Slit lamp Puns

Can an optician tell between Aqueous Deficient Dry Eye and Evaporative dry eye with just coloured dye and a slit lamp exam, if the optician doesn't touch the eye/move the eyelid at all?

If there's a Weiss ring, great. But we know not all PVDs make Weiss rings. I realise there's something deficient in my technique bbecause I'm just never quite sure of the vitreous status until I have an OCT or ultrasound B scan image in my hands. I've seen people with less experience than myself quite confidently put in 'no PVD' in their notes, so I think this is a me problem I need to work on. Any tips, please?

I use my smartphone to take thousands of images/videos at the slit lamp. For the past 5 years, I've been doing it manually, holding my phone in the air to align the camera with the images from the eyepieces.

I'm seeking a better solution. I don't want to spend more than $100 on this.

Has anyone found a cheap adaptor (on eBay etc) which works well?

I'm hoping to hear from those with experience using the device.

Thanks in advance

I'm a 3rd year optometry student in the UK so about to finish the course and head into my pre-registration year. Every time I do a slit lamp BIO funuds exam with my Volk lens I always see two images - one image slit on the left with a black strip in the middle and the same image slit on the right.

The eye pieces are adjusted corrected for my PD and focused too so I can't figure out what it is! Anyone else had this problem - any solutions?

If it's relevant, I use the SuperField lens. Thanks!

Hi everyone, I'm currently looking at portable slit lamps. And just overwhelmed with the choice.
I'm debating between the Keeler PSL https://www.keelerusa.com/psl-portable-slit-lamp.html, which is better known and the Eidolon Slit lamp 510L https://www.slitlamp.com/510l (that a friend also recommended and is 10x cheaper). Thoughts? Or other recommendations?
Asking for an unbiased opinion XD

Hello, I am a second-year medical student with an interest in ophthalmology. I have a long-standing fourth nerve palsy that is asymptomatic except for when I try to fuse in a microscope. While I was precepting it wasn't until the 7th or 8th patient I was able to fuse the images (using a slit lamp) and even then it felt like if I was to look away I wouldn't be able to fuse again. Have you or any residents you know of ever dealt with something like this? Is it harder to fuse in a surgical scope (compared to a slit lamp)? I really like the specialty but I'm unsure if I can improve this technical deficiency with practice.

Looking for something relatively inexpensive that is practical for taking anterior segment, fundus, and gonioscopy photos with the cell phone camera. What do you guys use?

Hi, ophtho resident here. Our program is looking at investing in a smartphone fundus and /or ant seg camera for on call use. The price point would be under 500 dollars. Do any of you have recommendations for cameras that you use in your practice?

Thanks.

Hello! First year optom student, first time posting on this sub. Today in lab, we began practicing slit lamp examination on a very basic level. While my lab partner was practicing on me (the patient), I noticed I was able to see an image of what I assume was my own fundus? I could see faded vasculature and the reddish color of the retina. Why is this? What's the medical explanation for this phenomenon?

I am excited to finally introduce CornealAnalysis.com, a joint collaboration with Dr Shady Awwad and a free online medical app which allows eye specialists to transform a 2D slit lamp image of the eye into 3D and measure coordinates and surface area of points and lesions on the cornea, bridging clinical, mathematical and computer sciences.

It is a mobile, tablet, and desktop-friendly interface, with simple layout but multiple layers of functionalities to suit casual and advanced users alike. YouTube tutorials for all kinds of clinical applications will soon follow.

Applications include:

1. Custom Ablation Area PTK available on the Schwind Amaris
2. Measuring the exact rotated angle of a toric IOL or ICL
3. Computing angle alpha and kappa
4. Tracking epithelial defects or corneal lesion sizes
5. Assessing the position of a multifocal IOL
6. CAIRS and femtoAK post op evaluation
7. Triangulating reference points from pupil centroid to corneal vertex to any point, for epithelial PTK treatments, and many, many other clinical applications.

I'd love to hear your suggestions and comments on how to improve this software. My name is Jad Assaf and I'm a medical student and aspiring ophthalmologist. Your support means a lot!

Hello,

I'm a new Ophto resident and I was wondering which resources/videos helped you the most for retina exam on slit lamp and refraction?

I already have AAO's Practical Ophthalmology, and I've found it somewhat usefull. However for the retina exam I had much better results with asking older residents for tips than just reading a book.

So which videos helped you when starting out your residency?

Ever since we've started seeing patients with masks, I've had a lot of trouble with the slit lamp eyepieces fogging during exam. I've tried multiple masks and none have worked. Anybody else running into this problem? Any solutions?

There are a lot of products on the market, so I am wondering what is actually used in practice. I was also hoping to find something that can attach on and off easily.

Thanks!

I am a 25yo, currently final year med sch who is interested in pursuing an ophthalmology career in the future. I am doing my emergency department rotation now and I get to see quite a few eye cases so I have been using the slit lamp. However I am having trouble fusing the images/seeing double when using the slit lamp, even though I make sure that I am able to see through both sides with both eyes at the same time (I keep both eyes open, then close the left eye and able to see with right, then vice versa for the other eye). Is there a way to correct this/train such that I'm able to fuse the images? I think my left eye is more dominant than my right too, just wondering if it will affect fusion? Thank you!

So before using the slit lamp we should always focus the instrument.

However, when I try to focus each eyepiece individually, no matter how much I change the dial, the view always appears very clear to me. I do use a narrow slit beam.

So I'm not sure what I should be looking at or what's wrong. I'm guessing I can just keep the dial at 0D?

This might be a silly question, but is the slit lamp “hard” to use?
I ask because I’m a pre-optometry undergrad taking microbiology lab right now and I have trouble using the binocular compound light microscopes.
What I mean by "trouble" is that on high power (1000x), I find that my eyes get tired very quickly and occasionally I have double vision while using the microscope. Again, these are binocular microscopes. On low power (100x or 400x) I do not have this problem. 🙂 Also I find that low power dissecting microscopes are much easier for me to use, maybe because the field of view is wider and head position doesn’t matter as much  🤷‍♂️.

Anyway, as a pre-optometry student, I’m just really nervous that the slit lamp (because they're binocular) will be visually hard for me to use in the same way that high power binocular compound microscopes are.
I was really frustrated after lab this week because my eyes got extremely tired after using the microscopes for a 2 hour staining lab- on high power I felt like was looking down two reaalllly long tubes and it was hard for my eyes to "look far" enough for the image to remain fused. My eyes kept wanting to relax and "look close" which would break binocular alignment and I'd see two images instead of one.
I felt like such a dumbass because I couldn't get my eyes to cooperate with the microscope.

BTW, I wear + glasses for hyperopia, I had an intermittent eso eye turn as a child. I'm a 3.9 GPA student and optometry is my dream career...
