Pattern of NT4 staining in normal and laser treated retinas. Haematoxylin and eosin and anti-NT4 stain. (A) Normal retina showing intense NT4 staining in inner and outer nuclear layers (arrows), 50× magnification. (B) One day post-laser showing reduced NT4 staining in ONL (arrow). This reduced staining is confined to the extent of laser injury, 50× magnification. (C) Six days post-laser showing atrophic ONL at the site of laser with only a few cells seen and reduced NT4 staining (arrows), 100× magnification.
