Ocular and ophthalmic trauma has
increased tremendously in this world of modernization due to road traffic
accidents and many other day to day mishaps. The World Health Organisation
(WHO) had reported an annual occurrence of approximately 55 million eye
injuries with incapacitation for more than one day. There are more than 1.6
million blind people secondary to ocular trauma with an additional 2.3 million
having bilateral visual morbidity. 19 million people experience unilateral
blindness or low vision from preventable injury1. Moreover, there is
a global annual incidence rate of 3.5 open globe injuries per 100,000 persons,
resulting in approximately 203,000 open globe injuries annually worldwide2.
Globally, males are more prone to
sustain open globe injuries (80%) than females, most commonly from projectile
objects at work or home settings, while females and elderly patients are more
likely to experience globe rupture, most often from falls. Generally,
work-related injuries result from foreign matter striking or being rubbed into
the eye, and hence, manual labourers in production industries are most at risk.
Other mechanisms of injury include assault, sports, traffic accidents,
fireworks and gunshot wounds. The majority of intraocular foreign bodies (IOFB)
are small projectiles from metal and glass3-5.
A similar demographic pattern is seen
in children– the majority of them being boys aged 3 – 6 years experiencing
pointed metallic objects such as scissors, knives, writing instruments at home
or school settings. Other causative objects include wooden objects, toys, fire crackers.
Scenes of injury include streets, daycare centres and playgrounds6-8.
Predisposing and associated factors to
globe rupture include rural residence, alcohol consumption, cigarette smoking,
previous ocular procedures such as cataract surgery, penetrating keratoplasty
and LASIK (laser-assisted in situ keratomileusis) 9-12.
Ocular trauma thus has a significant
socioeconomic impact on the individual, family and society in general. In the
era of super specialization where we are uncomfortable managing disorders
outside our ophthalmic sub-specialty, it is imperative that we as
ophthalmologists and even non-ophthalmologists are formally trained in the
emergency and primary management of Ocular trauma before referral to an
appropriate institution with specialist for advanced management. Trauma thus
cuts across all specialties where broad principles with specific practice
patterns should be enforced.
Ocular trauma is an important component
of ophthalmic trauma. Ophthalmic trauma is a term hardly if ever used in
literature, but in its true sense constitutes both ocular and adnexal trauma. While
the literature is rife with terminology in ocular trauma, adnexal trauma is
often not taken into consideration as they are poorly addressed by the
ophthalmologist and sometimes delegated to non-ophthalmic specialties. We would
therefore like to propose use of the term Ophthalmic trauma in lieu of ocular
trauma to encompass all aspects of trauma that involve the globe and the
surrounding adnexal tissue. The Asia Pacific Ophthalmic Trauma Society (APOTS) was
thus constituted to promote the awareness about ophthalmic trauma in the
Asia-Pacific region, where the incidence of ophthalmic trauma is significantly higher.
Rest of the editorial will particularly emphasize on use of term “Ophthalmic trauma”.
Optimal care of a patient with
ophthalmic trauma is only possible if there is a well-orchestrated team and
care system to manage complex ocular and adnexal injuries. We herewith propose
an integrated pathway and care design to optimize outcome in a patient with
ophthalmic trauma. An interesting and poorly acknowledged entity is iatrogenic
ocular and adnexal injury which constitutes a significant cause of morbidity
caused and managed by the ophthalmologist and other related head and neck
surgical specialties. “Iatrogenic trauma” constitutes all the postoperative
surgical cases with surgically induced trauma and poorly managed open globe
injury cases. Most scientific ophthalmic conferences appear to address the
various intraoperative complications and their management, without addressing
them as ‘Iatrogenic ophthalmic trauma’. Dineen et al reported >12% of
blindness due to the sequelae of cataract surgery constituting iatrogenic
(surgical) and avoidable trauma13.
The model proposed below is about strategic planning of the
existing resources available at tertiary eye care centres. With the kind of
polytrauma load handled by all the tertiary eye care hospitals, heads of all
the tertiary eye care institutes/hospitals should set the tone for exclusive
dedicated ophthalmic trauma centres. These centres will not only serve the
patients and community but can also impart training to young ophthalmologists
and physicians from accident and emergency departments in the field of
ophthalmic trauma. We propose that
dedicated ophthalmic trauma specialist team will triage, work up & manage
all the patients with history of ophthalmic trauma and will subsequently manage
the complex cases with help of their subspecialty colleagues (vitreo-retina,
cornea, glaucoma, vitreo-retinal, oculoplasty and neuro-ophthalmology
colleagues). Complex adnexal trauma involving the upper and mid face may also
benefit from collaboration between the ophthalmologist / oculoplastic surgeon
and craniomaxillofacial teams.
Distinct role of ophthalmic trauma care unit:
1. Streamlining, triaging the patients
with ophthalmic trauma.
2. Emergency attendance and management of
patients with ophthalmic trauma. Adopt strict guidelines including Do's &
Don'ts.
3. Sharing/reducing the work-load of other
subspecialty colleagues.
4. Improving the quality of care and
monitoring outcomes of ophthalmic trauma patients.
5. Database for research, which will help
propose guidelines for prevention of ocular and adnexal trauma to reduce the
incidence of preventable ophthalmic trauma.
6. Central office for Ophthalmic Trauma
Registry.
7. Impart training and fellowship to young
ophthalmologists and emergency room physicians.
8. Conduct public forum / CME for
awareness about ophthalmic trauma
9. Foster collaboration and ties in field
of ophthalmic trauma between national and international organizations and
societies of related surgical sub-specialties.
All the above listed objectives can be
attained by setting the proposed Ophthalmic trauma care centres at the
internationally established tertiary eye and multispecialty institutions.
We suggest that the proposed dedicated ophthalmic trauma
care units can seek guidance and collaborate with national, regional and
international professional societies dedicated to Ophthalmic trauma. Some of
these include the International Society of Ocular trauma (ISOT), Asia Pacific
Ophthalmic Trauma Society (APOTS), American Society of Ocular Trauma (ASOT),
Ocular Trauma Society of India (OTSI) and Chinese Ocular Trauma Society (COTS).
Working with international organizations will foster knowledge, research and
collaboration. As open globe injuries present with management dilemmas with
many unresolved controversies, the proposed multidisciplinary dedicated unit
can setup guidelines and an algorithmic approach to manage those complex
injuries and to prevent ocular morbidity and optimize outcome by preventing
iatrogenic trauma. The unit could work in close coordination with primary and
secondary care units and will recognize and guide the junior ophthalmologists
in management of ophthalmic injuries, thereby aiding streamlining of management
of affected patients.
We have come a long way in the field of
ophthalmology from intracapsular cataract surgery to femtosecond laser assisted
surgery and from subjective macular assessment to non-invasive assessment of
retinal vasculature using optical coherence tomography angiography. The outcome
of globe injuries have improved with better understanding of complications and
improvement in surgical techniques. Despite numerous advances in technology and
knowledge, a considerable number of eyes still end up getting enucleated or
eviscerated following unsuccessful primary or secondary surgical repair. Factors
that lead to such unfortunate outcomes are manifold.
1. Ophthalmic
trauma is still being managed by the junior most ‘residents in training’ with
inadequate training and supervision. This results from the fact that ophthalmic
traumatology is yet to become an recognized discipline within Ophthalmology.
2. Inadequate
and incomplete evaluation and scoring to assess prognosis often results in
acceptance of suboptimal or even poor outcomes. Most ophthalmologists are
unfamiliar with the terminology of ophthalmic trauma and consider Ocular Trauma
Score (OTS) purely as just a research tool rather than a great scale for
prognostication.
3. Poor
communication between various disciplines of ophthalmology, and lack of timely
referrals to appropriate specialists or higher centres with subspecialty
expertise compound the problem.
4. Lastly,
there are no attempts to maintain an eye injury registry. All of the above can
be easily addressed and justified based on scientific and evidence based
outcomes, socioeconomic benefits but needs leadership amongst heads of
Ophthalmic units with political will as well.
We can prevent significant ocular morbidity
due to this devastating entity. The concept of a traumatic repair and
prevention of iatrogenic trauma needs to be ingrained into the strategic
planning in ophthalmic trauma management to achieve optimal outcome. Specialty
training of the fellow ophthalmologists with focused structured training in
ophthalmic trauma at one of the recognized centres in each country can be one
of the steps forward in optimizing the outcome in afflicted patients and
further streamline the care of traumatized eyes. Medico-legal litigation can be
minimized by good documentation, establishing rapport with the patient and
family and following the basic principles in management of ophthalmic trauma.
Dedicated efforts need to be put in to
buildup trauma registry and get the real life epidemiological data on
ophthalmic trauma. One of the most neglected parts in ophthalmic trauma is very
weak epidemiological data. Concentrated efforts should be made by the national
societies to mandate the reporting of eyes with all open globe and other severe
globe injuries in coordination with one of the international societies of
ophthalmic trauma. The epidemiologic data hence generated will guide the
regulatory agencies about the impact and burden of this problem and in terms of
health economics research will pave the way for boosting-up healthcare policy
and resources to prevent this gigantic but preventable cause of blindness. The
data generated will also highlight any obvious regional and national causes and
safety tools than need to be devised accordingly.
In summary, let us, each one of us, recognize, treat and
further develop Ophthalmic Trauma as a distinct subspecialty and become the
torch bearers to serve our patients even better.
