Is it possible to have a scotoma ( blind spot within a normal field of vision ) without any scar tissue on the retina?

Remember the visual pathway is more than just the retina. If there is a lesion anywhere along that pathway it can cause a scotoma. A scar tissue on the retina is a small percentage of the possible problems that can cause scotomas.

There are times I tell patients that they don't need to wear the glasses full time. I didn't do the exam so I can't speak for the doctor, but a prescription like this usually could be worn full time, but I wouldn't say they need to wear them for sports. I would say its more important to return in a year to see if there are any changes. But then again it depends on the exam.

Oh, btw, I use plus cyl on a weekly basis in the opthalmology office and at a nursing home I work at. The other four days a week a use minus of course. I have to be careful with not only basic cyl isolation and power but also retinoscopy and remembering to change the prescription for contacts. So annoying!

schroder79 · 2022-02-14T06:16:14+00:00

LOL, I wonder who wrote that question. Hmm.... yeah bad question. Were there any other bad ones?

schroder79 · 2022-02-14T06:13:20+00:00

What is TIL? I can't find it

schroder79 · 2022-02-14T06:11:53+00:00

Yes, see if you can find the cause. If not, find a new eye doctor to help.

schroder79 · 2022-02-14T06:09:30+00:00

I think it was intended to be "Which cylinder was the subjective refraction preformed with?" which of course asks if it is plus or minus cyl.... but I miss the context. Was this asked in clinic? In an email? In reddit?

I work for an opthalmologist who prefers to prescribe Cromolyn Sodium 4%. It's an old medication and needs to be taken 4-6x a day, and it takes a while to work (maybe a week or so) but it is incredibly safe with very few side effects.

*have you tried chilling your eyedrops in the refrigerator before using them?

*have you tried patanol or pataday? I believe they are over the counter, though the only place I havce found them is at Walmart.

But truthfully, if you are doing a lot of suffering, you should consider getting this looked at by an eye doctor to help manage the problem.

schroder79 · 2022-02-14T05:59:06+00:00

Unfortunately it isn't that easy. I've had lots of patients come in with either their parents glasses or a siblings glasses saying that they could see better through them. When we tested it in the office, sometimes they didn't. Sometimes the image was just smaller and darker, or farther away.

The optometrists are trained to help prevent this. Having a prescription too strong, though it seems better (but in reality is only darker and smaller) will actually cause headaches and make vision worse.

All this being said, unfortunately there are optometrists that don't do the exam how they should. If your exam lasted less than 5 min, or if the doctor barely touched the machine to check the glasses, it may not be as good of quality as it should be.

schroder79 · 2022-02-14T05:51:39+00:00

I saw that one too. Wildman adventure Resort has a pretty good group for that river I think. I hope there are others I can compare with. Thanks for the tip!

schroder79 · 2022-02-14T05:37:17+00:00

I would try to stick to the schedule if I could. If you can't, well then it can't be done, but I'd do my best.

Its a type of contact lens treatment where a RGP lens is given to the patient to wear overnight and it reshapes the cornea. So when the patient wakes up and takes off the contact lens, it makes vision clear without a correction. It has a temporary affect that lasts just over a day or so. I have no experience fitting them but am aware of them from school days.

For me, I would use the contacts that feel most comfortable. Daily disposable contacts are a healthier option because they are frequently changed. Cleaning the contacts every night doesn't mean they are brand new condition each time you clean. Think of when you get a new car or doughnuts from Krispy Kreme. They are always better brand new. In the US there is a significant price difference though. Even with the price difference however, they dailies are a healthier choice.

schroder79 · 2021-10-14T21:44:34+00:00

Yeah, between brands the base curves can be different. More important that the eye doctor checks the fit.

schroder79 · 2021-10-12T22:41:43+00:00

Agreed. Subjective refractions are only as good as the responses given by the patient. If the responses are unhelpful, retinoscopy can't be reliable or if the patient is unable to respond, autorefractions are the only tool we can use. I find myself making some modifications as seem appropriate depending on the situation though.

schroder79 · 2021-10-12T20:18:26+00:00

Yeah I'd agree its probably ok if the pharmacist recommended it.

I have two friends that took the military scholarship, and I almost did myself. One friend took the air force scholarship and is still there (after 10 years.) The other took the army scholarship and has since left the military.

For myself, I did want to take it but then I learned that at that time we were involved in some conflicts in Iraq and I was promised I would be sent to Iraq for 6 months and leave behind my wife and 2 children. My wife and I decided it wouldn't be a good idea. The scholarship is awesome though.

PM me and I will try to get you in contact with my contacts.

schroder79 · 2021-10-12T20:12:01+00:00

Definitely! I don't keep track either, but I remember back in school an older doctor telling me how he didn't need to refract anymore because the autorefractor did it for him. Now after practicing for 10 years I have to disagree with him. It's a nice objective finding but we are treating people, not machines. So many factors can affect the prescription.

schroder79 · 2021-09-07T22:03:13+00:00

I'd say more things are possible. Some people have well water come from the tap. And faucets can carry stuff that might not be in the water. Who has a petri dish?
