Lead in statement: The following patients all have retinal degenerations. Please choose the most appropriate diagnosis from the list above.
Stems:
1. A 43-year-old hypermetrope was referred by optician for abnormal superior field defects.
2. A 35-year-old lady presented to eye casualty complaining of sudden onset flashes in her right-eye. Peripheral fundus examination showed multiple circumferentially oriented bands of retinal atrophy. She had retinal detachment repair 2 years ago in her left-eye.
3. A 60-year-old asymptomatic man was seen in the eye clinic. Peripheral fundus examination showed circumferentially oriented bands of whitish frost-like islands. There was no associated retinal break.
4. A 40-year-old myope presents with bilateral presenile cataracts. Fundus examination reveals bilateral rhegmatogenous retinal detachment. He has an abnormality on chromosome 2q36.
