Brief Summary:
The study is collecting data along with other academic institutions regarding the accuracy of ocular ultrasound in diagnosing retinal detachment.

Condition or disease Intervention/treatment Phase
Retinal Detachment Device: Ultrasound Not Applicable

Detailed Description:
This is a prospective, cross-sectional study to assess the utility of point of care ultrasound in the diagnosis of ocular complaints in the emergency department with specific focus on the accuracy of diagnosis when compared to that of a blinded ophthalmologist. Ocular complaints represent between 2% and 3% of ED visits (Walker et al, 2011). This percentage may include vision-threatening diagnoses including retinal detachment, which can occur in 3-4% of patients presenting with ocular complaints (Alotaibi et al, 2011). However, the equipment and expertise required to adequately assess for conditions such as retinal detachment are limited in busy emergency departments due to the time consuming and challenging nature of the examination. Incorporating the use of an ultrasound could provide a more available, focused, and timely assessment.

Arm Intervention/treatment
Experimental: Patients Receiving Ultrasound
Enrolled participants will receive a bedside ocular ultrasound of the affected eye and the ultrasound will be compared with the ophthalmologist diagnosis. The participant's medical record will also be reviewed for information regarding demographics, complications, and outcomes.
Device: Ultrasound
Each participant will receive an ocular ultrasound which poses minimal to no harm to the participant and the ultrasound results compared to final diagnosis.

Primary Outcome Measures :
  1. Ocular Ultrasound [ Time Frame: 10 minutes during the patient's visit will be towards obtaining consent and ultrasound evaluation ]
    Ocular ultrasound diagnosis will be compared to formal ophthalmology evaluation diagnosis
