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.
