Bullous Retinoschisis

Optomap and green separation images (left inferior retina)

Widefield imaging shows an inferior retinoschisis. The lesion has a smooth surface and appears transparent. The blood vessels within the lesion appear darker than those in the surrounding retina.

Spectralis OCT line scan through the retinoschisis

OCT shows splitting of the inner retinal layers. The outer retina remains attached to the underlying RPE.

Optomap and green separation images (left eye)

Widefield imaging shows a round elevated lesion in the inferotemporal periphery (margins identified by the blue arrows). The retinoschisis is translucent in the posterior aspect and retinal vessels appear darker in colour than the surrounding vessels.

Magnified view of the retinoschisis

The retinoschisis is translucent in the posterior aspect and has a smooth surface.
The retinal vessels appear darker in colour than the surrounding retinal vessels. The choroidal detail is slightly obscured within the area of the schisis.

Spectralis OCT line scan through the retinoschisis

OCT shows splitting within the inner retinal layers. There is no underlying retinal detachment.

Optomap and green separation images (right superotemporal retina)

A large retinoschisis can be seen in the superotemporal retina with the posterior border of the schisis best appreciated on the green separation image. There is an associated round outer retinal break that is surrounded by pigmentation indicating chronicity.

The prominent white corrugated anterior border of the retinoschisis was shown by OCT to be rolled outer retina within the retinoschisis. There are also retinal dot/blot haemorrhages at the temporal anterior border.

Spectralis OCT line scans through the hole in the outer retina

Image 1 shows a break in the outer retina. Image 2 shows a localised retinal detachment (centrally in this scan) with an adjacent retinoschisis.

Optomap widefield and green separation image (right inferotemporal retina)

Widefield imaging shows a retinoschisis with adjacent retinal breaks at the anterior aspect. These are most easily appreciated on the green separation image. There is associated pigmentation at the posterior edge of the retinal breaks.

Magnified view of the retinoschisis

The magnified image shows a retinoschisis with adjacent retinal breaks at the anterior aspect. There is associated pigmentation at the posterior edge of the retinal breaks.

Spectralis OCT line scans (vertical and horizontal) through the retinoschisis

Image 1 shows an outer leaf break with fluid underneath the retinal flap (localised retinal detachment). The inner retinal leaf appears intact. Image 2 shows the same detachment using a horizontal line scan. The outer leaf break is apparent in the bottom right corner of the image.
