Recent Keynotes, Conferences & Publications
I discuss how retina specialists can best address negative reviews and unfavorable comments on social media.
From the February/March 2020 issue of Retina Specialist, my latest Social Media Specialist column looks at the downsides of doctors on social media and how retina specialists can avoid the risks and pitfalls of putting their professional reputation online.
From the October 2019 publication of the Journal of VitreoRetinal Diseases, a special issue: Retina Young Investigators, you can find our study, Variables Associated With Culture-Positive Endophthalmitis After Intravitreal Injection of Vascular Endothelial Growth Factor Inhibitors.
Our work identifies predictive variables associated with culture-positive cases of acute endophthalmitis after vascular endothelial growth factor (VEGF) inhibitor injection.
From the November 2019 issue of RETINA SPECIALIST, you can find my Surgical Pearls column on surgical efficiency – Never use two steps when one will do: Step-saving tips when isolating rectus muscles and performing membrane peeling.
Twitter is the logical starting point for any physician or practice because anyone can read Tweets (although only registered users can post Tweets and comments).
You can find my latest Surgical Meditations column in the September 2019 issue of Retina Today – 1, 2, 3, 4, 5… How Many Trocars Do I Need for This Case? This surgical technique details five-port combined limbus-based vitrectomy and pars plana vitrectomy for complex vitreoretinal surgeries.
This handy technique can be use in eyes with anterior segment pathology impeding posterior segment view. Limbus-based vitrectomy with trocar-cannulas allows access to anterior segment pathology to clear the way for posterior segment maneuvers. In aphakic and pseudophakic eyes, the anterior infusion can be used throughout the case.
From the July 2019 issue of Retina Times, check out What’s News: ASRS Members Ride the Social Media Wave! This is a roundtable discussion with myself and Drs Brian Joondeph, Peter Karth & Rishi Singh. Here we ponder how a relevant social media presence can help build your practice and career.
On Friday 26 July 2019, I was part of the faculty for the Online and Social Media Content for Continuing Education and Marketing for the Retina Specialist course. This was held in Chicago, Illinois at the American Society of Retina Specialists (ASRS) 2019 Annual Meeting.
Engaging discussion and a real pleasure to share the stage with friends and colleagues Drs Jay Sridhar, Sunir Garg, Ajay Kuriyan and Audina Berrocal! As social media and online reputation continue to evolve in ophthalmology, and medicine as a whole, great to see the growing interest in this topic!
From the July 2019 issue of Retinal Physician, here is our surgical technique for maculopathy secondary to optic disc pit – Surgical Technique With Fibrin Glue for Optic Disc Maculopathy: An alternative that could aid in preserving retinal tissue.
This surgical technique is a viable approach to optic disc pit maculopathy that provides relatively rapid postoperative improvements in both function and anatomy.
“Surgery was the most difficult thing I could imagine. And so, I became a surgeon.” — Abraham Verghese, Cutting for Stone. This quote – along with the many chess games played with my sons – inspired this column found in the latest Retinal Physician issue.
From the opening, to the middle game, and to the final moves of the endgame, see how surgery is like chess! These surgical steps to success will help you down the right path.
Thanks Alcon and Retinal Physician for showcasing my surgical techniques in the July 2019 Surgical Maneuvers: Tip of the Month.
In it, I describe how retinal detachments are like onions! Learn how to peel off the layers of complex retinal detachments.
In this issue, I discuss Silicone Oil and the Goldilocks Principle: How to achieve the perfect silicone oil fill. Use of silicone oil tamponade during air-fluid exchange presents the risk of overfill or underfill. By setting a series of fail-safes, surgeons can achieve an optimum silicone oil fill while reducing the risk of overfill or underfill.
On 17 May 2019, I was part of the faculty of the 2019 University of Western Ontario Clinical Day in Ophthalmology in London, Ontario, Canada.

Grateful for the opportunity and many thanks to Dr Lulu Bursztyn and Dr Yiannis Iordanous for organizing a fantastic program!
Always a fantastic time with the Vit-Buckle Society! My talk this year – Above, In & Below: Onions and the layers of complex retinal detachments – was held on Saturday 6 April 2019 in Las Vegas, Nevada.
Complex surgical techniques is one of my favourite topics and it’s always fun to discuss this topic with so many top-tier surgeons!
Here is a case report entitled, Delayed Vision Recovery after Carotid Vascular Surgery for Branch Retinal Artery Occlusion (Jessica Ruzicki, Eric K Chin & David RP Almeida) published in the February 2019 issue of Case Reports in Ophthalmological Medicine.
Branch retinal artery occlusion (BRAO) is typically associated with irreversible vision and peripheral visual field loss. We report a case of a 62-year-old woman with a BRAO related to several cardiovascular risk factors. Our patient encountered gradual but significant vision recovery months following carotid artery endarterectomy for carotid stenosis.
From the November/December 2018 issue of RETINA TODAY, my new column SURGICAL MEDITATIONS discusses surgical techniques and shares pearls for both common and complex vitreoretinal topics. In the latest issue, I detail my preferred approach to drainage of choroidal hemorrhages and choroidal detachments. You can find the full article here.
From the October 2018 Ophthalmology Imaging Conference in Chicago, Illinois. My talk – Management of macula-involving choroidal granulomas – discussed multi-modality therapeutic options for inflammatory and infectious granulomas involving the macula. This case-based conference is one of the most interesting conferences filled with incredible pathology!
One of our recent publications is a unique case entitled, Atypical Presentation of Acute Macular Neuroretinopathy after Non-Ocular Trauma (Robin K Kuriakose, Eric K Chin & David RP Almeida) published in the January 2019 issue of Case Reports in Ophthalmology.
We report an atypical case of Acute Macular Neuroretinopathy (AMN) presenting with retinal hemorrhages and cotton-wool spots following non-ocular trauma.
AMN is a rare condition whose pathophysiological process remains speculative. Our atypical case supports the role of trauma in the pathophysiology of deep retinal capillary plexus compromise.
One of our latest study published in the Journal of VitreoRetinal Diseases – Infectious Endophthalmitis: Trends in Microbiology, Management, and Surgical Techniques. Many thanks to the Journal of VitreoRetinal Diseases for showcasing our review!

This study characterizes the clinical profile of patients who develop proliferative vitreoretinopathy (PVR) after rhegmatogenous retinal detachment (RRD) repair. Moreover, we developed a risk score model predicting visual acuity outcomes and identify unique variables predictive of PVR formation after RRD repair.
On Wednesday (25 July 2018), Dr Kunyong Xu presented our abstract, “Endophthalmitis After Intravitreal Injection of Vascular Endothelial Growth Factor (VEGF) Inhibitors: Management and Visual Outcomes” (Kunyong Xu, Eric Chin, & David Almeida). This recent publicationevaluates the management of patients who developed endophthalmitis after anti-VEGF injection. We reviewed a total of 258 357 intravitreal injections over the course of a 10-year period and found no difference in visual outcomes between initial treatment with immediate tap and injection of intravitreal antibiotics versus initial surgical pars plana vitrectomy.
Update from the 21st Annual Club Vit meeting @ Sea Island GA (June 27 – July 1, 2018).
Fantastic meeting with a wonderful group of colleagues and friends. Grateful to be part of this sun-loving retina crew.
On Saturday (June 30), I presented on endophthalmitis management and vision outcomes, looking at 10 years of intravitreal injection data.
Hot off the press! Check out our new publication in RETINA: Predictive Factors for Proliferative Vitreoretinopathy Formation After Uncomplicated Primary Retinal Detachment Repair by Xu, Chin, Bennett, Williams, Ryan, Dev, Mittra, Quiram, Davies, Parke, Boldt & Almeida.
We identify cigarette smoking and macular involvement as significant risk factors predictive of PVR formation after uncomplicated primary retinal detachment repair. Duration of retinal detachment symptoms, high myopia, lens status, lattice degeneration, location of retinal break, number of retinal breaks and surgical technique (e.g., scleral buckle with or without vitrectomy versus vitrectomy alone) were not found to be predictive of PVR formation.
Lots of news from Toronto, Ontario, Canada at the Canadian Ophthalmological Society (COS) Annual Meeting (May 31-June 3 2018). Wonderful to be part of the faculty for the Bimanual Anterior Vitrectomy course on Saturday June 2nd.
On Friday (1 June 2018), Dr. Parnian Arjmand won 3rd place in the 2018 COS Awards for Excellence in Ophthalmic Research Poster Competition!

Many thanks for all the interest and support!
One of our recent publications in OPHTHALMOLOGY: Endophthalmitis after Intravitreal Injection of Vascular Endothelial Growth Factor Inhibitors – Management and Visual Outcomes
We evaluated the management of patients who developed endophthalmitis after anti-VEGF injection. We reviewed a total of 258 357 intravitreal injections over the course of a 10-year period and found no difference in visual outcomes between initial treatment with immediate tap and injection of intravitreal antibiotics versus initial surgical pars plana vitrectomy.
Sincere thanks to The Ophthalmologist for publishing my article on the framework of Decision Diagnosis and how to apply the PACT strategy for effective decision making. You can find this in the February 2018 issue entitled, Decision Diagnosis: Making a PACT to avoid decision procrastination.
PACT refers to Practice, Assess, Collect and Triage. If you are struggling with decision making, then Decision Diagnosis can help you make a PACT.
Many thanks to The Ophthalmologist for publishing our article, When primary scleral buckling should be considered – and how to succeed (Alexander Ringeisen, Ed Ryan and David RP Almeida) in the February 2018 issue!
We go over why scleral buckling is still the treatment of choice for certain retinal detachments and which patients are the best candidates for a primary scleral buckle. The article is aimed at ophthalmology residents and vitreoretinal fellows and provides an overview when primary buckling should be considered and provide guidance on which techniques will help success, as well as when to avoid a primary buckle.
Many thanks to Clinical Ophthalmology for publishing our study, Epiretinal membrane and cystoid macular edema as predictive factors of recurrent proliferative vitreoretinopathy (Kunyong Xu, Eric K Chin, D Wilkin Parke 3rd & David RP Almeida).
In it, we describe epiretinal membrane and cystoid macular edema as potential predictive factors for recurrent proliferative vitreoretinopathy. Early recognition and treatment of these conditions may be critical to prevent dreaded recurrent postoperative scarring and improve visual outcomes.
Earlier this year we published a photo essay on intraocular foreign bodies in the Canadian Medical Association Journal (CMAJ). Entitled, Five things to know about intraocular foreign bodies (Kunyong Xu MD MHSc & David RP Almeida MD MBA PhD) – here is a quick summary:
1. Risk of intraocular foreign body is associated with mechanism of injury.
2. Ophthalmic examination should include dilation of the pupil.
3. Imaging should be conducted promptly to diagnose and localize intraocular foreign bodies.
4. Antibiotics should be prescribed early to prevent endophthalmitis.
5. Patients with an intraocular foreign body require urgent referral to an ophthalmologist.
From Barcelona, Spain, for the EURETINA Annual Congress, on Friday (8 September 2017), I presented a talk on our recent findings and techniques for proliferative vitreoretinopathy (PVR).
My talk, Predictive factors for proliferative vitreoretinopathy formation after uncomplicated primary retinal detachment repair (David RP Almeida, Kunyong Xu, Eric K Chin & D Wilkin Parke III) looked at predictive tools for patients who develop this complex condition.

This study provides further insight into the benefits of multi-modality therapy for diabetic macular edema, the most common cause of vision loss in working age individuals.
Check out one of our recent publications, Novel Technique for Submacular Hemorrhage Removal Using 27-Gauge Pars Plana Vitrectomy and Recombinant Tissue Plasminogen) Activator (Kunyong Xu MD MHSc, Eric K Chin MD, John B Davies MD & David RP Almeida MD MBA PhD). Many thanks to the Journal of VitreoRetinal Diseases for publishing our work!
Many thanks to the Journal of VitreoRetinal Diseases and the American Society of Retina Specialists for publishing one of our recent reports, West Nile Virus Chorioretinitis With Foveal Involvement: Evolution of Lesions on Optical Coherence Tomography (Gary L. Yau, Eric K. Chin, D. Wilkin Parke, Steven R. Bennett & David R. P. Almeida).
It was published in the March 2017 issue of the journal and describes the clinical course of foveal West Nile virus chorioretinitis.
Best practices for the injection technique of the dexamethasone intravitreal implant (Ozurdex). Many thanks to my wonderful colleagues – Seenu M. Hariprasad MD, Kimberly Drenser MD PhD, Sunir Garg MD and Bruce Saran MD – for involving me in this excellent discussion!
One of our most recent publications, Dysfunctional Autonomic Regulation of the Choroid in Central Serous Chorioretinopathy (C Nathaniel Roybal, Elisabeth Sledz, Yasser Elshatory, Li Zhang, David RP Almeida, Eric K Chin, Brice Critser, Michael D Abramoff & Stephen R Russell), was published in the June 2017 issue of RETINA.
We describe the effect of changing perfusion pressures on retinal and choroidal structure in central serous chorioretinopathy (CSC). In this study, we found that choroidal thickness increased in response to increased perfusion pressures in patients with CSC and not in normal controls. These findings likely represent an autonomic dysregulation of choroidal blood flow in patients with CSC.
Another one of our recent publications, Proliferative Vitreoretinopathy (PVR) Update: Current Surgical Techniques and Emerging Medical Management (Robin K Kuriakose, Kunyong Xu, Eric K Chin & David RP Almeida) published in the Journal of VitreoRetinal Diseases (April 2017).
In this detailed review, we provide an update on current surgical techniques and emerging medical
management in proliferative vitreoretinopathy (PVR). PVR is the number one cause of failed retinal detachment repair and a still relatively unexplained phenomenon. We, along with Citrus Therapeutics are working hard to find treatment for this challenging disease process.
Another of our recent publications, Myelinated retinal nerve fibre, myopia, and amblyopia syndrome (Kunyong Xu & David RP Almeida) published in the Canadian Journal of Ophthalmology (April 2017).
We describe the complex relationship among myelinated nerve fibre, myopia, and amblyopia. We present the case of a 6-year-old boy who presented with blurry vision of the right eye over 2 months. The visual prognosis in these cases is variable.
Fantastic to be part of the faculty at the Vit-Buckle Society V meeting in Las Vegas (6-8 April 2017).
I presented a talk on proliferative vitreoretinopathy (PVR), including pearls and techniques, for this challenging group of patients. Patients who are current or former smokers are significantly more likely to have PVR formation after retinal detachment repair.
Check out one of our most recent publications, Efficacy of the Intravitreal Sustained-Release Dexamethasone Implant for Diabetic Macular Edema Refractory to Anti-Vascular Endothelial Growth Factor Therapy: Meta-Analysis and Clinical Implications published in Ophthalmic Surgery, Lasers and Imaging Retina (February 2017, Volume 48, Issue 2, pages 160-166, DOI: 10.3928/23258160-20170130-10).
In this meta-analysis, we examined a total of 3,859 patients among 15 studies and found that treatment with Ozurdex is associated with significant mean improvement in visual acuity in patients with diabetic macular edema who have a sub-optimal response to anti-vascular endothelial growth factor therapy. This is further support to a multimodality approach to treating diabetic macular edema.
One of our recent publications, Deer Tick Masquerading as Pigmented Conjunctival Lesion (Robin K Kuriakose, Lorna W Grant, Eric K Chin & David RP Almeida). Thank you American Journal of Ophthalmology Case Reports for publishing our study.
In it, we report a unique case of tick penetration of a black-legged deer tick (Ixodes scapularis) into the conjunctiva. Despite the low risk for Lyme disease, doxycycline was prescribed for prophylaxis. In any case of suspected tick penetration to the ocular surface, immediate ophthalmologic consultation and prompt removal as well as attention paid to the Infectious Diseases Society of America guidelines regarding prophylaxis.
Thank you, Retina Specialist magazine, for showcasing our work on complicated viral retinitis retinal detachment repair in the November 2016 issue. This is part of our evolving work on approaches to complex retinal detachments.
One of our published surgical techniques for endophthalmitis. The study entitled, Five-Port Combined Limbal and Pars Plana Vitrectomy for Infectious Endophthalmitis, was published in Case Reports in Ophthalmology (2016;7:289–291). In it, we describe a surgical technique combining limbal based vitrectomy and pars plana vitrectomy to manage acute infectious endophthalmitis. You can find the study here.
Wonderful to be part of the faculty in Toronto for the 56th Annual Walter Wright Symposium, Retina 2016: A Practical Approach to Navigating the Future.

This study details a case of an immunosuppressed patient with active chorioretinitis and chronic endophthalmitis after cataract surgery.
Previously, I described our technique for retinal embolectomy. This technique was published in Retinal Cases & Brief Reports. Retinal embolectomy involves the removal of emobli from the retinal vasculature in selective cases of arterial occlusions.
Check out another one of our publications, Elevated intraocular pressure following pars plana vitrectomy due to trapped gas in the posterior chamber, published in Retinal Cases & Brief Reports (Fall 2016, Volume 10, Issue 4, pages 334–337).
Clinicians should be aware of elevated intraocular pressure secondary to trapped gas in the posterior chamber. Aspiration of the trapped gas can alleviate both pupillary block and angle closure without compromising gas tamponade.
On Friday, 14 October 2016, I presented a talk on our technique for retinal embolectomy at the American Academy of Ophthalmology (AAO) Retina Subspecialty Day in Chicago. Retinal embolectomy involves the removal of emobli from the retinal vasculature in selective cases of arterial occlusions.
