“…Our findings of TBI-associated visual dysfunction are supported by others who have also documented visual disturbances and abnormal oculomotor and binocular system measurements after TBI [22,[39][40]. Research has shown that BV problems are associated with a number of symptoms that can affect daily functioning including headaches, eye fatigue, asthenopia (eye strain), and reading problems [41][42]. Difficulties with reading can have negative effects on educational and vocational achievement, goals of many veterans returning from deployment.…”

Visual function, traumatic brain injury, and posttraumatic stress disorder

Abstract-Traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) are signature injuries of the Iraq and Afghanistan conflicts. The conditions can be comorbid and have overlapping signs and symptoms, making it difficult to diagnose and treat each. TBI is associated with numerous changes in vision function, but vision problems secondary to PTSD have not been documented. To address this shortcoming, we reviewed the medical records of 100 patients with a history of TBI, noting PTSD diagnoses, visual symptoms, vision function abnormalities, and medications with visual side effects. Forty-one patients had PTSD and 59 did not. High rates of binocular vision and oculomotor function deficits were measured in patients with a history of TBI, but no significant differences between patients with or without PTSD were evident. However, compared to patients without PTSD, patients with PTSD had more self-reported visual symptoms in all four assessments and the complaint rates were significantly higher for light sensitivity and reading problems. Together, these findings may be beneficial in understanding vision problems in patients with TBI and PTSD as comorbid conditions compared with those with TBI alone.

“…The literature has several validated surveys that are useful for measuring the symptoms associated with visual discomfort, such as those developed by Conlon et al (4) , the Convergence Insufficiency Symptom Survey (CISS) (5) , and the CDQOVL visual quality of life survey (6) . The CISS survey addresses the most common issues regarding near vision problems and has been subjected to numerous studies to determine its validity, reproducibility, and effectiveness in identifying and monitoring the treatment evolution in individuals with convergence insufficiency (5,(7)(8)(9) . Initially developed by the CIRS (Convergence Insufficiency and Reading Study) group, it was later modified to include near vision activities for adults (e.g., video games, hobbies, reading, and leisure activities) (5,7,8) .…”

Projecto n o CE-FCS-2012-027 -Faculdade Ciências da Saúde -UBI. ABSTRACTPurpose: Translate and adapt the Convergence Insuficiency Symptom Survey (CISS) questionnaire to the Portuguese language and culture and assess the psychometric properties of the translated questionnaire (CISSvp). Methods: The CISS questionnaire was adapted according to the methodology recommended by some authors. The process involved two translations and backtranslations performed by independent evaluators, evaluation of these versions, preparation of a synthesis version and its pre-test. The final version (CISSvp) was applied in 70 patients (21.79 ± 2.42 years) students in higher education, and at two different times, by two observers, to assess its reliability. Results:The results showed good internal consistency of the CISSvp (Cronbach's alpha -α=0.893). The test re-test revealed an average of the differences between the first and second evaluation of 0.75 points (SD ± 3.53), which indicates a minimum bias between the two administrations. The interrater reliability assessed by intraclass correlation coefficient ranged from 0.880 to 0.952, revealing that the CISSvp represents an appropriate tool for measuring the visual discomfort associated with near vision tasks with a high level of reproducibility. Conclusions: The CISS Portuguese version, showed good psychometric properties and has been sown to be applicable to the Portuguese population, to quantify the visual discomfort associated with near vision, in higher education students.

ÖzetAmaç: Bu çalışmanın amacı, normal binokuler görmesi olan Türk popülasyonunda, konverjansın yakın kırılma noktasını değerlendirmek ve farklı yaş gruplarında konverjansın yakın kırılma noktası için normatif verileri elde etmekti. Ge reç ve Yön tem: Bu ileriye dönük çalışmada, normal binokuler görmeli 329 kişi (yaş aralığı 3-72 yıl) değerlendirildi. Konverjansın yakın kırılma noktası ölçümü akomodatif bir hedef ile, 4 kere tekrarlandı. Bu yaş grupları (≤10, 11-20, 21-30, 31-40, 41-50, 51-60, and >60 yaş) için konverjansın yakın kırılma noktasının ortalama değerleri sağlandı. Yaş grupları arasındaki bu değerlerin istatistiksel karşılaştırılması (tek yol ANOVA ve Post hoc testi) oluşturuldu. Konverjansın yakın kırılma noktası ile yaş arasındaki ilişki Pearson's korelasyon testi ile değerlendirildi. So nuç lar: Ortalama konverjansın yakın kırılma noktası değerleri 2,46±1,88 (0,5-14) cm idi. Spesifik olarak bütün kişilerdeki ölçümlerin %95'i 6 cm'nin altındaydı. ≤10 yaş grubu ile 21-30, 31-40, 41-50, 51-60, >60 yaş gruplarının konverjansın yakın kırılma noktası değerleri arasında istatistiksel olarak anlamlı fark vardı (p=0,0001, p=0,0001, p=0,006, p=0,001, p=0,004). Konverjansın yakın kırılma noktasındaki artma ile yaşın artması arasında zayıf pozitif korelasyon gözlendi (r=0,355) (p<0,001). Tar t›fl ma: Göreceli olarak geniş çalışma popülasyonundan sağlanan bu değerler, normal binoküler görmeli Türk Popülasyonunda konverjansın yakın kırılma noktası için yaşla ilintilendirilmiş olarak örnek oluşturabilecek veri tabanını ortaya koymaktadır. Bu veri tabanı önceden rapor edilmemiştir. ( Sum maryPur po se: The purpose of this study was to evaluate the near point of convergence break in Turkish population with normal binocular vision and to obtain the normative data for the near point of convergence break in different age groups. Such database has not been previously reported. Ma te ri al and Met hod: In this prospective study, 329 subjects with normal binocular vision (age range, 3-72 years) were evaluated. The near point of convergence break was measured 4 times repeatedly with an accommodative target. Mean values of near point of convergence break were provided for these age groups (≤10, 11-20, 21-30, 31-40, 41-50, 51-60, and >60 years old). A statistical comparison (one-way ANOVA and post-hoc test) of these values between age groups was performed. A correlation between the near point of convergence break and age was evaluated by Pearson's correlation test. Re sults: The mean value for near point of convergence break was 2. 46±1.88 (0.5-14) cm. Specifically, 95% of measurements in all subjects were <6 cm. There were statistically significant differences, which were found between the age groups of ≤10 years old and 21-30, 31-40, 41-50, 51-60, >60 year-old age groups in the near point of convergence break values (p=0.0001, p=0.0001, p=0.006, p=0.001, p= 0.004). A mild positive correlation was observed between the increase in near point of convergence break and increase of age (r=0.355) (p<0.001). Dis cus si on: Th...
