THE use of the visuscope in an amblyopic eye helps to determine the part of the retina used during uniocular fixation. However, it is also important to know from a clinical standpoint whether the fovea is inhibited through a peripheral or a central mechanism, and whether in a particular case, the resolving power of the rods or the cones is affected. Various authors have studied the behaviour of...

MANY people are aware that the old idea in the treatment of squinting children was to prescribe glasses as required, and then, if the appearance of the eyes did not improve, wait until at least fifteen or sixteen years of age before operating. This postponement of operation until early adult life was considered essential, so that it could be performed without general ana-sthesia, and with the c...

CHAVASSE'S SQUINT. By T. Keith Lyle, C.BE., M.A., M.D., M.Chir. (Cantab.), M.R.C.P.(Lond.), F.R.CS.(Eng.), and G. J. 0. Bridgeman, M.C., M.A., M.B., B.Chir.(Cantab.), F.R.CGS.(Eng.). Ninth Edition. (Pp. viii+392; illustrated. 52s. 6d.) London: Bailliere, Tindall & Cox Ltd. THE presentation and scope of this book have both changed considerably since it was first written by Claud Worth in 1903. T...

Profound bradycardia during eye surgery is a potentially serious event. In clinical practice oculo-cardiac reflex (OCR) is most often encountered during squint surgery. The objective of this study was to assess the occurrence of OCR and prove the effect of ketamine as an induction drug and anticholinergic premedication (atropine) to prevent OCR. This study comprised 90 patients (aged 4-10 years...

BACKGROUND AND AIM Rectus muscle insertions are usually linear or slight curved with the anterior convexity. While operating squint surgeries, we found a presence of ridge-like structure at the medial rectus insertion. None of the other rectus muscle insertions had such structure. MATERIALS AND METHODS Patients undergoing squint surgery were included in the study. All the patients had negativ...

There has been increasing demand for accessible radio spectrum with the rapid development of mobile wireless devices and applications. For example, a GHz is needed fifth-generation (5G) cellular communication, but avail- able below 6 cannot meet such requirements. Fortunately, at higher frequencies, in particular, millimeter-wave bands, can be utilized through phased-array analog beamforming to...

To examine the link between binocular vision and binocular coordination of saccades we studied subjects with convergent strabismus since childhood with mild or no amblyopia: three subjects had small squint (< 10 prism D) and preserved peripheral binocular visual function with gross stereopsis; four subjects had larger squint (18-35 prism D) and no detectable stereopsis. A standard paradigm was ...

In the years 1977-8,258 infants weighing less than 1500 g were born at, or transferred to, the Royal Women's Hospital, Melbourne; 177 (68.5%) survived, and 111 of these attended for an ophthalmic examination. Significant ocular lesions were found in 37 (33%): 21 (19%) children had squint, 19 (17%) had a significant refractive error, 11 (10%) had cicatricial retrolental fibroplasia (RLF), and 3 ...

Gene products provided by the mother to the embryo determine the body axes in most animals. A recent study in zebrafish proposes that the TGFss signal Squint is one such factor.

Intelligent reflecting surfaces (IRSs) improve both the bandwidth and energy efficiency of wideband communication systems by using low-cost passive elements for impinging signals with adjustable phase shifts. To realize full potential IRS-aided systems, having accurate channel state information (CSI) is indispensable, but it challenging to acquire, since these devices cannot carry out transmit/...
