Translations
photocoagulation
photocoagulation [fo″to-ko-ag″u-la´shun] condensation of protein material by the controlled use of an intense beam of light (e.g., argon laser); used especially in the treatment of retinal detachment and destruction of abnormal retinal vessels or intraocular tumor masses.pho·to·co·ag·u·la·tion (fō'tō-kō-ag'yū-lā'shŭn), A method by which a beam of electromagnetic energy is directed to a desired tissue under visual control; localized coagulation results from absorption of light energy and its conversion to heat or conversion of tissue to plasma (atoms stripped of electrons). [photo- + L. coagulo, pp. -atus, to curdle] photocoagulation (fō′tō-kō-ăg′yə-lā′shən)n. Surgical coagulation of tissue by means of intense light energy, such as a laser beam, performed to destroy abnormal tissues or to form adhesive scars, especially in ophthalmology.
pho′to·co·ag′u·late v.photocoagulation Ophthalmology The use of argon, or less commonly, xenon, lasers to focally burn the retina to ↓ neovascularization, microaneurysms, macular edema in Pts with various retinopathies Outcomes 50% ↓ in severe visual loss, compared to nontreated eyes. See Diabetic retinopathy. Cf Vitrectomy. pho·to·co·ag·u·la·tion (fō'tō-kō-ag'yū-lā'shŭn) A method by which a beam of electromagnetic energy is directed to a desired tissue under visual control; localized coagulation results from absorption of light energy and its conversion to heat or conversion of tissue to plasma (atoms stripped of electrons). [photo- + L. coagulo, pp. -atus, to curdle]photocoagulation Destruction of tissue by the heating effect of intense focused white light or by the use of a laser. It is widely used by ophthalmic surgeons to treat disorders of the RETINA, especially DIABETIC RETINOPATHY and areas of retinal degeneration that threaten to lead to retinal detachment.PhotocoagulationCancer treatment in which the tumor is destroyed by an intense beam of laser light.Mentioned in: Retinoblastomaphotocoagulation Process of changing blood and tissue from a fluid to a clotted state produced by the heat of an intense beam of light (e.g. laser), as used in the treatment or prophylactic treatment of retinal diseases (e.g. diabetic retinopathy, retinal detachments, retinal breaks, haemorrhages). See laser; age-related macular degeneration; retinal break; retinal detachment; diabetic retinopathy.photocoagulation
