Su Ann Tay, Sonal Farzavandi, Donald Tan
Efforts to reduce the progression of myopia in childhood are on the rise, due to an increasing incidence of myopia worldwide and its associated sight-threatening complications. Interventions are aimed at reducing myopia in childhood and include environmental considerations, spectacles, contact lenses, and pharmacological agents. We reviewed recent literature with interventions aimed at reducing myopia progression in children and found that a number of interventions were significant in reducing the progression of myopia...

BACKGROUND: A rating scale is a critical component of patient-reported outcome instrument design, but the optimal rating scale format for pediatric use has not been investigated. We compared rating scale performance when administering potential questionnaire items to children with eye disorders and their parents. METHODS: Three commonly used rating scales were evaluated: frequency (never, sometimes, often, always), severity (not at all, a little, some, a lot), and difficulty (not difficult, a little difficult, difficult, very difficult)...

PURPOSE: To generate a statistical model for personalizing a patient's occlusion therapy regimen. METHODS: Statistical modelling was undertaken on a combined data set of the Monitored Occlusion Treatment of Amblyopia Study (MOTAS) and the Randomized Occlusion Treatment of Amblyopia Study (ROTAS). This exercise permits the calculation of future patients' total effective dose (TED)-that predicted to achieve their best attainable visual acuity. Daily patching regimens (hours/day) can be calculated from the TED...

PURPOSE: Extensive literature exists on normative stereoacuity values for younger children, but there is less information about normative stereoacuity in older children/adults. Individual stereotests cannot be used interchangeably-knowing the upper limit of normality for each test is important. This report details normative stereoacuity values for 5 near/distance stereotests drawn from a large sample of participants aged 16-40 years, across 3 studies. METHODS: Participants (n=206, mean age 22...

Restrictive strabismus resulting from the presence of an accessory extraocular muscle has rarely been reported in the literature. Most articles written on this topic are isolated case reports. The purpose of this paper is to describe a series of 7 similar patients presenting with atypical restrictive strabismus associated with enophthalmos in the affected eye, which was found to be caused by an accessory extraocular muscle attached to the posterior globe near the optic nerve. The medical records of 7 patients who shared these clinical characteristics were retrospectively analyzed...

Gregory Tsoucalas, Markos Sgantzos
The eminent Greek physician Paul of Aegina, native of the Saronic island Aegina and pupil of the Alexandrian School, understood both exotropia and endotropia, his designation for esotropia and proposed therapeutic measures for their treatment during baby or toddler age. He had introduced an innovative method for the newborns to have a straight vision, "the congenital strabismus of the newborns must be treated with the placement of a facial mask (with 2 open holes in the middle axes of the eyes), so that the babies could only see in a straight line", combined with a small oil lamp to assure a direct eye alignment...
