Some authors suggest the removal of any glial tissue overlying(or adjacent to) the optic pit. One study looked at nine patients undergoing PPV [pars plana vitrectomy], PVD [posterior vitreous detachment] induction, laser photocoagulation and gas tamponade. Serous maculopathy resolved in six out of six patients in which the glial tissue surrounding the optic pit was removed.... Though glial tissue peeling has proven beneficial in a limited group of studies, precaution must be taken when performing this procedure due to the glial tissue's close proximity to the optic nerve.  2, record 1, English, - glial%20tissue%20peeling

Vitrectomy is a surgical procedure undertaken by a specialist where the vitreous humor gel that fills the eye cavity is removed to provide better access to the retina. This allows for a variety of repairs, including the removal of scar tissue, laser repair of retinal detachments and treatment of macular holes. Once surgery is complete, saline, a gas bubble or silicone oil may be injected into the vitreous gel to help hold the retina in position.  3, record 2, English, - vitrectomy

Results are presented for laser-induced breakdown spectroscopy(LIBS) as a method for measuring salt concentrations in sea water aerosol droplets. An excimer laser, operating at high pulse energy with KrF gas produces laser-induced breakdown plasmas in an aerosol spray. Emission lines of Na and H are monitored with an optical multi-channel analyzer to characterize the plasma spatially and temporally.  1, record 33, English, - laser%2Dinduced%20breakdown%20spectroscopy

Le faisceau est focalisé sur une ampoule contenant le liquide (ce qui permet de s'affranchir des problèmes d'électrodes); le claquage est détecté par l'apparition d'une émission lumineuse. Les champs de claquage optique (laser induced breakdown) dépendent fortement de la structure moléculaire.  3, record 33, French, - spectroscopie%20par%20claquage%20induit%20par%20%C3%A9clair%20laser

Optoacoustic detector. Light which is absorbed by a molecule is generally reradiated from the molecule in the form of heat. If a laser, at an absorbing wavelength of a gas of interest, is passed through a closed cell, the temperature of the entire gas in the cell will rise and thus the pressure of the gas in the cell will rise. If the laser is turned on and off at a frequency of 100-20000 Hz, the resulting pressure rises and drops can be picked up as a signal by sensitive microphones. This somewhat odd combination of optics and acoustics turns out to have several advantages over systems which measure the absorption directly. The absorption will be quite small and thus the change in intensity of the laser beam is nearly impossible to detect. Because pressure in the cell rises more quickly for small length cells, this effect exactly cancels out gains in overall absorption by making the cell longer. Thus, a small optoacoustic cell will accomplish the same as a larger cell making its size a great asset.... The device is being tested as a sniffer for bomb vapours and for ambient air analyses.  1, record 40, English, - optoacoustic%20detector
