A Rare Case of Congenital Orbital Cystic Neuroblastoma in an Infant
Neuroblastoma, a relatively common tumor in infants, is rarely present at birth. A solid mass is the typical appearance of this neoplasm, while cystic formation is uncommon. Congenital cystic neuroblastoma is extremely rare and no previous report exists of its occurrence in the orbit. A newborn girl was referred with an extremely large mass on the right side of her face on the third day of her life. Prenatal ultrasonography had revealed a large mass (80 × 80 mm) in the frontal area. MRI revealed a heterogeneous mass composed of cystic and solid, contrast-enhancing components. Excisional biopsy was successfully performed and histopathologic diagnosis of neuroblastoma was confirmed. Systemic workup was negative for involvement of other organs and levels of catecholamine metabolites of serum and urine (homovanillic acid and vanillylmandelic acid) were normal. Postoperative course was uneventful with complete healing of the anophthalmic socket and normal physical and mental growth and development of the infant.
A Population-based Study on the Prevalence and Associated Factors of Age-related Macular Degeneration in Northern Iran the Gilan Eye Study
Purpose: To estimate the prevalence and associated factors of AMD in an Iranian population in 2014.Methods: In this population-based cross-sectional study, a total of 2975 Iranian residents (age: ≥50 years) from the urban and rural areas of Gilan province were included. The prevalence of different grades of AMD was determined using the International Age-Related Maculopathy Epidemiological Study Group grading system.Results: Of 2975 eligible individuals, 2587 (87.0%) subjects participated and 2275 (76.5%) subjects (62.6 ± 8.8 years old) had gradable fundus photographs. Age- and sex-standardized prevalence of early and late AMD based on the 2016 Iran census were 13.2% (95% confidence interval [CI], 10.6-16.2) and 0.7% (95% CI, 0.4-1.3), respectively.
A CASE OF NEUROFIBROMATOSIS TYPE 2 WITH UNUSUAL CLINICAL FEATURES
Purpose: To report a case of a neurofibromatosis Type 2 with unusual clinical features. Methods: Observational clinical case report. Results: A 22-year-old woman was referred with bilateral blurred vision and macular "scars." Ocular examination revealed bilateral posterior subcapsular and cortical cataract, optic disk swelling, hyperpigmented macular lesions, epiretinal membrane, and macular temporal dragging. Spectral-domain optical coherence tomographic imaging showed bilateral epiretinal membranes, peripapillary nerve fiber layer thickening, and vitreoretinal tractional bands. In the right eye, focal choroidal excavation was noted at the site of the macular lesion. In fluorescein angiography, mild vascular leakage, capillary nonperfusion, and ground glass hyperfluorescence was seen in temporal periphery of the right eye. Brain imaging showed intracranial calcification and vestibular schwannoma, which was removed by a neurosurgeon. A clinical diagnosis of neurofibromatosis Type 2 was made.
A Case Series of Infectious Keratitis After Corneal Cross-linking
Purpose: To present the 7-year experience of a tertiary eye hospital while exploring possible risk factors and incidence of infectious keratitis in patients undergoing standard corneal cross-linking (CXL). Methods: This retrospective cohort study included patients with progressive keratoconus undergoing standard CXL in the Farabi Eye Hospital and all other patients who had undergone CXL in other facilities and were diagnosed as having infectious keratitis in the 7-year period of the study. Results: Among the total of 4,863 eyes that underwent CXL, 6 eyes developed infectious keratitis, yielding an incidence rate of 0.12%. Additionally, 13 eyes from 10 patients with a CXL history in other facilities who developed infectious keratitis were included. The mean age was 23.75 years, and 75% of patients were men and 25% were women. Gram-positive bacteria and Staphylococcus aureus were the most prevalent pathogens. Meibomian gland dysfunction, dry eye disease, or blepharitis were present in 12 patients.
