introduction
The organ of vision is so arranged, that even the
most insignificant injuries can lead to decrease of
visual functions and even to blindness.
Results of the analysis of injuries of an organ of
vision show that more than 40% of complications
after injuries is connected with the wrong
evacuation of patients(Gundorovа R.А., Grishina
V.С., Polyakova М.К.).
introduction
Injuries of an eyeball and surrounding tissues :
 Contusions
 Penetrating wounds
 Non penetrating wounds
 Burns

 In our Republic the quantity of eye injuries
meets at 1-4 on 1000 population.

Contusions
Contusions of soft tissues and orbit
By localization of a trauma :
Contusions of soft tissues of an orbit
The closed fractures of bones of an orbit
On severity:
Easy (I)
Average (II)
Heavy (III)

Contusions of soft tissues
Symptoms:
- Subconjunctival hemorrhages
- The expressed hematoma of eyelids
- Restriction of the movement of an eyeball
Fractures of bones of an orbit
Damage mechanism
lower wall of an orbit
Symptoms:
- Diplopi

a) Change of a medial wall of an
orbit (emphysema of eyelids)
b) Change of external and lower
walls of an orbit on the right
c) Change of a upper wall of an
orbit, hematoma of eyelids
Tactics of fist aid
 First aid at injuries of surrounding soft tissues: to
place to trauma imposing of cold for 1-2 hours
(ice, wet towel wipes).
 Maintaining haemostatic vasoconstrictive
preparations (Vikasol, vitamin K, ascorutin,
calcium chloride of 10%).
 Immediately direct to ophthalmologist.
Eyeball contusions
By severity:
Easy – an absolute recovery
Average – small residual signs the functions
which aren't influencing on vision
Severe – significant morphological and
functional violations are observed
The most severe – Rough morphological
changes, loss of functions

Tactics of the first aid
 Instillation of antibacterial or sulphanilamyde eye
drops in conjunctival bag
 Anesthesia (local and general)
 Easy aseptic bandage
 Immediately direct to the ophthalmologist
Wounds of surrounding
tissues
By localization:
Wounds of eyelids
Wounds of lacrimal ways
Foreign bodies of an orbit
Wounds century
The fragmentary
wound of a lower eyelid
The fragmentary wound
of upper and lower eyelids
Wounds of lacrimal pathways
Separation of a lower eyelid with destruction
of lacrimal canalis
Foreign matter of an orbit
Foreign body (tree) is located in orbit and
trellised bosoms on the right (MR-the
tomogram).
Tactics of the first aid
 Introduction of an antitetanic anatoxin
 Wash of wound with disinfecting solutions
 Parenteral introduction of antibiotics
 Easy aseptic bandage

Tactics of the first aid
 Introduction of an antitetanic anatoksin
 Washings of a wound disinfecting solutions
 Parenteral introduction of antibiotics
 Binocular aseptic bandage
 Immediately direct to ophthalmologist
Treatment tactics
 Conducting the qualified help in conditions of
clinic:
 Orbit X-ray analysis in forward and lateral
projections
 Orbit X-ray analysis by Komberg – Baltin
 Primary surgical processing of wounds
 Carrying out reconstructive operations in a
planned order
Wounds of an eyeball

wounds of an eyeball

Thermal and chemical burns of
an organ of vision
Classification of burns of eyelids and conjunctiva
according to degree of burns of skin
other localizations
The I (easy) degree – a hyperemia and hypostasis
The II (average) degree – bubbles
The III (severe) degree – an ischemisation and necrotic
zones
The IV (heaviest) degree – necrosis of tissues
Thermal and chemical burns of
an organ of vision
By severity:
The I (easy) degree – a hyperemia of eyelids and
conjunctiva, hypostasis and a superficial erosion of
cornea
The II (average) degree – deep erosion and hypostasis of
cornea, ischemia of conjunctiva and limb
The III (severe) degree – joins cornea hypostasis in the
form of "opaque glass", necrotic zones of a conjunctiva
(scab)
The IV (the most severe) degree – a cornea in the form of
"porcelain glass", a total necrosis of conjunctiva and
perforation

Prevention of injuries of an organ of
vision
Prevention consists of 2 stages:
The first stage, i.e. primary prevention – carrying out
preventive measures among the population at home,
on streets, at schools, kindergartens.
The second stage, i.e. secondary prevention – early
diagnostics, carrying out urgent actions for active
complex drug and surgical treatment help to prevent
dangerous complications as purulent and phacogenic
uveitis, metallosis, hypotonia of an eyeball and a
sympathetic ophthalmia.
