Different Types of Pink Eye













Pink eye or conjunctivitis is inflammation of the eyes clean membrane or conjunctiva. Causing redness, itching, swelling and discharge.

Symptoms include pink or red color in the whites of the eye, itching or burning or grittiness, the feeling of something in the eye. Watery or thick discharge from the eye. Swollen eyelids. Light sensitivity and crustiness on the lashes.

There are different types of pink eye. 

  • Viral pink eye-is an infection of the eye caused by a virus and is the most common cause of infectious conjunctivitis. Viral conjunctivitis can spread when you come in close contact with someone who has a viral eye infection, and then you touch your face or eyes. You can also get it from someone who is coughing or sneezing with a cold.
  • Bacterial pink eye- The bacterial form of conjunctivitis is very contagious and caused by many types of bacteria, including staph and strep. The bacterial type has rapid onset and progression.
  • Allergic pink eye- is a type of pink eye that occurs when allergy-causing foreign substances (allergens) cause inflammation in your conjunctiva.
  • Chemical/Irritant pink eye- or toxic pink eye happens when substances like smoke, dust, chemicals (chlorine, makeup), or even contact lens issues inflame the eye's clear lining, causing redness, watering, and a gritty feeling, but unlike infectious pink eye, it's not contagious and usually resolves after removing the irritant, often with flushing and rest. Common culprits include smoke, fumes, pool chlorine, cosmetics, and contact lens overuse. 

While most cases clear up with home care like compresses and hygiene. Some need doctor’s prescribed treatments like antibiotic or antiviral medication.

Is Hibiscus Tea Good for Eyesight

 












Hibiscus tea is a tart, caffeine-free, cranberry-like infusion made from the dried magenta calyces, the fleshy, edible parts of the roselle flower. The tea can be served hot or cold. Packed with beneficial compounds like anthocyanins and polyphenols, they offer anti-inflammatory effects and protect against cell damage. Anthocyanins responsible for the colors, red, purple, and blue, are in fruits and vegetables. Polyphenols are a class of compounds found in many plant foods that includes flavonoids, phenolic acids, lignans, and stilbenes. There are more than 8,000 different types of polyphenols that have been identified so far.

Hibiscus tea can be beneficial for eyesight, as it contains antioxidants and vitamin C, which help to strengthen the blood vessels of the eye, reduce oxidative stress, support retinal health, and potentially aid in managing high blood pressure.

Hibiscus tea is generally safe when consumed in moderation, though some side effects are possible. One study found that hibiscus and other hot teas may negatively affect the quality and water content of the ocular tear film. While research supports several health benefits of hibiscus, larger studies are still needed. Consult your doctor before using hibiscus supplements, especially if you take prescription medications.

Is There Any Value to Apple Vision Pro to People Who Are Visually Impaired







The launch of Apple Vision Pro (AVP) is an important step in the intersection of technology and healthcare, offering unique capabilities in mixed reality, which Apple terms “special computing “.

AVP stands out over other devices, such as meta quest pro and Microsoft’s halo lens, for advanced integration within healthcare workflows. The AVP‘s unique combination of high resolution, displays, precise, I, tracking, and seamless user interface offer distinct advantages in a clinical setting by enhancing, patient care, medical training, and immersive visualization experiences.

*Does insurance cover in the case of visually impaired? No, the Apple Vision Pro is not currently covered by medical insurance for the visually impaired because it is not classified or approved by the FDA as a medical device. It is sold as a general consumer electronics device. 

*How much does it cost?  $3499

*Does the newest AVP improve on the original? Apple Vision Pro headset, the newest model with the M5 chip notably improves on the original M2 version in performance, motion clarity, and comfort.

*What are the differences between VR and AR:

AR adds to the real world; VR replaces it. 

Hardware: AR uses smartphones/glasses; VR needs immersive headsets. 

Interaction: AR interacts digital with physical; VR interacts within the virtual space. 

• Both have many uses in healthcare.

AVP integrates VR and AR into a cohesive mixed reality platform to create a versatile platform that combines both functionalities.

There is room for improvement some visually impaired testers have compared it to wearing someone else’s glasses while other testers have said it is life altering technology for them. In some cases, it may depend on a person’s visual condition the AVP can be fitted with a custom lens insert. When you order your AVP at an Apple Store the strap is fitted for you. Some of the settings may need to be adjusted for eye tracking needs.

Use Them or Lose Them Vision Benefits – The Clock is Ticking

 













Vision benefits and Flexible Spending Account (FSA) funds follow a “use them or lose them” policy—they expire at the end of the year and do not roll over.

What you should do before the end of the year:

• Book a comprehensive eye exam for yourself and family members, as the exam is partially, if not fully, covered by vision insurance.

• Get new glasses, prescription sunglasses, or contacts to use your remaining allowance.

• Check to see if there is also an allowance for upgrades, such as anti-glare or blue light filters.

• Use any FSA funds to help pay for Eligible expenses.

• Schedule appointments as early as possible since the end of the year is a busy time for vision care, because of these benefits being close to expiration.

• Some vision plans cover specialty eyecare services, including treatment for dry eye, computer vision syndrome, and eye conditions like glaucoma.

On average, families across the United States lose $441 each year in unused benefits and FSA funds that they paid for. Do not let these benefits go to waste-use them before they expire on December 31st.

Remember the clock is ticking. Call now to schedule.

UPMC Vision Institute Using Ocular Genetics


UPMC Vision Institute uses the medical and research knowledge of UPMC and the University of Pittsburgh Department of Ophthalmology.

The ocular genetics team, including genetic counselors, are very important for patients with inherited vision problems, such as retinal dystrophy, front-of-the-eye disorders, developmental disorders, cornea problems, uncontrolled eye movements, optic nerve damage, and albinism, among many other conditions.

The most common disorders which UPMC specialists are skilled at treating include:

·       Retinitis pigmentosa is a group of inherited disorders that progressively reduce the retina’s ability to respond to light, leading to a loss of vision.

·       Stargardt disease is the leading inherited juvenile macular degeneration, characterized by progressive vision loss due to the degeneration of cells in the central retina.

·       Leber congenital amaurosis (LCA) is an inherited retinal degenerative disease that causes severely reduced vision from birth. This condition is characterized by early-onset visual impairment

·       Retinoschisis is a genetic eye disorder in which the retina splits into separate layers. This separation impairs both central and peripheral vision, potentially affecting activities such as reading, recognizing faces, and navigating spaces. Early diagnosis and management are important to help preserve vision and quality of life.

·       Optic neuropathy refers to damage to the optic nerve, which may result in vision loss. Common symptoms include blurry vision, blind spots, and reduced color perception. While genetic factors are a frequent cause. Early diagnosis and intervention are crucial to help preserve vision and improve quality of life.

·       Pediatric cataracts are clouding of the eye's lens in children, which can be present at birth (congenital) or develop later (acquired) due to causes like genetics, infection, trauma, or certain medical conditions.

Genetic counselors collaborate closely with optometrists, ophthalmologists, and other specialists to assess patients’ medical and family histories. They also coordinate genetic testing and provide expert interpretation of results, helping patients and families understand their inherited vision conditions and make informed decisions about care.

Ultramodern care, diagnostic evaluation, testing, genetic counseling, advanced genetic testing, and access to modern treatments. Some of those initiatives include repairing genetic defects in the eye using gene therapies, using stem cells to repair severely damaged corneas, cortical vision, or sending images directly to the brain from a camera, implantation of a bionic chip new treatments for macular degeneration and glaucoma, and regenerating the optic nerve.

Crusty eyelids in the A.M., why it happens


 









Sleep crust, also known as eye gunk or by its technical term, rheum, is a common occurrence. Rheum is a harmless mixture of exfoliated skin cells, oils, and tears produced or shed that accumulate in the eyes. We all get that crusty stuff in the corners of our eyes when we wake up in the morning.  It is all part of a good night's sleep.

This buildup happens because, during sleep, you do not blink, allowing secretions and debris to collect and dry in the corners of your eyes and along the eyelash line.

This residue is a result of the eye’s normal protective processes. Blinking throughout the day helps flush away mucus and other debris from the surface of the eye.

Therefore, finding crusty residue in the corners and along the lash line of your eyes is normal, unless it is accompanied by symptoms such as redness, pain, or excessive discharge, which may indicate an underlying condition. It should be white or light cream color—which is normal. 

If the discharge is yellow or green, that can be a sign of bacterial conjunctivitis—a common form of pink eye. There are also chronic conditions, like blepharitis (a type of inflammation), dry eye, and allergic conjunctivitis that can cause sleep crust. In some cases, it could be enough to make your eyes stick together. In those cases, see an eye care professional.
