Background Contemporary data for causes of vision impairment and blindness form an important basis of recommendations in public health policies. Refreshment of the Global Vision Database with recently published data sources permitted modelling of cause of vision loss data from 1990 to 2015, further disaggregation by cause, and forecasts to 2020.

Chapter
Consideration of patient characteristics is vital for indication of anesthesia in manual small-incision cataract surgery. Local techniques, including topical, intracameral, and regional blocks (retrobulbar, peribulbar, and sub-Tenon’s block), are commonly used with advantages, disadvantages, and associated complications, which will be described. To...

Data on causes of vision impairment and blindness are important for development of public health policies, but comprehensive analysis of change in prevalence over time is lacking.
Article
Purpose: To examine the agreement and relationship between refractive and corneal astigmatism in a population of pseudophakic eyes. Methods: Patients of age at least 40 years, visual acuity 20/40 or better, and no ocular disease were included (n = 111). Refractive astigmatism was obtained by subjective refraction. Corneal astigmatism was measure...

Purpose. To report management of diplopia with botulinum toxin injection in traumatic multiple ocular motor cranial neuropathies. Methods. Alternate prism and cover measurement of deviation in different positions of gaze, examination of ductions, field of binocular single vision, and complete ocular anterior and posterior segment evaluation were c...
Chapter
In this chapter, we summarize advances in the understanding of factors that control refractive development and refractive state of the eye, particularly by retinal mechanisms. When the normal refractive development process towards emmetropia (emmetropization) fails, it leads to refractive errors, such as myopia or hyperopia, which are highly preval...
Article
These are commentaries on a Cochrane review, published in this issue of EBCH, first published as: Li T, Shotton K. Conventional occlusion versus pharmacologic penalization for amblyopia. Cochrane Database of Systematic Reviews 2009, Issue 4. Art. No.: CD006460. DOI: 10.1002/14 651 858.CD006460.pub2. Further information for this Cochrane review is a...
Article
To compare a surgically adjusted dose of strabismus surgery using topical anesthesia in cooperative patients with dosage guidelines adapted to the surgeon's personal technique using sub-Tenon's anesthesia. Randomized, controlled, single-site clinical trial. Sixty patients with nonparalytic, nonrestrictive esotropia who were cooperative for surgery...
Article
To investigate the outcomes and predictive factors of surgical treatment of oculomotor nerve palsy. Records of patients requiring eye muscle surgery for oculomotor nerve palsy in our institution were retrospectively reviewed. Age, sex, etiology, deviation, completeness of involvement, time between onset and surgery, botulinum toxin treatment, and n...
Article
To study the appropriate timing of corneal suture removal in sequential surgery (penetrating keratoplasty [PK]-phacoemulsification [PE]) procedures. In a pilot study, patients with a PK double running suture in place requiring cataract surgery were randomized to suture removal 1 month before PE or during PE (n = 14; 7 in each group). Visual acuity,...

Article
Traditional treatment of amblyopia, although still in use and of great value, has recently been challenged by data from studies relative to efficacy of different modalities and regimens of therapy. LogMAR-based acuity charts should be used, whenever possible, for diagnosis and monitoring. Refractive errors of certain magnitude should be prescribed,...
