Paper Abstract

Retinal nerve fiber layer (NFL) damage can be induced by retinal laser photocoagulation. This type of thermal injury involves degeneration in both descending and ascending directions from the photic injury site. We have repeated early studies in evaluation of the acute phases of the injury process. Our findings indicate that the ascending or Wallerian portion of the NFL degeneration requires less time than the descending portion; an early neural debris channel occurs in close proximity to retinal vessels and appears to enter the optic disc in close proximity to the retinal vasculature. Angiography of the ascending debris sheath suggests possible capillary pattern modulation associated with this neural debris sheath. Retinal traction evident in with other acute injuries appears at 2 weeks and disappears after 8 weeks suggesting secondary control factors other than retinal hemorrhage in the development of retinal traction bands.
