Chii Chinonzi Central Serous Retinopathy?

Central serous retinopathy (CSR) inonzi retinal condition iyo inobata vaduku kune vanhu vepakati pepakati vasina zviratidzo zvekare kana zviratidzo zverwere re retinal. Ivhareji yemakore ekutanga inenge pakati pe30s, asi inotangira kubva kuma20 kusvika kuma1950. Inoratidzika kunge inobata varume vakawanda kupfuura vakadzi kuburikidza nehuwandu hwe10 kusvika ku1, uye vamwe veCaucasian kupfuura chero imwe yerudzi. Zvinofadza, inoratidzika kunge inobata vanhu vane chimiro-A hukama, zvakare.

Zviratidzo

Vanhu vane CSR vanowanzotonyunyutika kana kusvibiswa mukati, pane imwe ziso. Inogona kukanganisa maziso maviri, asi izvi hazviwanzoitiki. Vanhu vanosimba CSR dzimwe nguva vanoona kwenguva refu , uye vanogona kunyunyutira mitsetse yakajeka ichioneka yakatsauka kana yakagadzika.

Zvinokonzera

CSR dzimwe nguva inonzi "idiopathic" serous chorioretinopathy, nokuti chikonzero chaicho hachizivikanwi. Pane mhirizhonga yakawanda munharaunda yezvokurapa kuti nei vamwe vanhu vachikudziridza chirwere ichi; nyaya inowanzogara inowanzoita seinoita kushungurudzika, uye mamiriro ezvinhu anoita seanoitika kana kunetseka kwepamusoro kuchikwirira muupenyu hwemunhu. Uyewo, vanhu vanotora steroid oral vanenge vari pangozi shoma yekukura chirwere. Kusava nehope kunoratidzikawo kunobatsira.

Mamiriro acho anotanga pakati pezvikamu zviviri zveziso. I-photoreceptor yechando ye retina inopfuura pamusoro peiyroid , imwe nheyo inoshanda kuti iwane retina.

Pakati pejairo uye photoreceptor yepamusoro ndeyekuyera kwe retinal pigment epithelial cells, inonzi RPE. RPE inotarisa kutenderera kwezvibereko uye mvura inopinda mu retina.

Apo munhu anovaka CSR, RPE inobata munharaunda ye macular ye retina. Iyo macula chikamu chakanyanya chepakati retina chinotitaurira zvakajeka, zvakajeka maonero epakati.

Kazhinji RPE masero ane masangano akaoma kwazvo; idzi zvisungo zvakasimba zvinodzivisa kupisa kwemvura. MuCRR, chimwe chinhu chinoitika kuitira kuti masangano aya asunungure uye aparadze, achibvumira kushanduka kwemvura kuchidonha. Mamwe masero anoputsika, uye RPE yakasara inovhara kuumba krisiti duku munzvimbo ye macula. Iyo cyst inoshandura chimiro che retina (yakafanana nekukandira firimu mune kamera) uye inokanganisa maonero.

Kuziva

Nzira dzinotevera dzinogona kushandiswa kuona CSR:

1. Ophthalmoscopy: Vanachiremba veziso vanoshandisa nzira dzakasiyana-siyana kuti vatarise mukati meziso. Izvi zvingaita kana zvisingasanganisi zvakanakira kufungisisa maziso emeso kuti awedzere mudzidzi kuitira kuti chiremba aone nyore nyore mukati memeso. Kazhinji, cyst kana bubble yematumbu zvinogona kuonekwa.
2. Optical coherence tomography (OCT): OCT inoshandisa chiedza kuti zvionekwe zvikamu zvakasiyana zve retina. Uyu muedzo unopa chiremba maonero akajeka kwazvo kuti aone kana kunyatsokonzera kubuda kwemvura kuripo. Chiyero hachina maturo, nokukurumidza uye kazhinji hachidi kuti madonhwe aiswe muziso.
3. Fluorescein angiography: Vanachiremba dzimwe nguva vanoshandisa nzira yekujoya dhayi chaiyo muropa rekutsvaga ropa, uye inotora kuparadzirwa kweiyi iri mukati meziso.

Kurapa

CSR inorapwa chete mushure mekunge ichitarisa kunyatsofungisisa, sezvo dzakawanda zviitiko zvinoguma pasina kusarudzwa.

Zvinokurudzirwa kuti murwere aedze kuzorora uye kugamuchira maawa masere ekurara usiku, uye nguva dzose kurovedza muviri kunonyatsokurudzirwa. Kana chirwere chinoramba chiripo mushure memwedzi 4-6, vanachiremba vemazuva ano vanowanzobata CSR nenzira dzinotevera:

• Laser photocoagulation: Photocoagulation inzira inoshandiswa nachiremba kushandisa laser thermal panzvimbo yemvura. Iyo laser inokonzera unyoro kwazvo, inobatsira ruvara rwemavara mu pigment epithelial cells, kuvhara kupisa kwemvura.
• Photodynamic Therapy (PDT): PDT inoshandisa imwe yemagetsi yechiedza pamwe nemamwe makemikari e photoactive, anonzi Visudyne, kuderedza kuparara kwemvura uye kudzivirira pakurwisana kwemaitiro akaoma echirwere chacho.

Zvaunofanira Kuziva Nezve CSR

Kunyange zvazvo central central serous retinopathy inogona kukuvadza pane zvawakaratidzwa, vanhu vazhinji vane huwandu hwakanaka hwehutano pasina hutano zvachose. Vanhu vakawanda vanoona zviratidzo zvekunge 20 / 20-20 / 40 mukati memakore 1-6. Dzimwe nguva vanenge vachiri zvimwe zvakasara zvinokanganisa zvoratidzwa, asi zvakanyanyisa.

Kana CSR isingaporegi mumwedzi mitanhatu, vanachiremba vazhinji vachaona kurapwa. Kazhinji, kunetseka kwakakomba kunogona kukura apo mitsipa yeropa kubva kune choroid inotanga kukura kuva nzvimbo pasi pe retina. Zvisikwa zvidiki zvinogona kuumba, zvinogona kukonzera kurasikirwa kwemaono kana kusiyiwa kusati kwaitwa.
