Hemodynamics of the eye during combined treatment of severe proliferative diabetic retinopathy

Diabetic retinopathy (DR) is a severe late neuromicrovascular complication of diabetes mellitus. Panretinal laser photocoagulation is a method of choice of DR treatment; antiangiogenic therapy applies if necessary. The traction development, hemophthalmos, and retinal detachment are the most common complications of proliferative DR and needs vitreal surgery. Ultrasound examination with blood flow assessment and laser speckle flowography (LSFG) are very useful methods in retinal blood flow detecting. Purpose of the study: to conduct blood flow parameters using ultrasound dopplerography with assessment of blood flow and LSFG in 67-year-old patient with bilateral severe proliferative DR after panretinal photocoagulation, avitria, pseudophakia and stable ophthalmological status. Patient observed a significant decrease in retinal blood flow and normal values of choroidal blood flow, combined with rather high visual acuity. Conclusion. Choroidal blood flow plays a significant role in maintenance of visual functions. Study of eye hemodynamic status by ultrasound dopplerography and LSFG is effective in DR patients. Quantitative and qualitative blood flow control proved usefulness in clinical practice and requires further study.
