PURPOSE To psychophysically measure spherical and irregular aberrations in patients with various types of myopia correction. SETTING Laboratory of Experimental Ophthalmology, University of Groningen, Groningen, The Netherlands. METHODS Three groups of patients with low myopia correction (spectacles, soft contact lens, and Intacs) and 4 groups with high myopia correction (spectacles, rigid c...

BACKGROUND Visual outcome following repair of post-traumatic corneal perforation may not be optimal due to presence of irregular keratometric astigmatism. We performed a study to evaluate and compare rigid gas permeable contact lens and spectacles in visual rehabilitation following perforating corneal injuries. METHOD Eyes that had undergone repair for corneal perforating injuries with or wit...

Here we report a case of unexplained sudden visual loss after removal of silicone oil for rhegmatogenous retinal detachment repair. A patient with visual loss in one eye after removal of silicone oil was investigated with best-corrected Snellen visual acuity assessment, fundus biomicroscopy, optical coherence tomography, color fundus photograph, fluorescein angiography, electrophysiologic exami...

OBJECTIVES The objective of this study was to evaluate the relationship between the treatment of Helicobacter pylori gastric infection and changes in best-corrected visual acuity and macular detachment in patients with chronic central serous chorioretinopathy. METHODS Seventeen patients diagnosed with central serous chorioretinopathy were examined for gastric infection with Helicobacter pylor...

Previously reported superior visual acuity (VA) in autism spectrum conditions (ASC) may have resulted from methodological settings used (Ashwin, Ashwin, Rhydderch, Howells, & Baron-Cohen, 2009). The current study re-tested whether participants with (N=20) and without (N=20) ASC differ on psychophysical measures of VA. Participants' vision was corrected before acuity measurement, minimising refr...

purpose: to evaluate the efficacy and safety of ferrara intra-stromal corneal ring (fiscr) segments for keratoconus. methods: the study was performed on 57 eyes of 44 patients with keratoconus and clear cornea who were contact lens intolerant. subjects underwent complete ophthalmic examination before surgery. objective and subjective refraction achieving the best visual acuity was used to deter...

BACKGROUND To evaluate the effects on vitrectomy with internal limiting membrane (ILM) peeling versus vitrectomy with inverted internal limiting membrane flap technique for macular hole-induced retinal detachment (MHRD). METHODS Pubmed, Cochrane Library, and Embase were systematically searched for studies that compared ILM peeling with inverted ILM flap technique for macular hole-induced reti...

BACKGROUND The efficacy of a single dose of Ozurdex® was evaluated over a 6-month period in eyes with macular edema due to retinal vein occlusion and intraocular inflammatory disease. HISTORY AND SIGNS 20 eyes of 20 consecutive patients with macular edema received a single injection of Ozurdex® (intravitreal dexamethasone implant 0.7 mg). Patients with branch retinal vein occlusion (n = 11), ...

INTRODUCTION Myopia has become a big public health problem in certain parts of the world. Sight-threatening complications like choroidal neovascularisation membranes occur in up to 10% of pathological myopia, and natural history studies show a trend towards progressive visual loss. There are long-term financial and quality-of-life implications in this group of patients, and treatment strategies...

PURPOSE To explore a possible association between full-field electroretinograms with vitreomacular adhesion resolution and best-corrected visual acuity as part of the prospective, randomized, double-masked, sham-controlled Ocriplasmin for Treatment for Symptomatic Vitreomacular Adhesion Including Macular Hole (OASIS) trial studying ocriplasmin. METHODS The ERG substudy enrolled 62 of 220 OASI...
