•Sight threatening disease
•Ocular emergency
•Deep irregular vascular pattern of
hyperemia
Flashes & Floaters
Take a history to determine other causes of floaters e.g. vitreous bleed or
inflammation of the eye (cyclitis or posterior uveitis) and rarely asteroid hyalosis.
Examine the patient on the slit lamp for:
- Tobacco dust in anterior vitreous? (high mag / small slit – ant vitreous)
- Then using a 60D or similar lens through a dilated pupil look for Weis ring
(definite signs of posterior vitreous detachment)
