Ukuhlolwa kwesibani

Ukuhlolwa kwesibani sesibani kubheka izakhiwo ezingaphambi kweso.

Isibani esisikiwe siyisibonakhulu esinamandla aphansi sihlanganiswe nomthombo wokukhanya wekhwalithi ephezulu ongagxilwa njengogongolo oluncane.

Uzohlala esihlalweni ngensimbi ebekwe phambi kwakho. Uzocelwa ukuthi uphumule isilevu nebunzi lakho ekusekeleni ukuze ugcine ikhanda lakho lizinzile.

Umhlinzeki wezokunakekelwa kwempilo uzohlola amehlo akho, ikakhulukazi amajwabu amehlo, i-cornea, i-conjunctiva, i-sclera, ne-iris. Imvamisa udayi ophuzi (i-fluorescein) usetshenziselwa ukusiza ukuhlola ungqimba lwe-cornea kanye nolwelwesi. Idayi ingezwa njenge-eyedrop. Noma, umhlinzeki angathinta isiqeshana sephepha elinamabala odayi kokumhlophe kweso lakho. Udayi uhlanza uphume esweni ngezinyembezi lapho ucwayiza.

Okulandelayo, amaconsi angabekwa emehlweni akho ukunweba (ukukhulisa) abafundi bakho. Amaconsi athatha cishe imizuzu eyi-15 kuye kwengu-20 ukusebenza. Ukuhlolwa kwesibani se-slit-lamp kuyaphinda kuphindwe kusetshenziswa enye i-lens encane ebanjwe eduze kweso, ngakho-ke kungehliswa ngemuva kweso.

Akukho ukulungiselela okukhethekile okudingekayo kulolu vivinyo.

Amehlo akho azwela ekukhanyeni amahora ambalwa ngemuva kokuhlolwa uma kusetshenziswa amaconsi axegayo.

Lokhu kuhlolwa kusetshenziselwa ukuhlola lokhu:

• IConjunctiva (ulwelwesi oluncane olumboza ingaphakathi lejwabu leso nengxenye emhlophe yeso leso)
• ICornea (ilensi ecacile engaphandle ngaphambili kweso)
• Izinkophe
• Iris (ingxenye enemibala yeso phakathi kwe-cornea nelensi)
• Ilensi
• I-Sclera (ingubo emhlophe yangaphandle yeso)

Izakhiwo esweni zitholakala njengejwayelekile.

Ukuhlolwa kwesibani se-slit kungathola izifo eziningi zeso, kufaka phakathi:

• Ukufiphazwa kwelensi yeso (i-cataract)
• Ukulimala ku-cornea
• Isifo seso elomile
• Ukulahleka kombono obukhali ngenxa yokonakala kwe-macular
• Ukwehlukaniswa kwe-retina nezendlalelo zayo ezisekelayo (iqembu le-retinal)
• Ukuvaleka emthanjeni omncane noma emthanjeni ohambisa igazi noma ulibuyise ku-retina (ukuvalwa kwesitsha se-retinal)
• Ukwehla kwefa le-retina (retinitis pigmentosa)
• Ukuvuvukala nokucasuka kwe-uvea (uveitis), ungqimba ophakathi kweso

Lolu hlu alufaki zonke izifo ezikhona zeso.

Uma uthola amaconsi ukuze uvule amehlo akho nge-ophthalmoscopy, umbono wakho uzofiphala.

• Gqoka izibuko zelanga ukuvikela amehlo akho elangeni, okungalimaza amehlo akho.
• Yiba nomuntu okushayela ekhaya.
• Amaconsi avame ukuphela emahoreni amaningana.

Ezimweni ezingavamile, ama-eyedrops ahlukanisayo abangela:

• Ukuhlaselwa kwe-glaucoma enezingqimba ezincane
• Isiyezi
• Ukoma komlomo
• Ukuqhuma
• Isicanucanu nokuhlanza

I-Biomicroscopy

• Iso
• Ukuhlolwa kwesibani
• I-anatomy yelensi yamehlo
