Know the Common Retinal Disorders Including Detachment, Retinal Vascular Disorders and the Use of Lasers.Edit



Separation of the neuroretina from the underlying retinal pigment epithelium. An accumulation of subretinal fluid occurs and increases the separation. 


  • Rhegmatogenous: - meaning that a tear has occurred as a result of traction. Most common.
  • Tractional secondary to fibrotic eye disease
  • Exudative 
  • Traumatic
  • Post-operative

Myopic eyes are more likely to suffer a retinal detachment; the higher the myopia, the greater the risk. 

Signs and Symptoms

Classically remembered as the 4 Fs"

  • Floaters - many, acute onset, constant and described as "spider's web"
  • Flashes 
  • Field loss - acute and progressive
  • Falling acuity - sometimes described as "a curtain coming down over the vision"



From retinal detachment "ballooning" from 6-9 o' clock



- Scleral buckling to form an external tamponade

- Vitrectomy & gas/silicone oil injection to form an internal tamponade

- Cryotherapy or laser coagulation is used to secure the retina

The video below demonstrates all three techniques

Generally good if surgery is performed before macula detaches.

Post operative re-detachment occurs in 5 - 10 % of cases
