Autofluorescence of Choroidal Hemangioma in 34 Consecutive Eyes

Abstract

Choroidal hemangioma shows little intrinsic AF. Overlying orange pigment and fresh subretinal fluid show hyper-AF and retinal pigment epithelium hyperplasia and atrophy show hypo-AF.

Imaging of retinal and choroidal vascular tumours

“…By contrast, chronic subretinal fluid is hypofluorescent relative to the surrounding tissue. 27 Following treatment, the relative hypofluorescence of the haemangiomas is more pronounced. 27 Diffuse choroidal haemangiomas are usually associated with Sturge-Weber syndrome.…”

“…27 Following treatment, the relative hypofluorescence of the haemangiomas is more pronounced. 27 Diffuse choroidal haemangiomas are usually associated with Sturge-Weber syndrome. They more closely resemble a diffuse choroidal angiomatosis than a localized vascular tumour.…”

“…These include suband intraretinal fluid, retinal schisis, photoreceptor loss, and retinal atrophy. 17,20,27,28 However, the retina overlying the haemangioma may be normal. 20 The RPE layer usually shows a dome-shaped uninterrupted elevation over the haemangioma.…”

“…31 Similarly, the autofluoresence pattern of diffuse choroidal haemangioma is similar to that of circumscribed lesions. 27 …”

“…19 Autofluoresence imaging shows choroidal haemangioma to be hypo-or isofluorescent relative to the surrounding tissue. 27 The autofluorescence shows mainly a granular pattern. Orange pigment overlying the haemangioma is strongly hyperfluorecent, whereas localized fibrosis and RPE atrophy are hypofluorescent (Figure 2).…”
