Актуальность. Принципом факоэмульсификации является поддержание баланса ирригационно-аспирационных потоков. Баланс достигается за счет различных систем подачи жидкости, позволяющих хирургу задавать и поддерживать постоянный уровень ВГД во время операции. Вопрос об оптимальном безопасном уровне ВГД во время вмешательства на сегодняшний день остается открытым. Цель. Оценить влияние повышенного уровня интраоперационного офтальмотонуса на скорость кровотока в центральной артерии, вене сетчатки, и задних коротких цилиарных артериях. Материал и методы. В исследование было включено 29 пациентов с начальной катарактой. Факоэмульсификация выполнялась на приборе Alcon Centurion vision system на предустановленном интраоперационном уровне ВГД 60 мм.рт.ст. Скорость кровотока измеряли путем дуплексного сканирования в режиме ЦДК трёхкратно: до вскрытия глазного яблока, интраоперационно на уровне ВГД (58.77±8.28 мм.рт. ст) и сразу после герметизации доступа и нормализации ВГД. Каждое измерение сопровождалось контролем ВГД и АД. Результаты. При значении уровня ВГД 58.77±8.28 мм.рт. ст в ЦАС и ЗКЦА отмечалось статистически достоверное снижение максимальной систолической скорости кровотока. С 12,62±3,07 до 9,93±2,77 см/с и снижение конечной диастолической скорости кровотока с 3,94±1,09 до 1,79±1,64 см/с. В 11 из 29 (37,9%) случаев скорость кровотока в ЦАС в диастолическую фазу не регистрировалась. Максимальная систолическая скорость кровотока в ЗКЦЛА снизилась на 22%. Конечная диастолическая снизилась с 5,11±1,83 до 2,97±1,27 см/с. Аналогично, максимальная систолическая скорость кровотока с медиальной стороны упала с 12,37±2,74 до 9,50±1,68 см/с, а конечная диастолическая скорость кровотока снизилась с 4,54±1,35 до 2,73± 0,91 см/с. Скорость кровотока в ЦВС менялась незначительно и не зависела от уровня ВГД. Выводы. На уровне ВГД 58.77±8.28 мм. рт. ст. у человека отсутствуют компенсаторные механизмы ауторегуляции глазного кровотока в ответ на резкое повышение интраоперационного уровня ВГД, вплоть до полного прекращения кровотока в ЦАС в диастолическую фазу, что может приводить к ишемии тканей сетчатки.

Abstract Background A central retinal artery occlusion (CRAO) is an ophthalmic emergency due to its strong association with cerebrovascular and cardiovascular morbidity and mortality. A timely diagnosis is necessary but difficult in the setting of dense asteroid hyalosis, as typical fundoscopic findings can be obscured. We present a case where multimodal imaging in an eye with an obscured fundus could lead to timely diagnosis and management of CRAO in a patient with acute vision loss. Case presentation A 94-year-old Caucasian woman with a history of exudative macular degeneration presented to the retina clinic with acute vision loss in one eye over the course of an afternoon. The patient had dense asteroid hyalosis, and a direct retinal exam was not possible. Multimodal imaging suggested a CRAO diagnosis. The patient received digital ocular massage directly prior to undergoing fluorescein angiography (FANG), which confirmed the diagnosis. The patient was transported from clinic to the emergency room for an emergency stroke workup, which revealed a spontaneous echo in the left atrial appendage, and the patient was started on antiplatelet therapy. When she presented for follow-up within a week, the patient noted that her vision had improved at the time of digital ocular massage and continued to improve thereafter. Her FANG showed marked reperfusion of the retina, and she subsequently has completely regained her baseline visual acuity. Conclusions Multimodal imaging is useful in evaluating visual loss in patients with acute vision loss. In addition, ocular massage is a simple, low-risk intervention that may have benefit in the treatment of acute CRAO. Patients who present to ophthalmologists with an acute CRAO need an emergency referral for evaluation of cerebrovascular and cardiovascular comorbidities.

Background:Giant cell arteritis (GCA) is the most common form of systemic vasculitis in patients aged 50 years and older.1Visual symptoms such as amaurosis, diplopia, temporary or permanent visual field loss secondary to optic nerve ischemia are common manifestations.2The value of vascular ultrasound of extra-ocular vessels in diagnosing GCA is well established.3However, the role of transocular ultrasound of the central retinal artery in GCA patients has not yet been established.Objectives:To identify changes in flow velocities of the central retinal artery in GCA patients with visual symptoms and controls with transocular high resolution ultrasound.Methods:Prospective analysis of GCA patients with visual symptoms and controls. Ultrasound of the central retinal artery was performed in 18 newly diagnosed consecutive GCA patients with visual symptoms (GCA-group) and 25 controls without ocular pathology. Visual symptoms included amaurosis, diplopia and temporary or permanent visual field loss. For each eye, peak systolic values (PS) and end diastolic values (ED) were recorded. Furthermore, the resistance index of each central retinal artery was measured.Results:Twenty-one of 36 eyes of 18 GCA patients were affected. Therefore 21 central retinal were measured. The control group consisted of 50 central retinal arteries of 25 eye-healthy individuals. The mean age and gender distribution of the GCA-group were 75.6 years (SD± 8.1) with eight females (44 %) and 67 years (SD± 8.9) with twelve females (48%) in the control group. The mean flow velocity of the central retinal artery was PS 12.2 cm/s (SD± 3.5) and ED 3.7 cm/s (SD± 1.2) in the GCA group and PS 14.4 cm/s (SD± 3.2) and ED 5.1 cm/s (SD± 1.6) in the control group. The mean RI was 0.9 (SD± 0.3) in the GCA group and 0.8 (SD± 0.3) in the control group. Mean reduction in flow velocity in the GCA-group was PS 2.1 cm/s (p= 0.039) and ED 1.4 (p= 0.0004) cm/s, while the RI was increased by 0.14 (p= 0.077). The results for PS and ED measurements were statistically significant, while the results for RI were not significant.Conclusion:In GCA patients with ocular symptoms, a reduction of flow velocities of the central retinal artery compared to the eye-healthy control group was found. Results for PS and ED were significant. There seems to be a trend for decreased flow velocities in coexistence with visual symptoms in patients with GCA.References:[1]Warrington KJ, Matteson EL.

Purpose Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic complication of ovulation induction. It is a potentially lethal condition, with severe complications which include ovarian enlargement, and massive fluid redistribution from the vascular system into free spaces resulting in ascites, pleural effusion, electrolyte imbalance, hemoconcentration, hypovolemia, oliguria, and adult respiratory distress syndrome. Thromboembolism is a rare but extremely serious complication. Case Report We report a case of severe OHSS, presenting with central retinal artery occlusion (CRAO). Discussion This combination has not been reported previously.
