FOCAL CHOROID EXCAVATION AND ITS FINDINGS ON ANGIOGRAPHY BY OPTICAL COHERENCE TOMOGRAPHY

Introdução / Purpose

To describe findings and to identify concomitant maculopathy on angiography by optical coherence tomography (OCT - A) in focal choroidal excavation (FCE).

Material e Método / Methods

Report of two cases of FCE submitted to SD / OCT and OCT – A scans by a single examiner.

Resultados / Results

SD / OCT shows area of depression of the external retinal layers, the retinal pigment epithelium (RPE) and the choroid membrane complex in the foveal region in the conforming cases. In non-conforming cases, subretinal space between photoreceptor and RPE layers are observed. In case 1, traction maculopathy is observed in the eye with FCE and choroidal polypoidal vasculopathy in the fellow eye. OCT - A images presents a hyperreflectivity in the choriocapilaris layers that could correspond to increased vascular flow and consequent choroidal neovascularization (CNV) in right eye in case 1 and left eye in case 2.

Discussão e Conclusões / Conclusion

FCE may be associated with maculopathy. SD / OCT and OCT - A shows tractional maculopathy in one eye and CNV in both eyes of patients with FCE. Choroidal polypoidal vasculopathy was found in the fellow eye in one of the patients. A few is known about this disease spectrum. In this present study we can observe, as previously described, that there may be maculopathy associated in both affected eyes with FCE and also in the fellow eye. However, our study differs from the speculation previously described regarding the involvement of tractional maculopathy and focal choroidal excavation morphology. In addition, we added findings with the presence of both morphologies types in the same eye.
