Summary
Secondary glaucoma is a common complication following pars plana vitrectomy with silicone oil injection, particularly in complex retinal detachment cases. This condition arises from silicone oil emulsification obstructing the trabecular meshwork.
Area of Science:
- Ophthalmology
- Retina Surgery
- Glaucoma Research
Background:
- Pars plana vitrectomy with silicone oil injection is a critical procedure for managing complex retinal detachments.
- Understanding post-operative complications, such as secondary glaucoma, is essential for patient management.
Purpose of the Study:
- To determine the prevalence of glaucoma after pars plana vitrectomy with silicone oil injection.
- To identify the clinical characteristics and forms of secondary glaucoma in this patient cohort.
Main Methods:
- Retrospective longitudinal study of 301 patients (301 eyes) who underwent pars plana vitrectomy with silicone oil injection between 1981 and 1995.
- Patients were treated for retinal detachment and proliferative vitreoretinopathy, with ages ranging from 8 to 85 years.
Main Results:
- The prevalence of secondary glaucoma was 18.5%.
- Glaucoma was consistently caused by trabecular meshwork obstruction due to silicone oil emulsification.
- Higher glaucoma incidence was observed in recurrent rhegmatogenous retinal detachment with fibrous proliferative vitreoretinopathy (52.86%) and specific rhegmatogenous retinal detachment forms (30%).
Conclusions:
- Secondary glaucoma is a frequent complication of intravitreal silicone oil injection for complicated retinal detachments.
- Procedures involving endophotocoagulation, endodiatermy, and lensectomy are associated with increased glaucoma risk.
