Eyelid disorders include conditions such as inflammation, styes, chalazia, drooping eyelids, inward or outward turning of the eyelids and eyelid masses. Treatment is planned according to the cause of the condition, its effect on the ocular surface and the examination findings.
Eyelid disorders consist of various health conditions that affect the structure and movement of the eyelids and their ability to protect the ocular surface. Infections, inflammation, blocked glands, structural abnormalities and eyelid masses are included in this group. The eyelids help keep the ocular surface moist and protect it from external factors. Eyelid problems can therefore affect not only appearance but also visual comfort and eye health. Irritation, watering, redness, swelling and changes in eyelid shape are common symptoms. Treatment is determined according to the cause of the condition and its effect on the ocular surface.
Structure and Function of the Eyelid
The eyelid is a multilayered structure consisting of skin, muscles, supporting tissues and the conjunctiva covering its inner surface. The front section contains the skin and the muscle that closes the eye. The back section contains the tarsus, which gives the eyelid its shape, and the conjunctiva, which comes into contact with the ocular surface. The oil glands within the eyelid help maintain the balance of the tear film. Opening the upper eyelid depends on the coordinated function of the muscles that lift it. A disorder affecting any of these tissues may alter the eyelid's position or its ability to protect the ocular surface.
The main structural components of the eyelid include:
- Eyelid skin.
- Muscles around the eye that close the eyelids.
- Supporting tissue called the tarsus.
- Conjunctival layer.
- Muscles that lift the eyelid.
- Oil glands and supporting fatty tissues.
What Is Blepharitis?
Blepharitis is inflammation that develops along the eyelid margins and at the base of the eyelashes. Bacterial accumulation, oil gland dysfunction, seborrhoeic dermatitis and certain skin conditions may contribute to this condition. Patients may experience crusting at the base of the eyelashes, burning, itching and redness. Discharge and the eyelids sticking together may occur, particularly in the morning. Blepharitis may persist for a long time in some people and flare up again during certain periods. It may also affect the tear film and cause dry eyes and irritation.
Regular eyelid hygiene forms the basis of treatment. In suitable patients, warm compresses may help remove deposits from the eyelid margins. Artificial tear drops may be used if the ocular surface is dry. If a bacterial infection or significant inflammation is detected, appropriate eye drops and ointments may be added to the treatment. Oral medication may also be considered in some persistent cases. The treatment approach is determined according to the cause of the blepharitis and the patient's ocular surface findings.
Difference Between a Stye and a Chalazion
Styes and chalazia are two conditions that cause eyelid swelling but develop through different mechanisms. A stye usually develops due to an infection of the eyelid glands or eyelash follicles. The swelling is generally painful and may be accompanied by redness and tenderness. A chalazion is a swelling caused by a blockage of the oil glands within the eyelid and may persist for longer. It is generally painless, although tenderness may occur during the early stages. Large chalazia may press on the ocular surface and cause temporary blurred vision.
Warm compresses and eyelid care may be used during treatment. Appropriate medication may be planned if signs of infection are present. Squeezing the swelling or attempting to treat it at home may cause the infection to spread and damage the surrounding tissues. Medication injections or surgical drainage may be considered for chalazia that do not resolve for a long time. Other conditions may need to be ruled out when masses recur in the same area or do not respond to conventional treatments. Recurrent eyelid swelling, particularly in older patients, may be assessed through pathological examination when considered necessary.
What Is a Drooping Eyelid?
A drooping eyelid is a condition in which the upper eyelid is positioned lower than normal. Medically known as ptosis, it may occur in one or both eyes. Mild eyelid drooping may primarily cause a change in appearance. In more pronounced cases, it may cover the pupil and restrict the upper visual field. Patients may raise their eyebrows or tilt their heads backwards to see more comfortably. Over time, this may cause tension in the forehead, headaches and neck discomfort.
Ptosis may be present from birth or develop later in life. In age-related cases, the connective tissue of the muscle that lifts the eyelid may become loose or separated. Contact lens use, previous surgery, trauma and certain muscle or nerve diseases may also cause eyelid drooping. During the examination, the position of the eyelid relative to the pupil and the strength of the muscle that lifts the eyelid are measured. Pronounced eyelid drooping in children must also be assessed because it may affect visual development. Eyelid drooping that develops suddenly and is accompanied by double vision, differences in pupil size or other neurological symptoms should be investigated without delay.
Symptoms that may occur with eyelid drooping include:
- Restriction of the upper visual field.
- Constant need to raise the eyebrows.
- Tilting the head backwards.
- Tension in the forehead.
- Headache or neck pain.
- A difference in eyelid height between the eyes.
How Is Eyelid Drooping Treated?
Treatment for eyelid drooping is planned according to how low the eyelid sits and the function of the muscle that lifts it. If the muscle has sufficient strength, repairing the connective tissue or repositioning the muscle may be preferred. During this procedure, the eyelid height and its relationship with the ocular surface are assessed. Surgical methods performed through the inner surface of the eyelid may be suitable in some mild cases. A different approach may be required in patients with significant weakness of the lifting muscle. Particularly in some congenital cases, the eyelid may be supported by the forehead muscle using a suspension technique.
Whether surgery is performed under local or general anaesthesia is determined according to the patient's age and medical condition. Local anaesthesia may be preferred for adult patients under suitable conditions. General anaesthesia may be required for children or when the procedure is more extensive. Surgical planning considers not only opening the eyelid but also ensuring that the eye can close comfortably. Excessive correction may leave the ocular surface exposed and cause dryness. The method is therefore selected by evaluating eyelid movements and the condition of the ocular surface together.
What Is Ectropion?
Ectropion is the outward turning of the eyelid away from the ocular surface. It most commonly affects the lower eyelid and may be associated with age-related tissue laxity. When the eyelid turns outward, the conjunctiva on its inner surface is exposed to more air. This may cause redness, dryness, irritation and discomfort in the eye. The small opening that drains tears towards the nose may also turn outward with the eyelid. As a result, tears cannot drain normally and may run down the cheek.
Ectropion does not develop only because of age-related laxity. Facial paralysis, previous surgery, trauma, burns and scar tissue around the eyelid may also cause the eyelid to turn outward. Artificial tear drops or ointments that protect the ocular surface may be used to provide temporary relief. Persistent structural abnormalities may require tightening of the eyelid's supporting tissues. In cases caused by scar tissue, releasing the area that pulls the eyelid outward or using a skin graft may be considered. Treatment is selected according to the cause of the ectropion and the degree to which the ocular surface is affected.
Conditions that may cause ectropion include:
- Age-related eyelid laxity.
- Facial paralysis.
- Previous eyelid surgery.
- Trauma and burns.
- Scar tissue around the eyelid.
- Certain structural eyelid abnormalities.
What Is Entropion?
Entropion occurs when the eyelid margin turns inward and the eyelashes come into contact with the ocular surface. It most commonly affects the lower eyelid and may develop due to the loosening of the supporting eyelid tissues with age. When the eyelashes rub against the cornea, irritation, watering, redness and sensitivity to light may occur. If the friction continues, scratches or more serious tissue damage may develop on the corneal surface. In some patients, the eyelid turns inward only when the eyes are squeezed shut, while in others the condition may become constant. Evaluation should not be delayed if pain or blurred vision develops.
Non-surgical supportive treatments may include artificial tears and eyelid taping in suitable patients. Temporary everting sutures or protective contact lenses may be considered in some cases. However, surgical correction may be required if the structural eyelid abnormality persists. During surgery, loosened eyelid tissues may be tightened and the muscles controlling lower eyelid movement may be repositioned. Different surgical methods may be required in cases caused by scar tissue. The approach used is determined according to the cause of the inward turning and its effect on the cornea.
Symptoms that may occur with entropion include:
- Irritation and a foreign body sensation in the eye.
- Constant watering.
- Sensitivity to light.
- Redness of the ocular surface.
- Discomfort while blinking.
- Blurred vision.
Eyelid Masses
Eyelid tumours include different tissue changes that may be benign or malignant. It is important to assess lesions on the eyelid that are new, growing or do not resolve for a long time. Not every eyelid swelling is malignant, and some masses may result from more common causes such as cysts, styes or chalazia. However, areas that bleed spontaneously, develop crusting or do not heal may require more detailed examination. Loss of eyelashes in a specific area and changes in the shape of the eyelid margin are also findings that require attention. A definitive assessment is made by examining the lesion and, when necessary, evaluating a tissue sample.
Basal cell carcinoma is one of the malignant lesions that may occur on the eyelid. This tumour usually grows slowly but may extend into the surrounding tissues. Squamous cell carcinoma may develop more rapidly in some cases and may require assessment of the surrounding tissues and lymph nodes. Sebaceous carcinoma may originate from the oil glands in the eyelid and can sometimes be mistaken for a recurrent chalazion. Persistent or frequently recurring swelling in the same area should therefore not be regarded simply as an eyelid infection. The examinations required are determined according to the appearance and location of the mass and the patient's medical history.
Signs that may require a more detailed assessment include:
- A rapidly growing eyelid mass.
- A wound or crusted area that does not heal.
- Spontaneous bleeding.
- Loss of eyelashes in a specific area.
- Changes in the shape of the eyelid margin.
- Recurrent swelling in the same area.
How Are Eyelid Tumours Treated?
Treatment of an eyelid mass is planned according to the type and location of the lesion. Suspicious lesions may first require a biopsy or pathological examination after surgical removal. If the lesion is found to be malignant, the aim is to remove the tumour tissue with appropriate surgical margins. In some patients, pathological assessment of the surgical margins during the operation may be preferred. However, the same method is not used in every case, and planning varies according to the characteristics of the tumour. Maintaining the eyelid's ability to close and protect the ocular surface is also important after surgery.
The method used to close the tissue defect after removing the tumour is determined according to the size of the tissue loss. In small areas, the eyelid tissues may be joined directly. For larger tissue defects, surrounding skin and eyelid tissue may be used. Skin grafts, mucosal grafts or different supporting tissues may be used when necessary. The purpose of reconstruction is to restore eyelid function and prevent the ocular surface from remaining exposed. The duration of follow-up after treatment varies according to the pathology results and the characteristics of the tumour.
Methods that may be used for eyelid reconstruction include:
- Repositioning surrounding tissues.
- Reconstruction using eyelid tissue.
- Skin grafting.
- Use of a mucosal graft.
- Reconstruction of supporting tissues.
Dermatochalasis and Eyelid Sagging
Dermatochalasis is the loosening and gradual accumulation of excess eyelid skin. It generally affects the upper eyelid, although loose skin and bags may also develop on the lower eyelid. When excess skin on the upper eyelid becomes pronounced, it may descend over the eyelashes. In some people, this may restrict the visual field and cause a feeling of heaviness around the eyes. Dermatochalasis is not the same as ptosis, in which the eyelid itself sits lower than normal. However, both conditions may occur together in some patients.
During the examination, the amount of excess skin, eyelid height and eyebrow position are evaluated together. When considered necessary, excess skin and appropriate tissues may be adjusted through a surgical procedure called blepharoplasty. If lower eyelid bags are present, removal or repositioning of fatty tissue is planned according to the patient's anatomy. Removing the same amount of tissue or using the same surgical technique is not appropriate for every patient. Preserving the eyelid's ability to close is an important part of surgical planning. The scope of the procedure is determined by considering the effect on the visual field and the structural characteristics of the eyelid.
The main conditions assessed in dermatochalasis include:
- Excess skin on the upper eyelid.
- Eyelid skin descending over the eyelashes.
- Restriction of the visual field.
- Bags under the lower eyelid.
- Tissue laxity around the eyelid.
- Accompanying eyebrow drooping or ptosis.
After Eyelid Surgery
Swelling, bruising and mild tenderness may occur after eyelid surgery. The duration of these symptoms varies depending on the extent of the procedure and the individual's healing characteristics. Applying a cold compress as recommended during the first few days may help control swelling. Keeping the head slightly elevated while sleeping may also provide relief for some patients. Recommended eye drops or ointments should be used regularly for the specified period. It is important not to rub the surgical area and to protect it from direct pressure.
Blood-thinning medications, aspirin and other regularly used treatments should not be discontinued based on the patient's own decision. Adjustments involving these medications before and after surgery should be planned together with the physician monitoring the treatment. The timing of suture removal and the intervals between follow-up appointments may vary according to the surgical method used. Recommendations regarding sun protection and returning to daily activities should be followed. If severe pain, sudden loss of vision, rapidly increasing swelling or significant bleeding develops, an assessment should be performed without delay.
