Descolamento seroso de coroide como manifestação tardia da síndrome de Vogt-Koyanagi-Harada / Serous choroidal detachment in chronic stage of Vogt-Koyanagi-Harada syndrome

Resumo Relatamos um caso atípico de uma paciente de 40 anos com apresentação completa da Síndrome de Vogt-Koyanagi-Harada (SVKH) que após 17 anos do diagnóstico inicial evoluiu com descolamento seroso de coroide. A paciente procurou atendimento com queixa de dor em olho esquerdo (OE). O exame oftalmológico revelou acuidade visual (AV) igual a de movimento de mãos, à biomicroscopia foi observada reação inflamatória granulomatosa na câmara anterior, a tonometria foi igual a 0 mmhg, e a fundoscopia indevassável pela pouca midríase e turvação de meios em OE. O descolamento seroso de coroide foi avaliado através de ultrassonografia ocular. A abordagem terapeutica intituida para paciente consistiu em prednisona 1mg/kg/dia via oral, dexametasona 1mg/mL e atropina 1% colírios. A evolução do quadro foi satisfatória, com melhora da AV para 20/40, ausência de reação inflamatória em câmara anterior, normalização da pressão intraocular e resolução do descolamento seroso de coroide em OE. Concluimos que a fase crônica da SVKH, apesar da manifestação classicamente descrita ser uveíte anterior, pode ter outras apresentações e o descolamento seroso da coroide é uma rara complicação.

Abstract We report an atypical case of a 40-year-old woman with complete presentation of Vogt-Koyanagi-Harada Syndrome (VKH) who presented with unilateral serous choroidal detachment 17 years after the diagnosis. The patient complained of pain in the left eye, the ophthalmologic examination revealed visual acuity (VA) equal to hand motion; biomicroscopy revealed a granulomatous inflammatory reaction in the anterior chamber, tonometry was equal to 0 mmhg, and the fundoscopy was impracticable. Serous choroidal detachment was assessed by ocular ultrasonography. The therapeutic approach proposed for the patient consisted of prednisone 1mg / kg / day orally, dexamethasone 1mg / mL and atropine 1% eye drops. The evolution of the condition was satisfactory, with VA improvement to 20/40, absence of inflammatory reaction in anterior chamber, normalization of intraocular pressure and resolution of serous choroidal detachment in OS. We conclude that the chronic phase of VKH, although classically described as anterior uveitis, may have other presentations and the serous choroid detachment is a rare complication.

Silent polypoidal choroidal vasculopathy in a patient with angioid streaks / Vasculopatia polipoidal de coróide quiescente em um paciente com estrias angióides

ABSTRACT We present a case of silent polypoidal choroidal vasculopathy (PCV) in a patient with angioid streaks. PCV was detected during a routine ophthalmic examination and confirmed by fluorescein angiography, indocyanine green angiography, and optical coherence tomography. After 2 years of follow-up, the PCV remained silent without any complications. We report this rare coexistence and review literature on this topic.

Após 2 anos de seguimento a vasculopatia polipoidal de coroide permaneceu quiescente, sem qualquer complicação. Nós relatamos esta coexistência rara e apresentamos revisão da literatura.

Prevalência de cicatrizes coriorretinianas em exames angiográficos / Prevalence of chorioretinal scars in angiographics exams

RESUMO A toxoplasmose é uma zoonose que tem como agente etiológico o Toxoplasma gondii, que se caracteriza por ser uma doença infecciosa de distribuição mundial. Considera-se que no mundo existam mais de 2 bilhões de pessoas infectadas pela toxoplasmose. É bem conhecido que a toxoplasmose é uma causa frequente de cicatriz coriorretiniana. Nesse grupo de doenças, o exame angiográfico (ou angiofluoresceinografia de retina) é de fundamental importância para o diagnóstico. Objetivo: Realizar um levantamento da prevalência de cicatrizes coriorretinianas em angiografias em serviço privado na região de Cascavel (PR), Brasil. Métodos: Realização um estudo retrospectivo, transversal, com levantamento de documentos fonte, onde foram analisados 8719 laudos de angiografias de retina realizadas no Instituto da Visão na cidade de Cascavel (PR), Brasil, entre os anos de 2000 a 2011, sendo selecionados como primeiro diagnóstico de cada paciente, completando um total de 4928 exames válidos. As alterações encontradas foram classificadas de acordo com o tipo de cicatriz visualizada, e divididas conforme frequência percentual. Resultados: Observou-se uma prevalência de cicatrizes de 6,38%, sendo que o percentual de cicatriz coriorretiniana encontrado foi de 6,14%. Conclusão: A baixa prevalência de cicatrizes coriorretinianas encontrada na região de Cascavel (PR), Brasil, quando comparada à de Erechim (RS), Brasil, se deve a diversos fatores, tanto climáticos, socioculturais e institucionais. Além das cicatrizes coriorretinianas, que representaram o maior número entre as cicatrizes, foram encontrados outros subtipos cicatriciais com prevalências menores.

ABSTRACT Toxoplasmosis is a zoonosis whose etiologic agent is Toxoplasma gondii, which is characterized as an infectious disease of worldwide distribution. There are thought to be more than 2 billion people globally infected with toxoplasmosis. It is well known that toxoplasmosis is a frequent cause of chorioretinal scarring. In this group of diseases, the angiographic examination (or retinal fluorescein angiography) is very important for diagnosis. Objective: To perform a survey on the prevalence of chorioretinal scars in angiography at a private clinic in the area of Cascavel, Paraná State, Brazil. Methods: This was a retrospective, cross-sectional study with collection of data from source documents, involving the analysis of 8,719 reports of retinal angiograms performed at the Instituto da Visão of Cascavel, Brazil, between the years 2000-2011. The first diagnosis of each patient was selected, completing a total of 4,928 valid exams. The changes were classified according to the type of visualized scarring, and divided as percentage frequency. Results: We observed a prevalence of 6.38% scars, and the percentage of chorioretinal scars was found to be 6.14%. Conclusion: The low prevalence of chorioretinal scars found in the region of Cascavel, Brazil, when compared with the region of Erechim (Rio Grande do Sul State), Brazil, is due to climatic, sociocultural and institutional factors. Besides the chorioretinal scars, which represent the largest group of scars, other subtypes of scars with lower prevalence were found.

Aflibercept Treatment for Neovascular Age-related Macular Degeneration and Polypoidal Choroidal Vasculopathy Refractory to Anti-vascular Endothelial Growth Factor

PURPOSE: To report the results of switching treatment to vascular endothelial growth factor (VEGF) Trap-Eye (aflibercept) in neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) refractory to anti-VEGF (ranibizumab and bevacizumab). METHODS: This is a retrospective study involving 32 eyes from 29 patients; 18 were cases of neovascular AMD and 14 were cases of PCV. The best-corrected visual acuity (BCVA) and central macular thickness (CMT) of spectral-domain optical coherence tomography were evaluated. RESULTS: BCVA and CMT improved from 0.58 to 0.55 (p = 0.005) and from 404 to 321 microm (p < 0.001), respectively, after switching to aflibercept. The 14 eyes that received 6 or more aflibercept injections remained stable at 0.81 to 0.81 and 321 to 327 microm (p = 1.0, 0.29), respectively, after 3 aflibercept injections. The 10 eyes that received 3 or more bevacizumab injections after 3 or more aflibercept injections worsened, from 0.44 to 0.47 and from 332 to 346 microm (p = 0.06, 0.05), respectively. The results showed similar improvement of BCVA and CMT in neovascular AMD and PCV. CONCLUSIONS: Aflibercept seems to be effective for improvement and maintenance of BCVA and CMT for neovascular AMD and PCV refractory to anti-VEGF. Switching from aflibercept back to bevacizumab treatment may not be a proper strategy.

Clinical Characteristics of Polypoidal Choroidal Vasculopathy Associated with Chronic Central Serous Chorioretionopathy

PURPOSE: To investigate the clinical characteristics of polypoidal choroidal vasculopathy (PCV) associated with chronic central serous chorioretinopathy (CSC). METHODS: We retrospectively reviewed the medical records of 246 PCV patients (283 eyes) between July 2004 and August 2009 and investigated the clinical characteristics of the PCV patients who had specific fundus findings of chronic CSC. RESULTS: Among PCV patients, 13 eyes (4.6%) of 13 PCV patients (5.3%) had fundus findings of chronic CSC. All of the PCV lesions had a solitary polyp located outside the atrophic retina, predominantly in the macular area (84.6%), most showed an exudative pattern (69.2%) and there were a few that showed a hemorrhagic pattern (30.8%). All of the lesions were smaller than 1 disc diameter. Most of the PCV lesions (76.9%) were cured with less than two treatments in a short period of 6.4 +/- 1.9 months; however, visual acuity deteriorated (61.5%) or was not changed (30.8%) in most of the cases. CONCLUSIONS: The PCV associated with chronic CSC had several clinical features such as a small exudative retinal lesion with a solitary polyp and frequent involvement of the macular area. Even though there was poor visual outcome due to the atrophic change, all of the PCV lesions were easily resolved in a short period with a simple treatment course and no recurrence.

Intravitreal ranibizumab for the treatment of choroidal neovascularization secondary to ocular toxoplasmosis.

The purpose of the study was to report a case of choroidal neovascularization (CNV) secondary to ocular toxoplasmosis in an 18-year-old female patient. She was treated with a single intravitreal injection of ranibizumab. The CNV resolved as confirmed by fluorescein angiography and optical coherence tomography (OCT). The visual acuity improved to 20/30, which was maintained till the last follow-up visit at two years, without requisition of a repeat injection.

Flare up of choroiditis and choroidal neovasculazation associated with punctate inner choroidopathy during early pregnancy.

A 28-year-old, healthy female, who had a recent repeated history of miscarriage, presented with bilateral choroidal neovascular membranes (CNVM), for which she received photodynamic therapy with three doses of lucentis, at intervals of one month each, to which she responded. After five months, the patient again presented with complaints of diminution of vision since 15 days. She had a history of miscarriage two days before presenting to our clinic. CNVM was scarred at this time and the fundus picture showed multiple small punctate spots around the fovea at the level of the choroid, which showed early hyperfluroscence on fundus fluorescein angiography, suggestive of punctate inner choroidopathy. She was advised systemic steroids, to which she responded dramatically.

The Development of Recurrent Choroidal Neovascularization in a Patient with Choroidal Coloboma

We report a case of recurrent choroidal neovascularization (CNV) in an eye with chorioretinal coloboma. A 36-year-old woman presented complaining of decreased visual acuity (VA) in her left eye. Best corrected visual acuity (BCVA) was 20/200 and iris coloboma was observed. Funduscopy and fluorescein angiography (FA) showed CNV in the superior extrafoveal region with chorioretinal coloboma reaching just inferior to the optic disc. No other cause for CNV was observed except for the chorioretinal coloboma. BCVA improved to 20/30 after laser photocoagulation. She revisited our clinic for deteriorating VA (20/400) in the same eye 3 years after treatment. Funduscopy and FA demonstrated recurrent CNV with subfoveal hemorrhage. Photodynamic therapy (PDT) was followed by three consecutive intravitreal bevacizumab injections (IVB) for the subfoveally-located CNV. However, the CNV persisted with the appearance of a fresh subretinal hemorrhage. Additional PDT was combined with IVB on the same day 6 months after the initial PDT. The CNV regressed 3 months after treatment and has not recurred as of 8 months after the last treatment. The patient's BCVA improved to 20/60. This case suggests that PDT combined with IVB can be an alternative treatment for the management of recurrent CNV after laser photocoagulation in eyes with chorioretinal coloboma.

A Case of Chorioretinal Coloboma in a Patient with Achondroplasia

Achondroplasia is a congenital disorder resulting from a specific disturbance in endochondral bone formation. The ophthalmic features reportedly associated with achondroplasia are telecanthus, exotropia, inferior oblique overaction, angle anomalies and cone-rod dystrophy. This is first report of chorioretinal coloboma in achondroplasia. An 8-year-old female was diagnosed with a developmental delay, known as achondroplasia, seven months after birth. Upon her initial visit, visual acuity was 0.3 in both eyes. The patient had telecanthus but normal ocular motility. Findings were normal upon anterior segment examination. Fundus examination of both eyes revealed about 1,500 microm sized chorioretinal coloboma inferior to the optic nerve head. Upon fluorescent angiography, there was chorioretinal coloboma without any other lesions. Afterward, there was no change in the fundus lesion, and best corrected visual acuity was 0.6 in both eyes. Chorioretinal coloboma is associated with choroidal and retinal detachment. As chorioretinal coloboma and achondroplasia are developmental disorders in the embryonic stage, early detection and regular ophthalmologic examination would be essential in patients with achondroplasia.

Two Cases of Uveal Effusion Syndrome

PURPOSE: To report a case of uveal effusion syndrome associated with hypotony and a case of uveal effusion syndrome in nanophthalmos. METHODS: The first case was a 25-year-old man who presented with decreased visual acuity in the left eye and hypotony. Fundus examination revealed choroidal effusion and retinal detachment with a thickened eyeball. Partial thickness sclerotomy and sclerectomy were performed. The second case was a 13-year-old boy who had uveal effusion syndrome with a nanophthalmic eye. RESULTS: In the patient with hypotony, intraocular pressure was well maintained following partial thickness sclerotomy and sclerectomy, and choroidal effusion and retinal detachment were reduced. The visual acuity of the nanophthalmic patient was well maintained during a 3-year follow-up period without treatment. CONCLUSIONS: appropriate treatment modalities should be considered depending on the ophthalmic condition of the individual patient.

Surgical Management of Bilateral Exudative Retinal Detachment associated with Central Serous Chorioretinopathy

PURPOSE: To report a case of bilateral bullous exudative retinal detachment in central serous chorioretinopathy (CSC) which was attached by vitrectomy and internal drainage of the subretinal fluid. METHODS: A 47-year-old man affected by bilateral atypical CSC with a bullous retinal detachment with subretinal exudate. A fluorescein angiogram (FAG) showed multiple points of leakage and staining of subretinal fibrosis. A tentative diagnosis of Vogt-Koyanagi-Harada (VKH) syndrome was made and the patient was treated with systemic corticosteroids and immunosuppressive agents. However, the subretinal fluid was not absorbed. He was then treated with vitrectomy and internal drainage of subretinal fluid. RESULTS: The retina was attached successfully in both eyes. Visual acuity improved to 20/50 in his left eye but did not improve in the right eye due to subretinal fibrotic scarring and atropic changes on the macula. CONCLUSIONS: Our case suggests that the surgical management of bullous exudative retinal detachment is safe and necessary.
