I-Pachymetry Test

I-Pachymetry iyisivivinyo sokuxilonga esibalulekile ku-ophthalmology, ngokuyinhloko esetshenziselwa ukukala ukushuba kwe-cornea. Ukuhlolwa kubaluleke kakhulu ekuhloleni impilo ye-cornea, ukuhlonza izimo ezihlukahlukene zamehlo, nokuqapha iziguli ezenza izinqubo ezifana nokuhlinzwa okuhlanjululwayo. Njengoba i-cornea idlala indima ebalulekile embonweni, ukuqonda ukujiya kwayo kunganikeza ukuqonda okubalulekile empilweni yamehlo iyonke futhi kusize ekutholeni izinkinga eziwumsuka ezifana ne-glaucoma, i-corneal edema, noma i-keratoconus.

Kuyini ukuhlolwa kwe-Pachymetry?

I-Pachymetry isivivinyo esingahlanyisi esikala ukujiya kwe-cornea, ukwakheka okusobala, okumise okwedome ngaphambili kweso. I-cornea idlala indima ebalulekile ekugxiliseni ukukhanya ku-retina, futhi ukujiya kwayo kungathonya impilo yamehlo iyonke. Ukuhlolwa kwe-pachymetry kuvame ukwenziwa kusetshenziswa idivayisi ye-ultrasound noma isithwebuli se-laser.

Ngesikhathi senqubo, idivayisi ikhipha amaza omsindo noma ukukhanya ukuze kukale ukujiya kwekhone endaweni ethile. Lezi zilinganiso zinikeza ulwazi olubalulekile olusiza ukuhlonza uhla lwezimo zamehlo, ukuhlela ukuhlinzwa, nokuhlola ubungozi bezinkinga ezigulini ezinezifo ezithile zamehlo.

Kungani I-Pachymetry Ibalulekile?

Ukuqina kwe-cornea kungathinta ukunemba kokuhlolwa kwamehlo okuthile, njengezilinganiso ze-intraocular pressure (IOP), ezibalulekile ekuxilongeni i-glaucoma. Eqinisweni, ukushuba kwe-corneal kungenye yezinto ezibalulekile ekunqumeni ubungozi besiguli ku-glaucoma. I-cornea ewugqinsi ingaholela ekufundweni okuphansi kokucindezelwa kwamehlo, kuyilapho i-cornea ezacile ingaholela ekufundweni okuphezulu okungamanga, okungadukisa ukuxilongwa. Ngokulinganisa ubukhulu be-corneal, i-pachymetry isiza ukuhlinzeka ngokuxilongwa okunembile futhi inqume uhlelo olufanele lokwelapha.

Ngabe Isivivinyo Se-Pachymetry Sisebenza Kanjani?

I-Pachymetry isebenzisa amaza omsindo noma ukukhanya ukukala ukujiya kwekhone ngokunemba okuphezulu. Izindlela ezimbili eziyinhloko zokwenza ukuhlolwa kwe-pachymetry yizi:

1. I-Ultrasound Pachymetry

I-Ultrasound pachymetry ihlanganisa ukusebenzisa i-ultrasound probe ekhipha amaza omsindo we-high-frequency ukukala ukujiya kwe-corneal. I-probe ibekwe ngobumnene ebusweni beso (noma i-anesthetic yendawo isetshenziswa esweni ngaphambi kwalesi sinyathelo), futhi amagagasi omsindo asetshenziselwa ukunquma ibanga phakathi kwendawo yangaphambili nangemuva ye-cornea. Idatha ibe isicutshungulwa ukunikeza isilinganiso esinembile sogqinsi lwekhone.

2. I-Optical Pachymetry (kusetshenziswa i-laser)

I-Laser pachymetry iyindlela ethuthuke kakhulu, engathinteki esebenzisa amaza okukhanya ukukala ukujiya kwe-corneal. I-laser iqondiswe esweni, futhi ukukhanya kuboniswa emuva kudivayisi, ukuyivumela ukuthi ilinganise ukushuba kwe-cornea ngaphandle kokuthinta iso ngokomzimba. Le ndlela ivame ukusetshenziswa kuzilungiselelo zomtholampilo ngoba ikhululekile esigulini futhi inikeza ukunemba okuphezulu.

Zombili izindlela ziyasebenza ekulinganiseni ukujiya kwe-cornea, futhi ukukhetha phakathi kwalokhu kuncike ezidingweni ezithile zesiguli kanye nodokotela.

Ukusetshenziswa kwe-Pachymetry Test

I-Pachymetry Test inokusetshenziswa okuningana okubalulekile ekuhlonzeni nasekulawuleni izimo zamehlo ezahlukahlukene. Ezinye zezinhlelo zokusebenza ezivame kakhulu zihlanganisa:

1. Ukuhlola Ingozi Ye-Glaucoma

I-Pachymetry idlala indima ebalulekile ekuhloleni ingozi ye-glaucoma, isimo lapho ukulimala kwe-optic nerve kungaholela ekulahlekelweni kombono. Ukuhlolwa kusiza odokotela bathole ukuthi ingabe i-cornea yesiguli incane kakhulu noma iwugqinsi, okungaba nomthelela ekunembeni kokufundwa kwengcindezi ye-intraocular. Uma i-cornea incane kakhulu, ingozi yokuthola i-glaucoma ingase ibe phezulu, futhi ukuqapha okwengeziwe kuyadingeka.

2. Ukuhlela Ukuhlinzwa Kwe-Refractive

Ezigulini ezicabangela ukuhlinzwa kwe-refractive (okufana ne-LASIK noma i-PRK), i-pachymetry ibalulekile ekunqumeni ukuthi ingabe i-cornea iwugqinsi ngokwanele ukuze ihlinzwe ngokuphephile. Ku-LASIK, isibonelo, ezinye zezicubu ze-cornea ziyasuswa ukuze kulungiswe umbono, futhi inani elithile lokuqina kufanele ligcinwe ukuze kuqinisekiswe ukuthi inqubo iphephile futhi iyasebenza.

3. Ukuqapha i-Keratoconus

I-Keratoconus iyinkinga yamehlo eqhubekayo lapho i-cornea iba mncane futhi iqhume ngaphandle, okubangela ukungaboni kahle. Ukuhlolwa kwe-pachymetry okuvamile kungasiza ukuqapha ukuqhubeka kwe-keratoconus ngokulandelela izinguquko ekugqimeni kwe-corneal. Lolu lwazi lungasiza ekuqondiseni izinqumo zokwelashwa, okuhlanganisa isidingo sokuxhumanisa i-corneal noma ngisho nokufakelwa kwe-corneal ezimeni ezinzima.

4. Ukuhlola I-Corneal Edema

I-Corneal edema, noma ukuvuvukala kwe-cornea, kungenzeka ngenxa yezimo ezihlukahlukene, okuhlanganisa izifo zamehlo, ukuhlinzwa, noma ukuhlukumezeka. I-Pachymetry isiza ukuhlola ukuqina kokuvuvukala kwe-cornea futhi iqaphe ukululama ngemva kokuhlinzwa noma ukulimala.

5. Ukuhlonza Izifo Ze-Corneal

I-Pachymetry ingasetshenziswa futhi ukuze kutholwe okunye ukungahambi kahle kwe-corneal, njenge-corneal dystrophies noma izibazi ze-cornea. Kusiza odokotela balandelele ukuqhubeka kwalezi zimo futhi banqume inkambo efanele yesenzo.

Imiphumela Evamile Nengavamile Ye-Pachymetry

Imiphumela Ejwayelekile

Ubukhulu be-corneal obumaphakathi kubantu abaningi buwela phakathi kwebanga lama-micrometer angama-520 kuye kwangama-550. Nokho, kungase kube khona ukuhluka okuncane okusekelwe ezintweni ezifana neminyaka, ubulili, kanye nobuhlanga. I-cornea evamile inogqinsi olufana ngokuqhathaniswa kuzo zonke izendlalelo zayo, futhi ukufundwa okuwela phakathi kwebanga elivamile ngokuvamile kubonisa ukusebenza kwe-cornea enempilo.

Imiphumela Engavamile

Izacile kunama-cornea avamile (ngaphansi kwama-micrometer angu-500) ingaphakamisa ingozi ephezulu yokuba ne-glaucoma noma ibonise ezinye izimo ezifana ne-keratoconus noma i-corneal dystrophy. I-cornea ezacile ingase futhi yenze umuntu angakufanelekeli ukuhlinzwa ngenxa yengozi yezinkinga ngesikhathi nangemva kwenqubo.

Ngakolunye uhlangothi, ama-cornea ajiyile (ngaphezu kwama-micrometer angu-600) angase aholele ekufundweni kwengcindezi ye-intraocular ephansi ngokungekho emthethweni, okungase kufihle ukuba khona kwe-glaucoma. Kubalulekile ukuhlanganisa imiphumela ye-pachymetry nezinye izivivinyo zokuxilonga, njenge-tonometry, ukuthola ukuhlolwa okunembile kwempilo yamehlo.
