[Imaging features of Fuchs endothelial corneal dystrophy]

Area of Science:

• Ophthalmology
• Corneal Diseases
• Diagnostic Imaging

Background:

• Fuchs endothelial corneal dystrophy (FECD) is a progressive corneal disease affecting the endothelium.
• Accurate diagnosis and staging are crucial for effective management.
• Imaging modalities play a vital role in characterizing FECD.

Purpose of the Study:

• To investigate the characteristic imaging features of FECD using specular microscopy and in vivo confocal microscopy (IVCM).
• To provide imaging evidence to support the diagnosis and staging of FECD.
• To evaluate the utility of these imaging techniques in clinical practice.

Main Methods:

• Retrospective case series of 128 eyes from 64 patients diagnosed with FECD.
• Analysis of clinical data, including disease stage.
• Examination of imaging features obtained via specular microscopy and IVCM.

Main Results:

• Specular microscopy showed increased dark 'holes,' incidence, and fusion rates with disease progression.
• IVCM revealed an increase in guttata and a progression in their fusion patterns (pair-like, chain-like, group-like).
• Significant differences in specular microscopy findings were observed across FECD stages (P=0.000), with increasing peripheral corneal fusion from Stage II to IV (P=0.000).

Conclusions:

• Imaging features from specular microscopy and IVCM are valuable for the early diagnosis of FECD.
• Specular microscopy serves as a practical tool for rapid FECD screening.
• IVCM is essential for detailed analysis of guttata and fusion patterns, aiding in FECD staging and differentiation.
