RESUMEN
BACKGROUND: Dengue fever is a mosquito-borne illness prevalent mainly in the tropics. It is feared for causing the dengue hemorrhagic spectrum of the disease leading to significant morbidity and mortality. Its rarer manifestations are categorized as the expanded dengue syndrome, and though being recognized, they are not fully appreciated and understood. The involvement of the eye in dengue fever is one such phenomenon. CASE PRESENTATION: A 27-year-old South-Asian woman presented on day 2 of dengue fever, without capillary leakage, for further management. Despite developing hepatitis, she had an otherwise uncomplicated progression of the illness because she did not develop capillary leakage. On day 8 of the illness, she had the lowest platelet count and developed bilateral blurred vision. Examination revealed that only gross movements were detected in the left eye, and the right eye had a visual acuity of 6/9. She was diagnosed with foveolitis in the right eye and central serous chorioretinopathy in the left eye, along with hemorrhages in both eyes. These were confirmed by funduscopy, fluorescein angiography, optical coherence tomography, and macular scans. She received systemic and intravitreal steroids and was assessed regularly. After 6 months of observation, her visual acuity was 6/6 in the right eye and 6/9 in the left eye, which remained the same thereafter. DISCUSSION: The exact mechanism of eye involvement in dengue viral infection is poorly understood. Multiple causes have been suspected and include viral factors, immune mediation, capillary leakage, stress, and hemorrhage. Eye involvement is classically seen at the lowest platelet count and when the count begins to rise. Though symptoms are nonpathognomonic, blurring of vision is the commonest complaint, but the range of presentation is extensive and variable. Ophthalmological assessment and funduscopy are very useful in addition to advanced assessments. There is no clear consensus on management; suggestions range from conservative care to aggressive steroid therapy with immune modulation and even ophthalmological intervention. Recovery can be full or partial with a variable time scale. CONCLUSION: The extensive spectrum of possible visual symptoms should prompt the clinician to suspect any visual complaint as potential dengue eye involvement. Guided studies and screening are needed to better understand the true incidence of eye involvement in dengue fever.

In India, the dengue disease has attained an unprecedented proportion with a sharp increase in the size of human population at risk recently. Presentation of the disease varies from asymptomatic illness to haemorrhagic manifestations and shock. Previously ocular findings were considered rare in dengue fever; but due to increased number of cases various types of ocular complications are described in present day case series. Here, is presented a case of a girl with serologically proven dengue fever who developed a subhyaloid premacular haemorrhage in one eye with superficial retinal haemorrhages and cotton wool spots in both eyes.

PURPOSE: To describe ocular findings of patients with Crimean-Congo hemorrhagic fever (CCHF). DESIGN: Prospective, interventional, consecutive case series. METHODS: This study was conducted in Sivas, a city located in the central Anatolia, between July 1 and August 31, 2007. Confirmed CCHF patients were enrolled in the study and underwent ocular examination during hospitalization. RESULTS: Nineteen confirmed CCHF patients were included in this study. All patients were classified into 2 groups in terms of disease severity (severe vs nonsevere), according to the Swanepoel predictive criteria. Fourteen patients (73.7%) were classified as "nonsevere," and the remaining 5 patients (26.3%) were classified as "severe" in this study. One patient having severe disease died. Ocular findings were present in 14 patients (73.7%) and none of the patients presented any visual complaints. Ocular examination revealed that 7 patients (36.8%) had only bilateral multiple subconjunctival hemorrhage, and 2 patients (10.5%) (1 bilateral, 1 unilateral) had retinal hemorrhage. Five patients (26.3%) had subconjunctival hemorrhage and retinal hemorrhage. Follow-up examination 1 month later showed complete resorption of the subconjunctival hemorrhage and retinal hemorrhage. There was a statistically significant difference between patients with ocular findings and patients without ocular findings for prothrombin time (P = .011). There was no evidence of uveitis, retinal edema, sheathing of retinal vessels, or intravitreal hemorrhage in our patients. CONCLUSION: From the small sample study, CCHF caused a mild form of ocular disease. CCHF must be considered when subconjunctival or superficial retinal hemorrhages are seen in association with fever in endemic areas.

PURPOSE: To present ocular findings in a measles epidemic outbreak among young adults. METHODS: Ophthalmic lesions in an unselected group of 61 young military personnel with measles were followed. Eighteen of the patients had symmetric keratitis in both eyes. They were treated with diclofenac sodium eyedrops qid in the right eye, while the left eye was observed untreated. The disappearance of the corneal lesions in both eyes was compared. RESULTS: Forty patients (65.6%) had measles conjunctivitis with bulbar and tarsal conjunctival hyperemia. Five (8.2%) had increased mucous secretion. Thirty-five (57.4%) had superficial punctate corneal epithelial and subepithelial lesions which stained with fluorescein. Ten patients had corneal lesions without evident conjunctival pathology. Fourteen patients had subconjunctival hemorrhages, 12 of whom had bilateral lesions mostly in the superonasal quadrant. The time to disappearance of corneal lesions was 4.5+/-3.2 days in the diclophenac-treated right eyes, and 4.1+/-3.8 days in the left eyes. We did not observe a significant difference in the healing time between the two eyes (p = 0.75). CONCLUSION: Measles did not cause major ocular complications in healthy patients. Keratitis was unresponsive to diclophenac sodium eyedrops with respect to healing time and end result.
