Life happens on small and grand scales, right in front of us and from afar; most of us want to experience all of it. Since the first bifocal IOLs were developed in the 1980s, scientists and manufacturers have been on a dedicated mission to provide individuals with great vision at all distances after cataract surgery. Following those early bifocal lenses, the development of multifocal lenses pro...

AIM Treatment options for idiopathic intracranial hypertension (IIH) are lumbar peritoneal shunt (LP), optic nerve fenestration, ventriculoperitoneal shunt and venous stenting. We report our experience of 24 cases of LP shunt. MATERIAL and METHODS All the patients had preoperative fundus examination, cerebrospinal fluid pressure estimation and examination, visual field charting, C...

OBJECTIVE To describe the possible impairment of binocular vision in primary open angle glaucoma (POAG) patients. METHOD A cross-sectional study was conducted on 58 glaucoma patients, 76 ocular hypertensives and 82 normal subjects. They were examined with a battery of binocular tests consisting of the measurement of phoria angles, amplitudes of fusion (AF), near point of convergence (NPC) ass...

A certain percentage of patients complain of "glare" at night after undergoing a refractive surgical procedure. When patients speak of glare they are, technically, describing a decrease in quality of vision secondary to glare disability, decreased contrast sensitivity, and image degradations, or more succinctly, "night vision disturbances." The definitions, differences, and methods of measureme...

Animal multisensory systems are able to cope with discrepancies in information provided by individual senses by integrating information using a weighted average of the sensory inputs. Such sensory weighting often leads to a dominance of a certain sense during particular tasks and conditions, also called sensory capture. Here we investigated the interaction of vision and active electrolocation d...

All RDs are accompanied by some loss of visual function but this will vary depending upon the type of detachment, its size, and retinal location, making it difficult to ascribe one set of symptoms to the condition (Box 71.3). Diagnosing RD is complex with many qualifications. Abnormal vision is the only reliable symptom of RD. But the types of abnormal vision are large and varied: light flashes...

7 Abstract — Occupational diseases and harmful effects on the human body industry were concerns in many scientific papers over time. Since the vision is one of our senses responsible for the comfort and quality of life, is very important to know what are the factors that can lead to decreased quality of vision, to try to prevent and, where appropriate, to investigate and find solutions for ocul...

PURPOSE To report a case of recurrent nummular keratitis in a pediatric patient with Hyperimmunoglobulinemia D syndrome. METHODS A retrospective chart review. RESULTS A 14-year-old boy with Hyperimmunoglobulinemia D syndrome (HIDS) presented with photophobia and ocular irritation concomitant with disease exacerbation. He was found on exam to have significant nummular keratitis, which respon...

The epiretinal membrane (ERM) is semitransparent; fibrocellular membrane found on the inner surface of the internal limiting membrane (ILM) at the macula [1]. ERM most commonly take place in the elderly population and can lead to distortion, blurring of vision, and in some patients severe vision loss [13]. ERM formation may lead to visual inconveniences, such as metamorphopsia, photopsia, blurr...
