CHAPTER 15 Lids What are the layers of eyelids? •• •• •• •• •• •• •• Fig 15.1: From the front to back Cutaneous layer (skin) Areolar layer (loose areolar tissue) Muscular layer (orbicularis oculi) Sub Muscular areolar tissue Fibrous layer (tarsal plate) Layer of smooth muscle (Muller’s muscle) Conjunctival layer (mucous layer) −− Grey line separates fibrous layer from muscular layer mebooksfree.com Lids 257 Write short notes on blepharitis: Chronic inflammation of lid margin Types •• •• •• •• Squamous Ulcerative Posterior blepharitis or meibomitis Parasitic blepharitis – due to Demodex folliculorum and Phthiriasis palpebrarum Squamous blepharitis Fig 15.2: Squamous blepharitis •• •• •• •• •• Due to seborrheic dermatitis Usually associated with dandruff of scalp White coloured scales accumulate among lashes Eyelashes fall out but are replaced without distortion On removal of scales, the underlying surface is red Ulcerative blepharitis Fig 15.3: Ulcerative blepharitis •• Yellow scales glue the lashes together •• Hyperemia, telangiectasia and scaling •• On removing of the crusts, small ulcers are seen around base of the lashes These ulcers bleed Lashes fall and replaced by misdirected ones mebooksfree.com 258 Exam Preparatory Manual for Undergraduates Ophthalmology •• Caused by staphylococcal aureus and epidermidis •• Secondary changes caused by hypersensitivity to staphylococcus exotoxins are: −− Mild papillary conjunctivitis −− Marginal keratitis Symptoms •• •• •• •• •• •• Itching Redness Soreness Lacrimation Mild photophobia Lid crusting Sequela •• •• •• •• •• •• Trichiasis Tylosis (thickening of lid margin) Madarosis ( loss of eye lashes) Poliosis (whitening of eye lashes) Ectropion Stye −− Usually secondary to poor ocular hygiene, frequent rubbing of eyes, exposure to smoke and pollutants and asthenopia Differences between squamous and ulcerative blepharitis Features Squamous Ulcerative Etiology Seborrhea Staphylococcus Deposits on eyelashes Shiny waxy Brittle scales/ulcers Removal of deposits leaves Hyperaemic zone Bleeding ulcers Hair follicles Not destroyed Destroyed Meibomian secretion Vicarious Normal Eyelashes Normal Trichiasis, Madarosis and Poliosis Lid margin may present Chalazion Stye Conjunctiva Mild conjunctivitis Severe conjunctivitis Dryness Absent Present Corneal complications •• Punctate epithelial erosions •• Marginal ulcers May be seen Absent Commonly seen Present Treatment Local •• Removal of scales, crusts and diseased lashes •• Cleaning lid margin with 3% NaHCO₃, betadine, or baby shampoo and artificial tears mebooksfree.com Lids 259 Specific: Antibiotic eye ointment, betadine lotion applied for 2–3 weeks General: Improvement of general health and personal hygiene Dandruff of scalp: Selenium sulphide 2.5% shampoo twice weekly Posterior blebharitis: Systemic tetracycline or doxycycline or erythromycin and antibiotic steroid eye ointment at the lid margin •• Parasitic blepharitis – Removal of nits by forceps and antibiotic ointment to lid margin •• Delousing of patient and family members Write short notes on Hordeolum externum (Stye): Fig 15.4: Zeis gland Fig 15.5: Stye Acute suppurative inflammation of Zeis or Moll’s glands mebooksfree.com 260 Exam Preparatory Manual for Undergraduates Ophthalmology Etiology Due to staphylococcal infection associated with boils, acne, common in children and young adults Also seen in immuno compromised person Symptoms Acute pain along the lid margin Signs Tender, hard swelling seen near lid margin An abscess may form pointing near base of lashes Pain subsides if it gets ruptured There are two stages: •• Stage of cellulitis •• Stage of abscess Treatment Hot fomentation in early stage: •• Systemic – broad spectrum antibiotic •• Analgesics and anti-inflammatory drugs •• Removal of pus by pulling or epilating the involved lash or incision and drainage •• In case of recurrent stye, diabetes and refractive errors have to be ruled out Write short notes on chalazion: Fig 15.6: Tarsal or meibomian cyst Chronic granulomatous inflammation of meibomian gland Etiology Due to chronic irritation caused by an organism of low virulence: •• Small nontender hard swelling in the lid, slightly away from lid margin •• Cosmetic problem •• May cause astigmatism against rule due to pressure on cornea Sequela •• Spontaneous resolution •• Contents may extrude through conjunctiva to resemble fungating mass mebooksfree.com Lids 261 •• •• •• •• Calcification Meibomian cell carcinoma May get secondary infection and form Hordeolum internum Marginal chalazionoccurs in ducts of meibomian gland The granulation tissue projects as a reddish grey nodule on the intermarginal strip Treatment •• Incision and curettage: The lid is everted and vertical incision is made with 11 blade and mucoid material scooped out and the cavity curetted Vertical incision is made to avoid damage to adjacent meibomian glands •• Intralesional injection of Triamcinolone may help in smaller chalazion Write short notes on Hordeolum internum: Acute suppurative inflammation of meibomian gland •• Occurs due to secondary infection of chalazion •• Symptoms are more than in stye because the gland is larger and is embedded deeply in dense fibrous tissue Treatment: Broad spectrum antibiotics and anti-inflammatory drugs to control pain Latter incision and curettage as for chalazion What is Molluscum contagiosum? It is a viral infection of the lids, commonly affecting children It is caused by poxvirus Clinical features: They are multiple, pale, waxy, umblicated swellings around the lid margin Complications: Chronic follicular conjunctivitis and superficial keratitis Treatment: They should be incised and expressed and the interior touched with 5% povidone iodine or pure carbolic acid Write short notes on trichiasis: Fig 15.7: Eyelashes are misdirected backwards and rub against cornea Etiology •• Stage IV Trachoma •• Spastic entropion in elderly person mebooksfree.com 262 Exam Preparatory Manual for Undergraduates Ophthalmology •• Tight bandaging •• Ulcerative blepharitis •• Scars of lid Symptoms •• Foreign body sensation and photophobia •• Redness of conjunctiva and lacrimation Signs •• Misdirected cilia touching the cornea •• Blepharospasm and photophobia if cornea is involved •• Superficial corneal opacities Complications •• Chronic conjunctivitis •• Recurrent corneal abrasions •• Nonhealing corneal ulcer Treatment •• If single or few cilia are involved, epilation or electrolysis at root of hair follicle •• When many cilia are misdirected, surgical correction similar to cicatrical entropion is advised Write short notes on entropion: Fig 15.8: Lid margin rolls inwards Types •• Senile or involutional: Affects only lower lid •• Spastic: Due to spasm of orbicularis oculi of lower lid due to tight bandaging Occurs in lower lid of old people mebooksfree.com Lids 263 •• Cicatrical: Due to contraction of palpebral conjunctiva involves both lids It occurs in trachoma stage IV, ulcerative blepharitis, Burns, Steven Jhonson syndrome, diphtheritic membranous conjunctivitis and pemphigus (pemphigoid) •• Congenital entropion rare: Due to deformity of tarsal plate It involves lower lid only •• Mechanical: Due to lack of support provided by eyeball—seen in phthisis bulbi or enucleated or eviscerated eyes Symptoms and Signs Same as for Trichiasis and those of disturbances of stability of tear film They are foreign body sensation, irritation, abrasion and corneal ulcer Three grades Mild: Posterior border of lid inturned Moderate: Intermarginal strip rotates inwards Severe: Entire lid margin rolls inwards Senile entropion: Seen in old age Usually above 60 years Etiology •• Overriding of preseptal part of orbicularis over pretarsal part with atrophy of subcutaneous tissue with ageing •• Inturning of lower lid tarsus due to weak lower lid retractors and laxity of medial and lateral ligaments •• Loss of posterior support in enophthalmos due to atrophy of orbital fat Treatment Aim of surgery: To restore vertical and horizontal tautness of lid: •• Reattach retractors to tarsal plate •• Shortening of horizontal width of tarsal plate •• Forming a cicatrix between pretarsal and preseptal parts of orbicularis: −− Short term relief: By sticking an adhesive tape to pull lower lid outwards −− Everting sutures: 5–0 vicryl chromic catgut from conjunctiva to skin of lid adjacent to inferior border of tarsus creates cicatrical barrier that maintains eyelid in everted position −− Modified Wheeler operation: Skin incision—parallel to lower lid Orbicularis is dissected and 3mm strip of muscle is double breasted and stitched together with an excision of base down triangle of tarsus Redundant (excess) skin is excised −− Quickert’s procedure: Transverse lid split + everting sutures + horizontal lid shortening −− Modified Jones procedure: Inferior lid retractors are plicated or attached to the tarsus Spastic entropion Due to spasm of Orbicularis oculi: •• Evert the lid by pulling it with adhesive plaster •• Botulinum toxin injected into pretarsal orbicularis to prevent it from overriding mebooksfree.com 264 Exam Preparatory Manual for Undergraduates Ophthalmology Cicatrical Entropion Treatment: Mild to moderate cases with thickened tarsus is treated with wedge resection of tarsus If tarsus is not thickened, Modified Burrow’s operation or Tarsal fracture is done Very extensive scarring may necessitate the replacement of conjunctiva by a mucous membrane graft and a distorted tarsal plate by cartilage graft Congenital Entropion abnormal tarsal plate is resected Abnormal skin fold is excised Write short notes on Ectropion: Fig 15.9: Outward turning of eyelid margin Types •• •• •• •• •• •• Senile or Involutional Spastic Cicatrical Mechanical Paralytic Congenital •• Senile ectropion occurs only in lower lid due to horizontal laxity of eyelid, medial canthal or lateral canthal laxity •• Spastic: Due to blepharospasm when lids are well supported by globe Occurs in children and young adults •• Cicatrical: Due to scarring of skin by chronic conjunctivitis, blepharitis, injuries, burns, ulcers, etc •• Mechanical: Due to dragging of lid tumor with its weight •• Paralytic: Paralysis in orbicularis as in facial palsy - affecting lower lid •• Congenital: Due to deficient eyelid skin - skin grafting to be done Symptoms Epiphora and constant watering of the eyes Signs •• Conjunctiva becomes dry and thickened •• Chronic conjunctivitis due to exposure, exposure keratitis mebooksfree.com Lids 265 Three grades Mild: Only punctum is everted Moderate: Palpebral conjunctiva is visible Severe: Lower fornix is exposed Treatment •• Spastic: Underlying cause of blepharospasm is treated •• Cicatricial: Free lid margin from scar tissue and restore lid to normal position Mild cases Fig 15.10: V-Y operation V shaped incision is made in the skin of lower lid which includes the scar Skin is excised and wound is sutured in Y shaped pattern thus correcting ectropion Extensive scarring: Excision of scar tissue and application of skin graft Split skin graft or full thickness grafts are taken from upper lid, behind the ear, inner side of upper arm or thigh Senile ectropion: Depending on severity the following operations are done −− Mild to moderate cases, a horizontal spindle shaped piece of conjunctiva subconjunctival tissue is removed mm from the punctum and margins are sutured −− For severe cases in mid portion of lower lid, full thickness shortening of lid is done Fig 15.11: Bryon Smith modification of Kuhnt Szymanowski’s procedure Full thickness inverted house (pentagon) shaped excision at least mm away from punctum is done and margins are sutured −− Bryon Smith modification of Kuhnt Szymanowski’s procedure: for severe ectropion which is more marked in the lateral half of lid A base up pentagonal full thickness excision from the lateral third of lid is combined with triangular excision of skin from the area just lateral to lateral canthus to elevate the lid −− Medial ectropion is corrected by modified lazy T operation in which medial vertical pentagon of full thickness lid is excised mm lateral to lower punctum Paralytic ectropion: It occurs due to paralysis of facial nerve, in Bell’s palsy, parotid surgeries, trauma and tumors such as an acoustic neuroma mebooksfree.com Index 411
