Iliso kunye ne-orbit ultrasound

Iliso kunye ne-orbit ultrasound luvavanyo lokujonga indawo yamehlo. Ikwalinganisa ubungakanani kunye nolwakhiwo lweliso.

Uvavanyo luhlala lwenziwa kwiofisi ye-ophthalmologist okanye kwisebe le-ophthalmology lesibhedlele okanye ikliniki.

Iliso lakho liphelelwe ngamayeza (amathontsi okubulala iintlungu). I-wand ye-ultrasound (i-transducer) ibekwe ngokuchasene nomphezulu wamehlo.

I-ultrasound isebenzisa amaza esandi ahamba ngesantya esiphezulu ahamba ngamehlo. Ukuboniswa (kwamahlokondiba) amaza esandi enza umfanekiso wesakhiwo seliso. Uvavanyo luthatha malunga nemizuzu eli-15.

Zimbini iintlobo zokuskena: Iskena sokuskena kunye neB-scan.

Ukuskena i-A:

• Uya kuhlala uhlala esitulweni kwaye ubeke isilevu kwindawo yokuphumla. Uya kujonga ngqo phambili.
• Inkqubo encinci ibekwe ngokuchasene neliso lakho.
• Uvavanyo luyakwenziwa nawe ngokulala umva. Ngale ndlela, ikomityi ezaliswe lulwelo ibekwa iliso lakho ukwenza uvavanyo.

Ukuskena i-B:

• Uya kuhlala phantsi kwaye unokucelwa ukuba ujonge kumacala amaninzi. Uvavanyo luhlala lwenziwa xa amehlo akho evaliwe.
• Ijeli ibekwe kulusu lweenkophe zakho. Inkqubo ye-B-scan ibekwe ngobunono ngokuchasene neenkophe zakho ukwenza uvavanyo.

Akukho lungiselelo lukhethekileyo luyafuneka kolu vavanyo.

Iliso lakho liphelelwe ngamandla, ke akufuneki ukuba ube nokungonwabi. Unokucelwa ukuba ujonge kumacala ahlukeneyo ukuphucula umfanekiso we-ultrasound okanye unokujonga iindawo ezahlukeneyo zeliso lakho.

Ijeli esetyenziswe nge-B-scan inokuhla esidleleni, kodwa awuyi kuva ukungonwabi okanye iintlungu.

Ungaludinga olu vavanyo ukuba uneengxaki zamehlo okanye ezinye iingxaki zamehlo.

I-A-scan ultrasound ilinganisa iliso ukumisela amandla afanelekileyo okufakelwa kwelensi ngaphambi kotyando lwamehlo.

I-B-scan yenziwa ukujonga indawo engaphakathi yamehlo okanye indawo esemva kweliso engabonakaliyo ngokuthe ngqo. Oku kunokwenzeka xa une-cataract okanye ezinye iimeko ezenza kube nzima ukuba ugqirha abone ngasemva kweliso lakho. Uvavanyo lunokunceda ekuchongeni i-retinal detachment, tumors, okanye ezinye iingxaki.

Ukuskena i-A, imilinganiselo yamehlo ikuluhlu oluqhelekileyo.

Ukuskena i-B, ulwakhiwo lweliso kunye nokujikeleza kubonakala kuqhelekile.

Ukuskena kwe-B kunokubonisa:

• Ukopha kwijel ecacileyo (vitreous) egcwalisa umva kweliso (vitreous hemorrhage)
• Umhlaza we-retina (i-retinoblastoma), phantsi kwe-retina, okanye kwezinye iindawo zeliso (njenge-melanoma)
• Izicubu ezonakalisiweyo okanye ukonzakala kwisokethi yebhony (orbit) ejikeleze kwaye ikhusele iliso
• Amalungu angaphandle
• Ukutsala i-retina ngasemva kweliso (i-retinal detachment)
• Ukudumba (ukudumba)

Ukuthintela ukukrwela i-cornea, musa ukurabha iliso elibukhali de i-anesthetic iphele (malunga nemizuzu eyi-15). Azikho ezinye iingozi.

I-Echography - ukujikeleza kwamehlo; I-Ultrasound - ukujikeleza kwamehlo; I-Ocular ultrasonography; I-Orbital ultrasonography
