This set of four wide-field fundus photographs (labeled A-D) illustrates the progression and surgical management of Acute Retinal Necrosis (ARN) complicated by Rhegmatogenous Retinal Detachment (RRD) and Proliferative Vitreoretinopathy (PVR). Image A shows significant vitreous haze and opacity (vitritis) typical of early ARN, obscuring the posterior pole. Image B, following pars plana vitrectomy (PPV) and silicone oil tamponade, reveals widespread retinal necrosis and significant retinal vascular occlusion (vasculitis). Image C displays the fundus after silicone oil removal, characterized by severe inferior retinal detachment with extensive PVR, visible tractional bands, and retinal holes. Image D demonstrates the postoperative result after a second vitrectomy, showing a reattached, flat retina with residual peripheral proliferation and pigmentary changes from prior laser photocoagulation. This comparison highlights common complications of ARN, including PVR-induced tractional detachment following surgical intervention.

This composite educational resource illustrates clinical and demographic aspects of Proliferative Vitreoretinopathy (PVR). Panel A shows a color fundus photograph of a human eye with severe PVR, characterized by vitreous opacification, visible epiretinal fibrous proliferation, and radial star folds causing significant retinal distortion. Panel B presents a corresponding B-scan ultrasonogram (diagnostic ultrasound) of the posterior segment, demonstrating high-amplitude echoing from thick preretinal membranes and a characteristic funnel-shaped tractional retinal detachment (closed configuration). Panel C provides a patient demographics table correlating sex, age, and clinical diagnosis (Retinal Detachment [RD], Epiretinal Membrane [ERM], or Macular Hole [MH]) with PVR severity levels (None, Mild, Severe) and exosome particle concentrations. The image serves to teach the correlation between clinical presentation, imaging findings, and laboratory biomarkers in advanced vitreoretinal disease.

This color fundus photograph of a left eye demonstrates severe ocular pathology, characterized by total retinal detachment and advanced proliferative vitreoretinopathy (PVR). The retinal tissue exhibits a significant loss of normal transparency, appearing opaque, pale, and thickened with prominent corrugations and folds. The normal red-orange fundus reflex is obscured by this elevated, fibrotic tissue. Central and posterior regions show extensive tractional changes and epiretinal membrane contraction, which distort the normal vascular architecture and completely obscure the macula and foveal landmarks. Tortuous retinal vessels are visible on the surface of the detached retina, some showing signs of displacement. The overall clinical picture represents an end-stage manifestation of complex retinal disease, such as X-linked retinoschisis complicated by chronic rhegmatogenous retinal detachment and failed surgical repairs. This image serves as a clinical example of Grade C or D PVR where intraocular scarring has led to profound structural distortion and total detachment.

This clinical diagnostic image is a preoperative fundus photograph of the left eye in a patient with Stickler syndrome. The image demonstrates a rhegmatogenous retinal detachment associated with Grade C2 proliferative vitreoretinopathy (PVR). The retinal surface exhibits a hazy, mottled texture with a characteristic bluish-green hue and increased reflectivity, particularly in the superior quadrants, indicative of retinal folds and subretinal fluid accumulation. There is a notable lack of distinct retinal vasculature due to the significant vitreous opacity and membranous changes in the periphery. A central reddish-brown area is visible, suggesting a region of significant retinal thinning or a retinal hole that allows for visualization of the underlying choroidal pigment. The overall appearance captures the chronic nature of the detachment with irregular contours and evidence of contractile PVR membranes that distort the normal anatomical landmarks of the posterior pole.

This set of four fundus images (a-d) illustrates the clinical progression of proliferative vitreoretinopathy (PVR) or proliferative diabetic retinopathy over time. Image (a) shows early signs of neovascularization, with fibrovascular proliferation (arrow) near the superior vascular arch. Image (b) demonstrates rapid advancement 4 weeks later, with increased proliferation (arrows) and new retinal hemorrhages (arrowheads). Image (c) displays a severe complication at 9 weeks, characterized by tractional retinal detachment (TRD) and extensive vitreous hemorrhage, obscuring macular details. Image (d) shows the postoperative appearance after vitrectomy, indicating retinal reattachment but significant architectural distortion. The series serves as an educational timeline for medical professionals to identify early vascular proliferation and the catastrophic risks of progression to tractional detachment. Key educational concepts include neovascularization, fibrovascular membranes, vitreoretinal traction, and surgical intervention in advanced retinopathy.

This clinical diagnostic image is an intraoperative fundus photograph demonstrating a rhegmatogenous retinal detachment (RRD) with a significant primary pathology highlighted. Encircled in black is a large, irregularly shaped retinal tear. The defect appears as a well-defined, bright discontinuity in the retinal tissue, revealing the underlying reddish-orange choroid. Associated with this tear is evidence of incarcerated vitreous, appearing as a focal point of traction. The surrounding retina is diffusely pale, opaque, and elevated, characteristic of a bullous retinal detachment. Subtle haziness across the posterior segment suggests subretinal fluid accumulation and mild proliferative vitreoretinopathy (PVR) changes. The imaging illustrates the critical relationship between a full-thickness retinal break and the subsequent development of extensive detachment. This visual is highly relevant for ophthalmology training, specifically in identifying surgical landmarks during pars plana vitrectomy for complex retinal repairs.
