Three-Part Question:
In [patients with suspected Retinal Detachment, Posterior Vitreous Detachment or Vitreous Haemorrhage presenting to the Emergency department] is [ocular ultrasound] along with standard ocular examination [highly sensitive and specific] for diagnosis?
Clinical Scenario:
An adult male presents to the ED with flashes and floaters, and a curtain falling across the eye. Following standard ocular examination, there is a suspicion of RD, PVD or VH.
Could ocular ultrasound performed by an ED physician help in confirming the diagnosis and accelerate his further management?
Search Strategy:
The following databases/ search engines were queried:
1.tMEDLINE 1951 to date
2.tCOCHRANE Library
3.tGoogle scholar

Terms used:
1.tMEDLINE; exp *ULTRASONOGRAPHY/; 101402 results.
2.tMEDLINE; exp *RETINAL DETACHMENT/di [di=Diagnosis]; 643 results.
3.tMEDLINE; exp *VITREOUS DETACHMENT/di [di=Diagnosis]; 41 results.
4.tMEDLINE; exp *VITREOUS HEMORRHAGE/di [di=Diagnosis]; 55 results.
5.tMEDLINE; 2 OR 3 OR 4; 720 results.
6.tMEDLINE; 1 AND 5; 44 results.
We used the same terminology for other search engines.
Search Details:
A total of 44 papers were retrieved, of which 7 were found relevant to all parts of question. Additionally 5 studies by the radiology and ophthalmology departments reporting on the sensitivity of US in diagnosing ocular pathologies have been included.
Outcome:
There isn’t any level 1or 2 evidence available in the literature relevant to my three part question but the available evidence does show that ocular US is highly sensitive to diagnose RD, PVD and VH in the EDs.

Bottom Line:
There isn’t any level 1or 2 evidence available in the literature relevant to my three part question but the available evidence does show that ocular US is highly sensitive to diagnose RD, PVD and VH in the EDs.
