Novel OCT Application and Optimized YAG Laser Enable Visualization and Treatment of Mid- to Posterior Vitreous
Abstract:
Vitrectomy is an effective treatment for visually disabling vitreous opacities (floaters) but carries significant surgical risk. Nd:YAG laser vitreolysis using newer technology has been shown safe and effective in treating symptomatic Weiss ring vitreous floaters. These Weiss rings, as well as amorphous opacities in the mid- to posterior vitreous, can be impossible to visualize or treat using conventional YAG lasers. In the cases presented here, undetected symptomatic amorphous type posterior vitreous floaters were confirmed with assistance of a novel optical coherence tomography application and successfully treated using a YAG laser optimized for vitreolysis. These cases suggest that with proper technology and technique, laser vitreolysis may be safer and more effective than previously recognized. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:806-811.].

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
