If you’ve recently noticed new floaters, flashes of light, or a curtain over part of your vision, it’s critical to seek care immediately. While most floaters are harmless, these symptoms may also be the first signs of a retinal tear or detachment—a medical emergency that could lead to permanent vision loss if untreated.
When to Call Immediately:
– Sudden new floaters (black/grey specs or squiggles)
– Flashes of light (camera flash, sparklers)
– Vision covered by a black curtain or shadow
– Sudden blurred or missing vision in one eye
If you experience these symptoms and we’re unavailable, please go to Rockyview General Hospital, where an on-call ophthalmologist can assess you.
What Causes Floaters & Flashes?
– Posterior Vitreous Detachment (PVD) – Often harmless but must be confirmed
– Retinal Tear or Detachment – Time-sensitive and may require laser or surgical repair
– Bleeding or Inflammation – Needs monitoring and may indicate deeper disease
– Migraine Auras (Flashes without floaters) – Generally harmless but sometimes confused for retinal causes
What to Expect During Your Emergency Eye Exam
Optos Ultra Widefield Retinal Imaging
This is a game changer for retinal detachment screening. It captures up to 82% of your retina in one shot—even without dilation—and allows us to spot tears, holes, or retinal thinning fast. Images are stored for tracking changes between visits.
Optical Coherence Tomography (OCT)
This 3D scan helps determine if the macula is still attached in cases of detachment. This detail is critical—if the macula is still “on,” surgery may save your central vision. If not, prognosis changes drastically.
Fundus Autofluorescence
This special filter detects metabolic stress or new damage in the retina that isn’t visible on standard color imaging. It’s excellent for ruling out or confirming subtler types of retinal trauma or disease.
Pupil Dilation (Critical in these cases)
Unlike most exams where dilation is optional, for new floaters or flashes, it is mandatory. Dilation gives us the best possible view of the peripheral retina, where detachments or tears usually occur.
Why Immediate Care Matters
A retinal detachment can cause permanent blindness within hours to days. The earlier we catch it, the better your outcome. We’re equipped to treat, monitor, or coordinate emergency referrals with surgeons if needed.
