B-mode ultrasound video of a vitrectomized eye reveals characteristic vitreous cavity membranes secondary to endophthalmitis. The real-time imaging demonstrates these inflammatory membranes exhibit semi-rigid dynamics, displaying viscoelastic behavior with limited displacement during ocular movements while maintaining structural integrity. This restricted mobility pattern, showing both resistance to kinetic forces and slow recoil, represents a pathognomonic feature of advanced fibrotic organization in endophthalmitis.

Optomap RGB montage of an 64-year-old woman with a repaired retinal detachment with scleral buckle in the right eye. There is nasal and inferior pre-retinal membranes with traction. PPV was recommended but patient defers to proceed with sx at this time. Will continue to follow patient closely for worsening traction. Patient was educated on how to monitor their peripheral vision and was advised to report any changes immediately.

A fundus photograph of a 28-year-old male monocular patient diagnosed with proliferative diabetic retinopathy, who is highly motivated to pursue retinal surgery. This case presents a unique challenge in both management and communication, given the patient's strong desire for intervention and the guarded prognosis for visual improvement.

Cases of proliferative diabetic retinopathy with fibrovascular membranes are among the most complex in retinal surgery. Here are 10 steps I follow in each case to achieve the best possible outcome, particularly when performing one-handed dissection with the vitrector.

We present a case of a 20-year-old patient who underwent surgery for congenital cataract when he was born and 20 years after he developed a retinal detachment with proliferative vitreoretinopathy. Proliferative vitreoretinopathy (PVR), a major complication of rhegmatogenous retinal detachment (RRD), is an abnormal process whereby proliferative, contractile cellular membranes form in the vitreous and on both sides of the retina, resulting in tractional retinal detachment with fixed retinal folds. PVR arises in an estimated 5-10% of RRD cases, and therefore represents a major complication of retinal detachment. The best treatment of PVR is its prevention. Clinical factors associated with increased risk of PVR include: • Chronic RRD • 2 o more horseshoe retinal tears and RRD exposing three-disc diameters or more of RPE • RD associated with giant retinal • RD associated with choroidal detachment • Ocular Trauma • RRD associated with vitreous hemorrhage • Aphakia and RRD • Failure of previous surgery or multiple retinal surgeries • Aggressive retinitis, etc.

Color fundus photograph of the left eye of a 70-year-old male with a disciform scar resulting from a neovascular membrane. A minority of MacTel type 2 patients develop neovascular disease, and the gold standard treatment is anti-VEGF intravitreal therapy. Without treatment, membranes may progress to severe central macular scarring. Late stages of proliferative MacTel type 2 may be confused with AMD, and a differentiating aspect is that MacTel type 2 typically lacks pigment epithelial detachments and drusen.

A 58-year-old female underwent phacovitrectomy + scleral buckling by retinal detachment. Silicon oil was used as endo tamponade. In the post-surgical period, the formation of a subretinal PRV is observed with a significant circumferential contraction that generates an inferior redetachment. It was decided to undergo a vitreous cavity lavage to remove membranes + 180° retinectomy.

Anterior segment photography of a 54-year-old woman with post phacoemulsification endophthalmitis. She did not improve after first intravitreal antibiotics injection and develop an inflammatory pupillary membrane. After two vitrectomies, and a complete three intravitreal injections scheme, we decided to remove the intraocular lens and capsules.

Vitrectomy for PDR and TRD using Cutter based dissection| This is a case of subhyaloid hemorrhage and Tractional retinal detachment in a diabetic patient. The subhyaloid hemorrhage is aspirated using the cutter . 25 gauge bevelled cutter is used to dissect all the epiretinal proliferations and tractional components. The ports of these cutters can reach very close to the retinal surface and cut flush without causing any iatrogenic damage to the retinal surface. Forceps are used to peel adherent membranes Bleeders are stopped raising pressure and applying diathermy. Once the retina is flattened endolaser is done 360 degree to achieve long term regression.

This is the results at 6 months of a Bimanual 23 G-PPV with a very extensive and posterior 360 retinotomy for the management of a combined longstanding closed funnel RD, with submacular membranes, intraretinal PVR. Preop VA was a doubtful light perception. Borders of the retinotomy are stable at 6 months under 1300 Cs Silicon oil with some pigmented PVR developping the edges. Macula appears spared. Silicon oil emulsification droplets are well visualized beneath the superior temporal arcade.

Immunohistochemistry of a human fetal eye after invagination of the optic vesicle demonstrates basement membrane staining with fluorescein conjugated ABA lectin staining. Continuity of the membranes destined to be Bruch’s membrane and the Inner Limiting Membrane (ILM) of the retina is evident (see loops at upper aspects of this image), suggesting a common embryologic origin and similar composition. Thus, there may be important similarities during pathologies (especially neovascularization) at these two interfaces, which may provide insights into the process of pathologic cell migration and proliferation. Anterior to the ILM and behind the lens is the vascular primary vitreous. [Cover Photo - Sebag J and Hageman G: Interfaces.
