New mini-scleral lenses with bitangential peripheral geometry yield satisfactory clinical results and good subjective performance and are therefore an effective option for managing patients who have irregular astigmatism or other corneal pathology.
Based on these observations, we hypothesize that the congestion of the radial peripapillary capillary plexus might be a compensatory mechanism to the abnormal vasculogenesis occurring in the optic disc of patients affected by morning glory disc anomaly.
Central motion perception, as assessed by minimum displacement detection, was reduced by 25% in highly myopic eyes. Peripheral motion detection may be influenced by myopia, particularly in the inferior-nasal retina. Retinal stretching due to axial elongation may be linked to reduced performance in higher myopes.
Post-therapy Functional Magnetic Resonance Imaging in Adults with Symptomatic Convergence Insufficiency.
Observed activation pre-therapy consistent with top-down processing suggests that convergence requires conscious effort in symptomatic CI. Decreased activation in these areas after vergence-accommodative therapy was associated with improvements in clinical signs such as fusional vergence after vergence-accommodative therapy. The increase in blood o...
Within our study parameters, a thinner PoLTT under a small-diameter SL was associated with faster PoLTT mixing. However, there was no relationship between PoLTT and central corneal thickness during 5-hour SL wear.
The variability in the estimations of vision provides a promising novel means of detecting the intentional underrepresentation of vision and could help to minimize the chance of successfully cheating on tests of vision.
Direct stimulation of stereopsis at home using RDS in a game environment improves the stereoacuity in stereo-deficient subjects with a history of amblyopia.
Metaplasia of the LW epithelium was significantly greater in the early to moderate stages of CL. This supports the view that mechanical irritation is responsible for LW changes in CL wear. Ceasing CL wear seems to lead to recovery. Lid wiper staining did not reflect the underlying morphological changes.
The 2016 American Academy of Ophthalmology guidelines for hydroxychloroquine retinopathy were revised to reflect new dosing and care guidelines for early detection of retinal toxicity and to minimize the extent of irreversible vision loss.
Unlike NS participants, young adults in the VI group may not have search ability superior to children with VI, despite having the same level of visual functions (quantified by visual acuity and CS). This could be because of vision impairment limiting the developmental acquisition of the age dividend for peak performance. Older adults in the VI grou...
