A retrospective case series highlights two cases of postoperative endophthalmitis, in which similar improper technique of puncturing the antibiotic bottle with a nonsterile needle was noted. Patient A, a 65-year-old man with three weeks’ history of uneventful combined cataract and pars plana vitrectomy (PPV) presented with acute painful right eye and vision blurring from 6/12 to 1/60 for two days. Examination showed severe anterior chamber activity and hazy fundal view. B-scan showed dense vitritis. Vitreous sampling revealed gram positive cocci, but no culture growth. Patient B, a 69-year-old man presented with three days’ history of right painful red eye and vision dropped to light perception following an uneventful cataract surgery. Examination showed severe anterior chamber activity with hypopyon, raised intraocular pressure, and no fundal view. B-scan detected dense vitritis with loculation. Vitreous sampling cultured Pseudomonas aeruginosa in Patient B. In both cases, the patients reported piercing the generic topical ciprofloxacin 0.3% bottle tip with a nonsterile needle instead of the prescribed method of using the sterile, inner aspect of the bottle cap. However, the cultures of the bottle contents were negative in both cases. Both patients received intravitreal, topical, and systemic antibiotics and subsequently underwent PPV. Patient A recovered vision to baseline, while Patient B recovered to counting finger vision. The cap-puncturing mechanism for eye drop bottles is designed to maintain the sterility of the contents. However, this may backfire when patients do not understand the prescribed technique. We postulate that this improper technique predisposed the two cases to endophthalmitis.

Background: The incidence rate of venous thrombotic events (VTEs) following foot and ankle surgery is low. Currently, there is no consensus regarding postoperative prophylaxis or evidence to support risk stratification. Methods: A 2-part study assessing the incidence and factors for the development of VTE was conducted: (1) a retrospective observational cohort study of 22 486 adults to calculate the overall incidence following foot and/or ankle surgery from January 2008 to May 2011 and (2) a retrospective matched case-control study to identify risk factors for development of VTE postsurgery. One control per VTE case matched on age and sex was randomly selected from the remaining patients. Results: The overall incidence of VTE was 0.9%. Predictive risk factors in bivariate analyses included obesity, history of VTE, history of trauma, use of hormonal replacement or oral contraception therapy, anatomic location of surgery, procedure duration 60 minutes or more, general anesthesia, postoperative nonweightbearing immobilization greater than 2 weeks, and use of anticoagulation. When significant variables from bivariate analyses were placed into the multivariable regression model, 4 remained statistically significant: adjusted odds ratio (aOR) for obesity, 6.1; history of VTE, 15.7; use of hormone replacement therapy, 8.9; and postoperative nonweightbearing immobilization greater than 2 weeks, 9.0. The risk of VTE increased significantly with 3 or more risk factors ( P = .001). Conclusion: The overall low incidence of VTE following foot and ankle surgery does not support routine prophylaxis for all patients. Among patients with 3 or more risk factors, the use of chemoprophylaxis may be warranted. Level of Evidence: Level III, retrospective case series.

A 49-year-old gentleman presented with a 1-day history of painful deterioration of vision in his right eye. He was lifting heavy weights just before this visual loss. On examination, his vision was perception of light in that eye, with a medically uncontrollable high intraocular pressure and hyphaema almost completely filling his anterior chamber. An ultrasound performed suggested a working diagnosis of a Valsalva related ‘eight ball’ bleed. After an anterior chamber washout, he had another episode of bleeding three days later. A pars plana vitrectomy was performed and the sample obtained was sent off to the laboratory, revealing a choroidal melanoma. Following enucleation, the histology confirmed a large necrotic spindle cell melanoma, with a haemorrhagic background. Fortunately, no liver metastasis was found. Since his diagnosis 3 years ago, he continues to be followed up in an artificial eye clinic and has regular liver scans under the care of his oncologist.

ObjectiveIntraocular lens (IOL) repositioning using a closed-eye approach could be carried out in some selected cases. Our study focuses on the efficacy and safety of a IOL closed-eye repositioning technique using scleral suture, which is performed using a trocar as an intrastromal limbal guide.Methods and analysisThirty-one eyes of 31 patients with late IOL dislocation operated on between January 2015 and May 2017 were included in this retrospective non-comparative consecutive case series study. The patients had a single-piece in-the-bag dislocation or a 3-pieces in-the-bag or out-of-the-bag dislocation. The patients underwent an anterior vitrectomy and a scleral refixation in a closed chamber using a 10/0 polypropylene suture passed through a 25 Gauge trocar inserted in the anterior chamber.ResultsThe mean follow-up time was 19.54 months. Average preoperative best-corrected visual acuity (BCVA) was 0.73 LogMar (±0.21 SD); while average postoperative BCVA was 0.27 LogMar (±0.23 SD). Fifteen patients underwent anterior pars plana vitrectomy (PPV) while 16 patients did not; moreover, two patients underwent PPV. Six patients had an increase of postoperative intraocular pressure, two patients had postoperative decentration, two patients had postoperative cystoid macular oedema, none of the patients had major complications such as retinal detachment, choroidal detachment, malignant glaucoma, irreversible corneal decompensation and endophthalmitis.ConclusionWe can affirm that our technique may be safe and useful in the case of 3-piece in-the bag or out-of the bag dislocated IOLs and also in the case of in-the-bag single-piece dislocated IOLs.

Abstract Background: The purpose of this study is to report the safety and efficacy of pars plana (PP) glaucoma drainage devices (GDDs) with pars plana vitrectomy (PPV) using one of the vitrectomy sclerotomy sites for tube placement in patients with refractory glaucoma.Methods: Retrospective case series of 28 eyes of 28 patients who underwent combined PP GDD and PPV between November 2016 and September 2019 at Massachusetts Eye and Ear. Main outcome measures were intraocular pressure (IOP), glaucoma medication burden, best corrected visual acuity (BCVA), and complications. Statistical tests were performed with R and included Kaplan-Meier analyses, Wilcoxon paired signed-rank tests, and Fisher tests.Results: Mean IOP decreased from 22.8 mmHg to 11.4 mmHg at 1.5 years (p = 0.009), and mean medication burden decreased from 4.3 to 1.7 at 1.5 years (p = 0.009). Both IOP and medication burden were significantly lower at all follow-up time points. The probability of achieving 5 ≤ IOP ≤ 18 mmHg with at least 20% IOP reduction from preoperative levels was 77.7% at 1 year and 45.8% at 1.5 years. At their last visit, four eyes (14.3%) achieved complete success with IOP reduction as above without medications, and 13 eyes (46.2%) achieved qualified success with medications. Visual acuity was unchanged or improved in 23 eyes (82.1%) at their last follow-up. Two patients had a visual acuity decrease of >2 lines. Two eyes required subsequent PPV for tube obstruction, and one eye had transient hypotony.Conclusions: The results of pars plana GDD and vitrectomy using one of the vitrectomy sclerotomy sites for tube placement are promising, resulting in significant IOP and medication-burden reductions through postoperative year 1.5 without additional risk of postoperative complications. Inserting GDDs into an existing vitrectomy sclerotomy site may potentially save surgical time by obviating the need to create another sclerotomy for tube placement and suture one of the vitrectomy ports.

Efficacy Outcome

ObjectiveTo evaluate the efficacy of an anterior chamber intracameral dexamethasone (ICD) drug-delivery suspension (Dexycu; EyePoint Pharmaceuticals, Watertown, Massachusetts, USA) providing sustained release of medication following a single application for the treatment of postoperative inflammation in patients undergoing vitreoretinal surgery compared to daily postoperative treatment with topical corticosteroids for up to 1 month.Methods and analysisRetrospective case-matched comparison of patients undergoing initial vitreoretinal surgery by a single surgeon. Patients had a preoperative best-corrected visual acuity of 20/20 to light perception and a variety of vitreoretinal pathologies. 27 eyes of 27 patients received ICD at the time of surgery and were compared with 27 eyes of 27 patients who received daily postoperative corticosteroid eye drops over 4 weeks. The primary efficacy outcome was anterior chamber cell (ACC) clearing (0 cells) in the study eye at postoperative day (POD) 7. Ocular adverse events were assessed through POD 90.ResultsACC clearing at POD 7 was achieved in 67% of eyes in the ICD treatment group and 37% of eyes in the control group treated with topical corticosteroids (p=0.029). No serious ocular adverse events were noted up to POD 90 in either group.ConclusionThe ICD drug-delivery suspension placed in the anterior chamber after vitreoretinal surgery was more effective than topical corticosteroids in treating inflammation occurring 1 week following vitreoretinal surgery and thus may be an alternative to daily corticosteroid drop installation in this patient population.

This study is for reporting the outcomes of internal limiting membrane (ILM) peeling on persistent submacular fluid (PSF) after otherwise successful pars plana vitrectomy (PPV) for diabetic tractional retinal detachment (TRD). In this retrospective case series, five consecutive patients (5 eyes) who exhibited PSF following successful repair of diabetic TRD were included. The second operation was performed to remove ILM. The area of ILM peeling was expanded up to the major vascular arcade. Only air tamponade was used. The median interval between the first PPV and the second PPV with ILM peeling was 4.8 months (range: 4–6 months). PSF resolved completely within one (2 eyes) or 2 months after ILM peeling. The median logMAR best-corrected visual acuity (BCVA) was improved from 1.00 (Snellen equivalent 20/200) to 0.70 (Snellen equivalent 20/100). In conclusion, wide ILM peeling is an effective treatment option for PSF subsequent to successful repair of diabetic TRD. ILM peeling might increase the elasticity of retina, thereby allowing the retina to flatten. This procedure can induce faster retinal reattachment in diabetic TRD involving the macula.

Abstract Background: The natural history of traumatic femur head necrosis (TFHN) after femoral neck fracture (FNF) in children and adolescent is relatively unknown and has never been specifically characterized. As we speculated, the natural history in such population would be poor and characterized as the high risk of femoral head collapse, hip deformity and degeneration in a short term. Methods: This retrospective case series enrolled 64 children and adolescent with TFHN who treated with observational treatment from 2000.1 to 2018.1. The primary outcomes, such as the progression of femoral head collapse, hip deformity (Stulberg classification) and hip degeneration (Tönnis grade), and their prognostic factors were analysed. Results: 42 males and 22 females with a mean age of 13 years (6-16 years), were included. A total of 28 hips (44%) showed unsatisfactory outcome and Twenty-five (39%) hips collapsed progressively during a mean follow-up of 48 months (24-203 months). Finally, 38 hips (59%) experienced hip deformity, 20 of them were class IV/V. 34 hips (53%) generally progressed to osteoarthritis, 14 of them were classified as grades II/III. The location of the lesion and the presence of lateral subluxation were found to be independently related to progression of femoral head collapse; however, the presence of lateral subluxation was the only independent risk factor of severe hip deformity and degeneration. Conclusion: TFHN in children and adolescent is a rapidly progressing disease with a poor natural history characterized by a high risk of femoral head collapse progression. If the lateral subluxation emerged, collapsed cases showed increasingly tendency towards severe hip deformity and degeneration.

Abstract Background: This study aimed to determine the efficacy and complications of intravitreal chemotherapy-assisted endoresection for refractory International Classification of Retinoblastoma (ICRB) group D retinoblastoma in monocular patients.Methods: In this retrospective case series, intravitreal chemotherapy-assisted endoresection by pars plana vitrectomy was performed in 11 eyes with refractory ICRB group D retinoblastoma unresponsive to standard therapies in monocular patients.Results: Across a mean follow-up period of 42.7 months, globe salvage was attained in all 11 eyes (100%). There were no cases of extra-ocular tumour seeding or remote metastasis. In 9 eyes (81.8%), tumour control was achieved with one pars plana vitrectomy; in 2 cases (18.2%), repeated treatment, such as laser therapy, intravitreal chemotherapy or a second pars plana vitrectomy, was needed. Retinal reattachment was achieved in all 4 eyes (100%) with previous retinal detachment. Four eyes (36.4%) required subsequent cataract surgery due to secondary cataract. Ten eyes (90.9%) had improvement in best-corrected visual acuity at the last follow-up.Conclusion: Intravitreal chemotherapy-assisted endoresection appears to be a safe and effective globe-salvaging method for refractory group D retinoblastoma. It is a promising alternative to enucleation and a supplementary therapeutic strategy for those unresponsive to standard therapies, especially for the monocular retinoblastoma patients.

Abstract Background To review the clinical features, radiographic features, therapy, pathological features and prognosis of orbital cholesterol granuloma(CG). Methods Twelve patients with orbital CG who were referred to Tianjin Eye Hospital between January 2002 and December 2020 were include in this retrospective case series study. Data collected included patient ophthalmic manifestations, imaging finding, treatment strategies, pathological features and prognosis were retrospectively reviewed. Results The patients comprised 10 males and 2 females. The mean age was 34.5±8.9 years(range 16 to 45 years). Four patients had a history of orbital trauma. The clinical manifestations at first visit were proptosis ( 7/12, 58.3%), periorbital or eyelids swelling (6/12,50%), limitation of eye displacement (4/12,33.3%), ptosis(2/12,16.7%), decreased visual acuity (1/12,8.3%).CT showed a non-enhancing,well-circumscribed lesion in the orbit with extensive erosion of the adjacent frontal bone and temporal bone.MRI showed a non-enhancing mass with intermediate to high signal intensity on T1- and T2-weighted imaging. Ten patients underwent lateral orbitotomy, and two patient underwent supraorbital orbitotomy,.All patients had aggressive bone erosion. Histopathologic evaluation of the cyst contents and wall revealed cholesterol clefts,multinucleated giant cells,histiocytes, foamy macrophages,and altered blood pigments. The median recurrence time of 79.6±49.8 months (range 19 month to 193 months). Three patients were lost to follow-up. No postoperative diminution of vision was noted,and no recurrence was observed. Conclusions Cholesterol granulomas can present as superiotemporal or temporal orbital lesions. The diagnosis can be established based on CT and MRI. Most of patients can have no history of orbital trauma.
