Article 4 Relative Amblyopia Secondary to Anisometropia in a Patient with Ipsilateral Optic Nerve Hypoplasia
Background: Optic nerve hypoplasia (ONH) is a developmental disorder in which the optic nerve is small and/or there are fewer than normal nerve fibers present. Visual acuity (VA) loss from ONH ranges from none to severe, depending on the extent of macular nerve fiber loss. It is common for patients with decreased vision from unilateral ONH to develop ipsilateral amblyopia secondary to constant ...
متن کاملOptic Nerve Hypoplasia
Congenital anomalies of the optic disc underlie many cases of decreased vision, strabismus, and nystagmus in childhood. A comprehensive evaluation necessitates an understanding of the ophthalmoscopic features, associated neuro-ophthalmologic findings, pathogenesis, and appropriate ancillary studies for each anomaly. The subclassification of different forms of “colobomatous” defects on the basis...
متن کاملSpectrum of optic nerve hypoplasia.
Optic nerve hypoplasia is a non-progressive condition characterised by subnormal vision and a subnormal number of optic nerve axons. It may be unilateral or bilateral, isolated or combined with other defects. Analysis of fundus photographs from a series of 7 patients with a stationary abnormality of different degrees showed that the functional defects could be closely correlated with defects in...
متن کاملHypoplasia of the optic nerve.
Hypoplasia of the optic nerve is uncommon (Scheie and Adler, I94I; Somerville, I962; Whinery and Blodi, I963; Ewald, I967). It is usually due to a failure of development of the ganglion cell layer of the retina and results in a small but discernible optic disc with central vessels. The disc may be cupped with a peripapillary, mottled, yellowish halo corresponding to the size of the normal disc,...
متن کاملUnilateral optic nerve hypoplasia with asymmetric septum: A case report of unilateral septo-optic dysplasia
Septo-optic dysplasia is an uncommon diagnosis comprised in part of a unique composition of congenitalmalformations of the central nervous system. It is defined by three principle findings: optic nerve hypoplasia, absence of the septum pellucidum, and clinical pituitary dysfunction. The syndrome may be associated with various cerebral defects including ectopic posterior pituitary, dysgenesis of...
