What are the fundus changes in a hypertensive patient?
Hypertensive retinopathy causes vascular constriction of retinal arterioles and typical fundus findings, such as blot hemorrhages, hard exudates and cotton wool spots resulting from ischemia within the nerve fiber layer.
What is grade 2 hypertensive retinopathy?
Grade 2: High blood pressure and narrowing of the arteries is more pronounced. Generally no symptoms are present. Grade 3: Signs of damage such as retinal haemorrhage (bleeding) and cotton wool spots, i.e. white patches on the retina, are present upon inspection.
What is a common Fundoscopic change associated with HTN?
Hypertensive retinopathy is retinal vascular damage caused by hypertension. Signs usually develop late in the disease. Funduscopic examination shows arteriolar constriction, arteriovenous nicking, vascular wall changes, flame-shaped hemorrhages, cotton-wool spots, yellow hard exudates, and optic disk edema.
Why is a fundus test done in hypertension?
In addition, hypertension may accelerate nonvascular eye disease, including age-related macular degeneration and glaucoma. Fundoscopy should be part of the physical examination on every patient with newly diagnosed hypertension since the retina is the only part of the vasculature that can be visualized noninvasively.
What are the grades of hypertensive retinopathy?
Grade 1: Barely detectable arterial narrowing. Grade 2: Obvious arterial narrowing with focal irregularities (Figure 1) Grade 3: Grade 2 plus retinal hemorrhages, exudates, cotton wool spots, or retinal edema (Figure 3) Grade 4: Grade 3 plus papilledema (Figure 4)
What is drusen?
Drusen are small, yellowish deposits of cellular debris that accumulate under the retina — the light-sensitive layer of cells at the back of the eye that’s essential to vision. Drusen occur in most people over age 60 and are more common in women than men.
What is silver wiring?
Abnormal reflections of light seen on the ophthalmoscopic examination of the retina of persons with long-standing, uncontrolled hypertension. See also: wiring.
How is fundus test done?
obtain a better view of the fundus of eye. Dilated fundus examination or dilated-pupil fundus examination (DFE) is a diagnostic procedure that employs the use of mydriatic eye drops (such as tropicamide) to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye.
How do you code hypertensive retinopathy?
ICD-10 Diagnosis Codes:
- H35.031–Hypertensive retinopathy, right eye.
- H35.032–Hypertensive retinopathy, left eye.
- H35.033–Hypertensive retinopathy, bilateral.

What is PPA in ophthalmology?
Peripapillary atrophy (PPA) is a clinical finding associated with chorioretinal thinning and disruption of the retinal pigment epithelium (RPE) in the area surrounding the optic disc. It is non-specific and can occur in both benign and pathologic conditions, including glaucoma 1 and high myopia 2.
