Occurrence of circumscribed choroidal hemangioma accompanied by polypoidal choroidal vasculopathy and branch retinal vein occlusion: a case report

BACKGROUND: Circumscribed Choroidal hemangioma (CCH) is a kind of hamartoma that is caused by congenital vascular malformation. And, polypoidal choroidal vasculopathy (PCV) is an exudative maculopathy. There is no literature indicating that there is a correlation between the occurrences of CCH and PCV. CASE PRESENTATION: A 66-year-old male presented with decreased vision of his left eye for 4 years. Fundus photograph showed that the branches of blood vessels at the supratemporal retina were occluded in white lines, an orange lesion could be seen in the subnasal retina and mottled, yellowish white lesions were accompanied by punctate hard exudation in the macular in the left eye. The Fundus autofluorescence (FAF), fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and Spectral domain optical coherence tomography (OCT) were done. There was a diagnosis of CCH, PCV and branch retinal vein occlusion accompanied with retinoschisis of the left eye. CONCLUSION: This article reports on a case of an elderly male Chinese patient with CCH and PCV accompanied by branch retinal vein occlusion with retinoschisis in the left eye. The common lesions are choroidal vascular abnormalities. Whether hypertension is related to CCH, PCV and branch retinal vein occlusion remains to be further studied.
