A 45-year-old male presented to the eye casualty with a history of blurred vision in his right eye. He felt the vision had deteriorated since being struck in the eye with a football 3 days previously.
He had a history of mild amblyopia in the right eye, but otherwise had no previous ocular problems and was emmetropic.
He was fit and well with no medical problems and was taking no medications. He worked as a director of a sales and advertising company. He denied any increase in stress levels in the preceding months and was a nonsmoker with an alcohol intake of less than 30 units a week.
On examination, his visual acuity was 6/36 right and 6/5 left. There were no signs of inflammation in the eye. There was no relative afferent pupillary defect and pupils were equal and briskly reactive to light. The intraocular pressure was 16 mmHg in both eyes. Fundoscopy revealed an area of retinal elevation at the macula measuring two disc diameters. There were no hemorrhages or areas of commotio retinae.
Optical coherence tomography (OCT) performed on the same day showed elevation of the sensory retina at the macula in keeping with CSR [Figure 1]. No treatment was given and the patient was reviewed at 3 months.
At the 3-month review, his vision had returned to 6/9 in the right eye and the macula was flat and dry with no evidence of intra- or subretinal fluid.
