  2. Leukocoria - Wikipedia

    en.wikipedia.org/wiki/Leukocoria

    Leukocoria (also white pupillary reflex) is an abnormal white reflection from the retina of the eye. Leukocoria resembles eyeshine , but leukocoria can also occur in animals that lack eyeshine because their retina lacks a tapetum lucidum .

  3. Swinging light test - Wikipedia

    en.wikipedia.org/wiki/Swinging_light_test

    For an adequate test, vision must not be entirely lost. In dim room light, the examiner notes the size of the pupils. The patient is asked to gaze into the distance, and the examiner swings the beam of a penlight back and forth from one pupil to the other, and observes the size of pupils and reaction in the eye that is lit.

  4. Relative afferent pupillary defect - Wikipedia

    en.wikipedia.org/wiki/Relative_afferent...

    The Marcus Gunn pupil is a relative afferent pupillary defect indicating a decreased pupillary response to light in the affected eye. [3] In the swinging flashlight test, a light is alternately shone into the left and right eyes. A normal response would be equal constriction of both pupils, regardless of which eye the light is directed at.

  5. Childhood cataract - Wikipedia

    en.wikipedia.org/wiki/Childhood_cataract

    A complete physical examination is done to identify if a child has any associated systemic symptoms which may aid in a diagnosis of childhood cataracts. [4] In addition, a complete eye examination is done. [2] [4] This eye exam includes fixation, pupillary reflex test, and test for visual acuity. [4]

  6. Neurological pupil index - Wikipedia

    en.wikipedia.org/wiki/Neurological_Pupil_Index

    The Neurological Pupil index, or NPi, is an algorithm developed by NeurOptics, Inc., that removes subjectivity from the pupillary evaluation. A patient's pupil measurement (including variables such as size, latency, constriction velocity, dilation velocity, etc.) is obtained using a pupillometer, and the measurement is compared against a normative model of pupil reaction to light and ...

  7. Seasonal hyperacute panuveitis - Wikipedia

    en.wikipedia.org/wiki/Seasonal_hyperacute_panuveitis

    Whitening of the pupil, due to massive exhudation into the vitreous, is typical, leading to the hallmark "white pupil in a red eye". [1] Visual loss is rapid, taking hours or, at most, few days – two-thirds of the patients are already blind in the affected eye when presenting. [5] Intraocular pressure plummets, eventually causing phthisis ...

  8. Pupillary reflex - Wikipedia

    en.wikipedia.org/wiki/Pupillary_reflex

    The pupillary reflex results in the pupil constricting (left) and dilating (right) These include the pupillary light reflex and accommodation reflex . Although the pupillary response , in which the pupil dilates or constricts due to light is not usually called a "reflex", it is still usually considered a part of this topic.

  9. Visual pathway lesions - Wikipedia

    en.wikipedia.org/wiki/Visual_pathway_lesions

    Careful clinical assessment could aid in accurate diagnosis of the cause of the visual field defect and loss of vision. Compressive lesions of the visual pathway, especially lesions affecting optic nerve require a multi-disciplinary approach involving neurosurgeon , physician as well as the ophthalmologist . [ 32 ]
