We present the first case of an otherwise healthy child with a marked left head tilt used to improve a purely horizontal, nonaccommodative deviation. A patching test confirmed strabismus as the etiology of the abnormal head position. The head tilt was dramatically reduced following bilateral medial rectus recession.

Head tilt can have an impact on the orientation of posterior pole images. We conducted this study to determine the effect of head tilt on image orientation measured by the fovea-Bruch's membrane openi...
To examine whether horizontal head turns while seated or while walking, when instrumented with inertial sensors, were sensitive to the acute effects of concussion and whether horizontal head turns had...
Proper management of a patient with small to moderate horizontal deviations continues to be challenging for the strabismus surgeon. The use of one-muscle surgery for comitant strabismus has been contr...
The purpose of the study is to evaluate if strabismus can be successfully treated requiring less surgical interventions with a Botox-based treatment regimen compared to a purely surgery ba...
Different methods was tried to treat high AC/A strabismus cases;such as prescription of bifocal glasses in esotropia,recession of horizontal muscles with posterior fixation sutures,more re...
The purpose of this study is to determine whether the left lateral tilt-down position, which includes procedures that involve placing patients on their left lateral side at an angle to mak...
Subarachnoid block has become an established and reliable method of providing anaesthesia for lower abdominal and lower limb surgeries. Several factors determine the spread of local anaest...
The strabismus impacts binocular visual acuity and stereoscopy. Thus, driving capacities of patients with strabismus may be reduced. The goal of this work is to study the possible ameliora...
Posture while lying with the head lower than the rest of the body. Extended time in this position is associated with temporary physiologic disturbances.
Misalignment of the visual axes of the eyes. In comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. In noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target. (Miller, Walsh & Hoyt's Clinical Neuro-Ophthalmology, 4th ed, p641)
NEURONS in the inner nuclear layer of the RETINA that synapse with both the RETINAL PHOTORECEPTOR CELLS and the RETINAL BIPOLAR CELLS, as well as other horizontal cells. The horizontal cells modulate the sensory signal.
Diseases of the fourth cranial (trochlear) nerve or its nucleus in the midbrain. The nerve crosses as it exits the midbrain dorsally and may be injured along its course through the intracranial space, cavernous sinus, superior orbital fissure, or orbit. Clinical manifestations include weakness of the superior oblique muscle which causes vertical DIPLOPIA that is maximal when the affected eye is adducted and directed inferiorly. Head tilt may be seen as a compensatory mechanism for diplopia and rotation of the visual axis. Common etiologies include CRANIOCEREBRAL TRAUMA and INFRATENTORIAL NEOPLASMS.
The naturally occurring transmission of genetic information between organisms, related or unrelated, circumventing parent-to-offspring transmission. Horizontal gene transfer may occur via a variety of naturally occurring processes such as GENETIC CONJUGATION; GENETIC TRANSDUCTION; and TRANSFECTION. It may result in a change of the recipient organism's genetic composition (TRANSFORMATION, GENETIC).
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
