Introduction

Corneal dystrophies are a group of inherited, bilateral, and typically progressive disorders characterized by abnormal deposition of material within one or more layers of the cornea. These conditions often present with reduced corneal transparency, leading to visual impairment or discomfort, though severity varies depending on the type and progression of the dystrophy. Corneal dystrophies are generally non-inflammatory and may manifest at different ages, from childhood to adulthood [1]. Understanding their pathogenesis, clinical features, and management is essential for preserving vision and guiding treatment decisions.

Discussion

Corneal dystrophies are classified based on the corneal layer affected: epithelial, stromal, or endothelial. Epithelial dystrophies, such as epithelial basement membrane dystrophy, involve the corneal epithelium and are often associated with recurrent erosions and irregular corneal surfaces. Stromal dystrophies, including granular, lattice, and macular dystrophies, are characterized by abnormal deposits within the corneal stroma [2]. These deposits can lead to progressive opacification, reduced visual acuity, and in some cases, recurrent corneal erosions.

Endothelial dystrophies, such as Fuchs endothelial corneal dystrophy, primarily affect the innermost layer of the cornea. Endothelial cell dysfunction leads to corneal edema, loss of transparency, and gradual visual deterioration. Fuchs dystrophy often presents in middle age and is more common in females, with symptoms including blurred vision, glare, and sensitivity to light [3,4]. Histopathological examination typically reveals thickening of Descemetâ??s membrane, endothelial cell loss, and guttae formation.

Genetic mutations play a significant role in the development of corneal dystrophies. For example, mutations in the TGFBI gene are linked to several stromal dystrophies, while SLC4A11 mutations are associated with endothelial dystrophies. These mutations affect protein structure, cellular adhesion, or ion transport, leading to abnormal deposition or degeneration within the cornea [5].

Diagnosis relies on clinical examination using slit-lamp biomicroscopy, corneal topography, and confocal microscopy. Genetic testing may aid in confirming specific subtypes and guiding family counseling. Management depends on the severity of visual impairment and symptomatology. Mild cases may only require lubrication and protective measures, while advanced disease may necessitate surgical intervention such as phototherapeutic keratectomy or corneal transplantation.

Conclusion

Corneal dystrophies are a diverse group of hereditary corneal disorders that can significantly impact vision. Accurate diagnosis, genetic counseling, and timely intervention are key to preserving visual function. Advances in imaging and surgical techniques continue to improve outcomes, offering hope for patients affected by these progressive corneal conditions.
