Asayansi apeza njira yatsopano yochotsera ntchentche pamaso pawo

Mwinamwake, nthawi zambiri mwakhala mukuwona ntchentche zosamvetsetseka zomwe zikuyandama pamaso panu? Posachedwapa asayansi ayesa mankhwalawa kuti awathetse. Zotsatira za phunziro lawo, zomwe zinayesa mankhwala atsopanowa, zinafalitsidwa sabata yatha mu nyuzipepala ya JAMA Ophthalmology.

Chifukwa chiyani ntchentche zimawoneka pamaso

Choyamba, nkoyenera kumvetsa zomwe ntchentchezi zilidi. Nthaŵi zambiri, amawoneka ngati osagwirizana m'masomphenya, ngakhale nthawi zina amawoneka ngati madontho akuda kapena mawanga. Izi zabodza zimayambitsidwa ndi mapuloteni a collagen omwe amayendetsa mu madzi omwe ali kumbuyo kwa diso la maso ndipo amapanga mthunzi pa retina pamene kuwala kumalowa.

Nthaŵi zambiri, ntchentche patsogolo pa maso zimatha kunyalanyazidwa, koma kwa anthu ena, makamaka okalamba, vutoli likhoza kukhala lalikulu kwambiri ndipo limakhudza ngakhale masomphenya awo. Mavuto aakulu, ntchentche zikhoza kukhala chizindikiro cha retina. Koma, kachiwiri, ali ndi munthu aliyense, kotero kuti nthawi zambiri palibe chifukwa chodera nkhawa. Pazifukwa zovuta, vutoli limathetsedwa mothandizidwa ndi ntchito, koma pakali pano palibe mankhwala pa msika wa mankhwala omwe angathandize kuchotsa chizindikiro ichi.

Kuphunzira njira zopanda chithandizo

Aphunzitsi ophthalmic Dr. Chirag Shaz ndi Jeffrey Heyer wochokera ku Boston adachita phunziro latsopano kuti athetse vuto lopanda kuthetsa vutoli. Amanena kuti kwa zaka zambiri mankhwalawa akugwiritsidwa ntchito kuthetsa ntchentche, koma ngakhale tsopano pali zochepa zochepa zokhudzana ndi sayansi.

Phunziroli linakhudza odwala 52: 36 anadziwika ndi YAG laser vitreolysis, pamene ena onse anali ndi placebo pogwiritsa ntchito diode yofooka kwambiri.

Zotsatira

Patatha miyezi isanu ndi umodzi kuchokera kuchipatala, 54 peresenti ya ophunzira omwe analandira mankhwalawa a YAG adalongosola za kusintha kwakukulu kwa moyo wabwino poyerekeza ndi gulu lolamulira (9% okha). Mankhwalawa anali otetezeka, monga odwala sananene za zotsatira zake.

Koma musanakhale mankhwalawa, ntchito yowonjezera idzakhala yofunikira. Monga momwe olembawo amanenera, phunziroli linakhudza odwala 52 okha, ndipo nthawi yotsatira chithandizo sichinali chokwanira kuti potsiriza amvetse ngati ali ndi zotsatira zamuyaya. Kuwonjezera apo, zotsatira za nthawi yaitali sizidziwikabe.

Kuti tikhale ndi chidaliro chonse pa chithandizo cha chithandizo, asayansi adzafunika kuphunzitsa zazikulu zowonjezera, kuonjezera nthawi yake.
