  • Abstract
  • Look Inside

We applied Q switched Nd-YAG laser to release vitreous traction to retinal breaks by severing the retinal flap. We treated 16 eyes: 13 eyes with primary rhegmatogenous retinal detachment and 3 eyes with tractional retinal breaks without retinal detachment. We aimed the Nd-YAG laser beam at the retinal flap overlying the breaks through Gold-mann three-mirror lens under maximum mydriasis. The number of laser bursts averaged 129 before the flap was completely severed. The laser treatment resulted in release of vitreous traction to the breaks in 14 eyes, 88 %. We performed pneumatic retinopexy in 9 eyes after successful release of vitreous traction by laser. Additional scleral buck-ling procedure was necessary in 4 of these eyes. Reattachment of the retina resulted in all the 9 eyes. Transient bleeding from the site of retinotomy occurred in 4 eyes. A new tear devel-oped later in one eye. The procedure promises to be of value. It may reduce the risk of redetachment by permanent release of vitreous traction to the retina.
