Micropulse diode laser trabeculoplasty in Nigerian patients

Clinical Ophthalmology, 2015
The term micropulse laser trabeculoplasty suggests that only a fraction of the laser power is applied to the trabeculum to effect pressure lowering. It has not yet been exclusively used in Negroes, and we wish to report on our experience in Nigerian patients.The study design is a retrospective chart review of our patients at the Rachel Eye Center in ...

The Potential Role of hCG in the Development of Central Serous Chorioretinopathy Following In Vitro Fertilization

Case Reports in Ophthalmological Medicine, Volume 2026, Issue 1, 2026.
Background and Aims Central serous chorioretinopathy (CSCR) has been associated with fluctuations in endogenous and exogenous steroid hormones. This report describes a woman who developed unilateral CSCR following in vitro fertilization (IVF) treatment shortly after receiving human chorionic gonadotropin (hCG).

Performance of a MOPA laser system for photocathode research [PDF]

, 1993
A Nd:YLF laser system with frequency doubled output is described. Several aspects concerning energy and stability of the pulses will be discussed. The system consists of a CW mode locked Nd:YLF oscillator and two double pass amplifiers having a total ...

Lidar‐Based Observations of Pollen Above a Mixed Hardwood Forest in the United States

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract We present lidar (LIght Detection And Ranging) and particle measurements from a mixed hardwood forest in northern Michigan over a 74‐day period in April–July 2016, capturing the peak spring tree pollen emissions season. Mini Micropulse Lidar (MPL) observations of the normalized ratio backscatter and depolarization ratios show pollen plumes ...

Intermediary inflammatory reaction after micropulse cyclophotocoagulation diode therapy: a case report

Journal of Medical Case Reports, 2022
Introduction Of the many types of laser cyclophotocoagulation procedures, micropulse cyclophotocoagulation diode is praised as a noninvasive, safe, and effective procedure with few complications. In this case report, we describe a rare complication that,

Calculation of coherent emissions and gain from a prebunched free electron laser [PDF]

, 1995
This report advances a theoretical model for the single pass growth of coherent radiation in a prebunched FEL system. The FEL system includes a radio frequency linear accelerator (fr linac) as the injector, a resonator cavity with a wiggler magnet, and ...

Subthreshold micropulse diode laser treatment in diabetic macular oedema [PDF]

British Journal of Ophthalmology, 2004
Enlargement of laser scars after retinal argon laser photocoagulation can give rise to deterioration in visual acuity. Subthreshold micropulse diode laser may decrease this risk. The aim of this study was to compare the effectiveness of subthreshold micropulse diode laser (810 nm) and conventional argon laser (514 nm) photocoagulation for the treatment

Diurnal Cycle and Seasonality of Cirrus Clouds Over the Amazon From a Seven‐Year Ground‐Based Lidar Record

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 21, 16 November 2025.
Abstract Cirrus clouds strongly influence Earth's radiation balance, yet their optical properties and formation pathways add uncertainty to climate models. Satellites offer a global view of cirrus but have key limitations: passive sensors struggle to detect thin layers, and active instruments in polar orbits miss the diurnal cycle. Long‐term records of
