Choroidal excavation is a recently described entity.[1] Focal choroidal excavation (FCE) with PCV has been reported before.[2] Optical coherence tomography angiography (OCT-A) features of PCV have also been described.[3] Hereby, we describe clinical and imaging features of juxtapapillary choroidal excavation (JCE) with PCV. To the best of our knowledge, JCE and PCV have not been reported together before.


  Case Report Top


A 27-year-old-lady presented with decreased vision in right eye, of 3-year duration. Best corrected visual acuity was 20/60. Left eye was normal. Fundus examination revealed juxtapapillary retinal pigment epithelium-choroidal atrophy [Figure 1] with overlying subretinal fluid [Figure 1], and cystoid macular edema. Clinical findings were confirmed with swept-source OCT [Figure 2]. A hyperreflective polypoidal lesion was seen within area of choroidal excavation [Figure 2]. Fundus fluorescein angiography showed diffuse hyperfluorescence corresponding to choroidal excavation [Figure 3] and progressive focal hyperfluorescence corresponding to polypoidal lesion [Figure 3]. OCT-A showed lack of choriocapillaris within the area of choroidal excavation [Figure 4]. A hypoflow structure surrounded by a hyperflow area was also seen in the choriocapillaris at the same level [Figure 4]. Although indocyanine green angiography is investigation of choice for PCV, requisite information could be gathered from OCT-A in our case.

A hyperflow network is seen in OCT-A at the level of the polypoidal lesion in swept-source optical coherence tomography (broad arrow). A hypoflow structure surrounded by a hyperflow area is also seen in the choriocapillaris at the same level (white arrowhead)

  Discussion Top


FCE has an association with PCV.[2] Individually, OCT features of FCE and PCV have been well documented.[4] OCT-A features of PCV have been described.[5] In our case, JCE appears as a hypoflow area. This can be attributed to choriocapillaris attenuation in this region. It is possible that a prior episode of subretinal bleeding from polypoidal lesion is responsible for choroidal atrophic changes, but a cause–effect relationship is hard to establish in the absence of a longitudinal study. Larger studies with longer follow-up are required to understand the two entities better.
