[Treatment of chronic posterior blepharitis after allogeneic hematopoietic stem cell transplantation (a case report)].

After allogeneic hematopoietic stem cell transplantation (allo-HSCT), various eye diseases are detected in 30-60% of patients, with chronic graft-versus-host reaction - in 50-90% of patients. Among the complications, the most frequent is damage to the eye surface and eyelids. The article presents a clinical case of successful minimally invasive treatment of chronic posterior blepharitis in a patient who has undergone allogeneic hematopoietic stem cell transplantation. Normalization of the outflow of meibomian gland secretion after the medical procedure was a prerequisite for improving the quantitative and qualitative composition of the lipid layer of the tear film and a factor contributing to a decrease in the amplitude of inflammation, which is reflected in the clinical and functional results.
