Abstract Choroidal neovascular membranes (CNVM) associated with pathological myopia (PM) can result in significant vision loss and legal blindness. These membranes usually occur subfoveally and are a major complication of PM, developing in approximately 5–10% of such eyes. PM is the second most common cause of choroidal neovascularization after age-related macular degeneration (AMD), and accounts for nearly 60% of CNVM cases in patients younger than age 50. Vascular endothelial growth factor-A has been implicated as the major angiogenic stimulus responsible for choroidal neovascularization secondary to AMD and several major studies have proved the benefits of anti-VEGF treatment for AMD-related CNVM.

Optics Letters. 2015; 40 (12):2842-2845 Abstract For high-resolution optical systems, a long depth of focus is desirable. Unfortunately, resolution and depth of focus are inversely related. In this work, a novel lens is presented to produce long depth of focus beams, keeping the same resolution.

Abstract
We report a high-energy picosecond optical parametric generator/amplifier (OPG/A) based on a MgO:PPLN crystal pumped by a fiber master-oscillator-power-amplifier (MOPA) employing direct amplification. An OPG tuning range of 1450-3615 nm is demonstrated with pulse energies as high as 2.6 μJ (signal) and 1.2 μJ (idler).

Glaucoma | 25 MAY 15 Investigación sobre la fisiopatología genómica y proteómica del glaucoma de pseudoexfoliación El glaucoma es una de las principales causas de ceguera irreversible en el mundo. Comprende una serie de patologías provenientes de la degeneración del nervio óptico y se diagnostica al observarse cambios estructurales en la cabeza del nervio óptico asociados con déficit del campo visual. El aumento de la PIO es el principal factor de riesgo de glaucoma y puede combatirse, a su vez el aumento de la PIO puede estar asociado con patología del nervio óptico por disminución de la perfusión del tejido o por daño mecánico a los axones en la cabeza del nervio óptico. Por lo tanto, el control y tratamiento de la PIO elevada es fundamental para pacientes con glaucoma. La causa principal de la PIO elevada es la resistencia al flujo saliente. El síndrome de pseudoexfoliación se caracteriza por la acumulación de material fibrilar en el ojo y otros tejidos del cuerpo. El material se encuentra en el segmento anterior, en forma de depósitos blancos como copos en la cápsula anterior del cristalino, en el margen del iris, la córnea y el ángulo irido-corneal.

Eisner, A. (2014). Sex, Eyes, and Vision: Male/Female Distinctions in Ophthalmic Disorders. Current eye research, (0), 1-6.
Abstract There is growing recognition: (1) that sex (male and female) and sex hormones (androgens and estrogens) are important for physiologic functions outside those pertaining expressly to reproduction, and (2) that both classes of sex hormones are active in both sexes, and moreover are produced locally in non-gonadal tissues throughout the body. The visual system, in addition to being of tremendous inherent importance, is unique in a very distinctive way; it possesses an organ – the eye – having a window allowing its interior to be examined with exquisite precision and control in both laboratory and clinical settings. Plus, many diseases manifest in the eye or are exclusive to the eye. This special issue of Current Eye Research contains 12 review articles, each addressing a different topical area important for Sex, Eyes, and Vision: Male/Female Distinctions in Ophthalmic Disorders.

POR GENÉTICA MÉDICA · 21 DE MAYO DE 2015 Almudena Avila-Fernandez , Raquel Perez-Carro , Marta Corton ,Carmen Ayuso .
La retinosis pigmentaria (RP, MIM 268000) es la distrofia de retina (DR) más común. Se presenta con una prevalencia de 1 en 4000 individuos, perteneciendo por ello al grupo de las enfermedades raras. La RP se caracteriza por la degeneración primaria de los fotorreceptores produciendo ceguera nocturna, pérdida del campo visual así como una disminución lenta y progresiva de la agudeza visual. La edad de inicio y la progresión de la enfermedad varían mucho de unos individuos a otros, incluso dentro de la misma familia. Además, la RP, al igual que el resto de las DR presenta una elevada heterogeneidad genética. Es una enfermedad monogénica que puede heredarse siguiendo todos los patrones de herencia mendeliana. Hasta la fecha se han descrito mutaciones asociadas a la RP en más de 70 genes. Aún así, éstas sólo explican el 50% de los casos. Esta heterogeneidad dificulta enormemente el manejo de los pacientes, especialmente la confirmación precisa de su diagnóstico y el consejo genético.

Abstract. We present a review of short-wave infrared (SWIR, defined here as ∼1000 to 2000 nm) spectroscopy and imaging techniques for biological tissue optical property characterization. Studies indicate notable SWIR absorption features of tissue constituents including water (near 1150, 1450, and 1900 nm), lipids (near 1040, 1200, 1400, and 1700 nm), and collagen (near 1200 and 1500 nm) that are much more prominent than corresponding features observed in the visible and near-infrared (VIS-NIR, defined here as ∼400 to 1000 nm).

Survey of ophthalmology, 60(3), 196-203. Abstract Pain in ophthalmic surgery is a neglected area. We systematically reviewed the factors associated with postoperative pain and analgesic consumption in ophthalmic surgery and found 12 studies with 1,515 participants. The median number of patients in the included studies was 59. Female sex, longer duration of surgical procedure, second eye surgery as a consecutive procedure, type of surgery, general anesthesia, lower satisfaction with anesthesia, and postoperative nausea may contribute to increased postoperative pain intensity

Bruno, A., Ayhan, I., & Johnston, A. (2015). Changes in apparent duration follow shifts in perceptual timing. Journal of Vision, 15(6).
Itis well established that the apparent duration of moving visual objects is greater at higher as compared to slower speeds. Here we report the effects of acceleration and deceleration on the perceived duration of a drifting grating with average speed kept constant (10°/s).For acceleration, increasing the speed range progressively reduced perceived duration. The magnitude of apparent duration compression was determined by speed rather than temporal frequency and was proportional to speed range (independent of standard duration) rather than acceleration. The perceived duration reduction was also proportional to the standard length. The effects of increases and decreases in speed were highly asymmetric.

Abstract Presbyopia occurs in the aging eye due to changes in the ciliary muscle, zonular fibers, crystalline lens, and an increased lens sclerosis. As a consequence, the capacity of accommodation decreases, which hampers to focus near objects. With the aim of restoring near vision, different devices that produce multiple focuses have been developed and introduced. However, these devices are still unable to restore accommodation.

Abstract Straylight, lens yellowing and ocular aberrations were assessed in a group of people with type 1 diabetes and in an age matched control group. Most of the former had low levels of neuropathy. Relative to the control group, the type 1 diabetes group demonstrated greater straylight, greater lens yellowing, and differences in some higher-order aberration co-efficients without significant increase in root-mean-square higher-order aberrations. Differences between groups did not increase significantly with age.
