One of the serious vision threatened complications cataract surgery is refractory PCME. That why this complication has to be managed in time and adequately. Non steroidal antiinflammatory anti VEGF agents like bevazicumab are useful for OCT an important role detecting PCME measurement central macular thickness control treatment In case study patient after rutin uncomplicated FACO with at postop...

Our goal is to link spatial and temporal properties of letter recognition to reading speed for text viewed centrally or in peripheral vision. We propose that the size of the visual span - the number of letters recognizable in a glance - imposes a fundamental limit on reading speed, and that shrinkage of the visual span in peripheral vision accounts for slower peripheral reading. In Experiment 1...

Orbital cellulites is an uncommon infectious process in which patient may present with pain, reduced visual acuity, compromised ocular motility and significant proptosis. [1][3] In the modern era of relatively early access to the health care facilities, complete loss of vi‐ sion from orbital cellulitis is rare. In the vast majority of cases, a history of upper respirato‐ ry tract infection prio...

A forty-two year old lady presented with gradual, painless, progressive blurring of vision of her left eye for four months. There were no other associated ocular or systemic complaints. Examination showed decreased visual acuity in both eyes and a pale optic disc on the left side. Visual field examination revealed a temporal field defect of the right eye which aroused the suspicion of an intrac...

The effect of peribulbar anaesthesia on optic nerve function in 20 patients, before and after cataract surgery, was measured. All the patients had decreased visual acuity. Five (25%) had no perception of light. Seventeen (85%) developed a relative afferent pupil defect (RAPD). No patients saw the operating instruments. Seven (35%) had improved visual acuity immediately postoperatively. Patients...

This paper presents an optimized algorithm for robot localization which increases the correctness and accuracy of the estimating position of mobile robot to more than 150% of the past methods [1] in the uncertain and noisy environment. In this method the odometry and vision sensors are combined by an adapted wellknown discrete kalman filter [2]. This technique also decreased the computation pro...

During 2005 through 2008, NASA defined and implemented a major evolutionary change in it Earth Observing system Data and Information System (EOSDIS) to modernize its capabilities. This implementation was based on a vision for 2015 developed during 2005. The “EOSDIS 2015 Vision” emphasizes increased end-to-end data system efficiency and operability; increased data usability; improved support for...

Decreased discrimination of colors caused by adverse environment, such as long-term occupational exposure to or consumption of drugs, substances, and food containing neurotoxic chemicals. Color vision early manifests adverse effects of exposure to an environment that contains neurotoxic substances [1, 2]. The acquired color vision impairments, or dyschromatopsias, can be very subtle (subclinica...

BACKGROUND We are reporting a case of granulomatous panuveitis in the right eye following penetrating injury to the left eye. FINDINGS A 34-year-old female was diagnosed to have sympathetic ophthalmia on treatment with systemic steroids. Vision did not improve in spite of aggressive systemic steroid therapy. On examination, patient had large retinal pigment epithelial rip nasal to the disc wi...
