About

The purpose of this study is to assess the influence of vitrectomy on changes in central choroidea and comparing the results in imaging of the choroidea with two different OCT devices.

This is a prospective, open, non-randomized, observational, MPG study This study will be performed at the Department of Ophthalmology, Medical University of Vienna.

40 Patients who undergo vitrectomy will be included into this study. The investigation will help to gain new information about the effects of vitrectomy on the choroid.

Full description

Since the development of new OCT modalities, like enhanced depth or swept-source OCT imaging, a better visualization and evaluation of retinal structures and the choroidea became possible. 23G Vitrectomy and membrane peeling seem to have an influence on posterior segment structures of the eye but data show no clear evidence evaluating those changes after surgery. Only little information is currently available on the influence or the changes resulting from vitreous surgery on the central choroidea. Hence, the aim of this study is to evaluate those influences resulting on choroidea using two different OCT devices.
