Worksheet time: 5mins
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?
