Abstract

Purpose

To assess morphological changes in the meibomian glands (MGs) pre- and post-hematopoietic stem cell transplantation (HSCT).

Methods

Participants yet to undergo HSCT were included in a pre-HSCT group. Meibography images of both lids were graded using Pult's meiboscale and analyzed using a semi-automatic software program. Meibography variables in the pre-HSCT group were compared with those in a control group of healthy participants. The follow-up group, a subset of the pre-HSCT group, comprised participants followed up for at least 6 months post-HSCT. Ocular Surface Disease Index (OSDI), tear break-up time, corneal fluorescein staining, and Schirmer test were performed. The differences in meibography variables and ocular surface tests pre- and post-HSCT were analyzed.

Results

Pre-HSCT and control groups comprised 181 and 24 participants, respectively. The pre-HSCT group had a higher meiboscale in the lower lid (2 vs. 1, p = 0.011) than controls. The follow-up group comprised 20 patients followed up for 12.75 months post-HSCT. After HSCT, the meiboscale of the upper lid was higher (2 vs. 1, p = 0.011), the MG area was lower in both lids (upper lid = 16.14 % vs. 21.49 %, p = 0.001; lower lid = 11.92 % vs. 17.59 %, p = 0.011), and the OSDI increased (15.2 vs. 26.85, p = 0.018) in the second visit compared to the first visit.

Conclusions

Alterations in meibography were observed in patients pre- and post-HSCT. This may be attributed to the effect of treatments administered pre-HSCT, although an additive effect of conditioning regimen in the long-term cannot be discarded.

期刊介绍： The Ocular Surface, a quarterly, a peer-reviewed journal, is an authoritative resource that integrates and interprets major findings in diverse fields related to the ocular surface, including ophthalmology, optometry, genetics, molecular biology, pharmacology, immunology, infectious disease, and epidemiology. Its critical review articles cover the most current knowledge on medical and surgical management of ocular surface pathology, new understandings of ocular surface physiology, the meaning of recent discoveries on how the ocular surface responds to injury and disease, and updates on drug and device development. The journal also publishes select original research reports and articles describing cutting-edge techniques and technology in the field. Benefits to authors We also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.
