斜位矯正

新年、明けましておめでとうございます。 今年の年賀は年内に書くことが出来ず、いただいた分から返信させていただいています。  失礼の段、お許しください。(店頭のお客様用の2000枚は年内に発送したのですが・・・)

さて、今日は昨年末に斜位矯正をして非常に喜ばれた例をご紹介します。

斜位矯正

一般には、メガネは視力を補正する道具だと思われていますが、それだけではありません。
年末に相談に見えた中年男性は、数十年来複視(二重像)に悩まされ、これまでにあらゆる医療機関やメガネ店にかかったが 問題は解決せず、諦めており、運転免許はもとより、職業さえ制限を余儀なくされていました。

私が検眼してみますと、かなり深刻な斜位、というより斜視と言った方が良いほどの眼位の異常がありました。 しかも、ずれは上下方向と水平方向にまたがり、それらをベクトル的に合成して矯正に要したプリズムは片方で5pd(プリズムディオプトリー(1mにつき、 5cmのずれ))に達していました。
プリズム矯正の実用的限界に近い度数でしたが、この方の二重像は直ちに解消し、感激していただいた次第です。

この方の例は極端ですが、明確な自覚につながらない場合でも、斜位を持つ方は多く、未熟な検査の網をくぐっているはずです。 遠視も誤解されているものの代表で、これも「メガネは視力を補正するもの」という短絡的な認識からは到底理解が及ばないようです。 とくに若年者ほど遠視は自覚されにくく、本人が納得しない場合は、症状が顕在化するまで放っておくしかありません。  ただ、正視眼の人が3時間集中できる近業が2時間、あるいは1時間でダウンすることも起こりうる訳で、ある意味では人の一生をも左右しかねない 問題なのですが。
視機能の発達途上の幼児の強度の遠視を放置すると、調節と輻輳のアンバランスから斜視になり、複視を回避するために 脳が効き目でない方の眼の情報を遮断するので、その眼は廃用性の弱視になり、成長後にレンズでの矯正を試みても視力が補正できなくなるのです。
年末に見えた方は、矯正視力が左右共0.3くらいあり、完全に弱視化していなかったので、成長期後に発症したものと思われますが、  逆に片方の眼(効き目でない方)が弱視化していなかっただけに、そのつらさも相当なものだったと思われます。

Gon

ウチの愛猫”ゴン”です。家内が独身時代から飼っていた猫で、17歳を越えます。
ゴンを題材にして娘のスピーチコンテストの原稿を書いてみました。

Gon, my cat is more a member of our family than just a pet. We have lived together for as long as I can remember. When I was a little girl, she was not only a good friend but also an older sister to me because I am an only child.

I don’t know when our roles changed exactly but she has come to love and rely on me, just as if I were her mother, even though she’s four years older than I. Every time I come home from school, she comes to greet me from wherever she was sleeping in the house. She doesn’t want anything from me, except to be picked up and scratched on the back while cuddling her on my lap.

Though she can’t speak, she can express herself and I can always understand her feelings by the way she meows. Especially when she is “purrfectly” happy and content.

She’s 17 cat years old, which is the equivalent to 80 or more human years. She’s not as fast as she used to be, but she’s still very agile. She can jump up on the chair next to mine when she wants to be petted. Now just imagine an 80-year-old woman jumping as high as her own height, that’s a pretty amazing thing to do, don’t you think?

When I study late into the night or when I’m sick she watches me and never leaves my side.

This is why she is so special to me. What an amazing creature!

You’re probably wondering why “she” is called” Gon”. Well, my mother was still living with her family, when one day one of her piano students gave her the cutest little kitten. My mom’s younger sister mischievously named her”Gonzaemon” which happens to be an old fashion name for a male cat in Japan, and since then she’s been known as “Gon”! Gon gave birth to several kittens, and my mother chose the most handsome kitten and named him”Leo” and gave the rest away.

Soon after that my mom decided to marry my dad and she thought it would be too much to ask him if she could bring two cats with her into their new home. So she decided to leave Gon and her son with her parents in Shimane Prefecture.

However after a few months, she told my dad how much she missed her cats and how worried she was about them because her parents really didn’t like animals all that much. My dad immediately understood her feelings and they drove 5 hours one way just to pick up the cats!

Leo was no longer there but Gon was and my mother remembers that it was like she had been waiting for her to come back to take her home.

Her new life with my parents was about to be disrupted again, though. A little more than a year after she came to live with them, my parents were expecting me. Just a few months before I was born my mom became very anxious about whether or not a cat was a good thing to have around a new baby so Gon was sent to live with my aunt.

Gon finally came back to live with us after I became a year old. We haven’t been separated since then and never will be again. I still feel a bit guilty for what she went through because of me and I intend to stay by her side and make her last years, her best years.
