Patchy chorioretinal atrophy, Macular atrophy, Tessellated fundus, diffuse chorioretinal atrophy

Tessellated fundus, Macular atrophy, chorioretinal atrophy, diffuse chorioretinal atrophy

Tessellated fundus, diffuse chorioretinal atrophy, patchy chorioretinal atrophy, Macular atrophy

What is the difference between category 3 macular lesions and category 4?

Category 3 does not have complete loss of choriocapillaris where as category 4 does

Category 4 has much larger lesions that involve the macular compared to category 3

Category 3 and 4 look the same but it depends on what level of myopia the patient has

Category 4 has white lesions whilst category 3 has yellow lesions

Category 2: diffuse chorioretinal atrophy gets its appearance from?

Complete loss of the chroiocapizlaris

Reduced density of pigment in the retinal

Hard exudates from underlying lesions

RPE atrophy

What is NOT a plus lesion?

Staphyloma

Laquer Cracks

Choroidal neovascualrisation

Fuch's spot

A pigmented spot representing scarring phase of myopic CNV is called...

Laquer cracks

WWP

Fuch's spot

Choroidal neovascularisation

Each 1.0D of myopia increases risk of myopic maculopathy by how much?

37%

47%

57%

67%

What is the optometrists role in managing myopic degeneration?

Retard myopia development with atropine, orthoK or other management treatments

Refer to Ophthalmologist

Refer for laser surgery to correct myopia

Educate patient on stem cell treatment

Staphylomas are categorised into 3 types based on the location of the occurrence. What would this image be classified as ?

Narrow, macular

Wide, macular

Peripapillary

Thinning of the sensory retina and rows of irregular shaped yellow patches and is most commonly found inferiorly and infer-temporally. What am I?

WWP

Peripheral drusen

Reticular degeneration

Paving stone degeneration

A bilateral senile pigmentary change is associated with

Peripheral drusen

Snail track

Reticular degeneration

Cystoid degneration

What is a precursor or variant of lattice degeneration?

Snail track

WWP

Paving stone degeneration

Reticular degeneration

What is NOT associated with Retinal detachment?

Lattice degeneration

Snail track

Cystoid degeneration

Peripheral drusen

What is most likely to have adhesion or traction pathology?

Snow flakes

Cystoid degeneration

WWP

Snail track

What is snow flakes commonly seen in (select all that apply)

Retinoschisis

Snail track

Cystoid degneration

Peripheral drusen

What is the difference between typical and Atypical lattice degeneration

Typical lattice has sharp borders with branching lines where as Atypical has fewer white lines and accumulation of snowflakes

Atypical lattice has sharp borders with branching lines where as Typical has fewer white lines and accumulation of snowflakes

Typical lattice is seen more commonly in lower degrees of myopes where as Atypical is only seen in pathological myopia

Atypical lattice is seen more commonly in lower degrees of myopes where as Typical is only seen in pathological myopia

Why should you monitor lattice degeneration closely ?

Can cause vitrial haemorrhages

Can cause secondary glaucoma

Can cause cystoid Mac oedema

Can cause vitreous traction

When does lattice degeneration generally present?

10 years of age

10-20 years of age

20-30 years of age

30-50 years of age
