ABSTRACT
@#Surgical treatment of vitreoretinal diseases, including scleral buckling, vitrectomy, and vitreous cavity gas injection or oil injection,may lead to increased intraocular pressure after surgery. If not treated promptly, it may develop into secondary glaucoma and lead to permanent vision loss. The causes of secondary glaucoma after vitreoretinal surgery are complex and varied. Different treatment methods can be used according to the different causes of the patients. Early glaucoma is mainly treated with drugs or lasers, while patients with advanced glaucoma are treated with multiple surgeries. However, the failure rate of traditional trabeculectomy is high, and glaucoma drainage valve implantation can effectively reduce intraocular pressure. This article reviews the pathogenesis of high intraocular pressure after routine vitreoretinal surgery and the current research progress in treatment at home and abroad.
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.
