Оценка микроциркуляции на диске зрительного нерва при кератоконусе

Evaluation of Microcirculation at the Optic Nerve Head in Eyes With Keratoconus.

Keratoconus is a progressive bilateral disorder characterized by corneal thinning and anterior protrusion, leading to irregular astigmatism and reduced visual acuity. It has traditionally been regarded as a relatively rare condition. However, recent epidemiological studies have revealed that keratoconus is more common than previously thought. Hashemi et al.¹ reported a global prevalence of 1.38 per 1000 individuals (95% confidence interval [CI], 1.14–1.62) in a meta-analysis including over 7 million participants across 29 countries. A recent Japanese population-based study found that 0.85% of individuals aged over 35 years were diagnosed with keratoconus, and an additional 1.46% were classified as keratoconus suspects.² These findings indicate that keratoconus is not uncommon in clinical practice.
