High Blood Sugar Connection to Eye Diseases
Read on to learn more about the high blood sugar connection to eye diseases. How does glaucoma relate back to blood sugar? High blood. As diabetes and glaucoma (or ocular hypertension) coexist in many Therefore, we sought to determine the relationship between glucose. The relationship between diabetes and glaucoma can be controversial When blood sugar levels are high, the secreted insulin is ineffective at.

Although the above-mentioned studies did not evaluate the association between blood glucose levels variation and IOP changes specifically, we believe that our findings indirectly corroborate their results.
Regarding the association between glucose levels and IOP, there are scant data in the literature.
Larsen and colleagues [ 22 ] found lower IOP values during severe hypoglycemia. In addition, Traisman et al. Unfortunately, none of these studies sought to determine the association between the magnitude of glucose levels variation and IOP change in diabetic and nondiabetic patients, which hinders a straight comparison with our findings.
Nevertheless, we believe that our data are in agreement with these two latter studies, as we found a mean IOP increase of 2. Finally, the discrepancy in the literature results could be explained in part by the differences in studies designs and populations and possibly by the influence of other systemic associations such as hypertension, obesity, and other conditions that were not evaluated.
Several hypotheses have been created to explain the association between high glucose levels and IOP. Some researchers believe that there are genetic factors associated in family history of diabetes [ 24 ].
Other researchers agree with the idea that a diabetic person could have an autonomic dysfunction which would lead to an IOP increase [ 25 ]. However some authors believe that elevated blood glucose results in the induction of an osmotic gradient which leads to fluid shifts into the intraocular space [ 12 ].
At this point, we believe that it is important to discuss the main clinical implications of our findings.

Ophthalmologists often see diabetic patients on daily practice. Many of these diabetic patients already have glaucoma or ocular hypertension or are glaucoma suspects.
Although most attention is given to each 1 mmHg variation in IOP, the glycemic control is rarely taken into account. The fact that we also documented a significant association in nondiabetic individuals makes the influence of glycemic levels on IOP even more relevant.
It is important to stress and discuss some specific characteristics and limitations of the present study. First, it is limited by its small sample size; however, even with a small sample we found a significant association between blood glucose levels and IOP variation, especially in diabetic patients 20 patients. Second, glucose levels were assessed solely twice baseline and postprandial. Multiple measurements would have provided additional data and possibly allowed a more detailed analysis about the association between glucose variation and IOP change.
Third, the investigation of other systemic comorbidities by means of questionnaire may have been insufficient. Fourth, we did not correlate the duration of diabetes and IOP.

However, it is important to emphasize that previously published data indicate that whereas the duration of the diabetic disease is an important parameter for the incidence and severity of retinopathy, there is no such influence when it comes to IOP [ 2627 ]. Lastly, we used peripheral capillary blood for the glucose analysis.
This method is acceptable for patient self-monitoring or screening purposes.Dark Circles Under the Eyes
However, different studies showed evidences that peripheral capillary blood and venous antecubital fossa blood samples could be comparable and can have similar influence after meal [ 28 ]. In addition, further studies should be done to evaluate the causative relationship between glucose levels and IOP variation. It has certainly been shown that increased consumption of fruits and vegetables and a heart-healthy diet will help decrease risk of heart disease and diabetes, and this is what I often recommend to my patients who ask about diet and glaucoma.
More research needs to be done, however, to determine specific recommendations about antioxidants and glaucoma progression. Interestingly, in patients with early visual field loss that was close to the central vision, the association was even stronger 40 to 50 percent lower risk. Again, it is important to note that this association was examining the risk of glaucoma diagnosis, not progression or worsening of existing glaucoma.
Nevertheless, the advice to eat green leafy vegetables is probably a good one! Omega Fatty Acids A recently published prospective study found that a diet with a high omega 3: However, more studies are needed in order to determine whether recommending a diet with a lower omega 3: Omega-3 fatty acids are typically found in vegetable oils, green vegetables such as kale, and fatty fish such as salmon. Omega-6 fatty acids are found in many types of vegetable oils and can help lower LDL cholesterol.
Supplements Another common question is whether there are any supplements that can be taken to reduce the risk of glaucoma or to treat glaucoma.
Currently, there is no convincing data that supplementation can help in preventing or treating glaucoma.
Please note that there is a specific supplement intervention, however, that could delay and possibly prevent intermediate age-related macular degeneration from progressing to the advanced stage. It is very important to ask your ophthalmologist if this supplement would be beneficial to you if you have macular degeneration. Summary Clearly, there is still much to be learned about the relationship between diet and glaucoma.
