Retinal Detachment

Definition:

Retina is the innermost layer of the eye which is responsible for image formation, when this retina is separated from the outer layers of the eye, it results in retinal detachment.

Risk factors:

  • Family history.
  • Preterm babies.
  • People with high minus power.
  • Birth defects in the retina.
  • Patients with holes/tears in the retina.
  • Any eye injury.
  • Tumours in the inner layer of the eye.
  • It can occur following any inflammation or infection in the eye.

Symptoms:

  • Sudden loss of vision.
  • Appearance of flashes/ floaters in front of the eye.
  • Sudden appearance of numerous black spots.

Diagnostic tools:

  • Ophthalmoscopy (Indirect with +20D lens) which is helpful in diagnosing retinal holes and tears.
  • Ultrasound both A and B scan.

Treatment Options:

  • Small tears and holes can be sealed using Cryotheraphy where cold laser seals the margins of the holes/tears in order to prevent further damage.
  • Laser photocoagulation.
  • Surgery:
    • To drain the fuild accumulated behind the retina (sub retinal fluid).
    • Scleral buckling and Vitrectomy to reattach the detached retina. In this they will take out the fluid in the back of the eye(vitreous humour) and then reattach the retina. Generally gas/ silicon oil is used temporarily to support the reattached retina.
    • Aurolab manufactures Aurooctane and Aurosil for retinal surgeries.
