Rosacea: Everything you need to know about the ocular form.

Ocular rosacea is a form of rosacea that affects the eyes, making them red, watery, dry, and sensitive. It often affects individuals with a skin form of rosacea, although this is not always the case. In this article, we will explore the symptoms, causes, and ways to treat this eye disorder.

What is ocular rosacea?

Affecting nearly 415 million people worldwide, the rosacea is a chronic disease characterized primarily by the appearance of continuous and diffuse redness on the face. Its symptoms are generally exacerbated by exposure to heat, sunlight, stress, or by the consumption of spicy foods.

It is estimated that about 30 to 50% of cases of skin rosacea are accompanied by an impact on the eyes. It can also happen that ocular rosacea appears first, causing symptoms at the level of the eyes before affecting the facial skin. Finally, it is also possible to suffer from ocular rosacea alone, without skin symptoms.

Ocular rosacea is an inflammatory condition that manifests itself through redness, tearing, itching, and burning sensations. This eye disorder is among the common conditions affecting the surface of the eyes. The eyelids appear swollen, and the eyes are red and dry. They are also particularly sensitive to light. Ocular rosacea also causes the dilation of small blood vessels in the white area of the eye (sclera), making them visible.

Ocular rosacea can develop at any age, however, it is often diagnosed after the age of 30. Statistics also show that women are twice as likely to be affected by rosacea as men, although this phenomenon is not clearly explained.

What are the causes of ocular rosacea?

To date, scientists still do not know the exact causes of rosacea. However, they have found that the majority of people with ocular rosacea have blocked or dysfunctional sebaceous glands, the Meibomian glands. Located at the base of the eyelids, they normally contribute to the lubrication of the eyes by secreting an oily substance. The loss of their function is the cause of the dry eye observed in patients. In addition, when they are blocked, the area surrounding them can swell and become irritated. This leads to redness, itching, or feelings of discomfort in the eyes.

There are other hypotheses regarding the origin of ocular rosacea. It is notably suggested that this pathology could be caused by the proliferation of mites living in the hair follicles of the face and eyelashes, known as Demodex. Colonization by these parasites could potentially block the Meibomian glands, leading to their dysfunction. Furthermore, the Demodex secrete proteases, enzymes involved in protein degradation, which stimulate the activity of PAR-2 (Protease-Activated Receptor) receptors present in the epidermis and play a central role in inflammatory and nociceptive processes. This activation subsequently triggers the release of TNF-α and interleukin-1 (IL-1), inflammatory agents. These agents are responsible for the redness and inflammation of the eyelids observed in individuals suffering from ocular rosacea.

Finally, it could have a genetic origin. Indeed, up to 30% of people with rosacea have a family history of this condition, leading researchers to believe that unidentified genes could be involved and that, in some cases, it could be a rosacea that is inherited. One hypothesis being considered is the prevalence among people suffering from rosacea of certain receptors involved in inflammatory and nociceptive mechanisms. Moreover, it seems that people with light phototypes are more likely to be affected by this disorder.

How to treat ocular rosacea?

Given that this is a chronic condition, there is no definitive curative treatment. Therefore, it is important to repeat the care described below to alleviate symptoms. The first step is daily eyelid massage to evacuate the substance accumulated in the Meibomian glands, which is responsible for their blockage. This is sometimes enough to restore their function, leading to the disappearance of inflammation and reducing dry eye. However, in most cases, massages must be combined with medical treatment. The most common ones are:

  • The administration of antibiotics.

    The standard treatment is based on tetracyclines. These antibiotics work by inhibiting the synthesis of proteins necessary for bacterial growth, thereby preventing bacterial proliferation. They are effective against most symptoms of ocular rosacea (inflammation around the eyes, conjunctivitis, dry eye), and also have anti-inflammatory properties . They regulate the secretions of the Meibomian glands. In cases where tetracyclines are contraindicated, macrolides, which are antibiotics that inhibit bacterial multiplication, are generally used.

  • The use of antibiotic eye drops or ointment.

    The application of an antibiotic ointment helps to limit the growth of bacteria on the eyelids. To maximize its effect, it is best to combine its application with eyelid massage. The use of eye drops, on the other hand, reduces ocular inflammation and conjunctivitis.

  • Artificial tears.

    The administration of artificial tears helps to alleviate dry eye present in nearly 100% of patients suffering from rosacea.

As soon as the first symptoms of ocular rosacea appear, it is very important to consult an ophthalmologist.
