- Peripheral splitting of the retinal nerve fiber
layer, most commonly between inner nuclear and outer plexiform layer.
- Clinical features:
- Symptoms: mostly asymptomatic but may be
associated with large peripheral visual field defect in advanced
cases.
- Signs:
- Usually bilateral, located inferotemporally
and very-slowly progressive.
- Well-circumscribed, dome-shaped elevation
of the inner retina which extends anteriorly towards the ora
serrata.
- The retinal surface usually appears
normal but may frequently have sheathed vessels and whitish
snowflake opacities.
- May be complicated by retinal breaks,
hole formation on either the inner or outer retinal layer,
retinal detachment or macular compromise if the schisis advances
posteriorly.
- Management:
- Observation for asymptomatic cases.
- Treatment is only indicated in symptomatic
cases or cases with progressive retinal detachment.
