Slide 16-

Roles and Characteristics of the eyelids Eye protection Regular blink: protection and stability of the tear film Rich of glands Adequate blood supply
Slide 17-

The Anatomy Corneal epithelium Conjunctival epithelium Tear film Clinical ocular surface consist of conjunctiva cornea eyelids lacrimal gland lacrimal passages
Slide 18-

Tear Secretion Lacrimal gland Producing the watery part of the tear film called the aqueous. Meibomian glands Producing lipids which keep the tear film from evaporating. Goblet cells of the conjunctiva Producing mucin which allows the wetting of the ocular surface as well as stabilizes the tear film. www.virtualmedicalcentre.com
Slide 19-

Tear Film in relation to Cornea
Slide 20-

Tear and the Tear Film Function : 1.Cleaning 2.Wetting ocular surface 3.Bacteriostasis 4.Supporting the cornea (oxygen supply) http://www.drmalcolmmckellar.co.nz
Slide 21-

Concept The ocular surface is a complex biological continuum responsible for the maintenance of corneal clarity, elaboration of a stable tear film for clear vision, as well as protection of the eye against microbial and mechanical insults. Comprising a variety of disorders on cornea, eyelid, conjunctiva, lacrimal apparatus and tear film.

Slide 25-

Conception Dry eye - is a chronic lack of sufficient lubrication and moisture in the eye. Its consequences range from subtle but constant irritation to ocular inflammation of the anterior (front) tissues of the eye.
Slide 26-

Clinical Manifestation Dry eye symptoms asthenopia irritation, grittiness dryness burning light sensitivity pink-eye Do you regularly experience one or several symptoms above? Some diseases and conditions (like Rheumatoid arthritis, Lupus and Sjögren’s Syndrome) also cause chronic Dry Eye in many patients. Activities like Reading, Wearing contact lenses or Working on the Computer may cause Dry Eye.
Slide 27-

Diagnostic Tests for Dry Eye Dry Eye questionnaire Lacrimal river width Schirmer test – uses paper strips under eyelid to measure the wetness that collects over a specific period of time. Break-up time of tear film (BUT) Staining – uses special dyes to highlight areas of possible damage to the eye surface. Tear lab – measuring tear osmolarity Tear ferning test Lactoferrin contents Tear penetration pressure test Corneal tonographic map Impression cytology
Slide 28-

Diagnosing Schirmer test, BUT, Staining Foundation Symptom Instability of tear film Damage to epithelium Tear penetration pressure increasing

Meibomian Gland Dysfunction http://www.dryeyezone.com
Slide 35-

http://www.revophth.com Etiological Factor Failure of the glands to produce or secrete lipids. Wax ester declining and cholesterol increasing make the symptoms worse . Lack of tears and tear penetration pressure increasing. Lupus, brandy nose etc.
Slide 36-

Clinical Manifestation Common in aged people and who lived in cold region. No specific symptoms. Lid-margin mostly thickening; abnormal secretion while pressurizing. Disorder in Meibomian gland, eyelid, conjunctiva. Figure: Notching of the lid caused by loss of meibomian glands. http://www.eyehealthnutrition.com
Slide 37-

Diagnosing Absence of Meibomian gland. The gland orifices are often compromised due to stenosis or closure. A declining quality and quantity of lipid secretion. Any one of the physical signs can make the diagnosis of Meibomian gland dysfunction if the patient has clinical symptoms. Figure: No visible meibomian gland orifices: Eversion of the lower lids in both eyes showed atresic meibomian glands. http://www.ophmanagement.com

Slide 40-

Treatment Clearing Hot fomentation on eyelids for 5~10mins. Massaging the eyelids. Swabbing the lid-margin with mild cleaning solution.
Slide 41-

Treatment Antibiotics oral administration. Local Medication Antibiotic eye drops Glucocorticoid eye drops (short term) Artificial tears
Slide 42-

Classification Corneal, conjunctival lesion Squamous epithelization type Limbal stem cell deficiency type Tear film disorders Aqueous tear deficiency Lipid tear deficiency Mucoprotein deficiency Kinetic disorders of lacrimal fluid
Slide 43-

Treatment Reconstruction Epithelium, limbal stem cells Lacrimal secretion, tear film Innervation (nerve restore) Structure and function of eyelid Surgical operation To re-establish conjunctiva, cornea, tear film and eyelid.

Dry Eye Disease Workshop
Slide 45-

Treatment According to the clinical category For tear deficiency: Maintain moisture in the eyes; reducing the evaporation; increasing the secretion; controlling inflammation & immunoreaction. For excess-evaporation: Therapy of Meibomian gland dysfunction; controlling inflammation; cleaning eyelid; decreasing the evaporation; lipid replacement. According to the eye conditions For intermittent symptoms: Artificial tears add volume to the tear film as long as they remain in contact with the surface of the eye. For midrange dry eye: Artificial tears and punctal occlusion. For Severe dry eye: Appending cyclosporin, surgery.
