We investigated the potential causal relationships between anisometropia, amblyopia and strabismus, specifically to determine whether either amblyopia or strabismus interfered with emmetropization. We analyzed data from non-human primates that were relevant to the co-existence of anisometropia, amblyopia and strabismus in children. We relied on interocular comparisons of spatial vision and refractive development in animals reared with 1) monocular form deprivation; 2) anisometropia optically imposed by either contact lenses or spectacle lenses; 3) organic amblyopia produced by laser ablation of the fovea; and 4) strabismus that was either optically imposed with prisms or produced by either surgical or pharmacological manipulation of the extraocular muscles...

Geriatric patients (age ≥ 65) are prone to complications after surgery and are at risk for severe thyroid eye disease (TED). In this study, we aim to identify preoperative demographic and TED patterns associated with geriatric patients who underwent decompression surgery, to examine the effect of age on postoperative strabismus rates, and to identify factors that may contribute to postoperative strabismus in the geriatric subgroup. We retrospectively reviewed patients who underwent thyroid-related orbital decompression surgery at the Kellogg Eye Center, University of Michigan, between 1999 and 2014...

Dong Cheol Lee, Se Youp Lee
BACKGROUND: Several inferior oblique (IO) weakening methods exist for correction of superior oblique palsy (SOP). A previously reported method involved recession and anteriorization according to IO overaction (IOOA) grade, which might be subjective and cause upgaze limitation and opposite vertical strabismus. Therefore, this study attempted to examine the efficacy of modified graded recession and anteriorization of the IO muscle in correction of unilateral SOP without resulting in upgaze limitation or opposite vertical strabismus...

BACKGROUND: The use of botulinum toxin as an investigative and treatment modality for strabismus is well reported in the medical literature. However, it is unclear how effective it is in comparison to other treatment options for strabismus. OBJECTIVES: The primary objective was to examine the efficacy of botulinum toxin therapy in the treatment of strabismus compared with alternative conservative or surgical treatment options. This review sought to ascertain those types of strabismus that particularly benefit from the use of botulinum toxin as a treatment option (such as small angle strabismus or strabismus with binocular potential, i...

BACKGROUND: Variable preoperative deviations and compensatory mechanisms may cause wrong dosage of strabismus surgery and result in over- or undercorrection. A long-lasting prism adaptation test (PAT) before surgery is supposed to reduce those difficulties and to improve the postoperative results. To date, the use of prism adaptation before surgery has not been systematically examined. METHODS: A total of 15 strabismologists and 28 orthoptists in Austria were interviewed about their approach to prism adaptation in 9 types of strabismus...
