Fixation features of foveoschisis in pathological myopia / 中华眼底病杂志

ABSTRACT

Objective To observe the fixation features of foveoschisis in pathological myopia patients.Methods 36 patients(42 eyes)with>-6.00D myopic degree and foveoschisis who diagnosed by optical coherence tomography were included.The patients were divided into foveoschisis with retinal detachment group(11 eyes),foveoschisis with macular hole group(12 eyes)and only foveoschisis group(19 eyes).Micro-perimeter MP-1 was used to identify the fixation location and fixation stability.Results The eccentric fixation were formed above the foyea in the foveoschisis with retinal detachment and foveoschisis with macular hole group,the fixation location was formed on fovea in the only foveoschisis group.The fixation stability of the foveoschisis with retinal detachment,foveoschisis with macular hole and only foveoschisis group were(23±4)0A,(59±6)% ,(91±11)% respectively,the difference was statistically significant(F=243.47,P＜0.01).Conclusions The fixation location is formed on foyea in the patients with foveoschisis in pathological myopia.The eccentric fixation is formed above the fovea in the patients who has foveoschisis with retinal detachment and macular hole in pathological myopia.
