What is WWOP?

Retinal white without pressure (WWOP) is a common retinal condition that is reported to occur in up to 30% of the general population.

Is white without pressure serious?

To the inexperienced observer, the area of white without pressure may initially look like a shallow retinal detachment or retinal tear, but WWP does not usually lead to problems and does not require any treatment, although observation is recommended.

What is white without pressure?

White without pressure (WWOP) is a common peripheral retina finding often seen in young patients with myopia. The etiology of WWOP is not well understood. Although WWOP presents no increased risk for RD, it is often mistaken for RD or peripheral retinoschisis.

What is white with pressure and white without pressure?

Okumara[2] coined the term `white with pressure' to describe a flat peripheral detachment without any retinal break. The condition of white without pressure (WWOP) has been described as an advanced form of white with pressure where a certain whitening of peripheral retina is apparent even without scleral indentation.

What disappears with red free filter?

Note its disappearance. Red-free filtering makes some retinal lesions, such as microaneurysms and dot/blot hemorrhages, look dark black and well demarcated. Further, it causes cystoid macular edema to appear as a light gray, fluid filled area in the macula.

What is dark without pressure?

Dark Without Pressure (DWP) lesions are patches of dark retina in central to mid-peripheral retina. Like white without pressure, they are associated with changes at the photoreceptor level and may be a result of vitreoretinal traction but no studies have verified this – literature search reveals only two case series.

What causes thinning retinas?

Rhegmatogenous detachments are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina, pulling the retina away from underlying tissues. The areas where the retina detaches lose their blood supply and stop working, causing you to lose vision.

What is red-free filter?

Answer: The red-free filter excludes red rays from the examination field for easy identification of veins, arteries, and nerve fibers. The red-free filter can be used with any of the six apertures.

Does a choroidal melanoma disappear with red-free filter?

A choroidal nevus is seen superior-temporal to the optic nerve (left). Choroidal lesions disappear or become much lighter with use of the red-free filter as blood vessels appear black against the uniformly dark background caused by the retinal pigment epithelium (right).

What happens if your retina is thin?

Retinal detachment is often accompanied by flashes and floaters in your vision. Retinal detachment describes an emergency situation in which a thin layer of tissue (the retina) at the back of the eye pulls away from its normal position.

What can I do for thin retina?

In those who do develop a retinal tear or detachment, treatment will be performed, typically by a retina specialist. This treatment can range from a laser treatment completed in the office to surgery in the operating room, depending on the severity of the condition.

What disappears with red-free filter?

Note its disappearance. Red-free filtering makes some retinal lesions, such as microaneurysms and dot/blot hemorrhages, look dark black and well demarcated. Further, it causes cystoid macular edema to appear as a light gray, fluid filled area in the macula.

Are optos images inverted?

The Staurenghi lens system is a contact lens that is applied prior to imaging and produces a wide-field inverted image of the ocular fundus. ... Introduced in 2000, the Optos is the first camera capable of producing 200 internal degrees field of view, which equates to about 82.5 percent of the total retinal surface area.

What is the 2020 rule?

The 20-20-20 rule can help your eyes refocus and rest. Look at something 20 feet away, for 20 seconds, every 20 minutes. Rest for 15 minutes. After 2 hours of continuous screen use, rest your eyes for 15 minutes.

Can a thin retina be repaired?

Yes, in many cases an eye doctor can repair a damaged retina. While a patient may not experience completely restored vision, retinal repair can prevent further vision loss and stabilize vision.

What is ora serrata in human eye?

Peripheral Retina The ora serrata is the peripheral termination of the retina and lies approximately 5 mm anterior to the equator of the eye. ... The ora serrata is approximately 2 mm wide and is the site of transition from the complex, multilayered neural retina to the single, nonpigmented layer of ciliary epithelium.

How does an optomap work?

How Does Optomap Work? Optomap is a low-powered scanning laser ophthalmoscope that digitally scans the retina. ... The image can then be filtered, allowing various layers of the retina to be evaluated. The image can be viewed on a computer monitor and stored for future comparisons.
