Vawiin hian mit natna pakhat, chutiang chhinchhiahna thlentu, mahse kan rama mi tam takin an hriat chian loh thu kan sawi dawn a ni. Chu chu Retinitis Pigmentosa, a tawi zawngin (RP) a ni.

A awlsam zawngin, Retinitis Pigmentosa (RP) hi eng nge ni?

Retinitis Pigmentosa (RP) hi natna pakhat chauh a ni lo. A nihna takah chuan mit natna pawl pakhat, rochun, chu chu genetically inherited tihna a ni. Hetiang dinhmunah hian i mit a sensitive ber, hnunglam chu retina an ti a.

I mit chu camera tha tak ang maiin han ngaihtuah teh. He camera film roll hi `(Retina)` tih a ni. Pawn lam atanga êng lo chhuak chu mit chhungah a lut a, he `(Retina)`, chu chu film-ah hian a rawn deng chuan electrical signal a siam a, thluak lamah a kal ta a ni. Thluak hian chu signal te chu thlalak angin a hrilhfiah a, ‘hmu’ tih hriatna min pe a ni. Tunah chuan han ngaihtuah teh, i camera chu eng ang pawhin tha mahse, a chhunga film awm chu a chhiat chuan i thlalak kha a chiang ang em? A chhuak dawn lo a ni lawm ni? Chu chu RP-ah pawh a thleng thin. `(Retina)` chhunga cell te chu zawi zawiin an chak lo va, hnathawh theih lohvin an awm ta a ni. Tichuan kan vision chu a bo zauh zauh a.

Hei hi kan pianpui dinhmun a ni. Mahse a natna lan chhuah dan hi naupan lai emaw, tleirawl lai emaw atang hian a lang tan fo thin. Pakhatnaah chuan zan lama mit hmuhna a tlahniam tan a. Tichuan, peripheral vision chu a bo zauh zauh a. Hun a kal zel a, he mit hi a zim lehzual a, kum 40 an tlin meuh chuan mi tam tak chuan mit hmuhna a tlahniam nasa hle. Ṭhenkhat chu dân anga mitdel pawh an ni thei. Mahse inthlak danglamna hi a nasat em avangin mi thenkhatin hei hi natna a ni tih an hriat theih nan hun rei tak a ngai a ni.

He hming hian eng nge a awmzia?

"Retinitis Pigmentosa" tih hming hi a takah chuan a dik lo deuh. Damdawi lamah chuan thumal pakhat chu "-itis" tia tawp a nih chuan 'inflammation' emaw 'inflammation' emaw tihna a ni. Entirnan, `(Appendicitis)` ang chi te hi. Mahse RP hi `(Retina)` inflammation a ni lo. Heta thil thleng hi `(Retina)` cell te chu an chak lo zauh zauh a, an atrophy ta a ni. Chuvangin hei hi a hming dik zawk chu `(Retinal Dystrophy).` tih hi a ni

Chuti a nih chuan "Pigmentosa" tih thumal hi eng nge a awmzia? He dinhmun nen hian inzawmna a nei a ni. Kan retina-a photoreceptor cells te an thih chuan pigment an chhuah chhuak thin. He pigment hi retina-ah a awm a. Doctorin mit a enfiah hian heng deposited pigment spots te hi a hmu thei a ni. Chuvang chuan a hmingah hian "Pigmentosa" tih thumal hi dah belh a ni.

RP natna lan chhuah dan chu engte nge ni?

Kan sawi tawh ang khan heng symptoms te hi a lo lang zawi zawi hle. Kum tam tak chhung chu zawi zawiin an lo thang lian thei a ni. Chuvangin a tir lamah chuan hriat harsa tak a ni thei.

Heng symptoms te hi eng nge ni tih i lo en ang u. Fiah taka hrethiam tur chuan hei hi hmun hnih ah then ila.

Engvangin nge hetiang dinhmun hi a lo awm?

Hei hi a chhan ber chu genetic variations vang a ni . A awlsam zawngin, kan gene-ah hian kan taksa siam dan leh a hnathawh dan tur hrilhfiahna kimchang tak a awm a. Hei hi in sakna atana hman blueprint ang a ni. He blueprint-ah hian, chu chu genes-ah hian danglamna emaw, chhiatna emaw a awm a nih chuan, chuta siam, chu chu kan taksa peng hrang hrangte hi a lo thang lian lo thei a, a thawk tha lo thei bawk.

Scientist-te chuan hetiang genetic change 100 vel RP thlen thei an hmuchhuak tawh a ni. He genetic defect hi i nu emaw i pa emaw hnen atangin i rochun thei a ni. A nih loh leh, i taksaah gene mutation thar a lo thleng thei a, i chhungte zingah tu mahin an nei lo.

Gene chi hrang hrang a awm avangin gene tin hian retina hi a tichhe dan a inang lo. Chuvang chuan RP hi mi hrang hrangah a inang lo. Mi thenkhat chuan an mit an hloh thuai thin. Mi dangte chuan an mit an hloh zawi hle. A châng chuan RP hi symptom dang tam takin a zui thei a, Usher syndrome ang chi natna dang angin a lang thei bawk.

Mit chhungah eng thil nge thleng tak tak?

Tlem a thuk deuh deuhin mit chhunga thil thleng hi han en ila. Kan sawi tawh ``Retina`` ah khan êng hmuchhuak thei cell chi khat bik a awm a. Hengte hi ``Photoreceptors`` kan ti a. Heng cell te hi mit chhunga êng lut chu la in electrical signal-ah a chantir a, thluaka thawn chhuaktu cell te an ni.

Photoreceptor hi chi hnih a awm a, chungte chu:

• Rods: Hengte hian thim zingah, chu chu êng hniam takah hmuh theihna min pe a ni. Tin, rawng an thliar hrang thei lo va, mit dum leh var chauh min pe a ni. Kan `(Retina)`-ah hian heng `(Rods)` hi maktaduai tam tak a awm a, a bik takin `(Retina)` chhehvel, chu chu a sir lehlamah a awm a ni.

RP ah chuan rod te hi a chhe hmasa fo thin . Chuvangin a symptom hmasa ber chu zan lama mit hmuh tlem leh peripheral vision hloh hi a ni. Hun a kal zel a, cone te pawh a chhe tan bawk. Chutih lai chuan rawng hmuh leh hnai taka hnathawh ang chi thilte chu a nghawng a ni.

He natna hi engtin nge doctor hian a hriat theih ang?

Heng symptoms te hi i neih chuan mit surgeon (Ophthalmologist) i pan tur a ni. I mit a enfiah ang. Mit enfiahna pangngai (routine eye exam) hian he natna lan chhuah dan hi a hriat theih a ni.

Natna finfiah nan hian test eng emaw zat a awm tlangpui a:

• Visual Field Test: Hei hian i peripheral vision a teh a, chu chu a sir lam atanga i hmuh theihna hlat zawng a ni. Hei hian tunnel vision i neih leh neih loh hriat nan a pui thei a ni.
• Slit Lamp leh Fundoscopy: I mit chhung lam (retina) enfiah nan hmanraw bik hman a ni. Hei hian RP nena inzawm pigment deposit awm leh awm loh a enfiah thei a ni.
• Retinal Imaging: Retina-a inthlak danglamna zir chianna atan high-resolution image lak a ni.
• ERG Test (Electroretinogram): Hei hi test bik deuh a ni. Heta tih tur chu i `(Retina)` atanga electrical signal chhuak te teh a, êng a chhan dan tur hriat a ni. RP ah chuan heng signal te hi a chak lo hle.
• Genetic Testing: He test hi thisen sample lak a, eng genetic defect nge natna thlentu dik tak hriatchhuah atanga tih theih a ni.

Hei hi eng enkawlna nge ni?

Hei hi ka hriat huat ber part chu a ni. Vanduaithlak takin Retinitis Pigmentosa hi damdawi a la awm lo. Mahse, beiseina bansan suh. He natna vei te tanpui tur leh nun awlsam zawka siam theih dan leh hmanraw tam tak a awm a.

I doctor chuan vision rehabilitation services-ah a refer thei che a ni. Chûng zîngah chuan:

Hetihlai hian scientist-te chuan he natna enkawlna tur hi an zirchiang chhunzawm zel a ni. Tunah hian experimental treatment engemaw zat a awm a, result duhawm tak a awm a:

• Gene Therapy: Hei hi beiseina lian ber a ni. Heta tih tur chu gene chhia siamthat tumna a ni. Tunah hian gene chi khat enkawlna pawmpui pakhat chauh a awm a, chu chu `(RPE65) a ni.` Mahse gene dang tan pawh zirchianna chak takin kalpui mek a ni.
• Vitamin A supplement: RP chi thenkhatah chuan vitamin A dose dik tak ei hian natna a tikhawtlai tih hmuhchhuah a ni. Mahse hei hi a pawimawh hle: Doctor rawn hmasa lovin vitamin A hi ei ngai suh. Mi thenkhat chuan vitamin A ei tam lutuk hian harsatna an tawk thei a, chuvangin hei hi i doctor chauhin thutlukna a siam theih a ni.
• Retinal Prosthesis: Hei hi electronic hmanrua a ni a, mit chhungah dah a ni. Vision engemaw zat a pe thei a ni. Mahse, mi tinah result a inang lo. Hei hi i tan a tha em tih doctor i zawt thei bawk.
