The cornea in diabetes mellitus

Area of Science:

• Ophthalmology
• Endocrinology
• Cell Biology

Background:

• Diabetes mellitus affects multiple corneal layers, including epithelium, stroma, and endothelium.
• Diabetic corneal changes disrupt tissue homeostasis, impacting both normal and stressed conditions.
• These alterations manifest as various primary and postoperative complications.

Purpose of the Study:

• To elucidate the impact of diabetes mellitus on corneal morphology, metabolism, physiology, and clinical presentation.
• To investigate the role of the polyol pathway in diabetic corneal pathophysiology.
• To explore the therapeutic potential of targeting the polyol pathway for diabetic eye conditions.

Main Methods:

• Review of existing literature on diabetes and corneal pathology.
• Analysis of morphological, metabolic, and physiological changes in the diabetic cornea.
• Examination of the involvement of the polyol pathway in disease mechanisms.

Main Results:

• Diabetes induces significant morphological alterations across all corneal layers.
• Disruption of corneal homeostasis by diabetes leads to diverse clinical manifestations.
• The polyol pathway is identified as a key factor in diabetic corneal disease pathogenesis.

Conclusions:

• Diabetes mellitus profoundly affects corneal structure and function.
• The polyol pathway is crucial in the development and potential treatment of diabetic corneal complications.
