purpose: to determine the anatomical location of the inferior oblique (io) muscle and any possible correlation between io overaction and io muscle mass. methods: in this interventional case series, eyes undergoing primary surgery for io overaction underwent measurement of the distance between io muscle borders from the limbus as well as muscle belly circumference, intraoperatively. results: ove...

We have used a scanning laser technique to measure in vitro changes in back vertex distance of chick and pigeon lenses. Enucleated eyes were dissected, leaving the lens naturally suspended by the ciliary body and intraocular muscles. Ray tracing techniques were used to measure the resting back vertex distance of the lenses by passing a laser beam through the lens and scanning it across the pupi...

AIM To compare the visual outcomes (distance and near) in patients opting for three different types of monofocal intraocular lens (IOL) (Matrix Aurium, AcrySof single piece, and AcrySof IQ lens). METHODS The present study is a cross-sectional analysis of secondary clinical data collected from 153 eyes (52 eyes in Matrix Aurium, 48 in AcrySof single piece, and 53 in AcrySof IQ group) undergoin...

PURPOSE To investigate the papillofoveal distance and its association with retinal thickness on optical coherence tomography (OCT) images after vitrectomy for diabetic macular edema (DME). METHODS In this retrospective case series, 72 eyes of 57 consecutive patients who underwent vitrectomy for DME were included. Retinal images dissecting the fovea horizontally were obtained using OCT before ...

PURPOSE To compare various biometric parameters between fellow eyes of acute primary angle closure (glaucoma) [APAC(G)] and fellow eyes of chronic primary angle closure (glaucoma) [CPAC(G)]. METHODS Ultrasound biomicroscopy examinations were performed on 47 patients with unilateral APAC(G) and 41 patients with asymmetric CPAC(G) before laser peripheral iridotomy and pilocarpine treatment. Ant...

The genus Dolomedes Latreille, 1804 present a very wide range of distribution on every continent except Antarctica (Platnick 2013) However, only one species has been reported from Madagascar, Dolomedes saccalavus Strand, 1907, which is unfortunately based on a juvenile specimen and was destroyed in wartime. We consider this a nomen dubium. In this work, one new species of Dolomedes Latreille, 1...

purpose : to evaluate the near visual performance of an accommodative intraocular lens (iol) tetraflex, in comparison to a standard monofocal foldable iol in cataract surgery. setting: eye research center , farabi eye hospital , department of ophthalmology, tehran university of medical sciences, iran . methods : forty six eyes of 23 patients with cataract underwent phacoemulsification and accom...

PURPOSE To investigate, through ultrasound biomicroscopy images, the presence of plateau iris configuration in eyes with narrow-angle from patients with open-angle glaucoma and in eyes with previous acute primary angle-closure and compare the biometric features of eyes with plateau iris configuration with those of normal eyes. METHODS Ultrasound biomicroscopic images from 196 patients with op...

PURPOSE To investigate the correlation between peripheral anterior synechia (PAS) and the quantitative anterior chamber angle parameters measured by ultrasound microscopy (UBM) in angle-closure glaucoma suspect (ACGS) eyes. METHODS Eyes were defined ACGS as having occludable angles and intraocular pressure less than 21 mm Hg without glaucomatous optic nerve head. The gonioscopic criteria for ...

PURPOSE To compare morphometric features between fellow acute primary angle-closure (APAC) eyes and glaucomatous or suspect eyes with narrow angle (NA). METHODS Fellow eyes of 30 patients with unilateral APAC and 30 with NA were evaluated by ultrasound biomicroscopy (UBM) under light and dark conditions. UBM parameters such as anterior chamber depth (ACD), angle opening distance at 250 microm...
