====Corneal Sensation====
====Corneal Sensation====
Corneal hyperesthesia or reduced sensation may be present in severe and [[chronic]] dry eye disease. Corneal sensation can be measured using a cotton tip applicator.
On corneal sensation test, chronic keratoconjunctivitis sicca is characterized by corneal hyperesthesia or reduced sensation.
====Tear Break Up Time====  
====Tear Break Up Time====  
A tear breakup time (TBUT) test measures the time it takes for tears to break up in the eye. The proper method of TBUT testing is using a [[fluorescein]] impregnated strip. The dye is distributed by blinking, and the patient is then asked to stare straight ahead without blinking. The tear film is observed under the light of a [[slit lamp]].
On tear breakup time (TBUT), keratoconjunctivitis sicca is characterized by tear film instability and rapid evaporation. The tear film is observed under the light of a [[slit lamp]].
====Ocular Surface Staining====
====Ocular Surface Staining====
Interpretation of staining is based on intensity and location using a grading scale described by Van Bijsterveld. The nasal and temporal [[conjunctiva]] and the [[cornea]] are graded on a scale of 0-3 with a maximum possible score of 9.
On ocular surface staining, keratoconjunctivitis sicca in a patients with [[aqueous tear]] deficiency may be characterized by [[fluorescein]], [[Rose Bengal]], or lissamine green staining on the interpalpebral conjunctiva.
In aqueous tear deficiency, the interpalpebral conjunctiva is the most common location for rose Bengal staining. The severity of staining has been shown to correlate with the degree of aqueous deficiency, tear film instability, and reduced [[mucin]] production by conjunctival [[goblet cell]] and [[epithelial cells]]
====Schirmer's Test====
====Schirmer's Test====
A [[Schirmer's test]] can measure the amount of moisture bathing the eye. A five-minute Schirmer's test with and without [[anesthesia]] is performed, and wetting under 5 mm is considered diagnostic for dry eyes. It is most useful in the diagnosis of patients with severe aqueous deficiency, but is relatively insensitive for patients with mild dry eye.
On [[Schirmer's test]], keratoconjunctivitis sicca caused by severe aqueous deficiency is characterized by wetting under 5 mm.
====Tear Protein Analysis====
 
A tear protein analysis test measures the [[lysozyme]] contained within tears, and may be useful for selection of treatment or following up the patient for response to treatment.<ref name="pmid26605353">{{cite journal| author=D'Souza S, Tong L| title=Practical issues concerning tear protein assays in dry eye. | journal=Eye Vis (Lond) | year= 2014 | volume= 1 | issue=  | pages= 6 | pmid=26605353 | doi=10.1186/s40662-014-0006-y | pmc=4604107 | url=http://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=26605353  }} </ref>
====Matrix Metalloproteinase 9 (InflammaDry)====

Rapid in-office test, InflammaDry (matrix metalloproteinase 9), has been shown to be elevated in the tears of patients with dry eye disease.
 
====Tear film interferometry====
Tear film interferometry is a noninvasive method of grading tear film quality and estimating the thickness of the lipid layer.
 
On Tear film interferometry, keratoconjunctivitis sicca caused by [[mebomian gland]] dysfunction characterized by abnormal colored tear film.
