Designing stem cell niches for differentiation and self-renewal [PDF]

, 2018
Mesenchymal stem cells, characterized by their ability to differentiate into skeletal tissues and self-renew, hold great promise for both regenerative medicine and novel therapeutic discovery. However, their regenerative capacity is retained only when in

Topical rosiglitazone is an effective anti-scarring agent in the cornea [PDF]

, 2013
Corneal scarring remains a major cause of blindness world-wide, with limited treatment options, all of which have side-effects. Here, we tested the hypothesis that topical application of Rosiglitazone, a Thiazolidinedione and ligand of peroxisome ...

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 ...

Repeatability of keratometry depending on tear film osmolarity

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the repeatability of keratometry and astigmatism measurements of patients depending on the tear film osmolarity using three different devices. Methods In this study, 97 eyes of 97 patients with a mean age of 64.92 ± 12.07 years received three repeated measurements with the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany),

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Corneal Biomechanics in Ectatic Diseases: Refractive Surgery Implications. [PDF]

, 2017
BACKGROUND: Ectasia development occurs due to a chronic corneal biomechanical decompensation or weakness, resulting in stromal thinning and corneal protrusion. This leads to corneal steepening, increase in astigmatism, and irregularity.

Patient‐reported outcomes and visual function after four refractive strategies in cataract surgery: A randomized controlled trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate patient‐reported outcome measures (PROMs) and visual function across four groups of public cataract patients: emmetropia, mini‐monovision, monovision with partial‐range of field (RoF) narrow intraocular lenses (IOLs) and patients implanted with partial‐RoF extended IOLs.
