The purpose of this study is to compare the pain perception at laser treatment of peripheral retinal degenerations with green and infrared wavelengths.
Purpose: To compare the pain perception at laser treatment of peripheral retinal degenerations with green and infrared wavelengths.
Methods: Thirty patients (60 eyes) were enrolled in the study. Each patient had one eye treated with infrared laser (diode, 810nm) and the other eye treated with green laser (frequency-doubled solid state laser, diode-pumped, with 532-nm). The laser treatment was performed following a standardized protocol. Immediately after photocoagulation, the patient was asked to grading pain perception according an 11-point (i.e. 0-10) numerical rating scale (NRS) 2,3, accompanied by the instructions "Please rate your pain by indicating the number that best describes it". This NRS is represented as a straight line (10 cm in length). The numbers between 0 and 10 are spaced at regular intervals along the line, at either end of the line are two poles that are defined as the extreme limits of the response to be measure, with '0' meaning 'No pain' and '10' meaning 'Pain as bad as you can imagine'.

Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as in LASER THERAPY. These non-thermal effects are thought to be mediated by a photochemical reaction that alters CELL MEMBRANE PERMEABILITY, leading to increased mRNA synthesis and CELL PROLIFERATION. Low-level laser therapy has been used for a wide variety of conditions, but most frequently for wound healing and pain control.
A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
The use of photothermal effects of LASERS to coagulate, incise, vaporize, resect, dissect, or resurface tissue.
Fragmentation of CALCULI, notably urinary or biliary, by LASER.
