    The Role of Dyslipidemia Control in the Progression of Diabetic Retinopathy in Patients with Type 2 Diabetes Mellitus.
    Diabetes Ther 2017 Feb 28. Epub 2017 Feb 28.
    2nd Department of Ophthalmology, University of Athens, Athens, Greece.
    Diabetic retinopathy (DR) is a common microvascular complication of diabetes mellitus (DM) and is considered as the leading cause of visual impairment in working-aged adults worldwide. Dyslipidemia has been associated with DR, but not with progression to the proliferative form of DR, although the exact role in the pathogenesis of DR and diabetic macular edema (DME) remains controversial. As a result, a reasonable question arising is whether control of dyslipidemia may alter the course of DR. Read More

    Background Laser therapy is an important treatment option in retinal diseases, especially in cases of vascular involvement. Most approaches are based on coagulation of retinal structures. As there is increasing use of agents targetting vascular endothelial growth factor in the treatment of macular diseases, indications for the use of laser treatment need to be reviewed carefully, especially with respect to their significance in first line therapy.

    Panretinal photocoagulation (PRP) is a standard treatment for proliferative diabetic retinopathy. Conventional laser (CL) therapy is performed in one or more sessions in single spot mode. Visual disabilities have been reported after treatment with CL, including central vision loss due to macular edema and peripheral visual field loss resulting from extensive inner retinal scarring.

    Ophthalmology Department and Ophthalmic Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
    Purpose: To determine the clinical efficacy of extended targeted retinal photocoagulation (ETRP) compared to conventional panretinal photocoagulation (CPRP) in proliferative diabetic retinopathy (PDR).

    Methods: In a single-masked randomized clinical trial, 270 eyes of 234 patients with naïve early or high-risk PDR were randomly assigned to receive either CPRP or ETRP (135 eyes, each treatment arm). Best-corrected visual acuity (BCVA) measurement, fundus examination, wide-field fluorescein angiography (WFFA) and optical coherence tomography were carried out before and 3 months after retinal photocoagulation.
