GLANDS OF EYELIDS 1. Meibomian glands. In tarsal plate arranged vertically. These are modified sebaceous glands. Their ducts open at the lid margin. Their secretion constitutes the oily layer of tear film. 2. Glands of Zeis. These are also sebaceous glands which open into the follicles of eyelashes.
Slide 7-

3. Glands of Moll. These are modified sweat glands situated near the hair follicle. They open into the hair follicles or into the ducts of Zeis glands. 4. Accessory lacrimal glands of Wolfring. These are present near the upper border of the tarsal plate.

Edema of lids Inflammatory edema Dermatitis, stye, insect bite, blepharitis Passive edema Renal disease, Cardiac failure, Cavernous sinus thrombosis

INFLAMMATIONS OF THE EYELIDS Blepharitis 1. Anterior blepharits. 2. Posterior blepharitis.
Slide 10-

INFLAMMATIONS OF THE EYELIDS Blepharitis
Slide 11-

INFLAMMATIONS OF THE EYELIDS Anterior blepharits Squamous Ulcerative Treatment Hot compress Lid hygiene, cleaning with diluted baby shampoo Topical : antibiotic, steroids, tear substitute Oral : Azithromycin 500 mg OD for 3 days.
Slide 12-

INFLAMMATIONS OF THE EYELIDS Posterior blepharitis Meibomian seborrhoea Meibomianitis Treatment: Warm compress, lid hygiene & massage. Oral doxycyclin or minocyclin for 6 wks.
Slide 13-

INFLAMMATION OF GLANDS OF LIDS Hordeolum externum or stye Suppurative inflammation of gland of Zeis. Hordeolum internum Suppurative inflammation of meibomian gland Chalazion Chronic inflammatory granuloma of meibomian gland.
Slide 14-

STYE (EXTERNAL HORDEOLUM)
Slide 15-

It is an acute suppurative inflammation of gland of the Zeis. Causative organism commonly involved is Staphylococcus aureus. Predisposing factors. Refractive error Blepharitis Habitual rubbing of eyelids Diabetes Mellitus STYE (EXTERNAL HORDEOLUM)
Slide 16-

Symptoms and signs Pain Redness Swelling Watering Other predisposing factors
Slide 17-

Treatment Hot fomentation Antibiotic eye ointment Anagesics Oral antibiotics Treatment of underlying cause
Slide 18-

CHLAZION
Slide 19-

It is also called a tarsal or meibomian cyst. It is a chronic non-infective granulomatous inflammation of the meibomian gland. Predisposing factors. Refractive error Blepharitis Habitual rubbing of eyelids Diabetes Mellitus CHLAZION
Slide 20-

Clinical course and complications Complete spontaneous resolution may occur rarely. Occasionally, it may burst on the conjunctival side, forming a fungating mass of granulation tissue. Secondary infection leads to formation of hordeolum internum. Calcification may occur, though very rarely. Malignant change into meibomian gland carcinoma may be seen occasionally in elderly patients.
Slide 21-

Treatment 1. Conservative treatment. 2. Intralesional injection of long-acting steroid. 3. Incision and curettage. 4. Diathermy.

INTERNAL HORDEOLUM It is a suppurative inflammation of the meibomian gland associated with blockage of the duct. It may occur as primary staphylococcal infection of the meibomian gland or due to secondary infection in a chalazion (infected chalazion). Treatment. It is similar to hordeolum externum, except that, when the pus is formed, it should be drained by a vertical incision from the tarsal conjunctiva.
Slide 24-

ANOMALIES IN POSITION OF THE LASHES AND THE LIDS Blepharospasm Trichiasis Entropion Ectropion Symblepharon Ankyloblepharon Blepharophimosis Lagophthalmos Ptosis.
Slide 25-

Blepharospasm Involuntary, sustained and forcible closure of lids. Essential blepharospasm Reflex blepharospasm Treatment: Botulinum toxin Facial denervation
Slide 26-

Trichiasis Misdirection of cilia, directed backwards to rub cornea. Trachoma, blepharitis, scars, chemical burns, Steven-Johnson synd, Treatment: Epilation, Electrolysis, Cryosurgery, Argon laser application.
