Conjunctival Perivascular Epithelioid Cell Neoplasm With RBM10-TFE3 Fusion Presenting as Recurrent Subconjunctival Hemorrhage.

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.

Significance of subconjunctival hemorrhage in predicting ocular pathology for patients with orbital fracture.

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.

A Recurrent Orbital Hemorrhage in an Older Adult.

An adult patient in their 70s presented with unilateral painless proptosis and blurred vision of the right eye that resolved with corticosteroid treatment. Magnetic resonance imaging revealed a retrobulbar hemorrhage. Six months later, the hemorrhage and proptosis recurred, with incomplete resolution despite similar treatment. What would you do?

A rare ophthalmic complication: Expulsive suprachoroidal hemorrhage.

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.

Prevalence and Causes of Subconjunctival Hemorrhage in Children.

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.

Risk Factors for Severe Bleeding Complications in Vitreoretinal Surgery and the Role of Antiplatelet or Anticoagulant Agents.

PURPOSE: To evaluate the influences and risk factors for severe bleeding complications during vitreoretinal surgery and to investigate the role of antiplatelet and anticoagulant agents. DESIGN: Prospective trial. PARTICIPANTS: Patients undergoing vitreoretinal surgery. METHODS: The procedures included were pars plana vitrectomy and scleral buckling. We developed a uniform classification to grade the bleeding severity. Bleeding was graded on an ordinal scale ranging from 0 to 5. Immediately after surgery and 1 day later, the incidence and the severity of bleeding events was documented on a standardized form. A grade of 3 or more was defined as severe bleeding. Furthermore, the influence of known systemic disorders before surgery, the type of anesthesia, type of surgical procedure, intraoperative blood pressure, and the use or change of antiplatelet or anticoagulant agents on intraoperative bleeding was analyzed. MAIN OUTCOME MEASURES: Incidence and risk factors for severe intraoperative bleeding events. RESULTS: Data from 374 eyes undergoing vitreoretinal procedures were included in our study (mean age, 67.6 ± 12.9 years). A severe intraoperative bleeding event was observed in 15 eyes (4%). We found that concomitant diseases such as diabetes mellitus and carotid artery stenosis, the presence of diabetic retinopathy, younger age, and scleral buckling combined with a transscleral puncture were associated significantly with severe bleeding events. By contrast, use of antiplatelet or anticoagulant agents, or both, had no significant influence on severe intraoperative bleeding events. CONCLUSIONS: Although external manipulations during buckling surgery (e.g., drainage of subretinal fluid) and concomitant diseases such as diabetes mellitus and carotid artery stenosis influences the risk of severe intraoperative bleeding events, we did not detect an increased risk related to coexisting antiplatelet or anticoagulant medication use, or both.

Tears of blood - a female adolescent with essential idiopathic bilateral haemolacria: case report and brief review.

Haemolacria is a rare condition that usually occurs secondary to a hidden pathology. On rare occasions when no underlying cause may be found, it is called essential idiopathic haemolacria. Here the authors report a case of a 13-year-old girl presented to the ophthalmology emergency department with spontaneous bloody tears from both eyes for the past six months. There was associated bleeding from the ear. The rest of the systemic and ophthalmology examinations were within normal limits. She was investigated systemically to look for any underlying pathology; however, her blood investigations, radiological imaging and local examinations performed by the Otorhinolaryngology, Ophthalmology, Gynaecology and Internal Medicine departments were all normal. A final diagnosis of bilateral essential haemolacria was made.

Retrolental Hemorrhage in Berger's Space After Intravitreal Bevacizumab Injection for Retinopathy of Prematurity.

The authors report a rare case of successful self-resolution and discuss the need for proper injection technique to prevent this complication. [J Pediatr Ophthalmol Strabismus. 2020;57:e71-e73.].

Spontaneous orbital haematoma in a scurvy child: A forgotten diagnosis.

Spontaneous unilateral orbital haematoma in children is not common and very rarely caused by scurvy. Scurvy is a clinical syndrome with a spectrum of clinical manifestations due to severe prolonged vitamin C deficiency leading to impairment of collagen synthesis over skin, bone, teeth and blood vessels. This paper presents a unique case of a 7- year-old girl with learning difficulty who presented with spontaneous right proptosis due to scurvy. Imaging studies suggestive of intra- orbital extraconal haemorrhage. The child was treated with a higher than recommended dose of vitamin C initially in emergency situation. She responded well and discharged without complication. Spontaneous orbital haematoma due to scurvy is very rare with less than 10 cases published in literature. The present case should raise the awareness regarding this forgotten disease and importance of balance nutrition amongst children.

Intraocular endoscopy for the evaluation and treatment of hypotony due to a traumatic cyclodialysis: a case report.

BACKGROUND: A cyclodialysis cleft often leads to direct communication between the anterior chamber and the suprachoroidal space. It is a rare condition that is encountered with blunt trauma, and less commonly, after surgery. Hypotony is the major sequelae that may lead to hypotonous maculopathy, optic disc edema, corneal folds, and astigmatism. These may cumulatively lead to visual loss. We describe how endoscopy in a cyclodialysis repair allowed us to accurately locate the cleft and guided its appropriate management avoiding unnecessary cryopexy. CASE PRESENTATION: A 41-year-old male experienced a traumatic cyclodialysis cleft, which resulted in persistent hypotony. Pars plana vitrectomy was performed to treat vitreous hemorrhage. Scleral indentation was attempted to visualize the cyclodialysis cleft. However, the depression distorted the visualization. Intraocular endoscopy was therefore used to evaluate the cleft. Guided by this assessment, only intraocular gas tamponade was used to reposition the ciliary body. The patient's intraocular pressure was restored to 13 mmHg 3 days after the operation, and OCT confirmed cleft closure 1 month after the operation. CONCLUSION: Endoscopy-assisted repair of cyclodialysis is an approach that enhances visualization and can guard against common causes of persistent cleft and hypotony, as well as reveal the causes of recurrent failure. Hence, it can eliminate unnecessary cryopexy that might worsen the hypotonous state. In our case, intraocular endoscopy was effective for the evaluation of a cyclodialysis cleft and the subsequent selection of an appropriate management technique, gas tamponade, that was more conservative than other approaches initially considered.

[Retrospective investigation of spontaneous bloody tears: a report of 27 cases].

Objective: To summarize clinical experience on the clinical feature, etiology and treatment of patients with spontaneous bloody tears as the initial symptom. Methods: Retrospective series of case studies. The clinical data and follow-up data of 27 cases of bloody tears as the first symptom in Lacrimal Center of Ophthalmology, the Third Medical Center of Chinese PLA General Hospital from June 2015 to December 2018 were reviewed. The clinical feature, specific cause, diagnosis, treatment and prognosis of these cases were evaluated. Results: A total of 27 cases were collected in this study. The patients were 10 males (37.0%) and 17 females (63.0%), including 21 adults (≥ 18 years old, 77.8%) and 6 minors (<18 years old, 22.2%). There were 22 monocular cases (81.5%) and 5 binocular cases (18.5%). Five cases (18.5%) were bleeding from the eye and other parts of the body, and 22 cases (81.5%) were bleeding only from the eye. There were 19 cases (70.4%) with hematic epiphora and secretions from the punctum, 3 cases (11.1%) with blood-stained tears, and 7 cases (25.9%) with blood-like tears. With regard to etiology, 6 cases (22.2%) were combined with systemic lesions, one of which was granulomatosis with polyangiitis and five of which (<18 years old) were idiopathic bloody tears. Twenty-one cases (77.8%) were local lesions, including 18 cases only involving the lacrimal system, 2 cases only involving the ocular surface, and 1 case involving both the lacrimal system and the ocular surface. Among the 21 cases with local lesions, 5 cases were induced by foreign body, 6 cases were induced by simple inflammation, and 10 cases were induced by tumor including 1 case with conjunctival benign tumor and 9 cases with tumor of the lacrimal system (5 with malignant tumor and 4 with benign tumor). Patients with idiopathic bloody tears received psychological and medical treatment, and interictal discharge was lengthened. One case of granulomatosis with polyangiitis was treated by trans-nasal endoscopic dacryocystorhinostomy. With the recurrence of granulomatosis and polyangiitis, bloody tears recurred after surgery. One patient with conjunctival hemangioma was untreated. Lesions in the lacrimal duct system were removed and dacryocystorhinostomy was performed. In this study, 2 patients (1 with small cell neuroendocrine carcinoma and 1 with adenoid cystic adenocarcinoma) died and the other had a good prognosis. Conclusions: Among the cases of bloody tears, adults and local lesions are more common. Most of the lesions are located in the lacrimal system and are tumors. The main treatment is to remove the lesions, and if necessary, to expand the resection and reconstruct the lacrimal duct. Idiopathic bloody tears occur in minors, who are gave psychotherapy and necessary medical treatment. (Chin J Ophthalmol, 2020, 56: 53-58).

Congenital corneal blood staining secondary to hemorrhagic persistent fetal vasculature.

An African American girl born at 37 weeks via spontaneous vaginal delivery to a 33-year-old woman was noted on delivery to have a unilateral absent red reflex in the right eye, which was enlarged. Intraocular pressure was elevated, and the cornea had a straw-colored opacity. B-scan ultrasonography of the right eye showed diffuse hyperechoic vitreous opacities and a retrolental mass, with a hyperechoic band stretching from the optic disk to the posterior lens. Neuroimaging showed a unilateral enlarged globe, intraocular hemorrhage, and persistent fetal vasculature, with no other intracranial pathology. An anterior chamber washout revealed liquified blood; the presence of corneal blood staining was confirmed. A spontaneous intraocular hemorrhage associated with persistent fetal vasculature was suspected, leading to secondary glaucoma and corneal blood staining.
