This document discusses diplopia (double vision) from an orthoptic perspective. It defines diplopia and describes the requirements for binocular single vision. There are three main types of diplopia: physiological, pathological, and functional. Pathological diplopia can be binocular or monocular. The two most common mechanisms for diplopia are misalignment of the visual axes and abnormalities of the ocular media or refractive errors. A thorough history, examination, and testing are required to determine the type and cause of diplopia and guide treatment.

An Ophthalmologist’S Approach To Visual Processing Learning Differences Harol...Ricardo Guimaraes
American Academy of |Ophthalmology says there is no involvement of vision in dyslexia. Should ophthalmologists get involved with dyslexia? Is dyslexia an eye or vision problem?
In the past, most ophthalmologists read or
were told that treatment of the disorders
affecting children with dyslexia and other
learning disabilities fell outside the field of
ophthalmology because the brain, and not the
eyes, is the main organ active in the process
of thinking and learning
Double vision, or diplopia, is a relatively infrequent presenting symptom in the emergency setting, representing 0.1% of Emergency Department (ED) complaints (1). Diplopia can result from benign processes, such as dry eyes or idiopathic cranial nerve palsy, to emergent conditions with high morbidity, such as stroke, aneurysm, or inflammatory processes. Given a wide range of possible outcomes for a less common presenting complaint, it is worth reviewing the neuroanatomy and etiologies of diplopia, as well as a generalized approach to the patient presenting to the ED with double vision.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

2. Definition
Diplopia or double vision is the subjective
complaint of seeing two images of an object
instead of one.
3. What does the faculty of BSV
require?
Perfect ( or near perfect ) alignment of the
visual axes simultaneously on the object of
regard
Perfect ( or near perfect ) retinal
correspondence
Perfect central ( or paracentral ) fusional
capability.
Perfect ( or near perfect ) optics to allow
only one image to be formed on the retina
and the same single image to be formed
on the other
7. Mechanism of Diplopia
The two most common mechanisms for
diplopia are visual axis misalignment and
abnormalities of the ocular media or
refractive errors .
8. Binocular diplopia
In ocular misalignment, the image of an
object that is being viewed does not fall on
fovea of both retinas.
This causes binocular diplopia which
disappears on closing one eye
10. Monocular Diplopia
The abnormalities of the ocular media or
refractive errors lead to monocular diplopia
that persists in the affected eye even if the
other eye is closed.
11. Functional Diplopia
Diplopia without any pathological cause is
termed functional.
However, it is a diagnosis of exclusion and a
thorough examination and appropriate
investigations are mandatory to rule out a
pathological cause first.
12. Importance
It is important to differentiate monocular
from binocular diplopia.
The diagnosis of monocular diplopia usually
obviates the need for a detailed neurological
examination
13. Causes of Monocular Diplopia
Refractive error
Anomalies of the tear film
Corneal defect (e.g., irregular astigmatism)
Cataract
Media opacities
Retinal defects
14. Causes of Binocular Diplopia
The causes are multifactorial but results most
commonly from an acquired misalignment of
the visual axis secondary to recent onset of
extraocular muscle paralysis.
15. History
A detailed history. Points
1. When and how did the double vision started?
2. Whether diplopia disappears or persists after
closing one eye?
3. Associated symptoms with double vision if any?
4. Is it constant in all gazes or more in a particular
gaze?
5. Is it more for far or near fixation?
16. HISTORY
6.Whether the images are horizontally, vertically
or obliquely separated?
7. Is the diplopia constant, intermittent or variable?
8.Whether diplopia worsens at the end of the day?
9. History of any trauma to eye, face, head or any
history of ocular surgery recent or in past.
10. Detailed history of systemic diseases like
diabetes mellitus, hypertension, thyroid
disorders, myasthenia gravis should be taken.
17. Leading questions
In which direction of gaze are the images
maximally separated?
Diplopia is maximum ( separation of images)
in the field of action of the paralysed muscle.
To which eye does the “outer” image belong?
The false image ( the image belonging to the
eye with the hypofunctioning muscle ) is
always peripherally situated
18. Clinical Evaluation
For monocular diplopia
Pin hole test
Refraction
Anterior segment examination with slit lamp
Detail fundus examination for retinal
disorders
19. The evaluation of binocular
diplopia
1. Abnormal head posture
2. Orbital and lid abnormalities
3. Extraocular muscle movements
4. Pupillary reactions
5. Neuromuscular junction examination (M.G)
6. Examination of cranial nerves especially
third, fourth and sixth cranial nerves
20. The evaluation of binocular
diplopia
7. Prism Bar CoverTest
8. Maddox rod test
9. Double Maddox RodTest
10. Diplopia charting (R/G goggles)
11. Paretic vs restrictive etiology
12. HessTest
13.Worth four light test
21. Diplopia Charting
This test helps in recording the subjective
deviation by asking the patient to quantify
the separation between the double images,
dissociated by red green glasses.
Main points to be remembered are:
a. Maximum separation is in the quadrant in
which the muscle acts most (field of action)
b.The image that appears farthest, belongs to
the deviating eye
c.The image is displaced in direction of action
of paralysed muscle.
22.
23. Interpretation
i. If two images are joined together—no diplopia
ii. If images are separated—confirms diplopia.
iii. Maximum separation is in the quadrant in
which (the muscle moves
the eye) the muscle is restricted.
iv.The image is displaced towards the field of
action of the paralyzed muscle.
24. Interpretation
v. If horizontal separation with uncrossed
images—esodeviation.
vi. If horizontal separation with crossed
images—exodeviation.
vii. If vertical separation with uncrossed
images—oblique muscles involved.
viii. If vertical separation with crossed image—
vertical recti muscle involved
25. Systemic Investigations
1. Blood sugar levels / HbA1C for Diabetes
Mellitus
2.Test for myasthenia gravis –
electromyography (EMG), nerve conduction
studies with a repetitive stimulation test and
anti - acetylcholine receptor antibodies
3.T3,T4,TSH for thyroid eye disease
4. CT scan / MRI of brain and orbit for thyroid
eye disease, any intracranial or orbital
pathology.
26. Treatment
1. Treat the underlying cause, wherever possible.
2. Correction of refractive errors if present.
3. Unilateral eye occlusion therapy with either an
eye patch or by blurring one lens of the patient’s
glasses with semi-opaque surgical tape.
4. Prisms are used for optical correction of
symptomatic binocular diplopia.
5. Orthoptic exercise (CI)
6. Surgery for strabismus can be done to restore
ocular alignment after a period of observation
for at least 06 months.
