Pahimetria cornean\u0103<\/h2>\n

 <\/p>\n

Ce este pahimetria cornean\u0103?<\/h2>\n

Pahimetria cornean\u0103 este un examen care m\u0103soar\u0103 grosimea corneei. Cunoa\u0219terea grosimii corneei este utilizat\u0103 pentru a defini fiabilitatea de m\u0103surare a presiunii intraoculare. Examinarea este de asemenea realizat\u0103 ca un instrument pentru evaluarea diferitelor patologii ale corneei, cum ar fi keratoconus, edemul cornean \u0219i \u00een diagnosticarea glaucomului.<\/p>\n

Exist\u0103 diferite tehnici de investigare: tomografie cu camer\u0103 de tip Scheimpflug a corneei (pahimetria optic\u0103) ofer\u0103 o hart\u0103 a pahimetric\u0103 a corneei sau o sond\u0103 cu ultrasunete (pahimetria acustic\u0103). \u00cen primul caz, pute\u021bi avea o hart\u0103 care arat\u0103 o grosime a pahimetriei corneei la fiecare punct \u0219i v\u0103 permite s\u0103 identifica\u021bi loca\u021bia \u0219i valoarea celui mai sub\u021bire punct.<\/p>\n

Care este scopul pahimetriei corneei?<\/h2>\n

Testul serve\u0219te pentru a m\u0103sura grosimea corneei, cristalinul natural care \u00eent\u00e2lne\u0219te primul lumina \u00een calea sa \u00een interiorul ochiului.<\/p>\n

Standardele de preg\u0103tire<\/h2>\n

Nu exist\u0103 reguli specifice de preg\u0103tire. Pentru examinarea efectuat\u0103 cu pahimetrie, este nevoie de ultrasunete. \u00cenainte de examinare, sunt aplicate pic\u0103turi estetice pentru ochi pentru c\u00e2teva momente folosind o sond\u0103 similar\u0103 cu un pix mic. Pentru procedura de pahimetrie, pic\u0103turile estetice pentru ochi sunt op\u021bionale (vezi procesul de tomografie a corneei).<\/p>\n

Care pacien\u0163ii se pot supune examin\u0103rii?<\/h2>\n

Examinarea poate fi efectuat\u0103 de c\u0103tre pacien\u021bi de toate v\u00e2rstele, inclusiv copiii, care sunt \u00een m\u0103sur\u0103 s\u0103 garanteze o colaborare acceptabil\u0103 pentru a asigura un rezultat fiabil al examin\u0103rii. Este folosit\u0103, \u00een special, \u00een toate materiile cunoscute sau cu risc de glaucom la pacien\u021bii cu afec\u021biuni ale corneei c\u00e2t \u0219i la cei care trebuie s\u0103 sufere o interven\u021bie chirurgical\u0103 cornean\u0103 Cross-Linking, transplant de cornee sau chirurgie refractiv\u0103.<\/p>\n

Este examinarea dureroas\u0103 sau periculoas\u0103?<\/h2>\n

\u00cen cazul pahimetriei cu ultrasunete (dup\u0103 aplicarea anestezicului la ochi), aceasta nu este o examinare dureroas\u0103. Anestezicul este utilizat pentru a evita senza\u021bia de durere \u0219i disconfort \u00een timp ce atingem suprafa\u021ba corneei cu o sond\u0103 mic\u0103. \u00cen cazul examin\u0103rii pahimetriei optice, este o examinare neinvaziv\u0103 deoarece nu exist\u0103 nici un contact cu suprafa\u021ba ocular\u0103.<\/p>\n

Cum se efectueaz\u0103 examinarea?<\/h2>\n

Pacientul se a\u0219eaz\u0103 pe un scaun \u00een timpul examin\u0103rii pahimetrice cu ultrasunete. Anestezicul se picur\u0103 \u00een ochi \u0219i medicul sprijin\u0103 o sond\u0103 pe suprafa\u021ba corneei pentru a detecta grosimea acesteia. M\u0103surarea poate fi repetat\u0103 dac\u0103 este necesar, \u00een diferite puncte ale suprafe\u021bei corneei, dac\u0103 este necesar. Atunci c\u00e2nd \u00eencepe examenul ochii pacientului capteaz\u0103 o surs\u0103 de lumin\u0103 \u00een mod continuu timp de c\u00e2teva secunde, \u00een timpul c\u0103reia instrumentul efectueaz\u0103 o serie de scan\u0103ri ale corneei. Un calculator dedicat efectueaz\u0103 analiza morfologic\u0103 \u0219i morfometric\u0103, extrage valoarea pahimetrica detectat\u0103 \u00een mai multe puncte ale suprafe\u021bei corneene \u0219i este detectat\u0103 valoarea minim\u0103 a grosimii corneei.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-77036","cure","type-cure","status-publish","hentry"],"yoast_head":"\nPahimetria cornean\u0103 - Humanitas.net<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"ro_RO\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Pahimetria cornean\u0103 - Humanitas.net\" \/>\n<meta property=\"og:description\" content=\"Pahimetria cornean\u0103   Ce este pahimetria cornean\u0103?
