B-mode dynamic ultrasound of an eye with vitreous hemorrhage shows hyaloid traction inducing retinal detachment in diabetic retinopathy. The video clearly delineates all anatomical compartments: vitreous, subhyaloid, and subretinal spaces. Characteristic movement patterns are observed - the vitreous demonstrates smooth, wide excursions while the detached retina shows shorter, stiffer motions -confirming tractional pathology.

Condition/keywords: diabetic retinopathy, retinal detachment

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.

Condition/keywords: endophthalmitis

Color stills from surgical video after subretinal delivery of gene augmentation therapy with voretigene neparvovec-rzyl A) before and B) after fluid-air exchange (FAX). The blebs were between 0.5- and 1-disc diameters from the fovea. After FAX, they gradually extended beneath the fovea and eventually merged. This spared the fovea the trauma from the injection pressure of subretinal injection while allowing treatment to the area.

Color still from surgical video of subretinal delivery of laru-zova for X-linked retinitis pigmentosa. Live optical coherence tomography (OCT) with foveal tracking via the embedded software in the operating microscope allows monitoring foveal integrity for signs of stress. The contour of the fovea does not exceed the curvature of the bleb (e.g. no inversion). The tangential cannula angle facilitated steering of the bleb posteriorly. The bleb covers essentially the entire macula, which is the target area.

Color stills from surgical videos of subretinal delivery of gene augmentation therapy with A) voretigene neparvovec-ryzl and B) laru-zova. In the left panel, the cannula is slightly bent, and the retina and RPE are blanched white around the cannula tip engagement. The bleb was challenging to form in this patient with advanced retinal degeneration, and the bleb is shallow and mostly clear. In the right panel, the cannula tip is gently engaged, the cannula is straight, and it follows the retinotomy as the retina is elevated by the injection fluid.

The video demonstrates a surgical scenario where the fovea gives away by the force imparted by the jet of an injecting PFCL (Perfluorocarbon heavy Liquid) and the PFCL migrates subfoveally. Intraoperative OCT confirms the presence of a macular hole. The situation is managed by ILM peeling and mobilizing subfoveal PFCL peripherally by injecting another bubble of PFCL over the posterior pole. A peripheral drainage retinotomy is then created to aspirate the subretinal PFCL followed by fluid-air exchange, PFCL-air exchange, and endolaser around the retinotomy. Post-operative OCT at 3 weeks’ follow-up shows a sealed macular hole.

This is a case of Macular hole for which vitrectomy is being done. After doing core vitrectomy triamcinolone dye is injected to stain the hyaloid. High aspiration is used on cutter to engage the hyaloid and gradually pull it anteriorly. PVD induction is carried out. After this brilliant blue dye is injected to stain the internal limiting membrane. ILM is peeled using a 25 gauge forceps in a tangential manner. After this i use a instrument called the massager which we have developed to gently and atraumatically massage concentrically the edges of the hole. This releases the subtle contaction on the edges of the hole and relaxes the margins. After this air fluid exchange is carried out followed by low vacuum aspiration over the hole. The hole approximates itself gradually as the aspiration dries up the edges.

Vitrectomy for PDR and TRD and Vitreous haemorrhage using Cutter based dissection. The Vitreous haemorrhage is cleared first. A 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 is also used to gently peel off a adherent proliferation. Bleeders are stopped raising pressure and applying diathermy. Air fluid exchange is done and viscous subretinal fluid drained from a hole adjacent to diathermy superiorly. Once the retina is flattened endolaser is done 360 degree to achieve long term regression.

Vitrectomy for Myopic Retinal detachment with multiple tears and lattice degenerations | Vitrectomy is carried out and triamcinolone staining is used to stain the hyaloid attachment. The hyaloid attachment is extremely adherent. With high vacuum the cutter engages the stained hyaloid and gradually peels it off the mobile retina. After this Perfluorocarbon heavy liquid is injected to flatten the posterior pole and push the fluid to the periphery till the edge of the tear. This is followed by endo drainage from the tear. Once the retina flattened endolaser was carried out.

This is a case of non resolving ILM hemorrhage over macula. Vitrectomy is carried out and hyaloid is removed after traimcinolone staining. After this brilliant blue dye is injected to stain the ILM. Internal limiting membrane is then removed with a forceps. Once the sub ilm blood is exposed , it easily aspirates with the cutter. The origin is probably from a macroaneurysm and there is a small component of subretinal residual blood noted at the end of the surgery.

This is a case of non resolving ILM haemorrhage over macula. Vitrectomy is carried out and hyaloid is removed. Cutter is used to try to aspirate the blood from the surface of macula. But due to its location in the sub ILM space i use a forceps to make a opening in the ILM. Through the opening the blood aspirates easily.
