Introduction. Central retinal artery obstruction (CRAO) represents an abrupt diminution of blood flow through the CRA that is severe enough to cause ischemia of the inner retina with permanent unilateral visual loss. We presented the role of color Doppler imaging (CDI) of orbital vessels and of extracranial duplex sonography (EDS) in the etiological diagnosis of CRAO in two patients with clinical suspicion of unilateral CRAO. Case report. Patients were examined following the protocol which included CDI of orbital vessels and EDS. Both patients had no emboli visible on ophthalmoscopy. The B-scan ultrasound evaluation of the first patient found a small round, moderately reflective echo within the right optic nerve, 1.5 mm behind the optic disc (emboli of cholesterol). CDI of retrobulbar vessels revealed the normal right ophthalmic artery (OA) hemodynamic parameters, but the first patient had no arterial flow signal on CDI at the distance of 1.5 mm behind the right optic disc. In contrast, the left eye had the normal aspect on CDI of retrobulbar vessels. The right internal carotid artery EDS identified a severe stenosis at its origin as CRA?s emboli source. The second patient had characteristic CDI findings for giant cell arteritis (GCA) with eye involvement: severe diminished blood flow velocities, especially end-diastolic velocities, in both CRAs. Less abnormalities were observed in the posterior ciliary arteries, and in the ophthalmic arteries. The second patient had no systemic symptoms or signs of GCA. Conclusion. In the presented cases, the ultrasound investigation enabled prompt differentiation between central retinal artery occlusion of embolic mechanism and CRAO caused by GCA.

Immunodeficiency Syndrome

Purpose In patients with acquired immunodeficiency syndrome (AIDS), disturbances in the circulation of retinal vessels are mostly encountered at the microvascular level. Rarely observed large retinal vessel occlusions frequently affect retinal veins. Methods A 32-year-old woman was admitted to the authors' clinic with sudden loss of vision. Her clinical and ophthalmologic examinations and laboratory tests were carried out and the results were evaluated. Results The patient's history revealed a diagnosis of AIDS established 5 years ago. Her corrected visual acuity was limited to light perception in the right eye and 20/60 in the left eye. There was afferent pupillary defect in the right eye. Posterior segment examination demonstrated central retinal artery occlusion in the right eye and cotton-wool spots in the left eye. The clinical examination and laboratory test results did not reveal any comorbid disease state that can contribute to this presentation. Conclusions As thrombi may develop in patients with human immunodeficiency virus infection, they should be closely followed up for the development of vasoocclusive disease.

Central retinal artery occlusion (CRAO) is a blinding event but not considered as a common emergency problem. Since awareness of the case is low, patients usually come to the ophthalmologist later than the golden period and havingthe worst prognosis. We report the case of patient with a central retinal artery occlusion that had visual improvement after emergency treatment.A 47-year-old woman with no comorbidities presented with symptoms of a sudden blurred vision, no pain or redness in the right eye (RE). Best-corrected visual acuity in the RE was 1/60. A relative afferent pupillary defect was observed in the RE. Ocular fundus examination of RE was suggestive of CRAO. Emergency treatment were performed, including rebreathing of expired CO2, ocular massage and ocular chamber paracentesis. One week later, the visual acuity was improved.This case highlights that fast and accurate response in acute management of CRAO should be conducted, especially within the golden hours which is less than 6 hours after the accident, to prevent permanent visual loss of thepatient.

Background. To report a patient with central retinal artery occlusion (CRAO) associated with sildenafil overdose. Case Presentation. A forty-two-year-old male presented three hours after sudden painless visual loss in the right eye. BCVA was counting finger in two meters, and relative afferent pupillary defect was positive. Fundus examination revealed retinal whiteness except in a limited area of papillomacular bundle and cherry red spot. He consumed two 100 mg film-coated sildenafil tablet (Vizarsin, Krka, d.d., Novo mesto, Slovenia) twelve hours apart, and the last one was six hours before visual loss. He was diagnosed with CRAO with cilioretinal artery sparing. Although we did not find any emboli, anterior chamber paracentesis was done. Four weeks later, BCVA improved to 20/80, with resolving of retinal edema. Cardiovascular, carotid arteries, and neurologic evaluations were negative for any predisposing factor. Conclusion. CRAO is a vision threatening condition that might be associated with the overdose of sildenafil.

Central retinal artery occlusion (CRAO) is a relatively rare form of acute retinal arterial ischemia that results in unilateral vision loss. The incidence of transient vision loss is estimated at approximately 14 cases per 100,000 people per year, while the incidence of CRAO is approximately 1–2 cases per 100,000 people. In the foreign literature, there are more and more publications about the development of iatrogenic vision loss after dermal cosmetic injections. We would like to present a clinical case that should be interesting for both practicing ophthalmologists and specialists of related specialties, especially for cosmetologists. Patient M., 42 years old, came to us with complaints of a sharp loss of vision to light perception in the right eye. From the anamnesis, it is known that two hours earlier, the patient was injected into the temporal region (plasma, anesthetic, epinephrine) in the cosmetology office. Lightning-fast deterioration of vision occurred at the time of the drug administration. The patient arrived at the clinic 2 hours after the onset of complaints. We conducted an ophthalmological examination of the patient, the diagnosis was made: occlusion of the central artery of the retina of the right eye, and immediately performed standard emergency therapy. After a course of conservative treatment in an ophthalmological hospital, a persistent decrease in visual functions and a violation of arterial blood circulation in the central retinal artery basin remained. The progressive increase in the number of minimally invasive cosmetic procedures in recent years, in particular, injections of dermal fillers, is associated with rare, but often fatal complications. This clinical situation should attract the attention of practicing ophthalmologists and cosmetologists to these types of complications, and improve the quality and speed of emergency medical care.

Subperiosteal Orbital Abscess

Central retinal artery occlusion (CRAO) is an ophthalmic emergency and has poor visual prognosis. It is commonly found in elderly people and very rare in child. We reported an 8-year-old girl who suffered from acute sinusitis, periorbital swelling, and the visual acuity of her right eye was only light perception. She was diagnosed with CRAO, SPOA (subperiosteal orbital abscess), and acute sinusitis. Emergency treatments including surgery, antibiotics, glucocorticoids, intraocular-pressure-lowering drugs, and vasodilators were taken immediately in order to save the eyesight. The visual acuity of the right eye returned to 20/400. Conclusions: Severe intraorbital complications of acute sinusitis can lead to CRAO. Timely drainage, strong antibiotics, and glucocorticoids are the most effective methods for the treatments.
