PURPOSE Remodeling of the extracellular matrix occurs in the lamina cribrosa in progressed glaucomatous optic nerve damage including disc cupping. We examined immunohistochemical changes in the transforming growth factor (TGF)-beta and platelet-derived growth factor (PDGF) in the optic nerve head in an experimentally induced glaucoma model. METHODS We used 3 cynomolgus and 2 Japanese monkey e...
Sir William Mackenzie (I835) was the first to describe raised intraocular pressure (IOP) in glaucoma. Following the introduction of the ophthalmoscope, the presence of glaucomatous cupping was soon recognized (Jacobson, I853; Jaeger, I854; von Graefe, 1854; Weber, i 855; and others) and was confirmed histopathologically by Miuller (1856). Mackenzie (i854) described flattened and atrophic nerves...
Glaucoma is characterized by irreversible optic nerve degeneration and is the most frequent cause of irreversible blindness worldwide. Here, the International Glaucoma Genetics Consortium conducts a meta-analysis of genome-wide association studies of vertical cup-disc ratio (VCDR), an important disease-related optic nerve parameter. In 21,094 individuals of European ancestry and 6,784 individua...
Clinical measurements of a horizontal cup/disc ratio were obtained among a sample of 160 normal twin subjects by stereoscopic biomicroscopy. Measurements of horizontal cup/disc ratio were normally distributed and theere was no significant association with sex, laterally, race, or refractive error in the mid-range. However, there was a significant association between size of the cup/disc ratio a...
The simultaneous occurrence of both optic nerve head drusen and glaucoma may make it difficult to evaluate visual field defects and the appearance of the optic nerve head. We saw five patients with both conditions, of whom four had pigmentary glaucoma or pigmentary dispersion syndrome. Drusen do not preclude the development of cupping, and they make it difficult to interpret its significance. M...
BACKGROUND We aimed to investigate the effectiveness of two different forms of dry pulsatile cupping in patients with chronic low back pain (cLBP) compared to medication on demand only in a three-armed randomized trial. METHODS 110 cLBP patients were randomized to regular pulsatile cupping with 8 treatments plus paracetamol on demand (n = 37), minimal cupping with 8 treatments plus paracetamo...
Optic nerve-head examination is probably the most important step in the diagnosis of glaucoma and is also extremely important in monitoring patients with established glaucoma. There are several ways to clinically examine the optic nerve head, including direct ophthalmoscopy, indirect ophthalmoscopy, and slit lamp biomicroscopy with contact lenses (such as a Goldman lens), handheld lenses (such ...
Urkude J, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221549 Description Case 1: A posterior segment B-scan ultrasonography in a patient with typical iris coloboma and total cataract, showed well-defined excavated area in the inferior part just below the optic disc (red arrow) with the absence of retinochoroidal layer, suggestive of fundal coloboma (yellow arrow) (figure 1A). Involvement of ...
