Hyper-Reflective Outer Nuclear Layer (HONL) in Vogt-Koyanagi-Harada Disease and Sympathetic Ophthalmia.

PURPOSE: To describe the optical coherence tomography (OCT) findings of hyper-reflective outer nuclear layer (HONL) in two cases of stromal choroiditis (Vogt-Koyanagi-Harada disease - VKH, and sympathetic ophthalmia - SO). METHODS: Case report. RESULTS: Clinical and imaging findings of two patients (37-year-old female with VKH and 34-year-old male with SO) have been described. Both patients showed typical features of the disease with subretinal fluid accumulation and choroidal thickening on OCT. However, OCT of both patients at the initial visit revealed HONL, which was unusual in these conditions. During follow-up, OCT scans revealed thinning and atrophy of the outer retinal layers, irregular thickening of the retinal pigment epithelium, and irregular autofluorescence pattern on autofluorescence imaging. CONCLUSIONS: The presence of HONL may serve as a poor prognostic factor in VKH and SO, resulting in thinning and atrophy of the outer retinal layers.

Evolution of retinal changes measured by optical coherence tomography in the assessment of hydroxychloroquine ocular safety in patients with systemic lupus erythematosus.

OBJECTIVE: The objective of this report is to analyse retinal changes over a five-year period, assessed by spectral domain-optical coherence tomography (SD-OCT), in patients from the Lupus-Cruces cohort treated with hydroxychloroquine (HCQ). METHODS: SD-OCT screening was performed annually between 2012 and 2017. Average macular thickness (AMT), ganglion cell layer thickness (GCLT) and qualitative data of retinal pigment epithelium (RPE) and external retina (ExtR) were collected prospectively. We compared data from 2012 (first) and 2017 (second) SD-OCT. RESULTS: We studied 110 patients and 195 eyes. No cases of HCQ toxicity were detected. At the time of the second SD-OCT, 99% patients had taken a daily dose of HCQ ≤5 mg/kg/day. The median time on HCQ was 133 months. The mean AMT and GCLT were significantly lower in both eyes at the second SD-OCT; however, all the differences were clinically insignificant at less than 1%. Qualitative analysis of RPE and ExtR showed no significant changes. Similar results were found among patients with risk factors for retinopathy. The comparison of patients with and without risk factors showed no differences. CONCLUSIONS: This study shows clinically irrelevant retinal changes in an SLE cohort on HCQ treatment over a five-year follow-up. Our findings support the safety of long-term HCQ at doses ≤5 mg/kg/day.

Escleritis anterior tuberculosa: un reto diagnóstico / Anterior tuberculous scleritis: a diagnostic challenge

CASO CLÍNICO: Presentamos el caso de un varón de 26 años de origen pakistaní que, posteriormente al diagnóstico presuntivo de escleritis anterior tuberculosa (por un aspecto biomicroscópico atípico y un nexo epidemiológico positivo), fue diagnosticado de enfermedad tuberculosa pulmonar. DISCUSIÓN: La escleritis anterior nodular es una forma infrecuente de presentación de tuberculosis (TB). Se considera un reto diagnóstico por la dificultad para extraer bacilos del tejido ocular. Sin embargo, una historia clínica y una exploración oftalmológica detalladas pueden ser claves para un diagnóstico certero y un adecuado tratamiento de TB

CASE REPORT: We present the case of a 26 year-old Pakistani male, who after the presumptive diagnosis of anterior tuberculous scleritis (by an atypical clinical appearance and positive epidemiological link), was diagnosed with pulmonary tuberculosis. DISCUSSION: Nodular anterior scleritis is an uncommon presentation of tuberculosis (TB). It is considered a diagnostic challenge because of the difficulty to extract bacilli from the ocular tissue. However, a detailed medical history and eye examination can be the key to an accurate diagnosis and appropriate treatment of the TB

Aproximación diagnóstica a las uveítis / Uveitis: diagnostic approach

Mujer de 32 años, sin antecedentes epidemiológicos relevantes salvo contacto tuberculoso en la infancia, remitida desde el Servicio de Oftalmología para valorar estudio de enfermedad sistémica. Refiere miodesopsias y disminución de agudeza visual en ambos ojos de varios meses de evolución, acompañados de artralgias y tos seca, sin otra sintomatología extraocular. La exploración oftalmológica muestra agudeza visual de 0,3 en el ojo derecho y 0,4 en el ojo izquierdo. En la exploración de la cámara anterior se observa una uveítis anterior bilateral granulomatosa con discreta inflamación (Tyndall 1+). Se observa vitritis (3+) bilateral, con exudados en banco de nieve y flebitis periférica. La angiografía con fluoresceína no muestra signos de vasculitis central, y la tomografía de coherencia óptica confirma la existencia de edema macular quístico bilateral. La autofluorescencia es normal. ¿Cómo debe ser evaluada inicialmente esta paciente para decidir cuál es el estudio sistémico más adecuado teniendo en cuenta las manifestaciones oftalmológicas?(AU)

A 32 year-old woman was referred from the Ophthalmology Department to rule out a possible systemic disease. Her only past medical history of relevance was a tuberculosis contact during childhood. She complained of floaters and progressive blurring of vision in both eyes for some months, as well as arthralgia and cough. Her visual acuity was 0.3 in the right eye and 0.4 in the left eye. Biomicroscopy showed bilateral anterior granulomatous uveitis (1+ cells). Funduscopy showed bilateral vitritis 3+, snow banking and peripheral phlebitis. Fluorescein angiography did not show central vasculitis, and optical coherence tomography showed bilateral cystoid macular oedema. Fundus autofluorescence was normal. How would you initially assess this patient in order to decide which systemic examination should be performed, bearing in mind the ophthalmological manifestations?(AU)
