2005年2月21日 · See-Saw Nystagmus . The first case reported of see-saw nystagmus was in 1913 by Maddox (1913). See-saw nystagmus (SSN) is a rare ocular presentation with less than 50 cases reported in the literature.

2011年8月30日 · For infants with bilateral optic nerve hypoplasia, they commonly present with a course, pendular nystagmus.[2,3] The classic finding in patients with optic nerve hypopasia is a decreased diameter of the optic disc.

The nystagmus characteristics will then be compared with the etiology as determined by the clinical workup for correlation. Results: Thus far, our study has enrolled 40 patients: 22 males and 18 females between the ages of 4 and 18. Nystagmus recordings were …

2024年1月29日 · Given the patient’s complete iris TID’s, nystagmus, and poor foveal reflex, oculocutaneous albinism was thought to be the most likely diagnosis. An albinism panel was obtained which showed no mutations found in any OCA gene. 3 months later, she was seen in clinic for a repeat vision check and retinoscopy given her relatively high myopia.

2024年1月22日 · Presenting signs include decreased vision, strabismus, nystagmus, and/or leukocoria. Visual acuity in the MGDA eye is usually poor. One study of 12 MGDA eyes found a median best-corrected visual acuity of 20/300 (range 20/30 - hand motion) [2]. Strabismus (eso- or exodeviation are most common) may be present in up to 70% of eyes affected by ...
