ICD-10: H35.40

The diagnosis of unspecified peripheral retinal degeneration, classified under ICD-10 code H35.40, involves a combination of clinical evaluation, patient history, and specific diagnostic tests. Here’s a detailed overview of the criteria typically used for this diagnosis.

Clinical Evaluation

Patient History

• Symptoms: Patients may report symptoms such as blurred vision, difficulty seeing in low light, or peripheral vision loss. A thorough history of visual changes is essential.
• Medical History: A review of the patient's medical history, including any previous eye conditions, systemic diseases (like diabetes), or family history of retinal diseases, is crucial.

Physical Examination

• Visual Acuity Testing: Initial assessments often include standard visual acuity tests to determine the extent of vision impairment.
• Fundoscopic Examination: An ophthalmologist will perform a dilated fundoscopic exam to visualize the retina and assess for any signs of degeneration or other abnormalities.

Diagnostic Tests

Imaging Techniques

• Fundus Photography: This technique captures detailed images of the retina, allowing for the identification of degenerative changes.
• Fluorescein Angiography: This test involves injecting a dye into the bloodstream to highlight blood vessels in the retina, helping to identify areas of degeneration or leakage.
• Optical Coherence Tomography (OCT): OCT provides cross-sectional images of the retina, allowing for detailed assessment of retinal layers and any structural changes associated with degeneration.

Electroretinography (ERG)

• ERG Testing: This test measures the electrical responses of the retina's light-sensitive cells (rods and cones) to light stimuli. Abnormal results can indicate retinal dysfunction, supporting a diagnosis of degeneration.

Differential Diagnosis

• It is essential to rule out other retinal conditions that may present similarly, such as diabetic retinopathy, retinal detachment, or other forms of retinal degeneration. This may involve additional imaging or testing.
