| description | Objective: Our study aims to provide a novel framework for the continuous
evaluation of stereoacuity under ambient lighting conditions using Bayesian
inference.
Methods: We applied a combination of psychophysical and expected entropy
minimization procedures for the computation of a continuous stereoacuity
threshold. Subsequently, we evaluated the effect of ambient lighting during
stereoacuity testing (ST) by adopting a bisection-matching based adaptive gamma
calibration (AGC). Participants ($N=187$) including visually healthy controls
($N=51$), patients with Intermittent Divergent Squint (IDS; $N=45$), and
controls with induced anisometropia (IA; $N=91$) performed ST with and without
AGC under two lighting conditions: completely dark (20 cd/m$^2$) and normally
lit (130 cd/m$^2$) rooms.
Results: Our framework demonstrated "excellent" reliability ($> 0.9$) and a
positive correlation with TNO (a clinical stereo test), regardless of whether
AGC was conducted. However, when AGC is not performed, significant differences

(Friedman $X_{r}^{2} = 28.015$; $p<0.00001$; Bland-Altman bias: 30 arc-sec)
were found in stereoacuity thresholds between dark and light conditions for
participants with IDS and IA. Controls are unaffected by AGC and yield a
similar stereoacuity threshold under both lighting conditions.
Conclusion: Our study proves that stereoacuity threshold is significantly
deviated particularly in participants with IDS or IA stereo-deficits if ambient
lighting is not taken into consideration. Moreover, our framework provides a
quick (approximately 5-10 minutes) assessment of stereoacuity threshold and can
be performed within 30 ST and 15 AGC trials.
Significance: Our test is useful in planning treatments and monitoring
prognosis for patients with stereo-deficits by accurately assessing
stereovision.</description><identifier>DOI: 10.48550/arxiv.2406.18336</identifier><language>eng</language><subject>Computer Science - Human-Computer Interaction</subject><creationdate>2024-06</creationdate><rights>http://creativecommons.org/licenses/by-nc-nd/4.0</rights><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>228,230,780,885</link.rule.ids><linktorsrc>$$Uhttps://arxiv.org/abs/2406.18336$$EView_record_in_Cornell_University$$FView_record_in_$$GCornell_University$$Hfree_for_read</linktorsrc><backlink>$$Uhttps://doi.org/10.48550/arXiv.2406.18336$$DView paper in arXiv$$Hfree_for_read</backlink></links><search><creatorcontrib>Lohia, Kritika</creatorcontrib><creatorcontrib>Soans, Rijul Saurabh</creatorcontrib><creatorcontrib>Saxena, Rohit</creatorcontrib><creatorcontrib>Gandhi, Tapan Kumar</creatorcontrib><title>An interactive framework for the evaluation and detection of stereoacuity threshold under ambient lighting</title><description>Objective: Our study aims to provide a novel framework for the continuous
