| Blephademodex | Device | During the first 28 days of the trial, subjects will use one Blephademodex® eyelid hygiene wipe every evening per eye to clean the eyelids of both their eyes. At the start of the second period the Investigator will assess based on the GDS if the condition is resolved and manage accordingly: subjects will either continue with this regime if GDS is unchanged (further treatment phase) or revert to Blephaclean wipes every evening instead (maintenance phase), again to clean the eyelids of both their eyes. |
| Measure | Description | Time Frame |
|---|---|---|
| Global Discomfort Score | Change from Baseline at Day 28 The Global (overall) discomfort score (GDS) consists of a single question, which can be answered by the subject by choosing a value between 0 (no discomfort) and 10 (worst discomfort): Thinking about today, how would you rate the discomfort of your eyes? | Day 28 |
| Global Discomfort Score | Change from D28 at Day 56 | Day 56 |
| Measure | Description | Time Frame |
|---|---|---|
| Specific Blepharitis symptoms | Symptoms will be rated by the patient on the day of visit using 10-grade scales (0 = none to 10 = severe) for each of the following items Severity of any eyelid itching today / Severity of lid redness today / Severity of eyelid swelling today / How severe was the eyelid crusting this morning when you woke up? / How severe is missing lashes today? | Day 56 |

| adapted Total Ocular Symptom Score (TOSS) | 8-item questionnaire with an overall score ranging from 0 ("none of the time") to 4 ("all of the time"). It contains of a single question concerning the frequency with which 8 different symptoms (itchy eyelids, eyelid redness, red eyes generally, swollen (puffy) eyes, tearing (eyes watering), crusting around the lashes, burning or stinging sensations and noticed eyelash loss) were experienced in the course of a week. | Day 56 |
| Symptom Assessment in Dry Eye (SANDE) | Comprised of two questions: 1) How often do your eyes feel dry and/or irritated? And 2) How severe you feel your symptoms of dryness and/or irritation are? This questionnaire uses a 100 mm horizontal line as visual analogue scale (VAS) for each question to assess ocular discomfort and/or dryness experienced by the patients. In the SANDE questionnaire, frequency of symptoms ranges from "rarely" to "all of the time" and the severity of symptoms ranges from "very mild" to "very severe". | Day 56 |
| Demodex count | Sideways 'pull' on 10 eyelashes - upper or lower lashes Extent (mites present? yes or no) and Severity/Intensity (1=1 tail; 2=2 tails; 3 =2+tails) | Day 56 |
| Ocular surface redness | Efron scale | Day 56 |
| Lid margin redness/swelling | Efron/custom scale | Day 56 |
| Cylindrical dandruff | Lash line coverage (%) and severity (mild/moderate/severe) | Day 56 |
| Ocular surface staining | Oxford scale; corneal only | Day 56 |
| Physician's impression and patient impression | Answer the item 'the treatment has been sufficiently effective' on a 4-point scale (strongly disagree, disagree, agree, strongly agree) | Day 56 |
| Tolerability of the wipes | Tolerability assessment by the physician and patient (0 = intolerable; 1 = somewhat tolerable; 2 = tolerable; 3 = fully tolerable) | Day 56 |
| Visual acuity | Snellen eye chart | Day 56 |
| Assessment of ease of use | as experienced by the subjects, rated on a five-point scale of "Very Difficult" to "Very Easy". | Day 56 |
