Eye Issues and Treatment in Marfan Syndrome, Stickler Syndrome, and Other Related Conditions
44:43-47:17
Astigmatism is again ordinarily no big deal. Somehow I get this quite often. My patient, so they tell me, "Oh, I got this horrible condition called astigmatism." It's just very common condition.
次は乱視です。患者さんが大騒ぎすることも少なくありませんが、乱視もそれほど大きな問題ではなく、非常にありふれた症状です。
And that, by definition, is that when the light go through on up from the left side, the, when they get to the retina, rather than form a very sharp focal point, gets scattered all along the retina. You still can see you just don't see sharply.
乱視とは、入った光が網膜上の1箇所で像を結ぶのではなく、網膜上で拡散してし、複数の像が結ばれてしまう状態です。くっきりとは見えないということです。
This is what it shows. This a big E, right? Rather than the sharp arms legs of the big E and you see this fuzzy shadowy appearance of the big E. It doesn't matter if you, you know, those patients, they complain, they tell you that, "I can see the road sign. I just don't see well. I'm so close to road sign. I still cannot see well. Some of my friends, they really have to get it close to see clearly. When I get very close, I still don't see well." It's because of astigmatism.
この下の画像には、大きな「E」の文字がありますが、ぼやけていてはっきりしません。「道路の標識があるのはわかるけど、はっきりと見えない」とか「ものを近づけすぎるとよく見えない」というのは、乱視によるものです。
That's actually very common. It can be easily corrected with the contact lenses, with the glasses. That's in general population, okay?
乱視は一般に非常によくある症状で、眼鏡やコンタクトレンズで矯正できます。
Marfan patient is a little bit a difficult, simply because dislocated lens. If it just called a corneal astigmatism, easy, easy to do, contact lenses, glasses, the cornea and you probably would hear this from your doctor that.
マルファン症候群の患者さんでは、水晶体亜脱臼があるため多少厄介です。角膜乱視と呼ばれる乱視なら、眼鏡やコンタクトレンズで矯正できます。この言葉は担当医から聞いたことがあるかもしれません。
If you look at the cornea on the left side and that that is a we use it the terminology like a basketball, meaning those two meridians they have equal distance. If rather than being a basketball, now you have a football is oval shape. This meridian is big longer than this one. That's corneal astigmatism. Again, can be easily corrected with the glasses.
左側にある（正常な）角膜の図は、専門的には「バスケットボール状」と呼ばれます。縦の線と横の線の長さが等しいからです。一方の線の長さが他方よりも長い場合には「ラグビーボール状」と呼ばれ、この状態が角膜乱視です。矯正は簡単にできます。
Marfan patients' astigmatism, it's not just caused by cornea. You have this kind of lenticular astigmatism and you can see this light go through this portion, light goes through this portion. That's where you get really confused.
マルファン症候群の乱視の原因は角膜だけとは限りません。水晶体乱視では、図で示したように複数の箇所から光が入り込みますので、複数の像が見えることになります。
At this point even though the lens is still clear, there's no cataract at all. This is, there is indication that you need to remove the lens so you can have those patients see better.
この画像の時点では、水晶体はまだきれいで、白内障もないのですが、視力を矯正するには、水晶体の摘出が必要となることもあります。
