If instead of the actual head tilt (as compared to true vertical), the direction of the head tilt as interpreted by the brain (subjective head tilt) is given importance, then it is seen that the head tilt and ocular torsion are actually in the same direction in both the physiologic ocular counter-roll and the pathologic ocular tilt reaction.
The canthus (pl.: canthi, palpebral commissures) is either corner of the eye where the upper and lower eyelids meet. [1] More specifically, the inner and outer canthi are, respectively, the medial and lateral ends/angles of the palpebral fissure.
The most common cause of elevated intraocular pressure is orbital compartment syndrome (OCS) caused by trauma, retrobulbar hemorrhage, infections, tumors, or prolonged hypoxemia. [3] Absolute contraindications to canthotomy include globe rupture. Complications include bleeding, infections, cosmetic deformities, and functional impairment of ...

The spherical aberration of the cornea is usually positive whereas the young crystalline lens exhibits a negative spherical aberration. Besides, there is strong evidence of compensation for aberrations between the cornea and intraocular optics in cases of astigmatism (horizontal/vertical) and horizontal coma.

Skew deviation is an unusual ocular deviation (), wherein the eyes move upward (hypertropia) in opposite directions.Skew deviation is caused by abnormal prenuclear vestibular input to the ocular motor nuclei, most commonly due to brainstem or cerebellar stroke.
Dementia is a complicated condition, and researchers are still unpacking a lot about its underlying causes. However, there are some things doctors generally agree on when it comes to prevention.
