Three posters at the American Academy of Optometry meeting in Anaheim in October 2026 carried practical lessons for anyone with retinal disease, or at risk for it: a home test may miss more than people think, a stronger injection can mean fewer visits for one condition, and one type of “eye stroke” can be a warning sign for a brain stroke.
The Amsler grid misses much of the damage
Researchers at the Centre for Eye Health in Sydney compared Amsler grid results with detailed OCT scans in eyes with intermediate or late age-related macular degeneration (AMD). In 42 eyes with an abnormal grid, only about 3% of the area showed problems on both tests. Most damaged areas were abnormal on OCT but looked normal on the grid. The authors think the brain may “fill in” missing spots. The grid still matters for noticing new symptoms, but it cannot replace scans.
Fewer injections for retinal vein occlusion
In the QUASAR trial, aflibercept 8 mg was compared with the standard 2 mg dose for swelling after a retinal vein occlusion (a blocked vein in the retina). Vision gains were similar through 64 weeks, and the higher dose needed about 2 to 3 fewer injections. About 4 in 5 patients on 8 mg had reached intervals of 12 weeks or longer, compared with about two-thirds on 2 mg.
An eye stroke that needs the emergency room
Emily Gibson, OD, described a 71-year-old man with a gray area in his vision caused by blocked branch arteries in the retina. She sent him straight to the emergency department, where scans found severe narrowing of his neck arteries, and he had urgent surgery. She cited a 13.9% rate of stroke after this type of artery occlusion.
What this means for you
- Use the Amsler grid or a door frame to check each eye, but keep scheduled scans too.
- Sudden painless vision loss or a gray curtain in one eye is an emergency. Go to an emergency room or call your eye doctor right away.
- Control blood pressure, diabetes and cholesterol; they affect the eye’s blood vessels as much as the heart’s.

Our office refers retinal disease to retina specialists, but I make sure every patient knows which symptoms mean “go now.”
