Hypotropic Dissociated Vertical Deviation; a Case Report
نویسندگان
چکیده
PURPOSE To report the clinical features of a rare case of hypotropic dissociated vertical deviation (DVD). CASE REPORT A 25-year-old female was referred with unilateral esotropia, hypotropia and slow variable downward drift in her left eye. She had history of esotropia since she had been 3-4 months of age. Best corrected visual acuity was 20/20 in her right eye and 20/40 in the left one when hyperopia was corrected. She underwent bimedial rectus muscle recession of 5.25mm for 45 prism diopters (PDs) of esotropia. She was orthophoric 3 months after surgery and no further operation was planned for correction of the hypotropic DVD. CONCLUSION This rare case of hypotropic DVD showed only mild amblyopia in her non-fixating eye. The etiology was most probably acquired considering hyperopia as a sign of early onset accommodative esotropia.

Static ocular counterroll reflex in skew deviation.
OBJECTIVE The static ocular counterroll (OCR) reflex generates partially compensatory torsional eye movements during head roll. It is mediated by the utricle in the inner ear. Skew deviation is a vertical strabismus thought to be caused by imbalance in the utriculo-ocular pathway. We hypothesized that if skew deviation is indeed caused by damage to this reflex pathway, patients with skew deviat...

A 50-year-old man was admitted for the acute onset of vertical diplopia worse on left gaze. The right eye appeared hypertropic. Either right fourth nerve palsy or skew deviation was possible.1,2 Nonmydriatic retinal photography revealed an excyclotorsion of the hypotropic eye associated with incyclotorsion of the hypertropic eye (figure 1, A and B) providing a key element for skew deviation. In...

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...
متن کاملDissociated vertical deviation: evidence of abnormal visual pathway projection.
Abnormalities in visually evoked responses have been used to demonstrate abnormal optic nerve fibre projections in human albinos, who have anomalous nystagmoid movements. Using visually evoked potentials we tested the hypothesis that patients with dissociated vertical deviation (another group with anomalous nystagmoid movements) may have abnormal visual evoked responses similar to those of albi...

Flash visually evoked cortical potentials have been recorded in three groups of age- and sex-matched subjects; one comprised of subjects with dissociated vertical deviation, one comprised of subjects with oculocutaneous albinism and one group of controls. The latency of the major positive (P2) component did not show statistically significant contralateral lateralization on monocular stimulation...
