5. White WITH pressure is NOT associated with an INCREASED risk of retinal breaks

True

False

White with pressure refers to a phenomenon known as vitreous opacities, where small white floaters appear in the field of vision due to the vitreous gel in the eye becoming more liquefied. While this condition can be concerning, it is not associated with an increased risk of retinal breaks. Retinal breaks are typically caused by other factors such as trauma, aging, or certain eye conditions. Therefore, the statement that white with pressure is not associated with an increased risk of retinal breaks is true.

6. White WITHOUT pressure is NOT associated with an INCREASED risk of retinal breaks

True

False

White WITHOUT pressure refers to the absence of any external force or pressure on the eye. Retinal breaks are typically caused by trauma or pressure on the eye, so if there is no pressure, there is no increased risk of retinal breaks. Therefore, the statement is true.

7. Primary degenerative acquired retinoschisis arises from

Coalescence of cysts of peripheral cystoid degeneration

Coalescence of cysts of peripheral chorioretinal atrophy

Coalescence of cysts of peripheral reticular degen

Coalescence of cysts of peripheral white with/without pressure

8. What % of retinoschisis will contain AT LEAST 1 retinal break?

20%

25%

30%

35%

The correct answer is 25%. This means that out of all cases of retinoschisis, 25% will have at least one retinal break. Retinoschisis is a condition where the retina separates into two layers. A retinal break refers to a tear or hole in the retina. This suggests that a significant proportion of retinoschisis cases will have some form of retinal break, highlighting the potential complications and severity of the condition.

11. What is true of Asymptomatic flap tears? (SELECT 2)

Asymptomatic Flap Tears have a 40% chance of progressing to RRD if a localized RD is present

Asymptomatic Flap Tears have a 10% chance of progressing to RRD if a localized RD is present

Asymptomatic Flap Tears have a 40% chance of progressing to RRD if a localized RD is NOT present

Asymptomatic Flap Tears have a 10% chance of progressing to RRD if a localized RD is NOT present

Asymptomatic Flap Tears have a 40% chance of progressing to RRD if a localized RD is present. This means that if there is a localized retinal detachment (RD) in addition to the flap tear, there is a higher likelihood of the tear progressing to rhegmatogenous retinal detachment (RRD). On the other hand, Asymptomatic Flap Tears have a lower chance of progressing to RRD if a localized RD is not present, with only a 10% chance. This suggests that the presence of a localized RD increases the risk of progression to RRD in cases of Asymptomatic Flap Tears.
