At a glance
Fundoscopy is an eye examination that lets a doctor look directly at the inside back wall of the eye, called the fundus, which includes the retina (the light-sensitive layer), the optic disc (the point where the optic nerve enters the eye), and the blood vessels that run across them.
The doctor uses a bright light and a special lens to shine through the pupil and view these structures in detail. Because the retina and its blood vessels are visible from the outside without any cutting, the exam reveals signs of disease not only in the eye itself but sometimes in the rest of the body, such as high blood pressure or diabetes.
Medical Condition
Fundoscopy is ordered whenever a doctor needs to assess the health of the retina, optic nerve, or the blood vessels at the back of the eye. It is used both to diagnose new problems and to monitor known conditions over time.
- Diabetic retinopathy: damage to the retinal blood vessels caused by long-term high blood sugar.
- Hypertensive retinopathy: changes in the blood vessels caused by chronically high blood pressure.
- Glaucoma: raised pressure inside the eye that damages the optic nerve.
- Age-related macular degeneration (AMD): deterioration of the central part of the retina that affects sharp, central vision.
- Retinal detachment: when the retina peels away from the back of the eye, causing sudden vision loss.
- Papilloedema: swelling of the optic disc, which can signal raised pressure inside the skull.
- Retinal vein or artery occlusion: a blockage in one of the blood vessels supplying the retina.
- Unexplained vision loss or visual disturbances such as floaters or flashes of light.
- Routine screening in patients with diabetes, hypertension, or a family history of eye disease.
Fundoscopy is a very safe exam, so there are very few situations where it cannot be used. In rare cases, it may be difficult to complete if the patient cannot keep the eye open, has a very small pupil that does not dilate well, or has clouding at the front of the eye such as a dense cataract (a cloudy lens) that blocks the view of the fundus.
Risks & Complications
Fundoscopy is one of the safest examinations in medicine and carries almost no risk on its own. The only notable effects relate to the eye drops used to widen the pupil, which are not always required.
- Temporary blurred vision and light sensitivity for two to four hours after dilating eye drops are used. This clears on its own.
- Difficulty driving after the exam due to blurred near-vision, which is why patients are advised to arrange transport.
- Mild stinging or irritation when dilating drops are applied, lasting only a few seconds.
- Very rarely, dilating drops can trigger an acute angle-closure glaucoma attack in people who already have a narrow drainage angle in their eye. Your doctor will assess this risk beforehand.
- In some patients with certain systemic conditions, the dilating drops can cause a brief rise in heart rate or blood pressure, though this is uncommon.
Preparation & Procedure
Fundoscopy usually requires no fasting, no changes to regular medication, and no special diet. Because the exam itself is non-invasive, the main preparation involves your eyes and your travel arrangements for the day.
If dilating drops will be used, you will be asked not to drive yourself home after the appointment, since near-vision stays blurry for several hours. Wearing contact lenses is usually not possible on the same day as dilation, so glasses are a better choice for the visit. Let the doctor know about any eye drops you already use, any history of eye surgery, any allergy to eye drops, and whether anyone in your family has had glaucoma.
Certain tests or measurements may be taken alongside fundoscopy, depending on what the doctor is looking for.
- Visual acuity test: reading a chart to measure how sharp your vision is.
- Intraocular pressure measurement (tonometry): a quick check of the pressure inside each eye.
- Slit-lamp examination: a microscope examination of the front of the eye before looking at the back.
- Optical coherence tomography (OCT): a scan that produces detailed cross-section images of the retina layers, sometimes arranged on the same visit.
The procedure itself follows a straightforward sequence, though the exact steps and timing depend on whether dilation is used.
- 1. You sit in a darkened room and the doctor checks your general eye health and vision.
- 2. If dilation is planned, one or two types of eye drops are placed in each eye. The drops take roughly fifteen to thirty minutes to widen the pupil fully.
- 3. The doctor dims the room further and asks you to look in different directions while a bright light and lens are held close to your eye.
- 4. In direct fundoscopy, a handheld ophthalmoscope (a small torch-like instrument) is used a few centimetres from your eye. In indirect fundoscopy, the doctor wears a headlamp and holds a wider lens farther away to see a broader area of the retina.
- 5. The doctor examines the optic disc, retinal blood vessels, macula (the central area responsible for sharp vision), and the peripheral retina.
- 6. The exam itself typically lasts five to fifteen minutes. You may see bright spots or colours briefly after the light is removed; this fades quickly.
Aftercare
Fundoscopy requires almost no recovery time. Most people return to their normal activities within a few hours, once the effects of the dilating drops wear off.
- Avoid driving for at least two to four hours after dilating drops are used, or until your near-vision feels normal again.
- Wear sunglasses outdoors immediately after the exam, since dilated pupils let in much more light and bright sunlight can be uncomfortable.
- Avoid reading or close-up screen work until the blurring from dilation settles, usually within a few hours.
- Contact lens wearers should wait until the dilation has fully reversed before putting lenses back in.
- If the doctor found a concerning change, follow-up imaging such as an OCT or a fluorescein angiography (a test where a dye is injected into a vein and photographed as it passes through the retinal vessels) may be arranged.
- Patients with chronic conditions such as diabetes or hypertension are typically scheduled for repeat fundoscopy at regular intervals, as agreed with their eye doctor.
- Report any sudden change in vision, new floaters, flashes of light, or eye pain to a doctor promptly, regardless of when the last fundoscopy was done.
Cost & What Determines It
The price of a fundoscopy appointment varies considerably depending on where it is done, what equipment is used, and whether additional tests are included on the same visit.
- Complexity and reason for referral: a screening exam for a healthy patient is simpler and quicker than a detailed assessment of advanced diabetic retinopathy or a suspected retinal detachment.
- Hospital class and country: a tertiary eye hospital or international hospital in a major city typically charges more than a local clinic, even for the same exam.
- Type of fundoscopy: indirect fundoscopy using wide-field equipment costs more than a basic direct exam with a handheld ophthalmoscope.
- Pupil dilation: if dilating drops are used, these add a small cost and extend the appointment time, which may affect the consultation fee.
- Additional imaging: OCT, fundus photography (a photograph of the back of the eye), or fluorescein angiography are usually billed separately and can add meaningfully to the total.
- Specialist consultation fee: the ophthalmologist's fee varies with seniority, subspecialty expertise, and institution.
- Repeat visits: conditions such as diabetic retinopathy or glaucoma require ongoing monitoring, so the total cost over time is higher than a single visit.
A hospital package for fundoscopy sometimes bundles the consultation, the exam, dilating drops, and a basic report. Fundus photography or OCT imaging is often charged separately. If the exam leads to a follow-up procedure or treatment, those costs are independent.
BPJS Kesehatan and most Indonesian private insurance policies do not cover medical care received abroad. Patients who choose to have fundoscopy overseas usually pay from personal funds or through an international private health insurance plan that explicitly covers outpatient eye examinations abroad. Before travelling, ask the hospital for a detailed written cost estimate that lists every item separately. This protects you from unexpected charges and makes it easier to seek reimbursement if your insurer does cover part of the cost.
Frequently Asked Questions
Does fundoscopy hurt?
Fundoscopy is not painful. Eye drops are used to widen your pupil (the dark circle at the centre of your eye), which may cause a mild stinging sensation for a few seconds, but the examination itself involves only a bright light shone into your eye.
How do I prepare for a fundoscopy?
No fasting is needed before a fundoscopy. Your doctor will put dilating drops into your eyes about 20 to 30 minutes before the exam, so plan to have someone drive you home because your vision will be blurry and your eyes sensitive to light for a few hours afterwards.
How long does a fundoscopy take?
The eye examination itself usually takes 5 to 15 minutes, though the full appointment may be longer because the dilating drops need time to work. You should expect to be at the clinic for about an hour in total.
How much does fundoscopy cost?
The cost depends on whether dilation drops are included, the class of hospital or clinic you choose, and whether the doctor uses a basic handheld instrument or a specialised camera that captures images of the back of your eye. A written estimate from the hospital will give you a reliable figure before you commit to anything.
