Background: The presence of an intraocular cilium is very rare and the response of the eye to the cilium is variable. We present the case of a patient with a cilium found in the vitreous cavity during vitrectomy for rhegmatogenous retinal detachment 40 years following penetrating eye injury. To our knowledge, this is the longest reported presence of a cilium in the vitreous cavity.

En células de la malla trabecular humana | 04 MAY 15 El glaucoma primario de ángulo abierto es una de las principales causas de pérdida de visión irreversible en todo el mundo. Se cree que el daño progresivo del nervio óptico y la pérdida de campo visual resultante son consecuencia de la presión intraocular (PIO) elevada. Dicho aumento de presión se debe al mal funcionamiento del drenaje de humor acuoso a través de la malla trabecular (MT). Entre 80 y 90% del flujo de humor acuoso se realiza a través de la malla trabecular, el resto por el cuerpo ciliar.
SPARC (sigla en inglés para proteína secretada, ácida y rica en cisteina) es una proteína matricelular, asociada con aumento de la fibrosis de los tejidos y procesos que perturban la homeostasis y que podría estar implicada en la patogénesis del glaucoma. Existen altos niveles de SPARC en la malla trabecular dentro de la región juxtacanicular. Ya se ha demostrado que la sobreexpresión de SPARC eleva la PIO, lo que impulso la identificación de moléculas farmacológicas que moderen dicha expresión.

Angle-closure glaucoma (ACG) occurring during those flights results in considerable morbidity and may cause permanent visual loss. It is preventable in patients with risk factors but may be an underrecognized and underreported phenomenon on long-haul flights. Observation We report a case series of 3 patients with ACG that developed on long-haul flights

Fernandes, M., Yang, X., Li, J. Y., & Cheikh‐Ismail, L. (2014). Smoking during pregnancy and vision difficulties in children: a systematic review. Acta ophthalmologica.
Abstract Cigarette smoking during pregnancy is a major public health concern. Intra-uterine exposure to maternal cigarette smoking is associated with increased risks of growth and neurodevelopmental problems during childhood and later life. Few studies have focussed on visual difficulties in children in the context of maternal smoking during pregnancy. A systematic search of online databases was carried out between February and May 2013 to examine the trend in visual outcomes in children exposed to maternal cigarette smoking during intra-uterine life. Twenty-four non-randomized studies were identified.

Abstract. Structured illumination microscopy provides twice the linear resolution of conventional fluorescence microscopy, but in thick samples, aberrations degrade the performance and limit the resolution. Here, we demonstrate structured illumination microscopy through 35 µm of tissue using adaptive optics (AO) to correct aberrations resulting in images with a resolution of 140 nm.

Purpose. We explored risk factors for myopia in 12- to 13-year-old children in Northern Ireland (NI). Methods. Stratified random sampling was performed to obtain representation of schools and children. Cycloplegia was achieved using cyclopentolate hydrochloride 1%. Distance autorefraction was measured using the Shin-Nippon SRW-5000 device. Height and weight were measured. Parents and children completed a questionnaire, including questions on parental history of myopia, sociodemographic factors, childhood levels of near vision, and physical activity to identify potential risk factors for myopia. Myopia was defined as spherical equivalent ≤−0.50 diopters (D) in either eye.

Background Dexamethasone intravitreal implant (DEX implant) is a sustained-release biodegradable implant approved for treatment of macular edema associated with retinal vein occlusion (RVO). The safety and efficacy of treatment of RVO-associated macular edema with sequential DEX implants in clinical practice was evaluated in patients who received DEX implant as monotherapy compared with patients who received DEX implant in combination with other RVO treatments.

This year marks the 90th anniversary for Ophthalmic & Physiological Optics (OPO) and its predecessor the British Journal of Physiological Optics. As part of the anniversary celebrations, we thought it pertinent to briefly discuss parts of the history of optometry (and linked branches of optics) research and its publication. We also ask the question of whether the breadth, quality and quantity of optometry journals are finally starting to catch up with the high quality of optometry research.

"Pueden ser la primera señal de una enfermedad que aún no se ha detectado y, cuando se producen de forma repetida, conducen al deterioro funcional" María De La Huerta A Coruña 29.04.2015 | 00:45 Galicia registra ya el doble de muertes por caídas fortuitas que en las carreteras, y se sitúa a la cabeza de España en fallecimientos por esa causa, que se incrementaron un 115% en una década, según los últimos datos del Instituto Nacional de Estadística (INE), correspondientes a 2013. El 85% de las víctimas de ese tipo de accidentes supera los 65 años, y la franja de edad en la que se contabilizan más decesos es la situada entre los 85 y los 89 años. "Las caídas en la tercera edad son mucho más frecuentes de lo que la gente cree y constituyen un importante problema de salud pública", asegura José Carlos Millán Calenti, catedrático de Gerontología de la Universidade da Coruña (UDC) y actual presidente de la Sociedade Galega...

Abstract Identification of retino-retinal projecting RGCs (ret-ret RGCs) has been accomplished by tracing RGCs in one retina after intravitreal injection of different tracers in the other eye. In mammals, rabbit and rat, ret-ret RGCs are scarce and more abundant in newborn than in adult animals. To our knowledge, ret-ret RGCs have not been studied in mice. Here we purpose to revisit the presence of ret-ret RGCs in juvenile and young adult rats and mice by using retrograde tracers applied to the contralateral optic nerve instead of intravitreally.

Agreement among optometrists and ophthalmologists in estimating limbal anterior chamber depth using the van Herick method. Ophthalmic and Physiological Optics, 35(2), 179-185. Abstract Purpose To evaluate the inter-observer agreement for measuring limbal anterior chamber depth (LACD) using the van Herick test in community optometrists, glaucoma specialist optometrists and ophthalmologists. Methods The study was divided into two phases. In the first phase, a random sample of 100 UK community optometrists were given an opportunity to select and grade eight digital slit-lamp images of anterior chamber angles using the original van Herick 4 point grading scale. The images were included in a clinical decision making study using computerised virtual case vignettes. In the second phase, hospital-based glaucoma specialist optometrists and glaucoma sub-specialist ophthalmologists graded the LACD of the right eye using a 7-point % grading scale in 57 consecutively presenting patients with suspect glaucoma. Inter-observer agreement was assessed using linearly weighted kappa (κw).

Objective To evaluate the clinical treatment effects of orthokeratology to slow the progression of myopia. Methods Several well-designed controlled studies have investigated the effects of orthokeratology in school-aged children. We conducted this meta-analysis to better evaluate the existing evidence. Relevant studies were identified in the Medline and Embase database without language limitations. The main outcomes included axial length and vitreous chamber depth reported as the mean ± standard deviation. The results were pooled and assessed with a fixed-effects model analysis. Subgroup analyses were performed according to geographical location and study design.
