|History: This 58 year-old woman was referred
to the eye casualty by her optician with a diagnosis of a right superior
retinal detachment. The patient was asymptomatic and the vision was 6/6
in both eyes. Fundoscopy revealed a raised dome shaped lesion in the right
superotemporal peripheral retina consistent with retinoschisis. Retinoschisis
is caused by splitting of the retina usually in the outer plexiform layer.
Retinal detachment is an uncommon complication. The majority of cases are
asymptomatic and progression to involve the macula is rare. No further
appointment was made for this patient but she was advised to contact the
casualty if there was any visual changes.
