visual impairment following stroke do stroke patients require Vision Assessment
Age and Ageing, 2008Co-Authors: Fiona J. Rowe, Darren Brand, A Price, Linda Walker, Shirley Harrison, Carla Eccleston, Claire Scott, Nitzan Akerman, Carole Jackson, Caroline DodridgeAbstract:Background: the types of visual impairment followings stroke are wide ranging and encompass low Vision, eye movement and visual field abnormalities, and visual perceptual difficuilties. Objective: the purpose of this paper is to present a 1-year data set and identify the types of visual impairment occurring following stroke and their prevalence. Methods: a multi-centre prospective observation study was undertaken in 14 acute trust hospitals. Stroke survivors with a suspectedvisualdifficultywererecruited.Standardisedscreening/referralandinvestigationformswereemployedtodocument data on visual impairment specifically Assessment of visual acuity, ocular pathology, eye alignment and movement, visual perception (including inattention) and visual field defects. Results: three hundred and twenty-three patients were recruited with a mean age of 69 years [standard deviation (SD) 15]. Sixty-eight per cent had eye alignment/movement impairment, 49% had visual field impairment, 26.5% had low Vision and 20.5% had perceptual difficulties. Conclusions: of patients referred with a suspected visual difficulty, only 8% had normal Vision status confirmed on examination. Ninety-two per cent had visual impairment of some form confirmed which is considerably higher than previous publications and probably relates to the prospective, standardised investigation offered by specialist orthoptists. However, under-ascertainment of visual problems cannot be ruled out.

profile and quality of life of children with dual sensory impairment or deafblindness in visually impaired special centres
Jurnal Sains Kesihatan Malaysia, 2019Co-Authors: Rokiah Oma, Wee Siew Peng, Wan Syafira Ishak, Nur Zakiah Mohd Saa, Victor Feizal KnighAbstract:Coping with dual sensory impairment or deafblindness can be a challenging task for an individual and for the caregiver. Currently limited information is available hence the objective of this study is to determine the profile and quality of life for children with dual sensory impairment or deafblindness. It is hoped that with this information, better rehabilitation programs can be designed for children with deafblindness in Malaysia. A purposive sampling was adopted. Children with dual sensory impairment were invited to participate in the study. Demographic and hearing loss information was extracted from the children’s medical records. Face to face interviews with parents were conducted using the SF-36 quality of life questionnaire. Vision Assessment comprising visual acuity, refraction, cover test, external ocular examination and children’s behaviour observations was conducted. Four children were identified based on sample size calculation and fulfilled the dual sensory impairment criteria out of the 44 children screened. The mean age was 9.3 ± 2.9 years old. Majority of the children were of Indian ethnicity. The category of deafblindness was congenital deafblindness with rubella as the main cause. All the children were premature babies but had a normal birth weight. The hearing profile showed the majority of them had bilateral profound hearing loss with mean pure tone average ranging between 50 dBHL and 120 dBHL. The main type of hearing problem was sensorineural and the majority of children owned hearing aids. The visual profile of the deafblindness children revealed either light perception (LP) and categorised as blind or low to moderate myopia. A majority had esotropia. All the children used braille as a visual aids and children with residual Vision used closed circuit teleVision (CCTV). Tactile methods were the main means for communication and majority of the children used a white cane. Behaviour and external observation Assessments concurred with the hearing and Vision impairment manifested. Quality of life in these subjects was lower in 7 out of 8 SF-36 dimensions as compared to normative values. Congenital deafblindness is the main category found among the children in this study and they had profound Vision and hearing losses. Tactile methods are the main means of communication for these children. Their quality of life was affected and introducing deafblindness rehabilitation, which includes a combination of hearing and low Vision rehabilitation, will be able to assist them in coping with their daily activities.

head mounted video magnification devices for low Vision rehabilitation a comparison with existing technology
British Journal of Ophthalmology, 1999Co-Authors: Robert Harper, Louise E Culham, Christine DickinsonAbstract:Patients with low Vision typically have reduced visual acuity and a significant loss of contrast sensitivity, often in combination with visual field loss. These impairments cause a number of disabilities including difficulty with reading, writing, recognising faces, watching teleVision, orientation and mobility, and completing activities of daily living. In a recent large scale survey of providers of low Vision services, Elliott et al 1found that for elderly patients with low Vision, the primary objectives identified at low Vision Assessment were to obtain help with reading and with Vision oriented performance of daily living activities. Secondary objectives commonly include obtaining help with watching teleVision, mobility and independent travel, and hobbies. In many cases, these objectives can be met by the prescription and use of conventional low Vision aids (LVAs)—that is, optical devices providing magnification in order to compensate for reduced visual acuity, while contrast is maximised with local task lighting. LVAs are, unfortunately, highly task specific, and the patient may need several different aids to deal with a variety of identified requirements. Recently, however, alternative devices have been introduced which offer a number of distinct advantages over conventional LVAs in low Vision rehabilitation. The purpose of this review is to describe these devices and to discuss both their current and future potential in comparison with existing technology. Contrary to early work suggesting that LVAs are often limited in their effectiveness,2 3 more recent studies indicate that low Vision rehabilitation and the prescription of LVAs can offer considerable benefit to the visually impaired, with at least one device being used by between 80% and 91% of patients provided with an LVA.4-8 It is recognised, however, that some patients do not continue to use LVAs following their dispensing. While some users discontinue with an LVA because of a change …

maternal and child health after assisted vaginal delivery five year follow up of a randomised controlled study comparing forceps and ventouse
British Journal of Obstetrics and Gynaecology, 1999Co-Authors: Richard Johanson, E Heycock, J E Carter, K Walklate, Abdul H Sultan, Peter J. H. JonesAbstract:Objective To undertake a five year follow up of a cohort of women and children delivered by forceps or vacuum extractor in a randomised controlled study. Design Follow up of a randomised controlled trial. Setting District general hospital in the West Midlands. Population Follow up questionnaires were sent to 306 of the 313 women originally recruited at the North Staffordshire Hospital to a randomised controlled study comparing forceps and vacuum extractor for assisted delivery. Two hundred and twenty-eight women responded (74.5%) and all were included in the study; forceps (n= 115) and vacuum extractor (n= 113). Main outcome measures Bowel and urinary dysfunction, child Vision Assessment, and child development. Results Maternal adverse symptoms at long term follow up were relatively common. Urinary incontinence of various severity was reported by 47%, bowel habit urgency was reported by 44% (98/225), and loss of bowel control ‘sometimes’ or ‘frequently’ by 20% of women (46/226). No significant differences between instruments were found in terms of either bowel or urinary dysfunction. Overall, 13% (20/158) of children were noted to have visual problems. There was no significant difference in visual function between the two groups: ventouse 11/86 (12.8%), compared with forceps 9/72 (12.5%); odds ratio 0.97,95% CI 0.38–2.50. Of the 20 children with visual problems, a family history was known in 18, and 17/18 (94%) had a positive family history for visual problems. No significant differences in child development were found between the two groups. Conclusions There is no evidence to suggest that at five years after delivery use of the ventouse or forceps has specific maternal or child benefits or side effects.
