Update on Micropulse Transscleral Cyclophotocoagulation

Journal of Glaucoma, 2020
Micropulse transscleral cyclophotocoagulation is a promising and relatively new technique that uses repetitive micropulses of diode laser energy, delivered with the Cyclo G6 Glaucoma Laser System (Iridex Corporation), in an off-and-on cyclical manner.

Micropulsations and the plasmapause

Journal of Atmospheric and Terrestrial Physics, 1976
Abstract Based upon observations from a series of OGO satellites and ground measurements, the properties and structure of plasmapause-associated irregularities and the ring current are summarized in the following terms in relation to geomagnetic pulsations: 1. (1) spatial structure and maintenance; 2.

Theoretical simulation of micropulsations

Journal of Geophysical Research, 1967
The combined processes of cyclotron instability and quasilinear diffusion for low-energy protons are studied in some detail, and equations describing these processes are derived for a bounded plasma with reflecting walls. These equations are used by a computer to simulate micropulsation pulses (Pc 1).

Giant Micropulsations

Terrestrial Magnetism and Atmospheric Electricity, 1942
A magnetic storm of medium intensity for this Observatory started at about 07h 26m GMT, March 1, 1942. The ranges of the storm were: D, 38′.2; H, 224 gammas; Z, 205 gammas. Giant pulsations appeared on all three traces (D, H, and Z), at about 14h 30m GMT and continued for 3‐1/2 hours. These pulsations are unique in our experience at this Observatory.

On the correlation of meteors with micropulsations

Journal of Geophysical Research, 1963
Nighttime geomagnetic micropulsations were observed in the 1.5-cps frequency band down to a limiting sensitivity of 0.05 mγ. These results were compared with all-sky and localized radar meteor rates obtained at the same site to investigate the magnetic effects produced by meteors.

Subthreshold Diode Micropulse Laser: A Review

Seminars in Ophthalmology, 2016
The subthreshold diode micropulse laser is a form of non-damaging thermal laser therapy which has shown efficacy in multiple retinal conditions. The purpose of this article is to review the use of subthreshold diode micropulse laser as an emerging treatment modality for the treatment of retinal disease.

Micropulse Transscleral Cyclophotocoagulation in Keratoplasty Eyes

Cornea, 2019
Purpose: To assess the outcomes of micropulse transscleral cyclophotocoagulation for intraocular pressure (IOP) control in keratoplasty eyes. Methods: Outcomes of micropulse laser treatments of postkeratoplasty eyes were retrospectively reviewed.

Giant micropulsations at Abisko

Terrestrial Magnetism and Atmospheric Electricity, 1931
At the Geophysical Observatory of Abisko, Swedish Lapland, a set of Toepfer variometers has been in operation since midsummer 1921, with a break of one month only in October to November 1927, when more rigid mountings were made. The time‐scale has been 20 mm per hour and sensitivities of 5γ in eastward, 10γ in northward, and 8γ in vertical component ...

Dotted pearl micropulsations

Journal of Geophysical Research, 1968
Spectrograms of pearl (Pc 1) micropulsations show dotted rising tones. It is suggested here that the dot structure is due to interference between the two components of a double tone or ‘hook.’ The observed dot structure could be produced by a nonconvective cyclotron instability of protons of about 100-kev energy and 60° pitch angle.
