  2. Recurrent corneal erosion - Wikipedia

    en.wikipedia.org/wiki/Recurrent_corneal_erosion

    Recurrent corneal erosion (RCE) is a disorder of the eyes characterized by the failure of the cornea's outermost layer of epithelial cells to attach to the underlying basement membrane (Bowman's layer). The condition is excruciatingly painful because the loss of these cells results in the exposure of sensitive corneal nerves.

  3. Corneal abrasion - Wikipedia

    en.wikipedia.org/wiki/Corneal_abrasion

    Signs and symptoms of corneal abrasion include pain, trouble with bright lights, a foreign-body sensation, excessive squinting, and reflex production of tears. Signs include epithelial defects and edema, and often redness of the eye. The vision may be blurred, both from any swelling of the cornea and from excess tears.

  4. Fluorescein (medical use) - Wikipedia

    en.wikipedia.org/wiki/Fluorescein_(medical_use)

    Fluorescein is a dye which is taken up by damaged cornea such that the area appears green under cobalt blue light. [3] There is also a version that comes premixed with lidocaine. [4] [8] Fluorescein was first made in 1871. [9] It is on the World Health Organization's List of Essential Medicines. [10]

  5. Dry eye syndrome - Wikipedia

    en.wikipedia.org/wiki/Dry_eye_syndrome

    Diagnosis is mostly based on the symptoms, though several other tests may be used. [8] Dry eye syndrome occasionally makes wearing contact lenses impossible. [2] Treatment depends on the underlying cause. Artificial tears are usually the first line of treatment. Wrap-around glasses that fit close to the face may decrease tear evaporation. [9]

  6. Lattice corneal dystrophy - Wikipedia

    en.wikipedia.org/wiki/Lattice_corneal_dystrophy

    In case of corneal erosion, a doctor may prescribe eye drops and ointments to reduce the friction on the eroded cornea. In some cases, an eye patch may be used to immobilize the eyelids. With effective care, these erosions usually heal within three to seven days, although occasional sensations of pain may occur for the next six-to-eight weeks.

  7. Corneal ulcer - Wikipedia

    en.wikipedia.org/wiki/Corneal_ulcer

    Corneal ulcer, also called keratitis, is an inflammatory or, more seriously, infective condition of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma. [ 1 ] [ 2 ] [ 3 ] It is a common condition in humans particularly in the tropics and in farming. [ 4 ]

  8. Pseudoexfoliation syndrome - Wikipedia

    en.wikipedia.org/wiki/Pseudoexfoliation_syndrome

    The blockage leads to greater-than-normal elevated intraocular pressure [2] which, in turn, can damage the optic nerve. [7] The eye produces a clear fluid called the aqueous humor which subsequently drains such that there is a constant level of safe pressure within the eye, but glaucoma can result if this normal outflow of fluid is blocked.

  9. Ocular neuropathic pain - Wikipedia

    en.wikipedia.org/wiki/Ocular_neuropathic_pain

    Ocular neuropathic pain, also called corneal neuralgia, is a spectrum of disorders of ocular pain which are caused by damage or disease affecting the nerves. Ocular neuropathic pain is frequently associated with damaged or dysfunctional corneal nerves, [ 1 ] but the condition can also be caused by peripheral or centralized sensitization. [ 2 ]
