Silicone Oil

A research letter published in JAMA Ophthalmology described the case of a patient with geographic atrophy who reported multiple small floaters after intravitreal injection of pegcetacoplan.

SEATTLE — Cases of unexplained vision loss following silicone oil tamponade removal have been reported over the years. Potential causes have been investigated but remain unclear.

FORT LAUDERDALE, Fla. — Recurrent retinal detachment can occur after silicone oil removal following retinal detachment surgery. A study investigating risk factors found previous silicone oil exchange as the only significant association.

WAIKOLOA, Hawaii — Recurrent retinal detachment with proliferative vitreoretinopathy can be effectively managed by vitrectomy, membrane peeling, retinectomy, laser and silicone oil, with the oil then removed 3 to 4 months later.

Welcome to another edition of CEDARS/ASPENS Debates. CEDARS/ASPENS is a society of cornea, cataract and refractive surgery specialists, here to discuss some of the latest hot topics in ophthalmology.

In conjunction with the annual ASRS Preferences and Trends survey, retina specialists in Asia-Pacific, Africa and Middle East, Central-South America and Europe were invited to participate in the Global Trends in Retina Survey.

In any eye with a history of retinal surgery, it is important to obtain medical records to determine whether a gas bubble or silicone oil was placed during the vitrectomy because these can have different implications for cataract surgery.

Silicone oil-induced glaucoma is associated with raised IOP that is often unresponsive to a medical line of management. Removal of silicone oil from the eye has to be weighed against the repercussions of retaining it inside the eye.

Secondary angle closure due to any mechanism compromises the normal aqueous outflow route and results in secondary elevation of IOP. Left uncorrected, over time this can cause optic nerve damage and possible permanent vision loss. When medical avenues are ineffective in opening the angle, surgical intervention to either open the closed angle or provide an alternate route of aqueous egress is essential to prevent potential vision loss.

Intracameral platelet-rich plasma injected into the anterior chamber can treat cases of chronic hypotony that are nonresponsive to other treatment options, according to Jorge L. Alió, MD, PhD.
