    Clinical Usefulness of a Computerized Vision Chart for Distance Stereoacuity Assessment in Children with Intermittent Exotropia
    (Taylor & Francis Inc, 2021) Ayyildiz, Onder; Yalinbas, Duygu; Ceylan, Osman Melih; Mutlu, Fatih Mehmet
    Introduction The aim of this study is to evaluate distance stereoacuity in children with intermittent exotropia (IXT) using a computerized vision chart (CVC), to compare the results to the normal subjects, and to determine if any correlation between stereoacuity and IXT severity exits. Methods A prospective case-control study was conducted including 24 children with IXT and 25 age-matched normal subjects. The mean age was 8.9 +/- 4.5 in IXT group and 9.4 +/- 4.2 in control group. The majority of patients (n = 17) had basic type IXT. Full ophthalmic examinations, deviations and stereoacuity tests were evaluated. Stereoacuity was measured with the CVC for distance stereoacuity and Randot stereotest book for near stereoacuity. Level of fusional control in patients with IXT was assessed using Newcastle Control Score (NCS). Seven of the patients with IXT were also reevaluated postoperatively. Results Near stereoacuity was good in both IXT and control groups, and there was no significant difference between groups. There was a poor correlation between near stereoacuity and NCS (r(s) = 0.15, p = .48). Distance stereoacuity in the IXT group was significantly reduced compared to controls (p = .004). There was a positive correlation between distance stereoacuity values and NCS in patients with IXT (r(s) = 0.73, p < .001). Conclusion Diminished distance stereoacuity in children with IXT can be detected with the CVC and this test may be useful for deciding the timing of surgical intervention and postoperative evaluation.

    Purpose: To compare the measurements of intraocular pressure (IOP) and central corneal thickness (CCT) by tono-pachymeter (CT-1P) with\rIOP measurements by Goldmann applanation tonometer (GAT), and CCT measurements by Pentacam.\rMaterials and Methods: Two hundred eighteen eyes of 109 patients were included in the study. Intraocular pressure measurements were\robtained by the CT-1P and GAT, whereas CCT measurements were obtained by CT-1P and Pentacam. Blant-Altman plots for agreement, and\rPearson correlation and interclass correlation (ICC) for reliability between the measurements were analyzed.\rResults: The mean IOPCT-1P, IOPCT-1P adj., IOPGAT were measured as 18.2±4.32 mmHg, 17.75±4.05 mmHg and 16.9±4.16 mmHg, respectively.\rThe mean CCT was measured as 554.8±37.3 ?m and 543.6±35.9 ?m with CT-1P and Pentacam, respectively. Mean differences between\rdevices were signifi cantly different in terms of IOP and CCT measurement (p<0.001, for all). Interclass correlation coeffi cient confi rmed the\rexcellent reliability between devices in terms of measurement of IOP and CCT (p<0.001, for all). The 95% limits of agreement (LoA) for IOP\rwere -4.24 to 3.28 mmHg between IOPCT-1P adj. and IOPCT-1P, -3.49 to 5.14 mmHg between IOPCT-1P adj. and IOPGAT and -2.7 to 5.3 mmHg between\rIOPCT-1P and IOPGAT. Also 95% LoA for CCT were -12.33 to 32.16 ?m between CCTCT-1P and CCTPentacam.\rConclusion: Although CT-1P overestimated both IOP and CCT measurements, the device had an excellent ICC with Pentacam and GAT in\rterms of CCT and IOP measurements. The ability of tono-pachymeters measuring both CCT and IOP with a single device provide an important\rconvenience in busy clinics.
