The Agulhas Ridge, South Atlantic: the peculiar structure of a fracture zone [PDF]

, 2005
The Agulhas Ridge is a prominent topographic feature that parallels the Agulhas-Falkland Fracture Zone (AFFZ). Seismic reflection and wide angle/refraction data have led to the classification of this feature as a transverse ridge.

Medical and Surgical Treatment of Primary Angle Closure Glaucoma

Türk Oftalmoloji Dergisi, 2012
Primary angle closure glaucoma occurs when pathologies in the relative/absolute sizes or positions of anterior segment structures or abnormal forces in the posterior segment structures apply pressure on the peripheral iris, causing iridocorneal angle ...

Plateau iris secondary to iridociliary cysts

Archivos de la Sociedad Española de Oftalmología (English Edition), 2015
We present a case of plateau iris and glaucoma due to multiple unilateral iridociliary cysts. The patient was treated with iridotomy Nd: YAG laser and 360° iridoplasty, without achieving pressure control. Phacoemulsification improved the hypertension.
