Dilated macular or fundus exam performed, including documentation of the presence or absence of macular edema and level of severity of retinopathy (EC)
CPT4 code
Name of the Procedure:
Dilated Macular or Fundus Exam
Common Names: Dilated Eye Exam, Fundus Exam, Retinal Exam
Summary
A dilated macular or fundus exam is an eye examination where special drops are used to widen the pupil, allowing the eye doctor to see the back of the eye, particularly the retina and macula. This helps in detecting and documenting the presence or absence of macular edema and evaluating the severity of retinopathy.
Purpose
The primary goal is to assess the health of the retina and macula, which are vital for vision. This exam is important for diagnosing conditions such as diabetic retinopathy, macular edema, and other retinal disorders. Detecting these conditions early can help in managing and preventing vision loss.
Indications
- Symptoms like blurry vision, spots, or flashes of light.
- History of diabetes, high blood pressure, or other health conditions that can affect the eyes.
- Regular monitoring for patients with known retinal conditions.
Preparation
- Patients may be instructed to bring sunglasses, as their vision will be sensitive to light after the dilation.
- No special fasting or medication adjustments are usually required.
- Inform the doctor of any current medications or allergies.
Procedure Description
- The patient sits in a chair, and the doctor administers eye drops to dilate the pupils.
- It takes about 15-30 minutes for the drops to take full effect.
- Once dilated, the doctor examines the retina and macula using an ophthalmoscope or a slit-lamp microscope with a special lens.
- The doctor documents the findings, including the presence or absence of macular edema and the severity of any retinopathy.
Duration
The entire procedure typically takes between 30 minutes to an hour, including the time for pupil dilation.
Setting
This exam is usually performed in an ophthalmologist's office or an outpatient clinic.
Personnel
- Ophthalmologist or Optometrist
- Ophthalmic Technician or Assistant
Risks and Complications
- Temporary blurred vision.
- Light sensitivity for several hours post-exam.
- Rarely, allergic reactions to the dilation drops or increased intraocular pressure.
Benefits
The exam allows early detection of eye conditions, which can prevent or limit vision loss with timely treatment.
Recovery
- Patients may need to avoid driving for a few hours until their vision returns to normal.
- Wearing sunglasses will help manage light sensitivity.
- Follow-up appointments may be necessary based on the findings.
Alternatives
- Photos of the retina (fundus photography).
- Optical coherence tomography (OCT) for detailed images of the retina. Each alternative has its benefits, such as being non-invasive, but may not provide as comprehensive a view as a dilated exam.
Patient Experience
During the procedure, patients might feel mild stinging when the dilation drops are applied. After the exam, vision may be blurry or sensitive to light for a while, but this usually resolves within a few hours. Comfortable seating and instructions on what to expect can help manage any discomfort. Pain is generally minimal and well-tolerated.
