The clinical features of pigmented lens striae were studied biomicroscopically in seven patients. The lenses of three of these, obtained by cataract surgery, were examined by electron microscopy to determine the structure of the striae. We concluded that the striae are not formed by remnants of tunica vasculosa lentis, as earlier workers believed, but consist of fine fibrils of zonular bundles ...

SALSA MLPA probemix P027 Uveal melanoma Page 1 of 7 SALSA MLPA probemix P027-C1 Uveal melanoma Lot C1-0814 & C1-0213 & C1-0211: A large number of probes have been replaced by other probes in the same chromosomal regions as compared to previous lots, and several reference probes have been replaced/included. Details are in Table 1. As a result, the version number has been changed to C1. In additi...

PURPOSE To identify electrophysiologically the functional types of sensory fibers innervating the iris and the ciliary body of the cat's eye. METHODS The uveal tract tract of cat's eye was excised and placed in a superfusion chamber. Recordings were made from single afferent units of ciliary nerve branches responding to mechanical stimulation of the iridal surface, the ciliary body, and the c...

PURPOSE To investigate the dynamics and distribution of toll-like receptor 4 (TLR4)-positive cells and resident tissue macrophages in the uvea during endotoxin-induced uveitis (EIU) in Wistar rats. METHODS Wistar rats (n=40) received a footpad injection of 200 microg of Vibrio cholera lipopolysaccharide (LPS), and the intensity of anterior segment inflammation was evaluated after the LPS inje...

Abstract Case report - Introduction Uveitis is characterised by inflammation of the uvea, which middle portion eye; anterior uvea includes iris and ciliary body, posterior known as choroid. There are multiple infections inflammatory diseases that could cause uveitis. The aetiology uveitis often very difficult to decipher; especially in absence typical extra-ocular symptoms. description We a cas...

Eye problems constitute 2% to 3% of all primary care and emergency department visits. Common eye conditions that can cause eye pain are conjunctivitis, corneal abrasion, and hordeolum, and some of the most serious eye conditions include acute angle-closure glaucoma, orbital cellulitis, and herpetic keratitis. The history should focus on vision changes, foreign body sensation, photophobia, and a...

Eye globe abnormalities can be readily detected on dedicated and non-dedicated CT and MR studies. A primary understanding of the globe anatomy is key to characterising both traumatic and non-traumatic globe abnormalities. The globe consists of three primary layers: the sclera (outer), uvea (middle), and retina (inner layer). The various pathological processes involving these layers are highligh...

The expected incidence of blindness among children under 5 years of age in Malawi is 34 cases per 100 000 children. Direct ocular infections were responsible for the blindness in 32% of the cases (bacterial infections 20% and measles 12%). The instillation of traditional medicine in these cases worsened the ocular condition and induced in all of the cases a "hopeless" situation of total melting...

Delivery of 2.1 microgram of cholera toxin, a specific, irreversible activator of adenylate cyclase, via the blood lowers IOP from 17.4 to 11.2 mm Hg in 81/2 hr. decreases net aqueous flow by about 50% in 8 hr, and doubles blood flow to the anterior uvea at 8 to 13 hr. Intravitreal injection of 0.26 microgram of cholera toxin lowered IOP from 15.0 to 9.6 mm Hg, but heat-inactivated toxin had no...
