Do Patients With Candidemia Need an Ophthalmologic Examination?

Background: The Infectious Diseases Society of America recommends a screening dilated retinal examination by an ophthalmologist for all patients with candidemia. Conversely, the American Academy of Ophthalmology recommends against routine screening in patients with candidemia without symptoms.

Methods: In a collaborative effort between infectious diseases and ophthalmology, we examined the incidence of ocular complications in 308 patients with candidemia and subsequently measured the rate of fundoscopic examinations, risk factors for ocular complications, management changes, and outcomes.

Factors affecting two-point discrimination in Argus II patients.

Two of the main obstacles to the development of epiretinal prosthesis technology are electrodes that require current amplitudes above safety limits to reliably elicit percepts, and a failure to consistently elicit pattern vision. Here, we explored the causes of high current amplitude thresholds and poor spatial resolution within the Argus II epiretinal implant. We measured current amplitude thresholds and two-point discrimination (the ability to determine whether one or two electrodes had been stimulated) in 3 blind participants implanted with Argus II devices.
