About this study

Official title: The Effects of Latanoprost, Bimatoprost and Travoprost on Periocular Skin Pigmentation

The purpose of this study is to study changes in skin color that may be caused by using one of the three eye medicines: Xalatan, Travatan or Lumigan.

Read the detailed description

One uncommon side effect of prostaglandin eye drops is a change in color of the skin around the eyes, which is reversible. There are three different brands of the medicine which are equally effective in lowering eye pressure but their likelihood of changing skin color is unknown. Qualifying patients will be randomly assigned to use one of the three eye drops. We will take skin color measurements from several locations on the face over one year to measure pigmentation changes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Extent of Latanoprost, Bimatoprost and Travoprost Induced Periocular Skin Hyperpigmentation Over a One Year Time Course in Newly Diagnosed Primary Open Angle and Ocular Hypertension Patients.

    Periocular skin color was measured with the Minolta Chroma Meter CR-400 and the L*a*b* system, also known as Commission Internationale de l'Eclairage. This is a well-accepted unit of measurement in which L* corresponds to brightness and a* and b* correspond to chromaticity.

    Measurements were taken at baseline and 1 year. Data from each time point and each location (upper and lower eyelids or cheeks/face) were averaged, and subtracted from the baseline value for that location. Six predetermined areas on and around the upper and lower eyelid and 2 areas of the face/cheek were measured.Upper and lower eyelid values were averaged and reported as single value for each location ie;-upper eyelids, lower eyelid and cheek/face. A decrease in luminance indicates increased pigmentation at the site of measurement.

    Measured: one year
