Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Purpose. To quantitatively assess the staining of Marx's line with lissamine green dye. Methods. Forty white (European) subjects, aged 18 to 78 years, were assessed. The subjects had no major eye disease, although some had mild to moderate blepharitis. Lissamine green dye strips were used to stain the marginal zone of the palpebral conjunctiva, and high-magnification photo slit lamp images were taken of the everted upper eyelid along with a scale rule. From prints at 1600x, the distances between the main tarsal (Meibomian) gland orifices, the width of the lissamine green-stained Marx's line, and the location of its anterior border were measured. Results. The group-mean distance between the main tarsal gland orifices was 0.81 ± 0 16 mm, whereas the width of the lissamine green-stained line was 0.10 ± 0.09 mm. In most subjects, the lissamine green-stained line was posterior to the tarsal gland orifices, and the location of the proximal (anterior) edge of this line averaged +0.13 mm from a reference line drawn through the orifices. Conclusion. Lissamine green dye highlights a very distinct line of cells along the marginal zone. This line of cells is narrow and is thought to be the natural site of frictional contact between the eyelid margin and the surfaces of the bulbar conjunctiva and cornea, rather than the edge of the tear meniscus or location of the edge of the lacrimal river.
