Refraction results in ROP with and without IVB

The authors aimed to compare refractive results of intravitreal bevacizumab (IVB) injection in premature neonates with retinopathy of prematurity (ROP) versus infants with spontaneous regression of ROP. The study included 87 infants (174 eyes). Group 1 included 38 infants (76...

Objective vs. subjective torsion measures

This study aimed to explore the relationship between subjective and objective torsion in normal individuals with no manifest strabismus. The study included 118 eyes of 59 normal people aged >15 years using Heidelberg OCT and the Torsionometer. There were 27...

VA and stereo changes with increasing Bangerter filters

This study investigated the effect of monocular blur induced by Bangerter filters (BF) on both monocular and binocular visual acuity (VA) and stereoacuity in normal visual systems. Subjects included 24 healthy student volunteers aged 20.33 ±1.79 years; 22 female. One...

Optic canal measurements in children

The authors aimed to determine the normal range of optic canal diameters in a Turkish pediatric population. They evaluated 200 CT examinations: 102 females, 98 males with mean age of 86.42 ±65.39 months (range 1-211). There was no significant difference...

Mapping areas to target location of vision screening services

In this study, the authors analysed data from a community vision screening program to determine the efficiency of vision screening in reaching lower income populations. The study used ArcGIS (Esri) mapping software to develop a visual representation of areas needing...

Patients prefer vision from lasik than from smile in a contralateral-eye trial

This prospective, randomised, single surgeon, contralateral-eye clinical trial compared the results in myopic patients undergoing wavefront-guided femtosecond laser in situ keratomileusis (LASIK) in one eye and small-incision lenticule extraction (SMILE) in the fellow eye. The patient-reported outcomes with laser in...

Effective contrast ratio as a measure of binocular visual perception

The authors used a binocular phase combination paradigm to quantitatively evaluate and compare the binocular visual perception of normal individuals and patients with different types of strabismus to understand the binocular visual perception of patients with strabismus and evaluate whether...

Changes in C:D ratio of premature infants with enlarged C:D ratios

This retrospective observational study examined the longitudinal alterations in cup to disc ratio (CDR) among premature infants exhibiting enlarged CDR and normal intraocular pressure (IOP) up to two years. Among the 283 infants, 13.4% manifested an enlarged CDR. In this...

Comparison between findings in ‘active’ or ‘healed’ giant cell arteritis

Giant cell arteritis (GCA) is the most common systemic vasculitis in older people and can cause devastating sight loss if untreated. Temporal artery biopsy is often relied upon for diagnosis by ophthalmologists, with a positive biopsy result indicating whether the...

Contrast sensitivity comparisons for Pelli Robson, Hiding Heidi and Double Happy tests

The authors aimed to compare contrast thresholds and measure agreement across current paediatric assessment of contrast sensitivity with Hiding Heidi and Double Happy contrast sensitivity tests vs. the gold-standard Pelli Robson chart. Reduced contrast levels were similar under different light...

MPH treatment effect in ADHD on choroidal vascular index

In this study the authors aimed to investigate the choroidal vascular index (CVI) in treatment-free children with ADHD, children regularly taking methylphenidate (MPH) and healthy controls. This was a prospective cross-sectional study of 52 patients with newly diagnosed ADHD, 46...

Normative reference values for optic nerve sheath diameter in children

The purpose of this study was to measure optic nerve sheath diameter (ONSD) in paediatric patients without pathology using brain CT performed for various reasons and to provide normal tomographic reference values. This was a retrospective study of CT scans...
