Current research status of optical coherence tomography angiography in hereditary retinochoroidal degeneration / 中华眼底病杂志

ABSTRACT

OCT angiography (OCTA) is a fast,noninvasive and quantifiable new technique,which is especially suitable for long-term follow-up in patients with hereditary retinochoroidal degeneration,such as retinitis pigmentosa,Best vitelliform macular dystrophy,adult onset foveomacular vitelliform dystrophy,doyne honeycomb retinal dystrophy,choroideremia and Stargardt disease.During the follow-up,clinicians can find the subtle signs that explain disease development from the blood flow imaging,quantitatively describe the vascular density,timely detect and treat choroidal neovascularization.It is significant to explore the etiology and monitor the course of these diseases.With the development of more treatments for these diseases,OCTA parameters can also be used as indicators to evaluate and compare different therapeutic effects.In the future,more quantitative indicators of OCTA will be applied to evaluate the course of hereditary retinochoroidal degeneration,and provide valuable basis for early diagnosis and treatment.
