Ret On Web

 Retina is the light sensitive layer in the eye that lines the inside part of the eye and sends visual impulse through optic nerve to brain. Retina sometimes can get detached from  its position and loses its capacity to send visual impulses. There are different types of retinal detachment (RD). 1. Rhegmatogenous RD : Tear/Break in retina allows fluid to get under the retina and lifts it up. This is most commonly seen retinal detachment 2. Tractional RD : Scar tissue over retinal surface contracts and causes retina to seperate. 3. Exudative RD : Frequently caused by retinal inflammatory or noninflammatory disorder causing retina to detach. Risk factors for rhegmatogenous RD:  High myopia Peripheral retinal degenerations like lattice degeneration, snail tract degeneration Family history of RD Post cataract surgery Following eye injury Risk factor for tractional RD: Proliferative diabetic retinopathy Post vein occlusion Retinal vasculitis FEVR Seque...

  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 d...
