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 profile, multimodal imaging, and treatment response in macular serpiginous choroiditis

Purpose: To describe the clinical profile, multimodal imaging, and treatment response in macular serpiginous choroiditis (MSC). Methods: Clinical records of 16 eyes (14 patients) with MSC presenting to a tertiary eye care institute between 2015 and 2019 were analyzed retrospectively. Results: Mean age of 14 patients presenting with MSC was 33 ± 13 yrs with 64% males and 36% females. Mean visual acuity of the eyes with MSC at presentation was 0.43 ± 0.46 (logMAR) improving to 0.16 ± 0.28 (logMAR) at final visit. Thirteen eyes (81.3%) had active lesion at presentation. Mantoux test was positive in seven patients (50%) and QuantiFERON TB gold test positive in 10 patients (71%). HRCT chest showed latent tuberculosis in seven patients (50%). All patients underwent multimodal imaging. All patients received oral steroids as treatment therapy; 11 patients also received immunosuppressives, nine patients received additional anti?tubercular therapy (ATT). Mean duration of follow?up for the patients was 18 ± 10 months. A total of eight (50%) eyes had recurrence of lesions after an average duration of 14 ± 14 (3?36) months and were restarted on the treatment as per the requirement. At final follow?up, all eyes showed a good response to treatment and had healed lesions. Comparing the final BCVA to the initial BCVA, 38% (n = 6) showed improvement, 56% (n = 9) remained stable, and 6% (n = 1) eyes worsened at the final follow?up. Conclusion: Clinical profile and presentation of MSC is similar to that of CSC, and combination treatment with intravenous methyl prednisolone (IVMP), steroids, immunosuppressives, and ATT can salvage vision. A high suspicion of associated tuberculosis in endemic regions should be kept in mind.

Clinical observation on the evolution of fundus lesions in different subtypes of serpiginous choroiditis / 中华眼底病杂志

Objective:To observe the clinical evolution process and imaging characteristics of choroidal lesions in different subtypes of serpiginous choroiditis (SC), and to explore the clinical significance of subtype classification.Methods:A retrospective, uncontrolled and observational study. A total of 45 eyes of 25 SC patients diagnosed in Yunnan Eye Hospital from May 2009 to September 2021 were included in the study. According to the initial location of the lesion and fundus images, including fundus color photography, fundus fluorescein angiography (FFA), optical coherence tomography (OCT) and other examination results. SC was divided into peripapillary serpiginous choroiditis, macular serpiginous choroiditis and ampiginous choroiditis. According to the shape of the lesions at the first diagnosis, it can be divided into new lesions with only infiltrating edema, old lesions with only atrophy and recurrent lesions with coexistence of edema and atrophy. the imaging features, development and complications of different subtypes of ocular lesion were observed.Results:Among the 45 eyes of 25 cases, 15 cases were male and 10 cases were female, 20 cases of binocular and 5 cases of monocular, age was 42.3±5.7 years old. There were 21 eyes with active lesions, of which 5 eyes were new lesions and 16 eyes with recurrent lesions; 24 eyes were old lesions. Concurrent optic disc edema occurred in 3 eyes; mild vitreitis occurred in 5 eyes; retinal occurred vasculitis in 3 eyes; choroidal neovascularization occurred in 3 eyes. Among the 16 cases (64%, 16/25) of the peripapillary serpiginous choroiditis, 2 cases (2 eyes) were monocular, and 14 cases (28 eyes) were binocular. Active lesions were found in 16 eyes, of which patients with binocular lesions only one had active lesions. The choroidal lesions that were close to the optic disc or around the optic disc, expanded outwards centrifugally with the prolongation of the disease course, and can progress to the macula. The edge of the lesion was tortuous, with a geographic-like, amoeboid-like and finger-like, polypoid or propeller-like shape. Active lesions in FFA showed weak fluorescence in the early stage and strong fluorescence in the late stage; the old lesions showed weak fluorescence in the early stage and mottled fluorescence in the late stage, and mostly strong fluorescence on the edge. OCT showed thickening of active lesions and thinning of old lesions. Among the 4 cases (16.0%, 4/25) of macular type, 2 cases (2 monocular eyes) had active lesions; 2 cases (4 eyes) had lesion in both eyes, among them, 1 case (2 eyes) had old lesion, and the other case had alternate active lesions. The initial lesions were all located in the off-center of the macula, and most of them were disk-shaped and progressing centrifugally to the periphery. The FFA and OCT imaging findings of the lesions were similar to those of the peridisc type. Among the 5 cases (20.0%, 5/25) of ampiginous choroiditis, 1 case (1 eye) was monocular and 4 cases (8 eyes) were binocular. These lesions were multiple old lesions of varying sizes, gray-white with pigmentation, with clear borders in the posterior pole. Among them 4 eyes have new active lesions appeared near the old lesions. The old lesions showed weak fluorescence with clear borders, and the fluorescein leakage at the late edge formed a strong fluorescence ring; the active lesions showed weak fluorescent spots with blurred edges, and the fluorescence was slightly enhanced in the late stage. In old lesions, atrophy of the photoreceptor layer, RPE and choroid can be seen, and RPE hyperplasia in some areas.Conclusions:SC subtype is a classification of the location of the first lesion, but the characteristics of the repeated attack of this disease can lead to the annihilation of each subtype due to the continuous expansion of the lesion. The phenomenon that the fundus active lesions only occur in one eye that can explain the clinical manifestations of asymmetric morphology of binocular lesions. The characteristics of binocular subtype warn that the predilection site of the healthy eye should be paid attention to.

Enigma of serpiginous choroiditis

Serpiginous choroiditis (SC) is an asymmetrically bilateral inflammation of the choroid that leads to loss of choriocapillaris atrophy or loss of overlying retinal pigment epithelium. Over the last few decades, SC has passed through a long evolution of nomenclature, etiologies and morphological variations. Initially diagnosed in patients with tuberculosis and syphilis, SC was predominantly considered as autoimmune process. With the advancement of molecular diagnosis, a new aspect of infectious subtypes of SC has emerged out. The terminologies such as serpiginous-like choroiditis (SLC) and multifocal serpiginoid choroiditis are now used to denote the subtypes of SC which are associated with infectious etiologies especially tuberculosis. In a country endemic for tuberculosis such as India, it is very important to differentiate between classic SC and SLC before initiating aggressive immunomodulatory therapy. Also, management of paradoxical worsening of the clinical condition with antitubercular treatment is another challenge in SLC and ophthalmologists should be aware of such situations. With advent of newer imaging modalities, monitoring the patient with choroiditis and identification of complications such as choroidal neovascular membrane have become much easier. This article aims to review the existing literature on SC with a special emphasis on management of SC and SLC.

Research advance in clinical application of multimode imaging in Serpiginous choroiditis / 国际眼科杂志(Guoji Yanke Zazhi)

@#Serpiginous choroiditis(SC)is a rare, chronic-idiopathic inflammatory disease mainly involving choriocapillaris and the retinal pigment epithelium(RPE), characterized by grayish yellow geographic lesions. Pathogenesis is unclear, the choriocapillaris is a main pathology of SC. Based on clinical presentation, it can be classified into peripapillary, macular, and ampiginoustype. The clinical appearance of SC is varied and similar to those of acute posterior multifocal placoid pigment epitheliopathy(APMPPE), tuberculosis, toxoplasmosis and choroidal ischemia. So, it is still difficult to diagnose SC without typical fundus symptoms.With the development of science and technology, multimode imaging such asfundus fluorescein angiography, indocyanine green angiography, fundus autofluorescence and optical coherence tomography are helpful for the diagnosis of SC, assessment of lesion extent, activity, and complications. Besides, it's very important to avoid unnecessary drug use.

The Clinical Manifestations and Differential Diagnosis of Tuberculosis Serpiginous-like Choroiditis and Serpiginous Choroiditis

PURPOSE: The purpose of this study is to make a distinction between tuberculous serpiginous-like choroiditis and serpiginous choroiditis, and compare their clinical manifestations. METHODS: We retrospectively reviewed thirty eight eyes of twenty-six patients who visited our institution and were diagnosed with serpiginous choroiditis from January 2005 to December 2014. The patients were divided into two groups, tuberculosis serpiginous- like choroiditis (Tb-SLC) and classic serpiginous choroiditis (classic SC), and were analyzed based on the treatment response, previous history of Bacillus Calmette–Guérin (BCG) vaccination, positive results of tuberculin skin test (TST), chest X-ray, anterior and fundus examination, and fluorescein angiography (FAG). RESULTS: Twenty seven eyes of eighteen patients were serpiginous choroiditis and eleven eyes of eight patients were tuberculosis serpiginous-like choroiditis. There were no significant differences in age, sex, or previous history of BCG vaccination between the two groups. The positive result of the tuberculin skin test and abnormality in the chest X-ray were shown to be significantly higher in the Tb-SLC group. Multi-focal lesions involving periphery observed in fundus examination and FAG were significantly higher in Tb-SLC. CONCLUSIONS: In tuberculosis endemic areas such as Korea, tuberculosis serpiginous-like choroiditis should be considered as a differential diagnosis when the patient is suspicious of serpiginous choroiditis. The understanding of various clinical manifestations of tuberculosis serpiginous-like choroiditis may derive accurate diagnosis and treatment, enhancing patient's prognosis.

Profile of serpiginous choroiditis in a tertiary eye care centre in eastern India.

Purpose: To study the clinical profile of serpiginous choroiditis in eastern India. Materials and Methods: Ninety‑one eyes of 54 patients with serpiginous choroiditis presenting to a tertiary care centre in eastern India between January 2006 and December 2010 were included in the study. Clinical presentation, treatment given, and visual outcome of the eyes were studied. Results: Thirty‑five (64.8%) patients were male and 19 (35.2%) were female in the age group of 13‑62 years (mean age: 34.1 ± 18.7 years). Blurring of vision (71; 78%) and floaters (36; 39.5%) were commonest symptoms. In 75 (82.4%) eyes, choroiditis started from optic nerve head and spreading centrifugally. Overall, 38 (41.75%) eyes had macular involvement at first visit. Mantoux test reading was 10 mm or more (Group A) in 12 (22.22%) patients and less than 10 mm (Group B) in 42 (77.77%) patients. Difference between Groups A and B in macular involvement at first visit (10; 50% vs. 28; 39.4%) and rate of recurrence (3; 15% vs. 14; 19.7%) was not statistically significant (P = 0.37 and 0.68). Oral steroid (51; 94.4%) was the commonest mode of treatment. Fifty‑one (56%) eyes had two lines or more improvement in vision. Conclusions: The present study details the clinical presentation, treatment, and visual outcome of serpiginous choroiditis. Mantoux test reading does not affect the clinical presentation or the treatment outcome in these eyes.

Serpiginous choroiditis and acute retinal necrosis occurring in the same patient.

We describe a rare association of serpiginous choroiditis with necrotizing retinitis having clinical features of acute retinal necrosis (ARN). A 23-year-old male developed ARN in the fellow eye while he was on tapering doses of immunosuppressive medications for unilateral serpiginous choroiditis. The association may represent a common viral etiology of the two diseases or may be due to the development of ARN due to general state of iatrogenic immunosuppression. This report also highlights the importance of a detailed evaluation of both the eyes on regular follow-up visits in the patients receiving iatrogenic immunosuppression.

Indocyanine green angiography in posterior uveitis.

Literature review for indocyanine green angiography and evaluate the role of indocyanine green angiogram (ICGA) in patients with posterior uveitis seen at a tertiary referral eye care centre. Detailed review of the literature on ICGA was performed. Retrospective review of medical records of patients with posterior uveitis and dual fundus and ICGA was done after institutional board approval. Eighteen patients (26 eyes) had serpiginous choroiditis out of which 12 patients had active choroiditis and six patients had healed choroiditis, six patients (12 eyes) had ampiginous choroiditis, six patients (12 eyes) had acute multifocal posterior placoid pigment epitheliopathy, eight patients (10 eyes) had multifocal choroiditis, four patients (eight eyes) had presumed ocular histoplasmosis syndrome, four patients (eight eyes) had presumed tuberculous choroiditis, two patients (four eyes) had multiple evanescent white dot syndrome and two patients (four eyes) had Vogt Koyanagi Harada (VKH) syndrome. The most characteristic feature noted on ICGA was the presence of different patterns of hypofluorescent dark spots, which were present at different stages of the angiogram. ICGA provides the clinician with a powerful adjunctive tool in choroidal inflammatory disorders. It is not meant to replace already proven modalities such as the fluorescein angiography, but it can provide additional information that is useful in establishing a more definitive diagnosis in inflammatory chorioretinal diseases associated with multiple spots. It still needs to be determined if ICGA can prove to be a follow up parameter to evaluate disease progression.

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.

A Case of Serpiginous Choroiditis Beginning in the Posterior Pole

Serpiginous choroiditis is a chronic. progressive, recurrent, and usually bilateral disease involving the choriocapillaris, retinal pigment epithelium, and retina. This disease classically involves the juxtapapillary retina and extends outward in a pseudopodial fashion. We report a case of serpiginous choroiditis beginning in the posterior pole without initial peripapillary lesion, and extending toward the optic disc. The fluorescein angiogram of the lesion showed hypofluorescence in the early phase and hyperfluorescence in the late phase, and the progression of the lesion with time.
