may be incomplete.
Treatment Options
Pneumatic Retinopexy
A gas bubble is injected into the eye to push the retina back into place. Laser or freezing treatment seals the tear. Requires specific head positioning for several days.
Scleral Buckle
A flexible silicone band is placed around the outside of the eye to gently push the wall of the eye toward the detached retina.
Vitrectomy
The most common surgery for complex detachments. The vitreous gel is removed, the retina is repositioned, and a gas or oil bubble holds it in place while it heals.
When to Seek Urgent Care
A retinal detachment is an ocular emergency. If you experience a sudden curtain or shadow in your vision, a dramatic increase in floaters, or loss of peripheral vision — call us immediately or go to the nearest emergency room. Time is critical. Surgery performed before the macula detaches gives the best visual outcome.
