An observational study in Spasm of Accommodation, sponsored by Randa Farouk Kashif. Completed. Open to participants aged 18 Years to 35 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-08-31.
Sponsored by Randa Farouk Kashif · Observational
Detection if there is association between spasm of accommodation and smart phone abuse by ultrasound biomicroscopy on anterior segment of the eye
Group (A): 40 smart phone abuser subjects (According to the smartphone questionnaire).
Group (B): 40 smart phone non user subjects.
Exclusion Criteria:
Auto refractometer without cycloplegia Uncorrected visual acuity (logMAR conversion). Anterior segment slit lamp examination UBM examination settings :Supine decubitus position.5150 Vumax (Sonomed, USA) under standard illumination Parameters that will be measured: corneal thickness, anterior chamber depth, angle to angle distance, cornea-posterior capsular lens distance, lens thickness, pupillary diameter, angle of anterior champer and trabecular-ciliary process distance. Cycloplegic refraction UBM examination will be repeated after cycloplegia with the same settings. The patients found to have spasm of accommodation will be subjected to ways to relief the spasm of accommodation and repetition of UBM if possible
Diagnostic Test: Ultrasound Biomicroscopy of anterior segment of the eye
