Outcome Measures

Primary Outcomes (1)

  • Quantitative changes of parafoveal microvasculature in eyes with exudative circumscribed choroidal haemangioma

    Quantitative changes of parafoveal microvasculature in eyes with exudative circumscribed choroidal haemangioma compared wiyh healthy eyes.

    3 years

Study Arms (2)

The exudative CCH group

Treatment naïve patients with exudative CCH which caused subfoveal retinal detachment and/or intraretinal fluid

Other: This is observational study with the examination of OCTA

The healthy eye control group

In the healthy eye control group, all eyes should have no ocular diseases and the best-corrected visual acuity (BCVA) should be 20/20 or better.

Other: This is observational study with the examination of OCTA

Study Population

There are two groups in this study: one is the exudative CCH group,and the other is the healthy eye control group. They performed OCTA at baseline.

You may not qualify if:

  • without any other ocular diseases or any severe uncontrolled systemic diseases, including uncontrolled hypertension, coronary heart disease, liver failure, and kidney failure. all the subjects with high diopter \> -6D, long eye axis \> 26.0 mm, or the quality of the acquired OCTA images below 7/10 should be excluded from this study.
