Retinoschisis (OCT Study)
- Peripheral splitting of the retinal nerve fiber layer, most commonly between inner nuclear and outer plexiform layer.
- Symptoms: mostly asymptomatic but may be associated with large peripheral visual field defect in advanced cases.
- 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.
- Observation for asymptomatic cases.
- Treatment is only indicated in symptomatic cases or cases with progressive retinal detachment.
