What is Valsalva retinopathy?

Valsalva retinopathy is a preretinal hemorrhage caused by a sudden increase in intrathoracic or intraabdominal pressure. It was first described by Duane in 1972. It usually occurs in an otherwise healthy eye and spontaneously resolves.

What is sickle cell retinopathy?

Sickle cell retinopathy is an ocular manifestation of the spectrum of sickle cell disease, an inherited group of hemoglobinopathies with numerous systemic and ocular presentations. Hemoglobin is an iron containing protein in red blood cells that transports oxygen.

How do you treat commotio retina?

There is no treatment for commotio retinae. However, most people fully recover in 3 to 4 weeks. In cases where trauma causes more severe damage, you may recover only part of your eyesight. Talk to your doctor about your chances of making a full recovery.

What is hypertensive retinopathy?

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.

Can Valsalva cause retinal detachment?

This unique case shows that the Valsalva manoeuvre can cause an acute retinal detachment in patients with congenital optic disc cavitations.

Why do Sicklers have yellow eyes?

Jaundice is a common early symptom of sickle cell disease (SCD). It happens when sickled red blood cells die faster than the liver can filter them out. Free hemoglobin, a protein in red blood cells that carries oxygen throughout the body, gets converted to a pigment that collects and turns the skin and eyes yellow.

How long can a person live with sickle cell disease?

With a national median life expectancy of 42–47 years, people with sickle cell disease (SCD) face many challenges, including severe pain episodes, stroke, and organ damage.

How long does it take for commotio retina to resolve?

Most cases resolve within 4 weeks of injury although some improvement can continue for up to 6 months. However, some patients can have permanent macular damage with absolute or relative scotoma.

What is angle recession glaucoma?

Angle recession glaucoma (ARG) is a secondary open angle glaucoma that is associated with ocular trauma. Recession of the anterior chamber angle is a common slit lamp and gonioscopic finding following concussive ocular trauma.

Can hypertensive retinopathy be reversed?

Q: Can hypertensive retinopathy be reversed? A: It depends on the extent of damage to the retina. In many cases, the damage caused by hypertensive retinopathy can slowly heal if the necessary steps to lower one’s blood pressure are taken.

What are the symptoms of hypertensive retinopathy?

Symptoms of hypertensive retinopathy

reduced vision.
eye swelling.
bursting of a blood vessel.
double vision accompanied by headaches.

What are the signs and symptoms of Purtscher’s retinopathy?

Background: Purtscher’s retinopathy (a.k.a. angiopathia retinae traumatica) is a traumatic angiopathy, most commonly caused by head and chest trauma. The most-prevalent bilateral retinal signs include white ischemic infarcts (cotton-wool spots or Purtscher-flecken) and hemorrhages (dot and blot, pre-retinal, or flame).

What causes Purtscher’s retinopathy after acute pancreatitis?

A clinical appearance of the fundus identical to Purtscher’s retinopathy may be seen after acute pancreatitis. The retinopathy is probably caused by retinal vascular occlusion secondary to fat embolism or to thrombosis.

What are purpurtscher Flecken?

Purtscher flecken are pathognomonic findings and can be described as polygonal areas of retinal whitening with a clear demarcating line (within 50µm) between the affected retina and contiguous normal retinal vessels.

What is the prognosis of opoct in retinopathy?

OCT displays hyperreflectivity of the inner retinal layers due to inner retinal edema. Prognosis is variable and largely depends on the extent of retinal involvement. Purtscher retinopathy is the appearance of cotton wool spots, hemorrhages, and retinal edema located predominantly around the optic disc.
