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
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
