WebSmall, peripheral effusions may be asymptomatic, with minimal to no shallowing of the anterior chamber. Large effusions may cause refractive changes from anterior displacement of the lens-iris diaphragm and resultant myopia, or they may cause significant reduction in visual acuity by encroachment into the visual axis. Pulmonary blebs are small subpleural thin-walled air-containing spaces, not larger than 1 or 2 cm in diameter (with the precise limit varying by source). Their walls are less than 1 mm thick. If they rupture, they allow air to escape into the pleural space resulting in a spontaneous pneumothorax . See more Blebs are a very common finding in otherwise normal individuals. They are often found in young patients. They are more common in thin … See more In the vast majority of cases, blebs remain asymptomatic. Occasionally they are thought to rupture resulting in a pneumothorax. See more Pulmonary blebs are not visible on chest x-rays, but may be seen on the lung windows of CTs. In patients who have had a pneumothorax … See more Blebs are thought to occur as a result of subpleural alveolar rupture, due to overload of the elastic fibers. Pulmonary bullae are, like blebs, cystic air spaces that have an imperceptible wall (less than 1 mm). The difference … See more

WebJan 9, 2024 · Based on our observations of the PDI sign, we propose that bullas and blebs may be caused by high pressure due to air trapping from a check-valve mechanism, which indicates peripheral airway stenosis. If so, bullas and blebs may be prevented by resolving peripheral airway abnormalities in the upper lobes. WebAll of the sutures were secured with episcleral bites peripheral to the actual bleb. The overall effect was that of a grid, with evenly placed pressure points, as seen in Figure 2, which has a slight modification. When we removed the sutures 1 week postoperatively, the IOPs remained in the range of 9 to 14 mm Hg on no drops. This outcome was ... old sears scroll saw

WebJan 23, 2015 · Severe bleb inflammation (severe congestion, presence of corkscrew vessels) can be managed using subconjunctival injection of 5-FU (5 mg in 0.1 mL) or MMC. The site of injection depends on surgeon preference but the trend now is to inject the antifibrotic adjacent to or into the bleb rather than away from the bleb.
