Barrage Laser

 Barrage Laser

     Barrage laser is the retinal laser which will be done around weak areas of retina like lattice degeneration or retinal holes or retinal breaks where laser will be given surrounding the lesion like a barrage( Fence) to make surrounding areas stronger adhesion and should not lead to any complications later.

    Barrage laser can be done with argon, diode or Double frequency Nd yag Laser with help through slip lamp delivery or indirect ophthalmoscope

Indications:

  - Lattice degeneration, snail tract degeneration: not all lattice degeneration requires barrage laser. 

- Retinal holes

- Retinal breaks with detachment

- subclinical retinal detachment to prevent further progression

- Choroidal coloboma with lifted intercalary membrane

Procedure:

    laser light will be given to retina like barrage surrounding the lesion completely without leaving spaces unlike in pan retinal photocoagulation for diabetic retinopathy. 

What are the aftereffects of using a barrage laser?

    NO long term after effects of barrage laser. However soon after procedure vision may be blurred for few hours  with mild pain. No precautions are required after barrage laser .
