215 preschool siblings of children presenting with squint/amblyopia were screened by refraction after cycloplegia. The presence of +2.00 or more D of spherical hypermetropia in both eyes, or +1.00 or more D sphere or cylinder of anisometropia was significantly associated (P=0.0779%) with that child being identified 2+ years later as having either squint or amblyopia or both. Astigmatism of +1.5...

An improved range-Doppler algorithm (RDA) is proposed to reconstruct images from synthetic aperture radar (SAR) data received at high squint angles. At a higher squint angle, a larger synthetic aperture is required to receive sufficient amount of data for image reconstruction, and the range migration also becomes more serious, which demands more computational load and larger memory size. The pr...

AIM To investigate the effect that squint surgery has on pupillary diameter. METHODS The effect of squint surgery on pupil size was investigated in 19 patients. RESULTS A significant mydriasis in the operated eye was observed when compared with the unoperated eye. This was independent of the number or type of extraocular muscles operated upon. CONCLUSION It is hypothesised that this chang...

Purpose To report a case of filamentary keratitis occurring in the cornea hidden under the eyelids by squint surgery. Methods A 69-year-old female patient with a history of amblyopia was referred for intractable filamentary keratitis in the left eye. The strabismus angle was 35Δ hypertrophic, and ocular motility was within the normal range. Slit-lamp examination of her left eye revealed filam...

Ten patients in the age range 2 to 22 years are described who had operations initially for squint in childhood. Nine had had concomitant convergent strabismus and one divergent. All presented again in adult life with a cosmetic complaint, but two also had diplopia. Reoperations were done, age range 14 to 43. These ten were all the "late reoperations" for squint which were done during the four y...

PURPOSE To compare the results between recession of the lateral recti and monocular recess-resect procedure for the correction of the basic type of intermittent exotropia. METHODS 115 patients with intermittent exotropia were submitted to surgery. The patients were divided into 4 groups, according to the magnitude of preoperative deviation and the surgical procedure was subsequently performed...

Recently, we developed a model of binocular fixation. This model predicts the amount of cyclovergence as a function of target elevation and horizontal target vergence. The prediction derives from the assumption that version and vergence add linearly and that the eye positions are constrained in three respects: (1) the foveae of the two eyes are directed towards the target, (2) the version compo...

PURPOSE To analyze the postoperative strabismic angle for five years or more and to investigate when the angle stabilized in intermittent exotropia. METHODS We retrospectively reviewed the clinical records of 89 patients who had undergone surgery for intermittent exotropia. The postoperative strabismic angles measured were analyzed at one-year intervals up to five years postoperatively. We di...
