DOS Times Vol. 12, No. 3 September, 2006 Dissociated Vertical Deviation (DVD) is one of the least understood forms of strabismus. It was first described by Stevens as double vertical strabismus, other common names given to this anomaly are, Alternating hyperphoria (Crone), Anaphoria / anatropia (Stevens), Periodic vertical squint (Anderson), Strabismus sursoadductorius (Cords). The term "Dissoc...

PURPOSE To compare the surgical results of adjustable and non-adjustable horizontal strabismus surgery for concomitant horizontal strabismus. METHODS The charts of 231 patients, who underwent horizontal strabismus surgery, selected using probabilistic sampling, were retrospectively reviewed. Patients were divided into two groups according to the surgical technique used and strabismus type. Th...

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...

Strabismus is a frequent ocular disorder that develops early in life in humans. As a general rule, it is characterized by a misalignment of the visual axes which most often appears during the critical period of visual development. However other characteristics of strabismus may vary greatly among subjects, for example, being convergent or divergent, horizontal or vertical, with variable angles ...

Vision is important for postural control as is shown by the Romberg quotient (RQ): with eyes closed, postural instability increases relative to eyes open (RQ = 2). Yet while fixating at far distance, postural stability is similar with eyes open and eyes closed (RQ = 1). Postural stability can be better with both eyes viewing than one eye, but such effect is not consistent among healthy subjects...
