PURPOSE To investigate the clinical course in patients who underwent surgical correction of consecutive esotropia. METHODS The medical records of 13 patients who underwent surgical correction of consecutive esotropia were reviewed retrospectively. The authors investigated the deviation and surgical method at the time of exotropia surgery. During the follow up period, the authors also studied ...

The assessment of anterior segment structures has become an important consideration for the planning of ocular refractive and cataract surgery, as well as for diagnosing and treating glaucoma and assessing corneal health. This assessment is typically performed by means of slit lamp biomicroscopy in clinical applications. An objective quantitative assessment of anterior segment structures is not...

PURPOSE To clarify whether myopes show poor accommodative response and thus have a larger accommodative lag under natural seeing conditions. METHODS Forty-three adults without other ocular abnormalities were classified into the early-onset myopia (EOM, n=28) and the emmetropia (EMM, n=15) groups. The subjects wore glasses or contact lenses that they habitually used, and accommodative response...

Keywords Amblyopia Anisometropia Corneal refractive surgery Amblyopia is one of the most important reversible eye disorders in children and different treatments are suggested. Early diagnosis and effective treatment in amblyogenic age are important criteria. These critical periods correspond to the period when the child's developing visual system is sensitive to abnormal input caused by stimulu...

Unilateral or bilateral lateral rectus resection is commonly performed for the correction of residual esotropia, but few results have been reported. Twenty-eight patients with residual esotropia underwent bilateral lateral rectus (BLR) resection. Six months after operation (n = 25), there were 17 (68%) successful cases, 7 (28%) cases of undercorrection, and 1 (4%) case of overcorrection. The su...

PURPOSE Human infants at greatest risk for esotropia are those who suffer cerebral insults that could decorrelate signals from the 2 eyes during an early critical period of binocular, visuomotor development. The author reared normal infant monkeys, under conditions of binocular decorrelation, to determine if this alone was sufficient to cause esotropia and associated behavioral as well as neuro...

PURPOSE Esotropia is a feature of albinism. Amongst esotropic patients there may be mild unrecognised albinos. Oculocutaneous albinism shares several clinical features with congenital esotropia. It is well known that mammals with oculocutaneous albinism have misrouted retinal ganglion cell axons, most likely caused by the absence of melanin or DOPA during development. We investigated the hypoth...

PURPOSE To compare objective and subjective accommodation and visual acuities with a new accommodative intraocular lens (IOL) (Lumina; AkkoLens Clinical BV, Rijswijk, The Netherlands) with a monofocal IOL and young phakic eyes. METHODS In this prospective, randomized controlled clinical investigation, patients aged 51 to 85 years with symptomatic cataract were enrolled in the study. A total o...

Investigations into the progression of myopia in children have long considered the role of accommodation as a cause and solution. Myopic children show high levels of accommodative adaptation, coupled with accommodative lag and high response AC/A (accommodative convergence per diopter of accommodation). This pattern differs from that predicted by current models of interaction between accommodati...

BACKGROUND To investigate the accommodative loads change needed to maintain binocular fusion in patients with intermittent exotropia (IXT). METHODS Seventeen consecutive patients with basic IXT and 15 normal controls were recruited. The WAM-5500 autorefractor (GrandSeiko, Fukuyama, Japan) was used to measure refractive error (D) under binocular and monocular viewing conditions at 6 m, 50 cm, ...
