- hais dystrophic hloov pauv hauv fundus;

- retinal rubeosis;

- mob hnyav epiretinal gliosis.

Tus nqi ntawm kev ua haujlwm txawv ntawm tus nqi tseem ceeb. Nws yog suav nrog rau hauv tus account tus nqi ntawm retinal cheeb tsam raug. Lub tsev kho mob nws tus kheej ua lub luag haujlwm tseem ceeb hauv qhov teeb meem no, uas ua rau laser coagulation ntawm retina.

Rau nws txoj kev siv, cov tshuaj siv tshuaj, nrog rau cov cuab yeej siv kev kho mob, yog siv. Txoj kev zoo tshaj plaws yog laser vapolarization (laser coagulation ntawm lub ncauj tsev menyuam). Lub ntsiab kom zoo dua ntawm txoj kev no yog nws qhov tseeb. Nws yuav tsum tau muab sau tseg tias lub laser beam ua rau cov hlwb txawv txav, thaum lub hlwb noj qab nyob zoo nyob sab nraum qhov chaw phais.

Ib qho teeb meem tseem ceeb ntawm txoj kev kho mob saum toj no yog nws cov nqi. Yog li ntawd, gynecologists feem ntau sau ntawv laser vapolarization rau cov neeg mob uas nws lub ncauj tsev menyuam anomalies tsis kho nrog tshuaj.
