[Problematic issues related to screening for diabetic retinopathy].

The aim of this paper is to highlight the importance of screening for diabetic retinopathy and the education of diabetic patients. The key prerequisite of an effective screening is close collaboration between health care professionals. Successful screening detects DR at early stages and helps to prevent severe visual loss. Two cases of proliferative DR exhibiting the most serious complications (vitreous haemorrhage, traction retinal detachment and combined traction and rhegmatogenous retinal detachment, neovascular glaucoma) are reported. The first comorbid patient lost her vision despite the adequate treatment. The second patient was successfully managed with pars plana vitrectomy with final visual acuity better to the preoperative value.
