“…Table 4 presents the key group mean Visagraphic oculomotor-based parameters, including reading rate as described above. Grade-level efficiency significantly increased following the OMT by over 2 grade levels, which is considered to be clinically significant (Ciuffreda et al, 2003). Similarly, the number of fixations per 100 words (i.e., number of progressive saccades) reduced significantly.…”

“…It consists of an infrared, limbal-reflection eye movement recording system, which has become a standard clinical test in optometry (Ciuffreda & Tannen, 1995), to assess oculomotor-based reading dysfunctions objectively (Ciuffreda et al, 2003). The system has a resolution of <1 • , a sampling rate of 50 Hz, and a linear range of at least ±10 • .…”

“…They read silently the standardized 100-word text binocularly at their habitual reading distance in primary position. Following two practice paragraphs at level 10 to assure the attainment of a stable baseline (Ciuffreda et al, 2003;Griffin & Grisham, 2002), each subject then silently read a new level 10-paragraph at each test session, and they then answered 10 yes/no questions related to details of the paragraph to assess for adequate comprehension (≥70%) (Taylor, 1966). Subjects were instructed to read the paragraphs using their normal reading strategy, and furthermore to pay attention to text details, as they were tested for comprehension at the end of reading, but not to reread.…”

BACKGROUND: Considering the extensive neural network of the oculomotor subsystems, traumatic brain injury (TBI) could affect oculomotor control and related reading dysfunction. OBJECTIVE: To evaluate comprehensively the effect of oculomotor-based vision rehabilitation (OBVR) in individuals with mTBI. METHODS: Twelve subjects with mTBI participated in a cross-over, interventional study involving oculomotor training (OMT) and sham training (ST). Each training was performed for 6 weeks, 2 sessions a week. During each training session, all three oculomotor subsystems (vergence/accommodation/version) were trained in a randomized order across sessions. All laboratory and clinical parameters were determined before and after OMT and ST. In addition, nearvision-related symptoms using the Convergence Insufficiency Symptom Survey (CISS) scale and subjective visual attention using the Visual Search and Attention Test (VSAT) were assessed. RESULTS: Following the OMT, over 80% of the abnormal parameters significantly improved. Reading rate, along with the amplitudes of vergence and accommodation, improved markedly. Saccadic eye movements demonstrated enhanced rhythmicity and accuracy. The improved reading-related oculomotor behavior was reflected in reduced symptoms and increased visual attention. None of the parameters changed with ST. CONCLUSIONS: OBVR had a strong positive effect on oculomotor control, reading rate, and overall reading ability. This oculomotor learning effect suggests considerable residual neuroplasticity following mTBI.

“…This increased saccade ratio is in agreement with the multiple, excessive saccades found by Ron et al [4] in six out of 10 individuals with TBI, which normalized 4-9 months later. In addition, the clinically-based Visagraph system, which is a common clinical test for the objective assessment of reading and oculomotor-based reading-related parameters [21], indicated a reduced reading rate (mean 183 wpm), as well as an increased number of fixations (mean 122) and regressions (mean 24), from the norm for grade-10 reading material in these nine adult individuals with mTBI [19]. This result was consistent with the finding of Kapoor et al [12], who reported similarly abnormal Visagraphic reading eye movement findings in one patient with mTBI.…”

Vision and Reading Deficits in Post-Concussion Patients: A Retrospective Analysis

The prevalence of vision deficits in the pediatric/young adult concussion population in the private optometric practice setting remains unknown. Thus, a retrospective chart review in this area was conducted in the practice of the first author. Twenty-five consecutive patients with a medical diagnosis of concussion received a comprehensive vision and ocular health examination, which also included an objectively-based Visagraph reading assessment and clinical vergence/accommodative facility testing. Three primary categories of oculomotor-based deficits were found: convergence insufficiency (56%), accommodative insufficiency (76%), and oculomotor-based reading dysfunctions (68-82%). The most common symptom was headaches (84%), with 25% of the symptoms related to reading. 68% (15/22) were categorized as reading at least 2 grade levels below their current school grade level for reading eye movements based on the Visagraph findings. These overall findings are consistent with the general oculomotor-based/reading findings in the concussion/mTBI literature. The present results have important practical ramifications regarding the importance of preconcussion baseline oculomotor and Visagraph testing, as well as post-concussion follow-up testing, to help assess a student's ability to return-to-learn (RTL).
