What is "Emergencies in Neuro-Ophthalmology: A Case-Based Approach, 2nd Edition"?
Emergencies in Neuro-Ophthalmology: A Case-Based Approach, 2nd Edition, is a concise clinical reference for ophthalmologists and other healthcare professionals managing potentially vision- or life-threatening neuro-ophthalmic emergencies. Its case-based format focuses on clinical examination, localization, diagnostic imaging, triage, and practical management decisions.
Introduction
Neuro-ophthalmic emergencies can present with deceptively familiar symptoms: a red eye, ptosis, diplopia, anisocoria, visual-field loss, optic disc swelling, or sudden visual impairment. The challenge is recognizing when an apparently ophthalmic complaint may actually signal a neurological, vascular, orbital, or intracranial emergency.
Emergencies in Neuro-Ophthalmology: A Case-Based Approach, 2nd Edition, addresses this clinical challenge through a deliberately practical format. Rather than attempting to provide an exhaustive textbook of neuro-ophthalmology, the book is designed as a concise guide for clinicians confronted with potentially vision- or life-threatening presentations. The preface specifically describes its purpose as helping comprehensive ophthalmologists make emergency triage decisions during initial evaluation and treatment.
The book is particularly relevant to ophthalmology, neuro-ophthalmology, neurology, emergency medicine, and related clinical practice. Its intended setting is the emergency room or ophthalmic clinic, where rapid interpretation of clinical findings and appropriate imaging or referral may be critical.
What makes the book distinctive is its case-based teaching structure. Each case presents a focused clinical history, examination findings, illustrative figures, and expert discussion of the diagnostic and management considerations.
The cases are based on real clinical experiences, although the clinical details have been modified for teaching and presented as composite histories.
Book Overview
The authors bring backgrounds in ophthalmology and neuro-ophthalmology. Andrew G. Lee is described as a professor and neuro-ophthalmology specialist with multiple academic appointments.
Saif Aldeen Alryalat has dual fellowship training in glaucoma and neuro-ophthalmology and has published extensively. Osama Al Deyabat is identified as a neuro-ophthalmology fellow, while Noor Laylani is an attending ophthalmologist who completed neuro-ophthalmology fellowship training.
The preface explains that the text incorporates perspectives from ophthalmology-based and neurology-based neuro-ophthalmology.
This is important because many neuro-ophthalmic emergencies require clinicians to move beyond the eye examination and consider neurological localization, vascular disease, intracranial pathology, and systemic conditions.
What This Book Covers
The central focus of Emergencies in Neuro-Ophthalmology, 2nd Edition, is the recognition and initial management of acute or potentially serious neuro-ophthalmic presentations.
The 18 chapters are organized around clinical problems rather than broad disease categories. This makes the book particularly useful when the clinician begins with a symptom or examination finding rather than a confirmed diagnosis.
Major clinical areas include:
Ptosis, ophthalmoplegia, and red eye
The opening chapters examine acute painful and chronic painless combinations of ptosis, ophthalmoplegia, and ocular redness. The cases illustrate how apparently ocular symptoms can indicate disorders involving the cavernous sinus and carotid circulation.
One case, for example, discusses carotid-cavernous fistula and emphasizes the importance of findings such as proptosis, ophthalmoplegia, elevated intraocular pressure, and abnormal conjunctival or episcleral vessels.
Homonymous visual-field defects
The book devotes multiple cases to homonymous hemianopsia, including painless acute presentations, painful presentations, and a febrile patient. The discussions use visual-field findings as a tool for neurological localization and explain why acute visual-field loss can require urgent neuroimaging.
Optic disc edema and papilledema
Two chapters address acute and subacute bilateral optic disc edema. The clinical discussions distinguish optic disc swelling associated with increased intracranial pressure from other causes and examine conditions such as idiopathic intracranial hypertension, cerebral venous sinus thrombosis, hydrocephalus, mass lesions, meningitis, vascular disorders, and medication-associated secondary intracranial hypertension.
The book also discusses the diagnostic role of MRI, MR venography, CT, lumbar puncture, cerebrospinal fluid analysis, and assessment of visual function in appropriate clinical contexts.
Cranial nerve disorders
The contents include acute isolated sixth nerve palsy and both pupil-sparing and pupil-involved third nerve palsy. These chapters emphasize clinical examination, localization, vascular risk factors, progression, and circumstances in which neuroimaging becomes important.
Acute optic neuropathy
An entire chapter is dedicated to acute unilateral optic neuropathy. The discussion includes clinical evaluation, neuroimaging, atypical presentations, and the relationship between optic neuritis and demyelinating disease.
Proptosis and thyroid eye disease
The chapter on acute proptosis with red eyes addresses thyroid eye disease and vision-threatening dysthyroid optic neuropathy. The discussion considers clinical diagnosis, orbital imaging, disease activity and severity, medical therapy, and orbital decompression when vision is threatened.
Anisocoria and Horner syndrome
The book includes separate discussions of acute anisocoria and acute anisocoria associated with neck pain. These cases demonstrate the importance of examining the pupil together with eyelid position and ocular motility. The neck-pain presentation highlights the need to consider internal carotid artery dissection in acute, painful Horner syndrome.
Other high-stakes presentations
Additional chapters address:
- Acute bilateral ophthalmoplegia with mental-status change
- Acute visual loss in a patient with leukemia
- Acute ophthalmoplegia after vomiting
- Optic disc edema with a macular star
- Acute transient monocular visual loss
- Jaw pain and headache in an elderly woman
- Acute bitemporal hemianopsia
- Acute painful ophthalmoplegia
Together, these cases cover a broad range of clinical situations in which visual or ocular-motor symptoms may be the first clue to serious neurological or systemic disease.
Key Features
The strongest educational features of the book include:
- Case-based organization built around realistic clinical presentations.
- Concise clinical histories that focus attention on diagnostically important information.
- Neuro-ophthalmic examination findings presented alongside the cases.
- Demonstrative figures supporting the clinical discussions.
- Expert management discussions associated with the individual cases.
- Emphasis on emergency triage and decision-making.
- Practical approach to diagnostic imaging and localization.
- Coverage of potentially vision- or life-threatening conditions.
- Practice Essentials sections that distill important clinical points.
- A relatively quick-read format rather than an encyclopedic treatment of neuro-ophthalmology.
Who Should Read This Book?
Medical Students
Medical students interested in ophthalmology, neurology, or emergency medicine can use the cases to understand how visual symptoms may localize lesions beyond the eye. The case format also provides a useful introduction to the clinical reasoning involved in neuro-ophthalmology.
Residents
The book is especially relevant to ophthalmology residents and residents encountering patients with acute visual symptoms. Its emphasis on examination, localization, imaging, and triage can help bridge the gap between theoretical knowledge and clinical decision-making.
Specialists
Ophthalmologists, neurologists, neuro-ophthalmologists, and clinicians managing emergency presentations may find the book useful as a focused clinical reference. Its stated purpose is not to replace comprehensive neuro-ophthalmology texts but to provide quick guidance in high-stakes situations.
Exam Candidates
The case-based structure can support revision of clinical localization and recognition of important presentations. However, the book does not describe itself as a dedicated board-review text, so it should not be treated as a substitute for an examination-specific review resource.
Why This Book Is Useful
Clinical relevance
The greatest strength of the book is its focus on situations where the clinician must decide what matters now.
For example, acute homonymous hemianopia can represent a retrochiasmal lesion, and the book's cases demonstrate how visual-field examination can guide localization and trigger urgent neurological evaluation. Similarly, acute bitemporal hemianopia can indicate a chiasmal emergency requiring prompt imaging.
Practical diagnostic reasoning
The cases repeatedly demonstrate a progression from symptom → examination → localization → imaging → management.
This approach is valuable because neuro-ophthalmology frequently depends on recognizing patterns rather than interpreting an isolated test result.
Imaging awareness
Imaging is an important recurring theme. Depending on the clinical problem, the discussions consider CT, MRI, diffusion-weighted imaging, MR angiography, MR venography, CT angiography, and other investigations.
High-stakes decision-making
The book is specifically designed around potentially vision- or life-threatening emergencies. Its discussions therefore emphasize situations in which delay, incorrect localization, or failure to investigate an atypical presentation could have significant consequences.
Learning efficiency
For busy clinicians, the concise case format is an advantage. The authors explicitly describe the book as a quick reference rather than an all-inclusive neuro-ophthalmology textbook.

Strengths of the Book
1. Strong case-based teaching model
Rather than beginning with lengthy theoretical discussions, the book places the reader directly into clinical scenarios. This encourages pattern recognition and diagnostic reasoning.
2. Focus on emergency presentations
The selected problems are not simply common ophthalmic complaints. Many represent clinical presentations in which neurological or vascular disease must be considered.
3. Concise and clinically oriented
The authors explicitly state that the text is intended to be concise, easy to read, and practical. That makes it particularly suited to clinicians who need a focused reference rather than an extensive theoretical textbook.
4. Integration of examination and imaging
The cases connect clinical findings with neuroimaging and other diagnostic investigations. This is particularly valuable in neuro-ophthalmology, where anatomical localization frequently determines the appropriate next investigation.
5. Expert clinical perspective
The case discussions provide expert opinions from neuro-ophthalmology perspectives rooted in both ophthalmology and neurology.
Limitations
The book's principal limitations are actually acknowledged by its authors.
It is not intended to be all-inclusive or comprehensive. Readers seeking detailed anatomy, pharmacology, physiology, or basic mechanisms of disease are directed toward longer neuro-ophthalmic texts.
The management recommendations should also be interpreted appropriately. The authors explicitly state that their recommendations represent their own opinions and are not intended to constitute a standard of care.
Because the teaching cases are composite presentations derived from real clinical cases, readers should also recognize that individual patients may present differently.
These limitations do not undermine the book's purpose; rather, they clarify where it fits within medical education: a focused emergency reference rather than a comprehensive neuro-ophthalmology textbook.
