It is a
hereditary form of vitreo retinal degeneration characterized by intra retinal
splitting within the macula and in peripheral retina.


Typical (flat) retinoschisis: Adhesion of cystic
lesions as a result of degeneration of neuro retinal and glial supporting
elements within areas of

cystoid degeneration. Deep separation of the retina into an inner and an
outer layer. The inner limiting membrane, retinal vessels, and inner
plexiform layer.


Reticular (bullous) retinoschisis: Thin inner
wall consisting of inner limiting membrane, the nerve fiber layer, attenuated
blood vessels, and complete loss of the supporting radial pillars.



in retinoschisis occurs in the nerve fiber layer. Schisis occurs at the level
of the nerve fiber and ganglion cell layers of the retina due to the
degenerating Muller cells.



Clinical signs and symptoms:

bilateral condition, reduction in visual acuity (peripheral vision loss), scotoma,
retinal tear or hole


Laboratory investigation:

        The full-field electroretinogram (ERG)
b-wave represents the response of Muller cells to bipolar cell activity. The
ERG always shows a lower than normal amplitude ratio of b- over a-waves (b/a
ratio) and a reduced amplitude of oscillatory potentials (OPs). The a-wave
amplitude is normal or near-normal, but the b-wave amplitude will be reduced

      Optical Coherence
Tomography (OCT), which uses light waves to create images of the retina. Visual
Evoked Response (VER) to detect the function of macular portion of the retina
WHICH controls central vision.Ultrasonography or ultrasound may show
abnormalities when a hemorrhage occur in the eye.

Risk factors:

detachment, anchoring of the outer layer of the retina to the eye wall.

(Dry) Age-Related Macular Degeneration (AMD),Retinitis
Pigmentosa,Exudative vitreoretinopathy
