OBJECTIVE: To verify the efficacy of eye acupuncture combined with conventional acupuncture in the treatment of dry eye syndrome with deficiency of liver and kidney. METHODS: A total of 90 patients with dry eye syndrome with deficiency of liver and kidney were randomly divided into an eye acupuncture combination with conventional acupuncture group (eye acupuncture combination group), a conventional acupuncture group and a western medication group, 30 cases in each group. In the western medication group, sodium hyaluronate eye drops were used 3 times a day, each time 1-2 drops, 10 days as one course for 3 courses; conventional acupuncture was applied at Jingming (BL 1), Cuanzhu (BL 2), Chengqi (ST 1), Fengchi (GB 20), Hegu (LI 4), Sanyinjiao (SP 6), Zusanli (ST 36), Guangming (GB 37) in the conventional acupuncture group; on the basis of the treatment in the conventional acupuncture, eye acupuncture was added at Shangjiao, Gan (liver), Shen (kidney), Pi (spleen) in the eye acupuncture combination group. The treatment in the eye acupuncture combination group and the conventional acupuncture group were given once a day, 10 days as one course, and a total of 3 courses were needed. Subjective symptom score was performed before treatment and every 10 days during treatment. Ocular surface analyzer was used before and after treatment. RESULTS: The subjective symptom scores in the three groups were lower than those before treatment (<0.05). Compared with the conventional acupuncture group and the western medication group, the subjective symptom score after 30 d of treatment in the eye acupuncture combination group was decreased (<0.05). After treatment, the tear film break up time (BUT) was prolonged and the tear meniscus height increased in the eye acupuncture combination group and the conventional acupuncture group (<0.05). Compared with the conventional acupuncture group and the western medication group, the tear film break up time was prolonged and the tear meniscus height increased in the eye acupuncture combination group (<0.05). Corneal staining were better in all three groups than that before treatment (<0.05). The total effective rate was 93.3% (28/30) in the eye acupuncture combination group, was better than 86.7% (26/30) in the conventional acupuncture group and 73.3% (21/30) in the western medication group (<0.05). CONCLUSION Eye acupuncture combined with conventional acupuncture can significantly improve the clinical symptoms of dry eye syndrome with deficiency of liver and kidney, increase the secretion of tears, prolong the break up time of tear film, and restore the integrity of corneal epithelium.

OBJECTIVETo study the tear film function of patients with type 2 diabetes and to investigate the risk factors of dry eye in these patients.

METHODSTotally 111 patients with type 2 diabetes and 100 age- and sex-matched control subjects were studied. Tear film function was evaluated by dry eye syndrome, tear breaking up time (BUT), corneal fluorescein staining, Schirmer I test (SIt), and tear film lipid layer observation with tear scope. Dye eye score was calculated with the results of these tests.

RESULTSWhen compared with the controls, patients with type 2 diabetes showed higher dry eye score (diabetics 3.28 +/- 1.56, control 2.31 +/- 1.50, P < 0.01) and faster BUT [diabetics (6.50 +/- 4.84) s, control (12.26 +/- 7.16) s, P < 0.01], but similar SIt [diabetics (10.61 +/- 6.86) s, control (10.92 +/- 7.05) s, P > 0.05]. More diabetic patients were diagnosed as dry eye(diabetics 19.8%, control 8.0%, P < 0.05). According to their retinopathy, the diabetic patients were divided into three groups: without diabetic retinopathy (DR), with background DR, and with proliferative DR. For these three groups, the dry eye scores were 2.95 +/- 1.50, 3.38 +/- 1.48 and 4.11 +/- 1.60, respectively (P < 0.01); the SIt were (10.95 +/- 6.89) mm, (11.71 +/- 7.30) mm and (7.63 +/- 5.20) mm, respectively (P > 0.05); the BUT were (7.53 +/- 5.23) s, (5.88 +/- 4.10) s and (4.47 +/- 4.17) s (P < 0.05). Patients with DR were then devided into two groups: with photocoagulation and without photocoagulation. For these two groups, the dry eye scores were 4.71 +/- 1.14 and 3.26 +/- 1.15, respectively (P < 0.01); the BUT were (2.93 +/- 2.06) s and (6.26 +/- 4.36) s, respectively (P < 0.01); the SIt were (7.21 +/- 6.51) mm and (11.33 +/- 6.73) mm, respectively (P < 0.05); the rates of corneal fluorescein staining were 50.0% and 17.9%, respectively (P < 0.05). Dry eye score had a good correlation with diabetic retinopathy and photocoagulation (P < 0.01), but was poorly correlaed with age, gender, insulin, duration of diabetes mellitus, and metabolic control (P > 0.05).

CONCLUSIONSPatients with type 2 diabetes tend to develop tear film dysfunction. The disorders of tear film quantity and quality seem relevant to the stage of diabetic retinopathy and photocoagulation.

BACKGROUNDDry eye patients suffer from all kinds of symptoms. Sometimes, the clinical signs evaluation does not disclose any obvious difference in routine examination; in vivo confocal microscopy (IVCM) is a powerful tool for ocular surface disease. This study aimed to clarify meibomian gland (MG) alterations in dry eye patients with different symptoms and to compare the findings using IVCM.

METHODSA total of sixty patients were recruited, all subjected to Ocular Surface Disease Index (OSDI) and Salisbury Eye Evaluation Questionnaire (SEEQ), and questionnaires for the assessment of dry eye symptoms before clinical sign examinations were given to the patients. Finally, IVCM was applied to observe MG's structure. Statistical analysis was performed using the t-test, Mann-Whitney U-test and Spearman correlation analysis. The differences were statistically significant when P< 0.05.

RESULTSIn the severe symptom group, OSDI and SEEQ scores were significantly higher (P< 0.05) compared with the mild symptoms group. All other clinical sign examinations had no statistical difference in the two groups (P> 0.05). However, all the IVCM-observed data showed that patients with severe symptoms had more significant fibrosis in MG (acinar unit area 691.87 ± 182.01 μm2 for the severe, 992.17 ± 170.84 μm2 for the mild; P< 0.05) and severer decrease in the size of MG acinar units than those observed in patients with mild symptoms (MG acinar unit density [MGAUD] 70.08 ± 18.78 glands/mm2, MG acinar unit longest diameter [MGALD] 51.50 ± 15.51 μm, MG acinar unit shortest diameter [MGASD] 20.30 ± 11.85 μm for the severe, MGAUD 89.53 ± 39.88 glands/mm2, MGALD 81.57 ± 21.14 μm, MGASD 42.37 ± 14.55 μm for the mild;P< 0.05). Dry eye symptoms were negatively correlated with MG confocal microscopic parameters and positively correlated with conjunctival inflammatory cells and Langerhans cells (P< 0.05).

CONCLUSIONSIVCM application provides a strong support to differentiate dry eye patients with different symptoms: meibomian gland dysfunction (MGD) plays a pivotal role in dry eye aggravation, and using IVCM to observe MG fibrosis, changes in size and density of MG as well as status of inflammation cells can help not only correctly diagnose the type and severity of dry eye, but also possibly prognosticate in routine eye examination in the occurrence of MGD.

OBJECTIVE: To evaluate the safety and effectiveness of eyelid margin cleaning using Deep Cleaning Device for the treatment of meibomian gland dysfunction-associated dry eye. METHODS: This was a prospective, randomized, open-label, investigator-masked, and self-controlled study. We randomly assigned one eye of patients with meibomian gland dysfunction-associated dry eye to the treatment group, and the other eye to the control group. Both groups received artificial tears and lid warming; the treatment group received an additional one-time in-office eyelid margin cleaning using Deep Cleaning Device. Non-invasive tear break-up time (NITBUT) and tear meniscus height (TMH) of each eye, and Standard Patient Evaluation for Eye Dryness II (SPEED II) score of each patient were evaluated before and at one week after treatment. RESULTS: Thirty eyes of 15 patients were enrolled. No adverse effects occurred during the treatment. Compared with the baseline values, the SPEED score decreased significantly at one week after treatment (mean±95% confidence interval, 11.00±0.99 vs. 5.67±1.67, P<0.0001), the NITBUT-first in the treatment group increased significantly at one week after treatment ((4.74±1.27) s vs. (7.49±2.22) s, P=0.01). The NITBUT-first was significantly longer in the treatment group ((7.49±2.22) s) than in the control group ((5.17±0.91) s) at one week after treatment (P=0.042). No significant differences were found in other tear film parameters between the two groups. CONCLUSIONS Eyelid margin cleaning using the novel Deep Cleaning Device is a convenient, effective, and safe treatment for patients with meibomian gland dysfunction-associated dry eye.

OBJECTIVETo compare the efficacy of the patients of xerosis conjunctivitis with liver and kidney yin deficiency among the combined therapy of acupuncture and Shi's manipulation, common acupuncture and artificial tears therapy.

METHODSOne hundred and eight patients were randomized into an acupuncture group, a SHI's manipulation group and an artificial tears group, 36 cases in each group. A total of 15 cases dropped out before the end of the study, including 4 cases in the acupuncture group, 6 cases in the SHI's manipulation group, and 5 cases in the artificial tears group. In the acupuncture group, acupuncture was applied to Jingming (BL 1) and Qiuhou (EX-HN 7) on the affected side, and the bilateral Sanyinjiao (SP 6) and Taixi (KI 3). The needles were retained for 20 min. In the SHI's manipulation group, on the basis of the treatment as the acupuncture group, Shuigou (GV26) was added and stimulated with SHI's acupuncture manipulation. In these two groups, acupuncture was given 3 times a week totally for 3 weeks. In the artificial tears group, sodium hyaluronate eye drops were used, 5 times a day, for 3 weeks totally. Separately, before treatment, at the moment after the 1st treatment and 3 weeks after treatment, the subjective symptom score, Schirmer I test, breakup time (BUT) of tear film were observed in each group.

RESULTS(1) Subjective symptom score: at the moment after the 1st treatment and 3 weeks after treatment, the scores in each group were all reduced significantly as compared with those before treatment (all P < 0.05). At the moment after the 1st treatment, the score in the SHI's manipulation group and the artificial tears group was reduced apparently as compared with that in the acupuncture group (both P < 0.05). In 3 weeks of treatment, the score in the SHI's manipulation group was reduced apparently as compared with the acupuncture group and the artificial tears group (both P < 0.05). (2) For Schirmer I test, at the moment of the 1st treatment, the result in the SHI's manipulation group and the artificial tears group was improved significantly as compared with that before treatment (both P < 0.05). In 3 weeks of treatment, the result in the acupuncture group and the SHI's manipulation group group was improved significantly as compared with that before treatment (both P < 0.05). At the moment of the 1st treatment, the result in the artificial tears group was improved significantly as compared with the acupuncture group and the SHI's manipulation group (both P < 0.05). In 3 weeks of treatment, the result in the acupuncture group and the SHI's manipulation group was better than that in the artifi-cial tears group separately (both P < 0.05). (3) For BUT, the result in the acupuncture group and the SHI's manipulation group was prolonged significantly as compared with that before treatment and was prolonged apparently as compared with that in the artificial tears group (both P < 0.05) in 3 weeks of treatment.

CONCLUSIONThe intervention of SHI's acupuncture manipulation relieves the subjective symptoms of xerosis conjunctivitis of liver and kidney yin deficiency and achieves the same efficacy as the common acupuncture and artificial tears treatment. It does not present the apparent advantages as the common acupuncture in the short term for promoting the tear secretion and tears film repair.

PURPOSE: To evaluate the changes of higher order aberrations (HOAs) before and after laser subepithelial keratomileusis (LASEK) and to analyze the influence of tear film instability on HOAs of the corneal surface after LASEK. METHODS: In this cross-sectional study, 31 patients who underwent LASEK were divided into dry eye (16 patients, 32 eyes) and non-dry eye groups (15 patients, 30 eyes). Uncorrected distance visual acuity, spherical equivalent refraction, ablation depth, tear film parameters and Ocular Surface Disease Index (OSDI) questionnaire scores were evaluated in both groups. Total HOA root mean square (RMS), third-order coma, third-order trefoil and fourth-order spherical aberration (SA) of the corneal surface immediately and at 10 seconds after blinking were measured before and after surgery. RESULTS: The total HOA RMS, coma, trefoil and SA significantly increased after LASEK compared with preoperative values in both groups. In the dry eye group, total HOA RMS, coma and trefoil significantly increased except for SA at 10 seconds after blinking compared with those measured immediately after blinking. In addition, the changes of total HOA RMS, coma and trefoil were negatively correlated with tear film break-up time (R = -0.420, -0.473 and -0.439, respectively), but positively correlated with OSDI score (R = 0.433, 0.499 and 0.532, respectively). In the non-dry eye group, there were no significant differences between HOAs measured at 10 seconds after blinking and those measured immediately after blinking. CONCLUSIONS: The HOAs including coma, trefoil and SA significantly increased after LASEK. The tear film instability in the dry eye can be associated with more deterioration of the optical quality after LASEK, due to more significant increase of total HOA RMS, coma and trefoil.

Recently, the association of Th-17 cells or IL-17 with ocular inflammatory diseases such as uveitis, scleritis and dry eye syndrome was discovered. We assessed whether interleukin (IL)-17 was present in the tears of various ocular surface inflammatory diseases and the tear IL-17 concentrations were clinically correlated with various ocular surface inflammatory diseases. We measured concentrations of IL-17 in tears of normal subjects (n = 28) and patients (n = 141) with meibomian gland dysfunction (MGD), dry eye syndrome (DES), Sjogren syndrome (SS), Stevens-Johnson syndrome (SJS), graft-versus-host disease (GVHD), filamentary keratitis, and autoimmune keratitis associated with rheumatoid arthritis or systemic lupus erythematosus. Clinical epitheliopathy scores were based on the surface area of corneal and conjunctival fluorescein staining. The mean concentrations of IL-17 in tears of patients with filamentary keratitis, GVHD, autoimmune keratitis, SS, DES, MGD, SJS were significantly higher in order than that in normal subjects. Tear IL-17 concentration was significantly correlated with clinical epitheilopathy scores in the patients with systemic inflammatory disease, while tear IL-17 was not correlated with clinical severity of the cornea and conjunctiva in the dry eye patients without any systemic inflammatory disease. Tear IL-17 is likely to correlate clinically with corneal disease severity only in the patients with systemic inflammatory disease.
