Hello and thanks for your question. Are you available to chat?
I think you are very well-informed about symptoms of a retinal tear or detachment, it sounds like. I think this can wait until next Tuesday provided your symptoms are stable. What I would look out for if I were, and which would prompt me to be seen quicker than that, is if there is 1) a sudden change in the floaters (ie instead of seeing a handful of them, seeing a giant screen of floaters or several large ones where maybe they were smaller before), 2) flashing or arcing lights (which are different from after images of objects that you've recently viewed; these appear as tiny sparkles or arcs of light that are usually quick and fleeting; if you have these occasionally and intermittently, it should worry you if they become more consistent and persistent, more numerous. If you don't have them at all, then the development of them period should make you nervous. In addition, the development of a curtain, veil, or shade over the vision; or if the vision suddenly worsens significantly and doesn't improve after several minutes.
Does that make sense?
Yes. How frequently do injuries like these result in retinal problems? I understand that I am at increased risk because I am myopic. May I keep wearing contacts - i.e. is a corneal abrasion likely?
I think it's fine to continue to wear the contact lenses, especially if there hasn't been any significant irritation or redness, but yes, occasionally these types of injuries can cause a corneal abrasion (although they usually aren't silent--you'd know by now from the symptoms). As far as the frequency of these types of injuries causing retinal problems--it's difficult to say as there isn't any hard data available about these specific injuries and retinal problems. But in my experience, it is not very common--it usually takes a pretty good thump to the eye with something of more mass and girth to cause a retinal injury.
ok; thanks for your time.
