Swept-source OCT findings in shaken baby syndrome: case report.

BACKGROUND: Our purpose was to document the swept source optical coherence tomography (SSOCT) findings in a patient with Shaken baby syndrome (SBS). CASE PRESENTATION: SSOCT was obtained without sedation in a six-month-old girl with bilateral multilayered retinal hemorrhages due to SBS. It documented vitreoretinal interface abnormalities, including internal limiting membrane (ILM) detachment with retinal traction, in association with other specific changes in the inner and outer retinal layers. Six weeks later, retinal hemorrhages had substantially resolved, and there was optic disc pallor. OCT showed ILM reattachment with release of retinal traction and the development of severe diffuse retinal atrophy involving the fovea. CONCLUSIONS: SS OCT can provide useful information in SBS, revealing a wide variety of vitreoretinal interface, inner, and outer retinal changes not detected by clinical examination. It also may have a prognostic value over follow-up.

Multimodal imaging of torpedo maculopathy with optical coherence tomography angiography.

A 24-year-old woman presented for routine clinical evaluation. Her best-corrected visual acuity was 20/20 and slit-lamp examination of the anterior segment was normal in both eyes. Fundus examination of the left eye revealed a hypopigmented lesion, one disc diameter temporal to the fovea, with a hyperpigmented tail extending temporally from the main lesion, consistent with a torpedo maculopathy. Fundus autofluorescence showed an hypoautofluorescence with hyperautofluorescent border. Swept-source optical coherence tomography (OCT) showed a normal inner retina and a degeneration of the outer retina without retinal cavitation. OCT angiography (OCT-A) of the choriocapillaris layer revealed reverse shadowing caused by the increased transmission from the atrophied outer retina and RPE within the torpedo lesion and attenuation of signal in the area of the temporal hyperpigmentation. The superficial capillary plexus was normal. This case includes a multimodal imaging with OCT-A of torpedo maculopathy in a Tunisian woman. Further reports are required to provide a better understanding of this rare condition.

Intralesional corticosteroid treatment of periocular xanthogranuloma associated with adult-onset asthma.

INTRODUCTION: Adult-onset asthma and periocular xanthogranuloma (AAPOX) is a rare non-Langerhans cell histiocytic disorder. AIM: To describe the periocular clinical findings in a patient diagnosed with AAPOX, treated successfully by intralesional corticosteroids. CASE REPORT: A 40-year-old woman presented with bilateral eyelid swelling and adult-onset asthma. Initial examination revealed bilateral yellow-orange, elevated, indurated, and nonulcerated masses at the upper eyelids. The laboratory data showed high level of IgG. Periocular biopsy samples showed xanthoma cells positive for CD68 and Touton giant cells. The patient received 2 intralesional 40 mg of triamcinolone acetonide with a local control. No complications were noted. COMMENTARIES: AAPOX is characterized by a histiocytic proliferation associated to an adult-onset asthma, systemic lymphadenopathy, salivary gland enlargement and elevated serum levels of IgG. Treatment options vary with no current consensus. Intralesional corticosteroids have been rarely reported in controlling the signs and symptoms of adult-onset xanthogranulomatous disease. Surgery was successful but demonstrated recurrence. Methotrexate has been proposed to treat refractory cases or as a potential corticosteroid-sparing therapy. In this case, intralesional corticosteroid was an effective and safe treatment for eyelid adult xanthogranuloma.
