Snellen chart

I'm trying to walk with him through the school area, and we've got stairs and all of this stuff.

And, um, I get into the room and I look at the medical doctor and he had the Snellen eye chart up there.

And I was like, "I- he needs glasses." And [chuckles] he looks at me and talks to the kid, and they speak back and forth, and he just looks at me and he's like, "He's blind.

Not gonna...

I think what we really found interesting with this patient was that these changes remain detectable, you know, over a year later, even after the patient's high contrast visual acuity had recovered to 2020.

You know, clinically, many of our patients with lacquer cracks will tell us that they still experience a persistent scotoma or subjective visual disturbance despite the high contrast Snellen acuity recovering.

And Really, our visible light OCT findings provide a potential structural correlate for those symptoms.

In other words, an eye may recover enough to read the 20-20 line, but the subtle photoreceptor and RPA abnormalities can persist long after the acute hemorrhage has resolved.

Um, and where somebody is now and what the rate of change has been are often useful for me and I guess in some circumstances, um, for you as well.

And then one of the reactions about will it get any better- Uh, it may be that the, the, you know, the bare facts, the Snellen chart result or the visual field result, or in my case, the scan results may not get any better.

Um, but people's adaptation has an endless possibility to get better.

And so there is always the possibility that somebody will cope better with what's going on, uh, even if, um, their, their sight doesn't necessarily improve.

And there are certain tests we can do.

Sometimes someone might be seeing relatively well and in a high contrast, like eye chart test, we call Snellen visual acuity.

So I may still have very good Snellen visual acuity, meaning they can read the lines on the chart, but reading the lines on the chart is not real world.

Real world is like we said, You might be driving in the fog or driving at nighttime or reading in low light conditions.

So there's there's this test called a glare test where actually shine a bright light at you and say, OK, how much does your vision actually degrade? And so we can go by those to actually say, is this going to be covered by insurance? But honestly, there's a couple of checkpoints I think are really important.
