CRAO 1 Juli

What are believed to be the earliest changes in eyes with mild acute CRAO?

• Opacification of the inner retinal layers

• Loss of retinal layer stratification

• Opacification of the middle retinal layers

• Thickening of the outer plexiform layer

What is predominantly affected by the central retinal artery hypo perfusion during CRAO?

• Ganglion cell layer

• Outer nuclear layer

• Deep capillary plexus

• External limiting membrane

According to the paragraph, what happens as the severity of CRAO increases?

• Retinal layer stratification is preserved

• Opacification primarily affects the outer retina

• Inner retinal layers become involved

• Cell body death does not occur

How does the current study suggest adjusting the OCT classification of acute CRAO?

• Based on outer, middle, and inner retinal layers

• According to the extent of retinal thickening

• Into incomplete, subtotal, and total varieties

• To mild, moderate, and severe grades

What was the starting point for measuring the time interval categories for OCT scan classification?

• The date of the patient's birth

• The date of the patient's first clinic visit

• The symptom onset date (Day 0)

• The date of the first OCT scan

For the study patients, what was evaluated in follow-up OCT scans?

• New ocular conditions

• The same set of features as the initial scans

• Visual acuity changes

• Retinal vessel changes

Which feature is NOT listed as an OCT finding in the study?

• Inner limiting membrane detachment (ILMD)

• Hyperreflective foci

• Hyporeflective fluid-filled cavities

• Retinal vessel occlusion

What is the duration of symptoms for acute CRAO cases studied in this research?

• Less than 3 days

• Less than 7 days

• Less than 14 days

• Less than 30 days

Over what period does this study examine OCT changes in acute CRAO cases?

• 7 days

• 14 days

• 21 days

• 30 days

What method was used to determine the presence of a patent cilioretinal artery?

• Spectralis HRA OCT scan

• Colour fundus photographs

• Snellen's visual acuity test

• Inner retinal layer features
