Juvenile xantogranuloma with íris involvement / Xantogranuloma juvenil com acometimento iriano

Abstract Herein we report a case of juvenile xantogranuloma, an inflammatory disease more commonly diagnosed during childhood and is characterized by cutaneous and ocular manifestations. Iris is the main target, presenting as local or diffuse yellowish lesions. Iris involvement may precipitate not only glaucoma but also amblyopia. Treatment is based on corticosteroids therapy, either local or systemic aiming disease control.

Resumo É relatado um caso raro de xantogranuloma juvenil, doença de natureza inflamatória diagnosticada mais frequentemente na infância, com manifestações cutâneas e oculares. A íris é o principal sítio extracutâneo da doença, apresentando-se como lesão amarelada, difusa ou localizada. O acometimento iriano pode acarretar surgimento de glaucoma, além de ambliopia. O manejo clínico da lesão ocular no presente caso foi baseado no necessidade no uso contínuo de corticoide tópico e sistêmico para estabilização da doença.

Hipema traumático en paciente con hemoglobinopatía / Trauma hyphema in a patient with hemoglobinopathy

El hipema traumático es la presencia de sangre en la cámara anterior y puede presentarse en traumas oculares a globo abierto o cerrado, así como coexistir con otras lesiones. Se presenta un paciente masculino de 52 años de edad, coloración de la piel negra, quien sufrió un trauma contuso del ojo derecho que le provocó hipema y requirió ingreso hospitalario. A pesar del tratamiento médico convencional, evolucionó desfavorablemente, ya que presentó resangrado tardío. motivados por esto le indicamos un estudio de electroforesis de hemoglobina e incorporamos un tratamiento sistémico con antifibrinolíticos. Se obtuvo resolución de la hemorragia en las primeras 48 horas de iniciar el tratamiento. Se concluye que el uso de antifibrinolíticos resulta efectivo para el tratamiento del hipema postraumático en pacientes con hemoglobinopatías(AU)

Trauma hyphema is the presence of blood in the anterior chamber and may occur in open or closed eyeball traumas as well as coexist in other lesions. This is the case of a Black male patient aged 52 years, who suffered a blunt trauma in his right eye causing hyphema and requiring hospitalization. Despite the conventional medical treatment, the recovery was unfavorable since he presented with late rebleeding. Due to the above-mentioned condition, he was performed a hemoglobin electrophoresis study and he received a systemic treatment with antifibrinolytics. Hemorrhage disappeared after 48 hours of treatment. It was concluded that the use of antifibrinolytics is effective for the treatment of post-trauma hyphema in patients with hemoglobinopathy. Key words: Hyphema; antifibrinolytics; hemoglobinopathy(AU)

The Incidence and Risk Factors for Ocular Hypertension in Traumatic Hyphema

PURPOSE: To evaluate the incidence and risk factors for ocular hypertension (OHT) in traumatic hyphema within 7 days after trauma. METHODS: A retrospective case series study of 265 traumatic hyphema inpatients from 2010–2016. OHT was defined as intraocular pressure (IOP) that exceeded 21 mmHg using two consecutive measurements by a Goldmann applanation tonometer within 7 days after trauma. The subjects were divided into two groups (OHT group and non-OHT group). Age, sex, best-corrected visual acuity (BCVA), IOP, hyphema grade, presence of systemic disease, and past history of glaucoma were compared between the two groups. RESULTS: Of the 265 patients, 95 (35.8%) developed OHT after traumatic hyphema. Of those 95 patients, 70 (73.7%) developed OHT within 1 day after trauma; 18 (18.9%) developed OHT 2–3 days after trauma; and 7 (7.4%) developed OHT 4–7 days after trauma. Compared to the non-OHT group, the OHT group had a lower visual acuity (p = 0.018) and higher IOP (p < 0.001). In addition. if the hyphema grade was higher the incidence of OHT was significantly higher (p = 0.017). Using multivariate logistic regression analysis, the BCVA (p = 0.045) and hyphema grade (p = 0.006) were associated with the incidence of OHT in traumatic hyphema within 7 days after trauma. CONCLUSIONS: The incidence of OHT in traumatic hyphema within 7 days after trauma was 35.8%. The BCVA and hyphema grade were associated with the incidence of OHT within 7 days after trauma.

Clinical Characteristics of Retinoblastoma Patients whose Diagnosis was Difficult due to Atypical Ocular Manifestation

PURPOSE: To report the clinical characteristics of retinoblastoma patients whose diagnosis was difficult due to atypical ocular manifestations. METHODS: Among retinoblastoma patients who were diagnosed and treated from January 1999 to December 2014 at Seoul National University Children's Hospital, 6 patients whose diagnosis was difficult were retrospectively reviewed. Factors including age, sex, family history, initial findings, time to final diagnosis, histopathologic examination, additional treatment, and survival rate were evaluated. RESULTS: Among 6 patients, 5 were male, and the mean age at the initial visit was 32.9 ± 19.1 months. None of the patients had family history, and all presented with unilateral lesion at the initial visit. The initial diagnoses were Coats' disease and uveitis in 2 patients, respectively, and persistent hyperplastic primary vitreous and traumatic hyphema in 1 patient, respectively. During an intensive short-term follow-up of 8.3 ± 5.3 weeks, 2 patients showed malignant cells after external subretinal fluid drainage procedure, and 4 patients demonstrated increasing ocular size or calcification in imaging. These patients received enucleation under suspicion of malignancy and were finally diagnosed with retinoblastoma after histopathologic examination. There were 2 patients with optic nerve involvement, and 3 patients underwent additional systemic chemotherapy. Five patients were followed-up for 7.6 ± 6.3 years after enucleation, and the mean age at final follow-up was 10.6 ± 7.4 years. CONCLUSIONS: Retinoblastoma is one of the diseases in which early diagnosis and treatment are important. However, some cases are difficult to diagnose, even for experienced clinicians. If there are no typical manifestations such as mass or calcification and early findings show retinal detachment, glaucoma, pseudohypopyon, or hyphema, intensive short-term follow-up to exclude retinoblastoma is needed.

A Case of Hyphema after Selective Laser Trabeculoplasty

PURPOSE: To report a case of hyphema after selective laser trabeculoplasty (SLT) in a patient with pseudoexfoliative glaucoma. CASE SUMMARY: A 77-year-old female was referred for elevation of intraocular pressure (IOP). Previously, she had been diagnosed with pseudoexfoliative glaucoma in the right eye and was using topical IOP-lowering agents. The best corrected visual acuity was 20/100 in the right eye and 20/40 in the left eye. IOP, measured with Goldmann applanation tonometer, was 32 mm Hg in the right eye and 20 mm Hg in the left eye. Gonioscopy revealed open-angle glaucoma with +2 trabecular meshwork pigmentation but without peripheral anterior synechiae or neovascularization. SLT was performed in the right eye. Two days later, the patient had sudden onset of blurred vision and pain in the right eye. Visual acuity was limited to light perception, and IOP was 34 mm Hg in the right eye. Slit-lamp examination revealed 1.1 mm hyphema with 4+ red blood cell count in the anterior chamber. Three weeks after the SLT, hyphema in the right eye disappeared, but IOP was measured to be 42 mm Hg. The patient underwent trabeculectomy in the right eye. CONCLUSIONS: SLT is an effective means of lowering IOP with low risk of complications. However, hyphema can rarely occur after SLT and can affect the outcome of the treatment.

Red eyes in the necropsy floor: twenty cases of hyphema in dogs and cats / Olhos vermelhos na sala de necropsia: vinte casos de hifema em cães e gatos

Hyphema (hemorrhage within the anterior chamber of the eye) can be caused by several mechanisms and can easily be detected in routine ophthalmic or necroscopic examination as discolored red eye(s). The purpose of this study is to report the cause of hyphema diagnosed as a postmortem finding in dogs and cats. Twenty cases, 14 dogs and six cats of several ages and breeds and of both sexes were included in the study. Hyphema presented as a unilateral (14 cases out of 20) or bilateral (6/20) disorder in dogs and cats and extension of hemorrhage varied from minimal to diffuse. Hyphema was secondary to systemic disease (15/20) or occurred as a primary ocular lesion (5/20) in four dogs and one cat. Primary hyphema was always unilateral. In four of these cases, the cause of hyphema was trauma and remaining case was caused by phacoclastic uveitis in a dog with bilateral hypermature cataract. Various causes of bleeding disorders were found related to secondary hyphema: in decreasing order of frequency, they included vasculitis (8/15), systemic hypertension (5/15), and acquired coagulopathies (2/15). Vasculitis due to feline infectious peritonitis accounted for half of the cases (n=3) of systemic hyphema in cats. The various pathological aspects and pathogenesis of hyphema in dogs and cats are described and discussed...

Hifema, hemorragia na câmara anterior do olho, pode ser causada por vários mecanismos e pode facilmente ser detectada no exame oftálmico de rotina ou na necropsia como olho(s) vermelhos(s). O objetivo deste trabalho é relatar as causas de hifema diagnosticado como um achado postmortem em cães e gatos. Vinte casos, 14 cães e seis gatos de várias idades e raças, e de ambos os sexos foram incluídos no estudo. O hifema em cães e gatos teve uma apresentação unilateral (14 casos dos 20) ou bilateral (6/20), e a extensão da hemorragia variou de mínima a difusa. O hifema era secundário à doença sistêmica (15/20) ou ocorreu como lesão ocular primária em cinco dos 20 casos (quatro cães e um gato). O hifema primário foi sempre unilateral; em quatro desses casos, a causa foi traumatismo e o caso restante foi causado por uveíte facoclástica em um cão com catarata hipermadura bilateral. Várias causas de distúrbios hemorrágicos foram encontradas em relação ao hifema secundário: em ordem decrescente de frequência foram: vasculite (8/15), hipertensão sistêmica (5/15) e coagulopatias adquiridas (2/15). Os vários aspectos patológicos e a patogênese do hifema são descritos e discutidos...

A Case of Cyclodialysis Cleft with Hypotony during Ahmed Valve Implantation Surgery

PURPOSE: To report a case of cyclodialysis cleft with hypotony during Ahmed valve implantation. CASE SUMMARY: A 47-year-old male was referred for uncontrolled intraocular pressure (IOP) in the right eye. The patient had a history of ocular trauma and traumatic hyphema. He underwent pars plana vitrectomy, phacoemulsification and intraocular lens implantation 1 month prior due to rhegmatogenous retinal detachment. At the end of the Ahmed valve implantation surgery, the eye was hypotonic despite a deep anterior chamber. The hypotony continued and choroidal effusion developed. Anterior segment optical coherence tomography and gonioscopic examinations revealed small cyclodialysis clefts. After medical treatment with cycloplegics and steroids, choroidal effusion disappeared and IOP was normalized. CONCLUSIONS: Patients with previous ocular trauma or surgery could be prone to developing cyclodialysis cleft with hypotony. Inadvertent cyclodialysis cleft with hypotony can be treated with cycloplegics and steroids.

The Effect of Intravitreal Bevacizumab Injection before Trabeculectomy in Patients with Neovascular Glaucoma

PURPOSE: To evaluate the efficacy of preoperative intravitreal bevacizumab injection (IVBI) and prognostic factors of surgical success in neovascular glaucoma patients, who underwent trabeculectomy. METHODS: A total of 58 patients (58 eyes) diagnosed with neovascular glaucoma who underwent trabeculectomy between 2003 and 2013 were enrolled in this retrospective study. Trabeculectomy with mitomycin C was performed between 2003 and 2006 and additional preoperative IVBI with the above mentioned technique was performed between 2007 and 2013. To evaluate the efficacy of preoperative IVBI, the patients were divided into the preoperative IVBI group and control group. Best corrected visual acuity (BCVA) and intraocular pressure (IOP) were measured from preoperative to postoperative 12 months. To evaluate the prognostic factors related to surgical success, the following was investigated: age, lens status, preoperative IVBI, time interval between preoperative IVBI and trabeculectomy, previous vitrectomy and, postoperative complications. RESULTS: Trabeculectomy with mitomycin C only was performed in 26 eyes and additional preoperative IVBI was performed in 32 eyes. Surgical success was 81.3% in the IVBI group and 57.7% in the control group at postoperative 6 months (p = 0.012), and 78.1% in the IVBI group and 50.0% in the control group at postoperative 12 months (p = 0.021). Statistically significant IOP reduction effect was observed in the IVBI group (p = 0.048), and reduced anti-glaucoma eye drop usage was observed in the IVBI group (0.4) compared with 0.8 in the control group (p = 0.040). Postoperative hyphema (hazard ratio [HR] = 2.872, p = 0.044) and preoperative IVBI (HR = 0.280, p = 0.030) were considered risk factors for surgical failure in univariate analysis, however, only preoperative IVBI was statistically significant in multivariate analysis (p = 0.046). CONCLUSIONS: In neovascular glaucoma patients, preoperative IVBI before trabeculectomy is a good prognostic factor of surgical success and shows benefit in lowering the IOP and reducing anti-glaucoma eye drop usage at postoperative 1 year.

Combined Phacoemulsification, Synechiolysis without Gonioprism Lens and Intracameral Tissue Plasminogen Activator Injection for Angle-Closure Glaucoma

PURPOSE: In this study we evaluated the safety and efficacy of combined phacoemulsification and synechiolysis without aid of gonioprism lens and intraoperative intracameral tissue plasminogen activator (tPA) injection for angle-closure glaucoma. METHODS: The method used in this study was synechiolysis with Kuglen hook without aid of gonioprism lens and intraoperative intracameral tPA injection following cataract surgery. RESULTS: A total of 20 patients with a mean age of 71.4 +/- 5.4 years were treated. Mean follow-up time was 31.3 +/- 24.3 months. Mean preoperative and last visit intraocular pressures (IOPs) were 21.70 +/- 9.50 mm Hg and 12.40 +/- 2.30 mm Hg, respectively (p < 0.0001). The mean number of glaucoma medications decreased from 2.40 to 0.30 (p < 0.0001). IOP was maintained below 16 mm Hg in all cases. No significant intraoperative and postoperative complications, hyphema, or fibrin reaction occurred. CONCLUSIONS: Combined phacoemulsification and peripheral anterior synechiolysis with Kuglen hook without aid of gonioprism lens and intraoperative intracameral tPA injection is an effective and safe surgical procedure.

Caracterización clinicoepidemiológica de pacientes con hifema por traumatismo ocular / Clinical and epidemiological characterization of patients with hyphema due to ocular traumatism

Se realizó un estudio descriptivo, retrospectivo y longitudinal de 34 pacientes con hifema ocasionado por trauma, ingresados en el Servicio de Oftalmología Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba, de enero a diciembre de 2013, con vistas a caracterizarles según algunas variables clinicoepidemiológicas. En la serie se observó un predominio del sexo masculino (64,7 %) y el grupo etario de 40-49 años (32,4 %); en tanto, el hifema de grado I fue el más representativo clínicamente (41,2 %), producido por traumas contusos en la mayoría de los afectados (76,5 %), y las complicaciones más frecuentes fueron la hipertensión ocular (23,5 %) y la uveítis (17,6 %). No obstante, el tratamiento adecuado y oportuno permitió que el mayor porcentaje de los pacientes mejoraran la agudeza visual.

A descriptive, retrospective and longitudinal study of 34 patients with hyphema caused by trauma, admitted in the Ophthalmology Service of "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba was carried out from January to December, 2013, aimed at characterizing them according to some clinical and epidemiological variables. A prevalence of the male sex was observed in the series (64.7%) and the age group 40-49 (32.4%); while, the degree I hyphema was clinically the most representative (41.2%), caused by contusion traumas in most of the affected ones (76.5%), and the most frequent complications were the ocular hypertension (23.5%) and uveitis (17.6%). However, the appropriate and opportune treatment allowed that the highest percentage of the patients improved the visual acuity.

Delayed-Onset Interface Fluid Syndrome after LASIK Surgery in Traumatic Hyphema

A 50-year-old female was referred to our clinic with visual disturbance, hyphema and increased intraocular pressure (IOP) in her right eye 7 days after experiencing blunt trauma in that eye. She had undergone uncomplicated laser in situ keratomileusis (LASIK) on both eyes 10 years earlier. At initial examination, the best corrected visual acuity (BCVA) in her right eye was counting fingers at 2 feet with no correction. Central Goldmann applanation tonometry (GAT) showed an IOP of 7 mm Hg. Peripheral digital tonometry showed the IOPs in her right eye superiorly, nasally, temporally, and inferiorly were 36 mm Hg, 35 mm Hg, 34.5 mm Hg and 36.5 mm Hg, respectively. Slit-lamp examination showed diffuse epithelial and stromal edema and a blood clot 1 mm in height in the anterior chamber. Spectral domain scanning laser ophthalmoscope/optical coherence tomography (SD-SLO/OCT) images showed a pocket of fluid between the LASIK flap and the underlying stroma. The patient was started on anti-inflammatory agent and IOP lowering agents. After 15 days of treatment, IOP measured with GAT was 10 mm Hg, slit-lamp examination showed that epithelial and stromal edema had disappeared, and OCT showed no fluid between the corneal flap and stroma.

A Case of Complete Recovery of Isolated Neurogenic Ptosis after Trauma

PURPOSE: To report a rare case of isolated neurogenic blepharoptosis secondary to eyelid trauma. CASE SUMMARY: A previously healthy 41-year-old male was evaluated for decreased visual acuity and blepharoptosis in the left eye after ocular trauma. On ophthalmologic examination, visual acuity in the left eye was hand motion, intraocular pressure was 29 mm Hg, hematoma and eyelid edema were minimal. The patient had complete unilateral ptosis with superficial upper eyelid laceration. Additional findings in the left eye included fracture of the medial orbital wall, hyphema, iris sphincter muscle tear, iridodialysis and conjunctival laceration. The other examinations were unremarkable with full ocular motility. Because of iris sphincter muscle tear and iridodialysis, the pupillary reaction could not be evaluated. His left upper eyelid drooped completely and levator function test (LFT) was 0 mm. He was diagnosed with an isolated neurogenic blepharoptosis and received oral prednisolone at a dose of 1 mg/kg per day for 7 days with gradual tapering. One month later, the patient had normal symmetric lid height and completely restored levator function.

Review of cystic and solid tumors of the iris

Iris tumors are broadly classified into cystic or solid lesions. The cystic lesions arise from iris pigment epithelium [1PE] or iris stroma. IPE cysts classically remain stable without need for intervention. Iris stromal cyst, especially those in newborns, usually requires therapy of aspiration, possibly with alcohol-induced sclerosis, or surgical resection. The solid tumors included melanocytic and nonmelanocytic lesions. The melanocytic iris tumors include freckle, nevus [including melanocytoma], Lisch nodule, and melanoma. Information from a tertiary referral center revealed that transformation of suspicious iris nevus to melanoma occurred in 4% by 10 years and 11% by 20 years. Risk factors for transformation of iris nevus to melanoma can be remembered using the ABCDEF guide as follows: A=age young [<40 years], B=blood [hyphema] in anterior chamber, C=clock hour of mass inferiorly D=diffuse configuration, E=ectropion, F= eathery margins. The most powerful factors are diffuse growth pattern and hyphema. Tumor seeding into the anterior chamber angle and onto the iris stroma are also important. The nonmelanocytic iris tumors are relatively uncommon and included categories of choristomatous, vascular, fibrous, neural, myogenic, epithelial, xanthomatous, metastatic, lymphoid, leukemic, secondary, and non-neoplastic simulators. Overall, the most common diagnoses in a clinical series include nevus, IPE cyst, and melanoma. In summary, iris tumors comprise a wide spectrum including mostly iris nevus, IPE cyst, and iris melanoma. Risk factors estimating transformation of iris nevus to melanoma can be remembered by the ABCDEF guide

A Case of Bilateral Peripheral Ulcerative Keratitis in a Patient with Rheumatoid Arthritis after Cataract Extraction

PURPOSE: To report a case of bilateral peripheral ulcerative keratitis after cataract extraction with a clear corneal incision in a patient with rheumatoid arthritis. CASE SUMMARY: A 67-year-old woman was referred to our clinic with bilateral ocular pain and visual disturbances, 10 days after a cataract extraction in her right eye. The patient had undergone a cataract extraction with clear corneal incision in the left eye and the same procedure was performed in the right eye after 1 week. During the surgery, hyphema occurred because of the iris damage by the phacoemulsification tip. Slit lamp examination showed bilateral peripheral ulcerative keratitis around the incision site and diffused corneal edema. Topical instillation and systemic administration of antibiotic agents were given as treatment but the patient showed no improvement. Corneal culture and smear were performed and showed a negative result. Because the patient was previously diagnosed with rheumatoid arthritis and showed the characteristic finger deformity, she was diagnosed with a sterile peripheral ulcerative keratitis and was treated with oral steroid, sulfasalazine, and steroid eye drop. After 1 month of treatment, epithelial thinning of the cornea and peripheral corneal ulcer stopped progressing and showed corneal re-epithelization. CONCLUSIONS: Because peripheral ulcerative keratitis after cataract extraction with clear corneal incision can occur in a patient with rheumatoid arthritis, caution is necessary to minimize damage by careful manipulation during the operation and requires special attention in preoperative and postoperative management.

The Statistical Observation of Ocular Injury in the Military

PURPOSE: We investigated the clinical characteristics of ocular trauma in the military for prevention and treatment application. METHODS: We retrospectively surveyed epidemiologic characteristics by investigating the medical records of 790 patients who were hospitalized in the Armed Forces Capital Hospital from January 1, 2001 to December 31, 2010 and investigated the prognostic factors that influenced visual outcome. RESULTS: Among the 790 patients with ocular trauma, 22.9% of the patients had an open injury and 77.1% had a closed injury. The most common cause of injury was sports-related ocular trauma (39%) and fatigue duty-related trauma (23.4%). The following 8 risk factors were considered poor prognostic factors: open injury, involved posterior segment, operation, initial visual acuity of 0.1 or less, corneal laceration, hyphema, RD, and intraocular foreign body. There was a significant correlation between the probability of poor visual outcome and the number of risk factors (correlation coefficient = -0.468, p < 0.0001). CONCLUSIONS: In the present study, the cause, characteristics and prognostic factor of military personnel's ocular injury were determined. The results can be useful in the prevention and management of ocular injury in the military.

Delayed Sealing of Macular Hole after Vitrectomy with Silicone Oil Tamponade

PURPOSE: To report a case of delayed sealing of full-thickness macular hole associated with diabetic retinopathy after vitrectomy with silicone oil tamponade. CASE SUMMARY: A 63-year-old woman visited our clinic complaining of decreased visual acuity in her left eye. Fundoscopy showed a full-thickness macular hole with vitreomacular traction in the left eye and bilateral proliferative diabetic retinopathy. The patient underwent uncomplicated phacoemulsification and pars plana vitrectomy with silicone oil tamponade because her vision in the contralateral eye was only light perception. She was unable to maintain a prone position postoperatively due to anterior chamber hyphema. At 1.5 months after surgery, vitreomacular traction was removed but the hole was not sealed as observed on optical coherence tomography. Approximately 3 months after vitrectomy, the macular hole was sealed with minimal subfoveal fluid. At 6 months after vitrectomy, the macular hole was closed completely with no subfoveal fluid.

Pattern of pediatric ocular trauma in Kashan

Ocular trauma is a significant health problem in pediatric patients. The aim of this study was to analyze the characteristics of ocular-traumarelated hospitalization of children in Kashan. This descriptive, cross-sectional study included 131 children aged less than 16 years with ocular trauma, who were admitted to the Matini Hospital at the Kashan University of Medical Sciences between April 2006 and March 2009. After admission,detailed ocular examination was performed, and their ocular trauma was classified according to the International Ocular Trauma Classification and Birmingham Eye Trauma Terminology systems. Mean age of the patients was 7.8 +/- 2.2 years [age range, 0-16 years], and male to female ratio 5:1. The most common cause of admission was hyphema [38.1%], followed by corneoscleral laceration [27.5%]. Ocular trauma most commonly occurred at home [43%], and 69% of the patients presented to the emergency room within 24 h of injury. In 30% of the patients, initial visual acuity at the time of presentation was less than 20/200 [Figure 1]. Ocular trauma is a major cause of unilateral blindness, especially in young boys, and hence, preventive measures and education is required
