2.Family problems, including disrupted spousal relationships (separation and divorce, impotence, and extramarital affairs).

3.Social problems, including isolation from peers, withdrawal from nonmedical activities, unreliable and unpredictable behaviors at work, and inappropriate behavior at social functions.

4.Work-related problems, including tardiness, absence without explanation, loss of interest in work, giving inappropriate orders

or responses to telephone calls regarding patient care, spending excessive time at the hospital, and demonstrating marked mood

Given all the adverse effects of residency stress addressed above, it may come as a surprise that there is no unanimity' a m o n g medical educators

and

trainees about the effect of stress. Some view stress as necessary

and

beneficial

and others see it as

harmful. M o s t would agree, howev-

er,

that stress

becomes pathologic

beyond a certain point.

Stress harms the doctor-patient relationship. Patients can be perceived as unwanted impositions during times of stress. The ability7 to empathize with patients is extremely important for delivery7 of health care with compassion. It can be argued that a stressed, sleep-deprived physician may be ill prepared to have or to show empathy, often finding the patient's complaints frivolous and minute in comparison to his or her own. Because of the sacrifices they make, trainees may become egocentric and feel that ''the world owes us something."

Recognizing the potential sources of stress and its deleterious effects is essential when devising effective coping strategies. There may be circumstances beyond the ability of the individual resident to resolve, for which the resident should consider seeking external help. Residents occasionally fall victim to the common misconception that a physician must have an answer for everything and must be able to cope independently with every problem. This misconception is exemplified bv the adage "Physician heal thyself," which may imply to some that asking for help is an admission of unworthiness and may deter residents and trained physicians from seeking help, admitting fault, and accepting guidance. Although many perceive this aura of infallibility to be essential for the doctor-patient relationship and even to have a therapeutic value to patients, it should be clearly recognized that, like many other medical traditions and mythologies, this perception has not been subjected to scientific scrutiny and could very well be false.

Ethical Considerations

Dealing With Early Discouragement

Discouragement early in residency is common. It stems largely from the psychologic impact of having to assimilate a novel body of knowledge dealing with unfamiliar regional anatomy and physiology and using special terminology,'equipment, instrumentation, and procedures. The typically variable knowledge base among residents at the beginning of the residency can discourage those who feel they are starting behind their peers. Discouragement can be compounded by any of the types of stress described earlier. Throughout the history of medical education, residents have found that such discouragement is self-limited. It generally resolves within a few months as its sources are addressed and overcome.

The most effective method of dealing with early discouragement is a mature, methodical, long-term approach to the process of learning. Comparing and sharing experiences and feelings with colleagues at various levels of experience and training is helpful. The fact remains that the task of mastering ophthalmology can appear daunting to the beginning resident. There are no good substitutes for hard work combined with effective time management.

Ethical Considerations

. ,,

 

Ethics are reflections of our moral values. Your ethical standing is a

 

 

 

 

reflection of your actions and attitudes. The ethical practice of oph-

 

";

,

'

thalmology must at all times be borne in mind by the physician-in-

 

 

 

 

training. It safeguards the healthy foundations of the physician-patient

 

 

 

 

relationship. The principles involved, formalized in the Code of Ethics

 

 

 

 

of the American Academy of Ophthalmology, are designed to ensure

 

 

 

 

that the best interest of die patient is paramount. These principles can

 

 

 

 

be summarized as follows:

 

 

 

 

1. Provide care with compassion, honesty, integrity, and respect for

1

 

 

 

human dignity.

 

 

 

 

2. Do not refer to a patient as the retinal detachment. Instead, always

 

 

 

 

refer to patients by their names.

 

 

 

 

3. Seek a healthy personal lifestyle. An ill, problem-ridden physician

~ff.

 

 

 

is less likely to genuinely empathize with the minor ailments of

f

 

 

 

patients.

38Chapter 1: Introduction to the Practice ot Ophthalmology

4.Understand the psychology of illness. Patients or family members may appear frightened, angry, or hostile. Learn to recognize and to deal effectively with these emotions without ever becoming defensive or hostile yourself.

5.Maintain clinical and moral competence to avoid doing harm (Hippocrates: primum non nocere) and to ensure provision of excellent care. Clinical competence is accomplished by continued study and by appropriate consultation. Moral competence calls upon the physician to practice moral discernment (understand and resolve the ethical implications of clinical encounters), moral agency (act faithfully and respectfully on behalf of the patient), and caring in the physician-patient relationship. Know your limits.

6.Communicate openly and honestly with patients. Never misrepre-

sent your status. Introduce yourself by name and identify yourseli as a resident. Provide complete and accurate information about '. treatment options.

7.Safeguard the patients right to privacy within the constraints of the law.

8.Do not allow fees for ophthalmologic services to exploit patients or third-party payers.

9.Always strive to preserve, to protect, and to advance the best interests of the patient. Reflect this in your own actions and attitude by placing your patient's welfare ahead of your personal ambitions and desires.

10.Take thoughtful measures to effect corrective action if colleagues deviate from professionally or ethically accepted standards.

About This Manual

The purpose of this manual is to facilitate your transition from intern to first-year ophthalmology resident. Few beginning residents have the necessary training to function effectively as an ophthalmic clinician, yet most are generally expected to hit the ground running. This manual covers the basic clinical knowledge and essential examination techniques needed to make this task possible. It provides an overview of the subject matter you are about to assimilate, with emphasis on practical clinical knowledge. It should be read within the first feu weeks of residency and then consulted during the following leu months in conjunction with other educational materials. The manual can also serve as a practical guide to medical students and house officers rotating through ophthalmology.

 

Beyond This Manual: Lifelong Education

9.

 

This manual is intended as a practical introduction for the begin-

 

ner. It is neither a diagnostic manual nor a treatment guide. You should

y

consult additional sources to amplify certain information as the need

 

arises during the first few months of the residency. Freely and fre-

 

quently consult a variety of ophthalmology textbooks, relevant journal

 

articles, more senior residents, technicians, and other physicians about

specific issues as they arise.

The sequence of chapters in this manual reflects the orderly progression of a thorough ophthalmologic evaluation. Most chapters include step-by-step instructions for performing many basic procedures and an appendix covers the topic of common eye medications.

Beyond This Manual: Lifelong Education

 

The physician-in-training must strive to achieve a balance between

 

education and training. Training connotes learning to perform specif-

 

ic tasks, such as examination steps and surgical procedures. The mean-

 

ing of education is much broader, entailing the thoughtful integration

 

of new knowledge into one's own personal experiences, insights, and

 

actions. Residency training must be supplemented by individually driven

 

education. It can be argued that the single most important iactor that

 

determines an excellent residency training outcome is the individual's

 

Own input into the education and training. A well-balanced education

 

can be obtained by diversifying sources of learning to encompass a

 

thoughtful mixture of reading books and journals, attending lectures

 

and conferences, and participating in informal discussions. One time-

 

honored approach to continuing education is to read about the disor-

 

ders you find in your own patients as you encounter them.

 

All residents should strive to obtain certification by the American

 

Board of Ophthalmology. Such certification is based on continuing

 

education, licensure, verification of credentials by the chairperson of

 

the residency program, the Written Qualifying Examination, and the

 

Oral Examination. Since 1992, the American Board of Ophthalmology

 

has required recertification every 10 years.

 

Active pursuit of education and training must continue beyond res-

 

idency. The beginning resident must make a commitment to sharpen

 

medical skills and knowledge through continual study, instruction, and

 

experience. Maintaining competence is essential to the ethical practice

 

of ophthalmology and to the promotion of intellectual and professional

 

growth. Keeping up with medical and surgical discoveries and inven-

 

tions, which seem to change the practice of medicine almost daily, is nec-

.

essary to remain competitive in a marketplace that demands excellent

 

outcomes.

Chapter 1: Introduction to the Practice or Ophthalmology

The challenge of becoming an excellent ophthalmologist will be affected by the demands of health care reform. Increasing constraints on the time and economic resources available for education are further strained by the need to remain current and fully competent in an everevolving field. The American Academy of Ophthalmology offers the program Lifelong Education for the Ophthalmologist (LEO), a framework of Academy resources that can help members accomplish their continuing educational goals in the face of new challenges and imperatives. LEO recognizes the importance not only of clinical ophthalmic knowledge, but of aspects of health care delivery, practice management, and communications. It emphasizes the use of the best educational materials and technology to help members learn, self-assessment to detect areas of weakness, and self-customized study in those areas. Among other resources, LEO includes subspecialty topic summaries and special courses at Annual Meetings of the Academy.

Other sources of continuing education available to the ophthalmologist include the various American Academy of Ophthalmology publications (Figure 1.1). These include the 12-volume Basic and Clinical Science Course (BCSC), which is an excellent, condensed overview of le central themes in ophthalmology both for resident education and lifelong learning. Other Academy publications include Focal Points: Clinical Modules for Ophthalmologists; Ophthalmology Monographs; and clinical education videotapes. ProVision: Preferred Responses in Ophthalmology™, published by the Academy, is a multiple-choice question series that can be used as a self-assessment tool. ProVision Interactive:

elsewhere.

 

 

 

Another source for vital clinical information is the series of

 

Preferred

Practice Patterns (PPPs) published by the Academy.

 

Developed bv expert panels of the Academy's Preferred Practice

 

Patterns Committee, PPPs identify characteristics and components of

 

quality eve care. These guidelines are based on the best available sci-

 

entific data and provide guidance for the pattern of practice, although

 

not for the care of a particular individual. The guidelines presented in

 

PPPs are neither minimal nor aspirational but reflect the quality of eye

 

care commensurate with current knowledge and resources.

 

 

Numerous other excellent publications are available. These encom-

 

pass certain classic books (eg, Duane's series in ophthalmology), gen-

 

eral and subspecialty journals, and audiovisual and digital electronic

 

educational

material.

 

Pitfalls and Pointers

# - > • • : • : : ' - :

Avoid cutting corners or taking shortcuts in your practice as a new resident. Learn it right the first time.

Do not compromise patient care for the sake of training or any other personal benefit. Always consult a more knowledgeable or experienced physician if you are uncertain about how to proceed in a clinical situation.

Do not be embarrassed to use this (or any) introductory manual. Adopt a lifelong approach to learning.

Do not hide your own limitations in skill and knowledge as you begin your residency. Strive to improve upon them and be receptive to criticism.

Remember that there is more to professional success than learning the medical facts and the surgical techniques. The art of practicing medicine is best achieved by a well-rounded, mature, and compassionate physician who also knows the medical facts well.

Do not publicly denounce or belittle the care given by previous practitioners by saying, "Your doctor did not know what he or she was doing," or "That was malpractice." Avail yourself of the facts before passing any judgements, but remember that you are a medical resident, not a judge.

Overview of the Ophthalmic Evaluation

I he purpose of the ophthalmic evaluation is to document objective and subjective measurements of visual function and ocular health. The specific objectives of the comprehensive ophthalmic evaluation are to

Obtain an ocular and systemic history7

Determine the optical and health status of the eye, visual system, and related structures

• Identify risk factors for ocular and systemic disease

P v

Detect and diagnose ocular abnormalities and disease

Establish and document the presence or absence of ocular

signs or symptoms of systemic disease

 

Discuss the nature of the findings and the implications with

 

 

the patient

-r?-.

Initiate an appropriate response (eg, further diagnostic tests,

 

 

treatment, or referral when indicated)

': M Chapter 2: Overview of the Ophthalmic Evaluation

The physician accomplishes these objectives by assessing the patient's

history and performing the necessary examinations, using specific

equipment as needed. A successful evaluation relies in pari also on the

physician approaching the patient appropriately and with a certain pro-

i

fessional demeanor, and is supported by the keeping of adequate

records. This chapter briefly discusses these important aspects of oph-

thalmic practice.

Obtaining a thorough history from the patient is the important first step in an ophthalmic evaluation (see Chapter 3). In general, the history includes the following information:

Demographic data, including name, date of birth, sex, nice, and occupation

The identity of other pertinent health care providers utilized bv the patient

Chief complaint and history of present illness

Present status of vision, including the patient's perception of his

 

or her own visual status, visual needs, and any ocular symptoms

Past ocular history, including prior eye diseases, injuries, diagnoses, treatments, surgeries, and ocular medications

Past systemic history, including allergies, adverse reactions to medications, medication use, and pertinent medical problems and hospitalizations

Family history, including poor vision (and cause, if known), and other pertinent familial ocular and systemic diseases

related structures. Components of the evaluation and chapters in this book in which they are discussed are listed below:

Visual acuity examination; visual acuity is determined with and without the present correction (if any) at distance and at near (see Chapter 4)

Determination of best-corrected visual acuity utilizing retinoscopy and refraction (see Chapter 5)

Ocular alignment and motility examination (see Chapter 6)

Pupillary examination (see Chapter 7)

Visual field examination (see Chapter 8)

• Examination of the external eye and ocular adnexa (see Chapter 9)

Examination of the anterior segment (see Chapters 10 and 11)

Tonometry to determine intraocular pressure (see Chapter 12)

Posterior segment examination (see Chapter 13)

Ophthalmic Equipment

The ophthalmic examination room and its equipment are sometimes referred to as a lane. Although the equipment in examining rooms varies widely, the components typically include the following:

Snellen acuity chart. This printed wall-hung chart, projected chart, or video display is used in determining visual acuity and in refraction (see Chapter 4).

Near visual acuity chart. This printed handheld chart is used to determine near visual acuity and as an aid in refraction (see Chapter 4).

Slit-lamp biomicroscope. This optical instrument is primarily used to perform anterior segment examinations. When combined

with an auxiliary lens, such as a Hruby lens, a +90 diopter or +78 diopter lens, or a Goldmann three-mirror lens, it is used to examine the posterior segment. It is also used in conjunction with a

gonioscopy lens to examine the anterior chamber angle (see

 

Chapters 10, 11, and 13).
