PARACENTRAL ACUTE MIDDLE MACULOPATHY ASSOCIATED WITH EOSINOPHILIC GRANULOMATOSIS WITH POLYANGIITIS.

Purpose: To present a case of paracentral acute middle maculopathy (PAMM) associated with transient loss of vision from eosinophilic granulomatosis with polyangiitis (EGPA)-associated ischemic vasculitis.

Methods: Case report and review of the literature.

Results: A 52-year-old man presented with recurrent episodes of amaurosis of the right eye.

Acute effects of caffeine and glucose intake on retinal vessel calibres in healthy volunteers.

Purpose: To evaluate the acute effects of caffeine and glucose intake on retinal vascular calibre of healthy adults.

Methods: This prospective crossover study was conducted at the Centre for Eye Research Australia (Melbourne, Australia). Standardized doses of 300 mg caffeine (approximately 3 cups coffee), 30 g glucose or 300 ml of water, were each given to 19 healthy subjects on separate days.

Choroidal effusion as a manifestation of central serous chorioretinopathy: A case report.

Purpose: To report a case of bullous central serous chorioretinopathy presenting with large choroidal effusions.

Observations: A patient presented with typical features of bullous central serous chorioretinopathy with large choroidal effusions. He had a previous history of bullous central serous chorioretinopathy in his other eye.

Quantitative Analysis of the Ellipsoid Zone Intensity in Phenotypic Variations of Intermediate Age-Related Macular Degeneration.

Purpose: Reduction of the ellipsoid zone (EZ) intensity has been reported in eyes with age-related macular degeneration (AMD). This study determined whether overall EZ intensity, in retinal locations undisturbed by pathologic features, is associated with the presence of clinical features, which are known important phenotypic risk factors for disease progression, large drusen, reticular pseudodrusen (RPD), and pigmentary abnormalities.

Methods: A horizontal B-scan through the foveola on spectral-domain optical coherence tomography (SD-OCT) was performed in both eyes of 75 participants with bilateral intermediate AMD and 10 age-similar control participants.

Spontaneous cutaneous endometriosis of the umbilicus.

Cutaneous endometriosis that arises de novo, without a prior history of surgery, is a rare phenomenon. The clinical diagnosis of cutaneous endometriosis remains challenging due to the variable clinical appearance and symptoms of the condition, and therefore must be considered in the differential diagnosis of any umbilical lesion. We report a 31-year-old woman who presented with spontaneous cutaneous endometriosis of the umbilicus.

Central retinal function as measured by the multifocal electroretinogram and flicker perimetry in early age-related macular degeneration.

Purpose: To determine the retinal function in early age-related macular degeneration (AMD) assessed by the multifocal electroretinogram (mfERG) and flicker perimetry and to seek a relationship between local objective mfERG parameters and subjective flicker perimetry thresholds.

Methods: mfERG and flicker perimetry were performed in 15 patients (15 eyes) with early AMD and 14 controls (14 eyes) of similar age. The mfERG P1 response amplitude density (nV/deg²) and P1 implicit time of the first-order kernel and the flicker thresholds of each concentric ring were analyzed.
