Development of angiopathy is the triggering for occurrence of destructive changes in the eyeball under the effect of opioid.

Sixty-ve patients awaiting vascular access operation were enrolled. Our study demonstrated a negative effect of the prolonged injection of opioid in the experiment on the state of microstructural organization of the eyeball vascular tunic. Vascular calcication of the coronary arteries or aorta is an independent risk factor for cardiovascular outcome, but clini-cal signicance of arterial micro-calcication (AMC) of vascu-lar access is unclear in hemodialysis (HD) patients. Histological and ultramicroscopic studies of the white rats' eyeball vascular tunic after six weeks of nalbuphine injections showed deep destructive changes in the structure of all parts of vascular tunic. The middle layer of the eye wall is called the vascular tunic, which in this region is the darkly pigmented choroid. During the next four weeks of the experiment, the pathological changes increase and are manifested by the swelling and polymorphonuclear infiltration of the iris, ciliary body, choroid and by deep destructive changes of eyeball hemomicrocirculatory bloodstream. vascular tunic or the vascular network within the developing vitreous. uva, grape), also called the uveal layer, uveal coat, uveal tract, or vascular tunic, is the pigmented middle of the three concentric layers that make up an eye.The name is possibly a reference to its almost black colour, wrinkled appearance and grape-like size and shape when stripped intact from a cadaveric eye. the tunica vasculosa lentis, which is part of the fetal vasculature system.

The first signs of microstructure disorder in all parts of vascular tunic of the eyeball are noticeable after two weeks of nalbuphine injection to the white rats. For the Pacific island, see Wallis Island. Specimens were studied and photographed with microscope magnification: ×600, ×1000. Floaters and blurred vision common during the early stages of diabetic retinopathy. Some of the most common signs of the disease are: Sudden painless loss of vision. For the histological study, microscopic sections of the eyeball were stained with Hematoxylin and Eosin, Heidenhain's Azan trichrome. The vascular tunic is comprised of three distinct regions, (1) the iris, (2) the ciliary body, and (3) the choroid. Depending on what type of disorder you have, retinal vascular diseases can be signaled by different symptoms. The research material included histological specimen and semi-thin sections of white rats' eyeball vascular tunic.

The study was carried out on 24 mature white male rats aged 3.0-4.5 months and 170-280 g weight. Contents 1 History and etymology 2 Structure 2.

This article deals with determination of changes in the structural organization of vascular tunic of the eyeball under the effect of opioid. uva, 'grape'), also called the uveal layer, uveal coat, uveal tract, vascular tunic or vascular layer is the pigmented middle of the three concentric layers that make up an eye.
