Endothelial cell density changes are most commonly associated with corneal dystrophies. Corneal dystrophies are a group of genetic disorders that cause opacification or clouding of the cornea due to abnormal deposits of material or changes to the corneal structure, often affecting the corneal endothelial cells. These changes can lead to a reduction in the number of healthy endothelial cells, which are essential for maintaining corneal transparency and proper hydration.

In corneal dystrophies, the endothelial cells can become damaged or altered due to a variety of factors, including the accumulation of deposits or genetic mutations. This results in a decreased ability for the cornea to maintain its clarity and function. Monitoring endothelial cell density is an important part of assessing the health of the cornea, especially in patients with these conditions.

In contrast, retinal detachment, vitreous hemorrhage, and diabetic retinopathy primarily affect the internal structures of the eye and do not have a direct impact on corneal endothelial cells or their density. Therefore, changes in endothelial cell density are predominantly seen in corneal dystrophies.
