List Of Common Ophthalmic Abbreviations
This list is not inclusive of all medical abbreviations used by the physicians and medical personnel of the Spokane Eye Clinic, but the most commonly used acronyms have been referenced.
When you get an eye report for a student, are you sometimes confounded by all the abbreviations?
This tip sheet has been designed as a quick reference sheet for all those abbreviations, and hopefully will make it easier for you to read and understand eye reports that are a part of your students’ records.
Certain abbreviations are current within the profession of optometry. They are used to denote clinical conditions, examination techniques and findings, and various forms of treatment.
Most retinal surgeons are trained to create formal retinal drawings of the fundus.
Retinal drawings are useful to document pathology, although more and more people now prefer fundus photographs.
Can be used for serial follow up of patients to document changes in the pathology.

A 54-year-old man, Mr. Stephen Smith, was brought by ambulance to the Emergency Department. He had woken up from sleep with slurring of speech and weakness of his right arm and leg. His wife was extremely distressed as Mr Smith had been perfectly well the previous night when he went to sleep. Within 20 minutes after the initial call was made Mr. Smith was admitted to the Emergency Department and was reviewed by the SpR covering the Regional Specialist Stroke Unit. Mr. Smith had been on regular antihypertensive medication (lisinopril) for 8 years. He smoked 5-8 cigarettes a day and was a social drinker consuming about 6 units of alcohol a week. He was not diabetic.
His Serum lipids were checked and was advised to reduce weight and started on a Statin (Simvastatin). There was no family history of hyperlipidaemia but his grandfather died after a Stroke. Mr. Smith had an urgent appendectomy 1 week and made an uneventful recovery. He lives with his wife in a 4-bedroom detached house.
Neurological examination showed that Mr. Smith was fully conscious and alert. He had an upper motor neuron facial palsy on the right side. He had expressive dysphasia but appeared to comprehend speech. He was just able to lift his right arm off the bed for a short period but had no grip. His right leg was weak.
Reflexes on the right side were exaggerated and his right plantar was extensor. He responded to touch and pin prick equally on both sides. He either had visual inattention or a visual field defect on the right side. He had no papilloedema His blood pressure was 164/96, pulse 84 per min, regular. Other systems were entirely normal.
ECG and all routine blood tests were performed. An emergency CT scan was requested and even though the scan was normal the SpR ruled out emergency thrombolysis in this instance. Mr. Smith was admitted to the Acute Stroke Unit and was seen by the Stroke Consultant. Mr. Smith remained fully conscious and alert but had some difficulty in swallowing. Hence an intravenous infusion was commenced and an alternate strategy was adopted for providing his nutritional requirements. A carotid Doppler scan was requested.
After 3 weeks, Mr. Smith seemed to make good progress and the MDT meeting recorded a consistent improvement in his Barthel Index. The Stroke Team met him with his wife and discussed arrangements for discharge home. His wife was keen to know what support measures were available to them when Mr. Smith returned home. She also wanted to know about the risk of a future stroke and how this could be cut down.
ILOs:-
1- Consider the differential diagnosis of speech.
2- Discuss the risk factors for stroke and primary prevention of stroke.
3- Discuss the overall management of a patient with an acute stroke.
4- Complications of stroke

MANAGEMENT OF ATRIOVENTRICULAR CONDUCTION BLOCK.pdfJim Jacob Roy
Cardiac conduction defects can occur due to various causes.
Atrioventricular conduction blocks ( AV blocks ) are classified into 3 types.
This document describes the acute management of AV block.
These lecture slides, by Dr Sidra Arshad, offer a quick overview of physiological basis of a normal electrocardiogram.
Learning objectives:

2. Describe how dipoles generated by the heart produce the waveforms of the ECG
3. Describe the components of a normal electrocardiogram of a typical bipolar leads (limb II)
4. Differentiate between intervals and segments
5. Enlist some common indications for obtaining an ECG

ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
