Crouzon Syndrome: Relationship of Eye Movements to Pattern Strabismus.
PURPOSE To characterize conjugate eye movements in Crouzon syndrome (CS) patients with and without strabismus. METHODS Smooth pursuit, saccades, horizontal optokinetic nystagmus (OKN), and horizontal vestibulo-ocular reflex (VOR) were recorded using binocular video-oculography (VOG) in 10 children with CS (5 orthotropic, 5 strabismic) and 12 age-matched controls. Hess-Lancaster plots were gen...
متن کاملEye Movements, Strabismus, Amblyopia, and Neuro-Ophthalmology Directional Asymmetries in Human Smooth Pursuit Eye Movements
Citation: Ke SR, Lam J, Pai DK, Spering M. Directional asymmetries in human smooth pursuit eye movements. Invest Ophthalmol Vis Sci. 2013;54:4409–4421. DOI:10.1167/iovs.12-11369 PURPOSE. Humans make smooth pursuit eye movements to bring the image of a moving object onto the fovea. Although pursuit accuracy is critical to prevent motion blur, the eye often falls behind the target. Previous studi...
متن کاملSurgical Treatment of V-pattern Exotropia in Crouzon Syndrome.
PURPOSE Strabismus affects as many as 60% to 70% of patients with Crouzon syndrome. V-pattern strabismus is common and is thought to be secondary to severe oblique muscle dysfunction. The complex motility disorders produced by abnormal extraocular muscles in this syndrome can be difficult to manage. Few studies have reported findings regarding the extraocular muscles or how to plan and adapt th...
متن کاملDynamic vergence eye movements in strabismus and amblyopia: symmetric vergence.
Dynamic vergence eye movements in response to step target displacements along the midline were measured by an infrared reflection technique in 11 patients having either intermittent strabismus, constants-strabismus amblyopia, or amblyopia without strabismus. We found the absence of normal disparity (fusional) vergence in all patients having strabismus and in some patients having amblyopia witho...
متن کاملDynamic vergence eye movements in strabismus and amblyopia: asymmetric vergence.
This report investigates line-of-sight asymmetric disparity vergence in patients having either intermittent strabismus, constant strabismus with amblyopia, or amblyopia without strabismus. We find an absence of disparity vergence in all patients with strabismus and in some with amblyopia only. Accommodative vergence and saccades place the dominant eye on the targets moving in depth. These accom...
