Morning glory syndrome.

Morning glory syndrome is a congenital optic disc anomaly in which much of the excavated colobomatous optic disc is filled with glial tissue. Ocular complications may include strabismus, reduced visual acuity and retinal detachment and it may have systemic associations as in Aicardi's syndrome. A patient with monocular morning glory syndrome and reduced visual acuity is reported. The pattern reversal visually evoked potential was reduced and the latency increased in the affected eye.

Microspherophakia.

Microspherophakia is present when the crystalline lens is small and relatively spherical with increased antero-posterior thickness. Clinical findings for a patient with idiopathic bilateral microspherophakia are described. The patient was moderately myopic with slightly reduced visual acuity. The anterior chambers (R: 1.57 and L: 1.37 mm) were shallow compared with normals (3.46 to 3.80 mm) and the crystalline lenses were thicker (R: 4.77 and L: 4.89 mm) than normal (3.3 to 3.96 mm) with steeper than normal anterior (radii of curvature R: 6.2 and L: 6.3 mm) and posterior (R: 6.3 and L: 5.6 mm) surfaces. Microspherophakia may be associated with various syndromes and there is a strong possibility of glaucoma, particularly if the small lens is displaced.
