Index: Age related changes in refractive index (cortical sclerosis) can cause hypermetropia. Another cause of index hypermetropia is diabetes. [2] Occasionally, mild hypermetropic shift may be seen in association with cortical or subcapsular cataract also. [12] Positional: Positional hypermetropia occur due to posterior dislocation of Lens or ...
There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.
Diabetic retinopathy (also known as diabetic eye disease) is a medical condition in which damage occurs to the retina due to diabetes.It is a leading cause of blindness in developed countries and one of the lead causes of sight loss in the world, even though there are many new therapies and improved treatments for helping people live with diabetes.
He never experienced losses in subjective best-corrected acuity, color vision or stereopsis. This case is interesting because the astronaut did not have disc edema or choroidal folds, but was documented to have nerve fiber layer (NFL) thickening, globe flattening, a hyperopic shift and subjective complaints of loss of near vision.

Diabetes is the most common cause of retinopathy in the U.S. as of 2008. [4] Diabetic retinopathy is the leading cause of blindness in working-aged people. [ 5 ] It accounts for about 5% of blindness worldwide and is designated a priority eye disease by the World Health Organization.
The study, which was published in Nature Medicine on January 20, analyzed data from more than 2 million people with diabetes who took GLP-1 receptor agonist medications like Ozempic and Wegovy.
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
The causes of macular edema are numerous and different causes may be inter-related. It is commonly associated with diabetes.Chronic or uncontrolled diabetes type 2 can affect peripheral blood vessels including those of the retina which may leak fluid, blood and occasionally fats into the retina causing it to swell.
