Examination revealed a localised area of conjunctival congestion and sloughing, inferonasal to limbus indicating the site of the sting injury (Figure 1 (Fig. 1)).
Color fundus photograph of the eye at presentation. Internal limiting membrane (ILM) folds over the macula and mild disc hyperemia are noteworthy.

Fundus examination revealed mild vitreous haze, mild disc hyperemia, and retinal striae at the macula (Figure 2 (Fig. 2)).
Three weeks after presentation. Color fundus montage of the right eye reveals minimal media haze overlying the affected quadrant with an area of chorioretinal pigmentation.

Fundus examination revealed minimal vitritis overlying the affected quadrant with an underlying area of chorioretinal pigmentation (Figure 3 (Fig. 3)).
Global ERG reveals reduced scotopic responses and depressed oscillatory potential in the right eye. Photopic response was normal.

Global electroretinogram (ERG) revealed reduced scotopic response and depressed oscillatory potentials in the right eye (Figure 4 (Fig. 4)), even though the photopic response amplitude was normal.
Multifocal ERG (trace array) reveals preserved macular function in the right eye.
