ABSTRACT In this longitudinal study, we implanted 16 angle‐fixated anterior chamber intraocular lenses in phakic eyes of 13 patients to correct high myopia. Using fluorophotometry, we discovered a statistically significant decrease (P < .01) in lens transmittance. Blood‐aqueous barrier permeability tended to remain increased six months after surgery.

Confocal microscopy in ocular chrysiasis

Purpose To describe the presence of gold salt deposits in the corneal tissue of a patient treated with gold sodium thiomalate through confocal microscopy and to relate our findings to temporary corneal dynamics. Methods A patient who had been treated with gold sodium thiomalate for 6 years was referred from the Rheumatology Unit of our center for an ophthalmologic examination. At the time of examination she had been treatment-free for 9 years. Besides visual acuity, the examination included slit-lamp biomicroscopy, intraocular pressure, and fundoscopy. Confocal microscopy performed using a Confoscan P4 instrument with a 40× lens to obtain 15 images per second on an S-VHS video system (Panasonic) for subsequent analysis. Results The basic layered structure of the cornea was unaffected, but the presence of highly reflective particles was noted. These particles were interpreted as gold deposits in the corneal stroma, especially in the anterior and middle stroma. Conclusion Confocal microscopy is a useful method of evaluating the deposition of gold salts in tissues, particularly the cornea. Its future use will help gain a deeper understanding of corneal metabolism.

Triple clasificación de Madrid para el ojo seco

Desde el punto de vista del clinico, las enfermedades de Ojo Seco, incluidas en el sindrome de disfuncion de la pelicula lacrimal, tienen multiples causas etiologicas, distintas combinaciones de afectaciones anatomopatologicas y diversos grados de gravedad. El medico dacriologo debe conocer estos tres parametros, cuantificarlos, y establecer sobre ellos el tratamiento oportuno. Para ello, se ha elaborado la presente clasificacion clinica que en primer lugar incluye una clasificacion etiologica en causas etarias, hormonales, farmacologicas, inmunopaticas, hiponutricionales, disgeneticas, inflamatorias, traumaticas, neurodeprivativas y tantalicas, incluyendo cada uno de estos grupos numerosas variantes. En segundo lugar, una clasificacion histopatologica o ALMEN, acronimo de acuodeficiencia, lipodeficiencia, mucodeficiencia, epiteliopatia y afectacion de otras glandulas exocrinas no oculares. Y en tercer lugar, una clasificacion de gravedad en cinco escalones: subclinico (sintomas en situaciones de sobreexposicion), leve (sintomas habitualmente), moderada (sintomas y signos reversibles), grave (sintomas y signos irreversibles) e incapacitante (perdida irreversible de vision por dano corneal)

Objetivo/Metodo: Valorar la sensibilidad al contraste fotopica, sin y con deslumbramiento con un nuevo instrumento. Se estudiaron 78 ojos derechos de 49 adultos jovenes y de 29 adultos entre 35 y 55 anos. La sensibilidad al contraste se midio con el Contrast Glaretester CGT-1000 mediante una estrategia automatizada de reconocimiento para seis frecuencias espaciales. Resultados/Conclusiones: Los valores de sensibilidad al contraste fueron semejantes a los obtenidos con otros tests clinicos. El aumento de la edad disminuyo significativamente la sensibilidad al contraste sin y con deslumbramiento. Sin embargo, el deslumbramiento no modifico la sensibilidad al contraste fotopica.
