Summary
Drainage-retinotomies and relaxing retinectomies are safe in complex retinal detachment surgery. Angiography shows no significant damage to the attached retina, even in severe cases.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Vitreoretinal Surgery
Context:
- Extreme vitreoretinal surgery often requires advanced techniques like drainage-retinotomies and relaxing retinectomies.
- The pathophysiologic effects of these procedures on the retina, pigment epithelium, and choroid remain under-investigated.
Purpose:
- To investigate the pathophysiologic effects of drainage-retinotomies and relaxing retinectomies on the retina, pigment epithelium, and choroid using fluorescein angiography.
- To assess the safety and impact of these surgical techniques in patients with advanced proliferative vitreoretinopathy.
Summary:
- Fluorescein angiography of 30 patients undergoing retinotomies/retinectomies after vitrectomy for proliferative vitreoretinopathy revealed predominant endophotocoagulation effects with choriocapillaris occlusion and RPE changes.
- Retinal perfusion remained unaffected in treated and untreated areas, with no evidence of blood-retina barrier breakdown or ischemia.
- No significant reproliferations were observed at retinotomy/retinectomy sites; however, choroidal neovascular membranes can occur postoperatively, likely due to Bruch's membrane injury.
Impact:
- Angiographic findings support the clinical view that retinotomies and retinectomies, when used in otherwise untreatable cases, do not cause significant damage to the attached retina.
- These techniques are valuable surgical tools in complex vitreoretinal cases, with manageable risks and no significant adverse effects on retinal health.
