Unilateral hemorrhagic maculopathy: An uncommon manifestation of hand, foot, and mouth disease.

Hand, foot, and mouth disease (HFD) is a common systemic infection occurring in childhood or immunocompromised adults caused by enteroviruses, the most common being coxsackievirus A16 and enterovirus 71. It is characterized by maculopapular eruptions over the hands and feet and ulcerative stomatitis. Ocular involvement is a rare complication and commonly manifests as inflammatory macular pathology. We report a case of HFD in an immunocompetent adult male with unilateral ocular involvement presenting as hemorrhagic maculopathy and its management with complete anatomical and functional recovery.

Role of anterior segment optical coherence tomogram in Descemet's membrane detachment.

Descemet's membrane detachment (DD) is a rare but serious complication of intraocular surgery. In rare cases where corneal edema is severe and we may not be able to visualize DD on slit-lamp examination, anterior segment optical coherence tomogram (AS-OCT) would be helpful. We describe two patients with DD, highlighting the role of AS-OCT in early diagnosis and management of patients with DD. One of the patients had DD with rolled in edge, which could only be visualized with AS-OCT. In such a situation, AS-OCT can identify the edge of detachment and show the exact position of the rolled edge, which can allow us to plan the surgical strategy to unroll the DD.

Optical Coherence Tomography of Idiopathic Polypoidal Choroidal Vasculopathy

PURPOSE: To characterize cross-sectional images of idiopathic polypoidal choroidal vasculopathy (PCV). METHODS: A cross-sectional and retrospective study was performed involving 28 eyes with PCV and 112 eyes with exudative age-related macular degeneration. The frequency and dimensions of the retinal pigment epithelial detachment (RPED) with attenuation of internal reflectivity on optical coherence tomographic (OCT) examination were compared in both diseases. RESULTS: OCT showed the RPED with attenuation of internal reflectivity corresponding to the polypoidal structure in the indocyanine green angiogram in 75% of eyes with PCV, which was significantly more frequent than in eyes with exudative age-related macular degeneration (3.6%). In lesions suspicious of exudative age-related macular degeneration or PCV, the RPED with attenuation of internal reflectivity on OCT images strongly supported PCV diagnosis with a sensitivity of 84% and a specificity of 94%. The base diameter (p=0.010) and base diameter times height (p=0.028) of RPED were smaller in PCV than in exudative age-related macular degeneration. CONCLUSIONS: An RPED with attenuation of internal reflectivity in OCT examination is a highly sensitive and specific finding which characterizes PCV. Recognition of this RPED appearance, as well as the evaluation of its size, aids in the diagnosis of PCV.
