He mit test bik (Pachymetry Test) hi i hre tak tak em? Kan sawi dun teh ang!

Mit lam doctor hnenah i kal a, "I mitmeng thickness kan check a ngai" tih ang chi hi i hre tawh em? Chu chu thil mak deuh niin i ngai mai thei. He mitmeng (cornea) thickness tehna hi eng nge ni? Chu chu a atana tih test kan tih chu a ni a, ``Pachymetry Test'' emaw ``Corneal Pachymetry Test.'' A awlsam zawngin sawi ila, i mit hmaa layer langtlang tak, i ``Cornea'' thickness chu a teh a ni.

Pachymetry test hi eng nge ni? Engvangin nge a pawimawh?

Awle, he `(Cornea)` hi eng nge a nih i en hmasa phawt ang u. Mit i nei a, a hma lamah chuan glass ang maia lang thei, membrane chak deuh a nei bawk. Darthlalang glass ang maiin. Hei hian thil chiang taka min hmuh theihna tura min puitu a ni a, chu chu mit chhunga êng chu a hruai lut a, chu chu kan focus theihna tura min puitu a ni. Tin, mit chu leivut leh hrik ang chi thil laka humhimtu shield pawimawh tak angin a thawk bawk.

Chuvangin, he `(Pachymetry)` test hian `(Cornea)` hi engzat nge a thick tih chiang takin a teh a ni. Hei hi test pawimawh tak a ni a, a chhan chu `(Cornea)` thickness a zirin mit natna thenkhat i neih leh neih loh hriat nan a pui a, chubakah enkawlna thenkhat atan i tling em tih hriat nan a pui bawk.

Thil dang pakhat chu, he `(Pachymetry)` test leh test dang `(Corneal Topography)` tih hi inzawmna tlem a awm a. `(Corneal Topography)` hian i `(Cornea)` chu color map a siam a. `(Cornea)` pianzia leh a chunglam chungchang tam tak a pe thei a ni.

He pachymetry test hi engtikah nge tih a nih?

I mit doctor hian he ``Pachymetry`` test hi tih a tum theihna tur dinhmun engemaw zat a awm. Eng nge an nih hi han thlir ila:

• Glaucoma: Hei hi mit chhunga pressure (IOP) sang lutuk avanga mit nerve tichhe thei leh mit tichhe thei natna a ni. Chuvangin, glaucoma i vei nia i rinhlelh a nih chuan, emaw, enkawl mek i nih chuan, i mit (cornea) thickness teh hi a pawimawh hle. Hei hi a chhan chu i mit (cornea) thickness hian mit pressure tehna tonometry test result a nghawng thei a ni.
• Refractive errors surgery: LASIK ang chi surgery neih i tum a, nearsightedness emaw farsightedness emaw avanga glasses vuah ngai i neih chuan Pachymetry test i neih a ngai ngei ang. Hei hi i mit (cornea) chu surgery tih theihna tur khawpa sei a nih leh nih loh hriat nan a ni.
• Mit natna: Mit natna (cornea) tibuaitu natna thenkhat a awm a, chungte chu mit (cornea) hydrops (mit (cornea tui a lo awm)), keratoconus (mit (cornea) hmalam panna hmun), Fuchs’ dystrophy (mit (cornea chhungril layer) tichhe thei natna) te hi a ni. He test hian heng natnate hi a hriat theih nan leh enkawl dan tur ruahmanna a siam thei a ni.
• Mit hliam: 1.1.Mit chunga thil a thlen hian mitmeng (cornea) a chhiat leh a thickness a nghawng em tih en nan pawh hman a ni.

A awlsam zawngin, he Pachymetry test atanga mitmeng thickness chungchanga data kan hmuh hian i mit chhunga pressure tehna Tonometry test result dik taka hriatthiamna kawngah a pui hle.

Engtin nge he pachymetry test hi tih a nih? Thil lian tak a ni em?

He test atan hian inbuatsaih vak a ngai lo. A tlangpuiin minute tlemte chhungin a zo thei. Chutianga tih theih dan tlangpui pahnih a awm a, chungte chu:

1. Optical Pachymetry hmanga thil tih dan

Hemiah hian thil thleng chu machine hmaa chair-a thut tir i nih hi a ni. I lu leh i hmui chu machine-ah hmun bik takah dah a ngai a ni. Tichuan machine chuan i mit thlalak a la a, chu thlalakte chu a zirchiang a, `(Cornea)` thickness chu a teh thin. Hetiang method ah hian engmahin i mit a khawih lo. A chang chuan tunlai hmanraw `(Optical Coherence Tomography - OCT)` tih ang chi te chu hemi atan hian an hmang thin. Hei hi hmanraw rang tak leh hrehawm lo tak a ni.

2. Ultrasonic Pachymetry hmanga tih a ni

Hetiang hmang hian doctor chuan i mit ah numbing drop a dah hmasa thin. Hei hian hun engemaw chen i mit a ti na a, chuvang chuan engmah hrehawmna i nei lo. Tichuan, hmanraw thianghlim, sterilized, pen ang chi, pachymeter an tih chu uluk takin i mitmeng chung lamah second tlemte chhung dah a ni. He instrument hian ultrasound wave a hmang a, chu chu high-frequency sound wave a ni a, chu chuan i mit (cornea) thickness a teh a ni. A tlangpuiin a thickness hi mitmeng lai takah teh a ni a, mahse a chang chuan hmun dang pawh teh theih a ni.

Pawimawh: I mit enfiah laiin mittui tlakna i dawng dawn tih i hriat chuan lirthei khalh ai chuan midang khalh tir che a tha ber. Mit drop thenkhat hian black pupil a tizau thei a, chu chuan mit hmuhna a ti fiah lo deuh thei bawk. Numbing drop hian a chang chuan mit hmuhnaah nghawng tlem a nei thei bawk.

He test hmang hian risk a awm em?

Hei hi i ngaihtuah ve tho a ni mai thei. I han en teh ang.

• Optical Pachymetry Method: Hetiang method hmang hian mit hi khawih a nih loh avangin sawi tur hlauhawm a awm lo. A him hle mai.
• Ultrasonic Pachymetry: Hetiang method hian risk lian tham a keng tel bawk a, mahse thil tenau tlemte a awm a, a thleng tlem hle a ni:
• Mit natna vei theihna chance tlem a awm (chuvang chuan hmanraw thianghlim hman a ni).
• Mit chu a sen deuh thei a, a hring thei a, a hring (mit irritation) emaw a awm thei bawk.
• Mi thenkhat chuan mittui tlakna (numbing eye drops) hian allergic reaction na lo tak an nei thei bawk.
• Pachymeter hi mit chungah a hmet chuan a chang chuan Cornea chung lamah hian hun eng emaw chen atan hliam tenau tak a hnutchhiah thei a ni. Hei hian ni reilote hnuah a dam leh ang.

A pawimawh ber chu mit endikna eng pawh hnua mit lama harsatna emaw, mit na emaw, thil danglam bik i neih chuan mit doctor hnenah i hriattir nghal tur a ni.

Engtin nge test result i hmuh theih ang? Engtin nge an hrilh che?

A tha ber chu test zawhah result i hmu nghal mai mai hi a ni. I doctor chuan chutah tak chuan an chungchang chu a sawipui thei che a ni.

United States-a survey an neihah chuan mi hrisel tak `(Cornea)` (Central Corneal Thickness - CCT) thickness chu 540 leh 550 micrometer `(micrometers)` emaw microns `(microns) inkar a ni. Mahse hei hi chu average value chauh a ni, hre reng ang che. I doctor chuan heng result atanga i sawi tur a rel hunah hian he hlutna chauh ni lovin, thil dang tam tak, i kum, i hriselna zawng zawng, leh mit natna dang i neih leh neih loh te pawh a ngaihtuah ang. Chuvangin, i `(Cornea)` thickness hi he normal range pawnah ni mahse, i mit a hrisel mai thei.

Results a pangngai lo a nih chuan eng nge ka tih leh ang?

I Pachymetry test result chu a normal range chhungah a awm lo ang tih han ngaihtuah teh. Chuti a nih chuan eng nge thleng? Doctor chuan heng result te hmang hian eng nge tih tur tih a rel thin.

• Glaucoma tan: Glaucoma i neih chuan he corneal thickness data hian i enkawlna i dawn dan leh i enkawlna chu thlak danglam a ngai em tih hriat theih nan a pui thei a ni.
• Mit surgery atan: `(LASIK)` ang chi surgery atan i inbuatsaih a nih chuan `(Cornea)` thickness hi a pawimawh hle. A chhan chu, `(Cornea)` chu operation tih theihna tur khawpa thuk a nih loh chuan, operation hnuah `(Corneal ectasia)` tih hming pu condition a awm thei a ni. Chu chu `(Cornea)` chu a chak lo va, hmalam a pan chhuak tihna a ni. Chu chuan mit hmuhnaah nghawng lian tak a nei thei a ni. Chuvangin, chu risk tihziaawmna turin he test hi surgery hmain tih a ni.

I mit (cornea) a thim a nih chuan eng nge a awmzia?

Mi thenkhat mitmeng (cornea) hi a tlangpui aia thuk deuh a ni thei. Chu chu eng nge a awmzia?

• A tlangpuiin mit (cornea) thick zawk nei te hian glaucoma vei an nei tlem zawk tih hmuhchhuah a ni.
• Tin, mitmeng thick tak nei mi mit pressure (IOP) tehnaah chuan pressure tak tak aiin value sang zawk a lantir thei bawk. Chu chu, mit (cornea) a thuk zawk avangin pressure gauge hian reading dik lo a pe thei tihna a ni.

Chuvangin, i mitmeng (cornea) thickness dik tak a hriat chuan i doctor chuan i mit pressure dik takin a teh thei a , dik takin a diagnose thei bawk che a ni.

Chuti a nih chuan, he thawnthu atang hian eng thil nge kan hriat reng tur?

Okay, tunah chuan `(Pachymetry Test)` chungchangah hian ngaihdan tha tak i neih ka beisei. A awlsam zawngin sawi ila, hei hi natna nei lo, test rang tak a ni a, i mit hriselna atan a pawimawh hle.

Hrereng:I mit doctor-in Pachymetry test a rawt a nih chuan i mit (cornea) thickness an hriat a ngai a, i intraocular pressure (IOP) dik taka an teh a ngai a, mit surgery atana candidate tha tak i nih leh nih loh emaw, glaucoma ang chi natna enkawlna tur ruahmanna siam emaw an mamawh tihna a ni. Hei hi i mit hmuhna humhim tura pui thei tur step pakhat chauh a ni.

Chuvangin damdawi lam thurawn zawm a pawimawh. Zawhna i neih chuan i doctor zawh hreh suh.
