Abstract
 
Purpose
 

Using conventional B-scan, it may not be possible to differentiate individual retinal layers to distinguish retinoschisis (RS) from retinal detachment (RD). We performed a retrospective study to report the ability of high-resolution ultrasonography (USG) B-Scan in differentiating between acquired RS and RD, and compared the findings with spectral-domain optical coherence tomography (SD-OCT).

 
Methods
 

Patients with acquired peripheral RS and RD undergoing imaging with high resolution B-scan USG and SD-OCT were included in the study. RS was considered in the presence of an immobile, dome-shaped visible elevation of the peripheral retina. SD-OCT images were obtained with the Spectralis OCT. A 20°×15° horizontal raster-line scan, encompassing the attached and detached retina was obtained for each patient. B-scan USG was performed using Ellex Eye Cubed ®. Descriptive analysis was performed on the images obtained by high-resolution B-scan USG and SD-OCT to identify various retinal layers.

 
Results
 

Six eyes of 5 patients (2 males) with RS, 7 eyes of 4 patients (3 males) with RD and 1 eye of a patient with schisis-detachment were included in the study. In all eyes of patients with RS, the attached outer retina demonstrated the presence of two hyper-reflective layers corresponding to the outer plexiform layer (OPL) and retinal pigment epithelium (RPE). Eyes with RD demonstrated two hyper-reflective layers in the detached portion, corresponding to the nerve fiber layer and OPL, whereas the attached portion demonstrated the presence of the third hyper-reflective layer, i.e. RPE (figure). These findings correlated well with SD-OCT.

 
Conclusions
 

Analysis of retinal layers on high-resolution USG B-scan may allow precise differentiation of acquired RS from RD by identification of various retinal layers. These findings correlate well with SD-OCT.  

 
High-resolution ultrasound (USG) B-scan of eyes with (A) RS and (B) RD. (A) shows that eyes with RS demonstrate a thin single hyper-reflective line representing RNFL (blue arrowhead). Schisis cavity is marked by a blue asterisk. The attached OPL and RPE layers are shown with a white and yellow arrowhead. (B) shows that eyes with RD demonstrate the presence of two hyper-reflective lines representing RNFL and OPL (blue and white arrowheads). The red asterisk marks subretinal space overlying RPE layer, which is attached (yellow arrowhead)
