- Medical Weight LossWe follow you with repeat visual fields throughout the process. We intervene with medicines or surgery if your visual fields are tending to worsen. While it is a long process, we gradually decrease your visits from weekly to every 6 months. Diet and weight loss are difficult but extremely important. We will look for causes of the raised intracranial pressure. This will involve MRVs which look at the outflow system of the brain. Sometimes there are constrictions which may require angiography and stents. In rare cases there is a clot which will require anti-coagulation.
- Primary CareMany health insurance plans require referral authorization from your primary care physician prior to consultation with a specialist. In addition, most plans also require preauthorization before any type of surgical procedure or specialized treatment. It is your responsibility to obtain the required referral authorization from your primary care physician.
- GlaucomaDr. McHenry helped train the next generation of eye doctors, so you can rest assured that you are in experienced hands. He has over 10,000 patients who have optic neuropathies and over 1,500 with ptosis. His specialties include optic nerve disease, pseudo-glaucoma, pseudotumor cerebri, diplopia, nerve palsies, ptosis and lid retraction, tearing and thyroid eye disease, and visual loss of undetermined causes.
- OphthalmologyWhile we are a both a full service sub-specialty practice in Neuro-ophthalmology, Oculoplastics, Orbital Surgery and Strabismus practice, we are super-specialized in Optic Neuropathies, Thyroid Eye Disease and Adult Strabismus. Beyond that we are a quaternary care center in Neuro-ophthalmic Surgery, Pseudotumor Cerebri, Ocular Myasthenia and Giant Cell Arteritis.
- Eye ExamAfter reviewing your records and performing a history and eye examination, you will undergo visual field testing and we will look at your retina and optic nerve. This is called the posterior segment examination. It involves dilating your pupils and is an essential part of every neuro-ophthalmic examination. We dilate your pupils at every visit. If Dr. McHenry can’t see enough through an undilated pupil doing it a hundred times a day, no one can. The appearance of “the back of your eye” along with your visual field test will help us localize your problem. The optic nerve may appear swollen, pale, or normal. We will follow its appearance at each visit to decide which step to take along the pathway to improvement.
- Internal MedicineDr. McHenry then interned in Internal Medicine at Presbyterian-University of Pennsylvania and did his ophthalmology residency at Wayne State University in Detroit. He was Chief Resident there and went on to do a fellowship in Neuro-ophthalmology, Oculoplastics and Orbital Surgery under Thomas Spoor, MD at the Kresge Eye Institute.
- NeurologyNeuro-ophthalmologists are the medical detectives of neurology and ophthalmology. They see the cases that other doctors cannot figure out. Dr. McHenry is also an oculoplastic and orbital surgeon and has extensive experience in strabismus surgery and is a leader in Interventional Neuro-ophthalmology.
- ThyroidFinally, extra fat deposits around the eyes can be removed. This can return patients to their normal appearance. Most of these procedures can be performed in the office under local anesthesia. Excess skin can also be removed. As thyroid disease waxes and wanes these procedures can be repeated.
- UltrasoundIf you are new to Dr. McHenry, your insurance may require a referral from your doctor to see him. You may need a number of tests including blood work, CTs, MRIs, ultrasound, electrophysiology, topography, pachymetry, visual fields, fluorescein angiography, gonioscopy, optical coherence tomography, and ophthalmoscopy. Your initial visit may take several hours. There may also be additional studies to perform. There will be follow-up appointments.
- MRIIf your nerve is swollen, it is important to consider the appearance of your other eye. If that optic nerve is also swollen, then we become concerned that the pressure of the fluid surrounding your brain is too high. In the vast majority of patients this is due to being overweight, but we get an MRI to make sure nothing bad is going on. Then if you have visual loss, we must check the intracranial pressure. This is done by experts in anesthesia and neuroradiology who perform lumbar punctures for a living.
- ChemotherapyDr. McHenry will not give up until he has either improved your condition to its maximum, or if that is not possible, until he has stabilized you. He will consult with leading hematologists, radiation oncologists, oncologists, endocrinologists, pain management doctors, neurologists, neurosurgeons, otolaryngologists, cardiologists, radiologists, surgeons, and pulmonary doctors. Depending on your condition, he may treat you with immunosuppressive, anticoagulation, chemotherapy, radiation therapy, vitamins, supplements, diet, surgery, and medications.

- OtolaryngologyDr. McHenry grew up on a farm where he raised Black Angus steers, Suffolk sheep, and learned construction and landscaping. His father had degrees in both agriculture and chemistry and was trained in ophthalmology, otolaryngology and plastic surgery and practiced medicine. The elder Dr. McHenry worked on the farm until he was 94 and was a major Inspiration for Dr. McHenry. Another influence on Dr. McHenry was one of his father’s friends, Dr. Frank Walsh. Dr. Walsh is considered the founder of neuro-ophthalmology and wrote the definitive text on neuro-ophthalmology and helped young John to direct his career toward his chosen field.
