20 Home Remedies to Get Rid of Sinus Infection
Acute dacryocystitis
Acute dacryocystitis is fulminant acute infection of the lacrimal sac, usually staphylococci, occurring in case of obstruction of lacrimal. The infection progresses within hours with an inflammatory major distension of the lacrimal sac. It requires urgent treatment because it can spread quickly and cause orbital cellulitis. Or sepsis, especially in newborns and immunocompromised. Usually the causative organisms are staphylococci. Proper treatment is: - hospitalization - Removal of secretions to direct examination, culture and sensitivity, blood cultures.

Orbital Cellulitis
life threatening infection affecting the entire orbit
organisms; strep pneumoniae, staph aureus, strep pyogenes
symptoms - fever, peri-ocular pain, inflamed lids, diplopia, pain with eye movement
signs - reduced eye movements, proptosis
optic nerve dysfunction --> reduced vision, pupillary defects
can lead to abscess formation, thrombosis, meningitis
Management = IV antibiotics, surgery for abscess
Orbital cellulitis
Background: the orbital septum
The orbital septum is a fibrous sheet which is attached peripherally around the margin of the orbit where it is continuous with the periosteum. Centrally, it fuses into the tarsal plates. It effectively separates the eyelids from the contents of the orbital cavity.
Description
Acute, spreading infection involving the fat and/or muscle within the bony orbit posterior to the orbital septum
Orbital cellulitis is an extremely serious (potentially life-threatening) but uncommon ophthalmic emergency characterised by infection of the soft tissues behind the orbital septum.
Preseptal cellulitis refers to the much more common and far less serious infection anterior to the orbital septum. Very occasionally, preseptal cellulitis progresses to orbital cellulitis; this is more likely in children. Orbital cellulitis and preseptal cellulitis are not terms that can be used interchangeably.
Synonym(s): Postseptal cellulitis
Investigations
Diagnosis is usually made based on the clinical findings and investigations are aimed at identifying the root cause of the infection - particularly in the case of orbital cellulitis. Investigations are carried out in the hospital setting.
FBC frequently shows a leukocytosis (>15 X109) but blood cultures are frequently negative in adults. They cannot be counted on to differentiate between preseptal and orbital cellulitis.
Any discharge from skin breaks should be swabbed and sent to microbiology. Throat swabs and samples of nasal secretions may also help diagnosis.
CT of the sinuses as well as the orbit ± brain:
CT is usually indicated only for children (unless the child is very well and the episode is mild) or if orbital cellulitis is suspected in an adult.
if an intracranial abscess is suspected, CT is the gold standard imaging modality, carried out to identify any subperiosteal abscesses, paranasal sinusitis or cavernous sinus thrombosis (all needing multi-speciality input).
It is also valuable in assessing trauma where there may be concerns about a retained orbital or intraocular foreign body.
MRI may complement the CT in diagnosing a cavernous sinus thrombosis. If cerebral or meningeal signs develop, the patient may need a lumbar puncture. However a lumbar puncture is contra-indicated for suspected orbital cellulitis until a CT scan has ruled out raised intracranial pressure.[11]
Alert
Prompt diagnosis and intervention are critical, since delayed treatment can result in sustained or permanent vision loss, intracranial complications, and even death.
Epidemiology
Occurs more commonly in the winter because of increased incidence of sinusitis (12)[C]
No racial predilection or difference in frequency between the sexes in adults
More common in children. Male > Female (2:1).
The median age of children hospitalized with orbital cellulitis is 7–12 years.
Risk Factors
Continuous sinusitis is the most common risk factor, accounting for up to 80–90% of cases (1,3)[C].
Orbital trauma
Dental or intracranial infection
Retained orbital foreign body
Preorbital or facial cellulitis
Facial skin infection (i.e., impetigo, infected insect bite, acne, eczema)
Acute dacryocystitis
Acute dacryoadenitis
Orbital mucopyocele
Ophthalmologic surgery (for strabismus or detached retina, blepharoplasty, radial keratotomy, peribulbar anesthesia)
Management
Emergency referral
Emergency referral to secondary care is required for:
All children
Any patient with any indication of possible orbital cellulitis
All patients who are systemically unwell
Occasions where there is doubt over the diagnosis
A patient not responding to treatment; or
When drainage of a lid abscess is required
Preseptal cellulitis[4][12]
Most children are initially admitted to hospital (even for preseptal cellulitis) unless there is good reason not to. This may be just for 24 hours. Children should be considered to have orbital cellulitis until proven otherwise (ie repeated examinations normal, good response to antibiotics in first 24 hours and normal CT scan).
Oral co-amoxiclav may be used for both adults and children as long as there is no allergy to penicillin. Clinical improvement should occur over 24-48 hours.
Hospital management may involve intravenous therapy (eg, intravenous ceftriaxone until response is seen) and further investigation to confirm that this is indeed a simple preseptal cellulitis and that there are no unusual organisms involved.
ENT will be involved if sinusitis is found.
Orbital cellulitis
Hospital admission under the joint care of the ophthalmologists and the ENT surgeons is mandatory.[2]
Intravenous antibiotics are used (eg, cefotaxime and flucloxacillin) in addition to metronidazole in patients over 10 years old with chronic sinonasal disease.[3]
Clindamycin plus a quinolone such as ciprofloxacin are used where there is penicillin sensitivity. Vancomycin is also an alternative.
Optic nerve function is monitored every four hours (pupillary reactions, visual acuity, colour vision and light brightness appreciation).
Treatment may be modified according to microbiology results and lasts for 7-10 days.
Surgery is indicated where there is CT evidence of an orbital collection, where there is no response to antibiotic treatment, where visual acuity decreases and where there is an atypical picture which may warrant a diagnostic biopsy. Surgery often concurrently warrants drainage of infected sinuses.[4]
Genetics
No known genetic predisposition
General Prevention
Appropriate treatment of bacterial sinusitis
Proper postoperative wound care
Pathophysiology
Orbital cellulitis usually occurs as a result of:
Extension of an infection from the periorbital structures (usually the paranasal sinuses, especially ethmoid sinusitis) and also from the face, the globe, the lacrimal sac and dental infection (via an intermediary maxillary sinusitis).
Occasionally, it may occur as an extension of preseptal cellulitis, particularly in young children in whom the orbital septum is not fully developed.[1]
Direct inoculation of the orbit from trauma (accidental or surgical - including orbital, lacrimal, strabismus and vitreo-retinal surgery). Post-traumatic orbital cellulitis tends to develop within 72 hours of the injury.
Haematogenous spread from distant bacteraemia.
The pathogens most commonly involved are the aerobic, non-spore-forming bacteria - Streptococcus pneumoniae, Staphylococcus aureus, Streptococcus pyogenes and Haemophilus influenzae (the latter mainly found in children).[2]
Mucormycosis associated with patients who have diabetic ketoacidosis or immunosuppression is also described.[3] This very rare and rapidly spreading infection caused by fungi, is aggressive and often fatal.[4]
There has recently been an emergence of Meticillin-resistant S. aureus (MRSA) in the organisms isolated; this is rare but the development is worrying.[5] Orbital cellulitis may be complicated by spread to adjacent structures and to the central nervous system.

Clinical Pearls
Most of orbital cellulitis cases result from contiguous sinusitis.
Patients should be admitted to the hospital for monitoring and IV antibiotic treatment if orbital cellulitis is diagnosed.
Ophthalmoplegia, mental status changes, contralateral cranial nerve palsy, or bilateral orbital cellulitis may herald intracranial involvement.
Ophthalmology and otolaryngology should be consulted early when orbital cellulitis is suspected.
Complications
Preseptal cellulitis
Progression of infection to orbital cellulitis, especially in young children.
Unusually, lagophthalmos (inability to close the eyelids completely over the globe), lid abscess, cicatricial ectropion and lid necrosis may also occur.
Orbital cellulitis[4]
Ocular: exposure keratopathy (which can lead to visual loss through permanent damage to the cornea), raised intraocular pressure, central retinal artery or vein occlusion, endophthalmitis, optic neuropathy.
Orbital abscess: more often associated with post-traumatic orbital cellulitis. Blindness can occur through direct extension of the infection to the optic nerve.
Subperiosteal abscess: usually located along the medial orbital wall. This may progress intracranially.
Intracranial (rare): meningitis, brain abscess, cavernous sinus thrombosis.
