Retinal detachment

Retinal Detachment

in myopic p.t.

Symptoms

• Flashes, floaters, a curtain or shadow moving over the field of vision
• Peripheral and/or central visual loss

Retinal Detachment (RD)

Central → loss of vision RD in prephral → visual field defect RD 6/6

Types

1. Rhegmatogenous RD
2. Traction RD - DM
3. Exudative RD

Symptoms

• Flashes → Prodromal

• Floaters → Prodromal

  • Visual Field (VF) loss – curtain-like
  • Sudden, painless loss of vision

RD → Vitreous Hemorrhage

• Superior RD
  • الشبكية
  • العلوية
  • المنفصلة
• Interior Visual Field Defect

Risk Factors

• Peripheral Retinal Degenerations
  • e.g. lattice degeneration, retinal tufts…etc.
• High Myopia
• Aphakia
• Trauma
• History of RD history of RD of other eye or family

Retinal Detachment

• Retinal detachment denotes separation of the sensory retina from the underlying RPE

• There are three main types:

  • Rhegmatogenous
  • Traction
  • Exudative

---

Rhegmatogenous Retinal Detachment Formation

• Clinical manifestation:
  • Flashes of light, floaters, a curtain or shadow moving over the field of vision, peripheral and/or central visual loss.
  • Normal IOP, then low IOP
  • Elevation of the retina and a flap tear or break in the retina

Treatmentospe

without detachment argon laser

• Close the tears: by photocoagulation, condensation, electric coagulation
• Scleral buckling: retinopexy
• Vitrectomy
