Prandial Presbyopia

Journal of Neuro-Ophthalmology, 2010
Loss of accommodation amplitude during eating (prandial presbyopia) is a rare phenomenon that has been reported in only 1 patient who had had head trauma. We report 2 patients who had not had head trauma and whose accommodative amplitudes, measured by dynamic retinoscopy, became markedly diminished within 1 minute of starting a meal and did not recover

Pharmacological Treatments for Presbyopia

Drugs & Aging, 2023
Accommodation is the change in dioptric power of the eye. It is a dynamic process that allows focusing on an object at all distances. In order to focus sharply, three physiological responses, known as the triad of accommodation, are produced by a change in pupil size, a change in shape and position of the lens, and ocular convergence. This is modulated

Accommodation and presbyopia

Ophthalmic and Physiological Optics, 1995
SummaryThe mechanism of accommodation has been studied for at least four hundred years. The most interesting aspect of accommodation is that its time course is well in advance of other physiological functions – it begins to decline by adolescence and is lost about two‐thirds of the way through the normal line span.
