Ein ungewöhnlicher Fall eines vertikalen Pseudostrabismus

Purpose: This case report describes a rare case of vertical pseudostrabismus. Material and Methods: A case of a four-year-old female patient is presented to evaluate the necessity of occlusion therapy. The treatment options are based on orthoptic and ophthalmological examination, as well as a review of the literature. Results: The fully corrected visual acuity was 20/80 (logMAR 0.6) in the right eye and 20/200 (logMAR 1.0) in the left eye. Corneal reflex examination revealed a slight esotropia and a pronounced vertical deviation of the right eye (right over left). However, the cover test did not detect a misalignment. Fundus examination revealed retinopathy of prematurity with macular ectopia. Conclusion: Vertical eccentric fixation is a rare condition. Therefore, treatment should be tailored to the patients’ needs.
