The posterior chamber consists of small space directly posterior to the iris but anterior to the lens. The posterior chamber is part of the anterior segment [1] and should not be confused with the vitreous chamber (in the posterior segment). Posterior chamber is an important structure involved in production and circulation of aqueous humor ...
Pain in the eye(s) Redness of the eye(s) Blurred vision; Photophobia; Irregular pupil; Signs of anterior uveitis include dilated ciliary vessels, presence of cells and flare in the anterior chamber, and keratic precipitates ("KP") on the posterior surface of the cornea. In severe inflammation there may be evidence of a hypopyon. Old episodes of ...
The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body. It contains the ciliary muscle, vessels, and fibrous connective tissue. Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber. The aqueous humor ...
The retina is the innermost layer of the eye. The retina contains nerve cells responsible for sensing light and sending visual information to the brain. [6] The eye can also be divided into three chambers: Anterior chamber: (between the cornea and iris) Posterior chamber: (between the iris and lens) Vitreous chamber: (between the lens and ...
Some ophthalmologists specialize in the treatment and management of posterior segment disorders and diseases. [ 3 ] In some animals, the retina contains a reflective layer (the tapetum lucidum ) which increases the amount of light each photosensitive cell perceives, reflecting the light out of the eye, allowing the animal to see better under ...
UGH Plus and IPUGH (Incomplete Posterior UGH) are the variations of UGH syndrome. IPUGH is defined as bleeding into the posterior chamber with/ without glaucoma and no uveitis. [1] UGH Plus is defined as a UGH syndrome plus a vitreous hemorrhage and occurs more frequently with anterior chamber IOLs but can occur with any IOLs. [1]
However, if the eyes are asymmetrically affected, i.e. one eye's optic nerve is more damaged than the other, it will produce an important sign called an afferent pupillary defect. [citation needed] Defective light perception in one eye causes an asymmetrical pupillary constriction reflex called the afferent pupillary defect (APD). [citation needed]
They are attached by their periphery to three or four of the ridges of the orbiculus ciliaris, and are continuous with the layers of the choroid: their opposite extremities are free and rounded, and are directed toward the posterior chamber of the eyeball and circumference of the lens. In front, they are continuous with the periphery of the iris.
