Comparison of Evaporimetry With the Established Methods of Tear Film Measurement

Dry Eye Syndromes

Purpose: To establish whether there is a correlation between dry eye symptoms, age and gender, a difference in symptom intensity in different times of the day, which test (Schirmer or TBUT) better correlates with dry eye symptoms, whether it is possible to reliably use cheap, easy to use hygrometer in everyday clinical setting, and finally whether there is statistically significant correlation between applied tests (TBUT, Schirmer and evaporimetry). Methods: Subjects: 45 in group without dry eye related symptoms, and 45 in group with symptoms. Examination included structured case history (questionnaire), slit lamp examination with fluorescein staining, periocular evaporimetry, TBUT test and Schirmer test.

Burden of Illness and Treatment Assessment of Patients With Dry Eye Disease: A Cross-Sectional Survey...

Dry Eye Disease

This study employed secondary database analysis of the Adelphi Dry Eye Disease (DED) Disease Specific Programme™ (DSP™), a templatized cross-sectional survey with retrospective data collection that is administered by Adelphi to a convenience sample of patients diagnosed with DED, and their consulting physicians in the United States. In addition to the survey data, the DED DSP also included recorded medical history data as reported by physicians (optometrists, ophthalmologists or refractive surgeons).

Influencing Factors on Dry Eye Syndrome and Ocular Surface Disease

Dry Eye SyndromeOcular Surface Disease

Dry eye syndrome and ocular surface disease are very important ophthalmologic diseases. It is known that various inducers are involved. However, it is still necessary to study how influencing factors are related to dry eye syndrome and ocular surface disease and how treatment for dry eye syndrome and ocular surface disease is helpful.

Point of Care Testing of Inflammatory Markers in Tears

Dry Eye Syndrome

To evaluate the use of a point of care device to measure markers of inflammation in various eye conditions. In particular, matrix metalloproteinase-9 (MMP-9) will be measured. MMP-9 is an enzyme that plays a role in inflammation. The value obtained with the point of care device will be correlated with values obtained using gel electrophoresis to measure MMP-9 from the same sample. These data will be compared to clinical exam findings and questionnaires to help the investigators better understand the role of this marker of inflammation in eye diseases and possibly improve diagnostic abilities.
