A Rare Case of Foveal Hypoplasia With Dyschromatosis Universalis.

Foveal hypopalsia (FH) is typically seen in association with diseases like albinism and aniridia, and familial FH (FFH) is very rare. The authors present a case of unique association of FH with dyschromatosis universalis hereditaria (DUH). Family members of this patient had history of nystagmus and dermal pigmentary anomalies, suggesting that this may represent FFH with DUH in X-linked pattern. The authors also discuss the role of pigment anomalies in manifesting as this combination. [Ophthalmic Surg Lasers...

Analytical strategy for assessment of usability of medical devices from the user's perspective: a study of hemodialysis patients.

Studies have shown the importance of including the user's experience in measuring the usability of medical devices. Still, the user's assessment depends on the context of use for the treatment received. To measure the usability in such a way as to separate these effects and understand the sources affecting users' perceptions, the article proposes an analytical strategy that assesses the effect of the context of use on measuring the device's usability. Next, we create indicators that are free of these effect...
