How long does it take for gas bubble to go away after retina surgery?
SF6 gas stays in the eye for about one month; C3F8 gas remains for about two months. SF6 gas is used most often, while C3F8 gas is reserved for more complex retinal detachments and some macular holes. Air stays in the eye for about one week.
How long does vitrectomy gas bubble last?
The longevity of the gas bubble varies among patients but is typically about 3 to 5 days for air, 2 to 3 weeks for SF6, and approximately 6 to 8 weeks for C3F8. Optimizing the gas fill in eyes undergoing vitreous surgery requires a complete vitrectomy.
What kind of gas is used for retina surgery?
Patients who have had vitreoretinal surgery often have a gas bubble deliberately left within the eye as it helps keep the retina attached whilst adhesions develop. Filtered room air, sulfurhexafluoride (SF6) and perfluoropropane (C3F8) are the most commonly used gases.
What happens to the gas bubble after retina surgery?
Gas used in retina surgery does not have to be removed. It will absorb slowly on its own. A bubble of air consists mostly of nitrogen and oxygen with small amounts of argon and carbon dioxide. Air will absorb in 5 to 7 days.
What can you not do after a vitrectomy?

Como é feito o exame de descolamento da retina?
O médico examina a retina através de um oftalmoscópio e, geralmente, pode ver o descolamento após aplicar um colírio para dilatar a pupila. Se o descolamento não for visível, pode ser realizado um ultrassom do olho para que se torne mais evidente.
Quais são os fatores de risco de descolamentos regmatogênicos da retina?
Os fatores de risco de descolamentos regmatogênicos da retina são miopia, cirurgia prévia de catarata, trauma ocular, degeneração retiniana em treliça.
Como é feito o procedimento de tratamento da retina?
No procedimento, o médico removerá o vítreo — um fluído que preenche o interior do olho — e quaisquer outros tecidos que estejam impedindo a recuperação da retina. Ele então preencherá o olho com ar, gás ou líquido para substituir o vítreo, permitindo a fixação e a recuperação da retina.
Quais são os sintomas de descolamento rematogênico?
Os primeiros sintomas de descolamento rematogênico podem incluir moscas volantes vítreas escuras ou irregulares, particularmente uma aumento súbito de flashes de luz (fotopsias) e visão turva. Com a progressão do descolamento, o paciente frequentemente percebe uma cortina, véu ou acinzentado no campo de visão.
