Pediatric bacterial keratitis: clinical features, causative organisms, and outcome during a 13-year study period.

OBJECTIVE: To review the clinical features, causative organisms, complications, and outcomes of patients with pediatric bacterial keratitis at a tertiary care eye hospital. METHODS: We conducted a retrospective study at a tertiary care eye centre on clinically diagnosed pediatric patients with bacterial keratitis between 2007 and 2019. Poor outcomes were labelled if any of the following were present: final best-corrected visual acuity worse than 20/200, a drop in best-corrected visual acuity by 1 line or more, perforated corneas, endophthalmitis, and graft failure. RESULTS: The study included 43 cases of bacterial keratitis. Female and male patients represented 60.5% and 39.5% of the sample, respectively, with a mean age of 9.3 ± 5.9 years. The rate of culture positivity was 60.5%. The most common causative organisms were coagulase-negative Staphylococcus (23.1%), Pseudomonas (23.1%), and Streptococcus pneumoniae (19.2%). Culture-positive bacterial keratitis was associated with infiltrates ≥2 mm (p = 0.039), as determined by the results of multivariate analysis. Gram-positive and gram-negative bacteria exhibited 100% sensitivity to the tested fluoroquinolones. Complications included visually significant scars (55.8%), cataracts (14.0%), perforations (9.3%), corneal neovascularization (7.0%), nonhealing epithelial defects (7.0%), and endophthalmitis (4.7%). Corneal perforation was associated with the development of endophthalmitis (p < 0.001). On multivariate analysis, the only factor associated with a poor outcome was poor presenting visual acuity (p = 0.020). CONCLUSION: Gram-positive bacteria were the most common cause of pediatric microbial keratitis. Positive cultures were associated with larger infiltrates. The only adverse prognostic factor was poor presenting vision.

An Orbital Pseudotumor Secondary to Systemic Lupus Erythematosus: A Case Report.

Nonspecific orbital inflammation (NSOI), the primary cause of painful orbitopathy mostly in adults, can either manifest as localized or diffused. Periorbital edema or swelling is the most common sign followed by proptosis. NSOI or orbital pseudomotor secondary to systemic lupus erythematosus (SLE) is very uncommon in the Kingdom of Saudi Arabia. This is the first reported case from Saudi Arabia. The patient first presented to the outpatient department during her gestational period. Her chief complaint was right eye swelling and pain when she woke up in the morning. Her past medical history was positive for irritable bowel disease and SLE. A slit lamp examination revealed chemosis with conjunctival injections in the right eye and mild temporal chemosis in the left eye. Funduscopic examination after pupillary dilation revealed hyperemic discs with venous tortuosity more prominent in the right eye. Serum albumin level was low at 29 g/L. Orbital magnetic resonance imaging without contrast showed bilateral diffuse preseptal soft tissue swelling more prominent on the right side with diffuse bilateral congestion of intraorbital fat, including intraconal and extraconal fat. There was associated fat stranding around the optic nerves bilaterally. The bilateral extraocular muscles showed a diffusely increased T2 signal compatible with edema. The patient was given a bolus of intravenous methylprednisolone for three days. She had a satisfactory recovery. Early diagnosis is important to rule out other differential diagnoses, such as orbital cellulitis and lymphoma.

Painful Acute Corneal Ulceration and Anterior Stromal Keratitis in an Adolescent With Reactive Arthritis.

Reactive arthritis is occasionally associated with conjunctivitis and uveitis, but rarely keratitis. The authors describe a patient with paracentral anterior stromal keratitis with overlying epithelial erosion and multiple satellite subepithelial infiltrates. The initial appearance and the severe pain were suggestive of an infectious process. Recovery was rapid following introduction of topical steroid, with features suggesting an immune process in the recovery phase. The authors suggest that a history of arthritis and/or recent enteritis should be sought in the work-up of an atypical keratitis with or without epithelial defect.

Enlarging corneoscleral cyst in a 2-year-old girl.

Cysts rarely develop within the cornea or sclera of children with no previous history of trauma or surgery. Primary corneoscleral cysts may arise from proliferation of anomalously situated epithelial or endothelial cells. We report the case of a 2-year-old girl with a primary enlarging cyst situated at the limbus of her left eye. Optical coherence tomography was used to determine whether there was any communication between the cyst and the anterior chamber and to help plan appropriate management.
