He is a clinician-scientist who directs a research laboratory and conducts clinical trials. His laboratory research is directed at understanding the pathogenesis of ocular neovascularization and excessive retinal vascular permeability, and the mechanism of cone cell death in inherited retinal degenerations. He helped to determine the importance of vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1, and Tie2 in retinal and choroidal vascular diseases. The clinical trial group under Dr. Campochairo provided the first demonstration of the benefits of suppression of VEGF in diabetic macular edema and retinal vein occlusion. He has developed strategies for sustained suppression of VEGF that are currently being tested in clinical trials. Dr. Campochiaro trained at the University of Notre Dame, Johns Hopkins School of Medicine, and the University of Virginia. He did a vitreoretinal fellowship and research fellowships at Johns Hopkins and joined the faculty of the University of Virginia in 1984.

      Dr. Nara Lygia De Macena Sobreira is an assistant professor at the McKusick-Nathans Department of Genetic Medicine at Johns Hopkins University School of Medicine. Her area of expertise is rare Mendelian phenotypes, analysis of next-generation sequencing, and functional testing of candidate causative variants. She earned her M.D. at the University of Pernambuco in Brazil. She finished her Ph.D. in Human Genetics at Johns Hopkins followed by a one-year postdoc also at Johns Hopkins School of Medicine. During her Ph.D., she worked with Dr. David Valle using next-generation sequencing to elucidate the molecular basis of rare Mendelian phenotypes and in 2010 she discovered PTPN11 as the gene responsible for metachondromatosis by using whole-genome sequencing. She completed residencies in clinical genetics at both Universidade Federal de Sao Paulo and Johns Hopkins. Her main clinical and research focus is on identifying the genetic bases of rare phenotypes, mainly, phenotypes associated with cartilage tumors and vascular anomalies (including Ollier disease and Maffucci syndrome), and on understanding the physiopathology of these phenotypes to identify pharmacological strategies to treat them. She has worked extensively on developing strategies to better analyze the variants identified by next-generation sequencing and on novel strategies for data sharing. She participated on the development of PhenoDB, a phenotypic and genomic database, and created PhenoDB Variant Analysis Tool used worldwide. She is also one of the creators of GeneMatcher, VariantMatcher, and one of the co-founders of the Matchmaker Exchange, all intended to share next-generation sequencing data. She has also worked extensively on functional studies that evaluate the possible pathogenic effects of the candidate causative variants.

      When should I see a Retinopathy Pigmentary Mental Retardation doctor in Maryland, US?

      There are various reasons why you may want to see a specialist, such as: 

      • Your primary care provider recommends it. 
      • Your condition requires expert knowledge and specialized care. 
      • Your symptoms persist or worsen despite treatment. 
      • You need specialized testing or procedures. 
      • You want a second opinion.  

      What should I consider when choosing a Retinopathy Pigmentary Mental Retardation doctor in Maryland, US?

      It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

      How does MediFind rank Retinopathy Pigmentary Mental Retardation doctors in Maryland, US?

      MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

      What types of insurance are accepted by Retinopathy Pigmentary Mental Retardation doctors in Maryland, US?

      Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

      How can I book an appointment online with a Retinopathy Pigmentary Mental Retardation doctor in Maryland, US?

      MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Retinopathy Pigmentary Mental Retardation doctor search results page. 

      Why is it important to get a second opinion from a different Retinopathy Pigmentary Mental Retardation doctor?

      Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

      How can I prepare for my appointment with a Retinopathy Pigmentary Mental Retardation doctor in Maryland, US?

      Prepare for your appointment by gathering the following items: 

      • Copies of medical records (dating back at least one year) 
      • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
      • Family history of disease 
      • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
      • Allergies to medications, food, latex, insects, etc.  
      • List of questions and concerns 
      • Your insurance card 

      You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

      What questions should I ask my Retinopathy Pigmentary Mental Retardation doctor?

      Here are some sample questions: 

      • Can you explain in simple terms what this condition is and how it’s treated? 
      • What symptoms or side effects should I watch for? 
      • What tests will be involved, and when can I expect results? 
      • Are there other specialists I need to see? 
      • What’s the best way to reach you if I have follow-up questions? 

      How can I learn about the latest clinical trials and research advances my Retinopathy Pigmentary Mental Retardation doctor may know about?

      MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

      MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

      Can I filter my search to show male or female Retinopathy Pigmentary Mental Retardation doctors in Maryland, US?

      Look for the filter feature on the left side of the Retinopathy Pigmentary Mental Retardation doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

      Can I filter my search to find a Retinopathy Pigmentary Mental Retardation doctor that offers video calls?

      Look for the filter feature on the left-side of the Retinopathy Pigmentary Mental Retardation doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
