Consensus‐based recommendations for indications and procedures in retinal laser treatment of Telangiectatic capillaries (TelCaps) in vascular macular oedema: A Delphi study

Acta Ophthalmologica, Volume 103, Issue 7, Page e485-e495, November 2025.
Abstract Purpose The identification of telangiectatic capillaries (TelCaps) in chronic macular oedema (ME) resistant to conventional intravitreal injections (IVIs) has renewed interest in focal laser treatment. However, the indications and modalities of this laser treatment remain to be clarified.

Observations of Clouds and Radiation Over King George Island and Implications for the Southern Ocean and Antarctica

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract Clouds play an important role in the Southern Ocean and Antarctic surface energy balance via their radiative effects and in surface mass balance via precipitation formation. Here, we use measurements at Escudero Station (62.2°S, 58.97°W) on King George Island, north of the Antarctic Peninsula, to characterize clouds and their effects on the ...

Recent Advancements in the Treatment of Age‐Related Macular Degeneration

Med Research, Volume 1, Issue 2, Page 151-169, September 2025.
ABSTRACT Age‐related macular degeneration (AMD) is a prevalent cause of visual impairment and blindness among the elderly. AMD can be categorized into two subtypes: “wet” and “dry.” Current treatments for wet AMD mainly involve anti‐vascular endothelial growth factor (VEGF) drugs, and there are three U.S.

Causal Directions Matter: How Environmental Factors Drive Convective Cloud Detrainment Heights

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract This study investigates how environmental factors influence the level of maximum detrainment (LMD) in deep convective clouds. Through a novel application of the Linear Non‐Gaussian Acyclic Model (LiNGAM), we discover causal structures between environmental variables and LMD, observed at six tropical sites operated by the Atmospheric Radiation ...
