PURPOSE: To present a rare case of bilateral endogenous chorioretinitis and unilateral endophthalmitis due to Mycobacterium bovis in a patient who received intravesical bacillus Calmette-Guerin (BCG) treatment. METHODS: We present a case of a single male patient with bilateral endogenous chorioretinitis due to Mycobacterium bovis in a patient who received intravesical BCG, an attenuated strain of M. bovis widely used to treat superficial bladder cancer. The patient underwent intravitreal tap, vitrectomy, and chorioretinal biopsy with histologic examination...

A 55-year-old nurse was referred with a 5-month history of right eye corneal abscess. The initial injury occurred when doing lawn work. The infection worsened despite multiple antibiotic, antiviral, and steroid treatments. Visual acuity was limited to hand motion. On examination, there was keratitis, ocular hypertension, and a secondary cataract. Corneal scrapings grew a filamentous fungus, identified as Metarhizium anisopliae (MA). Despite intensive antifungal treatment with topical, intravitreous, and systemic voriconazole, purulent corneal melting and scleritis with endophthalmitis rapidly appeared...

PURPOSE: To investigate the use of 27-gauge pars plana vitrectomy (PPV) with short-term tamponade of perfluorocarbon liquid (PFCL) for repair of giant retinal tears (GRT). METHODS: Retrospective case series study. Consecutive patients with GRT were treated with 27-gauge PPV and short-term tamponade of PFCL for 7-10 days. PFCL was completely removed with a secondary surgery. RESULTS: Twenty-three eyes of 23 patients were included. All the patients achieved primary anatomic success...

PURPOSE: This study aims to evaluate and correlate the levels of interleukin-6 (IL-6) and thrombin-antithrombin III complex (TAT) in the vitreous of patients with different vitreoretinal pathologies. METHODS: Vitreous samples were collected from 78 patients scheduled for pars plana vitrectomy at a tertiary medical center. Patients were divided by the underlying vitreoretinal pathophysiology, as follows: macular hole (MH)/epiretinal membrane (ERM) (n = 26); rhegmatogenous retinal detachment (RRD) (n = 32); and proliferative diabetic retinopathy (PDR) (n = 20)...

PURPOSE: To assess the surgical and functional outcome of internal direct cyclopexy as therapy of complicated traumatic cyclodialysis. METHODS: The single-centre interventional case-series study included eyes with traumatic cyclodialysis who had consecutively been treated. Internal cyclopexy was performed using double-armed sutures introduced into the eye through the pars plana opposite to the cyclodialysis cleft and which were laid parallel to limbus. Additional procedures included cataract surgery, and pars plana vitrectomy...

PURPOSE: To evaluate superficial capillary plexus (SCP) changes occurring after internal limiting membrane (ILM) peeling for the treatment of idiopathic epiretinal membrane (ERM). METHODS: A total of 15 eyes of 15 patients affected by idiopathic ERM (eight males and seven females; mean age 59.8 ± 9.6 years) were enrolled in the study. Patients were treated with pars plana vitrectomy followed by ERM and ILM peeling. Subjects were evaluated at baseline and at the week-1 and month-1 follow-up visits...

BACKGROUND: To report a case of metastatic hepatocholangiocarcinoma to the vitreous and retina. CASE PRESENTATION: A 70-year-old male, who was recently diagnosed with hepatocholangiocarcinoma, was complaining of floaters in his right eye over the past 5 months and was referred to the Liverpool Ocular Oncology Centre. On presentation, his visual acuity in the right eye was 6/24. Fundus exam revealed a whitish, unilateral, full-thickness retinal lesion at the inferotemporal arcade of his right eye, with vitreous infiltration and subretinal fluid...

PURPOSE: To compare subconjunctival scarring after vitrectomy in rabbit eyes using different gauge systems by analysing anterior segment optical coherence tomography (AS-OCT) images and histological sections. METHODS: Vitrectomy using 20-, 23-, 25- and 27-gauge systems was performed for rabbits. Anterior segment optical coherence tomography (AS-OCT) images of the incision sites were obtained before and at day 1, 7 and 1 month after surgery. We measured the thickness of conjunctival epithelium, stroma, Tenon's capsule and total conjunctiva of these three layers, then determined the preservation rates of the borderlines between each layer...

PURPOSE: We report a case of rapid cataract progression after Nd:YAG vitreolysis for vitreous floaters. CASE REPORT: A 55-year-old man presented with acute onset of blurred vision following Nd:YAG vitreolysis for symptomatic floaters in the left eye. His initial best corrected visual acuity (BCVA) was 20/1,000 in the left eye. Ocular examinations showed frost-like opacities of the lens and a suspected break of the posterior capsule in the left eye. There were no detectable retinal lesions...

PURPOSE: To assess correlation between preoperative and postoperative findings and surgical factors, and postoperative functional outcomes after successful repair of acute macula-off rhegmatogenous retinal detachment (RRD). METHODS: Forty-four eyes of 44 patients with recent-onset macula-off RRD who had primary pars plana vitrectomy were included in this retrospective study. Best-corrected visual acuity (BCVA) and retinal and choroidal changes on spectral-domain optical coherence tomography (SD-OCT) were evaluated before and after surgery...

PURPOSE: To describe a new robot-assisted surgical system for retinal vascular bypass surgery (RVBS) and to compare the success rate with freehand RVBS. METHODS: A robot-assisted system for retinal microsurgery was constructed to include two independent robotic arms. A 23-gauge light probe and an intraocular forceps were affixed to the arm end effectors to perform the intraocular manipulation. Harvested porcine eyes were introduced to be established animal models of closed-sky eyeballs after that pars plana vitrectomy using temporary keratoprosthesis was performed by a skilful surgeon...

PURPOSE: To evaluate the incidence, characteristics, and the progression of epiretinal membrane (ERM) remnant edge seen by optical coherence tomography after ERM peeling. METHODS: A retrospective chart review was conducted for 86 eyes of 85 consecutive patients who were diagnosed with ERM and underwent pars plana vitrectomy for epiretinal membrane peeling between 2013 and 2014. Data collected and analyzed included age, gender, preoperative and postoperative visual acuity, use of indocyanine green dye to stain internal limiting membrane, tamponade used after vitrectomy, ERM edge boundaries, presence of cystoid macular edema, and central foveal thickness...

OBJECTIVE: To report and analyze the phenomenon of sticky silicone oil on the retina at the time of its removal. BACKGROUND: Silicone oil has been used for more than 25 years as a long-term retinal tamponade in the surgical management of patients with complex retinal detachments. When a decision to remove silicone oil was made at the end of the tamponade period, the system involved a number of different materials: silicone oil, aqueous solution with or without remnants of perfluorocarbon liquid plus the material of the cannula used to aspirate Silicone oil...

To report a case of upper eyelid swelling and ptosis caused by silicone oil migration in a patient after sutureless 23-gauge pars plana vitrectomy and silicone oil injection. A 36-year-old female was referred to eye clinic with total retinal detachment (RD) and superotemporal giant dialysis secondary to trauma in the left eye. Transconjunctival sutureless 23-gauge pars plana vitrectomy and intraocular silicone oil (1300 centistokes) injection were performed. After about 5 months, she came back with the left upper eyelid and periorbital swelling...

BACKGROUND: The vitreous is the clear jelly of the eye and contains fine strands of proteins. Throughout life the composition of this vitreous changes, which causes the protein strands in it to bundle together and scatter light before it reaches the retina. Individuals perceive the shadows cast by these protein bundles as 'floaters'. Some people are so bothered by floaters that treatment is required to control their symptoms. Two major interventions for floaters include Nd:YAG laser vitreolysis and vitrectomy...
