Retina scan pregnancy9/23/2023 Subjects with any previous ocular surgery or ocular pathology including refractive disorders with spherical equivalent greater than ± 1.0 diopters were excluded. Participants underwent an interview with demographic and background history and complete ophthalmic examination. This study was approved by HCPA research ethics committee and was conducted in accordance with the Declaration of Helsinki guidelines. All participants received in person full explanation about the study and provided written informed consent. The participants were recruited between March and September of 2016 at Hospital de Clinicas de Porto Alegre (HCPA), Brazil. This cross-sectional study included 122 eyes of 61 women, divided into two groups: 27 healthy pregnant women in the third trimester and 34 age-matched healthy non-pregnant women. The aim of this study was to compare choroidal thickness measurements of healthy women, pregnant and non-pregnant, using EDI-OCT. Since it is a noninvasive diagnostic method, EDI-OCT would be ideal for the study of choroid changes during an uncomplicated pregnancy. EDI-OCT promotes better documentation of the choroid and choroidal–scleral interface by decreasing signal strength posterior to the retinal pigment epithellium. The development of the enhanced depth imaging (EDI) technique of spectral-domain optical coherence tomography (SD-OCT) systems allowed analysis of choroidal morphologic features in normal and pathological eyes. Choroidal dysfunction and ischemia are also a common ocular complication of preeclampsia. A strong association of central serous chorioretinopathy and pregnancy is well documented. The impact of pregnancy on the choroid, however, is still under investigation, with mixed results. Changes in ocular blood flow may also occur, as an increased pulsatile ocular blood flow. Ocular changes during pregnancy like an increased central corneal thickness and curvature and decreased corneal sensitivity and intraocular pressure (IOP) were already described. Cardiac output is increased as early as the 5th week and reflects a reduced systemic vascular resistance and an increased heart rate. Volemia augmentation in pregnancy averages 40–45% above the nonpregnant blood volume after 32–34 weeks. Physiological changes during pregnancy are significant and their knowledge is essential to optimize outcomes. Our study showed no statistically difference in choroidal thickness between healthy non-pregnant women and healthy pregnant women in the third trimester. There was also no statistically significant association between gestational age and choroidal thickness measurements in the healthy pregnant women group. Mean subfoveal choroidal thickness was 304.1 + 9.6 µm in the control group and 318.1 + 15.6 µm in the pregnant women group (p = 0.446). There were no significant differences in the ten measurements of choroidal thickness comparing both groups. Choroidal thickness was measured using Enhanced Depth Imaging OCT at ten different locations: at the fovea and every 500 µm from the fovea up to 2500 µm temporally and up to 2000 µm nasally. The aim of this study is to compare choroidal thickness measurements of healthy pregnant women in the third trimester and healthy non-pregnant women using spectral-domain optical coherence tomography (OCT). The doctor moves the ultrasound wand against the front surface of your eye.The impact of pregnancy on the choroid is still under investigation. Then the doctor gently moves a small ultrasound wand against your eyelid.Įyes open: Eyedrops are used to numb your eyes. The doctor puts ultrasound gel on your eyelid. This test usually takes about 30 minutes.Įyes closed: You sit in a chair with your eyes closed.Photos are taken as the dye enters the eyes.It takes only a few seconds for the dye to be visible in the blood vessels in your eyes. An IV needle is placed in a vein in your arm, and the dye is injected.Angiogramīefore an angiogram, a dye is injected into your vein. It only takes a few minutes to take the pictures. You can breathe and blink normally while the camera photographs or scans your eyes. Keep your mouth closed, open your eyes as wide as you can, and stare straight ahead. And you'll brace your forehead against a bar to keep it still. You'll sit and wait for about half an hour for the drops to take effect.įor most tests, you'll sit in a chair facing the camera. Retinal imaging tests are done in a hospital or doctor's office.įor some tests, the doctor will first use eyedrops to widen, or dilate, your pupils.
