ABSTRACT
To compare the adjuvant therapeutic effect of silicone oil and ointment applied to the lacrimal laser angioplasty.METHODS: Totally, 134 eyes of 102 cases who were diagnosed as lacrimal duct obstruction ( except chronic dacryocystitis) were divided into two groups. Sixty eyes were performed laser plastic operation and silicone oil filling. Seventy - four eyes were adopted laser plastic operation with cloth enzyme dexamethasone eye ointment filling. All patients were followed up for 3 ~ 15mo. The clinical effect and the number of irrigation of two groups were compared 3mo after treatment, and to assess the merits of the method.RESULTS: The efficiency of the silicone oil group was 87% and that of the eye ointment group was 84%. There was no statistically significant difference (P>0. 05). The number of lacrimal duct flushing of the silicone oil group was 7. 20±1. 22 times among postoperative 3mo, and that of the eye ointment group was 7. 96 ± 1. 79 times. The number of lacrimal duct exploration through of the silicone oil group was 0. 62 ± 0. 87 times, that of the eye ointment group was 1. 43 ± 1. 48 times. There was statistically significant differences compared between the two groups (both P<0. 05).CONCLUSlON:The effect of laser plastic operation and silicone oil filling treating obstructive diseases of lacrimal duct is similar to laser plastic operation with cloth enzyme dexamethasone eye ointment, but the postoperative care of the former is more simple. Patients can significantly reduce the frequency of lacrimal duct flushing and lacrimal duct exploration through.
