AIM: To investigate the short-term efficacy of intense pulsed light(IPL)for the comprehensive treatment of blepharokeratoconjunctivitis(BKC).

METHODS: A total of 66 patients(66 eyes)diagnosed with BKC in Cangzhou Aier Eye Hospital from December 2020 to December 2021 were selected(All selected the more severe eye for research). They were divided into two groups according to the different clinical treatment, with 30 cases(30 eyes)in control group and 36 cases(36 eyes)in treatment group. Both groups were administrated for 1wk(0.1% fluorometholone eye drops, 0.3% sodium hyaluronate eye drops and tobramycin dexamethasone eye ointment). Ocular surface state was taken as the baseline level. The control group continued to receive drugs(0.1% fluorometholone eye drops and 0.3% sodium hyaluronate eye drops), while the treatment group is required to undergo regular IPL in the hospital on the basis of drug treatment(atomization fumigation+IPL+meibomian gland massage + meibomian margin cleaning+cold compress), once every 2wk, for a total of 4 times. The patients in both groups were followed up at 1wk after drug treatment, before the first IPL treatment(V1), before the third treatment(V2)of IPL, and at 2wk after the fourth treatment(V3)of IPL, respectively. Data including ocular surface disease index(OSDI), the morphology of meibomian margin under the slit lamp, the nature of meibomian gland(MG)secretion, the difficulty of excretion of MG secretion, non-invasive tear film break-up time(NIBUT), red eye index and corneal fluorescent staining were collected. Moreover, the best corrected visual acuity(BCVA), intraocular pressure, anterior segment and fundus were examined to observe the occurrence of complications.

RESULTS: There was no statistically significant difference in the indexes of the patients in both groups before treatment, including OSDI, morphology of meibomian margin, nature of MG secretion, the difficulty of excretion of MG secretion, NIBUT, ocular surface hyperemia and corneal fluorescein sodium staining(P>0.05). In V2 and V3, the indexes of the patients in both groups, including OSDI, morphology of meibomian margin, nature of MG secretion, the difficulty of excretion of MG secretion, ocular surface hyperemia and corneal fluorescein sodium staining, were lower than those before treatment(V1), while the NIBUT was longer than that before treatment, the differences were statistically significant(all P<0.05). There was difference between the groups(P<0.05). Those indexes improved more obvious in the treatment group. No obvious complications occurred in all patients.

CONCLUSION: IPL comprehensive treatment have better effect on reducing the inflammation of ocular surface, and improving the function of MG, and it can be used as a new option for physical therapy of BKC.
