To evaluate the fixation pattern and its relation with preferred retinal locus in eyes with Stargardt disease.


MP-1 microperimetry analysis of fixation patterns in 26 eyes of 13 patients with Stargardt disease was done. Patients visual acuity has changed 1/10 to 2/10. The preferred retinal locus was determined and it's relationship with central scotoma was evaluated.


All eyes had an established preferred retinal locus and all eyes also placed the scotoma above the fixation. Fixation was unstable in 17 eyes (65%) and relative unstable in 9 eyes


Our results showed that microperimetry is an important method for the evaluation of preferential retinal locus and its relationship with fixation in patients with Stargardt disease.
