Early subclinical macular disease in asymptomatic patients with primary antiphospholipid syndrome: A quantitative multimodal retinal evaluation.

Purpose: To perform a quantitative multimodal evaluation in 25 patients with primary antiphospholipid syndrome (PAPS) without ocular complaints and to compare them with 25 healthy individuals.

Methods: A structural and functional ophthalmological evaluation using optical coherence tomography angiography (OCTA) and microperimetry (MP) exam in 25 patients with PAPS, followed at a tertiary rheumatology outpatient clinic, was performed. All ophthalmologic manifestations were documented and subsequent statistical analysis was performed for comparative purposes, with significance set at < 0.

Structural effects of intraretinal cysts on outer retinal layers in eyes with diabetic macular edema.

Background: Diabetic macular edema (DME) is the main cause of visual loss in individuals with diabetic retinopathy (DR). This study aims to investigate the effects of central macular intraretinal cysts on the underlying outer retinal layer (ORL) in patients with diabetic macular edema (DME).

Methods: In this retrospective and cross-sectional study, diabetic patients with or without DR were categorized into three groups: without DME (group 1), with DME but without any cyst featuring a plateau in the lower region (group 2), and patients with cyst featuring an inferior cyst plateau (group 3), defined as a flat conformation at its posterior aspect.

Optic disc edema and visual loss from paracentral acute middle maculopathy mimicking optic neuritis.

Optic neuritis is an important cause of unilateral and acute visual loss in young adults, but other differential diagnoses should be considered, especially when the disease has an atypical presentation. This report presents the case of a young woman with reduced visual acuity in her right eye, associated with optic disc edema and a relative afferent pupillary defect, that was initially misdiagnosed as optic neuritis and subsequently found to have paracentral acute middle maculopathy, possibly secondary to subtle impending central retinal vein occlusion. This case emphasizes the need to remember that retinal vascular diseases can occasionally mimic optic neuritis.

Assessment of ganglion cell complex thickness and its correlation with retinal sensitivity using microperimetry 6 months after epiretinal membrane surgery.

Purpose: To verify the correlation between the full-macular and the ganglion cell complex (GCC) thickness measurements and retinal sensitivity (RS) assessed by microperimetry (MP) 6 months after surgical peeling for idiopathic epiretinal membrane (ERM).

Methods: Forty-three were submitted to pars-plana posterior vitrectomy (PPV) with concomitant peeling of internal limiting membrane (ILM) for idiopathic ERM treatment. Best-corrected visual acuity (BCVA) and 3D volumetric high-definition optical coherence tomography (OCT) imaging were preoperatively acquired.

OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY BIOMARKERS AND MICROPERIMETRY FEATURES IN BEHÇET'S UVEITIS.

Purpose: To evaluate the parafoveal macular microvasculature and the macular function in patients with retinal vasculitis associated with Behçet's uveitis.

Methods: In 14 patients with inactive Behçet's uveitis and 26 control individuals (13 with nonocular Behçet's syndrome and 13 healthy subjects), we analyzed the retinal nerve fiber layer, ganglion cell layer, full retinal thickness, foveal avascular zone area and sectorial parafoveal vascular density in the superficial vascular plexus, intermediate capillary plexus, and deep capillary plexus using SPECTRALIS optical coherence tomography (OCT) 2 and OCT angiography. Macular sensitivity was analyzed using an MP-3 microperimeter.

Paracentral Acute Middle Maculopathy Associated with Severe Anti-Mog (Myelin Oligodendrocyte Glycoprotein)-Positive Optic Neuritis.

Retinal complications in patients with inflammatory optic neuritis (ON) are generally related to post-infectious neuroretinitis and are considered uncommon in autoimmune/demyelinating ON, whether isolated or caused by multiple sclerosis (MS) or neuromyelitis optica spectrum disorder (NMOSD). More recently, however, cases with retinal complications have been reported in subjects positive for myelin oligodendrocyte glycoprotein (MOG) antibodies. We report a 53-year-old woman presenting with severe bilateral ON associated with a focal area of paracentral acute middle maculopathy (PAMM) in one eye.

Ocular retinal findings in asymptomatic patients with antiphospholipid syndrome secondary to systemic lupus erythematosus.

The objective is to perform a multimodal ophthalmological evaluation, including optical coherence angiography (OCTA), asymptomatic APS secondary to SLE (APS/SLE), and compare to SLE patients and control group (CG). We performed a complete structural/functional ophthalmological evaluation using OCTA/microperimetry exam in all participants. One hundred fifty eyes/75 asymptomatic subjects [APS/SLE (n = 25), SLE (n = 25), and CG (n = 25)] were included.

Normative data for macular perimetry using the MP-3 microperimeter in healthy individuals.

Purpose: Microperimetry has been used for several years as a form of visual function testing in patients with retinal diseases. Normal microperimetry values obtained with microperimeter MP-3 have not yet been fully published, and baseline values for topographic macular sensitivity and correlations with age and sex are needed to establish degrees of impairment. This study aimed to determine values for light sensitivity thresholds and fixation stability using the MP-3 in healthy individuals.

A standardized method to quantitatively analyze optical coherence tomography angiography images of the macular and peripapillary vessels.

Background: Optical coherence tomography angiography (OCTA) is a relatively new non-invasive imaging technique to evaluate retinal vascular complexes. However, there is still a lack of standardization and reproducibility of its quantitative evaluation. Furthermore, manual analysis of a large amount of OCTA images makes the process laborious, with greater data variability, and risk of bias.

Ocular findings in asymptomatic patients with primary antiphospholipid syndrome.

Background: Primary antiphospholipid syndrome (PAPS) is characterized by the presence of antiphospholipid antibodies (aPL), repetitive fetal loss, and arterial/venous thrombosis and no association with other autoimmune rheumatic disease. Ocular involvement can also occur including retinal vascular thrombosis and neuro-ophthalmological manifestations, such as optic neuropathy and amaurosis fugax. Early detection of ocular changes is crucial to minimize functional loss.

Morphofunctional evaluation of peripapillary retinoschisis associated with myopic posterior staphyloma and hyaloid traction: does it cause peripapillary vitreoretinal traction?

This case report presents the details of a 33-year-old female patient who was referred to a specialized retina service because of mild vision loss in her right eye). The patient's visual acuity was 20/25 in right eye and 20/50 in the left eye (; amblyopic); the spherical equivalent was -12.75 diopters (right eye) and -14.

Choroidal Thickness in Eyes with Band Atrophy of the Optic Nerve from Chiasmal Compression.

Background: The choroid is a vascular tissue that helps maintain retinal and prelaminar optic nerve head function. Choroidal thickness has been previously studied in diseases accompanied by retinal neural loss, but the relationship between the two sets of measurements is not clear. In eyes with temporal hemianopia as a result of chiasmal compression lesions (CCL), retinal neural loss tends to be greater in the nasal than the temporal hemiretina, a fact that may be useful in evaluating the effect of inner retinal layer loss on choroidal thickness.

Spontaneous closure of degenerative lamellar macular hole with epiretinal membrane proliferation.

Background: To describe the spontaneous closure of a degenerative lamellar macular hole with epiretinal proliferation (LHEP) as documented with tracked spectral domain optical coherence tomography (SD-OCT).

Case Presentation: A 54-years-old diabetic female patient presented with progressive vision loss in the left eye. SD-OCT illustrated LHEP associated with cystic fluid in the outer nuclear layer.

Unilateral papilledema and peripapillary polypoidal choroidal vasculopathy as the presenting manifestations of intracranial hypertension.

We have reported here the case of a 54-year-old woman with intracranial hypertension that presented with the unique features of unilateral papilledema and peripapillary polypoidal choroidal vasculopathy. Our investigations lead to the diagnosis of idiopathic intracranial hypertension and an incidental small right frontal meningioma. The patient was accordingly treated with oral acetazolamide, followed by three consecutive monthly intravitreal injections of bevacizumab, which resulted in the inactivation of the polypoidal choroidal vasculopathy, marked reduction of lipid exudation, and complete absorption of the subretinal fluid.
