Choroidal neovascularization silent on optical coherence tomography: report of two cases

Herein, we report two cases of vision loss after successful cataract surgery, associated with drusenoid retinal pigment epithelial detachment without features of choroidal neovascularization on optical coherence tomography along with angiographic examinations suggestive of choroidal neovascularization in which anatomical and functional improvements were achieved with intravitreal injections of anti-vascular endothelial growth factor.

Figure 1
(Case 1): A) Early phase pre-treatment. Left: fluorescein angiography (FA) with discrete foci of parafoveal hypofluorescence as a result of drusen blockage. Right: indocyanine green angiography (ICGA) demonstrates a hyperfluorescent spot in the foveal region (*). B) Late phase pre-treatment. Left: FA shows staining of the drusen. Right: ICGA demonstrates increased hyperfluorescence and better delineation of the foveal lesion (*). C) Pre-treatment optical coherence tomography (OCT) demonstrates an epiretinal membrane and a double-humped PED. D) Early phase post-treatment. Left: FA shows early hyperfluorescence from the drusen. Right: ICGA no longer shows the hyperfluorescent lesion. E) Late phase post-treatment. Left: FA shows staining of the drusen. Right: ICGA demonstrates absence of the hot spot visualized on the pre-treatment ICGA. F) Post-treatment OCT shows that the PED has flattened.

Figure 2
(Case 2): A) Early phase pre-treatment. Left: FA shows a small round hyperfluorescent lesion inferonasal to the fovea. Right: ICGA demonstrates a hypofluorescent foveal dot in the PED. B) Late phase pre-treatment. Left: FA shows an increased area of fluorescein leakage from the lesion. Right: ICGA demonstrates no late changes. C) Pre-treatment multimodal FA/OCT. Of note, the hyperfluorescent dot observed on FA does not correspond to the foveal PED. D) Early phase post-treatment. Left: FA shows absence of the hyperfluorescent dot seen on the pre-treatment FA. Right: ICGA demonstrates transmission hyperfluorescence. E) Late phase post-treatment. Left: No late hyperfluorescent dot is observed on FA. Right: ICGA demonstrates transmission hyperfluorescence. F) Post-treatment FA/OCT demonstrates involution of the PED with atrophy of the outer retina.
