Presbyopia: Pathogenesis and clinical findings

 • Presbyopia is part of the normal ageing of the lens and its capsule, ciliary body, and zonular fibres 

 • Conditions such as diabetes, Multiple Sclerosis, heart disease, and Myasthenia Gravis may precipitate presbyopia

 • Use of medications such as antihistamines, antidepressants, and diuretics may precipitate presbyopia

 => Presbyopia

 • Decreased elasticity of the lens -> Decreased ability to assist in accommodation

 • Decreased ability of the ciliary body to contract -> Decreased ability to enable accommodation

 => Light rays from near objects converge behind the retina
