Primer Consenso Chileno de Grupo de Estudio de Tuberculosis Ocular

Introducción: El tratamiento de la tuberculosis (TB) ocular es un tema que genera controversia en el mundo. Para el correcto manejo de estos pacientes, es necesario el desarrollo de guías que consideren la epidemiología de la TB ocular en cada nación. El objetivo de este consenso fue discutir de forma interdisciplinaria la epidemiología, fisiopatología, clínica, diagnóstico, estudio y tratamiento de los pacientes con TB ocular, para establecer un algoritmo de tratamiento y proponer qué pacientes deben ser tratados en Chile y con qué tratamiento. Además, se establecieron acuerdos para efectuar quimioprofilaxis de los pacientes con TB latente que tienen indicación de tratamiento inmunosupresor por enfermedades inflamatorias oculares.

The treatment of ocular tuberculosis (TB) remains controversial worldwide. The development of guidelines for ocular TB can facilitate the approach and management of these patients. These guidelines should be developed regionally, considering the local TB epidemiology. The objectives of this consensus are: to initiate an interdisciplinary discussion about the epidemiology, pathophysiology, clinical presentation, diagnosis, workup and treatment of patients with ocular TB, to establish a treatment algorithm and define which patients should be treated in Chile and how and, to analyze and discuss the published data regarding chemoprophylaxis for patients with latent TB who need to start immunosuppressive treatment due to inflammatory ocular conditions.

Clinical case: Serpiginous-like choroiditis with macular involvement and good response after treatment with adalimumab.

Clinical case of a 42-year-old woman who consulted for decreased vision in the left eye over two months, associated with multifocal choroiditis. Different diagnostic tests were performed to rule out infectious pathologies, as well as a diagnostic vitrectomy test, which was negative. QuantiFERON® was found to be positive and a diagnosis of serpeginous-like choroiditis (SLC) was made. Anti-tuberculosis treatment was started with worsening of vision and multifocal choroiditis. Once conventional immunotherapy and biological treatment were added, the patient presented a significant improvement in vision. To conclude, in cases of CSL, it is not only necessary to treat the infection but also the inflammatory component either with steroids or conventional immunotherapy or immunosuppression with biologics, thus reducing the number of reactivations and improving the visual prognosis.

Caso clínico: coroiditis serpiginosa-like con afectación macular y buena evolución tras tratamiento con adalimumab / Clinical case: Serpiginous-like choroiditis with macular involvement and good response after treatment with adalimumab

Se presenta el caso clínico de una mujer de 42 años, que consultó por disminución de visión del ojo izquierdo de 2 meses evolución, asociada a coroiditis multifocal. Se realizaron diferentes pruebas diagnósticas para descartar enfermedad infecciosa, al igual que se realizó una vitrectomía diagnóstica, que resultó negativa. Se encontró QuantiFERON® positivo y se realizó el diagnóstico de coroiditis serpiginosa-like (CS-L). Se inició tratamiento antituberculoso con empeoramiento de la visión y de la coroiditis multifocal. Una vez que se agregaron inmunoterapia convencional y tratamiento biológico, la paciente presentó mejoría significativa de la visión. Para concluir, en casos de CS-L no solo es necesario el tratamiento de la infección, sino también del componente inflamatorio, sea con inmunoterapia convencional o inmunosupresión con biológicos, y así disminuir el número de reactivaciones mejorando el pronóstico visual (AU)

Choroidal neovascularisation secondary to serpiginous choroiditis: The value of OCT-angiography in diagnosis and response to therapy with aflibercept. / Neovascularización coroidea secundaria a coroiditis serpiginosa: valor de la OCT-angiografía en el diagnóstico y en la respuesta al tratamiento con aflibercept.

A case is presented of a 61 year-old man with a personal history of serpiginous choroiditis (SC), who presented with metamorphopsia and decreased visual acuity (VA) in his right eye (RE). In the examination, using Swept Source OCT-angiography (SS OCT-A), peripapillary haemorrhage secondary to a choroidal neovascularisation (CNV) was observed. The patient was treated with intravitreal aflibercept, having a favourable outcome on his symptomatology and in the SS OCT-A findings. CNV is a complication that can appear in up to 25% of cases after SC. An accurate diagnosis using SS OCT-A, with early treatment with aflibercept, led us to obtain optimal clinical and anatomical results.

Presentación de dos casos de coroiditis serpiginosa / Presentation of two serpiginous choroiditis cases

La coroiditis serpiginosa es una patología poco frecuente, bilateral, crónica y recurrente. Los pacientes en edad media de la vida se ven más afectados y con un ligero predominio en varones. Sobre esta enfermedad se presentan dos casos y se hace una breve reseña de sus características clínicas, diagnósticas y de tratamiento. El tiempo de observación clínica fue de tres años, con una edad promedio de 36 años. Predominó el sexo femenino y la forma de presentación bilateral asimétrica. Una paciente refirió como antecedente personal la hipertensión arterial. El diagnóstico se realizó mediante examen clínico oftalmológico y estudio angiográfico. El tratamiento consistió en terapia combinada inmunosupresora (prednisona, ciclosporina). El pronóstico visual en la coroiditis serpiginosa está determinado por la afectación macular. La terapia combinada con inmunosupresores no evitó las recurrencias en estos pacientes.

The serpiginous choroiditis is a non frequent, bilateral chronic and recurrent pathology. The middle-aged patients are mostly affected, with slight predominance of males. Two cases of this disease were presented, and brief review of the clinical characteristics, the diagnosis and the treatment of this pathology was made. The time of clinical observation was 3 years; the average age was 36 years. Females prevailed as well as the bilateral form of presentation. One patient had a history of blood hypertension. The diagnosis was based on clinical ophthalmological exam and angiographic study. The treatment consisted of combined immunosuppressive therapy (prednisone and cyclosporine). The visual prognosis is determined by the macular effect. The combined therapy with inmunosuppresors did not prevent relapses in these patients.
