Olfactory Function Assessment of Blind Subjects Using the Sniffin' Sticks Test.

Abstract

Objective In recent years, a growing number of studies have focused on the olfactory abilities of blind individuals as well as their tactile and auditory senses. In this study, we aimed to investigate possible alterations in the sense of smell in early- and late-blind subjects as compared with sighted controls, using a Sniffin' Sticks test battery.
