Abstract

BACKGROUND: To define ocular variables that might affect the need for early use of reading glasses. METHODS: A retrospective, non-randomized clinical trial was conducted at an aero-medical center. The charts of 100 healthy male pilots who suffered from presbyopia were reviewed. All subjects had undergone a complete eye examination every year for 30 years. Ocular parameters measured at the ages of 20, 30, 40, 45, and 50 years were recorded. Individuals were divided into two groups: those who needed reading glasses at the age of 45 years or earlier (group 1) and those who had needed reading glasses after 45 years of age (group 2). RESULTS: Of all the ocular variables examined each year, two differed significantly between the two groups. Refraction at age 20 was 0.1+/- 0.3 D in group 1 and 0.0 +/- 0.3 D in group 2 ( P <0.05). Amplitude of accommodation at age 20 was 9.5 +/- 1.2 D in group 1 and 9.9 +/- 1.0 D in group 2 ( P <0.05). CONCLUSION: Hyperopia and low amplitude of accommodation at the age of 20 might predispose to early development of presbyopia in normal individuals.
