2. Sensation of a Dark Curtain or Shadow Moving Across Your Vision: A Retinal Detachment Emergency
Recognizing the “Curtain” or “Shadow” Symptom
Many patients describe seeing a dark curtain, shadow, or veil descending over part of their visual field. This is a medical emergency.
Why Is This a Critical Warning Sign?
This symptom often indicates retinal detachment or tear. The retina is no longer attached to the underlying tissue, which can cause permanent blindness if not treated immediately.
Associated Symptoms
- Flashes of light
- Sudden increase in floaters
- Sudden decrease in visual clarity
- Peripheral vision loss
Immediate Action
If you experience this symptom, seek emergency ophthalmologic care immediately. Delay can result in complete vision loss.
Treatment Options
- Laser therapy to secure the retina
- Cryopexy (freezing therapy)
- Surgical procedures like vitrectomy or scleral buckle
