Eyelids – Part 3 OPTOM 245 - Fall 2024 Poling Website http://nfurtado.participoll.com Nadine M. Furtado, OD, MSc, FAAO Associate Clinical Professor Head, Ocular Disease & Imaging Service 1 Thank you to Dr. Dalton for providing her past notes to prepare this lecture. Eyelid Positional Issues 6 Case: Eyelid Positional Problems 88yo M c/o constant tearing mainly OS ▪ Occasional FBS OS>>OD ▪ VA OD 20/20 OS 20/25 OU 20/20 Andrew Pearson MD, Eye Surgery in Berkshire. http://www.eyesurgeryinberkshire.co.uk/information_ae/ae_ectropion.html 7 Eyelid Positional Problems Epiphora & FBS Entropion Ectropion Involutional Congenital Cicatricial Spastic Involutional Mechanical Cicatricial Paralytic 8 Entropion Vs. Ectropion Eye Atlas (2014) on Twitter.

Retrieved from https://twitter.com/Eye_Atlas/status/546650973809025025/photo/ 1 ▪ Unilateral or bilateral ▪ More common in the elderly Less common than ectropion ▪ Clinical signs: Rolled-in lid, pseudo-trichiasis, hyperemia, http://optometrist.com.au/entropion/ corneal staining (exposure keratopathy) Secondary: pannus, corneal scarring, infection and ulceration ▪ Sx: FBS, epiphora Pannus 10 Atlas of Ophthalmology @ Online Journal of Ophthalmology https://www.atlasophthalmology. net/photo.jsf;jsessionid=A9F6B6CE63905C45F9BA2C601042A720?node=586&locale=pt Involutional Entropion ▪ Occurs more commonly in the elderly population ▪ Due to degeneration of elastic and fibrous tissues within the eyelid Orbital tissue atrophy allowing the globe to move posteriorly (relative enophthalmos) Increased horizontal lid laxity, decreased vertical lid stability, increased orbital septum laxity Clinical Ophthalmology: A Systematic Approach (7th Edition), Figure 1.68 A 11 Congenital Entropion ▪ A true congenital entropion is rare Primary: abnormal development of tarsus, orbicularis or other musculature Secondary: mechanical (anophthalmos, microphthalmos) EyeEssentials (2011). Before. http://eye-essentials.net/ce1.htm ▪ More common is an epiblepharon - Epiblepharon mild entropion seen in young children A fold of skin that overlaps the eyelid margin, pushing the eyelid margin inward Unlike true congenital entropion this improves with age Consultant 360 (September 2006). Photo clinic: Bilateral Epiblepharon. https://www.consultant360.com/articles/photoclinic-bilateral-epiblepharon 12 Cicatricial entropion ▪ Severe scarring of the palpebral conjunctiva pulls the lid margin towards the globe ▪ Common causes: Cicatrizing conjunctivitis Trachoma Trauma Chemical injuries o Acid or alkali burns Inflammatory conditions Dr. Arteaga, Opthalmic Plastic Surgeon. Entropion. http://www.angelarteaga.es/en/entropion-c-5.php o Stevens-Johnson syndrome, ocular pemphigoid 13 Spastic Entropion Spastic Entropion ▪ Occurs secondarily to neurological, inflammatory or irritative processes of the eyelids Commonly due to surgical trauma or blepharospasm Blepharospasm ▪ Uncontrolled abnormal muscle contraction of the eyelids Usually bilateral; can be primary or secondary Symptoms begin gradually (mild contractions) and can progress to being more frequent and forceful o Secondary causes (range): dry eyes to Tourette's syndrome Myokymia ▪ Abnormal sporadic twitching of the eyelid Typically unilateral; can last a few seconds to several days o Common causes: caffeine, stress, fatigue Note: if other facial muscles may be a neurological condition o E.g., Hemifacial spasm, essential blepharospasm, facial myokymia, facial nerve palsy with synkinesis 14 North American Neuro-Ophthalmology Society (NANOS, 2016). Eyelid Myokymia. Patient Brochure. http://www.nanosweb.org/files/Patient%20Brochures/English/Eyelid%20myokymia.pdf Entropion Tx ▪ Temporary Lubricating drops / ointments, prophylactic antibiotics, lid taping, cyanoacrylate glue, bandage contact lenses, epilation of lashes (minor cases), botulinum toxin ▪ Long Term – treat the underlying cause Electrolysis, mucous membrane graft (cicatricial), eyelid surgery (tighten inferior retractors, horizontally shorten the lid) Clinical Ophthalmology: A Systematic Approach (7th Edition), Figure 1.69 B 15 Ectropion ▪ An outward turning of the eyelid margin Common, especially in the elderly Eye Atlas (2014) on Twitter. Retrieved from https://twitter.com/Eye_Atlas/status/546650973809025025/photo/1 Almost exclusively effects the lower lid ▪ Clinical Signs: Everted lower lid, hyperemia, corneal staining (exposure keratopathy), conjunctival inflammation & thickening Secondary keratinization of tarsal conjunctiva ▪ Sx: FBS, epiphoria Keratinization Clinical Ophthalmology: A Systematic Approach (7th Edition), Figures 1.61 A, B 16 Involutional Ectropion ▪ “Age-related” entropion due to natural aging changes in the lid ▪ Most common form of ectropion ▪ Horizontal lid laxity with medial and lateral canthal tendon laxity Aggravated by gravity Clinical Ophthalmology: A Systematic Approach (7th Edition), Figures 1.62 A and B 17 Mechanical Ectropion ▪ Occurs due to lesions on or near the lid margin that mechanically evert (pull down) the lid Ex: large chalazion, neurofibroma, papilloma Clinical Ophthalmology: A Systematic Approach (7th Edition), Figure 1.67 R. Pace – OPTOM 245 Fall 2012 18 Cicatricial Ectropion ▪ Scarring or contracture of the skin, palpebral conjunctiva or underlying tissues that pulls the eyelid away from the globe Occurs secondary to trauma, burns, radiotherapy, chemical injuries, ichthyosis ▪ Often accentuated by opening the mouth Procianoy F et al Arq.

Ptosis Repair. http://www.chicagoeyelids.com/before- andafter/ptosis-repair/ 27 Congenital Ptosis ▪ Striated muscle dystrophy of the levator muscle Often cause unknown, some are hereditary ▪ Unilateral or bilateral ▪ Clinical signs, in addition to ptotic lid: Absent upper lid crease Poor levator function Woong Chul Choi and Juwan Park.

(2008). https://www.blepharospasm.org/gallery3/index.php/non-surgical- aids/Ptosis_crutch_in_place 38 Pseudoptosis ▪ Variety of causes Lack of support of lids by globe ▪ Artificial eye, microphthalmos, phthisis bulbi, enophthalmos Contralateral lid retraction ▪ Thyroid eye disease Ipsilateral hypotropia ▪ Upper lid follows globe downwards ▪ Disappears when hypotropic eye is fixating Brow ptosis ▪ Excessive skin on the brow, CN7 palsy Dermatochalasis ▪ Excessive skin on upper lids Preseptal or orbital cellulitis ▪ Primarily infectious causes; may be life threatening ▪ Will be discussed with “Orbit” 39
