The main function of ocular blood flow is to supply sufficient oxygen and nutrients to the eye. Local blood vessels resistance regulates overall blood distribution to the eye and can vary rapidly over time depending on ocular need. Under normal conditions, the relation between blood flow and perfusion pressure in the eye is autoregulated. Basically, autoregulation is a capacity to maintain a re...

An ocular manifestation of a systemic disease is an ocular condition that directly or indirectly results from a pathologic process from another part of the body. Ocular manifestations can occur in various systemic diseases in pediatrics.

The aim of this study is to formulate a novel ophthalmic nanosuspension (ONS), an alternative carrier system to traditional colloidal carriers for controlled release (CR) of acyclovir (ACV). In the present study, ONS is employed to avoid some of major disadvantages of colloidal carriers systems such as instability in cul de sac and short half life by increasing efficiency of drug encapsulation ...

since alkaline substances can rapidly penetrate into the cornea and subsequently damage limbal stem cells, another source of stem cells may be necessary to reconstruct the ocular surface. omentum has some such characteristics like ability to regenerate tissue as well as anti-inflammatory capacity. presence of adult stem cells and pluripotent embryonic cell markers make it suitable in wound heal...
