PurposeTo evaluate the effectiveness of cyclosporine 0.05% for dry eye after cataract surgery. MethodsThirty-two newly diagnosed patients with dry eye syndrome 1 week after cataract surgery received a twice-daily treatment of cyclosporine 0.05% for one eye and normal saline 0.9% for the other. Disease severity was measured at 2 weeks, 1 month, 2 months, and 3 months by Schirmer test I (ST-I), tear film break-up time (tBUT), corneal temperature and dry eye symptom questionnaire (Ocular Surface Disease Index). ResultsBoth groups increased in ST-I and tBUT over time. ST-I in the cyclosporine 0.05% group showed a significant increase at 3 months and tBUT in the cyclosporine 0.05% group showed an increase at 2 and 3 months. The dry eye symptom score was significantly reduced in the cyclosporine 0.05% group. ConclusionsCyclosporine 0.05% can also be an effective treatment for dry eye after cataract surgery. 相似文献

PurposeTo investigate changes in dry eye symptoms and diagnostic test values after cataract surgery and to address factors that might influence those symptoms and test results. MethodsTwenty-eight eyes from 14 patients with preoperative dry eye (dry eye group) and 70 eyes from 35 patients without preoperative dry eye (non-dry eye group) were studied prospectively. In each group, we measured values such as tear break-up time (tBUT), Schirmer I test (ST-I), tear meniscus height (TMH), and subjective dry eye symptoms (Sx), and evaluated the postoperative changes in these values. We also evaluated the influence of corneal incision location and shape on these values. The correlations between these values and microscopic light exposure time and phacoemulsification energy were investigated. ResultsIn the dry eye group, there were significant aggravations in Sx at 2 months postoperatively and in TMH at 3 days, 10 days, 1 month, and 2 months postoperatively, compared with preoperative values. All dry eye test values were significantly worse after cataract surgery in the non-dry eye group. With regard to incision location, there was no difference in tBUT, Sx, ST-I, or TMH in either the dry eye group or the non-dry eye group at any postoperative time point. Regarding incision shape, there was no difference in tBUT, Sx, ST-I or TMH at any postoperative time point in the dry eye group. In the superior incision sub-group of the non-dry eye group, tBUT and Sx were worse in the grooved incision group at day 1. In the temporal incision sub-group of the non-dry eye group, Sx were worse in the grooved incision group at 1 day, 3 days, and 10 days postoperatively. In both groups, significant correlations were noted between microscopic light exposure time and dry eye test values, but no correlation was noted between phacoemulsification energy and dry eye test values. ConclusionsCataract surgery may lead to dry eye. A grooved incision can aggravate the symptoms during the early postoperative period in patients without dry eye preoperatively. Long microscopic light exposure times can have an adverse effect on dry eye test values. 相似文献

AIM: To investigate the efficacy of combined topical 0.05% cyclosporine A (CsA; Restasis®, Allergan pharmaceuticals, USA) and 0.1% sodium hyaluronate treatment in dry eyes with meibomian gland dysfunction (MGD).
METHODS: In a retrospective analysis, 53 patients (106 eyes) with MGD were enrolled and performed lid warm massage for 10min daily and be instilled preservative free sodium hyaluronate 0.1% eye drops 4 times daily. Patients were divided into subjects treated with topical 0.05% CsA and preservative free sodium hyaluronate vehicle (experimental group, n=74 eyes) and subjects treated with the preservative free sodium hyaluronate vehicle (control group, n=32 eyes). They were evaluated at baseline and 1, 2, and 3mo for subjective symptoms and objective signs including tear film break-up time (tBUT), Schirmer test, corneal staining (CS) score, lid margin telangiectasia (LMT), meibomian gland secretion (MGS), and conjunctival injection (CI).
RESULTS: In the short-term treatment, the experimental group showed a statistically significant improvement in the ocular surface disease index (OSDI; P<0.001), tBUT (P=0.004), Schirmer test score (P=0.008) and LMT (P=0.021) by repeated measure ANOVA. Additionally, mean changes from baseline in OSDI (P<0.001), tBUT (P=0.001), Schirmer test score (P=0.029), CS score (P=0.047), LMT (P=0.002), CI (P=0.030) were improved better in the experimental group than in the control group at 3mo. However, there was no significant difference between the two groups in MGS (P=0.67).
CONCLUSION: In dry eyes with MGD, 0.05% CsA improves the tear film stability as well as subjective ocular discomfort, and is effective in controlling lid margin inflammation. 相似文献

PurposeColombia is a country with a high prevalence of hypothyroidism, approximately 18.5% compared to the rest of Latin American countries, which is estimated at 10%. That is why in the ophthalmology consultation we find a large proportion of patients with this disease and who also present symptoms of dry eye. When conducting a search in the medical literature, most publications refer to the clinical presentation of dry eye in hyperthyroidism, which is why the main objective of this study is to evaluate tear function tests in the diagnosis of dry eye in patients with hypothyroidism. MethodsThis is an observational, cross-sectional study carried out in the period between May and December 2019 in the ocular surface unit of the Ophthalmic Technology Center (CTO) in Bogotá. The tests of: OSDI test (Ocular Surface Disease Index), Schirmer type I, tear meniscus height, NiBUT, Osmolarity, Ferning test, Lisamine Green test of 59 patients with Dry Eye Disease and history of hypothyroidism. ResultsSchirmer type I and NiBUT tests were the parameters that presented the highest percentage of severity, while lissamine green staining and meniscometry showed a tendency to normality. ConclusionsThe population of this study presents a mixed type dry eye without epithelial cell damage. 相似文献

ObjectiveTo analyze the relationship between dry eye symptoms and modern dry eye tests, including the Schirmer I test, lipid layer thickness (LLT), and blinking pattern by LipiView interferometer. DesignCross-sectional study. Participants115 dry eye outpatients. MethodsDry eye symptoms were quantified by questionnaire scores, such as Ocular Surface Disease Index (OSDI) and Standard Patient Evaluation of Eye Dryness (SPEED). LLT, complete, and incomplete blinking rate were recorded by the LipiView interferometer. Results115 patients (229 eyes, mean age = 60.5 ± 13.6 years) were enrolled in this study. The mean value of the SPEED and OSDI scores was 9.5 and 10.2, respectively. A total of 44.3% of all subjects had severe dry eye syndrome (SPEED, OSDI ≥ 10). LLT (mean = 71.2 nm) was inversely correlated with both the SPEED and OSDI ( p = 0.003 and 0.004, respectively). The incomplete-to-complete ratio of blinking rate (i/c ratio) was correlated with both the SPEED and OSDI ( p = 0.0048 and 0.0234, respectively). Patients with LLT less than 69 nm were more likely to have severe dry eye syndrome. There was no significant relationship between the Schirmer I test and the SPEED or OSDI. However, LLT was inversely related to the Schirmer I test (linear regression, p = 0.0002, r = ?0.1857). ConclusionsLLT and the i/c ratio were significantly correlated to dry eye symptoms. Eyes with thinner LLT are more likely to have better aqueous tear production. The role of the reciprocal influence between each tear component in the maintenance of tear function warrants further investigation. 相似文献

Purpose:The aim of this study was to describe the clinical characteristics and risk factors of short tear film break-up time (TBUT) type of dry eye disease and compare it with other types of dry eye diseases. Methods:This cross-sectional study included 570 patients (≥ 20 years) from the outpatient department using systematic random sampling. Results:The age-adjusted prevalence of short TBUT type of dry eye disease was 5.4% (95% confidence interval: 3.2–6.8%). There was no difference ( P > 0.05) between the total and subscale scores of the Ocular Surface Disease Index ® questionnaire between patients with short TBUT and those with aqueous tear deficiency. Both these groups differed significantly ( P < 0.05) in the findings of TBUT, Schirmer I test, and Lissamine green staining score. The common symptoms in patients with short TBUT type of dry eye disease were eye fatigue (25.4%), heaviness in the eye (19.7%), and an uncomfortable sensation (14.1%). The symptoms in the aqueous tear deficiency group were light sensitivity (28.2%), dryness (19.2%), burning (13.0%), foreign body sensation (12.8%), and blurring of vision (14.1%). The risk factors associated with short TBUT type of dry eye disease were the presence of meibomian gland dysfunction (odds ratio: 3.759 [95% confidence interval: 2.135–6.618], P < 0.0001) and female sex [odds ratio: 1.954 (95% confidence interval: 1.042–3.667), P = 0.037]. Conclusion:Patients with short TBUT type of dry eye disease have symptom severity similar to aqueous tear-deficient dry eyes, but the pattern is different. The finding of this type of dry eye disease in India indicates its global presence, and ophthalmologists should consider it in their differential diagnoses. 相似文献

AIM: To determine the role of subjective assessment using McMonnies dry eye questionnaire in diagnosing dry eye disease and its association with clinical tests.
METHODS: There were 500 patients screened for dry eye using McMonnies dry eye questionnaire between May to October 2013 at the outpatient Department of Ophthalmology of a medical college hospital. All 500 patients were subjected to clinical tests. Dry eye was defined as having one or more symptoms often or all the time. Positive signs were if one or both eyes revealed tear film breakup time (TBUT) of ≤10s, a Schirmer test score of ≤10 mm, a Rose Bengal staining score of ≥1, a Lissamine green staining score of ≥1 or existence of meibomian gland disease (≥grade 1). Statistical analysis was performed to describe the distribution of symptoms and signs, to assess the correlations between McMonnies score (MS) and variable clinical signs of dry eye, and to explore the association between dry eye symptoms and variable clinical signs. Analysis was performed using software package Epi info. A Probability (P) value using Chi-square test of <0.005 was taken as significant.
RESULTS: Dry eye prevalence with symptoms (questionnaire), Schirmer test, TBUT, Rose Bengal staining and Lissamine green staining was 25.6%, 15.20%, 20.80%, 23.60%, and 22.60% respectively. Among those with severe symptoms (MS>20), 75.86% had a low TBUT (<10s), 58.62% had a low Schirmer’s I test (≤10 mm), 86.20% had Rose Bengal staining score of ≥1, 79.31% had Lissamine green staining score of ≥1. We found statistically significant associations between positive Schirmer test and arthritis (P<0.002), dryness elsewhere (P<0.001), contact lens use (P<0.002), systemic medication (P<0.0001), sleeping with eyes partly open (P<0.002), history of dry eyes treatment (P<0.0001), environmental factors (P<0.001), swimming (P<0.001).
CONCLUSION: Subjective assessment plays an important role in diagnosing dry eye disease. There is strong correlation between MS and Schirmer test, TBUT, Rose Bengal staining and Lissamine green staining in normal as well as marginal and pathological dry eye. 相似文献

Purpose:To evaluate and compare the efficacy of autologous platelet-rich plasma (aPRP) eye drop and artificial tear (AT) eye drop in moderate to severe symptomatic dry eye disease (DED). Methods:This prospective interventional study included 121 eyes of 61 patients of moderate to severe DED. Patients were divided into aPRP (31 patients) and AT (30 patients) group. Ocular Surface Disease Index (OSDI) score, tear film breakup time (TBUT) (s), corneal fluorescein staining (CFS) score, and Schirmer test score (mm) of both the groups were evaluated and compared pre-treatment and post-treatment at the end of 3 months. Results:The mean age of the aPRP group and AT group was 52.8 ± 12.8 years and 55.5 ± 13.4 years, respectively. At the end of 3 months, OSDI score reduced more in the aPRP group as compared to AT group, and the mean difference (−22.7) was statistically significant ( P < 0.001). There was no significant difference in post-treatment Schirmer test score between the two groups ( P = 0.44). Post-treatment improvement in TBUT and CFS score in the aPRP group was significantly higher in the aPRP group as compared to that in the AT group ( P < 0.05). Bruising at the site of blood withdrawal was noted in two patients in the aPRP group. Conclusion:aPRP is safe and more effective than AT in treating patients with moderate to severe symptomatic DED. 相似文献

PurposeTo evaluate the effect of the intense pulsed light (IPL) and meibomian gland (MG) expression (MGX) combination therapy according to the total numbers of sessions in the meibomian gland dysfunction (MGD). MethodsNinety patients with MGD were included. Patients had maximal five sessions of IPL (Aqua Cel, Jeisys Medical) and MGX combination therapy at 2-week intervals. The ocular surface disease index (OSDI) questionnaire score, MG profile grades, tear matrix metalloproteinase-9 (MMP-9), tear break-up time (BUT), tear osmolarity, tear secretion, and corneal erosions were evaluated. ResultsThe number of patients who had a total of one to five sessions (1S to 5S) was 10, 25, 17, 20, and 18, respectively. The time-serial decrease of OSDI scores was significant in patients who had three or more sessions (3S, p = 0.002; 4S, p < 0.001; 5S, p < 0.001). The MG expressibility grade decreased with two or more sessions (2S–5S, p < 0.001), but the meibum quality significantly improved with all sessions (1S, p = 0.012; 2S, p = 0.024; 3S, p = 0.015; 4S, p < 0.001; 5S, p < 0.001). Although tear BUT increased even in patients with one session (1S, p = 0.040; 3S, p = 0.005; 4S, p = 0.006; 5S, p = 0.021), tear MMP-9, osmolarity, Schirmer I, and corneal erosions were not improved in every number of sessions. The female sex was the sole contributor to the final symptomatic improvement ( p = 0.042), and the MGD stages were not related to the final OSDI decrease. ConclusionsThe OSDI score, MGD grades, and BUT were improved after the IPL and MGX combination therapy in MGD patients. Unlike MGD grades and tear film instability might be improved just after a few sessions, the overall subjective relief was accomplished in three or more sessions. 相似文献

Purpose:A study of the association between vitamin D deficiency and dry eye syndrome (DES) in the Indian population. Methods:This was a cross-sectional, hospital-based observational study. Sixty patients diagnosed with vitamin D deficiency (<20 ng/dl) who met the inclusion criteria were sent to the Eye OPD from the Endocrinology OPD (case) were compared to 60 subjects with normal vitamin D levels (≥20 ng/dl) who attended the Eye OPD (controls). The examination of the tear film was done using Whatman filter paper in Schirmer test I and Schirmer test I (with anesthesia). The tear film break-up time (TFBUT) was determined by slit-lamp examination using the fluorescein stain, and scoring using the ocular surface disease index (OSDI) was done. Results:A significant difference in the mean values of Schirmer I and Schirmer I test (with anesthesia) ( P < 0.001) was seen between the case and control groups. A significant difference in the mean values of TFBUT ( P < 0.001) and OSDI scores ( P < 0.01) was also seen between the two groups. Conclusion:A positive association was found between vitamin D deficiency and dry eye on comparing the above parameters. 相似文献

Background To compare the symptom scores of children with those of adults with the same degree of mild ocular surface signs. Methods This study included patients with at least one ocular surface symptom and sign. Data obtained from 45 subjects aged 8.79?±?2.95 yr (Mean ± SD) (pediatric group) and 45 adults aged 52.87?±?10.87 yr (adult group) who were matched to each pediatric patient based on ocular surface signs were analyzed. Demographic data including age and sex; parameters of ocular surface signs including fluorescein staining score, tear film breakup time and Schirmer test score; symptom scores including ocular surface disease index (OSDI) and visual analog scale (VAS) were assessed and compared between the two groups. Results Significant differences emerged in sex ratio as well as in age between the two groups ( P?<?0.001, for both). Regarding ocular surface signs and tear film tests, the study revealed no significant differences in fluorescein staining score (1.44?±?1.95 vs. 1.40?±?1.68 P?=?0.913), tear film break up time (4.96?±?1.94 vs. 3.82?±?1.85 s, P?=?0.612) and Schirmer score (12.79?±?9.05 vs. 10.11?±?8.45 mm / 5 min, P?=?0.370). Regarding dry eye symptoms, both OSDI and VAS were significantly lower in the pediatric group ( P?=?0.001 and?<?0.001, respectively) than in the adult group. Conclusion Pediatric patients with mild ocular surface damage may report fewer dry eye symptoms compared to adult patients with similar stages of ocular surface damage. 相似文献

ObjectiveBecause of high variability, tear film osmolarity measures have been questioned in dry eye assessment. Understanding the origin of such variability would aid data interpretation. This study aims to evaluate osmolarity variability in a clinical setting. Material and methodsTwenty dry eyes and 20 control patients were evaluated. Three consecutive osmolarity measurements per eye at 5 min intervals were obtained. Variability was represented by the difference between both extreme readings per eye. Machine learning techniques were used to quantify discrimination capacity of tear osmolarity for dry eye. ResultsMean osmolarities in the control and dry eye groups were 295.1 ± 7.3 mOsm/L and 300.6 ± 11.2 mOsm/L, respectively ( P = .004). Osmolarity variabilities were 7.5 ± 3.6 mOsm/L and 16.7 ± 11.9 mOsm/L, for the control and dry eye groups, respectively ( P < .001). Based on osmolarity, a logistic classifier showed an 85% classification accuracy. ConclusionsIn the clinical setting, both mean osmolarity and osmolarity variability in the dry eye group were significantly higher than in the control group. Machine learning techniques showed good classification accuracy. It is concluded that higher variability of tear osmolarity is a dry eye feature. 相似文献

ObjectivesTo assess the effects on dry eye symptoms and tear dynamics of switching from a prostaglandin with a preservative to a preservative-free prostaglandin. Material and methodsFourteen patients (N = 28 eyes) with open-angle glaucoma and dry eye symptons, treated with preserved latanoprost, travoprost or bimatoprost were included in this uncontrolled prospective study. Ocular symptoms were analysed using a validated ocular surface disease questionnaire and ocular signs were assessed with tear clearance, Schirmer and tear function index test (TFI = Schirmer/clearance). Patients were assigned to preservative-free tafluprost treatment, and measurements were repeated 4 weeks after change of medication. Wilcoxon test and Spearman correlation coefficient were used in the statistical analysis. ResultsNo statistically significant difference in intraocular pressure (IOP) was observed after switching to tafluprost. Mean IOP at baseline was 20.4 mmHg (SD 2.2) and after 4 weeks 19.9 mmHg (SD 2.6), ( P>.05). The mean questionnaire score significantly decreased from 9.7 (SD 3.7) at baseline to 5.4 (SD 2.7) after one month ( P<.001). No significant differences in tear clearance, Schirmer or TFI were found ( P>.05). At baseline, tear clearance = 0.13 (SD 0.07), Schirmer = 10.7 mm (SD 6) and TFI = 80 (48-156). After 4 weeks, tear clearance = 0.1(SD 0.07), Schirmer = 9.5 mm (3.9) and TFI = 104 (48-216). A significant association between questionnaire score and tear clearance after 4 weeks was observed (Spearman coefficient = 0.62; P=.014). ConclusionsSwitching from preservative prostaglandin with a preservative to preservative-free tafluprost treatment improves dry eye symptoms and suggests an improvement in TFI. 相似文献

AIM: To investigate the effects of sulforaphane (SFN) on transforming growth factor (TGF)-β2 stimulated migration and epithelial-mesenchymal transition (EMT) in ARPE-19 cells. METHODS: ARPE-19 cells were cultured in the presence or absence of SFN or TGF-β2. SFN toxicity was assessed by performing a lactate dehydrogenase assay (LDH) and 3-(4,5-Dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assays, and cell migration was evaluated by Transwell migration assay. Actin stress fiber formation in ARPE-19 cells was determined using immunofluorescence analysis. Immunoblotting analysis was used to determine fibronectin and α-smooth muscle actin expressions along with the degree of Smad and Akt phosphorylation. RESULTS: SFN inhibited ARPE-19 migration. Additionally, SFN attenuated TGF-β2-induced appearance of actin stress fibers as well as fibronectin and α-smooth muscle actin expressions in these cells. SFN also hindered the TGF-β2-stimulated phosphorylation of Smad2, Smad3, and Akt. SFN showed no cytotoxicity towards ARPE-19 cells. CONCLUSION: SFN inhibite TGF-β2-stimulated migration and EMT in ARPE-19 cells, probably by preventing the establishment of actin stress fibers and Akt and Smad2/3 signaling. 相似文献

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

Purpose: To evaluate the presence of dry eye and primary Sjögren syndrome (SS) in patients with migraine. Methods: In total, 46 eyes of 46 patients with migraine (group 1) and 50 eyes of 50 healthy subjects (group 2) were included in this study. Detailed ophthalmologic, neurologic and rheumatologic examination were performed on all participants. Ocular surface disease index questionnaire, tear function tests, visual analog scale for pain, serologic analysis were also performed. Results: Dry eye symptoms and findings were significantly higher and more severe in group 1 when compared with group 2. Primary SS was not found in any of the participants. The migraine lifetime duration was negatively correlated with the tear function tests while it was positively correlated with the ocular surface disease index scores. Conclusions: Dry eye symptoms and findings are higher in migraine patients when compared with the healthy subjects without the presence of Sjögren syndrome. 相似文献

Background One of the most frequent ocular features of systemic sclerosis (SSc) is dry eye disease (DED), which has been identified to occur in 37–79% of patients. Although several studies have found weak or no correlations between symptoms and signs of dry eye, symptoms are often the motivation for seeking eye care, and are therefore a critical outcome measure when assessing treatment effect. The aim of this study is to evaluate the impact of symptoms of dry eye on vision-related quality of life in patients with systemic sclerosis, and to investigate the relation between clinical tests and symptoms of dry eye in these patients. Methods In this cross-sectional study, 45 consecutive patients with SSc were enrolled. For evaluation of the symptoms the “Ocular Surface Disease Index (OSDI)” questionnaire was applied to all patients. After that, all individuals were submitted to a full ophthalmic examination, including the following tests: tear break-up time, Schirmer I, rose bengal staining. Patients were then grouped into dry eye and non-dry eye groups with regard to the diagnosis of dry eye. Mann–Whitney test was used to compare continuous variables, whereas the Fisher exact test was used to compare categorical data between groups. Spearman’s correlation test was used to analyze the correlations between clinical tests and OSDI scores. P values?<0.05 were considered significant. Results Dry eye disease was diagnosed in 22 patients (48.9%). Other ocular surface abnormalities found were: blepharitis (40% of the patients), pterygium (15.6%), pinguecula (82.2%), and superficial punctate keratitis (26.7%). Among the 45 patients, 29 patients (64.4%) had symptoms of ocular surface disease. The mean OSDI score was 26.8?±?25.8 (SD). There were no statistically significant differences in OSDI scores between DED and non-DED patients. No substantive correlations were found between OSDI scores and TBUT, Schirmer I, or rose bengal staining score, and none of the observed correlations reached statistical significance. Conclusion Symptoms of dry eye have a moderate impact on vision-related quality of life in patients with systemic sclerosis and do not correlate well with clinical findings. 相似文献

PurposeTo investigate sex and age differences in symptoms and signs in a Norwegian clinic-based cohort of patients with dry eye disease (DED). MethodsVisitors at the Norwegian Dry Eye Clinic were examined using Ocular Surface Disease Index (OSDI) questionnaire score, tear osmolarity, tear break-up time (TFBUT), ocular surface staining, corneal sensitivity, Schirmer I test, and meibum expressibility (ME) and quality (MQ). A diagnosis of DED was made by an ophthalmologist based on symptoms and signs, and only DED patients were enrolled in the study: 1823 patients (338 males; mean age 51.2 ± 16.2 years; 1485 females; mean age 52.5 ± 16.0 years). The patients were divided into age subgroups: 20–39 years, 40–59 years and ≥60 years. Sex differences in the aforementioned tests were analyzed. Values were reported as mean ± standard deviation (SD), and intergroup comparisons were performed using Mann-Whitney U test. Multiple regression was used to analyze sex and age influences on symptoms and signs. ResultsWhen patients of all ages were analyzed, females had increased osmolarity, shorter TFBUT, reduced MQ and ME and higher corneal sensitivity. OSDI, Schirmer I test, ocular surface staining and corneal staining were not significantly different between the sexes. Only with TFBUT and ME were the sex difference present in all age subgroups. Multiple regression showed that all parameters were influenced by either sex or age, but only TFBUT and ME were influenced by both sex and age. (all p < 0.05). ConclusionsSex and age differences in dry eye were most consistent in TFBUT and ME, that indicate differences in meibomian gland functionality. Sex and age subgroup stratification is important in future studies investigating DED in other populations. 相似文献

ObjectivesThis study was performed to investigate whether different grades of diabetic retinopathy correlate with tear and ocular surface function in diabetic patients without subjective symptoms of dry eye. MethodsA total of 129 eyes of 72 patients without dry eye, assessed using McMonnies questionnaire were recruited to the study. The tear film and ocular surface were evaluated using the Schirmer test, tear film break-up time (BUT), fluorescein and lissamine green staining test, and conjunctival impression cytology. The results were analysed. ResultsA normal Schirmer test and BUT was obtained in 51 and 67% of the eyes of diabetics patients, respectively. Fluorescein and lissamine green staining were negative in 81 and 95% of the eyes. The area and density of goblet cells was 580.46 ± 370 μm 2 and 235.58 ± 109.03 goblets cell/mm 2, respectively. ConclusionsDiabetic retinopathy patients without subjective symptoms of dry eye and normal Schirmer and BUT test showed pathological grades of squamous metaplasia. 相似文献
