Brief Summary

Mastocytosis is a rare condition characterized by an accumulation of mast cell cells in one or more organs such as the liver, bone marrow, spleen and intestines. Its prevalence in the general population is 1 in 10,000. This pathology is due to the proliferation of a mast cell clone and the excessive release of inflammatory mediators which lead to abnormal tissue infiltration. To date, there are only a few cases reporting ocular and orbital manifestations of mastocytosis. Our prospective, interventional and single-center study consist in describing the ocular functional manifestations and ocular surface abnormalities of patients with systemic and cutaneous mastocytosis.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Have a diagnosis of mastocytosis
  • Male or female, 18 years of age and over
  • Ability to understand and provide written informed consent.

You may not qualify if:

  • Disorders that do not allow good visualization of the posterior pole (cataract, intravitreal hemorrhage)
  • Patients with another ocular pathology that may bias the results (corneal dystrophy, dysthyroid orbitopathy, retinal pathologies)
  • History of refractive surgery
