A healthcare provider can usually diagnose a port-wine stain based entirely upon the history and appearance. In unusual cases, a skin biopsy may be needed to confirm the diagnosis. Depending on the location of the birthmark and other associated symptoms, a physician may choose to order a measurement of intraocular pressure or X-ray of the skull.

A MRI scan of the brain may be performed (under anesthesia) on infants who have a port-wine stain in the head area in order to check for signs of Sturge-Weber syndrome.

If the port-wine stain is inside the mouth, a provider may check the insides of a newborn baby's throat with a scope to see if there are any changes (growths) other than just the color.

If the port-wine stain is around the eye or on the eyelid, a referral may be made to an optometrist or ophthalmologist for a test of the ocular pressures in that eye. If swelling occurs in the port-wine stain, it may cause vision problems, glaucoma, or blindness.

Due to the different underlying causes, proper diagnosis, treatment, and prognosis can only be determined by an eye care professional. Punctate epithelial erosions may be treated with artificial tears. In some disorders, topical antibiotic is added to the treatment. Patients should discontinue contact lens wear until recovery.

Treatment is a relatively simple surgery in which excess skin of the outer lids is removed or tendons and muscles are shortened with one or two stitches. General anesthesia is sometimes used before local anesthetics are injected into the muscles around the eye. Prognosis is excellent if surgery is performed before the cornea is damaged.

Conjunctival concretions can be seen easily by everting the eyelid. The projecting concretions should be removed. Removal is easily performed by a doctor. For example, using needles or sharp knife removes the concretion, under a local light anesthesia of the conjunctiva.

If dermatochalasis is severe enough to obstruct the peripheral or superior visual fields, then it may be treated with a surgical procedure called blepharoplasty. In blepharoplasty surgery, excess skin, muscle and fat are removed. While the improvement of vision is an indication for blepharoplasty on the superior eyelid, if the visual fields are not obstructed, it may be performed for cosmetic reasons. In general, blepharoplasty of the inferior eyelid is considered cosmetic, as dermatochalasis in the lower eyelid does not interfere with vision.

Treatment of lagopthalmos can include both supportive care methods as well as surgical. If unable to receive surgery, artificial tears should be administered at least four times a day to the cornea to preserve the tear film. Leading up to a surgery, a patient can undergo a tarsorrhaphy which partially sews the eye shut temporarily to further protect the cornea as the patient waits for care. Multiple surgical treatments exist for Lagopthalmos but the most prevalent method includes weighing the upper eyelid down by surgically inserting a gold plate. Due to possible complications in conjunction with both the upper and lower eyelid, it might also be required to undergo a second surgery to tighten and elevate the lower eyelid to ensure both the upper and lower eyelids can fully close and protect the cornea.

Dermatochalasis commonly affects the elderly, although sometimes it is congenitally acquired. The elderly version may begin to develop as early as 40 years of age, and it continues to progress with age. The congenital version may begin around 20 years of age. There is no racial predisposition towards developing dermatochalasis, and men and women are equally affected.

The main treatment is symptomatic, since the underlying genetic defect cannot be corrected as of 2015. Symptomatic treatment is surgical.

A surgeon trained to do eyelid surgery, such as a plastic surgeon or ophthalmologist, is required to decide and perform the appropriate surgical procedure. The following procedures have been described for blepharochalasis:

- External levator aponeurosis tuck

- Blepharoplasty

- Lateral canthoplasty

- Dermis fat grafts

These are used to correct atrophic blepharochalasis after the syndrome has run its course.

A symblepharon is a partial or complete adhesion of the palpebral conjunctiva of the eyelid to the bulbar conjunctiva of the eyeball. It results either from disease (conjunctival sequelae of trachoma) or trauma. Cicatricial pemphigoid and, in severe cases, rosacea may cause symblepharon. It is rarely congenital. and its treament

Aponeurotic and congenital ptosis may require surgical correction if severe enough to interfere with vision or if cosmetics is a concern.

Treatment depends on the type of ptosis and is usually performed by an ophthalmic plastic and reconstructive surgeon, specializing in diseases and problems of the eyelid.

Surgical procedures include:

- Levator resection

- Müller muscle resection

- Frontalis sling operation (preferred option for oculopharyngeal muscular dystrophy)

Non-surgical modalities like the use of "crutch" glasses or Ptosis crutches or special scleral contact lenses to support the eyelid may also be used.

Ptosis that is caused by a disease may improve if the disease is treated successfully, although some related diseases, such as oculopharyngeal muscular dystrophy currently have no treatments or cures.

The most obvious, and often important part of treatment, is avoiding exposure to sunlight. This includes wearing protective clothing and using sunscreen (physical and chemical). Keratosis can also be treated using cryotherapy or fluorouracil. Theoretically, the condition could be completely corrected if functionally intact (non-mutated) endonuclease genes could be inserted into every cell into the body, and the most promising method to do this would be crispr. However, every cell in the body would have to be penetrated for a total cure, because the skin does not protect against other forms of radiation, like x-rays, even at low quantities harmless for those without xeroderma pigmentosa.

In the absence of successful treatment, hypertrophy (increased tissue mass) of the stains may cause problems later in life, such as loss of function (especially if the stain is near the eye or mouth), bleeding, and increasing disfigurement. Lesions on or near the eyelid can be associated with glaucoma. If the port-wine stain is on the face or other highly visible part of the body, its presence can also cause emotional and social problems for the affected person.

It is suggested that gene therapy might be used as a cure in the future.

Entropion has been documented in most dog breeds, although there are some breeds (particularly purebreds) that are more commonly affected than others. These include the Akita, Pug, Chow Chow, Shar Pei, St. Bernard, Cocker Spaniel, Boxer, English Springer Spaniel, Welsh Springer Spaniel, Labrador Retriever, Cavalier King Charles Spaniel, Neapolitan Mastiff, Bull Mastiff, Great Dane, Irish Setter, Shiba Inu, Rottweiler, Poodle and particularly Bloodhound. The condition is usually present by six months of age. If left untreated, the condition can cause such trauma to the eye that it will require removal.

Entropion has also been seen in cat breeds. Typically it is secondary to trauma, or infection leading to chronic eyelid changes. It is also seen secondary to enophthalmos. Congenital cases are also seen with the brachicephalic breeds being over represented.

Upper lid entropion involves the eyelashes rubbing on the eye, but the lower lid usually has no eyelashes, so little or no hair rubs on the eye. Surgical correction is used in more severe cases. A number of techniques for surgical correction exist. The Hotz-Celsus technique involves the removal of strip of skin and orbicularis oculi muscle parallel to the affected portion of the lid and then the skin is sutured.

Alternative techniques such as the Wyman technique focus on tightening the lower eyelid, this technique is not as effective in cases of enophthalmos.

Shar Peis, who often are affected as young as two or three weeks old, respond well to temporary eyelid tacking. The entropion is often corrected after three to four weeks, and the sutures are removed.

Nocturnal lagophthalmos is the inability to close the eyelids during sleep. It may reduce the quality of sleep, cause exposure-related symptoms or, if severe, cause corneal damage (exposure keratopathy). The degree of lagophthalmos can be minor (obscure lagophthalmos), or quite obvious.

It is often caused by an anomaly of the eyelid that prevents full closure. Treatment may involve surgery to correct the malposition of the eyelid(s). Punctal plugs may be used to increase the amount of lubrication on the surface of the eyeball by blocking some of the tear drainage ducts. Eye drops may also be used to provide additional lubrication or encourage the eyes to increase tear production.

The condition is not widely understood; in at least one instance a passenger was removed from a US Airways flight because of it.

BPES is very rare: only 50-100 cases have been described. It affects slightly more males than females.

In all forms of blepharitis, Optometrists or Ophthalmologists examine the tear film, which is the most efficient method in determining instability. The most frequently used method is to measure tear production via tear break-up time (TBUT), which calculates the duration interval between complete blinks. This serves as a primary indication of regional dryness in the pre-corneal tear film after fluorescein injections. If TBUT is shorter than 10 seconds, then this suggests instability.

Staphylococcal blepharitis is diagnosed by examining erythema and edema of the eyelid margin. Patients may exhibit alopecia areata of eyelashes and/or growth misdirection, trichiasis. Other signs may include telangiectasia on the anterior eyelid, collarettes encircling the lash base, and corneal changes. Seborrheic blepharitis is distinguished by less erythema, edema, and telangiectasia of the eyelid margins. Posterior blepharitis and Meibomian Gland Dysfunction are frequently associated with rosacea and can be seen during an ocular examination of the posterior eyelid margin. The meibomian glands may appear caked with oil or visibly obstructed.

Cultures of the eyelid margins can be a clear indicator for patients suffering from recurrent anterior blepharitis with severe inflammation, in addition to patients who are not responding to therapy. Measurements of tear osmolarity may be beneficial in diagnosing concurrent dry eye syndrome (DES), which may be responsible for overlapping symptoms and would allow the physician to decipher between conditions and move forward with the most beneficial protocol for the patient. Consequently, the measurement of tear osmolarity has various limitations in differentiating between aqueous deficiencies and evaporative dry eye. Microscopic evaluation of epilated eyelashes may reveal mites, which have been evident in cases of chronic blepharoconjunctivitis. A biopsy of the eyelid can also determine the exclusion of carcinoma, therapy resistance, or unifocal recurrent chalazia.

Previously, treatment was thought optional until the role of NM was fully understood. The NM gland is responsible for 40–50% of tear production. If exposed for extended periods of time, the gland is at risk for trauma, secondary infection, and reduced tear production. Many complications can arise if left untreated: early closed-eye massage manipulation is recommended to prevent inflammation .

Ectropion in dogs usually involves the lower eyelid. Often the condition has no symptoms, but tearing and conjunctivitis may be seen. Breeds associated with ectropion include the Cocker Spaniel, the Saint Bernard, the Bloodhound, the Clumber Spaniel, and the Basset Hound. It can also result from trauma or nerve damage. Treatment (surgery) is recommended only if there is chronic conjunctivitis or if there is corneal damage. A small part of the affected lid is removed and then the lid is sewn back together.

The main diagnosis technique is observing the area. Then blood tests can be done to determine if there is a pre-existing condition. Family history can be considered because some of the related causes/conditions can be inherited.

Fewer than 40% of individuals with the disease survive beyond the age of 20. Some XP victims with less severe cases do manage to live well into their 40s.

It is encountered more commonly in younger rather than older individuals.

An ectopic cilia is a special type of distichia. It is usually found in younger dogs. Commonly affected breeds include Poodles, Golden Retrievers, and Shih Tzus. The eyelash exits through the conjunctiva of the eyelid facing toward the eye, usually at the middle of the upper eyelid. It can cause intense pain and corneal ulcers. Treatment is surgery or cryotherapy.

Cherry eye, if caught early, can be resolved with a downward diagonal-toward-snout closed-eye massage of the affected eye or occasionally self-corrects alone or with antibiotics and steroids. Sometimes the prolapse will correct itself with no interference, or with slight physical manual massage manipulation as often as necessary coupled with medication.
