Gradle Lecture: Uveal melanoma: Millimeters, personalized prognosis, and new therapies

ABSTRACT:  The management of uveal melanoma is going through tremendous transition into the realm of early detection, personalized prognostication and potentially new systemic and local therapies.  In the Harry S. Gradle Lecture, we will discuss four topics relevant to current melanoma management including (1) the importance of detection of small melanoma where thickness is approximately 3 mm or less, (2) optical coherence tomography angiography (OCTA) of melanoma before and after plaque radiotherapy, (3) DNA analysis of >1000 cases of uveal melanoma and the ability to personally prognosticate each patient based on cytogenetic profile, and (4) new systemic and local therapies.


The Gradle Lecture was established in 1948 in memory of Harry S. Gradle, MD, co-founder of the PAAO.  The lecturer exemplifies excellence and promotes best practice in education, positive relationships between the training program and the community, and has been an advocate and leader in the field of Ophthalmology.

Dr. Carol Shields completed her ophthalmology training at Wills Eye Hospital in Philadelphia in 1987 and subsequently did fellowship training in ocular oncology, oculoplastic surgery, and ophthalmic pathology. She is currently Co-Director of the Oncology Service, Wills Eye Hospital, and Professor of Ophthalmology at Thomas Jefferson University in Philadelphia.  Read more…

Peruvian Society of Ophthalmology Lecture – Fifty Years of Corneal Ulcers Management

ABSTRACT: Corneal ulcers have been and still are problems that appear with some frequency in our daily practice.  The agents vary widely, bacteria, virus, fungi, parasites, degenerations, immune reactions.  We will present how management of corneal ulcers have evolved since 1967 to date.  We will take account of the etiology, the exams taken, the different medical and surgical treatments, hoping I have provided an historical and practical vision of our experiences.

The National Society Lecture is given by a distinguished ophthalmologist representing the Congress host country and its national society. This tradition started with the National Society Lecture given at the first Pan-American Congress in 1940.

Former Professor of Ophthalmology at Cayetano Heredia Peruvian University, former tutor of the Ophthalmology residency for the National University Federico Villarreal at the Peruvian National Eye Institute (INO). Read more…

AJO Lecture: Diabetic Macular Edema: Past, Present and Future Treatments

Changes in diet and lifestyle throughout the world are fueling the current diabetic epidemic. Currently there are over 415 million people diagnosed with diabetes mellitus. Diabetic macular edema (DME) is the most common cause of moderate visual loss in diabetic patients. Since the mid 1980’s, macular laser photocoagulation has been proven to decrease the visual loss from DME. New imaging modalities like spectral domain optical coherence tomography have facilitated the diagnosis and follow-up of eyes with DME. Advances in molecular biology over the past decades have identified vascular endothelial growth factor (VEGF) and other inflammatory cytokines as pharmacologic targets for DME. VEGF inhibitors were developed and are currently considered the treatment of choice in most parts of the world. For it to be effective, anti-VEGFs need to be injected 8-9 times during the first year and 4-5 times in the second year. Despite this intensive treatment, close to 50% of eyes with DME do not respond to anti-VEGF agents and require macular laser photocoagulation. Corticosteroids have also been shown to be effective in treating DME, albeit at a cost of increased intraocular pressure and cataract formation. Subthreshold macular laser has been explored as a possible adjunct in lieu of conventional laser photocoagulation. Pars plana vitrectomy may be indicated in selected cases of DME where vitreomacular traction and epiretinal membranes contribute to DME formation. New pharmacological agents that target molecular pathways such as the angiopoietin Tie system, Src kinase, C-raf kinase, RTP 801, integrins, chemokines and lipoprotein associated phospholipase A 2 are in different stages of development.

Established in 1969, the AJO Lecture is one of the lectures that are traditional at PAAO congresses.  Dr. Frank Newell, Editor of the AJO, worked with the PAAO Executive Board to establish the AJO Lecture.  Dr. Benjamin Boyd, was PAAO Executive Director.   The AJO Editorial Board selects the lecturers and presents the lecturers with an AJO plaque.

Following the completion of his undergraduate studies at Cornell University, where he graduated with distinction in all subjects, Dr Wu went on to Tulane University School of Medicine to pursue his medical education. During this time  he was awarded a Pew Research Fellowship Read more…

The Moacyr E. Alvaro Pan-American Lecture: Global trends in Diagnosis, Treatment and Prophylaxis of Infectious Endophthalmitis – Leaning from the outbreaks

Acute-onset postoperative endophthalmitis after cataract surgery and intraocular injections of Anti-VEGF remains an important cause of visual loss despite the knowledge of microbial diagnosis, antibiotic administration and susceptibility tests.

The aim of this lecture is to challenge the audience to decide the best option with the knowledge available nowadays about the prophylaxis, diagnosis and treatment of infectious endophthalmitis.

This discussion is very important because the incidence, etiological agents, types of prophylaxis and available medications vary in different geographical regions, since there is no worldwide consensus regarding each of these subjects.

An overview of the current practice patterns regarding prophylaxis around the world can improve our knowledge on this subject and can help those undecided ophthalmologists in choosing a specific regimen. There are various prophylactic methods for ocular infections that have to be included in the care of patients. One of the main issues in this discussion is always the use of topical and intraocular antibiotics. Some studies on antibiotic sensitivity and ocular penetration of the drugs with good methodology can support the choice of the antibiotic class to be used as a prophylactic agent.

Considering that intracameral antibiotics are not commercially available in all countries, we should consider the evaluation of the compounding pharmacy in preparing these formulations and the risks of this practice.

The many prophylaxis strategies presented illustrate the wide variety of guidelines followed around the world. This variability may be related to economic factors, the availability of certain antibiotics, local standards of care, and surgeon preferences.

This lecture will include the evaluation of published endophthalmitis outbreaks to understand the most common risk factors and to correlate them to the prophylaxis used, etiological agents, antimicrobial sensitivities and treatment options. The medical diagnosis related to the various etiological agents can improve the initial treatment of those cases where cultures are not available.

Laboratory diagnosis of endophthalmitis is also always a challenge. Improvements in molecular diagnosis change the positivity of cases studied, and these new methods have been incorporated by microbiology laboratories that study endophthalmitis cases. In outbreaks of infectious endophthalmitis, molecular diagnosis is also important besides the positivity of cultures, and the decision of which molecular tests should be used to identify the isolated microorganisms. Predominant ocular flora and bacterial resistance may differ in different locations and also have to be analyzed.

Information related to treatment options for non-resistant and resistant organisms are available in the literature and a critical evaluation of this data will be discussed.

Therefore, prophylaxis, diagnosis and treatment patterns continue to evolve as newer studies report data on alternative approaches.

The Pan-American Lecture was established in 1995 and is traditionally presented by the most recent Past President of the Pan-American Association of Ophthalmology. In 2006 it was changed to be the Moacyr E. Alvaro Pan-American Lecture to honor Dr. Alvaro as one of the founders of the PAAO in 1939.
