When to seek urgent advice
New flashes or floaters, a sudden increase in symptoms, or symptoms after an eye injury or operation require an urgent retinal examination. A dark curtain or shadow, missing side vision, or sudden loss or worsening of vision requires emergency assessment. Do not wait for a routine appointment.
What is posterior vitreous detachment?
The vitreous is the clear gel inside the eye. As it changes with age, it can separate from the light-sensitive retina at the back of the eye. This is a posterior vitreous detachment (PVD). The separating gel can sometimes cause a retinal tear.
What might I notice?
Floaters may look like dots, threads or cobwebs that drift when the eye moves. Flashes are often brief and off to the side. A tear and an uncomplicated PVD can cause similar symptoms.
Your retinal examination
Mr Rabie checks the retina carefully through a dilated pupil, including its far edges. A scan or ultrasound may be used when helpful. A repeat examination may be advised depending on your symptoms and the findings.
If floaters persist
Flashes often settle and floaters usually become less noticeable over weeks or months. Vitrectomy is reserved for severe, persistent floaters that substantially interfere with daily life, following a discussion of likely benefit and surgical risk.
