RESUMO

A boy in his mid-teens presented with progressively increasing bleeding from the right eye and nostril intermittently over a period of 6 weeks. A complete ophthalmic examination revealed nothing significant. His otorhinological examination and haematological investigations were within normal limits. The patient came a month later with frank bleeding from the right eye. Ophthalmic examination revealed hyperaemia and maceration of the right lower palpebral conjunctiva. A histopathological examination of conjunctival scrapings from the site showed abnormal dilated blood vessels suggestive of a vascular malformation. Digital subtraction angiography confirmed the presence of a conjunctival micro arteriovenous malformation supplied by the external carotid and ophthalmic artery branches. He underwent successful transarterial Onyx embolisation resulting in complete resolution of the haemolacria.

RESUMO

Epithelioid hemangioendothelioma is a rare vascular tumor originating from vascular endothelial or pre-endothelial cells. We present the case of a 4-month-old male with a rapidly enlarging left zygomatico-orbital tumor causing mass effect on the eye globe. Examination revealed a large, nontender, solid lesion. CT angiography showed no major feeder or intralesional vessels. Complete surgical excision was performed, which was complicated by life-threatening intraoperative bleeding and successfully controlled with electrocautery. Microscopically, tumor cells exhibited varying morphologies. Immunohistochemistry confirmed the diagnosis of epithelioid hemangioendothelioma (positive for CD31 and CD34, negative for CK AE1/AE3). We also highlight 2 similar case reports with life-threatening bleeding complications. Surgeons should be aware of this condition and optimize surgical preparation, including blood products, to manage potential bleeding complications.

RESUMO

Hemolacria, or bloody tears, is a symptom caused by several ocular disorders ranging from trauma to hormonal changes. We describe a case in which a 21-year-old, 28-week pregnant patient presented to the emergency department (ED) following her second occurrence of nocturnal left eye bleeding in a week. During her examination in the ED, a small abrasion to the lateral edge of the upper left lid was noted. No other injuries, traumatic mechanisms, or relevant past medical history were noted. Due to her pregnancy, the nascent pyogenic granuloma responsible for her hemolacria was managed conservatively. Despite management, the pyogenic granuloma rapidly grew within a few weeks causing ocular irritation and conjunctival injection. Due to concerns about ocular irritation, inability to close the affected eyelid, and decreasing visual acuity, the pyogenic granuloma was removed surgically. This case highlights the difficulty in managing pregnant patients with ocular complaints who initially present to the ED. In this case, the patient's pregnancy complicated her initial treatment plan, requiring more conservative initial management strategies. While conservative first-line treatment options for pregnant patients are recommended, they should be paired with constant risk-benefit assessment for the patient and her fetus.

RESUMO

OBJECTIVE: Ocular hemorrhages (OHs) may cause visual disturbances and incidence vary from 18 to 39% in newborns. Precipitated/instrumental delivery and perinatal asphyxia were predefined risk factors. Acidosis can interfere with coagulation and disrupt the pressure of ocular capillaries and put infants with moderate acidosis with or without hypoxic-ischemic encephalopathy at risk for OH. We aimed to evaluate the OH in neonates with fetal acidosis. STUDY DESIGN: Neonates >34 weeks are included if pH < 7.10 and BE < -12 mmol/L within the first hour. Ophthalmologic examinations for retinal (RH), vitreous, and anterior chamber (hyphema) hemorrhage were done within the third day. RH was staged according to Egge's classification. Follow-up of the patients was continued until the age of 2. Clinical characteristics of newborns were analyzed. RESULTS: Sixty-two neonates (38 ± 2.3 weeks, 2,971 ± 612 g) were included. pH = 6.91 ± 0.16, BE = - 17.2 ± 5.3 mmol/L. OH was found in 22 (36.7%) neonates (hyphema n = 2, vitreous n = 2, RH n = 21). Thirty-eight eyes with RH were staged (Stage 3: n = 15 [39.5%]; Stage 2: n =11 [28.9%]; Stage 1: n = 12 [31.6%]). Vaginal delivery (OR: 4.9, 95% CI [1.4-17.8]) and advanced resuscitation at the delivery room (OR: 8.8; 95% CI [1.9-41.7]) were found to increase the risk of RH. CONCLUSION: Approximately one-third of neonates with moderate to severe acidosis exhibited RH when examined on the third day. Contrary to previous studies that reported mild RH in otherwise healthy neonates, our findings revealed that neonates with moderate to severe acidosis predominantly presented with Stage 3 RH. While the higher incidence of RH in vaginally delivered infants is consistent with previous studies, the identification of advanced resuscitation as a risk factor is a new addition to the literature. The findings in our study highlight the importance of retinal examination in neonates with acidosis in the presence of intubation during resuscitation. KEY POINTS: · One-third of neonates with moderate to severe acidosis exhibited RH.. · Stage 3 RH was identified as the most prevalent.. · Advanced resuscitation was identified as an independent risk factor for RH..

RESUMO

RESUMO Objetivo: Avaliar o efeito do colírio de brimonidina 0,2% na redução da hiperemia e do sangramento ocular durante as cirurgias de estrabismo, em comparação com o colírio de nafazolina 0,025% + feniramina 0,3%. Métodos: Foram avaliados 14 pacientes com estrabismo e indicação de correção cirúrgica bilateral. Foi instilado antes do procedimento, de forma aleatória, um colírio em cada olho dos pacientes avaliados. A análise subjetiva da hiperemia conjuntival e do sangramento perioperatório foi realizada de forma duplo-cega, por dois cirurgiões. A avaliação objetiva do nível de hiperemia conjuntival foi realizada por análise das imagens obtidas por meio do software ImageJ®. Resultados: A análise de modelos multivariados de efeito misto indicou diferenças estatisticamente significantes entre os grupos em relação à hiperemia (avaliador 2) e ao sangramento intraoperatório (avaliadores 1 e 2), com maiores escores nos casos tratados com colírio de nafazolina + feniramina. Entretanto, não houve diferença estatística na análise objetiva realizada por meio da saturação de cores obtidas pelo programa ImageJ®. Conclusão: O colírio de brimonidina pode ser superior ao colírio de nafazolina + feniramina na redução do sangramento, levando-se em conta apenas a análise subjetiva.


ABSTRACT Objective: To evaluate the effect of 0.2% brimonidine eye drops in reducing hyperemia and ocular bleeding during strabismus surgeries, in comparison with 0.025% naphazoline + 0.3% pheniramine eye drops. Methods: Fourteen patients with strabismus and indication for bilateral surgical correction were evaluated. Before the procedure, the eye drops were instilled randomly in each eye of the evaluated patients. The subjective analysis of conjunctival hyperemia and perioperative bleeding was performed in a double-blind manner, by 02 surgeons. The objective assessment of the level of conjunctival hyperemia was performed by analyzing the images obtained using the ImageJ® software. Results: The analysis of multivariate mixed effect models indicated statistically significant differences between the groups in relation to hyperemia (rater 2) and intraoperative bleeding (raters 1 and 2) with higher scores in cases treated with naphazoline + pheniramine eye drops. However, there were no statistically significant differences in the objective analysis of color saturation obtained by the ImageJ® program. Conclusion: Brimonidine eye drops may be superior to naphazoline + pheniramine eye drops in reducing bleeding, taking into account the subjective analysis only.

RESUMO

Subconjunctival hemorrhage (SCH) is a benign eye condition that is often noticeable and leads to medical attention. Despite previous studies investigating the relationship between SCH and cardiovascular diseases, the relationship between SCH and bleeding disorders remains controversial. In order to gain further insight into this association, a nationwide cohort study was conducted using data from the National Health Insurance Service-National Sample Cohort version 2.0 from 2006 to 2015. The study defined SCH using a diagnostic code and compared the incidence and risk factors of intracerebral hemorrhage (ICH) and gastrointestinal (GI) bleeding in 36,772 SCH individuals and 147,088 propensity score (PS)-matched controls without SCH. The results showed that SCH was associated with a lower risk of ICH (HR = 0.76, 95% CI = 0.622-0.894, p = 0.002) and GI bleeding (HR = 0.816, 95% CI = 0.690-0.965, p = 0.018) when compared to the PS-matched control group. This reduced risk was more pronounced in females and in the older age group (≥ 50 years), but not observed in males or younger age groups. In conclusion, SCH dose not increase the risk of ICH and major GI bleeding and is associated with a decreased incidence in females and individuals aged ≥ 50 years.

RESUMO

OBJECTIVE: Subconjunctival hemorrhage (SCH) is a common presentation in patients with orbital trauma and often warrants investigation of underlying ocular pathology. Our study aims to assess the significance of SCH severity, graded in a spatial 0-360° manner, as a predictor for ocular pathology in patients with orbital fracture. DESIGN: Retrospective chart review. PARTICIPANTS: Patients with fractured orbits (n = 265) presenting to a level 1 trauma centre between August 2015 and January 2018. METHODS: Key elements of ophthalmic assessment, including visual acuity, SCH (0-360°), anterior- and posterior-segment examination, Hertel exophthalmometry, and ocular pathology, were recorded. Simple logistic regression assessed for association between SCH severity and ocular pathology. Odds ratios (ORs) were calculated with 95% CI. RESULTS: Among the 265 fractured orbits, 158 (59.6%) presented with no SCH, and 107 (40.4%) had some degree of SCH. Ocular pathology was noted in 24 fractured orbits (9%). Most common pathologies included entrapment (22.2%), hyphema (16.7%), traumatic optic neuropathy (8.3%), and commotio retinae (8.3%). Simple logistic regression revealed a higher incidence of ocular pathology with increasing severity of SCH from 0-360° (OR = 1.004; 95% CI 1.001-1.007; p = 0.0085). In addition, χ2 analysis demonstrated a higher proportion of ocular pathology in 181-270° (25.0%; p = 0.0466) and 271-360° SCH subgroups (26.3%; p = 0.0031) compared with the 0° SCH subgroup (6.3%). CONCLUSIONS: Our findings suggest that there is some correlation between the extent of SCH and ocular pathology. However, patient care and investigations should continue to be directed by a full clinical assessment of patients with orbital trauma.

RESUMO

Subconjunctival hemorrhages commonly present to eye care professionals and are frequently regarded as benign self-limited conditions. In selected cases, subconjunctival hemorrhages can be a harbinger of more severe disease. Perivascular epithelioid cell tumors, or PEComas, are rare mesenchymal neoplasms believed to originate from perivascular myoid cells and are rarely present in ocular structures. We present a rare case of a conjunctival perivascular epithelioid cell tumor that initially presented with recurrent subconjunctival hemorrhage. To our knowledge, this is the first description of a PEComa with a RBM10-TFE3 gene fusion, only previously seen with renal cell carcinoma. Physicians should be aware of this rare condition, its location in the fornix and its presentation as a recurrent subconjunctival hemorrhage.

RESUMO

A descorna cirúrgica a campo ainda e uma prática comum em animais de produção, apesar deste procedimento na maioria ainda se realizado por leigos, ou realizada em animais com menos de um ano de idade com ferro candente (avermelhado), esta conduta geralmente é efetuada na propriedade, sendo executada pelo próprio proprietário ou funcionário. O presente experimento usando anestesia geral e bloqueio local do nervo córneo e circularmente na base do corno com abraçadeira de naylon para sutura de pele, associada a ligadura da artéria e veia cornual mostrou ser eficiente reduzindo o tempo cirúrgico a campo e promovendo uma prevenção antecipada de hemorragia que é frequente para este procedimento.(AU)


The surgical dehorning the field and still a common practice in farm animals, although this procedure in most still held by lay people, or performed on animals less than one year old with red-hot iron (red), this conduct is usually done on the property, being executed by the owner himself or employee. This experiment using general anesthesia and local lock of corneal nerve and round the horn base with clamp naylon for skin suture, associated with ligature of the artery and vein cornual is efficient by reducing surgical time field and promoting an early prevention of bleeding is frequent for this procedure.(AU)

RESUMO

BACKGROUND: Severe intraocular hemorrhage is a rare complication of cataract surgery due to the recent generalization of minimal-incision cataract surgery. We report a case of a massive intraocular hemorrhage that probably originated from the central retinal artery after cataract surgery, in which hemostasis was difficult to achieve during vitrectomy. CASE PRESENTATION: An 86-year-old woman was referred to our department for intraocular lens (IOL) dislocation after undergoing cataract surgery. Massive intraocular hemorrhage was observed during the initial visit to our department. She underwent pars plana vitrectomy (PPV) and IOL repositioning under local anesthesia. However, the hemorrhage could not be removed completely because of continued massive intraoperative bleeding from the posterior fundus, and it was extremely difficult to achieve hemostasis during the initial surgery. At 7 days after the initial surgery, PPVs were performed under general anesthesia. Bleeding significantly decreased in the second surgery compared to the first. The bleeding probably originated from the central retinal artery on the optic disc; hemostasis was obtained by coagulation of the bleeding site with intraocular diathermy. After the second surgery, there was no exacerbation of bleeding and the patient's condition was stable. However, the patient's visual acuity showed no light perception after the second surgery. CONCLUSIONS: Massive intraocular hemorrhage may occur from the central retinal artery after undergoing cataract surgery. In such cases, surgery with general anesthesia with a lower maintained blood pressure (instead of surgery under local anesthesia) should be recommended, considering the possibility of difficult hemostasis in the event of bleeding from the retinal artery.

RESUMO

Background: Expulsive suprachoroidal hemorrhage is a rare but dreadful complication of any ophthalmic surgery. Hence an ophthalmologist should know about the various risk factors, methods for preventing such a situation, and be aware of the various options for timely management to tackle the situation. Purpose: To discuss the risk factors, intraoperative signs, and ways of managing expulsive choroidal hemorrhage. Synopsis: We discuss two cases having multiple risk factors, where the patients underwent tectonic penetrating keratoplasty. In view of extensive involvement of ocular structures, the patients were clearly explained about the guarded visual prognosis and the risk of auto-evisceration. Following trephination of host cornea, rise in intraocular pressure was identified by the increasing size of the vitreous seen prolapsing through the wound and markedly visible pulsations, along with subconjunctival bleeding. Suprachoroidal hemorrhage was suspected and immediate tamponade was given. However, bleeding was not controlled, and eventually, expulsion of all the intraocular contents occurred. Highlights: A surgeon must be aware of the risk factors, be prompt to identify the signs, and must take immediate actions for the management of expulsive choroidal hemorrhage, a rare but dreadful complication of intraocular procedures.

RESUMO

A previously healthy man in his 20s presented with acute respiratory distress syndrome and subconjunctival haemorrhage. Imaging was indicative of pervasive pulmonary haemorrhage. There was no evidence of renal involvement. The patient rapidly deteriorated with aggravating respiratory failure regardless of invasive mechanical ventilation and required extracorporeal membrane oxygenation (ECMO). This maintained the patient adequate time to allow aggressive therapy. Skin biopsy indicated leucocytoclastic vasculitis. Given that the patient was C-antinuclear cytoplasmic autoantibody (ANCA) positive, pulse dose steroids and rituximab were initiated for the suspicion of ANCA-associated vasculitis (AAV) which resulted in improvement of airspace disease and subconjunctival haemorrhage. Only a few cases reported successful use of ECMO in severe diffuse alveolar haemorrhage (DAH) due to AAV, but no case was in DAH combined with subconjunctival haemorrhage. The need for systemic anticoagulation with pre-existing haemorrhage is still a challenging dilemma.

RESUMO

OBJECTIVE: Subconjunctival hemorrhage (SCH) is a reported sign of occult abusive injury, but there are limited published data about SCH during childhood. We sought to determine the prevalence and causes of SCH in children. METHODS: This is a retrospective cross-sectional study of children seen by pediatric ophthalmologists in an outpatient setting over 4 years. Primary outcomes were prevalence and causes of SCH, based on history, physical ocular and nonocular findings, and laboratory and imaging studies. Subconjunctival hemorrhage prevalence was determined including and excluding eye surgery to reduce bias in the prevalence estimate. RESULTS: We studied 33,990 children, who underwent 86,277 examinations (median age, 5 years; range, 2 days to 18 years; 9282 younger than 2 years, 13,447 age 2-7 years, 11,261 age 8-18 years). There were 949 cases of SCH (1.1%; 95% confidence interval, 1.0-1.2). When surgery was excluded, there were 313 cases (prevalence, 0.4%; 95% confidence interval, 0.3-0.4), of which 261 (83%) were due to trauma; 40 (13%) ocular surface inflammation, including infectious conjunctivitis; 7 (2%) orbital or conjunctival lesion; 3 (1%) vessel rupture from choking or cough; and 2 (1%) coagulopathy related. Across all ages, including less than 2 years, trauma and inflammation together accounted for 94% to 97% of all cases of SCH. CONCLUSIONS: Subconjunctival hemorrhage is uncommon in children. The great majority of cases are due to trauma. All children with SCH, including infants and young children, should be closely examined to identify other ocular or nonocular signs of trauma.

RESUMO

PURPOSE: To evaluate the efficacy of preoperative topical brimonidine use to maintain visibility during trabeculectomy and control intraoperative bleeding and postoperative subconjunctival hemorrhage. METHODS: The first group comprised 35 eyes of 34 patients administered brimonidine tartrate 0.15% (Brimogut, Bilim Ilac, Turkey) eye drops 6 and 3 min before surgery, and 33 eyes of 31 patients who received no medication for vasoconstriction formed the second group. Preoperative and postoperative photographs and operation video images were taken and vision analysis software used. Black-and-white images were obtained to identify the blood vessel and surface hemorrhage areas. The surface area of the hemorrhage was calculated by counting the black pixels with Image J software. RESULTS: There was no significant difference between two groups in terms of baseline (preoperative) eye redness (p > 0.05). In the first group, the eye redness values were 344.7 ± 19.5 pixels preoperatively and 244.1 ± 23.3 pixels at the beginning of the surgery, respectively (p < 0.001). However, no significant change was observed in the second group in eye redness (348.2 ± 17.5 pixels preoperatively and 360.7 ± 26.8 pixels at the beginning of the surgery, p > 0.05). Cautery was used for an average of 11.91 ± 1.96 s in the first group and 25.57 ± 4.66 s in the second to control intraoperative bleeding (P < 0.001). CONCLUSION: Preoperative topical brimonidine use in trabeculectomy surgery significantly decreased intraoperative bleeding and postoperative subconjunctival hemorrhage and facilitated bleeding control.
