purpose:  to evaluate the significance of the presence of pigment granules in  the anterior  vitreous as a reliable indicator of retinal breaks in patients with acute symptomatic posterior vitreous detachment  (pvd) . methods: this cross sectional study included 209 phakic patients with acute symptomatic pvd. the patients underwent anterior vitreous examination and fundoscopy. patients with dia...

Introduction Understanding divertor detachment is essential to predicting the operation of future diverted tokamaks. The current plan for ITER operation assumes that the plasma is detached from the divertor, that f e be near the Greenwald limit [1] and that the main plasma is not diluted by impurities. However, we do not know whether these conditions can be achieved simultaneously. In this set ...

Newly Recognized Serous Macular Detachment in Retinal Vascular Disease Serous macular detachment has only recently been recognized to occur in a significant number of eyes with retinal vascular leakage, including diabetic macular edema,1,2 branch retinal vein occlusion,3–5 central retinal vein occlusion (CRVO),6 and hypotony maculopathy.7 These serous retinal detachments associated with retinal...

The only frequent extraocular abnormalities they found, in spite of fairly intense medical investigation, were a raised cerebrospinal fluid protein without pleocytosis and some patients with "rheumatic disorder". They reported seventeen cases, including one female. They drew attention to several previous papers reporting cases similar to their own. Stallard (I954) described six cases of "a pecu...

All RDs are accompanied by some loss of visual function but this will vary depending upon the type of detachment, its size, and retinal location, making it difficult to ascribe one set of symptoms to the condition (Box 71.3). Diagnosing RD is complex with many qualifications. Abnormal vision is the only reliable symptom of RD. But the types of abnormal vision are large and varied: light flashes...

with the aim of a determination of physical properties of date palm male flowers, as well as optimum flower detachment conditions, this study was carried out in two parts. in the first part of the study, the palm groves of khuzestan province were totally surveyed. “ghanami” cultivar was in the end selected to be studied as the superior cultivar in the region. drying up of the male flowers at 70...

The influence of process conditions (substrate loading rate and detachment force) on the structure of biofilms grown on basalt particles in a Biofilm Airlift Suspension (BAS) reactor was studied. The structure of the biofilms (density, surface shape, and thickness) and microbial characteristics (biomass yield) were investigated at substrate loading rates of 5, 10, 15, and 20 kg COD/m3. day with...
