INTRODUCTION

Accommodative insufficiency, the condition of which accommodanve power is constantly below the normal limit for the patient's age, is not uncommon in ophthalmlogical practice It may be due to undue sclerosis of the lens or weakness of the ciliary muscle. The symptoms are an inability to focus on near objects or sustain a clear reading for a reasonable period. Although the condition may be caused by switching from miotics agents like timolol, or giving stronger minus Iens myopic presbyopes, or uncorrected high hyperopia, most of the cases is drug induced.  Many systemic medication may have minor cycloplegic side effect, and interference with accommodative activity does occur when the dosage is excessive. Sometimes, the combination of two or more drug may accentuate and then reinforces the cycloplegic side-effect even though the dosage of both drugs are low. The following report is an example.
