“…flax and soy) may improve the performance on short wavelength-automated perimetry in postmenopausal females (Eisner & Demirel 2011). There is also evidence that visual sensitivity improves in pregnancy, being greatest in the third trimester when oestrogen levels are at their highest (Akar et al 2005). Contrast sensitivity is lower in postmenopausal than in premenopausal women (Siesky et al 2008), particularly at high spatial frequencies (between 9 and 18 cycles/degree), and improves after hormone therapy (Guaschino et al 2003).…”

Over the past 10 years, a literature has emerged concerning the sex steroid hormone oestrogen and its role in human vision. Herein, we review evidence that oestrogen (oestradiol) levels may significantly affect ocular function and low-level vision, particularly in older females. In doing so, we have examined a number of vision-related disorders including dry eye, cataract, increased intraocular pressure, glaucoma, age-related macular degeneration and Leber's hereditary optic neuropathy. In each case, we have found oestrogen, or lack thereof, to have a role. We have also included discussion of how oestrogen-related pharmacological treatments for menopause and breast cancer can impact the pathology of the eye and a number of psychophysical aspects of vision. Finally, we have reviewed oestrogen's pharmacology and suggest potential mechanisms underlying its beneficial effects, with particular emphasis on anti-apoptotic and vascular effects.

Pregnancy represents a real challenge to all body systems. Physiological changes can involve any of the body organs including the eye and visual system. The ocular effect of pregnancy involves a wide spectrum of physiologic and pathologic changes. The latter might be presenting for the first time during pregnancy such as corneal melting and corneal ectasia, or an already existing ocular pathologies that are modified by pregnancy such as diabetic retinopathy and glaucoma. In addition, pregnancy can affect vision through systemic disease that are either specific to the pregnant state itself such as the pre-eclampsia/eclampsia and Sheehan's syndrome, or systemic diseases that occur more frequently in relation to pregnancy such as Graves’ disease, idiopathic intracranial hypertension, anti-phospholipid syndrome, and disseminated intravascular coagulation.

PurposeThe inspection of foveal and parafoveal thickness in healthy pregnant women in the last trimester.Materials and methodsThis study included 40 healthy pregnant women in their last trimester (study group: 40 women, 80 eyes) and 37 nonpregnant women (control group: 37 women, 74 eyes). Visual acuity, intraocular pressure, slit lamp examination of anterior and posterior segments, and visual field examination with automated perimetry were performed in both groups. Foveal and parafoveal thickness in the four quadrants (upper, nasal, temporal, and inferior parafoveal) and peripapillary retinal nerve fiber layer were measured by optical coherence tomography. There were no systemic or ocular problems in either group. Findings were analyzed with statistical software. A P value <0.05 was considered statistically significant.ResultsMean foveal and parafoveal thicknesses in the study group were: foveal 236.12 ± 27.28 μm, upper quadrant 321.31 ± 12.28 μm, temporal quadrant 307.0 ± 12.05 μm, inferior quadrant 317.0 ± 10.58 μm, and nasal quadrant 313.62 ± 14.51 μm. Mean foveal and parafoveal thicknesses in the control group were: foveal 224.62 ± 21.19 μm, upper quadrant 311.62 ± 12.71 μm, temporal quadrant 296.87 ± 13.78 μm, inferior quadrant 305.43 ± 13.25 μm, and nasal quadrant 304.93 ± 13.44 μm. Mean retinal nerve fiber layer thicknesses in the study and control group were 110 ± 12.4 μm and 108 ± 13.1 μm, respectively.ConclusionMean retinal thickness in pregnant women was higher than control group in all measurements. Statistically significant difference in thickness was only found in upper, temporal, and inferior parafoveal areas.
