Abstract Details


Diabetic retinopathy (DR) is one of the leading causes of blindness among adults (approximately 5% of global blindness). The risk of developing of visual loss decreases under proper control of the disease. Multimodal diagnostics and prompt treatment of eye pathology are an effective measure for preventing of blindness. In 2016 the Russia put into practice a widefield fluorescein angiography (WFA) on the Spectralis HRA+OCT (Heidelberg Engineering, Germany). PURPOSE is to determine the adequacy of panretinal laser coagulation in patients with proliferative diabetic retinopathy (PDR) under the control of WFA.


Kaluga branch of FGAU 'MNTK 'Eye Microsurgery' named after acad. S.N. Fedorov'.


57 patients (114 eyes) with the 1st type of uncompensated diabetes and PDR were examined. Their average age was 32 (from 20 to 45 years). All patients had incomplete PLPC (2-3 sessions). 4 months after the treatment the clinical picture revealed the regression of neovascularization in the LPC zones, ophthalmoscopically new sites of the proliferative activity were not detected in all cases. All patients were examined with WFA.


Circulated periphery non-perfusion and foci of intraretinal neovascularization behind the PLPC were found in 22 patients (44 eyes) (38.6%) that is why we performed total PLPC in these areas. Foci of peripheral ischaemia in areas less than 10 diameters of the optic nerve disc were found in 24 patients (46 eyes) (40.4%) but in a year period we performed total PLPC in 18 patients (36 eyes) with not compensate of diabetes and the development of proliferative activity. In 14 patients (24 eyes) the ischaemia wasn’t identified and in a year of observation we didn’t find a proliferative activity.


WFA should be performed in the primary diagnostic in all patients with uncompensated 1st type of the diabetes and the symptoms the poliferative activity to exclude ischaemic form of the disease and to select the optimal volume of PLPC.
