Measurement Requirements

This trial is evaluating whether Treatment will improve 1 primary outcome and 4 secondary outcomes in patients with Meibomian Gland Dysfunction. Measurement will happen over the course of Baseline to 3 months..

Personal Health Questionnaire (PHQ-9)
Personal Health Questionnaire - a brief anxiety and depression questionnaire. Will be used in this study to evaluate the interaction between depression/anxiety and response to treatment.
Dry Eye Questionnaire 5 (DE-5)
Dry eye questionnaire 5 - used to evaluate the degree of dry eye symptoms. Scores range from 0-22. A score of 0 represents the minimum dry eye symptoms someone may have and a score of 22 represents the maximum dry eye symptoms someone may have.
Ocular Surface Disease Index (OSDI) Questionnaire
Ocular surface disease index - used to evaluate the degree of dry eye symptoms. Scores will range from 0 to 48, where 48 indicates severe dry eye.
Ocular surface microbiome testing
To evaluate the composition of the ocular surface microbiome using Shannon's diversity index. The alpha diversity (local species pool) of the population will be analyzed and compared pre-and post-treatment within and between the azithromycin and control groups. The difference between the bacterial microbiome in the azithromycin and placebo arm will be assessed using a PERMANOVA with an L2 norm distance measure. Secondary analyses will include L1 and L0 norms, as well as a phylogenetic distance. In addition, we will assess whether bacterial alpha diversity is decreased in the antibiotic treated arm with the primary outcome being the Simpson's index (L2), with secondary analyses assessing Shannon's (L1) and Richness (L0).
Neuropathic Pain Inventory for the Eye (NPSI-E)
Neuropathic pain inventory for the eye - used to study neuropathic vs stimulatory eye pain.

What is meibomian gland dysfunction?

Maintaining integrity of the meibomian gland is critical to preserve the function of the gland. If this integrity is impaired by smoking, the symptoms may be increased in the eyes. The condition is not only a cosmetic problem but also a health concern. It is not caused by a viral infection such as herpes simplex nor from a genetic predisposition to a disorder. It can be a health problem which increases the risks associated with smoking. Smoking causes irritation to the eyes (dry eyes syndrome), itchiness and irritation (hay fever), increased tearing and discharge (globus gland) and nasal congestion and sinus and ear congestion (this can be due to sinusitis).

What are the common side effects of treatment?

There is extensive data regarding treatment strategies to prevent, diagnose, and treat ODD. However, the most common side effects are not described, and therefore it is essential to know what side effects commonly occur during treatment in order to manage them and prevent their occurrence.

Anonymous Patient Answer

Is treatment typically used in combination with any other treatments?

Although no treatment has shown cure, many effective patients have good quality of life and good response to treatments and steroids. However, no one has an effect comparable to the other treatments. The best choice of treatment for a particular patient with Sjögren syndrome, which depends on the particular patient, has to be determined by a doctor in a consultation before starting treatment to be tailored by the patient as well as the general practitioner or ophthalmologist. Every patient's profile and previous successful treatments are taken into account when designing a treatment strategy.

Is treatment safe for people?

The most common side effects to treatment in those prescribed the product, of the four available drops, included dry eye, itching, and irritation. The majority of side effects were minor and usually resolved by 15 days. In no case did side effects cause discontinuation of treatment. The treatment of blepharitis appears to be safe for people prescribed the product and who have blepharitis symptoms and is well tolerated. Overall, this is a short-term treatment where the patient has to keep taking the treatment in the way described in the instructions.

What is the average age someone gets meibomian gland dysfunction?

When patients are treated with the same surgical and non-surgical methods, the median age of symptoms presentation was 37 years (range: 17-82). Patients who present with symptoms after 42 years of age (95th centile) typically have the disorder related to a family history or have had a surgical procedure that has damaged the tear sac. There was no significant differences in the mean age of symptom onset, symptom severity, or age at intervention by gender or surgical approach - a significant improvement in surgical outcomes. Recent findings of this study suggest that people who present with symptoms ≤42 years have a similar likelihood of having MGD related to a family history or prior surgical intervention for other ocular problems.

What is treatment?

In this review, both medications and meibomian gland surgery have yielded satisfactory relief of meibomian gland dysfunction. Many patients require more than 1 treatment modality. Although the efficacy of meibomian gland surgery is unknown at this time, it may be the future. Nevertheless, the advantages of each individual therapy should be reviewed thoroughly and weighed against its costs and risks.
