Objectives: To investigate the changes of dry eye-related clinical manifestations, ocular surface parameters, and tear inflammatory cytokines after upper blepharoplasty.Methods: Forty eyes of 20 who underwent upper blepharoplasty were divided into either the group with or the group without preexisting dry eye before upper blepharoplasty. Ocular Surface Disease Index (OSDI), Schirmer I test, tear meniscus height, lipid layer thickness, non-invasive tear break-up time (NIKBUT), fluorescein tear film break-up time (FBUT), corneal fluorescein staining, meibum expression, lid margin changes, and tear inflammatory cytokines were assessed preoperatively and at 1, 3, and 6 months postoperatively. Correlations between inflammatory cytokines and dry eye-related parameters were determined.Results: The OSDI scores increased significantly at 1 month (p = 0.040) and subsequently decreased to the preoperative levels at 6 months postoperatively in subjects with dry eye. First (f)-NIKBUT and FBUT were significantly shortened at 1, 3, and 6 months postoperatively in subjects with dry eye (f-NIKBUT: p <0.001, p = 0.010, p = 0.042; FBUT: p = 0.002, p = 0.005, p = 0.037, respectively), but were only shortened at 1 month (p = 0.028, p = 0.005) and returned to baseline levels at 6 months postoperatively in subjects without preexisting dry eye. A significant increasing trend of interleukin (IL)-6 was found in both dry eye and subjects without preexisting dry eye (p = 0.016, p = 0.008), while IL-8 and tumor necrosis factor alpha (TNF-α) were only found to be increased in subjects with dry eye postoperatively (p = 0.031, p = 0.031). The levels of IL-8 and TNF-α were positively correlated with OSDI scores (p = 0.046, p = 0.043, respectively) and negatively correlated with f-NIKBUT and FBUT (p = 0.026, p = 0.006, respectively).Conclusions: Upper blepharoplasty might increase the release of tear inflammatory cytokines and tear film instability that contribute to the development of postoperative dry eye in the early postoperative period and the changes most relieved in 6 months. Preexisting dry eye is a higher risk factor for worse and persistent ocular surface damage after upper blepharoplasty.

This study evaluated to what extent tear film break-up time (TFBUT) could discriminate pathological scores for other clinical tests and explore the associations between them. Dry eye patients (n = 2094) were examined for ocular surface disease index (OSDI), tear film osmolarity (Osm), TFBUT, blink interval, ocular protection index (OPI), ocular surface staining (OSS), Schirmer I test, meibomian expressibility, meibomian quality, and meibomian gland dysfunction. The results were grouped into eight levels of break-up time (≤2, ≥3, ≤5, ≥6, ≤10, ≥11, ≤15, and ≥16) with or without sex stratification. Receiver-operating characteristic curve (ROC) analysis and Pearson’s correlation coefficients were used to study TFBUT’s discriminative power and the associations among the tests, respectively. Above and below each TFBUT’s cut-off, all of the parameters indicated significant difference between groups, except OSDI (cut-off 15 s) and Osm (cut-offs 5 s–15 s). At TFBUT cut-off of 2 s, sex difference could be detected for OSDI, Osm, and OSS. OPI presented the strongest discriminative power and association with TFBUT in sharp contrast to Osm, holding the poorest discriminative power with no significant correlation. The remaining parameters were within the poor to very poor categories, both with regard to discrimination and correlation. In conclusion, patients with lower TFBUT presented with more severe DED parameters at all four defined cut-off values.

Concomitant exotropia have obvious symptoms of eye discomfort in adults, and the presence of ocular surface inflammation in patients may be important mediators between concomitant exotropia and dry eye. Oculus Keratograph eye comprehensive analyzer was performed to detect noninvasive tear break time, noninvasive tear height, and eye red index, while the ocular surface disease index and schirmer I testing were made. The levels of IL-6, IL-10, IL-17A, IL-12P70, INF-γ, and TNF-α were detected in tears in patients with concomitant exotropia and healthy controls matched by age and gender through the Simoa technology. IL-6 was significantly higher in patients with concomitant exotropia ( 4.683 ± 1.329 ) pg/mL than that in normal group ( 1.455 ± 0.391 ) pg/mL, p = 0.0304 . TNF-α was also significantly higher in patients ( 0.2095 ± 0.0703 ) pg/mL than normal group ( 0.0513 ± 0.0149 ) pg/mL, p = 0.0397 . The levels of inflammatory factors in strabismic patients vs. normal controls were as follows: IL-17A (0.1551 pg/mL︰0.0793 pg/mL), IL-10 (0.3358 pg/mL︰0.0513 pg/mL), IL-12p70 (0.0253 pg/mL︰0.0099 pg/mL), and INF-γ (0.0284 pg/mL︰0.009 pg/mL) were detected, and the median of them in concomitant strabismus was 1.96-6.55-fold as much as the control group. High levels of inflammatory cytokines in tears of patients with concomitant exotropia, which may be a potentially factor promoted the occurrence of dry eye in the patients with concomitant exotropia.

To study the effects of apigenin on dry eye disease (DED) in rats. Rats were divided into six groups: (I) normal control group, (II) DED control group, (III) vehicle control group, (IV) DED + apigenin 10 mg/kg, (V) DED + apigenin 20 mg/kg, and (VI) DED + apigenin 50 mg/kg. Schirmer test, tear film break-up time (BUT), and corneal fluorescein staining were used to evaluate the effects of apigenin on the ocular surface. The related inflammatory cytokines were detected by enzyme-linked immunosorbent assay (ELISA). Histopathological examination and inflammatory index were also performed. The results showed that administration of apigenin was shown a significant effect on the recovery of ocular surface function. Compared to the control group, apigenin treatment in DED rats significantly decreased the level of the tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6); however, the interleukin-10 (IL-10) level was increased. Histopathological examination further verified the anti-inflammatory effects of apigenin on DED rats. The results demonstrated that apigenin could protect DED rats via inhibition of inflammation, suggesting that it may have potential as a therapy for DED.

Abstract Purpose: To evaluate the morphology and function of the meibomian glands (MG) in keratoconus patients.Methods: One hundred eyes of 100 keratoconus patients and 100 eyes of 100 age-matched healthy subjects were included into this study. Ocular Surface Disease Index (OSDI) scores, non-invasive break up time (NIBUT), meibography findings, fluorescein staining of the ocular surface, tear film break-up time (TBUT), and Schirmer I test were recorded in all patient eyes and were compared with controls.Results: The mean TBUT and NIBUT were significantly lower, corneal staining and OSDI scores were statistically higher in the keratoconus group (p<0.05). The mean meiboscore, partial gland, gland dropout and gland thickening scores of the upper and lower eyelids were significantly higher in keratoconus patients compared to controls (p<0.05). The NIBUT measurements significantly correlated with MG loss in both upper and lower eyelids (p<0.05). The severity of keratoconus seemed to correlate with meiboscore, partial gland, gland thickening scores in both upper and lower eyelids. Conclusion: Our data suggest that corneal ectasia in keratoconus is associated with alterations in ocular surface, tear film function and MG morphology. Early screening and treatment of MG dysfunction may improve ocular surface quality and allow better disease management in keratoconus patients.

Background/Aims: Bidens pilosa L. (Bp) is widely distributed in China and has been widely used as a traditional Chinese medicine. The aim of this study was to examine the effect of the extract of Bp on androgen deficiency dry eye and determine its possible mechanisms. Methods: Twenty-four rats were randomly divided into four groups: Group Con (control), Group Sal (physiological saline), Group Fin (oral finasteride), and Group Bp (oral finasteride and Bp). The dry eye model was established in group Fin and group Bp. Aqueous tear quantity was measured with phenol red-impregnated cotton threads with anesthesia. Tear film breakup time (BUT) and corneal epithelial damage were evaluated by fluorescein staining. Animals were sacrificed at 28 days, and ocular tissues (lacrimal gland and cornea) were evaluated with light microscopy; gene microarray analysis for inflammatory cytokines and Western blot were also performed. Results: Finasteride administration effectively induced dry eye in rats by 14 days after administration. Group Fin rats had significantly higher fluorescein staining scores and lower aqueous tear quantity and BUT than the group Con rats, and notable inflammatory cell infiltrates were observed in the lacrimal gland of group Fin rats. The fluorescein staining score, aqueous tear quantity and BUT significantly improved with Bp treatment in the group Bp rats, and the structures of the lacrimal gland were well maintained without significant lymphocyte infiltration. Cytokine antibody array data identified the cytokines B7-2/Cd86, IL-1β, IL-4, IL-6, IL-10, MMP-8, FasL, TNF-α and TIMP-1 as candidates for validation by Western blot. Expression levels of pro-inflammatory cytokines, including IL-1β, IL-6, and TNF-α, in group Fin were upregulated compared with group Con. Levels of anti-inflammatory cytokines, such as IL-4 and IL-10, in group Fin were also upregulated compared with those in group Con. Compared with group Fin, IL-1β, FasL, and TNF-α were significantly decreased in group Bp. Conclusion: The extract of Bp appears to be effective for the treatment of androgen deficiency dry eye in rats by improving aqueous tear quantity, maintaining tear film stability, and inhibiting the inflammation of the lacrimal gland.

Purpose.To evaluate the relationship between corneal and conjunctival epithelium thickness and ocular surface clinical tests in dry eye disease (DED) patients.Patients and Methods.Fifty-four patients with DED and 32 control subjects were included. Each patient underwent an ocular surface evaluation using the ocular surface disease index (OSDI), tear film break-up time (TBUT), corneal and conjunctival staining, tear film lipid layer analysis, and Schirmer test. The central corneal (CET), limbal (LET), and bulbar conjunctival epithelium thickness (BET) were acquired using spectral-domain optical coherence tomography (SD-OCT).Results.Compared to control subjects, mean BET was significantly thicker and mean LET was significantly lower in the DED group. There was no significant difference in mean CET between the two groups. The mean LET was correlated with OSDI and TBUT. The inferior LET was correlated with OSDI, Schirmer I test, TBUT, Oxford score, and corneal sensitivity. Mean BET was correlated with OSDI and TBUT, but not with Schirmer I test and Oxford score.Conclusions.In dry eye patients, a thinner limbal epithelium and a thicker bulbar conjunctival epithelium were observed. These changes were correlated to the severity of dry eye symptoms and tear film alterations.

Purpose:  To determine the role of 0.05% topical cyclosporine A (CsA) in treatment of symptomatic dry eye after LASIK (Laser-Assisted in Situ Keratomileusis). Study Design:  Interventional Case Series. Place and Duration of Study:  Ophthalmology Department, Sir Syed Hospital, Karachi, from July 2018 to Dec. 2019. Methods:  Seventy-five patients who underwent LASIK for myopic refractive error and presented with symptomatic dry eye and showed no response to artificial tears therapy after 1 month of LASIK were selected. The patient had ablation zone diameter of 6mm and flap diameter was 8.5mm to 9mm. Cyclisporine A 0.05% ophthalmic preparation was added to treatment regimen and response was observed at 1, 3 and 6 months. OSDI (Ocular Surface Disease Index) scores, Tear film break up time (TBUT), Schirmer's test (ST) values and Best Corrected Visual Acuity (BCVA) were recorded to analyze the treatment response at each visit. The statistical interpretation was done by using SPSS version 21. To interpret the correlation between pre-treatment and 6 month post treatment, Paired sample T test was applied with 95% Confidence Interval; CI and p-value of ≤ 0.05. Results:  The mean post-LASIK OSDI score of enrolled patients was 54.25 ± 10.81. After 6 months of treatment mean OSDI score was improved to 21.05 ± 5.13 (p < 0.001). Post-LASIK mean ST value was 5.2 ± 1.2 mm and mean TBUT value was 5.6 ± 1.3 seconds, which changed to 9.8 ± 1.0 mm and 8.9 ± 1.1 seconds respectively. BCVA improved from Log MAR 0.14 ± 0.09 to 0.01 ± 0.03 (p < 0.001). Conclusion:  Topical CsA 0.05% was effective in alleviating the symptoms of post-LASIK dry eye. Key Words:  LASIK, Dry eye, Ocular Surface Disease Index Score, Cyclosporine A.
