“…Three of the six case–control studies at moderate risk of bias found evidence of lower visual acuity in the groups with psychotic illness for at least some types of vision, 21 , 65 , 72 while the remaining three found no difference between the groups. 62 , 63 , 66 One study found that the lower visual acuity applied to people with established schizophrenia, but not people with first‐episode psychosis.…”

Objectives Several theories propose that visual acuity impairment is associated with psychosis. Visual impairment could lead to psychosis or the converse, or they may share underlying pathology or risk factors. In the first evidence synthesis in this area for over 25 years, we collated studies measuring the association between visual acuity impairment and psychosis. Methods We searched the MEDLINE, EMBASE, PsycINFO, and Web of Science databases for studies published from 1992 to 2020, using the Newcastle Ottawa Scale to assess risk of bias. We narratively synthesized findings and meta‐analyzed sufficiently homogenous results. Results We included 40 papers, which reported on 31 studies. Evidence from seven cohort studies was inconsistent, which precluded meta‐analysis of this study design. These contradictory results also made it difficult to draw conclusions regarding a temporal association. We found evidence for an association from eight cross‐sectional studies treating visual acuity impairment as the exposure and psychosis as the outcome [pooled odds ratio (OR) =1.76, 95% confidence interval (CI): 1.34–2.31], and four with the reverse exposure and outcome (OR: 1.85, 95% CI: 1.17–2.92). Seven case–control studies with mixed findings were found, but only two primarily addressed our research question, and these findings were mixed. Conclusions Although evidence supports a cross‐sectional association between visual acuity impairment and psychosis, further research is needed to clarify the temporal direction, given the mixed findings in cohort studies. Understanding the association may give insights into prevention strategies for people at risk of visual acuity impairment and psychosis.

“…The Freiburg test is a computerized visual acuity test. 71 Five studies allowed some degree of correction of impairment using aids during the measurement, 21 , 55 , 63 , 64 , 66 , 72 , 73 and two did not state whether correction was employed. 65 , 69 The number of participants in each study ranged from 60 to 130.…”

“…Furthermore, deficits in LSF processing are related to impairments in object recognition [ 110 ], face processing, and facial emotion recognition in schizophrenia [ 4 , 78 , 111 – 116 ]. Therefore, we are focusing primarily on CS for LSF stimuli, although we will also examine effects for high SF (HSF) stimuli, given that some studies indicate a schizophrenia-related impairment in HSF processing as well [ 117 , 118 ]. Because features within LSF stimuli are relatively large, there is less of an effect of visual acuity on their detection, as opposed to fine-grained HSF stimuli, the detection of which relies rely heavily on acuity.…”

It is now well documented that schizophrenia is associated with impairments in visual processing at all levels of vision, and that these disturbances are related to deficits in multiple higher-level cognitive and social cognitive functions. Visual remediation methods have been slow to appear in the literature as a potential treatment strategy to target these impairments, however, in contrast to interventions that aim to improve auditory and higher cognitive functions in schizophrenia. In this report, we describe a National Institute of Mental Health (NIMH)-funded R61/R33

“…Зрение, безусловно, нарушается при шизофрении: у четверти пациентов наблюдаются зрительные галлюцинации, две трети сообщают об иллюзиях и многие также демонстрируют объективные нарушения в организации восприятия [13]. Многочисленные исследования показали, что дисфункция зрительной системы при шизофрении наиболее выражена у пациентов с плохим преморбидным социальным функционированием, повышенным уровнем дезорганизации и/или плохим исходом [14].…”

Современные данные свидетельствуют о нарушении обработки информации при шизофрении не только на центральном, но и на периферическом уровне работы анализаторов. Приведенные в статье материалы подтверждают нарушение восприятия уже на уровне первых нейронов сенсорных анализаторов. Головной мозг получает неверные (ошибочные) посылы, на основе которых делаются неверные (ложные) заключения. И эти не соответствующие истине выводы могут экстраполироваться на разные суждения, что приводит к формальным нарушениям мышления пациентов и лежит в основе продуктивных симптомов шизофрении. Схожие нарушения в обработке информации в разных анализаторах указывают на повсеместный дефицит при шизофрении на всех уровнях прогнозирующего кодирования в разных областях головного мозга. Таким образом, распространенность изменений практически во всех областях головного мозга у больных шизофренией, вероятно, указывает на раннее возникновение данной патологии.
