ABSTRACT
AIM: To observe the therapeutic effect of the diquafosol sodium combined with intense pulsed light(IPL)on meibomian gland dysfunction(MGD)dry eye after refractive surgery.METHODS:A total of 64 patients(128 eyes)with MGD dry eye diagnosed within 6mo after laser corneal refractive surgery in our hospital from March 2021 to December 2021 were selected. They were randomly divided into control group and experimental group. A total of 33 patients(66 eyes)in the control group were treated with sodium hyaluronate combined with IPL, and 31 patients(62 eyes)in the experimental group were treated with diquafosol sodium combined with IPL. Ocular symptom scores were performed before each IPL treatment in both groups to examine non-invasive tear breakup time(NIBUT), tear meniscus height, lipid layer grade of tear film, meibomian gland deletion rate and uncorrected visual acuity.RESULTS:After IPL treatment, ocular symptom scores and meibomian gland deletion rate score of two groups were decreased continuously. NIBUT, tear meniscus height and lipid layer grade of tear film were increased continuously, and there was no significant change in uncorrected visual acuity. NIBUT of patients in the experimental group was better than that in the control group before the third IPL treatment(6.24±0.27s vs. 5.51±0.24s, P=0.046).CONCLUSIONS:Both diquafosol sodium and sodium hyaluronate combined with IPL showed good therapeutic effect on MGD dry eye, but there was no significant difference in the short-term efficacy between the two groups.
ABSTRACT
AIM: To evaluate the clinical efficacy of P2Y2 agonist diquafosol sodium(DQS)eye drops in the treatment of diabetic dry eye.METHODS: A total of 80 patients(160 eyes)with diabetic dry eye who admitted to our hospital from January 2022 to March 2022 were selected. They were randomly divided into study group and control group. A total of 40 patients(80 eyes)in the study group were treated with 3% DQS eye drops and 40 patients(80 eyes)in the control group were treated with 0.3% sodium hyaluronate eye drops. The ocular surface disease index(OSDI)score, non-invasive tear meniscus height(NITMH), first non-invasive tear film break-up time(NIBUTf), average non-invasive tear film break-up time(NIBUTav), tarsal gland loss score, lipid layer thickness grade and bulbar redness analysis(including conjunctival grade and ciliary grade), were examined before treatment and at 1wk, 1 and 3mo after treatment, respectively. Furthermore, corneal fluorescence staining and conjunctival lissamine green staining were analyzed based on the ocular surface staining score(OSS), and the conjunctival impression cytology and confocal microscopy were evaluated before and 3mo after treatment, respectively.RESULTS: There were no differences in OSDI score, tarsal gland loss score, conjunctival grade score and ciliary grade score between the two groups before and after treatment(P>0.05). OSS scores in the study group were lower than those in the control group, while NITMH, NIBUTf and NIBUTav were higher than those in the control group at 1 and 3mo after treatment(P<0.05). After 3mo of treatment, the density of conjunctival goblet cells increased and corneal dendritic cells decreased in the study group compared with the baseline(all P<0.05), while there were no significant changes in the control group compared with the baseline(all P>0.05).CONCLUSION: 3% DQS eye drops were effective in treating diabetic dry eye without serious complications.
ABSTRACT
AIM:To investigate the effect of 3% diquafosol sodium eye drops combined with intense pulsed light on the treatment of meibomian gland dysfunction and the change of meibomian glands.METHODS: Prospective study. A total of 141 patients(282 eyes)who were diagnosed with meibomian gland dysfunction from January 2021 to May 2022 in our hospital were selected and they were randomly divided into the control group(73 cases, 146 eyes)and the observation group(68 cases, 136 eyes)according to random number table. The control group was given 0.3% sodium hyaluronate eye drops combined with intense pulsed light, and the observation group was treated with 3% diquafosol sodium eye drops combined with intense pulsed light. The subjective symptom score, physical sign score, non-invasive tear break-up time, tear meniscus height, lipid layer thickness, and meibomian gland density before and after the treatment were compared between the two groups at 2wk after the end of treatment.RESULTS: There were no differences in the subjective symptom score, physical sign score, non-invasive tear break-up time, tear meniscus height, lipid layer thickness, and meibomian gland density between the two groups of patients before treatment(P>0.05). After 2wk of treatment, the symptom scores and physical sign scores of patients in the two groups continued to decrease, non-invasive tear break-up time and lipid layer thickness continued to increase, and the meibomian gland density also increased. The tear meniscus height in the observation group increased, while the control group showed no significant changes. The observation group had better clinical indicators than the control group(P<0.05). No obvious complications were observed in all patients.CONCLUSION: The combination of diquafosol sodium eye drops and intense pulsed light is synergistic in the treatment of meibomian gland dysfunction, with significant therapeutic effects and improvement of meibomian gland repair, which is significantly superior to simple intense pulsed light therapy.
ABSTRACT
AIM:To explore the efficacy of intense pulsed light combined with meibomian gland massage and diquafosol eye drops in lipid deficiency dry eye disease and related cytokines.METHODS: A total of 511 patients(1 022 eyes)with lipid deficiency dry eye diagnosed in the ophthalmology clinic of our hospital from January to December 2021 were selected as the research objects. They were divided into two groups according to the patient's wishes: 294 cases(588 eyes)in the study group were treated with diquafosol sodium eye drops combined with intense pulsed light and meibomian gland massage, while 217 cases(434 eyes)in the control group were treated with artificial tears combined with intense pulsed light and meibomian gland massage. The levels of tear tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β)and lactoferrin(LF)before and after treatment were detected, the corneal fluorescein staining(CFS)score, tear film break-up time(BUT), and Schirmer Ⅰ(SⅠt)under no surface anesthesia, ocular surface disease index(OSDI)were compared, the correlation between TNF-α, IL-1β, LF levels and CFS, BUT, SⅠt, OSDI before treatment was analyzed, and the occurrence of adverse reactions was observed.RESULTS: There was no significant difference in preoperative OSDI, SⅠt, BUT, CFS and levels of TNF-α, IL-1β and LF between the two groups(P>0.05). The SⅠt, BUT, CFS and levels of TNF-α, IL-1β and LF in the study group at 3, 6 and 9wk after treatment were better than those of control group(P<0.05). There were no differences in OSDI score of both groups at 9wk after treatment(P>0.05). The TNF-α and IL-1β were negatively correlated with SⅠt and BUT, while they were positively correlated with CFS and OSDI; LF and SⅠt were positively correlated with SⅠt and BUT, while they were negatively correlated with CFS and OSDI(all P<0.01); The adverse reaction rate of the study group(5.78%)was significantly lower than that of the control group(11.52%; P<0.05).CONCLUSION: Intense pulsed light combined with meibomian gland massage and diquafosol sodium eye drops is effective and well tolerated in the treatment of lipid deficiency dry eye.
ABSTRACT
AIM: To observe the clinical effect of 3% diquafosol sodium eye drops in treatment of meibomian gland dysfunction-related dry eye.METHODS: The study involved 280 patients totally with meibomian gland dysfunction-related dry eye in the ophthalmology department, Hangzhou Hospital of Traditional Chinese Medicine from May 2020 to May 2021. Patients were divided into the treatment group(160 cases with 320 eyes)and the control group(120 cases with 240 eyes)according to the randomized number table method. The control group was treated with YangXueRunMu formula combined with 0.3% sodium hyaluronate eye drops, the treatment group was treated with YangXueRunMu formula combined with 3% diquafosol sodium eye drops. Both groups were administered for 4wk. The following indicators were measured before and after treatment at 2 and 4wk, respectively: the ocular surface disease index(OSDI)score, Schirmer I test( SⅠt), comprehensive analysis of tear meniscus height(TMH), non-invasive tear film break-up time(NITBUT), meibomian gland lipid secretion of smooth degree scoring and meibomian gland loss rate score, the determination of interleukin-6(IL-6)in tears and the level of tumor necrosis factor-alpha(TNF-α). The efficacy of these tests results was evaluated among these indicators.RESULTS: The overall effective rates of the treatment group and the control group were 95.6% and 81.7% respectively(P<0.05). After 2, 4wk of treatment, the ocular surface disease index(OSDI), NITBUT, meibomian gland lipid secretion scoring, meibomian gland loss rate score and the levels of IL-6 and TNF-α in tears of two groups were significantly different than before treatment(P<0.05). and the treatment group was better than the control group; there was no difference between the SⅠt and TMH groups before and after treatment in the two groups(P>0.05).CONCLUSION: The 3% diquafosol sodium eye drops can promote the normal secretion of meibomian gland by prolonging the homeostasis of the tear membrane, and it can also inhibit the release of inflammatory factors in tears in the treatment of blebomian gland dysfunction-related dry eye.
