This report is of a 71-year-old woman with unilateral non-traumatic left Purtscher’s retinopathy following shoulder exercises. She developed blurred vision in the left eye a few hours after the exercises. The only clinical findings of note were an ipsilateral tortuous internal carotid artery and multiple cotton wool spots around the left macula region consistent with Purtscher’s retinopathy. To the authors’ knowledge, this is the first report illustrating internal carotid artery tortuosity as an underlying rare cause of Purtscher’s retinopathy.
