Introduction: Posterior segment retained Intraocular foreign body (IOFB) management is challenging. Facility of pars plana vitrectomy (PPV) and availability well trained vitreo retina surgeons are the basic need to accomplish this work. Encircling band provide permanent 360° support close anterior retinal break prevent traction on retina. The objective study analyse clinical characteristics pre...

background: adverse effect of sun rays mainly uv ray on the human eye documented and protection of eyes is necessary using different methods such as, sun glasses. sunglasses are designed in different colors. the aim of this study was evaluation of the effect of different colors of sunglasses on the visual acuity, contrast sensitivity, stereopsis and color vision. methods: 81 normal subjects wer...

The Joint Commission recently reversed its prior authorization of the use of secure clinical texting to issue patient care orders, now again prohibiting texting of orders. However, the potential sole or exclusive use of clinical texts to transmit other patient care information beyond care orders still poses a risk to patient safety in high acuity care because of text transmission delays resulti...

purpose : to assess the results of intracorneal ring (icr) segments for treatment of patients with pellucid marginal degeneration (pmd) methods : in this prospective interventional case series study, eight eyes of 5 patients with pmd who were contact lens intolerant received one or two intacs (intacs, addition technology) segments. preoperative and postoperative evaluations included slit-lamp e...

background: taking visual acuity is an important part of an eye routine examination. this study was conducted to compare visual acuity measured using an iranian digital tumbling e chart with visual acuity measured using an italian digital tumbling e chart as a familiar foreign chart. materials and methods: this study was carried out on 200 participants (400 eyes; healthy n=40, glaucoma n=40, re...

PURPOSE We intended to assess consequences of reduced visual acuity for performance in a natural simple motor task (tracing) using objective kinematic performance measures. Specifically, we intended to elucidate the kind of relationship between the task performance and best corrected binocular visual acuity and to determine the threshold of visual acuity when task performance starts to deterior...

PURPOSE The present investigation compared recognition acuities (ETDRS chart) with resolution acuities (Landolt-C chart) in a sample of patients with idiopathic macular holes (MH). Traditionally, visual acuity in a clinical setting is measured with a letter chart. Yet, the ability to recognize a letter differs from a resolution task, such as detecting the direction of a gap in a ring. It was hy...
