RESUMEN
Objective To observe clinical efficacy of brinzolamide on mechanical contusion ocular trauma . Methods 50 patients(57 eyes) of mechanical contusion ocular trauma were selected and divided into observation group and control group randomly and evenly ( 29 eyes in the observe group ,28 eyes in the control group ) .On the basis of mechanical contusion ocular trauma basic treatment for all the patients , the observing group was added brinzolamide ophthalmic suspension .Their vision , intraocular pressure and ERG were observed .Results The vision of patients in the observing group was obviously better than that in the control group (χ2 =4.49,P<0.05).Intraocular pressure in the observing group (14.88 ±0.83)mmHg was obviously lower than that in the control group (19.64 ± 2.30)mmHg(P<0.05).Sum of a-wave amplitude and sum of b-wave amplitude after treatment were better than those before treatment ,and those in the observing group were higher than theose in the control group ( observation group:ta =0.44,tb =0.24;the control group:[ ta =1.03,tb =0.32;between two grous:ta =3.35,tb =2.37,P<0.05 ) ] .Conclusion Using Brinzolamide ophthalmic suspension to treat mechanical contusion ocular trauma preven -tively can obviously improve patients′vision, control their intraocular pressure and promote the recovery of retinal function.It has positive clinical effect .
