FragmentHealth.com » The Eyes » Ectropion eyelid - symptoms

Ectropion - loss of elasticity or control of the eyelid, usually the lower eyelid, that causes it to sag away from the EYE. Ectropion allows tears to overflow the lid rather than remaining in the eye. It also fails to protect the eye, and especially the CORNEA, permitting dryness and exposure to environmental particles that create irritation and possibly injury to the cornea and sclera (“white” of the eye).

Common causes of ectropion include

  • aging
  • damage to the nerves that control the eyelids
  • CICATRICIAL PEMPHIGOID

Symptoms of Ectropion eyelid

Ectropion is a common symptom of BELL’S PALSY, a temporary paralysis of one side of the face that results from INFLAMMATION of the seventh cranial NERVE (facial nerve), and also may accompany neurologic disorders such as PARKINSON’S DISEASE and MULTIPLE SCLEROSIS.

Treatment Ectropion

With ectropion the eye feels irritated and scratchy. Tear production becomes excessive as the eye attempts to lubricate and protect itself, and tears typically run over the lip of the lid and onto the cheeks. The doctor can diagnose ectropion based on its appearance. Treatment is typically surgery to tighten the lid structure to permit the lid to stay against the eye. Whether the ectropion recurs depends on the underlying cause. Untreated ectropion may result in extensive damage to the surface of the eye and cornea, including INFECTION, that interferes with vision and the health of the eye.

Eye (human) - definition and function

The Eyes |

Eye is the organ of vision. The paired eyes work in coordination to present NERVE impulses the BRAIN interprets as dimensional (stereovisual) images. The function of sight requires close integration among the structures of the eye, the neurologic system, and the muscular system. Each eye is a fluidfilled, elongated globe of fibrous tissue, about 1⁄4

Xanthelasma - definition and removal

The Eyes |

Xanthelasma - deposits of fatty plaque that form blisterlike lesions on the eyelids, usually the upper eyelids near the corner of the NOSE. The lesions are yellowish in color and often indicate HYPERLIPIDEMIA (elevated BLOOD levels of cholesterol and triglycerides). Though harmless, the lesions can cause the eyelid to droop, obscuring vision when an upper

Vitreous Detachment - definition, causes and treatment

The Eyes |

Vitreous Detachment - the separation of the vitreous humor, the gelatinous substance within the EYE, from the RETINA. Vitreous detachment commonly occurs with advancing age as the vitreous humor thins and takes on more of a liquid consistency. By itself vitreous detachment is harmless and has no effect on vision, though it typically produces FLOATERS

Retina - definition, function and diseases

The Eyes |

Retina - the innermost layer of the EYE. The retina receives light images and converts them to NERVE impulses the OPTIC NERVE conveys to the BRAIN. The retina is two tissue-thin layers that together are less than 1⁄2 millimeter in thickness. The outer pigment layer provides a completely light-absorbing, nonreflective lining. The inner sensory layer

Visual Acuity - definition

The Eyes |

Visual Acuity - the ability to see objects clearly and sharply. Visual acuity assesses central vision and represents the function of the CORNEA, iris (pupil size), LENS, and RETINA. The SNELLEN CHART, which presents lines of letters of diminishing size, is the standard measure of visual acuity. Environmental factors that influence visual acuity include

Visual Field - definition and tests

The Eyes |

Visual Field - the total area or scope of vision. EYE care specialists map the visual field by measuring the boundaries of peripheral vision in degrees from the point of central vision. A normal field of vision is 135 degrees vertically (60 degrees up and 75 degrees down) and 160 degrees horizontally (100 degrees outward and 60 degrees inward). Everyone has

Vitrectomy - eye surgery

The Eyes |

Vitrectomy - an OPERATION to remove the vitreous humor from within the EYE as treatment for RETINAL DETACHMENT, vitreous HEMORRHAGE (bleeding into the vitreous humor), RETINOPATHY, and foreign body penetration. In vitrectomy, the ophthalmologist makes three tiny incisions in the sclera (white portion) of the eye for the insertion of a cutting instrument, a

Vision Health - definition

The Eyes |

Vision Health - personal care for the eyes to protect the eyes and preserve vision. The two most important elements of vision health are EYE protection and regular ophthalmic examinations. Vision Health and Protective Eyewear Most injuries to the eyes are preventable by wearing appropriate protective eyewear, which ranges from sunglasses to protect the

Vision Impairment - symptoms and treatment

The Eyes |

Vision Impairment Definition Vision Impairment - the uncorrectable loss of vision. About 12 million Americans have vision impairments that prevent them from participating in occupations and activities that have requirements or legal standards for VISUAL ACUITY (the ability to see clearly) and VISUAL FIELD (the scope of peripheral vision). People who have

Uveitis - symptoms and treatment

The Eyes |

Uveitis - INFLAMMATION of the uveal structures of the EYE, which include the iris, ciliary body, and choroid. Uveitis most commonly affects the front of the eye (anterior uveitis) though may involve specific segments of the eye or the uveal tract throughout the eye (diffuse uveitis). Symptoms of Uveitis Symptoms can vary from mild to severe and may
