The correlation between choroidal thickness and diabetic retinopathy / 中华眼底病杂志

ABSTRACT

Choroidal thickness and its relevance with retinal disease has been widely studied in recent years,as choroid is an important source of retina blood supply.Diabetic retinopathy (DR) studies have been focused on retinal vascular injury and related circulatory disorders for a long time,however recent studies have found that choroidal blood vessels are also affected by diabetes,including the thickness changes.The choroidal thickness of diabetic patients is thinner than normal.There is no conclusive conclusion about choroidal thickness and the severity of DR lesions,as the choroid thickness results are determined by multiple factors,including diseases,ocular conditions (choroidal vascular status,ocular axial length,refractory errors and other eye parameters),systemic factors (age and sex) and measurement methods.Therefore,it is necessary to calibrate the ocular and extra-ocular factors affecting choroidal thickness when trying to further clarify the relationship between the choroidal thickness and DR.
