Outcomes and complications of sponges versus tires for scleral buckling in primary rhegmatogenous retinal detachment: The Manchester Buckle Study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare preoperative characteristics and postoperative anatomical and functional outcomes of scleral buckle surgery using sponges versus tires, as well as explant‐related complications and the frequency of explant removal. Methods This retrospective study included patients with primary rhegmatogenous retinal detachment (RRD) who ...

The Making of Delta Sunspots

The Astrophysical Journal
We explore what fraction of delta sunspots with a sharp polarity inversion line (PIL) in photospheric magnetograms are produced by a writhe kink in an emerging twisted flux rope.

Changes in choroidal and retinal thickness 6 months before and during 18 months of orthokeratology lens treatment in myopic children

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate changes in choroidal and retinal thickness before and during myopia control treatment with orthokeratology lenses (OKL) in myopic children. Methods This was a sub‐study of CONTROL and CONTROL2 studies. The present study was a 2‐year, prospective, single‐group interventional study consisting of a 6‐month pre‐treatment ...

Risk factors for the development of subretinal fluid in the fellow eyes of patients with chronic central serous chorioretinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess the risk of subretinal fluid (SRF) development in the fellow eye of chronic central serous chorioretinopathy (cCSC) patients with unilateral SRF at baseline. Methods Medical records of 334 presumed cCSC patients were retrospectively reviewed.

Indeterminancy and Sunspots with Constant Returns [PDF]

We show that indeterminacy can easily arise in multi-sector models that have constant variable returns to scale and very small market imperfections. This is in sharp contrast to models that require increasing returns to generate indeterminacy, and which ...

Automatic sunspots detection on SODISM solar images [PDF]

, 2017
YesThe surface of the sun often shows visible sunspots which are located in magnetically active regions of the Sun, and whose number is an indicator of the Sun’s magnetic activity. The detection and classification of sunspots are useful techniques in the

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Sunspots Temperature Measurements

, 2023
Sonce je nam najbližja zvezda. Na Soncu se v vidni svetlobi med povečano magnetno aktivnostjo pojavijo številne Sončeve pege, ki so posledica motenj v Sončevem magnetnem polju. V nalogi smo se osredotočili na merjenje temperature Sončevih peg. V ta namen

Observations key to understanding solar cycles: a review

Frontiers in Astronomy and Space Sciences
A paradigm shift is taking place in the conception of solar cycles. In the previous conception, the changing numbers of sunspots over intervals of 9–14 years have been regarded as the fundamental solar cycle although two average 11-year cycles were ...
