opacification การใช้

• Some early corneal inlay recipients experienced complications, such as corneal opacification, thinning and melting.
• Bilateral corneal opacification started in the second year of life and led to severe visual impairment.
• Fish-eye disease is less severe and most commonly presents with impaired vision due to corneal opacification.
• This technique is used in cases of anterior corneal opacifications, scars, and ectatic diseases such as keratoconus.
• As the situation worsens, there is corneal opacification, where the cornea becomes opaque, and band keratopathy.
• A drop of a corrosive may cause blindness within 2 10 seconds through opacification or direct destruction of the cornea.
• Fish-eye disease is characterized by abnormalities like visual impairment, plaques of fatty material, and dense opacification.
• As a result, the concentration of the absorbing or scattering particles in the glaze could determine the degree of opacification.
• The response may result in the destruction of the corneal stroma, resulting in loss of vision due to opacification of the cornea.
• Corneal opacification occurred in both transgenic lines early in development due to greatly increased expression of perlecan, fibronectin and thrombospondin-1 in the corneal mesenchyme.
• Similarly, the closer the particle size to the light wavelength ( 100-1000 nm for visible light ) and the more irregular the surface, the larger the degree of opacification.
• The design feature is intended to reduce Posterior Capsular Opacification ( PCO ) by creating an insurmountable physical barrier to cell migration from the haptic surface onto the optic surface of the lens.
• Posterior capsular opacification is common and occurs following up to one in four operations, but these rates are decreasing following the introduction of modern intraocular lenses together with a better understanding of the causes.
• -- > It manifests as severe corneal opacification or clouding, sometimes congenital, in the form of a ground glass, milky corneal tissue, and moon crater-like changes of corneal endothelium.
• Blunting of the lateral costophrenic angle usually requires about 175 mL but may take as much as 500 mL . Larger pleural effusions opacify portions of the hemithorax and may cause mediastinal shift; effusions > 4 L may cause complete opacification of the hemithorax and mediastinal shift to the contralateral side.
• Within twelve hours, it is essential to diagnose or exclude any source of infection that would require emergent source control, such as necrotizing soft tissue infection, infection causing chest x-ray consistent with pneumonia ( with focal opacification ), or petechiae, purpura, or purpura fulminans may be evident of infection.
• Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called'posterior lens capsule opacification '.
