Purpose:
This study presents a series of 10 patients who posed a diagnostic challenge regarding the diagnosis of acquired retinoschisis (RS) or retinal detachment (RD), where spectral-domain optical coherence tomography (OCT) with the Spectralis HRA and OCT device (Heidelberg Engineering, Heidelberg, Germany) was able to help make a correct diagnosis.
Methods:
Ten patients (five with acquired RS and five with RD) were referred to a vitreoretinal clinic at Moorfields Eye Hospital for definitive diagnosis and further management. All patients underwent scans with the Spectralis HRA and OCT device.
Results:
The Spectralis HRA and OCT was able to make a clear diagnosis of RS or RD in all patients. Of the five patients with RS confirmed on OCT, two were referred with RD, and of the five patients with RD, four were referred with RS. New OCT features of RS include the double schisis cavity phenomenon, intraretinal pillars through the schisis cavity, and irregularity of the inner surface of the attached outer leaf.
Conclusion:
Spectral-domain OCT is a useful tool in distinguishing RS from RD, eliminating previous diagnostic uncertainty. The Spectralis HRA and OCT device has the added advantages of being able to reliably image anterior retinal pathology and produce high-definition images.
