  2. Esotropia - Wikipedia

    en.wikipedia.org/wiki/Esotropia

    Esotropia (from Greek eso 'inward' and trope 'a turning' [1]) is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [2]

  3. Strabismus - Wikipedia

    en.wikipedia.org/wiki/Strabismus

    Impairment of cranial nerve IV, which can be congenital, causes the associated eye to drift up and perhaps slightly inward. Sixth nerve palsy causes the associated eye to deviate inward and has many causes due to the relatively long path of the nerve. Increased cranial pressure can compress the nerve as it runs between the clivus and brain stem.

  4. Infantile esotropia - Wikipedia

    en.wikipedia.org/wiki/Infantile_esotropia

    Infantile esotropia is an ocular condition of early onset in which one or either eye turns inward. It is a specific sub-type of esotropia and has been a subject of much debate amongst ophthalmologists with regard to its naming, diagnostic features, and treatment.

  5. Sixth nerve palsy - Wikipedia

    en.wikipedia.org/wiki/Sixth_nerve_palsy

    Sixth nerve palsy causes the eyes to deviate inward (see: Pathophysiology of strabismus). Vallee et al. [ 6 ] report that benign and rapidly recovering isolated VIth nerve palsy can occur in childhood, sometimes precipitated by ear, nose and throat infections.

  6. Exotropia - Wikipedia

    en.wikipedia.org/wiki/Exotropia

    When one eye turns inward, outward, upward, or downward, two different pictures are sent to the brain. Thus, the brain can no longer fuse the two images coming from the two eyes. This causes loss of depth perception and binocular vision. The term is from Greek exo meaning "outward" and trope meaning "a turning". [1]

  7. Trachoma - Wikipedia

    en.wikipedia.org/wiki/Trachoma

    The infection causes a roughening of the inner surface of the eyelids. [2] This roughening can lead to pain in the eyes, breakdown of the outer surface or cornea of the eyes, and eventual blindness. [2] Untreated, repeated trachoma infections can result in a form of permanent blindness when the eyelids turn inward. [2]

  8. Dissociated vertical deviation - Wikipedia

    en.wikipedia.org/wiki/Dissociated_vertical_deviation

    Usually both eyes work together as described by Hering's and Sherrington's laws of innervation. A DVD is a slow upward and sometimes temporal movement of one eye, with cortical suppression of the vision in that eye while it is deviated. On returning downward and possibly inward to take up fixation, the DVD slow movement will be reversed. [2]

  9. Entropion - Wikipedia

    en.wikipedia.org/wiki/Entropion

    The upper or lower eyelid can be involved, and one or both eyes may be affected. When entropion occurs in both eyes, this is known as "bilateral entropion". Repeated cases of trachoma infection may cause scarring of the inner eyelid, which may cause entropion. [3] In human cases, this condition is most common to people over 60 years of age. [4]
