A 30-year-old male, who underwent previous pars plana vitrectomy and silicone oil tamponade due to endogenous endophthalmitis originated from Klebsiella liver abscess, was referred for evisceration. At 2 months after vitrectomy with silicon oil tamponade, conjunctival chemosis and ocular pain were aggravated. Diffuse eyelid swelling and large subconjunctival mass with lipid droplets were noted. On MRI examination, subconjunctival mass and intra- and extraconal orbital mass around superior rectus muscle were observed. Excision of subconjunctival and orbital mass was performed. Histopathologic examination showed multiple silicone oil vacuoles surrounded by foreign body giant cells and fibrosis, which confirmed silicone oil granuloma. In a patient with suspicious melting sclera in diseases such as endophthalmitis, large silicone oil granuloma may be complicated in a rapid fashion after intravitreal silicone oil tamponade due to silicone oil leakage.

Purpose: To report the management and outcome of an unusual case of occupational perforating ocular industrial nail injury involving the posterior pole. Methods: Observational case report. A 48-year-old Chinese male construction worker presented with perforating industrial nail injury.Results: The patient underwent primary globe repair and foreign body removal followed by staged pars plana vitrectomy with endophotocoagulation and cyclopropane gas tamponade for repair of the vitreous incarceration at the posterior exit wound, a subsequent laser retinopexy with silicone oil tamponade for an inferior retinal detachment extending from the perforation site and finally silicone oil removal with a scleral fixated intraocular lens implant. His best-corrected visual acuity improved to 20/100 six months after the initial injury. Conclusion: Perforating ocular injuries involving the posterior pole often present with severe visual impairment and significant management challenges. We report a case of perforating ocular nail injury, which was managed successfully with staged surgical procedures.

A 7-year-old female presented with left upper eyelid swelling following pars plana deep vitrectomy and silicone oil injection 1 year before admission. The left upper eyelid had mechanical ptosis and on palpation there was a lobulated mobile mass in the lateral portion of eyelid. Computed topography scan showed multiple isodense masses with silicone oil in vitreous in the eyelid and orbit; histopathology after excisional biopsy proved the silicone oil migration. Silicone oil migration followed by vitrectomy may be due to leakage from the site of initial wounds or vitrectomy ports. It is important to suspect extraocular silicone oil migration in patients who presented with eyelid mass-like lesions with a history of silicone oil injection following pars plana deep vitrectomy.

Purpose To report the surgical success of vitrectomy with silicone oil tamponade in the treatment of retinal detachment associated with giant retinal tears due to various factors. Methods We retrospectively evaluated 21 eyes of 21 patients with retinal tears 90° or greater that underwent vitrectomy, with injection of perfluorocarbon liquids and silicone oil tamponade. Eight eyes (38.1%) had previous ocular surgery (4 aphakia-pseudophakia, 4 pars plana vitrectomy), 4 eyes (19.0%) had a history of trauma (blunt injuries in 2 and penetrating injury in 2), 3 (14.3%) had high myopia. Six eyes (28.6%) had no known condition predisposing to development of giant retinal tear. Results Retinal attachment was obtained in 17 (80.5%) of 21 eyes, with a mean follow-up of 12.5 months. Visual acuity improved in 15 eyes (71.4%). Conclusions Pars plana vitrectomy with silicone oil tamponade proved highly effective in giant retinal tears in terms of anatomical and functional results.

Introduction. To compare the effect and safety of intravitreal conbercept (IVC), intravitreal ranibizumab (IVR), or intravitreal triamcinolone acetonide (IVTA) injection on 23-gauge (23-G) pars plana vitrectomy (PPV) for proliferative diabetic retinopathy (PDR). Methods. Fifty patients (60 eyes) of varying degrees of PDR were randomly grouped into 3 groups (1 : 1 : 1) (n=20 in each group). The 23-G PPV was performed with intravitreal conbercept or ranibizumab injection 3–7 days before surgery or intravitreal TA injection during surgery. The experiment was randomized controlled, with a noninferiority limit of five letters. Main outcome measures included BCVA, operation time, incidence of iatrogenic retinal breaks, endodiathermy rate, and silicone oil tamponade. Results. At 6 months after surgery, there were no significant differences of BCVA improvements, operation time, incidence of iatrogenic retinal breaks, endodiathermy rate, silicone oil tamponade, vitreous clear-up time, and the incidence of intraoperative bleeding between the IVC and IVR groups (all P values ≥ 0.05), but they were significantly different from the IVTA group (all P values < 0.05). IOP increases did not show significant differences between the IVC and IVR groups, but both were significantly different with the IVTA group. More patients had higher postoperative IOP in the IVTA group. Conclusions. The intravitreal injection of conbercept, ranibizumab, or TA for PDR had a significant different effect on outcomes of 23-G PPV surgery. Conbercept and ranibizumab can reduce difficulty of the operation, improve the success rate of PPV surgery, and decrease the incidence of postoperative complications.

Purpose: To assess the safety and efficacy of hybrid vitreous surgery combining active 23-G ports with a sutured 20-G 6-mm infusion cannula for performing vitrectomy in endophthalmitis and trauma. Methods: This is a retrospective analysis of 10 eyes with endophthalmitis and 10 eyes with trauma requiring vitreous surgery, having corneal clarity suitable for vitrectomy and best-corrected visual acuity (BCVA) greater than or equal to light perception. All patients underwent hybrid 20/23-G vitrectomy. Intraoperative notes were analyzed for peroperative complications. The BCVA and retinal status at 3 months were analyzed. Results: In the endophthalmitis group, patients ranged from 5 to 85 years of age and showed varied etiologies. Retinal detachment was present in 5 eyes, which received silicone oil tamponade. Mean preoperative logMAR visual acuity (VA) was 2.29 ± 0.45, which improved to 1.10 ± 0.72 at 3 months postoperatively (p<0.001). Trauma cases ranged from 21 to 75 years of age. Retinal detachment was present in 9 out of 10 eyes, all of which received silicone oil tamponade. Preoperative logMAR VA was 2.26 ± 0.71, which improved to 1.33 ± 0.50 postoperatively (p<0.001). At 3 months postsurgery, the retina was attached in all eyes in both groups. Conclusions: The longer sutured 20-G cannula was easier to visualize through fibrin, exudates, and hemorrhage and did not slip out or enter the suprachoroidal space in any of our cases. The 23-G active ports and vitrectomy cutter enhanced safety and efficacy. Hybrid vitrectomy enabled safe surgery in these difficult cases.
