PURPOSE Asteroid hyalosis is a disease of the vitreous, characterized by brilliant reflecting particles, termed asteroid bodies, which are surrounded by a tightly adhering network of fibrils. The composition and mode of formation of asteroid bodies is not yet understood in detail. The purpose of this study was to investigate the ultrastructure of asteroid bodies and to identify the intrinsic in...

Significant association of asteroid hyalitis with other ocular diseases has beeri disclaimed by clinical (Rutherford, I933) and pathological (Rodman, Johnson, and Zimmerman, I 961) observation. The literature on retinal separation is so voluminous that oversight is possible, but a search of the literature over go years has revealed only three references (D'Oench, I889; Bailey, I926; Krejci, I96...

Vitreous floaters are common. Most every ophthalmologist treating adults sees new and existing patients with a chief complaint of floaters in the office on a daily basis. Yet, treatment options for bothersome floaters have traditionally been quite limited. Robert Machemer introduced pars plana vitrectomy (PPV) in the early 1970s, and with the progressively decreasing gauge size, the idea of PPV...

Rabbits fed a diet rich in cholesterol developed hypercholesterolemia and atheromas in the cornea, sclera, iris, ciliary body, and choroid, and a few synchysis scintillans in the vitreous. The fellow eye of these rabbits, in which one nasal vortex vein was occluded, developed far more severe changes in all the above-mentioned eye tissues, especially over the sector of the eye drained by the occ...
