ABSTRACT
Resumo O hemangioma de coroide é um tumor benigno relativamente raro, que se apresenta de forma circunscrita ou difusa, sendo esta última normalmente associada à Síndrome de Sturge-Weber. Os tumores circunscritos manifestam-se de forma insidiosa, com o diagnóstico realizado comumente após o aparecimento de sintomas secundários. Apresentam como diagnóstico diferencial lesões graves e potencialmente letais, como melanoma de coroide e doença metastática. Neste relato descrevemos o caso de um hemangioma intraocular nodular avançado associado a descolamento hemorrágico da retina, evidenciando o desafio do diagnóstico diferencial devido às semelhanças clínicas e radiológicas compartilhadas pelos tumores.
Abstract Choroidal hemangioma is a fairly rare benign vascular tumor that can manifest in either circumscribed or diffuse type; the latter one is usually related to Sturge-Weber Syndrome. The circumscribed tumors have an insidious presentation and diagnosis is commonly made after the onset of secondary symptoms. Serious and potentially lethal lesions, such as choroidal melanoma and metastatic disease, may represent a differential diagnosis. In this report, we describe an advanced case of nodular hemangioma associated with hemorrhagic retinal detachment. This case highlights the challenge of differential diagnosis in intraocular tumors, due to their similar clinical and radiologic features.

Los glaucomas secundarios son de difícil manejo, independientemente de las causas. Entre ellos, el glaucoma neovascular representa un reto para los oftalmólogos por las causas que lo producen y la gran pérdida visual que provoca. De igual manera, el síndrome iridocorneoendotelial es una enfermedad poco frecuente. El glaucoma ocurre aproximadamente en el 50 por ciento de los casos en dependencia del síndrome que predomine, mucho más grave en la atrofia esencial del iris. Presentamos un caso clínico de una paciente femenina de 58 años de edad en quien aparecen en cada ojo, de manera independiente, estos dos tipos de glaucomas secundarios(AU)
Secondary glaucomas are always difficult to manage, no matter what their causes might be. Among them, neovascular glaucomas pose a challenge to ophthalmologists, due to the factors bringing them about and the great visual loss they produce. On the other hand, iridocorneal endothelial syndrome is an uncommon condition. Glaucoma develops in about 50 percent of the cases, depending on the prevailing syndrome, and is much more severe in essential iris atrophy. A clinical case is presented of a 58-year-old female patient with these two types of secondary glaucoma, one type in each eye(AU)

Introducción: el glaucoma neovascular es un tipo de glaucoma secundario frecuente en los pacientes diabéticos, se produce por la formación de una membrana fibrovascular a nivel del ángulo camerular, como consecuencia de un estímulo angiogénico producido por enfermedades que generan isquemia ocular. Los pacientes con retinopatía diabética proliferativa pueden sufrir esta enfermedad de difícil tratamiento para el oftalmólogo, y que constituye una amenaza para la visión del paciente. Objetivo: revisar aspectos clínicos, patogenia, métodos para el diagnóstico y tratamiento terapéutico del glaucoma neovascular con vistas a prevenir o reducir la pérdida visual. Desarrollo: el glaucoma neovascular es una complicación de la diabetes mellitus y de otras enfermedades generales, que provoca una disminución importante de la visión, y en muchas ocasiones, ceguera. Las enfermedades oculares que con más frecuencia lo producen son la oclusión de la vena central de la retina, la retinopatía diabética proliferativa y el síndrome isquémico ocular, generando isquemia retiniana y coroidea con la consecuente formación de neovasos. Conclusiones: la educación al paciente diabético y el adecuado tratamiento terapéutico de la retinopatía diabética es importante para prevenir la aparición del glaucoma neovascular(AU)
Introduction: neovascular glaucoma is the type of secondary glaucoma common in diabetic patients; it is caused by the formation of fibrovascular membrane at the camerular angle as a result of angiogenic stimulus due to ocular ischemia-generating diseases. The proliferative diabetic retinopathy patients may suffer this difficult-to-treat disease that represents a threat to the vision of a patient. Objective: to review clinical aspects, pathogenenesis, diagnosis methods and treatment of the neovascular glaucoma with a view to preventing or reducing the vision loss. Development: neovascular glaucoma is a complication of diabetes mellitus and of other general diseases, which brings about significant reduction of vision and often blindness. The most frequent eye diseases responsible for this are central retinal vein occlusion, proliferative diabetic retinopathy and ocular ischemic syndrome, leading to retinal and choroid ischemia with resulting formation of neovessels. Conclusions: education aimed at diabetic patient and the adequate therapeutic treatment of the diabetic retinopathy is important to prevent the occurrence of neovascular glaucoma(AU)

Branch retinal artery occlusion (BRAO) and branch retinal vein occlusion (BRVO) rarely cause neovascular glaucoma (NVG). A 58-year-old woman with hypertension and type 2 diabetic mellitus complained of progressive visual loss in her right eye for the previous 3 months. At initial examination, visual acuity was 20 / 63 in the right eye. Angle neovascularization was observed and the intraocular pressure (IOP) was 30 mmHg in her right eye. Fundus examination and fluorescein angiography showed BRAO combined with BRVO. We immediately injected intravitreal and intracameral bevacizumab in her right eye. The next day, we performed scatter photocoagulation in the nonperfusion area. One month later, visual acuity was 20 / 20 in her right eye and the IOP was 17 mmHg with one topical antiglaucoma agent. The neovascularization had regressed completely. We report a case of unilateral NVG which was caused by BRAO with concomitant BRVO and advise close ophthalmic examination of the iris and angle in BRVO with BRAO.

We report two cases of intraocular cysticercosis which showed a peculiar presentation of neovascular glaucoma which is hitherto unreported. Two young adults presented with symptoms of raised intraocular pressure due to neovascular glaucoma. On dilated fundus examination both were found to have dead intravitreal cysticercosis. The cysts were removed by a three-port vitrectomy and intracameral injection of bevacizumab was given to help in the regression of rubeosis. Trabeculectomy had to be combined in one case. The intraocular pressure returned to normal. No recurrence of rubeosis was seen even after one year.

A 13-year-old girl with a right intraorbital optic nerve glioma (ONG) was referred to our glaucoma clinic because of uncontrolled intraocular pressure (IOP) in her right eye. The IOP reached as high as 80 mmHg. Several months earlier, she had undergone stereotactic image-guided robotic radiosurgery using the CyberKnife for her ONG; the mass had become smaller after treatment. Her visual acuity was no light perception. Slit lamp examination revealed rubeosis iridis, a swollen pale optic disc, and vitreous hemorrhage. After medical treatment, the IOP decreased to 34 mmHg, and no pain was reported. Although the mass effect of an ONG can cause neovascular glaucoma (NVG), this case shows that stereotactic radiosurgery may also cause NVG, even after reducing the mass of the tumor. Patients who undergo radiosurgery targeting the periocular area should be followed carefully for complications.

We report a case of ocular ischemic syndrome accompanied by neovascular glaucoma that was successfully treated with Bevacizumab. A 70-year-old male patient diagnosed with neovascular glaucoma of the left eye 3-4 years prior complained of continuous left eye pain and declining visual acuity despite receiving the latest treatment methods. At the time of admission the patient had no light perception in the left eye and his intraocular pressure was 30 mmHg. Anterior segment and fundus examinations revealed neovascularization of the iris and stenosis of the retinal vessel. Hypofluorescence of the choroid and retinal vessels was observed on fluorescence fundus angiography. Left internal carotid artery stenosis was observed on a brain MRI. Despite being treated with eye solution and oral medication, intraocular pressure was not controlled. After 7 days, we performed an intravitreal Bevacizumab 1.25 mg/0.05mL injection. One day after the intravitreal Bevacizumab injection, the neovascularization had nearly regressed and intraocular pressure was 30 mmHg. Intravitreal Bevacizumab injection produced regression of neovascularization and proved effective for treatment of neovascular glaucoma in this case of ocular ischemic syndrome.

Objetivo: Avaliar as causas de glaucoma neovascular (GNV), bem como os fatores que influenciam prognóstico e o resultado do tratamento efetuado. Métodos: Estudou-se retrospectivamente um grupo de 38 pacientes com diagnóstcos de GNV atendidos consecutivamentes no setor de Glaucoma da UNICAMP entre setembro de 1996 e março de 1997. Resultados: A principal causa de GNV encontrada foi retinopatia diabética proliferativa (RDP)em 18 pacientes (47,4 por cento), seguida de oclusäo da veia central de retina (OVCR) em 14 (36,8 por cento). O único fator progóstico positivamente correlacionado à acuidade visual final foi a acuidade visual inicial (p=0,004). Näo houve associaçäo entre pressäo intraocular (PIO) inicial e acuidade visual final, nem tampouco entre extensäo de goniossinéquias e acuidade visual final(p>0,05). Entre os 38 pacientes, 8(21,1por cento) foram submetidos a cirurgia, onde observamos uma diminuiçäo significativa da PIO de 39,75ñ10,99mmHg para 21,88ñ12,14mmHg(p=0,01,)5(13,1por5 cento)obtiveram reduçäo da PIO de 31,4ñ7,4mmHg para 16,0ñ4,6 mmHg graças a tratamento clínico da PIO( medicaçäo anti-glaumatosa + ablaçäo retiniana) (p=0,01).Os demais 25 pacientes (65,8 por cento) näo apresentavam prognóstico visual suficiente que justificasse cirurgia (acuidade visual menor ou igual a percepçäo luminosa). Ao final do período de seguimento, 71,1 por cento dos pacientes apresentaram acuidade visual pior ou igual à percepçäo de luminosa. Conclusäo: O GNV mostrou ser moléstia de difícil controle terapêutico e com prognóstico visual ruim. Na tentativa de minimizar esta evoluçäo desfavorável, propusemos um fluxograma de abordagem do paciente com GNV.

Se efectuó ciclofotocoagulación diascleral (CFCD) con LASER semiconductor de diodos en 14 ojos de 12 pacientes con glaucoma neovascular avanzado, los parámetros que utilizamos fueron: 1750 a 2000 mW de poder, 2 segundo de duración, 20 a 30 aplicaciones 1 mm posterior al limbo córneo-esclerar, con una sonda ®G¼ de iris Medical Instruments, la TIO peroperatoria promedio fue de 47 ñ 13 mm Hg; a los 6 meses se registró una TIO promedio de 30 ñ 18 mm Hg y al año 30 ñ 15 mm Hg en 7 de los ojos en estudio (prueba t de Student pareada p= 0.03). El promedio de medicamentos antiglaucomatosos utilizados preoperatoriamente fue 2.5 ñ 0.62 a los 6 meses y al año se emplearon 1.57 ñ 0.72. Todos los ojos tratados con CFCD presentaron inflamación conjuntival leve y fenómeno de Tyndall+ que se resolvió en el transcurso de una a dos semanas. Estos resultados sugieren que la CFCD con LASER semiconductor de diodos pueden ser de utilidad en el tratamiento de glaucoma neovascular
