Retinal Detachment & Holes
Retinal detachment is an emergency condition in which the retina—a critical layer of tissue at the back of the eye—pulls away from the underlying layer of blood vessels that supply it with oxygen and nutrients.
When the retina detaches, its cells are deprived of oxygen. The longer retinal detachment remains untreated, the higher the risk of permanent vision loss in the affected eye.
A retinal hole is a small break in the retina that can develop due to aging or other factors. While a hole alone may not always lead to detachment, it can create an opening for fluid to seep underneath the retina, increasing the risk of detachment over time. Detecting and treating retinal holes early can prevent more serious complications.
Fortunately, both retinal detachment and retinal holes often present with clear warning signs. Prompt diagnosis and treatment by an eye specialist (ophthalmologist) can help preserve vision.
Symptoms
Although retinal detachment itself is painless, symptoms usually appear before the retina fully detaches. Common symptoms include:
The sudden appearance of many floaters—small bits of debris in your field of vision that look like spots, hairs, or strings and seem to drift before your eyes
Sudden flashes of light in one or both eyes
A shadow or curtain descending over a portion of your visual field
When to See a Doctor
Seek immediate medical attention if you suddenly experience symptoms of retinal detachment, such as new floaters, flashes of light, or the sensation that a dark curtain has fallen across your visual field.
Retinal detachment is a serious condition that requires urgent medical attention. Recognizing the warning signs and seeking prompt care can make the difference between preserving and losing vision. If you notice any of the symptoms described, contact an ophthalmologist immediately.
