According to American Academy of Ophthalmology (AAO):
“The frequency of ocular examinations should be based on the presence of visual abnormalities and/or the probability of visual abnormalities developing. Individuals who have ocular symptoms require prompt examinations. Individuals who do not have symptoms but who are at high risk of developing ocular abnormalities related to systemic diseases such as diabetes mellitus and hypertension or who have a family history of eye disease require periodic comprehensive eye examinations.”
AAO recommends eye examinations for those who do not have any eye abnormalities as follows:
1. Infants should have eye examination before the age of three months.
2. Subsequent assessments should be done on routine health supervision visits.
3. School-age children should be evaluated every 1 to 2 years for visual acuity and ocular alignment.
1. At least one eye examination between the ages of 20 and 29.
2. At least twice between the ages of 30 and 39.
3. Every 2 to 4 years for individuals aged 40 to 54 years old.
4. Every 1 to 3 years for individuals who are 55 to 64 years old.
5. For 65 years or older age, it should be every 1 to 2 years.
The children who do not have any abnormality of the eyes but have family history of some disease, for example retinoblastoma (an eye cancer of children) and some metabolic disorders should be examined more frequently.
Similarly adults who have family history of some diseases, for example glaucoma or have some systemic disease (for example diabetes) which could potentially affect the eyes or have some risk factors of various eye diseases should be examined more frequently.
For those who have some ocular symptoms or eye abnormalities, an evaluation by an ophthalmologist is required. The frequency of further examinations depends on the disease or condition, the age of the individual, the type of the treatment and the response to treatment.
