Retinal Detachment Flashcards
How does retinal detachment occur?
The seperation between neurosensory retina and RPE leads to fluid filling this space.
What are the risk factors of retinal detachment?
Ageing, Myopia (thinner retina), Trauma, Surgery
What are the 3 Types of Retinal Detachment?
- Rhegmatogeneous Retinal Detachment
- Tractional Retinal Detachment
- Exudative Retinal Detachment
What is Rhegmatous Retinal Detachment and what are the three main signs?
Its the most common. Occurs due to break or tear in retina.
Signs = Flashes & Floaters, curtain like peripheral VF defect
What is Tractional Retinal Detachment and what are main signs?
Occurs from pulling forces on retinal surface (when neovascularisation occurs i.e. in diabetes/vein occlusions)
Signs = Flashes, Slow progressing VF defect
Symptoms = Trauma, Healing
What is Exudative Retinal Detachment and what are the main signs?
Occurs due to exudation of fluid into the tissue plane.
Signs = Rapid VF loss, no flashes or floaters.
What are the 5 main symptoms of retinal detachment?
- Symptomatic or Asymptomatic
- Flashes
- Floaters (larger)
- Curtain like VF defect
- Gradual decrease in vision
What are the 8 main signs of retinal detachment?
- Possible Reduced Va
- Possible RAPD
- Possible mild uveitis
- Lowered or Raised IOP
- Elevated Retina
- Thin Retina
- Tobacco dust (schaffer’s sign)
- Retinal breaks
What are the two referrals and mangement for retinal detachment?
- If macula off for ≤ 3 days and/or the superior bullous close to macula = EMERGENCY (Same day)
- If macula on (or off for > 3 days) with superior temporal fluid far from macula = URGENT (1-7days)
What are the surgery choices for retinal detachment?
If simple RD = Cryo Buckle
If complex RD = Vitrectomy, Laser breaks, fill eye with air to flatten retina.
