Background
- Average age of onset ~55
Types
- Rhegmatogenous (rhegma means "tear")
- As vitreous separates from retina the traction creates a hole in retina
- Fluid goes through the hole and peels the retina off like wallpaper
- As vitreous separates from retina the traction creates a hole in retina
- Exudative
- Fluid accumulates beneath the retina without a retinal tear
- Associated w/ neoplasm, inflammatory conditions, hypertension, preeclampsia
- Tractional
- Acquired fibrocellular bands in the vitrous contract and detach the retina
- Associated w/ DM, sickle cell, trauma
- Distinguish between mac-off and mac-on
Clinical Features
- Abrupt onset of new "floaters" or flashes of light
- Vitreous tugs on the retina before separation
- Visual acuity loss (filmy, cloudy, or curtain-like) or visual field loss
- May be mild or dramatic
Differential Diagnosis
Diagnosis
- Examination
- Visual acuity and visual fields
- Fundoscopic exam with dilation
- Ultrasound
Treatment
- Urgent ophtho referral within 24hr
- In macular off retinal detachment, visual acute is significantly decreased if reattachment does not occur within 6 days. [1]
