TEL-HASHOMER, Israel — Hyperopia and low amplitude of accommodation at the age of 20 may predispose normal individuals to the early development of presbyopia, according to a study conducted here.

In a retrospective, non-randomized clinical trial, Abraham Spierer, MD, and Benjamin Shalev, MD, reviewed the charts of 100 healthy male pilots with presbyopia. All patients had undergone a complete ophthalmic examination every year for 30 years. Patients were divided into two groups: those who needed reading glasses before age 45 and those who needed them after age 45.

The men who needed glasses before age 45 had slight hyperopia (mean of +0.1 D) and slightly lower amplitude of accommodation (mean 9.5 D) than the men who did not need glasses until after the age of 45.

The study was published in the February issue of Graefe’s Archive for Clinical and Experimental Ophthalmology.
