Clinical significance of common eye changes in older patients

The limbus is often affected by degenerative lesions, many associated with the aging process. Some degenerations may cause irritation, discomfort, and poor vision, thus requiring ophthalmological treatment, while a few require systemic evaluation and treatment. As the limbus is also subject to neoplasms and inflammatory processes, any limbal lesion whose identity is less than obvious should prompt an ophthalmologic consultation.
