Foundation Models in Diagnosis of Ophthalmic Diseases: Construction and Application

Eye &ENT Research, EarlyView.
ABSTRACT Artificial intelligence holds promise for addressing the uneven distribution of medical resources across different regions. Compared with convolutional neural network models, foundation models offer significant advantages: on one hand, their pre‐training does not rely on massive labeled data; on the other hand, they possess the capability to ...

The Effect of Microgravity on Lower Eyelid Position in Astronauts

Eye &ENT Research, EarlyView.
ABSTRACT Background Specific facial changes are known to occur in microgravity. A higher lower eyelid position has been observed during short‐term microgravity but has not been analyzed in astronauts during spaceflight. Purpose To describe the effect of spaceflight on lower eyelid position.

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, EarlyView.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Astigmatic changes after Descemet membrane endothelial keratoplasty (DMEK) in decompensated penetrating keratoplasty grafts

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the surgery‐induced changes of astigmatism after Descemet membrane endothelial keratoplasty (DMEK) in eyes with failed previous penetrating keratoplasty (PK). Design Retrospective, interventional cohort study based on prospective DMEK database.

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 ...

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.

Variation in measuring and ophthalmic factors correlating with central corneal thickness in the Northern Finland birth cohort eye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess the correlation between optical coherence tomography (OCT) and ultrasound pachymetry (USP) as methods for analysing central corneal thickness (CCT) and to evaluate ophthalmic factors affecting CCT. Methods The eyes of 3070 subjects of the Northern Finland Birth Cohort (NFBC) were examined at the age of 45–49 years.

Femtosecond Laser Created Corneal Allogenic Intrastromal Ring Segments for Keratoconus

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background To evaluate the clinical outcomes of femtosecond laser‐created corneal allogenic intrastromal ring segments (femto‐CAIRS) in keratoconic eyes using a newly described nomogram. Methods This retrospective case series recruited 85 eyes from 75 patients.
