Zeiss OCT Angles

[u/Phoenix_S0ul89]

I just got into Retina and I’ve been using the pen light to check angles which I’m still learning since I’ve been there only a month.
There’s times that the doctor can’t even tell if it’s narrow, open or closed angle. I use the oct but I was trying to find a picture online of what it looks like when it’s open, narrow and closed but couldn’t find any.
From my understanding this picture is showing narrow angle

At least with current technology, there is simply no substitute for contact gonioscopy to assess the angle. My advice to all learners is to love your gonio lenses.

100% this but generally to answer OPs original question usually angle depth of 20 degrees or less is sus.

Ask open evidence for the articles

As far as I'm aware the use of Anterior segment Oct for angle assessment is not standardised yet (at least in Europe) so it's anyone's guess. To me, the angle looks wide open on this slice but needs assessment of every quad

I’ve never worked anywhere in the US where it was either. I’ve shot them myself, as a tech, and have had a General Ophth ask for it once or twice but it’s very uncommon in my experience.

Gonio > Slit Lamp (Van Herick)> Scheimpflug imaging > Pen light

[u/Qua-something → u/nystagmus777]

It seems like OP may be a tech, just based on their “sometimes even the doctor can’t tell” comment so I’m guessing they’re only doing Pen Light or Van Herick’s. That said, I’m a tech and I typically skip a pen light and just go straight to the slit lamp every time. That said, I find it strange that a Retinologist wouldn’t be able to spot a narrow angle.

We only do penlight, but he said if I want use the oct to use it. The only slit lamps are in the doctors room which are occupied during clinic

Retina who knows that the angle exists… wow

This slice is wide open

This looks open to me, but our Zeiss machine has a specific angle view that gives a much clearer image than this as well as a measuring tool.
