Leber hereditary optic neuropathy (LHON) is a mitochondrial disease leading to rapid and severe bilateral vision loss. Idebenone has been shown to be effective in stabilizing and restoring vision in patients treated within 1 year of onset of vision loss. The open-label, international, multicenter, natural history-controlled LEROS study (ClinicalTrials.

Purpose: Myotonic dystrophy type 1 is the most common muscular dystrophy in adulthood, caused by a triplet repeat in chromosome 19q13.3. The present study investigates the frequency of the different ocular alterations in Spanish patients with DM1 and its relationship with the severity of the genetic alteration.

Purpose: To evaluate the effectiveness of in---travitreal bevacizumab injections following a single dexamethasone implant in the treatment of macular edema secondary to branch and central retinal vein occlusion.
Methods: This was a prospective interventional non-comparative study, 44 eyes of patients with naïve macular edema related to branch and central retinal vein occlusion were treated with a dexamethasone implant. Patients were followed-up at four-week intervals from the second to the sixth month.
Purpose: Patient satisfaction is important in the treatment of glaucoma. Suboptimal compliance and impaired long-term outcome are a likely result of poor tolerability. The present multicentre, international, transverse, epidemiological survey was conducted to assess the satisfaction of patients who had received preservative-free latanoprost (PFL) for at least 3 months.

Methods: We reviewed a total of 307 VFs performed with a face mask (FPP2/KN95 or surgical masks) and compared them with prior VFs, performed before the pandemic. VFs with suspected pseudoprogression due to mask artefacts (VF test 1) were repeated with a surgical mask and an adhesive tape on its superior border (VF test 2) to distinguish from true VF loss.
Objectives: To describe the characteristics and hygiene habits of contact lens (CL) wearers who acquire CLs over the Internet, as well as their awareness of modifiable risk factors (RFs).
Methods: A web-based survey was conducted among clients of an online CL sales platform during 6 months. Demographic data, CL hygiene-related awareness, and compliance were collected and analyzed.
Objective: To describe the safety and effectiveness of CyPass supraciliary microstent implantation alone in eyes with open-angle glaucoma (OAG) followed up for up to 3 years.
Methods And Analysis: This registry study included subjects with primary or secondary OAG who underwent CyPass Micro-Stent implantation alone at 12 sites in four European countries to reduce intraocular pressure (IOP) and/or use of IOP-lowering medications. The primary safety outcome was the incidence of adverse events.
Purpose Of Review: Mild papilledema may be difficult to distinguish by clinical observation from pseudopapilledema. An accurate diagnosis is critical to avoid invasive workup and unwarranted treatment. In this review, we focus on the development and subsequent role of optical coherence tomography (OCT) in detecting and differentiating optic nerve head drusen (ONHD) from papilledema and other causes of acquired swelling of the optic disc.

Because glaucoma is a chronic condition in which the therapeutic response is dependent on adherence to treatment, patient acceptability is an important factor in achieving satisfactory outcomes. This multicenter, international (Belgium, the Netherlands, and Spain), epidemiological convenience sample survey among patients commencing treatment with preservative-free latanoprost collected data on patient satisfaction with particular regard to tolerability.

Methods: This study combines a phase I and two phase II clinical trials to test different doses of SYL1001 in a total of 156 healthy subjects and patients with DED. After 10 days of treatment, the primary efficacy endpoints were the effect on (1) the scoring in the Visual Analogue Scale (VAS) and Ocular Surface Disease Index (OSDI) questionnaires, and (2) ocular tolerance evaluated by corneal fluorescein staining and conjunctival hyperemia.
Purpose: We investigated the early effects of intravitreal aflibercept injection (IAI) on optic nerve head (ONH) morphology.
Methods: All of the participants underwent applanation tonometry and enhanced depth imaging by spectral-domain optical coherence tomography immediately before injection, and within 5 and 30 minutes after IAI. Changes in the anterior lamina cribrosa surface depth, prelaminar tissue thickness (PTT), optic cup width, optic cup depth, and Bruch's membrane opening (BMO) were assessed.
Purpose: To evaluate and compare the wave amplitude of multifocal electroretinogram (mfERG) measurements and discomfort from Dawson-Trick-Litzkow (DTL) electrode located on the cornea (cDTL) and on the conjunctival fornix (fDTL) and ERG-jet contact lens electrode (CL).
Methods: Thirty-six patients and 18 healthy volunteers were evaluated with three different methods (cDTL, fDTL and CL). Wave amplitude, number of artifacts, number of electrode dislocations and level of discomfort obtained with each electrode were compared.
Cyclodialysis is the result of the separation of the longitudinal ciliary muscle fibers from the scleral spur, which creates an abnormal pathway for aqueous humor drainage that may lead to ocular hypotony. For many years cyclodialysis was considered a treatment option for glaucoma. However, today it usually occurs as a complication of blunt trauma or more rarely as a complication of anterior segment ocular surgery.

Methods: Ten eyes from ten patients diagnosed with NAION and treated during the acute phase with 80 mg daily, tapering-down dose of corticosteroids were compared with a non-contemporary cohort of 27 patients that received no treatment. The visual outcomes of treated and untreated group were compared.
Background: The causes of persistent submacular detachment after successful rhegmatogenous retinal detachment (RRD) surgery remain unknown. Its presence is associated with poor postoperative visual acuity, but due to its spontaneous resolution no additional therapeutic or diagnostic procedure is recommended.
Case Report: A case of central serous chorioretinopathy (CSC) that simulated persistent subfoveal fluid after RRD surgery is presented.
Introduction: Patients with glaucoma or ocular hypertension who do not achieve target intraocular pressure (IOP) using one hypotensive agent are often transitioned to combination therapy. Travoprost 0.004%/timolol 0.

Methods: Retrobulbar blood vessels of 26 eyes (14 patients) that underwent orbital bone decompression between June 2009 and May 2010 were measured prospectively using color Doppler ultrasound before and after surgery. The disease was inactive in all patients enrolled according to the European Group on Graves' Orbitopathy.
Purpose: To identify the clinical and anatomic characteristics of filtering blebs after nonpenetrating deep sclerectomy (NPDS) using ultrasound biomicroscopy, and to evaluate its influence on intraocular pressure (IOP) control.
Methods: We conducted a prospective interventional case series in 18 eyes of 18 patients who had undergone nonpenetrating deep sclerectomy with Esnoper® implant. A complete ophthalmic examination and ultrasound biomicroscopy (UBM) exploration were performed at 1, 3, and 6 months postoperatively.
Purpose: To evaluate and compare toric intraocular lens (IOL) implantation and spherical IOL implantation with peripheral corneal relaxing incisions to manage astigmatism during phacoemulsification.
Setting: Ophthalmology Service, Hospital Ramón y Cajal, Madrid, Spain.
Design: Prospective randomized comparative case series.
