Summary: | Aim To explore the relationship between serum
concentration of sex hormones and dry eye symptoms
and signs in postmenopausal women.
Methods A cross-sectional analysis was undertaken.
Subjects were 46 postmenopausal women with dry eye
(mean age 64.4±5.2 years, 13.7±6.4 years since
menopause; not undergoing hormone replacement
therapy). Ocular symptoms (Ocular Surface Disease Index
(OSDI) and Ocular Comfort Index (OCI)), tear function
(tear osmolarity, non-invasive tear break-up time, tear
secretion), corneal and conjunctival staining, and
meibomian gland (MG) appearance, were recorded.
Venous blood was collected and serum concentrations of
17β-oestradiol (E2), 3-α-androstanediol-glucuronide
(3α-diol-G), and dehydroepiandrosterone sulfate (DHEAS)
were determined using ELISA. Multiple linear
regression analysis was used to examine predictors of
dry eye symptoms and signs.
Results Mean serum concentration of E2, 3α-diol-G
and DHEA-S was 9.02±13.40 pg/mL, 1.59±1.02 ng/mL
and 0.74±0.53 μg/mL, respectively. Ocular symptoms
were elevated (mean scores 27.0±18.1 (OSDI) and 40.3
±8.4 (OCI)) but signs were within normal ranges. Higher
serum E2 concentration along with capped glands, lid
telangiectasia and older age was a significant predictor
of worse MG secretion quality (p<0.001, R2
adj=0.75).
Serum hormones were not significant predictors of ocular
symptoms in multivariate analysis (p>0.05).
Conclusion Serum oestrogen appears to be a key
factor in MG signs. Although serum hormone levels did
not contribute significantly to dry eye symptoms in this
study, it is possible that oestrogen plays a role through
its effect on meibum secretion. These findings suggest
that MG dysfunction underpins dry eye symptoms in
non-Sjögren’s dry eye in postmenopausal women |
