Figure 1
Case I. Fundoscopy, at presentation, on one-week and five-week follow-up. Follow-up images show diminishment of vitreous haze and regression of optic disc swelling.
OD(R) = oculus dexter (right); OS(L) = oculus sinister (left)

Figure 2
Case I. Optical coherence tomography (OCT) of optic discs. Optic disc drusen at presentation and on a five-week follow-up. No alteration in optic disc drusen size is visible. Up images show diminishment of vitreous haze and regression of optic disc swelling.

Figure 3
Case I. Fluorescein angiography at presentation. Early and late frames. Contrast blockage in the upper temporal part of the right optic disc (white arrow), corresponding to a peripapillary haemorrhage. Hypofluorescent dots (black arrow) corresponded to hyperreflective spots on optical coherence tomography (OCT). Fluorescein angiography five weeks on methylprednisolone treatment. Early and late frames. Diminishment of the contrast blockage in the upper temporal part of the right optic disc (white arrow) corresponding to a peripapillary haemorrhage. Hypofluorescent dots (black arrow) are less prominent.
OD(R) = oculus dexter (right); OS(L) = oculus sinister (left)

Figure 4
Case I. Optical coherence tomography (OCT) of optic discs, at presentation, one week on methylprednisolone treatment, five weeks on methylprednisolone treatment. Follow-up shows regression of optic disc swelling.
OD(R) = oculus dexter (right); OS(L) = oculus sinister (left)

Figure 5
Case II. (A) Fundoscopy, prior to non-small cell lung cancer diagnosis in 2013: posterior pole and peripheral retinal changes. (B) Colour fundus photography at presentation in March 2021: multiple flat, grey-white lesions (black arrows) are visible at presentation. (C) Three weeks on methylprednisolone treatment in April 2021: a diminishment of lesions (white arrows) is observed.
OD = oculus dexter; OS(L) = oculus sinister

Figure 6
Case II. (A) Macular optical coherence tomography (OCT) presentation and (B) two weeks on methylprednisolone treatment. Loss of ellipsoid zone and hyperreflective haze in outer plexiform and outer nuclear layers is evident at presentation. Indocyanine angiography at presentation shows hypofluorescent lesions corresponding to ellipsoid zone disruptions (white arrows). Two weeks on methylprednisolone treatment ellipsoid zone appears granular.
OD = oculus dexter; OS(L) = oculus sinister

Figure 7
Case II. Fluorescein angiography at presentation, early and late frames. Note surface capillary net dilatation and late staining of the papilla and hypofluorescent areas on the posterior pole and periphery. Indocyanine angiography at presentation showing hypofluorescent lesions.
OD = oculus dexter; OS(L) = oculus sinister
