What is Microcystoid degeneration?
Microcystoid degeneration consists of small vesicles set in an area of greyish white retina near the ora serrata. It is present in all eyes and, although it increases in extent with age, it is not directly responsible for break formation.
What causes peripheral retinal degeneration?
Extreme nearsightedness (myopia) Previous eye surgery, such as cataract removal. Previous severe eye injury. Previous other eye disease or disorder, including retinoschisis, uveitis or thinning of the peripheral retina (lattice degeneration)
What is peripheral cystoid degeneration?
Definition. Degenerative changes of the peripheral retina consisting of close-packed tiny cystic spaces at the outer plexiform/inner nuclear retinal level. The degeneration is very common in adult eyes and starts adjacent to the ora serrata and extends circumferentially and posteriorly. [ from HPO]
What causes white without pressure?
WWOP may be circumferential and usually occurs bilaterally. WWOP usually is associated with vitreous degeneration and posterior vitreous detachment (PVD). Horseshoe retinal tears or linear retinal tears can develop along the posterior border of WWOP, and these tears are associated with the traction of PVD.
What is snail track degeneration?
Snail-track degeneration is a morphologic descriptive term for retinal lesions with the same characteristic size, shape, orientation, and location as lattice lesions and is associated with the aforementioned yellowish flecks.
What is Chorioretinal degeneration?
Chorioretinal heredo-degeneration is defined as a. hereditary, primary, progressive degeneration. affecting the normally developed choroid and. retina.
What causes flashing light in corner of eye?
Vitreous humor is a gel-like substance that fills the majority of your eyeball. This gel allows light to enter the eye via the lens, and it is connected to the retina. If vitreous gel bumps or pulls on the retina, you may see flashes of light in the corner of your eye.
What is peripheral retina?
Aug. 31, 2017. The area of the retina outside the macula. The peripheral retina gives us our side (peripheral) vision and night vision.
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 is the snail trail?
First let’s break down what a snail trail is. This trail of hair spans the area from your pubic hair up to your belly button in a thin line. A good pair of high waisted jeans and you can forget the hair is even there. You might want to check out our guide on trimming your pubic hair before tackling your snail trail.
What is a snail trail in the eyes?
This area of white is on the retina in the far periphery. It can only be seen when the eye is dilated. This occurs often as an inherited trait in near-sighted people. People that have this are more susceptible to developing retinal holes and detachments.
What are Chorioretinal lesions?
In summary, chorioretinal lesions were found not to be uncommon among patients with CGD. The lesions included RPE atrophy or pigment clumping and are similar to previous descriptions. We also found ischemia of the peripheral retina, neovascularization, and macular edema, which had not been previously reported.
