Pathophysiology of Keratoconus: What Do We Know Today

Area of Science:

• Ophthalmology
• Corneal Diseases
• Pathology

Background:

• Keratoconus is a progressive corneal ectasia causing significant visual impairment.
• Abnormal protein expression is observed in keratoconic corneas, but disease mechanisms remain unclear.
• Existing research highlights morphological changes, yet a comprehensive understanding of pathogenesis is lacking.

Purpose of the Study:

• To review morphological studies of the keratoconic cornea.
• To correlate early morphological findings with current proteomic, biochemical, and cell culture data.
• To propose potential pathogenic pathways for keratoconus.

Main Methods:

• Literature review of morphological, proteomic, biochemical, and cell culture studies on keratoconus.
• Synthesis of findings from diverse study types.
• Postulation of pathogenic mechanisms based on integrated data.

Main Results:

• Morphological alterations in keratoconus provide foundational insights.
• Proteomic and biochemical studies reveal specific protein dysregulations.
• Cell culture models offer functional context for observed molecular changes.

Conclusions:

• Integrating morphological, molecular, and cellular data is crucial for understanding keratoconus.
• Specific pathogenic pathways involving protein abnormalities and cellular dysfunction are suggested.
• Further research is needed to elucidate and validate these pathways for therapeutic development.
