Abstract:
Objective To investigate the factors associated with short-term elevation ofintraocular pressure after ranibizumab intravitreal injection.Methods 292 eyes of 292 patients who were diagnosed retinopathy and suitable to receive ranibizumab intravitreal injection were enrolled in this prospective clinical study.There were 157 males and 135 females.193 patients diagnosed with age-related macular degeneration and 99 other retinopathy patients.Mean age of patients was 62.75 ± 13.74 years.All subjects underwent systemic and comprehensive ophthalmology examinations.The mean BCVA was 0.68± 0.47 logMAR.Mean basal intraocular pressure was 18.1 mmHg (1 mmHg=0.133 kPa).All patients received intravitreal injection with 0.05 ml of ranibizumab (0.5 mg).The intraocular pressure were measured by non-contact tonometer at 10,30,120 minutes and 1 day after injection in a sitting position.The patients were grouped by the changes ofintraocular pressure 10 minutes after injection.The elevation was more than 10 mmHg as elevation group and less than 10 mmHg as stable group.Analyze the possible related factors with elevation of intraocular pressure after ranibizumab intravitreal injection by comparing the different datum of two groups.Results The mean intraocular pressure were 23.8,20.5,19.9 and 17.4 mmHg at 10,30,120 minutes and 1 day after injection.The significant elevation level were 5.8,2.4,1.8,-0.7 mmHg compared with basal intraocular pressure.Among 292 eyes,intraocular pressure elevation in 68 eyes and stabled in 224 eyes.The age (Z=-0.732),gender (x2=1.929),right or left eye (x2=2.910),BCVA (Z=-0.039),diseases ((2=2.088) were no significant difference between two groups (P＞0.05).The injection number (Z=-2.413,P=0.001),basal intraocular pressure (Z=-3.405,P=0.016) and elevations after injection (Z=-11.501,-8.366,-5.135,-3.568;P＜0.01) were significantly different comparing two groups (P＜0.05).By logistic regression analysis,basal intraocular pressure was positively correlated with the elevation of intraocular pressure 10 minutes after injection (B=-0.844,OR=0.43,95％CI 0.24-0.76,P=0.004).Patients with higher basal intraocular pressure may occur intraocular pressure elevation after ranibizumab intravitreal injection much probably.Conclusions The factors associated with short-term elevation of intraocular pressure after ranibizumab intravitreal injection were basal intraocular pressure.The higher basal intraocular pressure,the higher risk to gain elevation of intraocular pressure after injection.
