Superior segmental optic nerve hypoplasia was also associated with glaucoma in one eye of a bilateral NOH case and the NOH eye of a unilateral NOH patient. Ocular manifestations including refractive errors, size, and appearances of the optic discs, retinal nerve fiber thickness (NFLT) ascertained by optical coherence tomography (OCT), and VFD were examined.Results: Ophthalmic examinations revealing NOH showed high myopia at more than -5.0D, a small disc with nasal double-ring appearance, significantly decreased NFLT by OCT, and retinal nerve fiber layer defect in the corresponding nasal sector. Stationary temporal VFD varied from a slight depression of the peripheral isopters to wide sector defects. In contrast, two glaucoma patients with NOH-like temporal VFD showed several different clinical features, including mild myopia less than -5D, a normal size with glaucomatous disc cupping; a slight decrease in nasal NFLT and progression of temporal and other glaucomatous VFD.Conclusion: Careful evaluation of optic disc appearance and measurement of NFLT using OCT may help to distinguish between NOH and glaucoma with NOH-like temporal VFD.Keywords: nasal optic disc hypoplasia, glaucoma, temporal visual field defects, optical coherence tomography, superior segmental optic nerve hypoplasia Hiroshi OhguroIkuyo OhguroMidori Tsurutaet alDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2010, Iss default, Pp 547-555 (2010)
