Purpose

To evaluate the preliminary long-term efficacy of diquafosol ophthalmic solution for aqueous-deficient dry eye.

Methods

Fifteen patients with mild-to-moderate aqueous-deficient dry eye were enrolled. After a washout period, the patients were treated with 3 % diquafosol ophthalmic solution for 6 months. We assessed 12 subjective dry eye symptoms, corneal and conjunctival staining with fluorescein, tear film break-up time (BUT), lower tear meniscus height measured with anterior-segment optical coherence tomography, Schirmer’s testing, and adverse reactions at baseline and 1, 3, and 6 months after the start of treatment.

Results

Treatment with diquafosol ophthalmic solution significantly improved dry eye symptoms, corneal staining, BUT, and tear meniscus height at 1 month and maintained the effectiveness for 6 months. Conjunctival staining significantly improved 3 and 6 months after treatment. No significant adverse reactions developed.

Conclusions

Prolonged use of diquafosol ophthalmic solution for 6 months produced significant improvement both subjectively (dry eye symptom score) and objectively (ocular staining score and tear function tests) for aqueous-deficient dry eye.  相似文献

AIM: To investigate the effectiveness of diquafosol ophthalmic solution 3% administered in Korean patients with dry eye disease in real-world clinical settings. METHODS: Diquafosol was administered for 8wk to 3 patient groups who received diquafosol as add-on therapy to existing medication (Add group, n=150); received diquafosol only (Monotherapy group, n=196); or discontinued part of their existing medication in favor of diquafosol (Switch group, n=11). Tear break-up time (TBUT), cornea and conjunctival staining based on National Eye Institute/Industry scoring scheme, subjective symptoms using the Ocular Surface Disease Index (OSDI) questionnaire, and meibum quality and expressibility were evaluated at baseline, week 4, and week 8. RESULTS: The mean TBUT increased (from 3.46, 3.92, and 5.84s, respectively, to 5.15, 5.53, and 8.59s, respectively) and corneal staining score decreased (from 2.23, 2.24, and 3.09, respectively, to 0.85, 0.97, and 1.64, respectively) in a time-dependent manner from baseline to week 8 in all three groups. Conjunctival staining score, OSDI questionnaire, and meibum quality and expressibility improved over time from baseline to week 8 in the Add and Monotherapy groups, but differences were not statistically significant in the Switch group. CONCLUSION: Diquafosol improves subjective symptoms and objective signs in patients treated with existing medicines combined with diquafosol and treated solely with diquafosol. Diquafosol can be used as an effective therapeutic agent for dry eye disease or additionally applied in patients who have insufficient response to existing medicines.  相似文献

AIM: To evaluate the quantitatively changes in lipid layer thickness (LLT) when 3% diquafosol eye drop is used for dry eye patients using the tear film interferometer. METHODS: A total 124 participants (32 males, 92 females; mean age, 28.9y) diagnosed with dry eye disease (DED) received topical instillation of 4 ophthalmic solutions in one eye: diquafosol, normal saline, 0.1% sodium hyaluronate and 0.3% gatifloxacin, in a masked manner. LLT was measured using an interferometer at baseline and 20min after the instillation of each ophthalmic solutions. RESULTS: Changes of LLT after instillation (nm, mean± standard error) were as follows: 12.6±2.0 for diquafosol (P<0.001), 1.2±2.2 for normal saline (P=0.301), 1.5±2.0 for hyaluronate (P=0.495), and 0.5±3.2 for gatifloxacin (P=0.884). CONCLUSION: Topical instillation of diquafosol increases tear film LLT in DED patients. Diquafosol 3% eye drop might be effective treatment option of evaporative DED with meibomian gland dysfunction.  相似文献

Purpose

To assess the additive effect of diquafosol tetrasodium on sodium hyaluronate monotherapy in patients with dry eye syndrome.

Methods

This study evaluated 64 eyes of 32 patients (age: 62.6±12.8 years (mean±SD)) in whom treatment with 0.1% sodium hyaluronate was insufficiently responsive. The eyes were randomly assigned to one of the two regimens in each patient: topical administration of sodium hyaluronate and diquafosol tetrasodium in one eye, and that of sodium hyaluronate in the other. Before treatment, and 2 and 4 weeks after treatment, we determined tear volume, tear film break-up time (BUT), fluorescein and rose bengal vital staining scores, subjective symptoms, and adverse events.

Results

We found a significant improvement in BUT (P=0.049, Dunnett test), fluorescein and rose bengal staining scores (P=0.02), and in subjective symptoms (P=0.004 for dry eye sensation, P=0.02 for pain, and P=0.02 for foreign body sensation) 4 weeks after treatment in the diquafosol eyes. On the other hand, we found no significant change in these parameters after treatment in the control eyes.

Conclusions

In dry eyes, where sodium hyaluronate monotherapy was insufficient, diquafosol tetrasodium was effective in improving objective and subjective symptoms, suggesting its viability as an option for the additive treatment of such eyes.  相似文献

PURPOSE: To investigate the safety and efficacy of diquafosol tetrasodium, a P2Y2 receptor agonist that stimulates fluid and mucin secretion on the ocular surface, as a novel topical treatment of dry eye disease. METHODS: Subjects with dry eye (n=527) were evaluated in a randomized, double-masked, parallel-group trial comparing 24 weeks of treatment with 2 concentrations of diquafosol (1% and 2%) versus placebo instilled 4 times daily. Corneal staining, conjunctival staining, Schirmer tests, and subjective symptoms of dry eye were evaluated. Use of artificial tears was permitted as necessary. RESULTS: Subjects treated with 2% diquafosol had significantly lower corneal staining scores compared with placebo at the 6-week, primary efficacy time point (P<0.001), and superiority continued throughout the 24-week study. Reductions in corneal staining were observed as early as after 2 weeks of treatment, were maintained throughout the 24-week study, and were observed to worsen slightly (toward baseline) when diquafosol treatment was discontinued (week 25). Results for conjunctival staining were consistent with those observed for corneal staining. Schirmer scores at week 6 were significantly higher with diquafosol treatment than with placebo (P相似文献
