A fundus examination enables detailed analysis of the retina, vitreous gel, optic nerve, and blood vessels through pupil dilation. With a fundus examination, many eye diseases that could lead to permanent vision loss, such as diabetic retinopathy, glaucoma, and macular degeneration, can be diagnosed and treated in their early stages. During routine eye health check-ups, numerous measurements like visual acuity, color vision, eye pressure, eye muscle movements, and light sensitivity in the eyes are conducted.
Should Be Done Once a Year
A fundus examination is a measurement that involves examining the back segment structures of the eye and should be included in routine eye examinations at least once a year. Before the fundus examination, the pupil is dilated with various drops for a more detailed inspection. Then, several conditions such as the consistency and color of the vitreous gel, the appearance of nerve fibers and retinal blood vessels, and the borders and color of the optic nerve are examined with the help of biomicroscopy or an indirect ophthalmoscope and lens.
Due to the use of an ophthalmoscope in the examination, a fundus examination can also be referred to as ophthalmoscopy. A fundus examination not only provides data about eye health but also gives insights into various conditions, such as hypertension, diabetes, and MS, based on the effects observed in the vessels in the fundus. When these effects are noticed early, the diseases causing these effects can be treated, preventing permanent vision loss.
Premature Retinopathy Can Be Detected
Conducting a fundus examination during infancy is crucial for lifelong advanced eye health. Through a fundus examination done in infancy, conditions such as congenital cataracts and premature retinopathy (ROP) can be identified early, and with the detailed information obtained, the progression of the condition can be halted or permanent vision loss in your child can be prevented.
A fundus examination does not cause any pain and is completely safe, making it possible to conduct it during infancy and childhood. It can be combined with the annual routine eye examination and provides extensive and detailed data in a short amount of time. Especially individuals over the age of 60, who are at a higher risk for conditions such as macular degeneration, should undergo eye examinations as often as recommended by their doctors.
The Importance of the Examination for Early Diagnosis
A fundus examination is crucial not only for the early diagnosis of eye diseases but also for detecting systemic diseases. Changes observed in the fundus vessels can indicate the effects of diseases such as high blood pressure, diabetes, or multiple sclerosis (MS) on the eye. Therefore, it is recommended for not just individuals with visual complaints, but also for anyone as part of a general health screening.
Frequently Asked Questions
How long does a fundus examination take?
A fundus examination typically lasts 15-20 minutes. It may take an average of 20-30 minutes for the drops used to dilate the pupil to take effect. In total, the examination process may take approximately 45 minutes.
What should be considered before a fundus examination?
After the drops used during the examination, vision may temporarily become blurry. Therefore, it is recommended not to drive yourself to the appointment. It is also advisable to wear sunglasses to counter potential light sensitivity.
When should a fundus examination be conducted in premature babies?
The first examination in premature babies is generally conducted within 4-6 weeks, depending on the gestational age and weight. Babies at risk of ROP (premature retinopathy) may need to be monitored at specific intervals.
How often should a fundus examination be conducted?
It is recommended to be conducted once a year in healthy individuals. Those with systemic diseases like diabetes or hypertension, and individuals over the age of 60, may require more frequent check-ups as advised by a doctor.
