PURPOSE: To evaluate the effects of dissolvable collagen punctal plugs on the symptoms, tear stability and volume in aqueous deficient dry eyes. METHODS: Sixty-two aqueous deficient dry eye patients of mixed aetiology underwent lacrimal punctal occlusion with dissolvable collagen plugs. The subjects were randomly allocated to one of two treatment groups: group I (n = 36) had their lower puncta occluded and group II (n = 26) had both their upper and lower puncta occluded. The effectiveness of this treatment was clinically assessed by (1). scoring subject symptoms and (2). measuring the tear parameters of tear thinning time (TTT) and tear meniscus height (TMH) as indicators of tear stability and volume, respectively. Following baseline measurements, patients were reviewed at time intervals of 5 and 12 days post-occlusion. A group of age- and gender-matched normals (n = 45) was recruited for comparison (group III). RESULTS: Tear volume and stability were significantly higher in group III compared with I and II at baseline. In the treated groups on both days 5 and 12: (1). symptom score reduced significantly from a median value of 7 to 3 (p = <0.001); (2). tear stability increased significantly from a median value of 3 to 5 s by day 5 (p 相似文献

Treatment of keratoconjunctivitis sicca with topical androgen 总被引:6,自引:0,他引:6
Objective: Androgens have been reported to influence lipid production of sebaceous glands and even many ocular tissues. The effect of topical androgen therapy on a 54-year-old patient with keratoconjunctivitis sicca (KCS) and decreased lipid phase of the tear film is reported. Methods: For assessment of the lipid phase of the tear film, break up time (BUT) and lipid layer thickness (LLT) were monitored during 6 months before treatment as well as 3 months while using a daily topical androgen therapy. Results: During the topical androgen therapy the pathological lipid phase of the tear film was completely restored indicated by the normalisation of the values of BUT and LLT. Conclusion: These findings are consistent with animal experiments indicating that topical administered androgen can restore the decreased lipid phase of the tear film. This may open up new therapeutic strategies for KCS. 相似文献

OBJECTIVE: The purpose of this study was to compare the discriminative properties of two generic health-related quality of life (QoL) instruments (SF-36 and EQ-5D) and a newly developed disease-specific patient-reported outcomes instrument (Impact of Dry Eye on Everyday Life (IDEEL)) to distinguish between different levels of dry eye severity. METHODS: Assessment of 210 people: 130 with non-Sjogren's Keratoconjunctivitis Sicca (non-SS KCS), 32 with Sj?gren's Syndrome (SS) and 48 controls; comparison of SF-36, EQ-5D, and IDEEL age-adjusted data by dry eye severity levels. Severity was assessed based on diagnosis (non-SS KCS, SS, control), patient-report (none, very mild, mild, moderate, severe, extremely severe) and clinician-report (none, mild, moderate, severe). RESULTS: Discriminative validity results were consistent for all instruments. Significant differences between severity levels were found with most SF-36 scales (P < 0.05), all EQ-5D scales (P < 0.05), and all IDEEL scales (P < 0.0001), except for Treatment Satisfaction. IDEEL scales consistently outperformed the generic QoL measures regardless of the severity criterion used. Most SF-36 scales outperformed the EQ-5D QoL scale, but the EQ-5D visual analog scale outperformed the SF-36 scales, except for General Health Perceptions. CONCLUSIONS: The disease-specific IDEEL scales are better able to discriminate between severity levels than the majority of the generic QoL scales. Preliminary evidence demonstrates that the IDEEL will be sensitive to QoL changes over time, although further testing in controlled longitudinal studies is needed. 相似文献

Purpose
Results from a 6-month double-masked and a 6-month open-label study (SANSIKA) established the efficacy and safety of once-daily 0.1% cyclosporin A cationic emulsion (CsA CE) in severe keratitis due to dry eye disease (DED). This article presents results from the Post-SANSIKA study, a 24-month extension of SANSIKA assessing the sustained efficacy of CsA CE after treatment discontinuation.Methods
Time to relapse (corneal fluorescein staining [CFS] score ≥4 [modified Oxford scale]) was assessed after treatment discontinuation in patients from the SANSIKA study who had CFS improvement from a score of 4 to ≤2 after 6 or 12 months of treatment with CsA CE.Findings
Of 62 patients who achieved a CFS score ≤2 at the end of the SANSIKA study, 38 did not relapse and 24 (39%) relapsed during the 24-month period after CsA CE discontinuation; the latter (relapse) group comprised 35% of patients initially treated with CsA CE for 12 months in SANSIKA versus 47% of those treated for 6 months only. Patients spent the most time during the extension study at CFS scores of 1 or 2 (median duration of 8.5 weeks and 14.7 weeks per year, respectively), indicating marked improvement, and less time at scores of 3, 4, or 5 (median time, 2.0 weeks, 0 weeks, and 0 weeks per year). Of 23 patients eligible for safety analysis (ie, patients who received the study treatment at least once), 12 (52.2%) reported a total of 26 ocular adverse events (AEs). Among these, 5 ocular AEs, reported in 5 patients (21.7%), were considered related to study treatment: 3 events of mild instillation site pain in 3 patients (13.0%) and eye discharge and foreign body sensation, each reported in 1 patient (4.3%). Only 1 systemic AE (nasal congestion), reported in 1 patient (4.3%), was considered related to study treatment. None of the AEs led to treatment discontinuation.Implications
The majority of patients who discontinued CsA CE after experiencing DED improvement in the SANSIKA study did not experience a relapse in this 24-month follow-up study; these patients spent the most time at CFS scores consistent with marked improvement. CsA CE had a favorable safety/tolerability profile over 2 years. Treatment for up to 12 months with CsA CE provides sustained improvements in patients with severe keratitis due to DED.

We have evaluated transplantation of reduced submandibular glands for the treatment of severe keratoconjunctivitis sicca. Thirty-four rabbits were allocated into three groups: dry eye (controls, n=10), transplantation of whole submandibular glands (n=12), and transplantation of reduced submandibular glands (n=12). Outcome measures included the results of Schirmer's test and the Rose Bengal test, and histological examination of the cornea and the transplanted gland. Volume of tears significantly increased after transplantation of the whole gland, but did not change after transplantation of the reduced gland compared with dry eyes induced preoperatively. Neither transplantion group had keratoconjunctivitis sicca postoperatively. There were no histological abnormalities in the transplanted tissues. The results that the surgical technique of using reduced submandibular glands for transplantation was feasible, and that the secretion from the reduced gland was similar to that from a normal lacrimal gland. In conclusion, transplantation of a reduced submandibular glands is feasible in the treatment of keratoconjunctivitis sicca. 相似文献

ObjectivesTo assess associations between ophthalmological features and the main systemic biomarkers of primary Sjögren's Syndrome (pSS), and to identify systemic biomarkers associated with severe keratoconjunctivitis sicca (KCS) in pSS patients.MethodsIn this cross-sectional study, data was retrospectively extracted from the monocentric cohort of the French reference centre for pSS. We analysed data from the initial visit of patients admitted for suspicion of pSS and included patients validating pSS ACR/EULAR classification criteria. Ophthalmological assessment included Schirmer's test, tear break-up time, ocular staining score (OSS), and visual analogue scale (DED-VAS) for dry eye disease (DED) symptoms. Results of minor salivary gland biopsy, unstimulated whole salivary flow rate, anti-SSA/Ro antibodies, anti-SSB/La antibodies, and rheumatoid factor (RF) were collected.ResultsA total of 253 patients (245 females) with confirmed pSS, aged 56.6 ± 13.0 years, were included, among which 37% had severe KCS. Multivariate analysis showed that the presence of anti-SSA/Ro antibodies, anti-SSB/La antibodies and RF were associated with conjunctival OSS (odds ratio–OR– = 1.25 per OSS unit increase; confidence interval–CI–95% = 1.05–1.49; P = 0.01; OR = 1.31 per OSS unit increase; CI95% = 1.09–1.58, P = 0.002, and OR = 1.34 per OSS unit increase; CI95% = 1.12–1.59; P = 0.001, respectively). Both anti-SSB/La antibodies and DED-VAS ≥ 5 were significantly associated with severe KCS (OR = 2.03; CI95% = 1.03–4.00; P < 0.05 and OR = 2.52, CI95% = 1.31–4.90; P < 0.01, respectively).ConclusionAssociation between conjunctival OSS and systemic biomarkers of pSS indicate the crucial importance of conjunctival staining when pSS is suspected as a cause of DED. Conversely, patients with anti-SSB and DED-VAS ≥ 5 features should be prioritized for extensive evaluation by an ophthalmologist due to their association with severe KCS. 相似文献
