Retinopathy of prematurity (ROP) and cerebral visual impairment (CVI) are among two major causes of childhood blindness and visual impairment in industrialized nations, and large countries with emerging economies are seeing increasing childhood blindness from ROP alone, adding to the burden of disease worldwide. The purpose of this paper is to review the long-term impacts of prematurity, ROP and CVI on vision in children who were born preterm.</p><p><strong>Method: </strong>The topics in this review of the literature include the burden of vision loss in prematurely born children world-wide, a description of ROP and CVI, effects on visual acuity, refractive errors, strabismus and binocularity, visual fields and contrast sensitivity, and risk factors for visual complications.</p><p><strong>Results: </strong>Children who are most at risk of visual complications are those with the smallest gestational age at birth and birth weight in general. Although ROP severity and the presence of neurological impairments including CVI play a large role in the development of poor visual outcomes, premature birth alone without CVI or severe ROP increases the risk of future visual complications.

There are several pathologies that can induce visual impairment, such as severe anisometropia, congenital unilateral cataract, corneal opacity, retinal diseases, and optic nerve anomalies. Sensory strabismus may be horizontal or vertical or a combination of them; however, most reports indicate the development of horizontal deviation as sensory strabismus. Regardless of the direction of the sensory strabismus, early diagnosis and management of the underlying pathology are important before strabismus treatment. The primary treatment approach for patients with sensory strabismus is surgery to correct ocular misalignment and straighten the eyes. This can help to improve the patients' symptoms and diminish the negative psychosocial impacts. In this article, we review the underlying etiologies and background pathologies associated with sensory strabismus. In addition, we investigate the determinant factors of the direction of sensory strabismus and its management strategies.</p>","PeriodicalId":37288,"journal":{"name":"Journal of Binocular Vision and Ocular Motility","volume":"74 1","pages":"32-40"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139991435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Convergence excess esotropia may be classified according to the AC/A ratio into two subtypes: accommodative type and non-accommodative type. Bifocal glasses are a suitable option for the management of patients with a high AC/A ratio and for the hypoaccommodative type. However, the overall success rate with bifocals is still low even in selected patients. Surgery is often eventually needed for most patients with convergence excess esotropia. Surgical options that do not directly address the variability of the angle of deviation entail medial rectus recession with the target angle based on the distance deviation, the near deviation, an augmented formula based on an intermediate angle, or on a prism adaptation test. Surgical options that directly address the variability of the angle include partial myotomy, medial rectus muscle posterior scleral fixation with or without recession, pulley fixation, slanting recession, Y-splitting, or combined recession-resection of the medial rectus muscle.

As an increasing number of patients seek medical advice on social media online, understanding patients’ activity regarding strabismus on Reddit will help assess their concerns and guide patient education. Methods A cross-sectional study of Reddit posts (www.reddit.com/r/strabismus/) was conducted from July 2021 to July 2022. Posts were sorted by date, type, content, emotional tone, and users’ sex and age (when available). Results A total of 709 posts were analyzed. Of the 164 (23%) posts in which users identified sex, 85 (52%) were female. The average age of patients to whom the post regarded was 23.7 ± 11.4 years (range 1–60 years). The most common content was surgical treatment (453, 63.9%), non-surgical treatment (263, 37%), seeking a diagnosis of their condition (190, 26.8%), and sharing personal journeys (136, 19.2%). Of the 289 (41%) posts that conveyed a clear emotional tone, the most common were anxiety (48, 18.3%), happiness (31, 11.8%), insecurity (24, 9.2%), frustration (22, 8.4%), and excitement (22, 8.4%). “Anxiety” posts had a significantly greater association with pre-surgery concerns whereas “happy” posts had a significantly greater association with post-operative updates (p = .003). Conclusions Patients with strabismus who post on Reddit tend to be young adults interested in surgical treatment options. Although the pre-operative tone was anxiety, post-operative posts tended to be happy.","PeriodicalId":37288,"journal":{"name":"Journal of Binocular Vision and Ocular Motility","volume":"4 1","pages":"160 - 164"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139324579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
