Background: On optical coherence tomography (OCT) scans of the optic nerve head, peripapillary hyperreflective ovoid mass-like structures (PHOMS) are sometimes seen as a sign of axonal distension. The phenomenon has been reported more frequently in myopic subjects. We investigated PHOMS-prevalence in a myopic pediatric cohort, associated risk factors, and PHOMS development over 18 months during low-dose atropine treatment.

Article Synopsis
  • This study examined the effects of low-dose atropine treatment on choroidal thickness changes in Danish children aged 6-12 with myopia over a period of 2 years and a subsequent 1-year wash-out compared to a placebo group.
  • The results showed that children with longer axial lengths had thinner choroidal thickness at baseline, but there were no significant changes in choroidal thickness for the atropine groups compared to placebo after 3 years.
  • Overall, the findings suggested that choroidal thickness remained stable in these children during the follow-up period, with a thinner choroid possibly leading to increased axial elongation in myopia.

We investigated the two-year safety and efficacy of 0.1% loading dose and 0.01% low-dose atropine eye drops in Danish children for reduction in myopia progression in an investigator-initiated, placebo-controlled, double-masked, randomized clinical trial.

The prevalence of myopia is estimated to be 2.6 billion people worldwide and the percentage of individuals with sight-threatening high myopia (≤ -6 diopters) is increasing. Myopia is primarily caused by excessive axial elongation of the eyeball, and treatment modalities attempt to reduce this progression.

Purpose: To investigate the relationship between early post-operative anterior chamber inflammation (aqueous flare) and central corneal thickness (CCT) after cataract surgery and to evaluate the effect of anti-inflammatory prophylaxis on CCT.

Setting: Department of Ophthalmology, Rigshospitalet-Glostrup, University Hospital Copenhagen, Denmark.

Design: Post-hoc analysis of a prospective randomized controlled trial.

Stroke patients admitted for rehabilitation often lack sufficient daytime blue light exposure due to the absence of natural light and are often exposed to light at unnatural time points. We hypothesized that artificial light imitating daylight, termed naturalistic light, would stabilize the circadian rhythm of plasma melatonin and serum cortisol levels among long-term hospitalized stroke patients. A quasi-randomized controlled trial.
