RESUMO Objetivo: O objetivo deste estudo foi investigar o volume plaquetário médio (MPV) de pacientes com oclusão da artéria da retina (RAO ABSTRACTPurpose: The aim of this study was to investigate the mean platelet volume (MPV) of patients with retinal artery occlusion (RAO). Methods: Thirty-seven patients diagnosed with RAO and 32 control subjects were included in this retrospective study. Retinal artery occlusion was diagnosed on the basis of clinical examination and fundus fluorescein angiography. All participants underwent complete ocular examination, and MPV, hematocrit, hemoglobin, and platelet counts were recorded. RAO patient data were compared with those of the control subjects.Results: Patients with RAO had significantly higher MPV values (7.96 ± 1.2 fL) com pared with control subjects (7.33 ± 0.7 fL, p<0.001). No significant difference was found with regard to platelet count between the RAO group and the control group (262 ± 70.1 × 10 9 /L and 251 ± 56.6 × 10 9 /L, respectively, p=0.50). MPV was an independent predictor of RAO [odds ratio (OR)=0.50; 95% confidence interval (CI)=0.28-0.89; p=0.019). Conclusions: Our results demonstrated that MPV values were significantly higher in patients with RAO, suggesting that larger platelets may contribute to the pathogenesis of the RAOs.

“…Then 4 (19%) people had a history of heart disease, which was divided into 1 right bundle branch block, 2 people heart failure, and 1 heart disease hypertension. The data has less value than the previous study in 2015 which showed 67% of CRAO patients to have a history of previous cardiovascular disease, of which 22% were coronary artery disease, 20% arterial fibrillation and 17% heart valve disease [4]. This is supported by a study from Sharma which states that every CRAO patient has an echocardiographic abnormality and is believed to have a 25x risk of cardioembolic events [11].…”

 Abstract: Central Retinal Artery Occlusion (CRAO) is an ophthalmologic emergency. Various systemic conditions can become risk factors. The purpose of this study is to discover the risk factors, and awareness of the emergency of patients with CRAO which is indicated by patient's onset-to-arrival time. The method used in this study is retrospective description from the medical record data of patients diagnosed with CRAO who comes to Saiful Anwar General Hospital for a period of 3 years. Sample collection is done consecutively, obtaining a total of 21 patients. The researched variables are age, visual acuity, risk factor, onset-to-arrival time, and acute-phase CRAO management success. Most of the CRAO patients found on this study are aged 60 years old, the highest amount of visual acuity upon arrival is 1/300, risk factor shows that 20 out of 21 samples have systemic hypertension, and almost all of the patients come for treatment 4-6 days after the onset. Most of the samples experience no change in their visual acuity after the therapy. The conclusion that hypertension is the highest risk factor of CRAO found on this study. The majority of patients come too late for treatment which causes not improving even worsening of their visual outcome.Zendy Sagita is general ophthalmologist graduated from Ophthalmology Study Program Faculty of Medicine Universitas Brawijaya and currently working in the same institution.

“…Combined unilateral simultaneous CRVO and BRAO is a rare condition, which if incomplete, has been proposed to be deemed as one entity. In patients with a combined concurrent CRVO and BRAO, an embolic compound has not been found, suggestive of the secondary nature of BRAO due to compression of the artery because of the obviously swollen optic nerve and/or central retinal vein resulting from CRVO [ 6 ]. This is the main distinction from an isolated BRAO, which often is caused by embolic events.…”

Detection of underdiagnosed concurrent branch retinal artery occlusion in a patient with central retinal vein occlusion using spectral domain optical coherence tomography

et al. 2014

BackgroundCombined branch retinal artery and central retinal vein occlusion is a rare condition that has been infrequently reported. This case report, aside from reporting the above-mentioned condition, highlights the importance of performing spectral domain optical coherence tomography in establishing a complete diagnosis, especially in uncertain and complicated cases. We also present spectral domain optical coherence tomography findings of a case of combined unilateral simultaneous central retinal vein and branch retinal artery occlusion.Case presentationWe present a single case of an initially missed, unilateral branch retinal artery occlusion combined with central retinal vein occlusion in a 51-year-old female Chinese patient without a significant past medical history, who experienced sudden, painless vision diminution in her right eye eleven days prior to presentation. She eventually recovered visual acuity to 0.60, despite having presented with poor vision.ConclusionCombined unilateral central retinal vein and branch retinal artery occlusion may occur in patients with no medical history of arterial hypertension and diabetes mellitus and can achieve a relatively good visual outcome. This case reaffirms the significance of performing a spectral domain optical coherence tomography examination in patients suffering from central retinal vein occlusion with suspicion of unilateral simultaneous branch retinal artery occlusion to identify the affected pathological areas.
