Overview
X-linked retinoschisis is an X-linked recessive retinal dystrophy and the most common juvenile-onset retinal degeneration in males, with onset in the first or second decade. The macula shows fine radiating spoke-wheel folds from splitting of the retinal layers, and about half of patients also have peripheral retinal changes. Vision can stay fairly good in childhood unless retinal detachment or vitreous haemorrhage occurs. The optometry role is to recognise it with OCT, refer to establish the diagnosis, and act quickly on detachment or haemorrhage symptoms.
Recognition
Symptoms: what patients report
- A boy with mildly reduced acuity in both eyes, often picked up at school screening.
- Reading difficulty that spectacles do not fully correct.
- Sudden loss of vision, floaters or a shadow raises concern for vitreous haemorrhage or retinal detachment.
Signs: what the examination shows
- Fine radiating folds at the fovea in a spoke-wheel pattern, in both eyes.
- Peripheral retinal degenerative change in about half of patients.
- OCT: splitting between the inner and outer retinal layers with cyst-like spaces at the macula.
- Fundus autofluorescence: reduced central signal with a brighter rim; the spoke-wheel pattern may show as absent signal at the fovea.
- Older adults: macular atrophy may replace the schisis.
