INTRODUCTION
• Ocular trauma is common, preventable yet the most under-recognized major health problem today. Blindness due to injury is a social and economical burden for every individual. Optimizing visual outcome in ocular injury requires prompt diagnosis and treatment. 1,2, 3
• With the introduction of the Birmingham Eye Trauma Terminology System (BETTS), the documentation of ocular trauma has been standardized.4
• In practice, BETT only concerns mechanical eyeball injury. As a result, eye lid, orbital and ocular adnexa injury cannot be classified by BETT, although part of orbital and ocular adnexa injuries associated with globe injury can be categorized into globe injury by BETT, this classification is still incomplete and misses some information. BETT was proposed 12 year before so it needs some additional information regarding eye lid, orbital and ocular adnexal injuries. 5,6
AIMS & OBJECTIVES• To implement modification in Birmingham Eye Trauma Terminology System
classification for ocular trauma.
Classification of Mechanical Ocular Injuries according to BETT
Study Design:• Prospective And Retrospective Cohort Study.• All patients with ocular trauma in either eye, diagnosed and managed between
January 2002 to December 2015 at Drashti Netralaya, Dahod were included in the study, and patients consenting to participate were included.
Inclusion Criteria:• All patients coming to Drashti Netralaya with ocular trauma.
Exclusion Criteria: • Severe trauma to other body parts. • Patient with ocular trauma, already treated for the same in any other hospital. Sample size: • 4721
MATERIALS & METHODS
Examination Protocol:• For each patient enrolled, we obtained a detailed history, socioeconomic data, details of
the injury, and information on the eye treatment and surgery performed to manage past ocular trauma. Data for both the initial and follow-up reports were collected using the online BETTS format of the International Society of Ocular Trauma. Details of the surgery were collected using an online form.
• Visual Acuity on presentation of both eyes , Anterior Segment examination by Slit Lamp Biomicroscopy, Posterior Segment examination by Indirect Ophthalmoscope and if media was not clear, then a B-scan was performed to evaluate the posterior segment.
• The surgical technique was selected according to the morphology and the condition of tissues other than the lens. In all patients undergoing corneal wound repair, the traumatic cataract was managed in a second procedure.
• The duration of medical treatment depended on the degree of inflammation in the anterior and posterior segments of the operated eye.
• Data was exported from electronic medical record system, collected in excel sheets and analyzed.

OLD CLASSIFICATION NEW PROPOSED CLASSIFICATION
DISCUSSION• Ocular trauma is believed to be one of the significant cause of visual impairment. It can cause a
wide variety of damage to the ocular tissues.• Trauma generally occurs in the younger age group and in males who are commonly involved in
outdoor activities. It is comparatively rare in old age and in females. Most of the people sustain injuries during work, which in a rural setup includes agricultural activity most commonly.
• Trauma can cause a variety of damage to the ocular tissues. This damage can involve both the anterior and posterior segment. The damage can be relatively mild or can be very severe, leading to loss of vision. In mild cases, medical management is sufficient whereas in severe cases, early surgical intervention such as paracentesis, globe repair and vitrectomy is required to restore some useful vision.
CONCLUSION• Standardized international classification of mechanical eyeball injury proposed by BETT
considering incomplete, we propose a new classification of mechanical eye injuries. This classification nearly includes all mechanical eye injuries to makes epidemiological study and clinical records easier.
