Perifoveal exudative vascular anomalous complex (PEVAC).

We present three cases of patients aged 66, 80 and 23, who presented unilateral vision loss. Optical coherence tomography (OCT) in all of them showed macular oedema and a rounded lesion with hyperreflective wall, and fluorescein angiography (FAG) in two of them showed hyperfluorescent perifoveal aneurysmal dilations with exudation. None of the cases showed response to treatment after one year of follow-up, finally being diagnosed with Perifoveal Exudative Vascular Anomalous Complex (PEVAC).

Two case reports of acute zonal occult outer retinopathy (AZOOR): Importance of multimodal diagnosis.

A presentation is made of two cases of acute zonal occult outer retinopathy (AZOOR); one a young man of 19 years, and the other a 42-year-old woman. The young man complained of unilateral scotoma and photopsia. The woman presented with bilateral visual loss and photopsia. Multimodal imaging, including fundus photography, fluorescein angiography, fundus autofluorescence, spectral-domain optical coherence tomography, and visual field testing, supported the diagnosis of AZOOR. The differential diagnosis is complicated, since it has clinical features in common with other retinopathies. This means that it is essential to use modern imaging tests, especially those where the characteristic trizonal pattern is shown, such as in autofluorescence and OCT.

Chronic cytomegalovirus necrotizing retinitis in a patient with scleroderma and mixed connective tissue disease.

The case is presented of a 52-year-old woman with scleroderma, mixed connective tissue disease, and interstitial lung disease, who developed chronic cytomegalovirus necrotizing retinitis while on treatment with prednisone, mycophenolate, and hydroxychloroquine. Initially diagnosed as macular hole, the patient underwent a pars plana vitrectomy. Two months after surgery, due to progressive worsening, the diagnosis was made and treatment started (intravenous and intravitreal ganciclovir). The patient developed severe macular atrophy with final visual acuity of counting fingers. A chronic retinal necrosis can be caused by cytomegalovirus infection in non-HIV patients with partial immune dysfunction from other causes, characterized by a slowly progressive granular retinitis with occlusive vasculitis.

Multifocal presentation in 2 cases of unilateral acute idiopathic maculopathy. / Presentación multifocal en 2 casos de maculopatía unilateral aguda idiopática.

Two cases of multifocal unilateral acute idiopathic maculopathy are presented, one in a 24 year-old man, and another in a 37 year-old woman. Both of them presented with acute vision loss and clinical findings compatible with unilateral acute idiopathic maculopathy. As a relatively uncommon finding, they had multifocal lesions around a larger central lesion. They experienced a spontaneous improvement of their vision. Atypical presentations of unilateral acute idiopathic maculopathy like multifocal lesions are possible. Ophthalmologists should be aware of this rare form of presentation.

Peripapillary pachychoroidopathy. / Paquicoroidopatía peripapilar.

A study was made on 8 eyes of 5 patients between 47 and 65 years of age with peripapillary pachychoroidopathy. They all presented with a serous detachment of the neuroepithelium or retinal pigment epithelium in the nasal macular region that extended to the optic disc, with an increase in choroidal thickness at that level. An analysis was made of the choroidal thickness using high penetration optical coherence tomography, as well as their outcome in a period between 12 and 48 months. Peripapillary pachychoroidopathy is a distinct variant of the pachychoroid disease spectrum. It must be distinguished from other disorders, such as inflammatory or neuro-ophthalmological conditions, that may manifest in the vicinity of the optic disc. When faced with a patient with suspected pachychoroidopathy, a specific study of the papillary area should be considered using high penetration optical coherence tomography.
