Pregnancy Clinical Trial
Official title:
Evaluation of Choroidal Thickness During Pregnancy Using Enhanced Depth Imaging Optical Coherence Tomography
The purpose of this study is to evaluate choroidal thickness and volume during the third trimester of pregnancy by comparison with a group of age-matched non-pregnant healthy group of women
Pregnant women in the last trimester and age-matched healthy controls have an Optical
Coherence Tomography (OCT) image taken on the OCT Spectralis® device.
A map of the choroid in the macular area is constructed automatically. Choroidal thickness
and volume are calculated for the 9 subfields defined by the Early Treatment Diabetic
Retinopathy Study (ETDRS).
A comparative analysis between the two groups will be performed. As a secondary outcome
measure, the change in choroidal thickness of the pregnant group of women will be assessed
at 6 months postpartum by comparison to the 3rd trimester of pregnancy.
The OCT is a non-invasive examination that poses no risk to the mother or the fetus.
