ABSTRACT
AIM:To observe the effect of phacoemulsification and intraocular lens ( IOL ) implantation combined with goniosynechialysis on corneal endothelial cells for the treatment of primary angle closure glaucoma ( PACG ) combined cataract, and to analyze the relative factors.METHODS: Ninety-five eyes of 95 patients with PACG combined cataract were documented in this study. Twenty-two patients were male, and 73 were female. The age ranged from 46 to 85y old with a mean of(66±7) y. All patients were examined for endothelial cell count ( ECC ) , intraocular pressure ( IOP ) and best corrected visual acuity ( BCVA ) 1wk, 1, 2, 3 and 6mo after operation. Meanwhile, the range of anterior chamber closure and anterior chamber depth ( ACD ) were recorded before operation and postoperative 6mo. RESULTS: The mean IOP was 36. 1±4. 3mmHg ( 28-42mmHg) preoperatively and 15. 8±3. 5mmHg ( 8-28 mmHg)(1mmHg=0. 133kPa) 6mo after operation. There was a decreasing trend in IOP after operation( t=17. 173, PCONCLUSION: Phacoemulsification and IOL -implantation combined with goniosynechialysis is an effective method to treat PACG combined cataract. It can increase BCVA and decrease IOP. ECC decreases after operation, but it is in the normal range. It is a safe and effective operation mode.
ABSTRACT
?AIM:To investigate the measurement of central anterior chamber depth ( ACD ) in patients with acute primary angle - closure glaucoma ( APACG ) with A - scan ultrasound, Pentacam and ultrasonic biological microscope ( UBM) .?METHODS: Thirty-five patients (35 eyes) with APACG were selected, of whom central ACD were measured with A-scan ultrasound, Pentacam and UBM.?RESULTS: The measurement values of ACD with A-scan ultrasound, UBM and Pentacam were 1. 5633±0. 2089, 1. 5783 ± 0. 2067, 1. 6275 ± 0. 2296mm, which was equal variance tested by the homogeneity of variance, and was significant different by multiple comparision (F=4. 074, P=0. 026). The difference of ACD between the two groups of A-scan ultrasound and UBM, A-scan ultrasound and Pentacam, UBM and Pentacam were statistically significant ( P = 0. 032, 0. 023, 0. 012 ). Altman- Bland analysis showed that the three methods were not consistent with each other.?CONCLUSION: The ACD value of the APACG with the three methods is the largest using Pentacam, followed by UBM and A - scan ultrasound. In clinical the three methods with different advantages can complement each other, but cannot be replaced. In order to obtain more accurate results, we should combine the advantage and make comprehensive analysis.
ABSTRACT
AlM:To discuss the clinical effect and safety of the combined surgeries of phacoemulsification and goniosynechialysis for patients with primary angle -closure glaucoma ( PACG) .METHODS:Eighty-three eyes of 83 patients with PACG and cataract were ranomized into two groups. Group A:39 patients with 39 eyes of angle-closure 0. 05). The lOP in group A was lower than that in group B 3mo after operation, there was statistical significance (P<0. 05).CONCLUSlON:Phacoemulsification and goniosynechialysis can deepen ACD significantly. This method make the anterior chamber angle open, can reduce lOP and improve the patients’ visual acuity, especially in patients with PACG. lt is a safe and effective approach to patients with PACG and cataract.
