OCT angiography metrics in children

This prospective study aimed to quantify the vessel density of both the macular and optic nerve and foveal avascular zone (FAZ) values in 92 normal eyes of 92 children (42 boys, 50 girls) aged 13.4 ±2.65 years (seven to 18)....

Would automated pupillometry be a useful addition when assessing acute vision loss?

The authors present a two-part study, the first part being an electronic survey of ophthalmologists and optometrists to identify barriers to the routine clinical use of automated pupillometry and the second, a clinical study comparing the swinging light tests and...

Prisms to treat AACE

Of 128 patients reviewed with binocular dysfunction, 30 (23.4%) had acute acquired concomitant esotropia (AACE). These patients complained of sudden onset diplopia at distance with no or moderate problems at near. There was no previous history of strabismus. Mean age...

Outcomes for IRS implantation for keratoconus

The authors report visual and topographic outcomes of intracorneal ring segment (ICRS) implantation alone or in combination with corneal cross linking (CXL) and long-term results in halting keratoconus in paediatric patients. This study was a retrospective design including 19 patients...

Medium-term outcomes following photo screening

A photo-screening project of preverbal children was conducted in 2016 in Portugal consisting of enrolment of two-year-old children and referral of these if having a positive screen to paediatric ophthalmology plus a screen of four-year-old children who missed or had...

Outcomes for acute acquired non-accommodative comitant esotropia

Outcomes are reported in a retrospective review of 338 patients with acute acquired non-accommodative comitant esotropia (AACE). Mean age at presentation was 12.60 ±9.37 years and 220 were male, 118 female. Best corrected visual acuity was 0.2 ±0.29 logMAR overall;...

Paediatric ophthalmology five-year results of atropine 0.01% efficacy in the myopia control in a European population

This a prospective, randomised and longitudinal study from Madrid, Spain in 361 eyes from 361 children randomised into the control group (177 eyes with no treatment) and the treatment group (184 eyes with 0.01% atropine drops once daily). Complete eye...

Three-year results of 0.01% and 0.1% loading dose atropine treatment including washout in Danish children with myopia: a placebo-controlled, randomised clinical trial

This was a placebo-controlled, double-blind, randomised clinical trial of 97 children to examine the safety and efficacy of low-dose atropine (0.1% and 0.01% loading dose) after 2-year treatment and 1-year washout in 6–12-year-old Danish children with myopia. Ninety-one children were...

Keratoconus prevalence in astigmatic adolescents

The authors from Israel performed a cross-sectional study of 896,377 adolescents aged 16–20 years who underwent refraction and topography/tomography between 2011 and 2022. A total of 1886 (0.21%) were diagnosed with keratoconus with increasing astigmatism level being strongly associated with...

Orthokeratology lens treatment for exophoria of convergence insufficiency type

The purpose of this study was to evaluate the effectiveness of orthokeratology (OK) lenses with an increased comparison factor (ICF) of 1.75D in the treatment convergence insufficiency (CI) exophoria (EP). This was a prospective, self-controlled study of 60 eyes (30...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...
