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.
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.

A punctal plug may be inserted into the tear duct by an optometrist or ophthalmologist, decreasing the removal of natural tears from the affected eye.
The use of contact lenses may help prevent the abrasion during blinking lifting off the surface layer and uses thin lenses that are gas permeable to minimise reduced oxygenation. However they need to be used for between 8–26 weeks and such persistent use both incurs frequent follow-up visits and may increase the risk of infections.
Alternatively, under local anaesthetic, the corneal layer may be gently removed with a fine needle, cauterised (heat or laser) or 'spot welding' attempted (again with lasers). The procedures are not guaranteed to work, and in a minority may exacerbate the problem.
Anterior Stromal Puncture with a 20-25 gauge needle is an effective and simple treatment.
An option for minimally invasive and long-term effective therapy is laser phototherapeutic keratectomy. Laser PTK involves the surgical laser treatment of the cornea to selectively ablate cells on the surface layer of the cornea. It is thought that the natural regrowth of cells in the following days are better able to attach to the basement membrane to prevent recurrence of the condition. Laser PTK has been found to be most effective after epithelial debridement for the partial ablation of Bowman's lamella, which performed prior to PTK in the surgical procedure. This is meant to smoothen out the corneal area that the laser PTK will then treat. In some cases, small-spot PTK, which only treats certain areas of the cornea may also be an acceptable alternative.
With the eye generally profusely watering, the type of tears being produced have little adhesive property. Water or saline eye drops tend therefore to be ineffective. Rather a 'better quality' of tear is required with higher 'wetting ability' (i.e. greater amount of glycoproteins) and so artificial tears (e.g. viscotears) are applied frequently. Also recommended is Muro 128 5% Ointment (Sodium Chloride Hypertonicity Ophthalmic Ointment, 5%) which is a great relief overnight, it lasts longer than most regular tears and provides protection for those with severe cases.
Nocturnal Lagophthalmos (where one’s eyelids don’t close enough to cover the eye completely during sleep) may be an exacerbating factor, in which case using surgical tape to keep the eye closed at night can help.
Whilst individual episodes may settle within a few hours or days, additional episodes (as the name suggests) will recur at intervals.
Where episodes frequently occur, or there is an underlying disorder, one medical, or three types of surgical curative procedures may be attempted:
use of therapeutic contact lens, controlled puncturing of the surface layer of the eye (Anterior Stromal Puncture) and laser phototherapeutic keratectomy (PTK). These all essentially try to allow the surface epithelium to reestablish with normal binding to the underlying basement membrane, the method chosen depends upon the location & size of the erosion.
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.
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.
Some of the adverse outcomes associated with intra-operative injuries include:
- Increased length of stay. This is due to ophthalmology consults required, associated infections and treatment.
- Increased costs. This is due to increased length of stay, cost of treating the complications.
- Pain and discomfort for the patient. Corneal abrasions are extremely painful for the patient and the treatment consists of drops and ointments applied in the eye which may cause further discomfort for the patient.
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

The most commonly employed method is to use tape or a general purpose adhesive dressing. Unfortunately the adhesive used on the tape or dressing will generally be inappropriate for this use. The adhesive strength may change when reaching body temperature, or over time.
As the operation progresses this can cause the adhesive to stop working and become gooey, allowing the eyelids to move apart, and leaving behind a sticky residue. This leaves the cornea exposed to epithelial drying and/or abrasions, sometimes caused by the tape that was originally applied to protect the cornea. Alternatively, the adhesive strength may increase, which upon removal can result in eyelid bruising, tears, or eyelash removal.
Rolls of tapes are often “laying around” the operating theatre or kept in health care workers' pockets.
Therefore, they can be a source of hospital-acquired infections (HAI's) such as Methicillin-resistant Staphylococcus aureus (MRSA) & Vancomycin-resistant Enterococcus (VRE), with a 2010 study showing that 50% of partially used tape rolls tested positive for MRSA, VRE or both.
Most tapes and dressings are non-transparent and so it is not possible to see if the patient’s eyes are opened or closed throughout the case. It is not uncommon for the eyelids to move open as the case progresses, even with adhesive tapes stuck onto them. In a practical sense, these medical tapes/dressings may be difficult to remove from a patient because their ends can become stuck flush with the skin. The possibility of tape removal causing trauma is also significantly increased in older people, people with sensitive skin, dermatitis, dehydration or side effects of medications.
As noted above, there have been several studies looking at the efficacy and safety of eye ointments/lubricants as adjuncts with tape or as a stand-alone management for intra-operative eye closure. Unfortunately many in common use have problems. Petroleum gel is flammable and is best avoided when electrocautery and open oxygen are to be used around the face. Preservative-free eye ointment is preferred, as preservative can cause corneal epithelial sloughing and conjunctival hyperemia.
They have been implicated in blurred vision in up to 75% of patients and they do not protect from direct trauma.
Specially made eyelid occlusion dressings are available commercially, such as EyeGard (manufactured in the USA by KMI Surgical and marketed by Sharn Anesthesia), EyePro (Andsco Medical Pty Ltd, Australia) and Anesthesia-Aid (Sperian Protection). These dressings overcome most of the problems associated with tape or general purpose dressings.
Topical and intralesional (injected into the affected areas) corticosteroid drugs may be used, such as fluocinonide, clobetasol propionate or triamcinolone acetonide. Oral candidiasis may develop with long term topical steroid use, and sometimes antimycotics such as miconazole gel or chlorhexidine mouthwash are used to prevent this. Topical ciclosporin is sometimes used.
Dapsone is sometimes used as a steroid sparing agent. The dose is often increased very slowly in order to minimize side effects. Systemic steroids, such as prednisone or prednisolone may be needed in severe cases. Many other drugs have been used to treat mucous membrane pemphoid, including azathioprine, cyclophosphamide, methotrexate, thalidomide, mycophenolate mofetil, leflunomide, sulphasalazine, sulphapuridine, sulphamethoxypiridazine, tetracyclines (e.g. minocycline, doxycycline) and nicotinamide.
Simple measures that can be taken include avoidance of hard, sharp or rough foods, and taking care when eating. Good oral hygiene is also usually advised, and professional oral hygiene measures such as periodontal scaling.
Currently treatment of ARN consists of antiviral therapy administered orally. Typical antiviral agents used include famciclovir, valganciclovir, and valacyclovir. While on these medications, a patient's kidney function should be watched. Some physician's also may administer the antiviral agents via intravitreal delivery. Though controversial, some physicians administer steroids (prednisone) and antithrombotic therapy (aspirin).
Some commonly admistered antiviral agents are as follows:
- Acyclovir
- Famciclovir
- Valacyclovir
- Gancicilovir
- Valganciclovir
Lid lag is the static situation in which the upper eyelid is higher than normal with the globe in downgaze. It is most often a sign of thyroid eye disease, but may also occur with cicatricial changes to the eyelid or congenital ptosis. Lid lag differs from Von Graefe's sign in that the latter is a dynamic process.It can also be the manifestaition of chemosis (swelling (or edema) of the conjunctiva)
Treatments for CCCA remain investigational. Altering hair care practices has not been proven to assist in hair rejuvenation. High-dose topical steroids, antibiotics, immunomodulators such as tacrolimus (Protopic) and pimecrolimus (Elidel), and anti-androgen/5alpha Reductase inhibitors have been used with unknown efficacy.
While there is no prevention for ARN, exposing a patient to antiviral agents in the earlier phases of the outbreak tend to decrease the duration of the active phase of the disease. Taking antiviral agents after the issue is resolved seems to lessen the chance of it spreading to the other eye.
Von Graefe's sign is the lagging of the upper eyelid on downward rotation of the eye, indicating exophthalmic goiter (Graves' Disease). It is a dynamic sign, whereas lid lag is a static sign which may also be present in cicatricial eyelid retraction or congenital ptosis.
A pseudo Graefe's sign (pseudo lid lag) shows a similar lag, but is due to aberrant regeneration of fibres of the oculomotor nerve (III) into the elevator of the upper lid. It occurs in paramyotonia congenita.
A pseudo Graefe's sign is most commonly manifested in just one eye but can occasionally be observed in both. The reason only one eye is affected is not yet clear.
Even though some patients undergo spontaneous remission of symptoms within a year, many need treatment. The first step is the regulation of thyroid hormone levels by a physician.
There is some published evidence that a total or sub-total thyroidectomy may assist in reducing levels of TSH receptor antibodies (TRAbs) and as a consequence reduce the eye symptoms, perhaps after a 12-month lag. However, a 2015 meta review found no such benefits, and there is some evidence that suggests that surgery is no better than medication; and there are risks associated with a Thyroidectomy, as there are with long-term use of anti-thyroid medication.
Topical lubrication of the ocular surface is used to avoid corneal damage caused by exposure. Tarsorrhaphy is an alternative option when the complications of ocular exposure can't be avoided solely with the drops.
Corticosteroids are efficient in reducing orbital inflammation, but the benefits cease after discontinuation. Corticosteroids treatment is also limited because of their many side effects. Radiotherapy is an alternative option to reduce acute orbital inflammation. However, there is still controversy surrounding its efficacy. A simple way of reducing inflammation is to stop smoking, as pro-inflammatory substances are found in cigarettes.
Surgery may be done to decompress the orbit, to improve the proptosis, and to address the strabismus causing diplopia. Surgery is performed once the patient's disease has been stable for at least six months. In severe cases, however, the surgery becomes urgent to prevent blindness from optic nerve compression. Because the eye socket is bone, there is nowhere for eye muscle swelling to be accommodated, and, as a result, the eye is pushed forward into a protruded position. In some patients, this is very pronounced. Orbital decompression involves removing some bone from the eye socket to open up one or more sinuses and so make space for the swollen tissue and allowing the eye to move back into normal position and also relieving compression of the optic nerve that can threaten sight.
Eyelid surgery is the most common surgery performed on Graves ophthalmopathy patients. Lid-lengthening surgeries can be done on upper and lower eyelid to correct the patient's appearance and the ocular surface exposure symptoms. Marginal myotomy of levator palpebrae muscle can reduce the palpebral fissure height by 2–3 mm. When there is a more severe upper lid retraction or exposure keratitis, marginal myotomy of levator palpebrae associated with lateral tarsal canthoplasty is recommended. This procedure can lower the upper eyelid by as much as 8 mm. Other approaches include müllerectomy (resection of the Müller muscle), eyelid spacer grafts, and recession of the lower eyelid retractors. Blepharoplasty can also be done to debulk the excess fat in the lower eyelid.
An article in the New England Journal of Medicine reports that treatment with selenium is effective in mild cases.
A large European study performed by the European Group On Graves' Orbitopathy (EUGOGO) has recently shown that the trace element selenium had a significant effect in patients with mild, active thyroid eye disease. Six months of selenium supplements had a beneficial effect on thyroid eye disease and were associated with improvement in the quality of life of participants. These positive effects persisted at 12 months. There were no side effects.
A summary of treatment recommendations was published in 2015 by an Italian taskforce, which largely supports the other studies.
Initial treatment involves addressing any existing infections that may have occurred due to the broken state of the skin. Existing wounds are treated with warm compresses, non-adherent (non-stick) dressing, and topical antibiotic ointment. Immunosuppressive agents are administered in attempt to decrease blistering; this is not often effective. The first medication given aiming to heal the wounds are high dose corticosteroids. This is followed by steroid sparing agents which may reduce steroid intake and therefore lessen the side effects. Skin lesions are more likely to respond to this line of treatment than mucosal lesions. However, a high level of caution is advised in patients with a confirmed malignancy, where immunosuppression is vital and dictates treatment options. If the initial therapy fails to control the symptoms of PNP, and the condition of the patient deteriorates, a more aggressive approach may be necessary.
Prednisone is an immunosuppressive agent which affects all of the organ systems. Effects on the cellular level include cell activation, replication, differentiation, and mobility. The overall goal is to decrease blistering (inhibition of immediate and delayed hypersensitivity) through decreasing the production of autoantibodies. In order to suppress the production of antibodies, higher doses must be administered. Lesser doses can be prescribed in order to achieve suppression of monocyte function.
The following methods are employed in the treatment of basal-cell carcinoma (BCC):
Photodynamic therapy (PDT) is a new modality for treatment of basal-cell carcinoma, which is administrated by application of photosensitizers to the target area. When these molecules are activated by light, they become toxic, therefore destroy the target cells. Methyl aminolevulinate is approved by EU as a photosensitizer since 2001. This therapy is also used in other skin cancer types. The 2008 study reported that PDT was a good treatment option for primary superficial BCCs, reasonable for primary low-risk nodular BCCs, but a 'relatively poor' option for high-risk lesions.
Surgery: For individuals with trichiasis, a bilamellar tarsal rotation procedure is warranted to direct the lashes away from the globe. Evidence suggests that usage of a lid clamp and absorbable sutures would result in reduced lid contour abnormalities and granuloma formulation post-surgery. Early intervention is beneficial as the rate of recurrence is higher in more advanced disease.
If not treated properly with oral antibiotics, the symptoms may escalate and cause blindness, which is the result of ulceration and consequent scarring of the cornea. Surgery may also be necessary to fix eyelid deformities.
Without intervention, trachoma keeps families shackled within a cycle of poverty, as the disease and its long-term effects are passed from one generation to the next.
As mentioned above, primary cicatricial alopecias are classified by the predominant type of inflammatory cells that attack the hair follicles: i.e., lymphocytes, neutrophils, or mixed inflammatory cells. Treatment strategies are different for each subtype and detailed treatment options are beyond the scope of this discussion. However, certain general principals are reviewed below.
Treatment of the lymphocytic group of cicatricial alopecias (including lichen planopilaris, frontal fibrosing alopecia, central centrifugal alopecia, and pseudopelade (Brocq) involves use of anti-inflammatory medications. The goal of treatment is to decrease or eliminate the lymphocytic inflammatory cells that are attacking and destroying the hair follicle. Oral medications may include hydroxychloroquine, doxycycline, mycophenolate mofetil, cyclosporine, or corticosteroids. Topical medications may include corticosteroids, tacrolimus, pimecrolimus, or Derma-Smoothe/FS scalp oil. Triamcinolone acetonide, a corticosteroid, may be injected into inflamed, symptomatic areas of the scalp.
Treatment of the neutrophilic group of cicatricial alopecias (folliculitis decalvans, tufted folliculitis) is directed at eliminating the predominant pathogenic microbes that are invariably involved in the inflammatory process. Oral antibiotics are the mainstay of therapy, and topical antibiotics may be used to supplement the oral antibiotics. In dissecting cellulitis, pathogenic microbes are not usually present. Isotretinoin in small doses may be helpful in treating dissecting cellulitis.
Treatment of the mixed group of cicatricial alopecias (folliculitis keloidalis) may include antimicrobials, isotretinoin, and anti-inflammatory medications.
You should discuss any treatment with your dermatologist, who will also explain potential side effects, as well as laboratory tests that are needed before starting treatment and sometimes are monitored during treatment.
The course of cicatricial alopecia is usually prolonged. Treatment is continued until the symptoms and signs of scalp inflammation are controlled, and progression of the condition has been slowed. In other words, itching, pain, tenderness, and burning have cleared, scalp redness, scaling, and/or pustules are no longer present, and the progression of the hair loss has been stopped or slowed. Treatment may then be stopped. Unfortunately, the cicatricial alopecias may reactivate after a quiet period and treatment may have to be repeated.
Surgical treatment for cosmetic benefit is an option in some cases after the disease has been inactive for one to two or more years. Hair restoration surgery or scalp reduction may be considered in these instances.
Risk factors of progressive and severe thyroid-associated orbitopathy are:
- Age greater than 50 years
- Rapid onset of symptoms under 3 months
- Cigarette smoking
- Diabetes
- Severe or uncontrolled hyperthyroidism
- Presence of pretibial myxedema
- High cholesterol levels (hyperlipidemia)
- Peripheral vascular disease
