ABSTRACT
INTRODUCTION:
Addition in patients of less than 40 years is not uncommon in our practice. We investigated the need for addition after objective refraction and thus determine the average age of onset of the presbyopia.METHODS:
We conducted a cross-sectional descriptive study of patients aged 35-45 years at the Central Hospital of Yaoundé over a period of three months. All patients underwent cycloplegic refraction. Distance visual acuity was corrected after instillation of cycloplegic eye drops while near addition was assessed two days later when the cycloplegia was no longer effective. Possible additional distance correction was done 2 days after cycloplegia. Statistical analysis was done using IBM SPSS 20.0 software.RESULTS:
We examined 55 patients, 110 eyes. The average age of patients was 41.87±2.5 years, the sex-ratio was 0.28. There was a female predominance. Hypermetropic astigmatism was the most common ametropia (58.2% of cases) followed by hyperopia (24.6%).No patient was myopic. the average age of presbyopia onset in this age group was 43.2±1.7 years. After objective correction of distance visual acuity, no patient needed for addition before the age of 40. Moreover, 4 out of 10 patients with hypermetropic ametropia did not need addition before the age of 40. Addition was significantly associated with age.CONCLUSION:
The average age of presbyopia onset is 43.2±1.7 years. Before the age of 45, addition must be preceded by objective refraction.Palavras-chave
