Orbital Cellulitis After Strabismus Surgery

Serious infection is uncommon after eye muscle surgery. Orbital cellulitis is a rarely reported but is potentially vision- and life-threatening complication after strabismus surgery. In this report, we describe a case of unilateral orbital cellulitis after strabismus surgery for sensory exotropia in a healthy adolescent boy.     

Orbital Cellulitis after Faden Operation on the Medial Rectus

Background Orbital cellulitis after strabismus surgery is uncommon, may cause blindness and may lead to death. Very few cases have been described in detail due to the low incidence of this complication. Methods We report the first case of orbital cellulitis following Faden operation on the medial rectus muscle. We believe that the infection was due to asymptomatic ethmoid sinusitis. Our case is compared with other cases previously reported. Results A two-year-old boy was surgically treated for residual esotropia after two botulinum toxin A injections. Two days after surgery, signs of orbital cellulitis developed in his right orbit. CT-scan disclosed right ethmoid sinusitis that spread to the orbit after surgery. After intravenous antibiotic treatment, the infection resolved with full restoration of visual acuity and ocular motility. Conclusion Despite adequate measures to prevent infection, orbital cellulitis may complicate strabismus surgery. Patients must be instructed to recognize early symptoms of this severe infection and call the surgeon immediately. Diagnosis may be confirmed by CT-scanning of the orbits. Prompt treatment with intravenous antibiotics usually leads to full recovery.     

Orbital cellulitis following surgery of strabismus

The authors report a case of orbital cellulitis after strabismus surgery. Diagnosis was confirmed by computerized tomography. Subsequent therapy and follow-up are discussed. Attention is drawn to the importance of this syndrome.     

Neonatal Orbital Abscess after Sinus Surgery: Case Report and Brief Review

ABSTRACT

Orbital abscess formation in neonates is rare, with only 12 cases reported in the literature. We present a case of orbital cellulitis with orbital abscesses following repair of congenital choanal atresia in a 2-week-old neonate. This is the first reported case of an orbital abscess following a sinus procedure in a neonate.     

Giant orbital cysts after strabismus surgery

PURPOSE: To describe a rarely reported complication of strabismus surgery. DESIGN: Observational case series. METHODS: A review of four eyes in three patients with orbital cysts following strabismus surgery. RESULTS: Each patient had either a symptomatic strabismus or visible mass that brought them to medical attention many years, often decades after surgery (mean 34 years). All had some degree of incomitancy. During surgery, all cysts were found to be associated with the involved rectus muscle. CONCLUSIONS: Orbital cysts are a rarely recognized complication of strabismus surgery. However, it should be considered in the differential of orbital cysts after strabismus surgery because of the risk of muscle damage during surgical excision.     

Infected conjunctival pyogenic granuloma at strabismus surgery site mimicking conjunctival abscess

We present a rare case of infected pyogenic conjunctival granuloma mimicking a conjunctival abscess as complication of strabismus surgery in a Saudi girl with exotropia. Despite administration of local antibiotics following strabismus surgery, a patient presented with localised redness and discharge after three weeks. The patient was afebrile with no signs of pre-septal or orbital cellulitis. After culture (Staphylococcus aureus) sensitivity testing the patient was prescribed oral Amoxicillin and Clavulanate and reviewed under general anaesthesia. A 55?mm² conjunctival pyogenic granuloma was noted. A punch biopsy specimen indicated inflammatory and histiocytic cells. The addition of steroid to the medical therapy resulted in a quiet eye after three weeks.     

Scleral buckle induce orbital cellulitis and scleritis – A case report and literature review

We report a case of a young healthy patient who developed orbital cellulitis and scleritis after retinal detachment surgery that was repaired with a scleral buckling procedure. Once scleral implant infection occurs, orbital infection results requiring removal of the implant in all previous reported cases. However, our patient was treated with systemic antibiotic and steroids without the need for removal of the scleral buckle.     

Orbital complications after aqueous drainage device procedures

A retrospective case series of 2 patients with orbital complications after tube shunt placement for glaucoma is reported. The first patient presented with limited motility and conjunctival injection in the setting of intraocular gas leakage in the superior orbit after previous vitreoretinal surgery. The second patient presented with multiple signs of orbital cellulitis. Both patients improved with intravenous antibiotics. Although rare, orbital complications may occur after glaucoma tube shunt surgery.     

Postoperative myositis in reoperated extraocular muscles.

PURPOSE: To report on a series of patients who developed orbital myositis following routine strabismus surgery. METHODS: A retrospective medical record review of patients who developed myositis following routine strabismus surgery. Surgery was performed on all patients between 1998 and 2003 by a single pediatric ophthalmologist (SMA). RESULTS: Four patients developed orbital myositis following routine strabismus surgery. All four cases were reoperations. Symptoms of myositis developed at a mean of 21 days after surgery (range, 4-34). In the initial patient, the diagnosis of myositis was based on clinical and computed tomography findings. The clinical course of the three subsequent patients was similar to that of the radiologically confirmed case. In all cases, the diagnosis was supported by rapid resolution after treatment with systemic corticosteroids. CONCLUSIONS: Orbital myositis is a previously unreported complication of strabismus surgery. Reoperation appears to be a predisposing factor.     

Orbital cellulitis as a postoperative complication of sub-Tenon anaesthesia in cataract surgery

Orbital cellulitis is a rarely reported sight-threatening complication of sub-Tenon anaesthesia. We report a case of orbital cellulitis in a patient who had received sub-Tenon anaesthesia for routine cataract surgery. We discuss the potential under-reporting of complications of sub-Tenon anaesthesia that had a delayed presentation, and the possible association between the use of hyaluronidase in the anaesthetic mixture and orbital cellulitis following sub-Tenon anaesthesia.     

Blinding orbital cellulitis: a complication of strabismus surgery

A 56-year-old healthy man underwent left medial rectus recession and lateral rectus resection for esotropia. The next day he developed severe left periocular pain with decreased vision, an afferent pupillary defect, periorbital edema, limited ocular motility, and proptosis. Computed tomography showed fat stranding and less than 90 degrees of posterior globe tenting. Despite intravenous antibiotics to treat orbital cellulitis, and a lateral canthotomy and cantholysis to decompress the orbit, visual acuity worsened to no light perception. The patient underwent emergent orbital decompression including release of the superior and inferior septum and outfracturing of the orbital floor and medial wall; however, there was no recovery of vision. Blinding orbital cellulitis is a rare complication after strabismus surgery. Despite poor prognosis, prompt diagnosis and aggressive treatment may maximize visual potential.

Acute acquired comitant esotropia after orbital cellulitis

Acute extraocular muscle restriction in children is a rare condition; orbital myositis is the most common cause. Most neuropathic or myopathic causes of strabismus present as an incomitant deviation. We report a case of orbital cellulitis preceding acute comitant esotropia in a patient showing no evidence of myositis or neurologic pathology.     

Neonatal orbital abscess

PURPOSE: To describe two cases of orbital abscess in neonates and to review the literature of orbital cellulitis in neonates. DESIGN: Two interventional case reports. METHODS: Photographs, orbital computed tomography scans, and full pediatric examination were obtained in two cases of orbital abscess in neonates. RESULTS: Acute ethmoiditis with orbital abscess formation was found in both infants. In one of them, Staphylococcus aureus was identified as the source of infection. CONCLUSIONS: The clinical findings of our cases concur with the literature (eight cases) indicating that orbital abscess caused by Staphylococcal ethmoiditis is the most common form of orbital cellulitis in neonates.

Periorbital and orbital cellulitis before and after the advent of Haemophilus influenzae type B vaccination

OBJECTIVE: To evaluate the effect of the introduction of the Haemophilus influenzae B (Hib) vaccine (introduced first in 1985, then extended in 1990 to children at least 2 months of age) on the epidemiologic features of periorbital and orbital cellulitis. DESIGN: Retrospective, comparative case series. PARTICIPANTS: Three hundred fifteen pediatric inpatients. METHODS: Children at Massachusetts General Hospital and Massachusetts Eye and Ear Infirmary with discharge diagnosis of periorbital or orbital cellulitis from 1980 through 1998 were reviewed. MAIN OUTCOME MEASURES: Case rate, culture-positive isolates, and associated conditions. RESULTS: A total of 297 cases of periorbital cellulitis and 18 cases of orbital cellulitis were reviewed. Before 1990, there were 27 cases of Hib-related cellulitis (11.7% of total in that period), whereas after 1990, there were only three (3.5% of total; P = 0.028). The number of cases per year was significantly lower after 1990 (21.2 +/- 10.4 vs. 8.7 +/- 3.9; P = 0.008), as were the number of positive culture isolates (for any organism) after 1990 (76 [33. 0%] vs. 9 [10.6%]; P < 0.001). The medical conditions most commonly associated with periorbital cellulitis were sinusitis (44 [14.5%]) and upper respiratory infections (73 [26.6%]). All cases of orbital cellulitis were associated with sinusitis. CONCLUSIONS: The introduction of the Hib vaccine coincided with a sharp decline not only in the number of periorbital and orbital cellulitis cases related to H. influenzae, but also in the annual case rate. These data are consistent with a facilitative role for H. influenzae in the development of cellulitis secondary to other pathogens. They also may support restriction of the spectrum of antibiotics used to manage these conditions.     

Retrobulbar hemorrhage following strabismus surgery

Retrobulbar hemorrhage, although a well-known complication of retrobulbar injection, periocular injections, and periocular surgeries, is not routinely associated with strabismus surgery. We present a case of delayed orbital hemorrhage occurring in a young boy 2 days after strabismus surgery.     

Odontogenic orbital cellulitis

PURPOSE: To describe a small series of patients with odontogenic orbital cellulitis and review the visual outcomes of such patients reported in the scientific literature. METHODS: Review of medical records and the scientific literature. Measured parameters included gender, age, days to presentation and surgery, the need for surgical intervention(s), sinus and orbital involvement on CT imaging, and pathogens involved. RESULTS: Current cases and review of the scientific literature resulted in 24 patients with odontogenic orbital cellulitis and adequate examinations for statistical analysis. Twelve of 24 patients had preserved vision (final vision better than 20/70), whereas 11 of 24 patients had vision loss (final vision of light perception or no light perception). Analysis of data showed no statistical correlation between visual loss and age (p = 0.81), days to clinical presentation (p = 0.45), days to surgical exploration (p = 0.96), sinus radiographic involvement (p = 0.50), orbital radiographic findings (p = 0.19), or type of bacterial infection (Gram-positive aerobic vs. anaerobic organisms), (p = 0.31 and p = 0.50 respectively). Male gender, the need for surgical drainage, and multiple surgical procedures performed correlated statistically with loss of vision (p = 0.05, p = 0.03, and p = 0.02, respectively). CONCLUSIONS: Multiple case reports have demonstrated that orbital cellulitis from an odontogenic source can result in devastating visual loss. Male gender, the need for surgical drainage, and multiple surgical procedures correlated statistically with severity of visual loss.     

Orbital cellulitis following cataract surgery

Orbital cellulitis is an extremely uncommon complication following cataract surgery. Herein, a patient who developed orbital cellulitis less than 24 h after undergoing cataract surgery is described. She responded well to systemic antibiotic treatment and ultimately achieved good visual acuity in the affected eye. The most likely mode of pathogen entry in such cases is considered to be the anaesthetic block given before the cataract surgery. It has been suggested that a careful skin antiseptic preparation before the block is given could prevent this occurrence, but such a preparation did not do so in our case.
