Studies on the Tear Film in Climatic Droplet Keratopathy and Pterygium

The Anatomical Dry Eye <br/>—A Different Form of Ocular Surface Disease Deserves Focus

“…It does not consider the pathophysiology of the lids such as described by Taylor outlining discontinuity of the marginal tear strip in association with early break up time due to conjunctival scarformation (Taylor 1980) [11]. Nevertheless, it is here that corneas micro-anatomy does correlate to perceived dry eye complaint after cataract …”

Study on Tear Function Abnormality in Pterygium

“…They found normal basal tear secretion in Schirmer’s test [20]. Taylor [1]compared patients with and without pterygium or climatic droplet keratopathy for tear function abnormalities and found no significant difference with regard to Schirmer’s or BUT tests. He found only an abnormality in marginal tear strip and concluded that this abnormality is due to the decrease in tear volume of the conjunctival sac and a change in surface tension.…”

“…These theories have been supported by epidemiologic studies – pterygia appearing to occur more frequently in hot, dry climates – and by clinical and biochemical studies of the tear film [6, 9]. There are few studies concerning the role of tear film in the pathogenesis of pterygia [1]. Our results using three tests to evaluate tear functions do not support the hypothesis stating that tear film abnormality plays the main role in pterygium formation [9, 22].…”

Tear functions in patients with pterygium

“…Tear function abnormalities have been proposed as an etiologic factor due to the observation that a pterygium is further exacerbated by elevation of pterygium head, dryness and dellen formation (Coroneo 1993). No abnormalities in Schirmer's test, tear break-up time or rose bengal staining of the cornea were found in eyes with pterygia (Biedner et al 1979;Taylor 1980;Jensen 1982). It has been suggested that drying of the tear film by wind, devitalized tissues of the medial third of the palpebral aperture and this allowed actinic radiation damage to the conjunctival and corneal epithelium and Bowman's membrane (Coroneo 1993).…”
