PURPOSE To evaluate factors associated with the direction of horizontal deviation in the sensory strabismus of patients with unilateral organic amblyopia. METHODS The medical charts of 53 patients who had been diagnosed with sensory strabismus between 2000 and 2009 were reviewed retrospectively. The underlying ocular disease, time of onset and the duration of vision impairment, refractive err...

A knowledge of the optic disc size may be of value when assessing the glaucoma suspect. The vertical diameter of the optic disc was measured using a Zeiss four mirror gonioscope and a 900 Haag-Streit slit-lamp in one eye of 39 patients, 32 with refractive errors within 3 dioptres of emmetropia. The disc was measured by projecting a slit beam of known height onto the image of the disc. A magnifi...

PURPOSE Peripheral hyperopia was hypothesized to stimulate axial elongation. This study describes peripheral refraction and its associations with central refractive error in young Singapore Chinese children. METHODS Two hundred fifty children aged 40 months or older recruited from the Strabismus, Amblyopia, and Refractive Error in Young Singapore Children study were included in this analysis....

PURPOSE To evaluate effectiveness, safety, predictability, and short-term stability of laser in situ keratomileusis (LASIK) using the LaserSight Compac-200 Mini excimer laser with software version 9.0, for all refractive errors. METHODS One hundred fifty consecutive patients (300 eyes) that received bilateral LASIK for myopia, hyperopia, and astigmatism were studied prospectively. A new 9.0 s...

Until recently, the pursuit of emmetropia in patients with astigmatism (around 30% of the population) was infeasible since the only intraocular lenses available on the market were designed to correct myopia or hyperopia. However, with the new toric lens designs now available, a patient’s cataract, myopia, hyperopia and astigmatism can all be corrected by means of a simple, safe operation follow...

Corneal topography of a harbor seal measured with a Placido's disc shows a central flattened stripe in the vertical meridian. Together with a pupil that can form a vertical slit, the flat vertical meridian can minimize the optical effects caused by the transition from water to air. Using infrared (IR) photoretinoscopy, we analyzed the refractive state of harbor seals and revealed a high degree ...

Lens damage during phakic intraocular lens implantation is a major complication. A case of a patient who developed lens vacuoles during toric implantable collamer lens (ICL) removal from her right eye and insertion of a new non-toric ICL due to persistent rotation of the former is presented in this work. As this event is very uncommon when implanting phakic intraocular lenses, the performed sur...
