Abstract


This work is about investigation of condition of intraocular pressure (IOP) after intravitreous injection of medicine avastine into eyeball with normal hydrodynamic. Injections were made for treatment of neovascular chorioretinal membrane plainly. The medicine was injected intravitreously in volume 0,05 ml with a special needle 30 gauge. IOP was measured by special surgical ophthalmotonometer of own construction. Measuring of IOP were made before injection, and also 30 seconds, 3 and 5 minutes after injection. Just after injection we discovered that IOP rose to 65 mm of hydrargerum. 5 minutes after IOP dropped down to 27 mm. Patients didn't have any pains or other unpleasant feelings in the eyeball although the IOP was very high at the moment.
