Corneal blood staining after hyphaema.
Corneal blood staining has been described as a rare complication of contusion injury in which a hyphaema of relatively long duration and a raised intraocular pressure coexist. It is infrequent after penetrating injuries, in which the tension is usually low, and is occasionally found in association with haemorrhagic glaucoma, occlusion of the central retinal vein, and intraocular tumours (Berlin...
متن کاملBlinking Characteristics and Corneal Staining in Different Soft Lens Materials
Background Contact lens (CL) wear can cause changes in blinking and corneal staining. Aims and Objectives To determine the effects of CL materials (HEMA and SiHy) on spontaneous blink rate, blinking patterns and corneal staining after 2 months of wear. Methods Ninety subjects in 3 groups (control, HEMA and SiHy) were assessed at baseline and 2-months. Blink rate was recorded using a video camer...
متن کاملObjective assessment of corneal staining using digital image analysis.
PURPOSE To validate a new objective digital image analysis technique to evaluate corneal staining. METHODS One hundred photographs of corneal staining from various ocular surface diseases in 100 patients were quantified by a new strategy: a combination of the difference of Gaussians (DoG) edge detection for morphologic properties of corneal erosions and the red-green-blue (RGB) systems and hu...

متن کاملHow to measure and record blood pressure
What is blood pressure? Blood pressure is the force of blood against the walls of the arteries. Blood pressure is recorded as two numbers, the systolic pressure (the pressure when the heart beats) over the diastolic pressure (the pressure when the heart relaxes between beats). We record this with the systolic pressure first (on the top) and the diastolic pressure second (below). For example, if...
