Tlhahlobo ea lebone la sekhahla e sheba likarolo tse ka pele ho leihlo.

Lebone la selupu ke microscope e nang le matla a tlase e kopantsoeng le mohloli o matla oa khanya o matla o ka tsepamisoang joalo ka molamu o mosesane.

U tla lula setulong seletsa se behiloe ka pele ho uena. O tla kopuoa ho phomotsa selelu le phatla ea hau ho ts'ehetsa ho boloka hlooho ea hau e tsitsitse.

Mofani oa tlhokomelo ea bophelo o tla hlahloba mahlo a hau, haholo-holo mahlo a mahlo, cornea, conjunctiva, sclera le iris. Hangata dae e tšehla (fluorescein) e sebelisoa ho thusa ho hlahloba lehlaka le ho tabola. Dae e eketsoa joalo ka mahlo. Kapa, ​​mofani oa thepa a ka ama sekhechana sa pampiri se silafalitsoeng ke dae ka bosoeu ba leihlo la hao. Dae e hlatsoa ka leihlong ha u ntse u panya.

Ka mor'a moo, marotholi a ka beoa mahlong a hau ho holisa (ho holisa) barutoana ba hau. Marotholi a nka metsotso e 15 ho isa ho e 20 ho sebetsa. Tlhatlhobo ea lebone la slit e boetse e phetoa ho sebelisoa lense e ngoe e nyane e ts'oaretsoeng haufi le leihlo, ka hona mokokotlo oa leihlo o ka hlahlojoa.


Ha ho boitokiso bo khethehileng bo hlokahalang bakeng sa tlhahlobo ena.

Mahlo a hau a tla mamella leseli lihora tse 'maloa kamora tlhahlobo ha ho sebelisoa marotholi a ntlafatsang.

Teko ena e sebelisetsoa ho hlahloba:

  • Conjunctiva (lera le lesesaane le koahelang bokantle ba leihlo le karolo e tšoeu ea leihlo la leihlo)
  • Cornea (lense e hlakileng e kantle ka pele ho leihlo)
  • Mahlo a mahlo
  • Iris (karolo e mebala ea leihlo lipakeng tsa cornea le lense)
  • Lilense
  • Sclera (seaparo se tšoeu se ka ntle sa leihlo)

Meaho e ka leihlong e fumanoa e le ntho e tloaelehileng.

Tlhahlobo ea lebone e ka fumana mafu a mangata a leihlo, ho kenyelletsa:

  • Ho koahela lense ea leihlo (cataract)
  • Ho lematsa cornea
  • Lefu la mahlo a omileng
  • Ho lahleheloa ke pono e bohale ka lebaka la ho senyeha ha macular
  • Karohano ea retina le likarolo tsa eona tse e tšehetsang (sehlopha sa retina)
  • Thibelo ka mothapong o monyane kapa mothapong o tsamaisang mali ho isa le ho tsoa ho retina
  • Ho senyeha ho futsitsoeng ha retina (retinitis pigmentosa)
  • Ho ruruha le ho teneha ha uvea (uveitis), karolo e bohareng ea leihlo

Lethathamo lena ha le kenyeletse mafu ohle a mahlo.


Haeba o amohela marotholi ho ntlafatsa mahlo a hau bakeng sa ophthalmoscopy, pono ea hau e tla fifala.

  • Apara likhalase tsa mahlo ho itšireletsa mahlaseling a letsatsi, a ka u senyang mahlo.
  • E-re motho e mong au khannele hae.
  • Marotholi hangata a fela ka lihora tse 'maloa.

Maemong a sa tloaelehang, mahlo a ntseng a phahama a baka:

  • Tlhaselo ea glaucoma e tšesaane
  • Botsoa
  • Ho omella ha molomo
  • Ho tsuba
  • Ho nyekeloa le ho hlatsa

Biomicroscopy

  • Leihlo
  • Tlhahlobo ea lebone
  • Anatomy ea lense ea mahlo
