RESUMO

Purpose: To better understand the sensory impact of retinal exam components typically experienced by infants undergoing various retinopathy of prematurity staging examinations, adults concerned for infant welfare and exam quality underwent similar exams to compare their perceived stress. Patients and Methods: Adults directly involved with ROP exams and infant stress reduction had cardiac monitoring and concomitant ordinal self symptom-score (1-10 Likert) during 15 components of the exam including lid speculum, various scleral depressors, indirect ophthalmoscopy, goniolens and direct ophthalmoscopy and retinal photography (Phoenix ICON) with or without topical anesthesia. Results: Nine adults provided impressions and cardiac rhythm gathered supine over 15 minutes. Pain score for topical anesthetic 2 was less than for tropicamide 4. Lid specula numb scored a median 2 level (from 1 to 10) pain but without anesthetic scored 6. The goniolens numb scored 3. Scleral depression numb scored 3-4 but increased to 7 without topical anesthesia. Direct ophthalmoscope scored 3 through the goniolens and the retinal camera scored 4 pain. Brightness with low 350 Lux indirect scored 6-8 numb and 9 brightness without anesthetic. Full bright indirect, direct ophthalmoscope and the retinal camera all had Lux of 3000-4000 and were scored brightness 9, 7 and 10, respectively. Adults had minimal oculocardiac reflex during on-globe retinal examination methods (range 98% to 102%). Conclusion: Topical anesthesia provided a moderate reduction in pain during on-globe lid-speculum, scleral depressed indirect examination. There was a synergistic augmented sensory response between pain and brightness. Adults did not show the bradycardia typically elicited by retinal examinations in premature infants.

RESUMO

Purpose: Existing and emerging visual acuity methods like dynamic and dichoptic presentation, preferential looking and eye tracking promise to afford better and earlier assessment in children with and without amblyopia so we propose methods needed to easily evaluate and compare their metrics. Subjects and Methods: Patients older than 8 years with treated amblyopia and superb vision (logMAR -0.1 to -0.3) normals performed timed, patched eETDRS with Sloan matching card at 3.00 m and PDI Check dichoptic near rivalry dynamic test to demonstrate test re-Test and compared disparate acuity with intraclass correlation (ICC) and Bland Altman 95% limits of agreement (LOA) to generate a simple method of qualifying acuity test matching. Results: 26 amblyopic patients and 11 superb-vision normals performed eETDRS retest, PDI Check retest and combined ICC of 0.98, 0.60 and 0.27, respectively, and Bland Altman LOA of 0.24, 2.06 and 2.28 logMAR. The time to test one eye with eETDRS had median (interquartile range; IQR) duration of 280 (205 to 346) seconds, while the PDI Check autostereoscopic dichoptic for both eyes only took 39 (30 to 47) seconds. Optimum ICC and LOA for visual acuity comparison should be >0.95 and <0.3 logMAR, whereas "good" ICC and should be 0.75-0.89 ICC and 1.0-1.49 logMAR LOA. Conclusion: Superb vision subjects (logMAR < -0.1) and treated amblyopic patients confirmed optimum comparable eETDRS, and fair test re-Test PDI Check but suppression on near dichoptic testing confirmed disparity compared to optimized eETDRS distance acuity.
