An Association Between Large Optic Nerve Cupping and Cognitive Function.

ABSTRACT:

Purpose

To determine if a larger cup-to-disc ratio is associated with poor cognitive function in postmenopausal women without glaucoma or ocular hypertension.

Methods

We used data from the Women's Health Initiative (WHI) hormone trial, originally designed to test effects of hormone therapy (HT) on various health outcomes. Large cup-to-disc ratio was defined as greater than 0.6 in either eye based on stereoscopic optic nerve photographs. Global cognitive function was assessed annually by Modified Mini-Mental State Examination (3MSE) in the WHI Memory Study. Exclusions were no information on optic nerve grading; no 3MSE scores at the time of the eye examination, ocular hypertension (intraocular pressure >23 mm Hg, Goldmann applanation tonometry), or glaucoma medication use. A generalized linear model for log-transformed 3MSE scores was used for determining the association between large cup-to-disc ratio and 3MSE scores, adjusting for age, race, diabetes, body mass index, cardiovascular disease, smoking, HT randomization, education, and diabetic retinopathy.

Results

Analyses included 1636 women (mean age ± standard deviation, 69.57 ± 3.64 years; 90.39% white). Of those, 122 women had large cup-to-disc ratio. The mean 3MSE scores in women with vs without large cup-to-disc ratio were 95.4 ± 6 vs 96.6 ± 5. In the adjusted model, women with large cup-to-disc ratio had statistically significantly lower 3MSE scores, compared with those without large cup-to-disc ratio, yielding the predicted mean difference in 3MSE scores of 0.75 with a standard error of 0.05 units (P = .04).

Conclusions

Postmenopausal women who had large cup-to-disc ratio without glaucoma or ocular hypertension exhibited lower global cognitive function. Further investigation is warranted. NOTE: Publication of this article is sponsored by the American Ophthalmological Society.

Project description:PurposeTo determine normative values of retinal nerve fibre layer thickness (RNFL) and optic nerve head (ONH) parameters and their association with routine clinical tests such as refractive error (RE), stereoacuity (SA), and contrast sensitivity (CS) in an African population.MethodsIn a cross-sectional observational study, 100 normal subjects aged 20 to 78 years were evaluated using the Cirrus HD-OCT 5000 and matched with 200 glaucoma patients.ResultsAverage (±SD) RNFL thickness for normal subjects was found to be 102.37 ± 7.45 (range, 82-119 microns) compared with 90.74 ± 14.50 found for glaucoma subjects. Females had higher average RNFL values (104.84 ± 6.90) compared with males (99.80 ± 7.18). Significant associations were calculated between quadrant RNFL thickness and SA, SE, and CS (all p < 0.05). The mean cup to disc ratio (CDR) was 0.49 ± 0.12, and mean optic disc area (DA) was 2.08 mm2 ± 0.40. Smaller DA was recorded for participants aged 60+ years (1.86 ± 0.25), followed by 40-59 age group (2.01 ± 0.41) and then 20-39 age group (2.19 ± 0.41). Significant associations were calculated between SA and ONH parameters, except rim area (all p < 0.05). The mean cup to disc ratio (CDR) was 0.49 ± 0.12, and mean optic disc area (DA) was 2.08 mm2 ± 0.40. Smaller DA was recorded for participants aged 60+ years (1.86 ± 0.25), followed by 40-59 age group (2.01 ± 0.41) and then 20-39 age group (2.19 ± 0.41). Significant associations were calculated between SA and ONH parameters, except rim area (all p < 0.05).

Significant associations were calculated between SA and ONH parameters, except rim area (all.ConclusionRNFL thickness in healthy black Ghanaian population was significantly higher than that reported in other races. The values and associations reported in this study can inform clinical decision on the normal variation in RNFL and optic disc parameters.
