[[Vitrectomy]] is a surgical procedure used to treat complicated retinal detachments.<ref name=":1" /> It is especially useful for large retinal tears or tears that are not easily visible.<ref name=":1" /> Vitrectomy is also used for [[proliferative vitreoretinopathy]], which is the growth of scar tissue on the retina that can occur after a retinal detachment.<ref name=":1" /><ref>{{Cite web |title=Complex Retinal Detachment - Patients - The American Society of Retina Specialists |url=https://www.asrs.org/patients/retinal-diseases/34/complex-retinal-detachment |access-date=2024-12-08 |website=www.asrs.org}}</ref><ref>{{Cite journal |last1=Idrees |first1=Sana |last2=Sridhar |first2=Jayanth |last3=Kuriyan |first3=Ajay E. |date=2019 |title=Proliferative Vitreoretinopathy: A Review |journal=International Ophthalmology Clinics |volume=59 |issue=1 |pages=221–240 |doi=10.1097/IIO.0000000000000258 |issn=1536-9617 |pmc=6310037 |pmid=30585928}}</ref> In this technique, the vitreous gel is removed from the eye to relieve the pulling force on the retina.<ref name=":1" /><ref name=":7" /> Any fluid behind the retina is drained, and tears are sealed with freezing or lasers.<ref name=":1" /><ref name=":7" /> The removed vitreous is then replaced with either a gas bubble or [[silicone oil]], which stabilizes the retina.<ref name=":1" /><ref name=":7" /><ref name=":14">{{Cite web |title=Vitrectomy {{!}} National Eye Institute |url=https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/retinal-detachment/vitrectomy |access-date=2024-12-08 |website=www.nei.nih.gov}}</ref> Patients treated with a gas bubble are advised to maintain a face-down position and refrain from air travel, high altitudes, and scuba diving.<ref name=":1" /><ref name=":7" /><ref name=":14" /><ref name=":15">{{Cite web |date=2024-10-01 |title=What Is Vitrectomy? |url=https://www.aao.org/eye-health/treatments/what-is-vitrectomy |access-date=2024-12-08 |website=American Academy of Ophthalmology |language=en}}</ref> In patients treated with silicone oil, a follow-up surgery is required to remove the oil.<ref name=":1" /><ref name=":7" /><ref name=":15" />  For patients who have not previously undergone [[cataract surgery]], vitrectomy increases the risk of developing a [[cataract]] in the treated eye.<ref name=":1" /><ref name=":7" /><ref name=":15" />
