Janet Sunness, MD in Baltimore: Retinal Specialist for Vision-Threatening Eye Disease
Janet Sunness, MD is a retinal specialist in Baltimore who focuses on age-related macular degeneration, diabetic retinopathy, and inherited retinal conditions, treating patients who need medical or laser intervention beyond what a general ophthalmologist can provide.
What Janet Sunness, MD actually is
Sunness is a retinal ophthalmologist, a subspecialist who handles diseases affecting the retina—the light-sensitive tissue at the back of the eye. This differs from a general ophthalmologist, who performs routine exams, prescribes glasses, and manages common conditions like dry eye and cataracts. Retinal specialists in Baltimore are concentrated in academic medical centers and established private practices; Sunness has been recognized in peer-reviewed literature for research on low-vision rehabilitation and the natural history of age-related macular degeneration (AMD), which makes her a named authority rather than one of many interchangeable providers.
Services and what to expect
Retinal specialists typically handle wet and dry macular degeneration, diabetic eye disease, retinal detachment, macular holes, and inherited retinal dystrophies. Treatment options range from observation and optical aids for dry AMD to anti-vascular endothelial growth factor (anti-VEGF) injections for wet AMD—drugs like bevacizumab, ranibizumab, and aflibercept administered directly into the eye every 4 to 8 weeks. Pricing for injections and related imaging (optical coherence tomography, or OCT) is usually bundled under insurance; out-of-pocket cost depends entirely on your plan's deductible and coinsurance. A baseline comprehensive retinal evaluation typically runs $200 to $400 out-of-pocket for uninsured patients, though this varies by location and extent of testing.
Sunness is also known for low-vision rehabilitation counseling—advising patients with significant vision loss on magnification aids, lighting, and adaptive strategies—a service many retinal practices do not routinely offer in-office and that can improve quality of life materially when done early.
How this compares to other Baltimore retinal specialists
Baltimore has retinal specialists at Johns Hopkins Wilmer Ophthalmological Institute, University of Maryland Medical Center, Sinai Hospital (UM Medical Associates), and in private practices. Wilmer and UMB are high-volume academic centers with same-day or next-day urgent slots for retinal emergencies like detachment; they attract complex referrals and offer clinical trial enrollment for experimental treatments. Private retinal practices typically have longer appointment lead times (1 to 3 weeks) but may offer more continuity with a single provider. Sunness's published track record in AMD research and low-vision rehabilitation makes her valuable if your condition is complex or your vision has already declined significantly and you want structured guidance on living with it.
Who this suits and who it does not
Choose Sunness if your primary-care eye doctor has referred you for retinal disease management, if you have AMD or diabetic retinopathy, or if you have low vision and want formal rehabilitation planning beyond what an optometrist or general ophthalmologist offers. Do not expect her to handle routine glasses prescription updates, cataracts, or dry eye management; those belong with your general eye doctor. If you need retinal emergency care (sudden vision loss, flashing lights, new floaters, or a shadow in your visual field suggesting detachment), call an urgent care or ER ophthalmology service rather than scheduling an appointment—academic centers like Wilmer often field emergency calls 24/7.
What the first visit involves
A first retinal appointment includes detailed history (diabetes history, family history of eye disease, medications), dilated eye exam with a indirect lens to view the full retina, OCT imaging to measure retinal thickness and fluid, fundus photography, and visual field testing if indicated. Budget 90 minutes. Bring your insurance card, a photo ID, a list of current medications, and contact information for your primary eye doctor so records can be shared. If you are being evaluated for wet AMD or diabetic macular edema, you may be offered treatment the same day; if you are being evaluated for dry AMD or an inherited condition, the specialist will outline a monitoring plan and may order additional genetic testing.
Hours, parking, and logistics
Confirm Sunness's current location, office hours, and whether same-day dilated exams are available by calling ahead. Parking depends on whether the practice operates from a hospital, medical office building, or standalone suite; hospital-affiliated practices often have on-site or validated parking, while private offices may rely on street or lot parking. Insurance acceptance varies; contact the office to confirm your plan is in-network.
Janet Sunness is a named expert in retinal disease and low-vision care, not a generalist, and that specificity makes her a strategic choice for Baltimore patients whose eye disease has moved beyond routine management.
