The Preferred Retinal Locus for Reading in Central Vision Loss.

ABSTRACT:

Purpose

People with central vision loss (CVL) often adopt a preferred retinal locus (PRL) for fixation outside the region of central loss. However, it is unknown how often the fixational PRL (fPRL) is used in reading. Here, we assessed if the reading PRL is in the same location as the fPRL.

Methods

Participants read text on a computer screen. Reading was randomly interrupted by blanking the screen, and participants reported the word being read when the blanking occurred. The location of this word was compared to the fPRL location, measured with an eye tracker. If reading uses the fPRL, the two locations should overlap. We validated our method with 10 normally sighted controls for whom the fPRL and reading PRL should coincide at the fovea. We then tested 20 participants with
