Early anterior segment complications after silicone oil injection

Area of Science:

• Ophthalmology
• Retinal Surgery
• Vitreoretinal Diseases

Background:

• Silicone oil injection is a common tamponade agent for vitreoretinal surgery.
• Complications associated with silicone oil can impact visual outcomes.
• Understanding these complications is crucial for patient management.

Purpose of the Study:

• To evaluate the incidence and types of complications following silicone oil injection in different patient groups.
• To identify risk factors associated with silicone oil-induced complications.

Main Methods:

• Retrospective analysis of 45 patients undergoing silicone oil injection for vitreoretinal problems.
• Patients categorized into three groups: aphakic extracapsular cataract extraction (AEC), aphakic intracapsular cataract extraction (AIC), and phakic (PHA).
• Follow-up duration ranged from 4 to 13 months (average 8.5 months).

Main Results:

• Irreversible silicone keratopathy occurred in 50% of AIC eyes within 4-8 weeks postoperatively.
• An intact lens or capsule was associated with a lower risk of silicone keratopathy.
• Secondary cataract was the most prominent early complication in 60% of phakic eyes by 8 weeks.
• Other complications included inflammatory membranes, rubeosis, iritis, glaucoma, and capsular opacification.

Conclusions:

• Silicone oil-induced keratopathy is a significant risk in aphakic patients post-intracapsular cataract extraction.
• Phakic eyes are prone to early secondary cataract formation after silicone oil injection.
• Careful patient selection and monitoring are essential to mitigate silicone oil-related complications.
