SD OCT shows retinoschisis to be more common, diverse than previously thought

CHICAGO – Results from a retrospective analysis showed that imaging with spectral domain ocular coherence tomography can provide more information on the pathophysiology of retinoschisis, as reported in a poster here at Optometry’s Meeting.
Richard J. Madonna, OD, and colleagues conducted a retrospective analysis of 24 patients with X-linked or acquired retinoschisis, as well as those with associated congenital anomalies. Images of the optic nerve, macula and retinal periphery were taken with one of four commercially available SD OCT systems.
The researchers imaged a wide variety of findings that ranged from “those visible to ophthalmoscopy to those clearly visible to fundus examination and affecting large areas of the retina,” according to the poster.
Half of the patients had myopia greater than 6 D, and these patients “presented with the most unexpected findings and often presented with schisis invisible to ophthalmoscopy,” the poster stated.
The imaging in various patients showed 360-degree peripapillary schisis, schisis associated with retinal detachment and foveal schisis, “all invisible to ophthalmoscopy,” the researchers said.
“Imaging findings have provided keys to understanding the pathophysiology of the condition and insight into more effective treatments for those requiring it,” they concluded.
