Although internal seiches are ubiquitous in large, deep lakes, little is known about the effect of higher vertical-mode seiches on deepwater dynamics. Here, by combining entire summer season current and temperature observations and 3D numerical modeling, we demonstrate that previously undetected vertical mode-two and mode-three Poincaré waves in 309-meter deep Lake Geneva (Switzerland/France) generate bottom-boundary layer currents up to 4 cm s. Poincaré wave amphidromic patterns revealed three strong cells excited simultaneously.

Methods: Patients with genetically confirmed STL with axial length ≥ 26 mm and controls matched for axial length were included. The following data were obtained from SD-OCT scans and fundus photography: choroidal and retinal thickness (respectively, CT and RT), peripapillary atrophy area (PAA), presence of posterior staphyloma (PS).
Purpose: To compare the long-term outcomes of vitreomacular surgery in eyes with nontractional diabetic macular edema (DME) with those from eyes with tractional DME.
Methods: Retrospective comparative study from 55 consecutive patients (73 eyes). Twenty eyes were operated on for tractional DME and 53 eyes for nontractional DME unresponsive to laser photocoagulation or triamcinolone intravitreal injections.
Purpose: To evaluate the outcomes of epiretinal membrane (ERM) surgery in highly myopic eyes without traction maculopathy, and to compare them with those from non-highly myopic eyes.
Design: Retrospective nested case-control study from a cohort of 509 consecutive patients (509 eyes) who underwent pars plana vitrectomy with ERM removal.
Methods: Thirty-two highly myopic eyes (with a refractive error of more than -6.
Background: To evaluate the incidence, evolution, clinical characteristics, possible risk factors or preventive factors, and visual outcomes of epiretinal membrane (ERM) recurrence.
Methods: Retrospective study of 440 consecutive patients (440 eyes) who underwent pars plana vitrectomy for ERM. The internal limiting membrane (ILM) was peeled in 266 cases, with the help of indocyanine green in 27 cases and brilliant blue in 45 cases.
Purpose: To compare the 23-gauge (23-G) sutureless vitrectomy incision architecture in macular and non-macular surgery, using anterior segment spectral-domain optical coherence tomography (SD-OCT), and to evaluated its influence on clinical outcomes.
Methods: A prospective, observational case series of 43 patients who underwent primary transconjunctival 23-G pars plana vitrectomy (PPV) for macular and non-macular diseases. All sclerotomy wounds were imaged 1 day after surgery using the anterior segment module of SD-OCT (OCT Spectralis; Heidelberg Engineering, Heidelberg, Germany).
Purpose: To evaluate the factors affecting the postoperative intraocular pressure (IOP) decrease in 23-gauge (23-G) sutureless vitrectomy, including incision architecture evaluated by anterior segment spectral-domain optical coherence tomography (SD-OCT).
Methods: A prospective cohort study of 43 patients who underwent primary transconjunctival 23-G pars plana vitrectomy. All sclerotomy wounds were imaged 1 day after surgery using the anterior segment module of SD-OCT (OCT Spectralis, Heidelberg Engineering, Heidelberg, Germany).

Aim: To describe the incidence, clinical features, and evolution of paracentral retinal holes occurring after macular surgery.
Methods: A retrospective non-randomized study of 909 patients operated on for either a macular hole (MH, n = 400 patients) or an epiretinal membrane (ERM, n = 509 patients) between 2004 and 2009. Six patients (0.

Purpose: To compare the safety and functional outcomes of 25-gauge and 23-gauge (G) micro-incision vitrectomy surgery (MIVS) instrumentation with the standard 20-G vitrectomy system in the treatment of epiretinal membranes (ERM).
Methods: A retrospective comparative study of 553 consecutive cases with epiretinal membrane who underwent pars plana vitrectomy. Twenty-gauge, 25-gauge and 23-gauge vitrectomy was performed respectively in 347, 91, and 115 eyes.
Purpose: To report familial cases of birdshot chorioretinopathy (BSCR).
Design: Retrospective, observational case series.
Methods: Five families with 2 members in each (10 patients) with BSCR were included in this case series from a cohort of 225 patients followed up for BSCR.
Purpose: To analyze the features of retinal detachment (RD) occurring after cataract surgery performed by Kelman phacoemulsification (KPE) and to identify any potential correlations between KPE intraoperative complications and the features of RD (incidence apart) as well as the final visual outcome.
Design: Interventional consecutive case series.
Methods: Retrospective review of 114 eyes of 114 consecutive patients with RD occurring after KPE and followed for 6 months or more after surgery.
