Long-term outcomes of recess / resect for sensory XT

The purpose of this study was to evaluate relationships between initial and long-term outcome of unilateral recess / resect surgery in adult sensory exotropia, factors associated with long-term outcome, exotropia drift and time to failure follow-up surgery. This was a...

Infantile exotropia surgical outcomes

This study investigates the success rate and dose response of bilateral lateral rectus muscle recessions (BLL) and bilateral lateral rectus muscle recessions plus unilateral medial rectus resection (LMR) on basic type infantile exotropia of 20–45PD. This was a retrospective review...

Management of squint with near-distance angle disparity

These are a group of strabismus disorders where the angle of misalignment is different between near and distance. The focus of this article will be on the patients where the angle for near exceeds the distance angle by more than...

The blue-light hazard – is it true?

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: The blue-light hazard – is it true? Blue light is part of the visible optical spectrum...

Prism fusional vergence measures for Risley vs prism bar measurements

This study sought to investigate the agreement between the phoropter Risley and the prism bar prism fusional vergence amplitudes among a normal sample of Ghanaian children aged 8–17 years. This was a school-based study of 2300 children. Of 2300, 116...

Three muscle surgery results for ET

There is limited information in the literature on the outcomes of three muscle surgery. The authors aimed to evaluate the medium term motor outcomes of three horizontal muscle surgery in 18 patients with large angle infantile esotropia of at least...

Recurrent corneal erosions secondary to isotretinoin use

Isotretinoin (13–cis-retinoic acid) is the first line treatment for moderate to severe nodulocystic or papulopustular acne [1,2]. Although it is a safe medication, it has several adverse side-effects, including ophthalmic manifestations, as shown in Table 1 [3]. These side-effects need...

Decisions on correction of low, moderate and high hypermetropic in exotropia

The purpose of this systematic review was to evaluate the management strategies and outcomes for hypermetropic patients with exotropia, and to determine implications of refractive correction decisions in optimising clinical outcomes. 10 studies met the inclusion criteria from 6 countries...

Immediate postop alignment differences between adult and childhood ET

The purpose of this study was to investigate the immediate postoperative alignment among patients undergoing successful surgery for esotropia and to determine whether there are any differences between children and adults. This was a retrospective case review of 544 cases;...

BT as an effective alternative treatment for small angle consecutive exotropia

In this study, the authors evaluate the efficacy of botulinum toxin A (BTA) as a treatment option for consecutive exotropia. This was a retrospective review of 34 patients; 23 female and 11 male. Age at BTA was a mean of...

Iranian prevalence of strabismus and heterophoria

Previous studies in parts of Iran report a childhood prevalence of strabismus of 1.2 to 2.3%. The authors aimed to evaluate the prevalence of strabismus in underserved rural areas of Iran in all age groups. In 2015 they conducted a...

Strabismus and binocular summation

The authors conducted a pilot study to investigate the effect of visual noise or background complexity on binocular summation in patients with strabismus. A target embedded in pixel noise was used. The study involved performance of a task detecting a...
