M. -any communications have described the structure and relation of the vitreous to the ciliary body and retina."'-~>~ •''• Yet our knowledge of this region of the eye remains incomplete. For example, the intimate relation of these tissues in infancy and childhood and the changes which occur with increasing age are poorly understood. The gross effects of some diseases on these tissues are known...

BACKGROUND Ecthyma gangrenosum is an infective lesion of the skin and mucosal membranes. It is most commonly caused by Pseudomonas aeruginosa, and the most important risk factors are malignancy and neutropenia. However, it has rarely been reported in children who were previously healthy. Persistent hyperplastic primary vitreous has been described as the persistence of the fetal hyaloid vascular...

Optical coherence tomography is a non-contact imaging method of the anterior and posterior segments eye that based on laser scanning in spectral domain. This study presents diagnostic possibilities new generation Solix FullRange™ OCT&OCTA apparatus (Optovue) to examine meibomian glands, cornea, chamber, as well iridocorneal angles lens. In segment it allows for precise evaluation vitreous b...

purpose : to investigate the penetration of cefixime and ciprofloxacin to the rabbit eye on the basis of microbial inhibition of aqueous and vitreous humour after oral administration. methods : in this experimental study, 36 rabbits (72 eyes) were randomly divided into two groups group a consisted of 20 rabbits and group b 16 rabbits. each group was divided into four equal subgroups. the rabbit...

Lenses were removed from chick embryos at 4 days of incubation and the corneas were studied at various time intervals postoperatively through 17 days of incubation. Approximately 2 to 4 hours postoperatively a wave of mesenchymal tissue, presumably perilimbic in origin, moved in to cover the posterior surface of the cornea. This retrocorneal sheet of tissue grew in thickness and differentiated ...

A pharmacokinetic model of ocular drug delivery has been developed for describing the elimination and distribution of ocular drugs in the eye. The model, based on Fick's second law of diffusion, assumes a modified cylindrical eye with three pathways for drug transport across the surface of the eye: the anterior aqueous chamber, the posterior aqueous chamber and the retina/choroids/scleral membr...
