Corneal Cell Morphology in Keratoconus: A Confocal Microscopic Observation

Area of Science:

• Ophthalmology
• Corneal Science
• Confocal Microscopy

Background:

• Keratoconus is a progressive corneal ectasia.
• Understanding corneal cell morphology is crucial for diagnosis and management.
• In vivo confocal microscopy offers detailed cellular visualization.

Purpose of the Study:

• To evaluate and compare corneal cell morphology in keratoconus patients and healthy controls.
• To assess changes in corneal cell morphology across different severities of keratoconus.
• To utilize in vivo slit-scanning confocal microscopy for detailed analysis.

Main Methods:

• A cross-sectional study involving 47 keratoconus patients and 32 healthy controls.
• Corneal cell morphology assessed using an in vivo slit-scanning confocal microscope.
• Qualitative and quantitative data analyzed using grading scales and specialized software.

Main Results:

• Significant differences in corneal cell morphology between keratoconus and healthy eyes, except for endothelial cell density.
• Progressive stromal haze, altered keratocyte nuclei, and stromal cell clustering observed with increasing keratoconus severity.
• Significant differences in stromal keratocyte densities and cell areas across keratoconus stages.

Conclusions:

• Confocal microscopy demonstrates distinct corneal cell morphology changes in keratoconus compared to healthy corneas.
• Corneal cell morphology alterations correlate significantly with keratoconus severity.
• Insights into these cellular changes can aid in the long-term monitoring and management of keratoconus.
