METHOD FOR PREDICTING RETINAL NEOVASCULARIZATION IN CASE OF DIABETIC RETINOPATHY Russian patent published in 2005 - IPC

FIELD: medicine, ophthalmology.

SUBSTANCE: the present innovation deals with predicting the appearance of retinal neovascularization at early stages of proliferative diabetic retinopathy, that is at transition of nonproliferative diabetic retinopathy into proliferative stage. One should perform dynamic electroretinography to calculate glial index K_G. Moreover, index values should be calculated by the ratio of b-wave amplitude from wave-a peak up to wave-b peak against amplitude of R3 subcomponent of low-frequency RERG for flashings at frequency of 8-12 Hz. Electroretinographic studying to calculate patient's glial index should be repeated every 2-3 mo and at decreased K_G by 2.5 U and more against its increased value in previous trial one should diagnose the first signs of retinal neovascularization. The innovation in question enables to prescribe laser therapy in due time to prevent severe complications of progressing proliferative process.

EFFECT: higher accuracy of diagnostics.
