Overview
Age-related macular degeneration (AMD) and diabetic retinopathy are among the most common disorders causing visual disability in elderly people. AMD leads to dysfunction and loss of photoreceptors in the central retina. Neovascular AMD (nAMD) affects visual function early in the disease process.
The purpose of the study is to evaluate the effect of switching from ranibizumab therapy to the current routine therapy using aflibercept in eyes with treatment naive, recurrent or persistent nAMD, treatment naive diabetic retinopathy and pretreated diabetic retinopathy.
20 patients with recurrent or persistent nAMD, previously treated with intravitreal ranibizumab for up to one year will be included in this trial. Patients will be examined in monthly intervals over 12 months follow-up.
Examinations carried out will include: Best-corrected visual acuity (BCVA) using ETDRS charts at 4m distance, Reading Performance (RP), Standard ophthalmic examinations (SOE incl. funduscopy and applanation tonometry), Optical coherence tomography (OCT), Autofluorescence fundus image (AF) & red-free autofluorescence fundus image (RF), Color fundus photography (CFP), Fluorescein angiography and indocyaningreen angiography (FLA/ICG), Microperimetry (MP), as well as Non-invasive OCT based optical angiography (AngioVue).
