Boitsebiso ba elektronike

Electroretinography ke teko ea ho lekanya karabelo ea motlakase ea lisele tse bonang khanya tsa leihlo, tse bitsoang melamu le likhou. Lisele tsena ke karolo ea leihlo (karolo e ka morao ea leihlo).

Ha u ntse u lutse fatše, mofani oa tlhokomelo ea bophelo o beha marotholi a senyehang ka mahlong a hau, ka hona o ke ke oa ba le bothata nakong ea tlhahlobo. Mahlo a hau a bulehile ka sesebelisoa se senyenyane se bitsoang speculum. Sesebelisoa sa motlakase (eleketrode) se behiloe leihlong ka leng.

Electrode e lekanya ts'ebetso ea motlakase ea leihlo ho latela khanya. Ho khanya mabone, 'me karabelo ea motlakase e tloha ho eleketrode ho ea skrineng se kang TV, moo e ka shebelloang le ho rekotoa. Mokhoa o tloaelehileng oa karabelo o na le maqhubu a bitsoang A le B.

Mofani oa thepa o tla nka likalo ka khanya ea kamore e tloaelehileng ebe o li kenya lefifing hape, kamora ho lumella metsotso e 20 hore mahlo a hau a fetohe.

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

Mekhoa e lutseng leihlong la hao e kanna ea utloa e batla e ngoapile. Teko e nka hora e le 'ngoe ho e etsa.

Teko ena e etsoa ho bona mathata a "retina". E boetse e na le thuso ho tseba hore na ho buuoa ka mahlo ho khothalletsoa.

Liphetho tse tloaelehileng tsa liteko li tla bontša mokhoa o tloaelehileng oa A le B ho arabela khanya ka 'ngoe.

Maemo a latelang a ka baka liphetho tse sa tloaelehang:

• Arteriosclerosis e nang le tšenyo ho retina
• Bofofu ba Congenital bosiu
• Congenital retinoschisis (ho arohana ha likarolo tsa retina)
• Selemo se seholo sa arteritis
• Meriana (chloroquine, hydroxychloroquine)
• Mucopolysaccharidosis
• Sehlopha sa Retinal
• Rod-cone dystrophy (retinitis pigmentosa)
• Tsietsi
• Khaello ea Vitamin A.

Cornea e ka fumana mengoapo oa nakoana holim'a metsi ho tsoa ho eleketrode. Ho seng joalo, ha ho na likotsi ka ts'ebetso ena.

Ha ua lokela ho itlotsa mahlo ka hora kamora tlhahlobo, hobane sena se ka lematsa lehlaka. Mofani oa hau o tla bua le uena ka liphetho tsa tlhahlobo le hore na li bolelang ho uena.
