Efficacy of artificial tears containing trehalose and hyaluronic acid for dry eye disease in women aged 42-54 versus ≥ 55 years.

BACKGROUND AND OBJECTIVES: Dry eye disease (DED) is common in postmenopausal women. This study evaluated efficacy of a 3-month daily treatment with artificial tears containing trehalose and hyaluronic acid (HA) in women aged 42-54 years (mixed-hormonal status) versus ≥ 55 years (postmenopausal) and with moderate and severe DED. METHODS: This was a post-hoc analysis of three clinical trials assessing the efficacy of artificial tears containing trehalose (3%) and HA (0.15%) in women with an Ocular Surface Disease Index (OSDI) ≥ 18. Patients instilled one drop of the artificial tears in each eye 3 to 6 times daily and were evaluated at baseline and after 84 ± 7 days for DED symptom severity (OSDI), hyperemia (McMonnies scale), tear break-up time (TBUT), corneal and conjunctival staining (Oxford and Van Bjisterveld scales), tear production (Schirmer I test), and ocular symptoms. RESULTS: A total of 273 women were evaluated, 61 of age 42-54 years; 212 of ≥ 55 years. DED symptoms, as measured by the OSDI, decreased significantly with the treatment in both age groups (p < 0.0001). Conjunctival hyperemia decreased significantly and TBUT increased significantly in both groups, especially in women of age 42-54 (both p < 0.0001). The global (corneal and conjunctival) staining score decreased significantly in both groups, but also more in women of age 42-54 years. No differences were observed between age groups for any of the variables measured, except for visual acuity. DED symptoms were consistently reported more frequently by the mixed hormonal status women, but also the effect of the treatment was more pronounced in this group. CONCLUSIONS: Artificial tears with trehalose and HA significantly improved the symptoms of DED in women aged 42-54 and ≥ 55 years. The decrease in symptoms was more pronounced in women of age 42-54 years, suggesting better mechanisms of recovery from inflammation and loss of ocular surface homeostasis.

Effects of 3% trehalose as an adjuvant treatment after LASIK.

PURPOSE: To evaluate the effect of 3% trehalose as an adjuvant in the standard treatment after laser-assisted in situ keratomileusis. DESIGN: Interventional prospective comparative single-blind study. SETTING: Department of Ophthalmology, Hospital Quirón Zaragoza, Spain. METHODS: A total of 26 eyes (13 patients) were included, of which 12 eyes (group 1) received conventional treatment with lubricant drops of hyaluronic acid (0.15%) and 14 eyes (group 2) received, additionally, an ophthalmic solution of 3% trehalose. Pre- and postoperative quality-of-life tests and vital stains, tear breakup time, and osmolarity measurements were made. RESULTS: We obtained statistically significant differences between the groups in the Symptom Assessment in Dry Eye test in all visits with respect to severity, and in the postoperative day 1 visit with respect to frequency, in all cases favoring the trehalose treatment. The values of osmolarity were not significantly different between groups. However, we did find significant differences in the Oxford scale in day 90 for the trehalose treatment (P<0.001), and in the National Eye Institute scale in day 30 (P=0.02). CONCLUSION: The results of this exploratory study indicate that the adjuvant treatment with 3% trehalose could be superior with respect to the standard treatment, with improvements in the objective and subjective parameters of tear quality.

Topical tacrolimus ointment for treatment of intractable atopic keratoconjunctivitis: a case report and review of the literature.

PURPOSE: To report the utility of tacrolimus 0.03% dermatologic ointment (Protopic) in a case of refractory atopic keratoconjunctivitis with giant papillae. A review of the medical literature is presented. METHODS: A 32-year-old man with a long-standing history of severe atopic disease was referred to our department because of bilateral intense eye pain, itching, photophobia, and epiphora. Biomicroscopy examination showed conjunctival hyperemia, superficial punctata keratitis, and tarsal giant papillae. This patient had undergone previous treatment with systemic and topical steroids, antihistamines, topical antihistamine/mast cell stabilizer drops, cyclosporine A, and even surgical resection-cryopexy of giant papillae-without success. RESULTS: The patient was started on tacrolimus 0.03% ointment treatment of the conjunctival fornix twice daily. After 2 months, the patient experienced resolution of his clinical symptoms with a significant decrease in papillae size. No side effects were reported. Treatment was continued for 1 month and gradually reduced with increasingly wide intervals between applications. Eight months after treatment, there were no signs of reactivation, and the patient remains asymptomatic. CONCLUSIONS: Application of tacrolimus 0.03% dermatologic ointment into the lower fornix seems to constitute an interesting alternative treatment for atopic keratoconjunctivitis that is refractory to traditional treatment.
