Multicenter Study
The flipped-classroom approach to teaching horizontal strabismus in ophthalmology residency: a pilot study.
To compare the flipped classroom (home pre-taped lectures followed by in-class group exercise) to the traditional classroom (home reading assignment followed by in-class lecture) for horizontal strabismus didactics in ophthalmology residency. ⋯ The flipped classroom had a favorable effect on test scores for only one of the two strabismus subjects but was preferred over the traditional classroom among PGY3-4 residents.

Multicenter Study Comparative Study
Photographic assessment of retinal hemorrhages in infant head injury: the Childhood Hemorrhagic Retinopathy Study.
Retinal hemorrhages (RH) in babies in the absence of severe trauma or a medical cause have been strongly associated with abusive head trauma (AHT). We examined the pattern of RH in accidental head injury and AHT objectively using widefield retinal imaging. ⋯ Our imaging study confirmed that RH in infants with head injury have a high positive likelihood ratio for AHT. A severe hemorrhagic retinopathy, particularly in association with perimacular folds or macular retinoschisis, has the highest positive predictive value for AHT.

What are the consequences of suddenly legalizing fireworks sales in a largely rural society? Would the spectrum of ocular injuries caused by fireworks differ from those found in the Western world? This is the first study on ocular injuries caused by fireworks conducted in the Republic of South Africa. We analyzed the presenting features and prospectively followed up all patients who presented to the casualties served by our ophthalmic department over the New Year celebrations of 1996-1997. The sale of fireworks to the public had been deregulated the previous year. ⋯ Our findings echo those found in Western countries where fireworks have not been restricted by law. We suggest that young boys, regardless of race, nationality, literacy, or social circumstances, are at risk for ocular injuries caused by fireworks. Countries planning to unban fireworks should aim their education program at this target group.
