Gareth Lema, MD, PhD

Gareth Lema, MD, PhD I am a retina physician and surgeon, certified by the American Board of Ophthalmology. I have the following goals for this page:

1.

The views expressed on this page are entirely my own and do not reflect those of my employers. I developed this page to better reach out to my patients in an informal setting. to share information about advances in retinal research - including interesting studies or my own publications.

2. to provide a forum for patients to ask me general questions - keep in mind this is a public page and so any

thing you write can be read by anyone. Also, this site should not be used to communicate with me in emergency situations.

3. to provide general advice about eye health and safety.

4. to provide information about my practice at Mount Sinai, New York Eye and Ear, and the Bronx VA. Please feel free to post comments or ask questions. At times I may not respond right away, but I am eager to hear from you and grow this page into an open forum.

I got to enjoy this beautiful day in DC with an early morning run. You can't beat the scenery and I even found a good cause to support along the way. Remember to get outside and advocate for yourself with regular fitness!

I love this public art adorning an overpass at 181st street. I can't remember why it was done, or by whom. But it really brought some joy to see its finer details while on a longer than usual run. (Because the sun was blocked by buildings early this AM, I used the AI feature in Google photos to brighten some of the images.)

I'm no influencer, but to those who are trying to be, please represent the best of our profession. I see cheap laughs at patients' expense sometimes and It makes me cringe. It's never harmless. Patients come to us at times of need and they have to trust that their best interests run through our hearts and souls. I got into this job to exemplify the best of humanity. I believe all my colleagues feel that way too.

This is awesome. I'm so happy THE PITT chose to highlight eye strokes (CRAO to us ophtho geeks). For a time-sensitive diagnosis like CRAO, it is exposure like this that makes the biggest difference! If you have sudden vision loss without pain, it might be an eye stroke or other serious condition!

(I hope the show creators don't mind me posting these pics...everyone see The Pitt on HBO. This issue was characterized very accurately, even if the center you go to has a slightly different diagnostic algorithm.)

What incredible dominance by these two goalies. Congrats to USA Hockey! And much respect to the historic runs made by the men's and women's teams this year.

Thanks to Sarwar Zahid, MD, who featured our eye stroke protocol on his podcast, Retfix and Chill!

Dr. Gareth Lema, MD, PhD joins Retfix and Chill to discuss the new paradigm shifts in managing CRAOs using intra-arterial tPA.

This is an under-recognized cause of vision loss. Bungee cords used for moving (the ones with the hooks) have caused some of the worst eye injuries I have ever seen. And many times, surgery cannot fix them.

Exercise band and bungee cord-related eye injuries are far from freak accidents. We’re glad to hear Indianapolis Colts QB Anthony Richardson Sr. is recovering from surgery following his mishap with a recoiling exercise band. You should know that it’s not always obvious when you’ve sustained a serious eye injury after a bungee cord or exercise band snaps back in your face. Read more here: https://ow.ly/qnY550XSFaM
