Here is a quick summary of far points and focal points. You can always think of + and - lenses "pushing" and "pulling" the image onto the retina but a more elegant view is lenses correcting vision by placing the secondary focal point on the eye's far point. #ophthalmology

Interesting case of torsional nystagmus this weekend. It looks like SO myokymia but the fast phase is excyclotorsion OD and incyclotorsion OS #ophthalmology #ophthotwitter #medtwitter

Follicular vs. Papillary Conjunctivitis can be challenging. For follicles, think Toxins, Viruses, and Chlamydia. For papillae, think everything else including pABillae (allergies and bacteria). #ophthalmology #ophthotwitter #medtwitter

Ophthalmology Eponym of the Week: Schlaegel Lines are streaks of pigmented curvilinear scars in the retinal periphery seen in multifocal choroiditis. This condition resembles POHS but look for vitritis to distinguish them. #ophthalmology #ophthotwitter #MedTwitter

The "grab 'n go" method to start a rhexis flap saves a trip in and out of the eye and a few moments. I'm not the fastest now but I'm excited to be learning these efficiency tips early. #ophthalmology #ophthotwitter #medtwitter

Beware the young patient with unilateral glaucoma and ask about history of trauma! Also don't forget the angle after hyphema/trauma. Angle damage and glaucoma are common complications. #ophthalmology #ophthotwitter #medtwitter

Ophthalmology Eponym of the Week: Kestenbaum's rule is that the reading add should equal the inverse of the visual acuity for patients with low vision. E.g., 20/200 = 200/20 = +10.00 ADD. #ophthalmology #ophthotwitter #medtwitter

First time really chopping. I think I love it because it probably can be faster than divide and conquer and my CDE was 0.50. Still need to get used to force vectors and aspirating non-debulked quadrants. Learning new skills is one of the most fun parts of the job! #ophthalmology

Asteroid hyalosis is a common entity of lipids, calcium, and phosphorus deposits suspended in the vitreous resembling an asteroid field. It's associated with DM and differenced from synchysis scintillans where the deposits float freely in the vitreous and settle. #ophthalmology
