Risk factors for proliferative vitreoretinopathy.

Area of Science:

• Ophthalmology
• Retinal Diseases
• Vitreoretinal Surgery

Background:

• Proliferative vitreoretinopathy (PVR) remains a significant challenge in vitreous surgery, often leading to poor visual prognosis even after successful retinal reattachment.
• The precise mechanisms and risk factors contributing to PVR development require further elucidation to optimize treatment strategies.

Purpose of the Study:

• To review the current understanding of PVR pathogenesis.
• To identify and summarize key clinical risk factors associated with PVR development.
• To discuss current medical treatment approaches for PVR.

Main Methods:

• Literature review of studies on proliferative vitreoretinopathy.
• Synthesis of information on PVR pathogenesis, clinical risk factors, and treatment.

Main Results:

• Retinal breaks and blood-retinal barrier breakdown are essential prerequisites for PVR development.
• Identified risk factors are predominantly linked to intravitreal dispersion of retinal pigment epithelial cells or compromised blood-retinal barrier.

Conclusions:

• Understanding PVR pathogenesis and risk factors is vital for managing rhegmatogeneous retinal detachment.
• Clinical risk factor identification offers guidelines for improved patient management and treatment planning in PVR cases.
