  • Ectropion
    Ectropion is a medical condition in which the lower eyelid turns outwards.
  • Chalazion
    Chalazion is a cyst in the eyelid due to a blocked oil gland.
  • Exophthalmos
    Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit.
  • Ptosis (eyelid)
    Ptosis is a drooping or falling of the upper eyelid.
  • Orbital cellulitis
    Orbital cellulitis is inflammation of eye tissues behind the orbital septum.
  • Trichiasis
    Trichiasis is a medical term for abnormally positioned eyelashes that grow back toward the eye, touching the cornea or conjunctiva.
  • Blepharochalasis
    Blepharochalasis is an inflammation of the eyelid that is characterized by exacerbations and remissions of eyelid edema, which results in a stretching and subsequent atrophy of the eyelid tissue, leading to the formation of redundant folds over the lid margins.
  • Entropion
    Entropion is a medical condition in which the eyelid (usually the lower lid) folds inward.
  • Enophthalmos
    Enophthalmos is the posterior displacement of the eyeball within the orbit due to changes in the volume of the orbit (bone) relative to its contents (the eyeball and orbital fat), or loss of function of the orbitalis muscle.
  • Dacryoadenitis
    Dacryoadenitis is inflammation of the lacrimal glands (the tear-producing glands).
  • Xanthelasma
    Xanthelasma (or xanthelasma palpebrarum; pronunciation: /ˌzænθᵻˈlæzmə/) is a sharply demarcated yellowish deposit of fat underneath the skin, usually on or around the eyelids.
  • Orbital lymphoma
    Orbital lymphoma is a common type of non-Hodgkin lymphoma that occurs near or on the eye.
  • Stye
    Stye, also known as hordeolum, is an infection of an oil gland in the eyelid.
  • Nasolacrimal duct obstruction
    Nasolacrimal duct obstruction (NLDO) is the obstruction of nasolacrimal duct and may be either congenital or acquired.
  • Blepharitis
    Blepharitis (/blɛfərˈaɪtᵻs/ BLEF-ər-EYE-tis) is a common eye condition characterized by chronic inflammation of the eyelid, usually where eyelashes grow, resulting in inflamed, irritated, itchy, and reddened eyelids.
  • Blepharophimosis
    Blepharophimosis is a condition where the patient has bilateral ptosis with reduced lid size, vertically and horizontally.
  • Blepharospasm
    Blepharospasm is any abnormal contraction or twitch of the eyelid.
  • Lagophthalmos
    Lagophthalmos is defined as the inability to close the eyelids completely.
  • Dacryocystitis
    Dacryocystitis is an infection of the lacrimal sac, secondary to obstruction of the nasolacrimal duct at the junction of lacrimal sac.
