Periorbital ecchymosis and subconjunctival hemorrhage due to leech therapy for headache / Equimose periorbital e hemorragia subconjuntival devido à terapia com sanguessugas para dor de cabeça

ABSTRACT A 62-year-old woman was admitted to our clinic with the complaints of periorbital ecchymosis and subconjunctival hemorrhage that are visible, especially on the right eye. We noted that her complaints began the day after she underwent leech therapy on the glabella area for headache. On the glabella, 2 leech bites were observed close to the right side. Examination revealed ecchymosis on the bilateral eyelids and subconjunctival hemorrhage on the inferolateral and medial limbus on the right eye. No treatment was initiated, rather control measures were recommended. The follow-up after 1 month revealed that the patient's complaints had disappeared.(AU)

RESUMO Uma paciente de 62 anos procurou nosso ambulatório com queixas de equimose periorbital e hemorragia subconjuntival, visíveis principalmente no olho direito. Descobrimos que suas queixas começaram no dia seguinte a um tratamento para dor de cabeça com sanguessugas na área da glabela. Na glabela, 2 mordidas de sanguessuga foram encontradas próximas ao lado direito. Durante os exames da paciente, foram detectadas equimoses nas pálpebras bilaterais e hemorragia subconjuntival no limbo ínfero lateral e medial do olho direito. Nenhum tratamento foi iniciado, sendo recomendado apenas controle. No acompanhamento, observou-se que as queixas da paciente desapareceram em cerca de um mês.(AU)

Diferentes abordajes en el manejo de las hemorragias maculares: reporte de casos y revisión de literatura / Different approaches in the management of macular hemorrhage: case reports and a literature review

INTRODUCCIÓN: Las hemorragias maculares producen una pérdida de la visión súbita y profunda. Las principales modalidades de tratamiento incluyen observación, inyección intravítrea de fármacos antiangiogénicos, hialoidotomía con láser neodymium-doped yttrium aluminium garnet, inyección intravítrea de gas y/o activador de plasminógeno tisular, en monoterapia o combinadas con cirugía. En el presente trabajo reportamos cuatro casos de hemorragias maculares de distintas causas, tratadas con diferentes abordajes, y realizamos una revisión de la literatura al respecto. PRESENTACIÓN DE CASOS: Los cuatro pacientes mostrados presentaron diferentes causas de hemorragias maculares. El primer caso tuvo una hemorragia prerretiniana debido a retinopatía de Valsalva y fue tratado con cirugía, el Caso 2 tuvo una hemorragia macular multinivel debido a una rotura de un macroaneurisma arteriolar retiniano y fue manejado con desplazamiento neumático, láser y ranibizumab intravítreo, el Caso 3 presentó una hemorragia subretiniana extensa debido a rotura coroidea posterior a un trauma ocular cerrado de alta energía y fue tratado exitosamente con cirugía. El último caso presentó una hemorragia prerretiniana debido a retinopatía diabética, manejada con láser neodymium-doped yttrium aluminium garnet. Los diferentes tratamientos fueron realizados exitosamente con buenos resultados. CONCLUSIÓN: Existen amplias opciones disponibles para el manejo de las hemorragias maculares y la mejor opción depende de las características de cada caso en particular. El manejo apropiado y oportuno de éstas puede lograr un resultado visual bueno, especialmente si la localización de la hemorragia es prerretiniana.

INTRODUCTION: Macular hemorrhages result in a sudden and profound loss of vision. The primary treatment modalities include observation, intravitreal injection of antiangiogenic drugs, neodymium-doped yttrium aluminum garnet hialoidotomy, intravitreal injection of gas with or without tissue plasminogen activator, as monotherapy or combined with surgery. In this paper, we report four cases of macular hemorrhages of different causes treated with different approaches, and we review the literature in this regard. CASE PRESENTATION: All four patients presented different causes of macular hemorrhage. The first case had a preretinal hemorrhage due to a Valsalva retinopathy and was treated with surgery. Case 2 had a multilevel macular hemorrhage due to a rupture of a retinal arteriolar macroaneurysm and was treated with pneumatic displacement, laser, and intravitreal ranibizumab. Case 3 presented an extensive subretinal hemorrhage due to a choroidal rupture after high-energy ocular trauma that was also successfully treated with surgery. The last case was a preretinal hemorrhage due to diabetic retinopathy managed with neodymium-doped yttrium aluminum garnet laser. Different treatment approaches were successfully performed in all cases with good outcomes. CONCLUSION: There is an extensive range of options available for the management of macular hemorrhages, and the best option depends on the characteristics of each particular case. Proper and timely management of these diseases can achieve an excellent visual outcome, especially if the location of the hemorrhage is preretinal.

Spontaneous microscopic hyphema secondary to iris vascular tufts: Case report with video documentation

A 71-year-old woman presented with spontaneous microhyphema in her left eye, causing blurry vision. Bleeding stopped spontaneously shortly after several cycles of digital compression on the upper eyelid, (which were documented in video), and therefore, did not require laser photocoagulation, a possible approach previously explained to the patient. A microhemangioma at the edge of the iris was identified to be the cause of the condition. The hemorrhage did not recur during the follow-up period (9 months).

Effect of Huoxue-Huayu decoction and carbogen on the serum inflammatory factors and visual field defect in patients with diabetic retinopathy / 国际中医中药杂志

Objective To investigate the effect of the promoting blood circulation to Huoxue-Huayu decoction combined with carbogen for diabetic retinopathy (DR). Methods A total of 76 DR patients who met the inclusion criteria were divided into 2 groups by random number table method, 38 cases in each group. Both groups were given the routine hypoglycemic treatment, and the control group added the treatment of calcium oxybenzosulfonate tablets, wihle the treatment group added the Huoxue-Huayu decoction. Both groups were treated for 2 months. The FPG, 2 hPG and HbAlc were detected by automatic biochemical analyzer. The serum levels of hypersensitive c-reactive protein (hs-CRP) and Serum cystatin C (Cys C) were detected by immuno-transmission turbidimetry. The serum homocysteine (Hcy) was determined by radioimmunoassay. The serum transforming growth factor β1 (TGF-β1) and il-6 were detected by the ELISA. The serum glutathione peroxidase (GSH-Px) was detected by colorimetry. The Fluorescence fundus angiography was used to detect the area of macular edema, the number of microangiomas and the area of bleeding focus. The Visual field defect was examined under normal pupils to evaluate the clinical efficacy. Results The total effective rate was 84.2％(32/38) in the treatment group and 60.5％ (23/38) in the control group, with statistically significant difference (χ2=5.331, P=0.021). After treatment, the serum levels of FPG and HbA1c in the treatment group were significantly lower than those in the control group (t values were 2.059 and 2.081, respectively, all Ps<0.05). The Serum Hcy, Cys C, hs-CRP, TGF-β1, IL-6 levels in the treatment group were significantly lower than those in the control group (t values were 4.575, 2.799, 19.520, 6.614, 10.644, P<0.05 or P<0.01), while the GSH-Px levels were significantly higher than the control group (t=10.483, P<0.01). Compared with the control group after treatment, the number of microangiomas in the treatment group decreased, the area of bleeding focus decreased, the gray scale value of the visual field decreased, and the area of macular edema decreased (t values were 7.543, 3.923, 4.957 and 6.691, all Ps<0.01). Conclusions The Huoxue-Huayu decoction combined with carbogen can reduce the degree of visual field defect , reduce the inflammatory reaction and improve the clinical effect for DR patients.

Macular hemorrhage after roller coaster riding in a single-eyed patient with congenital glaucoma / Hemorragia macular após passeio em montanha russa em paciente monocular com glaucoma congênito

ABSTRACT A 21-year-old female presented with a 4-day history of decreased vision in her only functional eye (right eye, OD). She had a history of multiple ocular surgeries in both eyes because of congenital glaucoma and had lost light perception in her left eye several years prior. Ophthalmological examination revealed 0.15 Snellen visual acuity, and fundoscopy revealed nearly total cupping and pallor of the optic disc and multiple retinal hemorrhagic foci in the macula in OD. Lesions spontaneously resolved over a few months. Gravitational forces during a roller coaster ride may have caused this macular hemorrhage.

RESUMO Uma paciente de 21 anos de idade se apresentou com perda de visão há quatro dias em seu único olho com visão útil. Ela tinha uma história de cirurgias oculares múltiplas nos dois olhos devido a um glaucoma congênito e perda de percepção luminosa em olho esquerdo há muitos anos. O exame oftalmológico revelou acuidade visual de Snellen de 0,15 e na fundoscopia foi observada escavação do nervo óptico quase total e palidez de papila, assim como focos hemorrágicos múltiplos na região macular. As lesões se resolveram espontaneamente em alguns meses. Acreditamos que essas hemorragias maculares tenham sido causadas pelas forças gravitacionais geradas durante o passeio na montanha russa.

Anatomic and functional outcome of eyes with massive submacular hemorrhage secondary to retinal macroaneurysm submitted to vitrectomy

Purpose: To report the anatomic and functional outcome in patients with severe visual loss after acute massive submacular hemorrhage secondary to retinal arterial macroaneurysm submitted to vitrectomy and subretinal recombinant tissue plasminogen activator injection. Methods: Retrospective, observational, case-series of 4 eyes of 4 patients submitted to pars plana posterior vitrectomy (ppV) combined with internal limiting membrane (ILM) removal and subretinal recombinant tissue plasminogen activator (rtPA-12.5 mg/0.1 ml) injection with dilute (20%) sulfur hexafluoride (SF6) gas in the vitreous cavity of eyes with recent onset (≤7 days) massive macular hemorrhage due to retinal arterial macroaneurysm (RAMA). Optical coherence tomography (OCT) was obtained both at presentation and during follow up. Results: Patients ranged in age from 63 to 78 years and all had systemic arterial hypertension. Visual acuity at presentation ranged from hand motions to count fingers at 50 cm. All eyes showed extensive retinal hemorrhage involving more than two-thirds of macular area. The time between the onset of symptoms and the surgery ranged from 3 to 7 days. After a mean postoperative follow-up of 15.5 ± 5.19 months (range, 10-22 months), all eyes showed visual acuity improvement and final visual acuity ranged from 20/30 to 20/80. All had complete displacement of the subretinal hemorrhage from the fovea after the surgery. OCT images showed neurosensory retina thinning and disruption of the reflective line that represents the junction between inner and outer photoreceptors segments (IS/OS line) beneath the macular area and absence of the external limiting membrane (ELM). Conclusions: ppV associated with subretinal rtPA injection with intravitreal gas seems to be a safe and effective technique to promote visual improvement in patients with multilevel macular hemorrhage secondary to RAMA. Despite functional improvement, OCT images demonstrate that...

Objetivo: Relatar os resultados anatômicos e funcionais em uma série de pacientes com perda visual grave por hemorragia submacular maciça aguda secundária a macroaneurisma arterial de retina (MAR) e descrever a técnica cirúrgica utilizada. Métodos: Este é um estudo retrospectivo, observacional, série de casos, incluindo 4 olhos de 4 pacientes que foram submetidos à cirurgia de vitrectomia posterior (VP), associada a peeling da membrane limitante interna (MLI) e injeção sub-retiniana de ativador do plasminogênio tecidual recombinante (rtPA-12,5 mg/0.1 ml) por hemorragia submacular maciça recente (≤7 dias) secundária MAR. Em todos os casos, o exame de tomografia de coerência óptica (OCT) foi obtido na consulta inicial e nas subsequentes para avaliação das alterações estruturais da retina. Resultados: A idade dos pacientes variou entre 63 a 78 anos e todos apresentavam hipertensão arterial sistêmica. A acuidade visual inicial nos olhos afetados variou de movimento de mãos a conta dedos a 50 cm. Todos os olhos apresentaram hemorragia retiniana extensa ocupando mais do que dois terços da região macular. O tempo decorrido entre a perda visual e a cirurgia variou entre 3 a 7 dias. Após um seguimento médio de 15.5 ± 5.19 meses (variando entre 10 a 22 meses), a acuidade visual pós-operatória variou entre 20/30 e 20/80. Todos os olhos apresentaram um deslocamento completo da hemorragia subretiniana da região macular central no pós operatório. As imagens seccionais da retina obtidas pela OCT revelaram um afilamento da retina neurossensorial e interrupções na linha refletiva que representa a junção entre os segmentos internos e externos dos fotorreceptores na região macular, além de falhas na membrane limitante externa em todos os casos. Conclusão: De acordo com os resultados do presente estudo, a VP associada à injeção sub-retiniana de rtPA parece ser uma técnica segura e eficaz em promover melhora visual em pacientes com hemorragia submacular...

Relationship between optic disc hemorrhage and localized retinal nerve fiber layer defect in normal-tension glaucoma / 中华眼底病杂志

Objective To investigate the relationship between optic d isc hemorrhage and localized retinal never fiber layer defects (RNFLDs) in norma l-tension glaucoma. Methods In 83 patients with normal-tensi on glaucoma, the cumulative frequency and quadrantal distribution of optic disc hemorrhages were retrospectively analyzed. The neighboring relation between opti c disc hemorrhages and RNFLDs in a same quadrant and the changes of correspondin g retinal never fiber layer (RNFL) after the occurrence of optic disc hemorrhage s were observed by tridimensional photochromy of ocular fundus. Results (1) The occurrences and distribution of optic disc hemorrhages: 29 of 83(34.94%) patients (33 eyes) had totally 58 occurrences, including 39 in infer iotemporal area, 14 in superiotemporal area, and 5 in other area. (2) The relati onship of neighborhood between optic disc hemorrhages and RNFLDs: in the availab le tridimensional photochrome, 23 occurrences in 15 patients (16 eyes) were foun d with cuneiform RNFLDs in the same quadrant, in which 22 was near the border of cuneiform RNFLDs. (3) The changes of corresponding retinal never fiber layer (R NFL) after the occurrence of optic disc hemorrhages: the photochromes of 24 occu rrences in 20 patients (21 eyes) were kept well in the initial and the 2-year f ollow-up periods, while the changes of RNFL were found in each region correspon ding to the 19 occurrences (in inferiotemporal or superiotemporal area) in the i nitial photochrome, including 7 cuneiform defects with various sizes, and 12 dev eloped localized RNFLDs next to the initial hemorrhages in the optic disc. No ob vious localized RNFL corresponding to the other 5 occurrences (1 in inferiotempo ral, 1 in superiotemporal, and 3 in other areas) were found in the follow-up pe riod. Conclusion Optic disc hemorrhages in normal-tension gla ucoma occur mostly in inferiotemporal area, and secondly in superiotemporal area of optic disc, and the appearance of optic disc hemorrhages may suggest that th e localized RNFLDs would develop in the associated regions.

Effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage / 中华眼底病杂志

Objective To explore the effects of vitrectomy on neovascular glaucoma combined with vitreous hemorrhage. Methods Seven eyes of 7 patients with neovascular glaucoma combined with vitreous hemorrhage underwent vitrectomy combined with phacoemulsification, panretinal photocoagulation, and trabeculectomy. The preoperative visual acuity ranged from light perception to 0.2, and the mean preoperative intraocular pressure was 54 mm Hg (38-64 mm Hg)(1 mm Hg=0.133 kPa). The mean follow-up was 8 months (6-15 months). Results The postoperative visual acuity ranged from light perception to 0.4, and the mean postoperative intraocular pressure was 17 mm Hg (10-30 mm Hg) which was significantly lower than preoperative one ( P

Comparison of fundus fluorescein angiography and indocyanine green angiography for imaging of subretinal hemorrhage in age-related macular degeneration / 中华眼底病杂志

Objective To compare the effects of fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) on classifications and locations of choroidal neovascularization (CNV) located under subretinal hemorrhage in age-related macular degeneration, and on the area-measuring of subretinal hemorrhage. Methods The medical record of 177 patients with subretinal hemorrhage associated with AMD confirmed by photochrome of ocular fundus, FFA and ICGA examinations were retrospectively reviewed. The locations and classifications of CNV on the images of FFA and ICGA in the 177 patients and the area of subretinal hemorrhage of 30 patients randomly selected from the 177 patients were analyzed and measured. Results On the images of FFA, the locations and classifications of CNV could be defined in 160 patients (90.4%), and CNV was considered eligible for laser therapy in 24 patients (13.6%). On the images of ICGA, the locations and classifications of CNV could be defined in 175 patients (98.9%),and CNV was considered eligible for laser therapy in 51 patients (28.8%). There was no statistical difference of the locations (Z=-0.383,P=0.701) and classifications (?2=2.993,P=0.810) of CNV on the images of FFA and ICGA. The areas of blocked fluorescence measured on the images of FFA (=26.610 mm2 and M= 13.548 mm2) were larger than those of ICGA (=24.714 mm2, M=12.875 mm2) with statistical differences (Z=-3.000,P=0.003) between FFA and ICGA. Conclusions ICGA is beneficial for imaging CNV located under subretinal hemorrhage, and may increase the number of the patients who are considered eligible for laser treatment. The effect of measurement of the area of subretinal hemorrhage in AMD evaluated by FFA is better.

Establishment of a hemorrhagic retinal detachment model in rabbits / 中华眼底病杂志

Objective To establish a hemorrhagic retinal detachment (HRD) model for the study of the damage and treatment of HRD. Methods Fourteen rabbits (28 eyes) were divided into the HRD (12 eyes) and control (16 eyes) group randomly. Autologous anticoagulated blood (0.2 ml) was transvitreally injected into the rabbits′ subretinal space with a special glass micropipette in HRD group (12 eyes); while 0.2 ml saline with or without heparin sodium (2.5 U/ml) was respectively injected into subretinal space respectively of the rabbits in heparin saline control group (6 eyes) and saline control group (3 eyes); furthermore, another 2 control groups, i.e.,pseudo injection group (3 eyes, single retinal puncturing without subretinal injection) and normal group (4 eyes of 2 normal rabbits) were also set. The conditions of the occurrence and representation of the retinal detachment (RD) were observed and analysed by means of ophthalmoscopy, optical coherence tomography (OCT) and ultrasound A and (or) B scan examinations in the subsequent 28 days after the operation. Results After the operation, HRD occurred in all eyes of the rabbits in HRD group. The area of HRD extended from 10 to 12 disc diameter(DD). The obvious elevation of RD maintained to 14 days, and the residual subretinal hemorrhage was still observed till 28 days. The obvious RD of the rabbits in heparin saline and saline control group was only kept for no more than 12 hours. The retinal puncture hole in pseudo injection group disappeared 2 days after the operation, and there was no change in retina of rabbits in normal control group. Conclusion It is convenient, practical and effective to establish a HRD model by means of transvitreal subretinal injection of autologous anticoagulated blood.

The Use of Contrast-Enhanced Color Doppler Ultrasound in the Differentiation of Retinal Detachment from Vitreous Membrane

OBJECTIVE: To compare the clinical utility of contrast-enhanced color Doppler US in the differentiation of retinal detachment (RD) from vitreous membrane (VM) with that of various conventional US modalities, and to analyze the enhancement patterns in cases showing an enhancement effect. MATERIALS AND METHODS: In 32 eyes examined over a recent two-year period, RD (n=14) and VM (n=18) were confirmed by surgery (n=28) or clinical follow-up (n=4). In all cases, gray-scale, color Doppler, and power Doppler US were performed prior to contrast injection, and after the intravenous injection of Levovist (Schering, Berlin) by hand for 30 seconds at a dose of 2.5 g and a concentration of 300 mg/mL via an antecubital vein, contrast-enhanced color Doppler US was performed. At Doppler US, the diagnostic criterion for RD and VM was whether or not color signals were visualized in membranous structures. RESULTS: Diagnostic accuracy was 78% at gray-scale US, 81% at color Doppler US, 59% at power Doppler US, and 97% at contrast-enhanced color Doppler US. The sensitivity of color Doppler US to color signals in RD increased from 57% to 93% after contrast enhancement. The enhancement patterns observed were signal accentuation (n=3), signal extension (n=2), signal addition (n=3), and new signal visualization (n=5). CONCLUSION: Contrast-enhanced color Doppler US was the most accurate US modality for differentiating RD from VM, showing a significantly increased signal detection rate in RD.

Morphological analysis of hemorrhage of optic disc in normal-tension glaucoma / 中华眼底病杂志

Objective To study prospectively the morphological relations among hemorrhage of optic disc, defect of retinal nerve fiber layer, and peripapillary atrophy in normal-tension glaucoma (NTG). Methods Qualitative and quantitative methods were applied to evaluate the relations among hemorrhage of optic disc, defect of retinal nerve fiber layer, and peripapillary atrophy by using stereo ocular fundus photography and computer analyzer systems. Results In 37 patients (42 eyes) in NTG hemorrhage group, 50 hemorrhagic spots at optic disc was found, including coloboma of retinal nerve fiber layer in 35 eyes (83.3%)(35/42). In 35 patients (40 eyes) in non-hemorrahge group, partial coloboma of retinal nerve fiber layer was found in 21 eyes (52.5%)(21/40). The difference of incidence of coloboma of retinal nerve fiber layer between the two groups was not significant (?2=1.403, P=0.236). The incidence of atrophic arc in hemorrhage group differed much from which in non-hemorrhage group (?2=7.008, P=0.008). The area of atrophic arc at ?section in hemorrhage group [(2.05?0.88)mm2] was significantly different from which in non-hemorrhage group [(1.42?0.53)mm2] (t=-2.618, P=0.012). In the follow-up period, the difference of incidence of disc-rim loss between hemorrhage and non-hemorrhage group was significant, (?2=5.802, P=0.016); while the difference of the incidence of visual field defect between the two groups was not. Conclusion In eyes with NTG, hemorrhage of optic disc, coloboma of retinal nerve fiber layer and atrophic arc are closely related. More disc-rim loss and changes of atrophic-arc area in hemorrhage group in the follow-up period suggests that hemorrhage of optic disc is the risk factor of development of NTG.

Surgical treatment of massive subretinal hemorrhage and vitreous hemorrhage associated with age-related macular degeneration / 中华眼底病杂志

Objective To investigate the method and the effects of the surgical treatment of massive subretinal hemorrhage and vitreous hemorrhage associated with age related macular degeneration. Methods A retrospective study of 14 consecutive patients underwent a complete pars plana vitrectomy. Retinotomy was carried out for removing subretinal hemorrhage by using balanced salt solution. Complete air fluid exchange and gas or silicone oil tamponade were performed in all patients. The follow up period was within 3～7 months. Results Atrophy of eyeball in 2 eyes (14.3%) postoperatively. Improvement of corrected final visual acuity and anatomical retinal reattachment were achieved in 12 (85.7%) of the 14 eyes postoperatively. Seven days after operation, muddy sand hemorrhage in anterior chamber occurred in 4 (28.6%) of the eyes and paracenteses of anterior chamber were performed for these eyes. Conclusion Surgical intervention should be applied in the eyes with the massive subretinal hemorrhage associated with age related macular degeneration in order to avoid the affected eyes becoming atrophic due to the subsequent complication of vitreous hemorrhage, anterior chamber muddy sand hemorrhage,ghost cell glaucoma or retinal detachment.

THE CLINICAL FEATURE OF SUBRETINAL AND VITREOUS HEMORRHAGE ASSOCIATED WITH SENILE MACULAR DEGENERATION / 解放军医学杂志

To study the clinical feature and surgical outcome of subretina and vitreous hemorrhage associated with senile macular degeneration (SMD). Vitrectomy was performed in 29 eyes of 29 patients with subretina and vitreous hemorrhage associated with SMD. Changes in the retina were observed, and the results of surgery were analyzed. The results showed that there was submacular hemorrhage in 16 patients, in whom 4 showed periomacular subretinal hematoma. There was peri macular subretinal hematoma only in 13 cases. The pathological changes in the macular region included discoid degeneration, submacular neovascularization, fixed foldings, exudation, scar and atrophic discoid cicatrization. All patients got visual acuity improvement after surgery. However those patients who had subretinal hemorrhage got less improvement of visual acuity than the others. It suggested that the SMD patients who was complicated by subretinal hemorrhage had a severer macular lesion. Pars plana vitrectomy could restore central vision of patients who suffered from subretinal and vitreous hemorrhage. But the outcome was related with the position of subretinal hemorrhage.
