Primary Outcomes

Choroidal thickness
time frame: 3rd trimester of pregnancy (from 28 weeks gestation to delivery)

Secondary Outcomes

Change in choroidal thickness
time frame: During the 3rd trimester (from 28 weeks gestation to delivery) and at 6 months post partum

Eligibility Criteria

Female participants of any age.

Inclusion Criteria: Pregnant women: - uncomplicated pregnancy in the third trimester (from 28 weeks of gestation) For both groups: - no systemic or ocular disease - absence of systemic medication other than prenatal vitamins - no smoking habits - emmetropia or a small refractive error (spherical equivalent <1.5 diopters) Exclusion Criteria: - any of the above

Additional Information

Official title Evaluation of Choroidal Thickness During Pregnancy Using Enhanced Depth Imaging Optical Coherence Tomography
Principal investigator Renata Rothwell, Dr
Description 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.
