Fundus autofluorescence in chronic essential hypertension.

Purpose: To evaluate fundus autofluorescence (FAF) changes in patients with chronic essential hypertension (HTN).

Methods: In this case-control study, 35 eyes of 35 patients with chronic essential HTN (lasting >5 years) and 31 eyes of 31 volunteers without history of HTN were included. FAF pictures were taken from right eyes of all cases with the Heidelberg retina angiography and then were assessed by two masked retinal specialists.

Prevalence of pulmonary hypertension in patients undergoing hemodialysis.

The prevalence of hemodialysis-induced PH is still a subject of debate. The goal of the present work was to determine the prevalence of PH in patients undergoing hemodialysis.
