Purpose To evaluate 24‐h intraocular pressure (IOP) rhythm reproducibility during repeated continuous 24‐h IOP monitoring with non‐contact tonometry (NCT) and a contact lens sensor (CLS) in healthy subjects. Methods Twelve young healthy subjects were housed in a sleep laboratory and underwent four 24‐h sessions of IOP measurements over a 6‐month period. After randomized attribution, the IOP of the first eye was continuously monitored using the CLS Sensimed TriggerFish® and the IOP of the fellow eye was measured hourly using the Pulsair Intellipuff® non‐contact tonometer. A nonlinear least‐squares dual harmonic regression analysis was used to model the 24‐h IOP rhythm. Comparison of acrophase, bathyphase, amplitude, the midline estimating statistic of rhythm (MESOR), IOP values, IOP changes and agreement were evaluated in the two tonometry methods. Results A significant nyctohemeral IOP rhythm was found in 31 out of 36 sessions (86%) using NCT and in all sessions (100%) using CLS. Hourly awakening during NCT IOP measurements did not significantly change the mean phases of the 24‐h IOP pattern evaluated using CLS in the contralateral eye. Throughout the sessions, intraclass correlation coefficients (ICCs) of the CLS acrophase (0.6 [0–0.9]; p=0.03), CLS bathyphase (0.7 [0.1–0.9]; p=0.01), NCT amplitude (0.7 [0.1–0.9]; p=0.01) and NCT MESOR (0.9 [0.9–1]; p<0.01) were significant. Conclusion The CLS is an accurate and reproducible method to characterize the nyctohemeral IOP rhythm in healthy subjects but does not allow to estimate the IOP value in millimeters of mercury corresponding to the relative variation of the electrical signal measured.

Both Casia and Visante AS-OCT demonstrate high repeatability. Except for the ACD and scleral spur angles, the two devices show good agreement.

Coagulase-negative staphylococci (CNS) cause the majority of post-cataract endophthalmitis, which can lead to anatomical and/or functional loss of the eye. This study reports the antibiotic susceptibilities of CNS isolates associated with acute post-cataract endophthalmitis cases and correlates antibiotic resistance with severity and outcome of infection in these patients. Clinical data (initial ocular examination, final prognosis, antibiotic treatment) and the antibiotic susceptibilities of the isolated CNS strains were obtained from 68 patients with post-surgical endophthalmitis recruited during a 7-year period by the FRench Institutional ENDophthalmitis Study (FRIENDS) group. The CNS strains displayed 100% susceptibility to vancomycin, 70% to fluoroquinolones, 83% to fosfomycin, 46% to imipenem and 18% to piperacillin. The most effective antibiotic combinations were fosfomycin plus a fluoroquinolone and imipenem plus a fluoroquinolone, which were considered adequate in 80% and 58% of patients, respectively. Methicillin resistance was significantly associated with older age (p 0.001), diabetes mellitus (p 0.004), absence of fundus visibility (p 0.06), and poor visual prognosis (p 0.03). Resistance to fluoroquinolones was significantly associated with absence of fundus visibility (p 0.05) and diabetes mellitus (p 0.02). This large prospective study demonstrates that methicillin resistance and, to a lesser extent, fluoroquinolone resistance in CNS strains causing postoperative endophthalmitis are both prevalent in France and associated with a poorer visual prognosis. These results emphasize the need for an effective surveillance of this antibiotic resistance and the development of new diagnostic tools for rapid detection for early optimization of antibiotic therapy in endophthalmitis patients.

Final prognosis was similar in eyes with RD secondary to open and closed globe injuries. The surgical technique depended mainly on lens status, type of retinal tear (dialysis and giant retinal tear), and the presence of preoperative proliferative vitreoretinopathy. Final prognosis (visual acuity ≥20/40) was associated with initial visual acuity >20/200 and macula-on status.

23-G TSV allows the surgeon to meet the same objectives as the 20-G technique for the treatment of endophthalmitis.
