Eyes are the windows into the Brain

Here, I discuss 9 situations where symptoms are related to eyes or vision, but disease pertains to brain or nervous system.
1. Sudden onset painless loss of vision- Optic neuritis (inflammation of optic nerve)- Multiple sclerosis
#MedTwitter

2. Sudden onset loss of vision on one half (left or right)- called homonymous hemianopia- usually caused by an infarct (clot) of occipital lobe of brain.

3. Inability to see on outer aspects of visual field (temporal visual field loss)- usually caused by pituitary tumor.

4. Drooping of one or both eyelids- called ptosis, usually caused by myasthenia gravis or third cranial nerve palsy.

5. Double vision (diplopia)- caused by 3rd, 4th or 6th cranial nerve palsies; also myasthenia gravis.

Outdoor activity reduces the incidence of myopia in children
1. #Myopia is a refractive error of eyes, which causes near-sightedness (and impairment of far #vision). It is a lifelong disease and sufferers usually need glasses (or contact lenses) for life.
#MedTwitter #eyes

2. The incidence of myopia has been gradually increasing, possibly because children have been spending more time watching screens of computers and smartphones from very close (distance).

3. The incidence of myopia has further increased during COVID 19 pandemic, possibly because screen time further increased during the pandemic (for online classes as well as for recreation/leisure time activities).

1/ XBB.1.5 has a much stronger ability to infect people, binding stronger to ACE-2 receptors. We have these in our nose,& throat but also in our eyes & ears.

COVID as been known to infect through the eyes but its been fairly rare. XBB.1.5 will likely increase the odds.

2/ Pink eye symptoms will likely be a COVID infection for the next month or two, at least. There is a good chance it will be the XBB.1.5 variant. Searches for Conjunctivitis & Pinkeye are on the rise, as expected. Most people won't make the connection to COVID but now you know.

3/ An early study, "Our study found that the average duration of conjunctival congestion was 5.9 ± 4.5 days (mean [SD]), ranging from two to twenty-four days"
Initial top 3 symptoms:
Dry eye (20%)
Blurred vision (12.7%)
Foreign body sensation(11.8%)

#eyes becoming smaller in evenings could be a sign of #neurological illness

1. I was seeing the last patient, on what had been a busy Monday. While counselling the patient's attendant (aged 45), I noticed that her left eye was smaller than the right.

#MedTwitter #neurotwitter

2. On enquiry, she confirmed that her eyes were of equal size in mornings, but left eye became smaller as the day progressed. This was the case for the past 4-5 months. She had no other issues. This had been noted by her family members and friends too. An eye check up was normal.

3. I discussed with her that this could be a sign of #myasthenia gravis (MG) and asked for investigations. Repetitive nerve stimulation was normal. However, acetylcholine receptor antibody was high (8; normal value<0.25). The diagnosis of MG was confirmed. CT chest was normal.

As an aspiring #Artist , I love to Paint/Sketch my own perspective & observations of things that inspires me. I've been doing this for a decade & would love to share it on this platform.

Hence, I am starting this thread where I'll add my couple of #artwork everyday. Let's go...

"Under the same moon, Let's watch it together, tonight."

This tiny crab trapped in 100-million-year-old amber is the most complete fossil crab ever discovered! But how did a crab get trapped in amber in the first place? Here we tell you the story
science.org/doi/10.1126/sc… #Science #Evolution #SciComm 1/n

Transitions from marine to non-marine environments (e.g., land, brackish & freshwater) are an infrequent even in most animal groups. And yet, true crabs, or #Brachyura, have done it independently over a dozen times! #ocean #freshwater #evolution 2/n

Amber is like a time capsule that preserves organisms like frozen in time. While most fossils in amber are land-dwelling animals—principally insects—, aquatic organisms such as crabs are extremely rare! #amber #jurassicpark #Cretaceous #Crabs Photo by @LidaXing1982 3/n

FIRST AID FOR HOUSEHOLD POISONING 🧵

If a person is poisoned by bleach, fuel, acid, drugs, fumes, etc, the first aid treatment you give can prevent death!

What to do depends on type of poison & whether it's on the skin, eyes, inhaled or swallowed.

Share!
#FirstAidForPoisoning

What to do:

1. If poison is on the #skin or clothes;

- quickly & carefully remove victim's clothes
- pour large amounts of #water over the skin for 15 minutes
- wash skin thoroughly many times with soap & water
- move to nearest hospital!
#FirstAidForPoisoning

2. If poison is in the #eyes;

- remove any contact lenses
- pour CLEAN WATER in the eyes for 15 minutes (DON'T USE SOAP!)
- encourage blinking
- move to hospital instantly

Every second here matters & a slight delay could lead to permanent loss of sight!

There's a group on #Flickr whose title always gives me a laugh: "Narcissism in Color". When I make selfies, I have to admit that I am very much like Narcissus of mythology: the person who looks at them the most is me. This audience leans over the edge of the pool and dreams.

There's a strong association between #narcissism and dreams in #mythology. Many of us dream of that face in the pool, giving it fame that we think we deserve. The Instagrams of young people attract many likes. But this is no country for old men.

I received a very beautiful message this #Diwali and found it #TooGoodNotToShare ..
Most know that Diwali is a #FestivalofLights

#TheFiveLamps ..

While we all light our houses, do spend some time today to light a few lamps inside you and sit in silence with your eyes closed.

#Light the first lamp inside u and let it burn your #anger and or #jealousy that u may have for any one till date; see it melt away...

Light the second lamp and let it burn away unwanted #greed and desires... feel #happy and contented with what you have been blessed with.

#Light the third lamp and let it fade away all #insecurities that you may have in your mind related to anything or financials; just believe that #God has given u life and he will surely give you enough to survive.#
