Abstract
Purpose :
To provide a severity scoring system for Fuchs’ endothelial dystrophy (FED) based on corneal specular microscope (CSMe) image patterns. As secondary purpose, horizontal cornea scoring was compared with vertical scoring to confirm previous studies that shows that exposed areas of the cornea can show worse endothelial patterns.
Methods :
A cross-sectional study involving 98 eyes of 49 patients with the clinical diagnosis of Fuchs’ endothelial dystrophy (FED) was performed at the Clinica de Olhos Dr. Fernando Abib (Curitiba, Brazil) and at Santa Casa de Misericordia de Sao Paulo (Sao Paulo, Brazil). Contact Corneal Specular Microscope (CSMe) (BioOptics, USA) was used to score the severity of FED based on CSMe endothelial profile (Figure 1). The following areas of the cornea were analyzed and scored by two different and independent examiners: Central (C), Superior (S), Superior Mid-Periphery (SMP), Inferior (I), Nasal (N), and Temporal (T). Results were expressed in average and standard deviation. Horizontal cornea scoring (C+N+T) was then compared with vertical cornea scoring (C+S+SMP+I) using Student’s t test with level of significance of 0.05
Results :
Horizontal cornea (3.00 ± 2.38) showed statistical difference scoring when compared to vertical cornea scoring (2.48 ± 2.34) (p=0.0014)
Conclusions :
Severity scoring system for FED was appropriate to classify the different areas of the cornea. Horizontal areas of the cornea seems to have a worse endothelial profile that the vertical areas
