Morning glory syndrome with contractile peripapillary staphyloma.

We report a case of morning glory syndrome and discuss the clinical symptoms and echographic patterns.This malformation is attributed to the presence of an autonomous cholinergic mechanism situated at the posterior pole of the eye.Morning glory syndrome is a congenital anomaly of the posterior pole which is characterised by an ectasia of the posterior pole of the fundus involving the optic disc.In addition there is a slightly protruding pigment ring in the peripapillary area, and nonbranching veins protrude in radial formation from the ectasia.Recognition of veins and arteries is always difficult.The peripheral retina appears normal.This unilateral malformation is often associated with myopic astigmatism and consequent diminution of vision.
