Study: The search for hormonal links goes on...

This one found no differences in testosterone levels amongst women with and without dry eye.

Total testosterone level in postmenopausal women with dry eye

Duarte MC et at, Arg Bras Oftalmol. 2007 May-Jun;70(3):465-9

PURPOSE: The purpose of this study was to compare total testosterone blood level among three groups of postmenopausal women: control, mild to moderate dry eye and severe dry eye.
METHODS: Twenty-nine postmenopausal women were selected. The exclusion criteria were: hormone replacement therapy in the last 8 weeks, mechanical palpebral abnormalities, pterygium, lacrimal obstructions, intraocular inflammation or contact lens use. A blood sample was collected for total testosterone level determination, and the patients were submitted to an ophthalmologic examination (emphasizing on dry eye detection) and answered the OSDI (Ocular Surface Disease Index) questionnaire. Five patients were excluded. Postmenopausal women were divided into three groups according to OSDI score and the ophthalmic examination.
RESULTS: Five patients were classified in the no dry eye group (control), fifteen in the mild to moderate dry eye group and four in the severe dry eye group. There were no statistically significant differences regarding mean age (p=0.3915); instruction level (p=0.9333); number of comorbidities (p=0.2551); medication taken (p=0.2844) and total testosterone level among those groups (p=0.1275).
CONCLUSION: Further research with a greater bigger sample is necessary to establish the relation of androgen levels in dry eye patients.
