Purpose: To evaluate contrast sensitivity and disability glare in patients with dry eye using the Contrast Glaretester 1000.
Methods: Contrast sensitivity and disability glare were determined in 33 eyes of 33 patients with dry eye and 30 eyes of 30 healthy control subjects for six target sizes with a visual angle of 6.3–0.7 degrees using the Contrast Glaretester 1000, whose working mechanism is similar to that of the conventional perimetry instrument.
Results: Contrast sensitivity was significantly worse in dry eye group when viewing all target sizes (reduction of 0.10–0.25 log contrast units, p |

Purpose: To evaluate contrast sensitivity and disability glare in patients with dry eye using the Contrast Glaretester 1000.
Methods: Contrast sensitivity and disability glare were determined in 33 eyes of 33 patients with dry eye and 30 eyes of 30 healthy control subjects for six target sizes with a visual angle of 6.3–0.7 degrees using the Contrast Glaretester 1000, whose working mechanism is similar to that of the conventional perimetry instrument.
Results: Contrast sensitivity was significantly worse in dry eye group when viewing all target sizes (reduction of 0.10–0.25 log contrast units, p < 0.01) except at 6.3 degrees. In the presence of glare, differences in log contrast sensitivity between the groups (0.10–0.25 units) were significant (p < 0.01) for all target sizes, with the dry eye group showing worse results. The reduction in contrast sensitivity induced by glare (disability glare) was significantly worse in the dry eye group versus the control group but only for the 2.5‐degree size target, where 0.14 log contrast units were lost.
Conclusions: Contrast sensitivity with and without glare was significantly reduced in patients with dry eye compared with control subjects, but the number of log contrast units lost with glare (disability glare) was similar in the two groups, except for the 2.5‐degree size target.</description><identifier>ISSN: 1395-3907</identifier><identifier>EISSN: 1600-0420</identifier><identifier>DOI: 10.1111/j.1600-0420.2006.00671.x</identifier><identifier>PMID: 16879576</identifier><language>eng</language><publisher>Oxford, UK: Blackwell Publishing Ltd</publisher><subject>Adult ; contrast sensitivity ; Contrast Sensitivity - physiology ; Diagnostic Techniques, Ophthalmological ; disability glare ; dry eye ; Dry Eye Syndromes - physiopathology ; Female ; Glare ; Humans ; Male ; quality of vision ; Vision Disorders - physiopathology</subject><ispartof>Acta ophthalmologica Scandinavica, 2006-08, Vol.84 (4), p.527-531</ispartof><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c4161-6afd4e9fdcea90dd896c63041e1eb460325efc1461b20eee00f65200894e89db3</citedby><cites>FETCH-LOGICAL-c4161-6afd4e9fdcea90dd896c63041e1eb460325efc1461b20eee00f65200894e89db3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fj.1600-0420.2006.00671.x$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fj.1600-0420.2006.00671.x$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,780,784,1416,1432,27923,27924,45573,45574,46408,46832</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/16879576$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Puell, María C.</creatorcontrib><creatorcontrib>Benítez‐del‐Castillo, José M.</creatorcontrib><creatorcontrib>Martínez‐de‐la‐Casa, José</creatorcontrib><creatorcontrib>Sánchez‐Ramos, Celia</creatorcontrib><creatorcontrib>Vico, Eva</creatorcontrib><creatorcontrib>Pérez‐Carrasco, María J.</creatorcontrib><creatorcontrib>Pedraza, Constanza</creatorcontrib><creatorcontrib>Del‐Hierro, Almudena</creatorcontrib><title>Contrast sensitivity and disability glare in patients with dry eye</title><title>Acta ophthalmologica Scandinavica</title><addtitle>Acta Ophthalmol Scand</addtitle><description>.
