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.

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.

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.

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.

To our knowledge, incomplete central retinal artery occlusion associated with short posterior ciliary artery occlusion is extremely rare. Herein, we describe a case of a 62-year-old man who was referred to our hospital with of transient blindness in his right eye. At initial examination, the patient’s best-corrected visual acuity was 18/20 in the right eye. Fundus examination showed multiple soft exudates around the optic disc and mild macular retinal edema in his right eye; however, a cherry red spot on the macula was not detected. Fluorescein angiography revealed delayed dye inflow into the nasal choroidal hemisphere that is supplied by the short posterior ciliary artery. The following day, the patient’s visual acuity improved to 20/20. Soft exudates around the optic disc increased during observation and gradually disappeared. His hemodynamic parameters revealed subclavian steal syndrome as examined by cervical ultrasonography and digital subtraction angiography. We speculate that his transient blindness was due to ophthalmic artery spasms. In this particular case, spasms of the ophthalmic artery and occlusion of the short posterior ciliary artery occurred simultaneously. As the short posterior ciliary artery branches from the ophthalmic artery, the anatomical location of the lesion might be near the branching of both arteries.

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.

Arterial Thrombolysis

Background: Intra-arterial thrombolysis (IAT) for the treatment of acute central retinal artery occlusion (CRAO) has demonstrated variable results for improving visual acuity and remains controversial. Despite limited evidence, time from symptom onset to thrombolysis is believed to be an important factor in predicting visual improvement after IAT. Methods: A comprehensive review of the literature was conducted and individual subject level data were extracted from relevant studies. From these, a secondary analysis was performed. Initial and final logarithm of the minimum angle of resolution (logMAR) scores were either abstracted directly from relevant studies or converted from provided Snellen chart scores. Change in logMAR scores was used to determine overall treatment efficacy. Results: Data on 118 patients undergoing IAT from five studies were evaluated. Median logMAR improvement in visual acuity was -0.400 (p < 0.001). There was no significant association between logMAR change and time to treatment when time (hours) was described as a continuous variable or described categorically [0-4, 4-8, 8-12, 12+ h; or 0-6, 6-12, 12+ h]. Conclusion: The visual improvement observed in this series had no relationship to the time from symptom onset to treatment with IAT. This suggests that patients may have the possibility for improvement even with delayed presentation to the neurointerventionalist. Other factors, such as completeness of retinal occlusion, may be more important than time to treatment. Additional studies to determine optimal patient selection criteria for the endovascular treatment of acute CRAO are needed.

Purpose: We report a case of central retinal artery occlusion after filler injection for upper lid retraction. Diagnosis and treatment were performed to recover visual acuity and good results.Case summary: A 40-year-old woman presented to our clinic with upper lid retraction. She was diagnosed with hyperthyroidism and thyroid orbitopathy. She had been examined regularly at a local clinic since 2016. At the first visit, her visual acuity was 1.0/1.0 and the intraocular pressure was 19 mmHg, with no unusual findings in the anterior segment. Hyaluronic acid filler was injected into the medial part of the left upper lid. As soon as the needle was removed, she complained of blurry vision and visual impairment. This was followed by the development of a relative afferent pupillary defect; her visual acuity was hand motion at 30 cm. After 5 minutes, we performed wide fundus imaging and optical coherence tomography, which revealed retinal artery occlusion and a cherry-red spot, along with inner retina hyperreflectivity. Under a diagnosis of central retinal artery occlusion, we performed anterior chamber paracentesis, intravenous mannitol and acetazole injection, and an ocular massage. Approximately 1.5 hours after filler injection, retinal artery reperfusion and loss of the cherry red spot were observed and, after about 3 hours, her vision had recovered to 1.0 from hand motion at 30 cm.Conclusions: Central retinal artery occlusion after filler injection, when diagnosed promptly, can be treated by anterior chamber paracentesis, intravenous mannitol and acetazole injection, and ocular massage.

Abstract Background To present a series of acute central retinal artery occlusion (CRAO) cases showing internal limiting membrane detachment (ILMD) on optical coherence tomography (OCT) and to describe the possible etiopathogenesis and outcomes associated with it. Methods Demographic and OCT features of patients with acute CRAO were analysed retrospectively. OCT parameters noted were posterior vitreous opacities, ILMD, inner retinal layer stratification, hyperreflectivity and thickening, cystoid macular edema, neurosensory detachment. Eyes were grouped into Group (1) CRAO with ILMD; Group (2) CRAO with no ILMD. Results A total of 28 eyes of acute CRAO who had undergone OCT scans at the time of the acute episode were identified. Out of these, ILMD was noted in 5 eyes. The study findings suggested that cases of acute CRAO with ILMD are associated with poor presenting visual acuity and have more severe signs of retinal hypoperfusion on OCT, like inner retinal thickening, inner retinal hyperreflectivity and loss of inner retinal layer stratification. Patients with ILMD have poor final visual acuity and thinning and atrophy or necrosis of the inner retinal layers. Conclusion ILMD can occur in acute CRAO due to total retinal artery occlusion and severe retinal hypoperfusion. The presence of ILMD on OCT can be considered a sign of poor prognosis in cases of acute CRAO. Trial registration: Not applicable.
