Brief Summary in Scientific Language

Different exsudative diseases of the macula (e.g. age related maculopathy (AMD), diabetic macular edema (DME), macular edema in retinal vein occlusion (RVO), myopic choroidal neovascularisation (CNV)) are currently treated by intravitreal injection of VEGF inhibitors. The official recommendations of the german ophthalmological associations (DOG, BVA, RG) include that affected patients shall be controlled in monthly intervals after the end of treatment. These controls require a high logistic support for both patients and examiner (time, transport, devices). The aim of this study is to investigate wether subjective parameters (estimation of the visual acuity and the metamorphopsia) can help to detect reliably a reactivation of disease. For this purpose we plan to compare the current gold standard of clinical examination (visual acuity, morphologic examination with the optical coherence tomography (OCT)) with the above-named subjective parameters. We try to identify patient groups in which the control interval might be adapted. Different diseases (AMD, DME, RVO, myopic CNV) shall be analyzed. In a second step the correlation between subjecitve parameters and morphologic parameters shall be investigated.

Interventions/Observational Groups

  •   non-interventional study
    retrospective data analysis of all patients who were examined in the clinical "IVOM-OCT-consultation" (clinical control of the success of treatment about 8 weeks after the last intravitreal injection, 4 weeks after the first control of success). If several appointments in the "IVOM-OCT-consultation" have taken place only the first documented appointment will be analysed (analysis of the documented subjective
    estimation of visual acuity and metamorphopsia, analysis of the documented visual acuity, analysis of the executed OCT)

Primary Outcome

specificity and sensitivity of subjective parameter (e.g. visual acuity, metamorphopsia; evaluation of the subjective devolopment as defined by better / worse / equal) in the evaluation of activity of maculopathy in age related maculopathy, retinal vein occlusion, diabetic retinopathy and other maculopathies

end of 1:1-Block primary endpoint
start of 1:1-Block secondary endpoint

Secondary Outcome

Differences in specificity and sensitivity of the above-named parameter in different diseases, identification of characteristics of the morphology in reactivated disease, correlation of these characteristics with subjective parameter, correlation with basic data (eye function, age)
