Objective To analyze the diode laser cyclophotocoagulation surgery (TDLC) in the treatment of different types in advanced glaucoma-related factors that affect the postoperative intraocular pressure; explore the use of diode laser cyclophotocoagulation surgery and more effective control in advanced glaucoma after intraocular The method of the internal pressure. The first part of the method: a retrospective clinical case studies. Advanced glaucoma cases in a total of 84 cases, 84 eye the TDLC treatment were recorded to the patient's age, gender, glaucoma categories, the number of laser spots, preoperative and postoperative IOP, preoperative and postoperative visual acuity, complications, partial correlation analysis to analyze the relevant factors affect the TDLC postoperative IOP; analysis preoperative the postoperative IOP difference and the relationship between the number of laser spots of the two-variable correlation analysis. Part II: prospective study. According to the results of the first part of the study, the proposed to give different laser points, in the case of constant laser power and duration, based on different patient preoperative IOP packet. The first group, preoperative IOP was 22-30 mmHg, surgery given laser points is 50 points; second group, preoperative IOP 31-50 mmHg surgery the given laser points 70 points; surgery before intraocular pressure of 51-70 mmHg, the surgery given laser points is 90 points. Observed in each of the cases the visual acuity, postoperative intraocular pressure, complications, and glaucoma cases with retrospective effects were observed. Follow-up the method after 1 day, 7 days, 14 days, after 30 days, 60 days, 90 days and 180 days of intraocular pressure (IOP), which period effect was observed. The results of the first part: the TDLC postoperative intraocular pressure and glaucoma type of relationship, gender, age, laser points, preoperative IOP as control variables, analysis of the relationship between the type of glaucoma and postoperative IOP. Partial correlation coefficient r = 0.2934, P = 0.023. The same way, the postoperative IOP and preoperative IOP relationship, the partial correlation coefficient r = 0.6123, P = 0.000; the postoperative IOP gender relations, the partial correlation coefficient r = -0.0092, P = 0.945; postoperative eye the relationship between the pressure and age, the partial correlation coefficient r = -0.1053, P = 0.427. The correlation analysis of preoperative the postoperative IOP difference with the laser treatment points r = 0.279; (P = 0.036). The second part: the first day after surgery a success rate of 37.04%, 26.19% increase than the success rate of the retrospective glaucoma cases, and 6 months after surgery success rate rose to 92.5% in the final. Over time, the postoperative IOP decreased, and getting closer to normal. During the observation period, no serious complications occurred, and no vision loss occurs. Conclusion 1. TDLC treatment of various types of advanced glaucoma security, efficient and quick and easy. For the Chinese people, TDLC treatment of the advanced glaucoma postoperative intraocular pressure and glaucoma type and preoperative IOP related with the patient's age, regardless of gender. Preoperative the postoperative IOP difference between the number of laser spots were positively correlated. Preoperative IOP level in the case of laser power and duration of the same, given the number of different laser spot, the method of treatment in advanced glaucoma is safe, feasible, and effective control postoperative IOP and will not increase the incidence of complications and reduce visual acuity. Over time, TDLC postoperative IOP gradually within six months and the smooth underground to the normal range.
