Wali oyimiridde mu maaso g’endabirwamu n’oyaka akataala akatono mu liiso lyo? Bw’onookola bw’otyo, ojja kulaba ng’akatono akaddugavu akali wakati w’eriiso lyo akayitibwa ‘pupil’, kakonziba ng’ekitangaala kikaaka. Ekitangaala bwe kiggyibwawo, kigaziwa. Eno nkola ya bulijjo mu maaso amalamu. Ekikulu kiri nti ekitangaala bwe kyaka ku liiso erimu, ekituli mu maaso gombi kirina okukonziba mu kiseera kye kimu. Naye oluusi, eriiso erimu liyinza obutaddamu bulungi kitangaala kino. Ekyo kye tuyita Marcus Gunn Pupil mu busawo.
Mu ngeri ennyangu, Marcus Gunn Pupil (RAPD) kye ki?
Okay, kino ka tukiteeke mu ngeri ennyangu. Lowooza ku maaso go ng’abakozi babiri abakolera wamu. Ekitangaala kabonero akava mu mutwe gwo (i.e., obwongo bwo). Eriiso erimu bwe lifuna akabonero kano, amaaso gombi galina okukolera awamu ne gabetenta ebiddugavu byombi.
Naye ekitangaala bwe kikuba eriiso erikosebwa ery’omuntu alina Marcus Gunn Pupil, eriiso eryo terifuna bulungi bubaka ne bubuweereza ku bwongo. N’ekyavaamu, enzirugavu enjeru mu maaso gombi tezikendeera bulungi. Oluusi mu kifo ky’okukendeera, ziyinza okulabika nga zikula katono.
Ekikulu kiri nti Marcus Gunn Pupil si bulwadde ku bwakyo. Kabonero kakulu nnyo nti waliwo ekizibu munda mu liiso lyo naddala mu retina oba optic nerve. N’olwekyo, bw’olaba akabonero kano, kyetaagisa nnyo okuzuula ekivaako. Abasawo era kino bakiyita Relative Afferent Pupillary Defect (RAPD).
Lwaki kino kigenda mu maaso? Ensonga ki eziviirako kino?
Marcus Gunn Pupil esinga kuva ku kwonooneka kwa retina yo oba optic nerve, etambuza obubaka okuva ku liiso okutuuka ku bwongo. Ka tulabe embeera z’obujjanjabi enkulu eziyinza okukosa kino.
| Kakwakkulizo | Ennyinyonnyola ennyangu |
|---|---|
| Obulwadde bw’obusimu bw’amaaso | Okuzimba oba okukwatibwa obulwadde bw’obusimu bw’amaaso. Kino kitera nnyo okuvaako RAPD. |
| Obulwadde bwa Glaucoma | Okwonooneka kw’obusimu bw’amaaso olw’okunyigirizibwa okweyongera munda mu liiso. Wadde nga kitera okukwata amaaso gombi kyenkanyi, RAPD esobola okubaawo ng’amaaso agasukka mu limu gakoseddwa. |
| Okukutuka kw’amaaso g’amaaso | Okukutuka kw’amaaso (retina detachment) kwe kwawula ekitundu ky’amaaso (retina), oluwuzi oluli munda mu liiso, okuva ku bitundu ebiguwanirira. Eno mbeera ya maanyi nnyo. |
| Okuzibikira kw’omusuwa gw’amaaso ogw’omu makkati (ischemic central retinal vein). | Okuzibikira omusuwa omukulu ogugabira omusaayi mu retina. |
| Okukendeera kw’amaaso | Okwonooneka okw’olubeerera ku busimu bw’amaaso olw’ensonga ezimu. |
| Ebizimba by’amaaso | Okunyigirizibwa kw’obusimu bw’amaaso olw’ebizimba bya kookolo oba ebitali bya kookolo. |
| Obuvune mu maaso | Okwonooneka kw’obusimu bw’amaaso oba retina olw’akabenje ak’amaanyi, okwokya oba yinfekisoni. |
Okugatta ku ekyo, ekifaananyi kya Marcus Gunn Pupil tekitera kulabibwa mu mbeera ez’amaanyi ez’okuzimba amaaso , oba “eriiso erigayaavu,” n’okuzimba amaaso okw’amaanyi .
Kino okisanga otya Omusawo?
Kino kintu ky’otosobola kusanga waka. Waliwo okukebera okw’enjawulo omusawo kw’akola ku kino. Kiyitibwa "Swinging flashlight test." Era kiyitibwa ekigezo kya Marcus Gunn.
Kino kikolebwa bwe kiti:
1. Omusawo ajja kukutwala mu kisenge ekirimu enzikiza katono.
2. Oluvannyuma ng’okozesa akamuli akatono, eyaka ekitangaala mu buli liiso okumala sekondi ntono.
3. Oluvannyuma kyusa mangu ettaala ku liiso eddala.
4. Kyuusa ekitangaala okudda n’okudda bwe kiti emirundi mitono, nga weetegereza bulungi oba entangawuuzi zo zombi ez’amaaso amaddugavu ziddamu ekitangaala mu ngeri y’emu, oba emu yeeyisa mu ngeri ya njawulo ku ndala.
Mu muntu omulamu obulungi, ekisenge ky’amaaso gombi kirina okukendeera wamu buli ekitangaala lwe kigakuba. Wabula ettaala bw’ekoleezebwa mu liiso ly’omuntu alina RAPD erikosebwa, iris tekendeera bulungi, wabula esigala nga ya sayizi y’emu oba egaziwa katono. Kino kireetera omusawo okumanya nti waliwo ekizibu.
Embeera eno ejjanjabibwa etya?
Kino kikulu nnyo okukitegeera. Tewali bujjanjabi butongole eri Marcus Gunn Pupil. Kubanga si bulwadde. Obujjanjabi bulijjo bukwata ku mbeera eyaliwo eyabuleeta.
Okugeza nga:
- Singa ekivaako bulwadde bwa optic neuritis , omusawo ayinza okukuwa eddagala nga steroids eriweebwa mu misuwa.
- Singa ekivaako kizibu kya glaucoma , amatondo g’amaaso gajja kuweebwa okufuga puleesa mu liiso.
- If the cause is retinal detachment , enkola za layisi oba okulongoosa kiyinza okwetaagisa okukitereeza.
N’olwekyo, omusawo wo ajja kusooka okukola ebigezo ebyetaagisa okuzuula ekituufu ekivaako RAPD. Olwo, ajja kukuteesa ku bujjanjabi obusinga obulungi gy’oli okusinziira ku nsonga eyo.
Ddi lw’osaanidde okulaba omusawo mu bwangu?
Okulaba amaaso kye kimu ku bintu byaffe eby’omuwendo. N’olwekyo, tobuusa maaso nkyukakyuka yonna mu maaso go. Bw’oba olina obubonero buno wammanga, kakasa nti ogenda ew’omusawo naddala omusawo w’amaaso.
- Okulumwa amaaso oba obutabeera bulungi.
- Okulaba okutali kwa maanyi oba okulaba ebintu nga bibiri.
- Obuzibu okulaba ekiro .
- Okulaba amataala agayakaayakana (flashes) oba floaters mu kulaba kwo.
- Ekitundu ky’ekifo kyo eky’okulaba kifuuka ekizikiza oba ekitalabika.
Bw'ofuna obubonero buno bwonna, tobugoba ng'ogamba nti "ekintu ekitono kyokka." Laba omusawo amangu ddala nga bwe kisoboka. Kubanga mu mbeera zino, gy’okoma okutandika amangu obujjanjabi, emikisa gyo egy’okutaasa amaaso go gye gikoma okubeera emirungi.
Obubaka Obutwala Awaka
- Marcus Gunn Pupil (RAPD) si bulwadde, kabonero kakulu mu by’obujjanjabi akalaga nti olina obuzibu ku busimu bw’amaaso oba retina y’eriiso lyo.
- Wadde ng’obubonero buno bwokka tebuleeta bulabe eri bulamu, embeera ebuleeta eyinza okuba ey’amaanyi era nga yeetaaga okujjanjabibwa.
- Omusawo wo asobola okuzuula embeera eno ng'akozesa okukebera okwangu okuyitibwa "swinging flashlight test."
- Obujjanjabi si bwa kabonero ka Marcus Gunn Pupil, wabula embeera eyaliwo eyabuleeta. Kino kiyinza okwetaagisa okukozesa eddagala, layisi oba okulongoosebwa.
- Bw’olaba enkyukakyuka yonna mu kulaba kwo (obulumi, okuziba amaaso, okuziba amaaso ekiro), genda mangu omusawo awatali kulwa.
