1 ‘Poppers’ retinopathy.
‘Poppers’ retinopathy. The cross-sectional OCT, centred on the macula, demonstrates clear disruption of the inner/outer retinal segment. The patient presented with sudden bilateral visual loss after inhalation of ‘poppers’, likely isopropyl nitrite, which is toxic to central photoreceptors and was referred to neurology from an eye casualty as bilateral optic neuritis. OCT, optical coherence tomography.
