Oftalmoskop<\/strong>, g\u00f6z doktorlar\u0131n\u0131n g\u00f6z\u00fcn i\u00e7ini yani, g\u00f6z k\u00fcresinin, funduz (g\u00f6z dibi) denilen i\u00e7 k\u0131sm\u0131n\u0131 muayene etmek\u00a0 i\u00e7in kullan\u0131lan bir alettir. 1850\u2019de Van Helmholtz taraf\u0131ndan geli\u015ftirilen oftalmoskop, bug\u00fcn her pratisyen hekimin kulland\u0131\u011f\u0131 \u00e7ok \u00f6nemli bir alettir.
\nOftalmoskop, bir \u0131\u015f\u0131k kayna\u011f\u0131, merkezinde deli\u011fi olan bir i\u00e7b\u00fckey k\u00fcresel ayna ve \u00e7e\u015fitli merceklerden meydana gelir. Bu mercekler, aynan\u0131n merkezindeki deli\u011fe uyarlar ve d\u00f6nen bir diskin etraf\u0131na yerle\u015ftirilmi\u015flerdir, kolayca \u00e7evrilebilirler.<\/p>\n

I\u015f\u0131k kayna\u011f\u0131 kendinden olan modern oftalmoskoplar, g\u00f6z dibinde geni\u015f bir ayd\u0131nlatma ve g\u00f6zleme sahas\u0131 sa\u011flarlar. Elektrik oftalmoskoplardan \u00f6nce, yans\u0131tmal\u0131 oftalmoskoplar kullan\u0131lmaktayd\u0131. Bu metodda, hastan\u0131n ba\u015f\u0131n\u0131n arkas\u0131ndaki \u0131\u015f\u0131k kayna\u011f\u0131ndan gelen \u0131\u015f\u0131k, a\u00e7\u0131l\u0131 bir ayna vas\u0131tas\u0131yla g\u00f6zbebe\u011fine yans\u0131t\u0131larak g\u00f6z dibi incelenmekteydi. Mevcut oftalmoskoplar\u0131n birbirine yard\u0131mc\u0131 olan iki \u00e7e\u015fidi vard\u0131r: Direkt ve indirekt oftalmoskop.<\/p>\n

Direkt oftalmoskoplar:<\/strong> Hastan\u0131n g\u00f6z\u00fcne ait \u0131\u015f\u0131\u011f\u0131 k\u0131r\u0131c\u0131, ortamlar\u0131 b\u00fcy\u00fct\u00fcc\u00fc bir sistem olarak kullan\u0131l\u0131rlar. Muayene edenin ve hastan\u0131n g\u00f6z\u00fcnde k\u0131rma kusuru yoksa k\u00fc\u00e7\u00fck, d\u00fcz, 15 misli b\u00fcy\u00fck bir g\u00f6r\u00fcnt\u00fc elde edilir. Hipermetrop bir g\u00f6z, daha geni\u015f bir sahay\u0131 daha az bir b\u00fcy\u00fctme ile g\u00f6r\u00fcr. Miyop g\u00f6z ise, daha k\u00fc\u00e7\u00fck bir sahay\u0131 daha fazla bir b\u00fcy\u00fctme ile g\u00f6rebilir. Muayene eden kimse, hastan\u0131n g\u00f6zbebe\u011fine yakla\u015ft\u0131k\u00e7a g\u00f6zdibinde g\u00f6r\u00fclen saha artar. Bu, bir anahtar deli\u011finden bakmaktaki duruma benzer. Hasta ve muayene edenin g\u00f6z\u00fcnde bulunan orta derecedeki hipermetropi ve miyopiler, oftalmoskoptaki lensler (mercekler) vas\u0131tas\u0131yla telaf\u00ee edilebilir. Pilli ve \u015farjl\u0131 el oftalmoskoplar\u0131 mevcuttur. Tekrar doldurulabilen nikel-kadmiyum pilleri daha iyi ve parlak bir ayd\u0131nlatma sa\u011flamaktad\u0131r.<\/p>\n

\u0130ndirekt oftalmoskoplar:<\/strong> Bunlarda +13 ile +30 diyoptrilik konveks bir mercek kullan\u0131l\u0131r. Bu mercek, hastan\u0131n g\u00f6z\u00fcn\u00fcn 3-5 cm \u00f6n\u00fcnde tutulup, g\u00f6z\u00fcn i\u00e7 k\u0131sm\u0131ndan yans\u0131yan \u0131\u015f\u0131nlar\u0131 mercek ve muayene eden g\u00f6z aras\u0131nda, ger\u00e7ek ve ters bir hayal elde etmek \u00fczere odaklamaya yarar. \u0130ndirekt oftalmoskopi i\u00e7in daha \u015fiddetli bir \u0131\u015f\u0131k kayna\u011f\u0131na ihtiya\u00e7 vard\u0131r. Ba\u015fa monte edilebilen y\u00fcksek \u0131\u015f\u0131k kayna\u011f\u0131n\u0131n geli\u015ftirilmesi, bu tekni\u011fe \u00e7ok faydal\u0131 olmu\u015ftur. Yeni geli\u015ftirilen binok\u00fcler indirekt oftalmoskoplar sayesinde, ayn\u0131 ki\u015fiyi iki ki\u015finin g\u00f6zlemesi ve ayn\u0131 anda bakmalar\u0131 m\u00fcmk\u00fcn olmaktad\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
