Predictive factors of long-term visual outcomes after primary Descemet's membrane endothelial keratoplasty (DMEK): retrospective study.

Purpose: To determine predictive factors of higher levels of best-corrected visual acuity (BCVA) in the long-term after primary Descemet's membrane endothelial keratoplasty (DMEK).

Methods: Retrospective, single-surgeon case series of 129 successful primary DMEK eyes without graft failure and with a minimum postoperative follow-up of 12 months. Mixed effect model for repeated measurements (MMRM) analysis was performed to determine recipient, donor, surgical and postoperative factors associated with BCVA ≤ 0.

Surgical approach for management of complete anterior capsular contraction syndrome.

Anterior capsular contraction syndrome is an uncommon but well-known complication associated with continuous curvilinear capsulorhexis performed during cataract surgery. It remains asymptomatic unless the constriction progresses to involve the visual axis or causes late intraocular lens-related complications. A male patient in his 50s presented with severely decreased vision in his right eye 2 years after uneventful cataract surgery.

Outcomes of cystoid macular edema following Descemet's membrane endothelial keratoplasty in a referral center for keratoplasty in Spain: retrospective study.

The aim of this study was to analyze the outcomes of eyes with visually significant cystoid macular œdema (vs-CMO) after Descemet membrane endothelial keratoplasty (DMEK) in a referral center for keratoplasty in Spain. We conducted a retrospective, single-surgeon case series of eyes that developed post-DMEK vs-CMO performed between January 2011 and December 2020. Data collected included: indication for DMEK; biometric data; ocular comorbidities; past medical history; time to detection of vs-CMO after DMEK (T, weeks); best-corrected visual acuity (BCVA, logMAR) and central retinal thickness (CRT, µm) at diagnosis of vs-CMO, after resolution of CMO, and at last follow-up; and management strategy.

Retinal and choroidal thickness changes in systemic lupus erythematosus patients: a longitudinal study.

Background/objectives: To prospectively evaluate changes in peripapillary retinal nerve fibre layer (pRNFL), in all macular layers and in choroidal thickness (CT) in a cohort of systemic lupus erythematosus (SLE) patients without ophthalmologic manifestations. To associate those changes with ophthalmic characteristics, disease activity state, medication and systemic comorbidities.

Subjects/methods: Prospective cohort study of 68 previously diagnosed SLE patients.

Neurodegeneration in systemic lupus erythematosus: layer by layer retinal study using optical coherence tomography.

Background: Systemic lupus erythematosus (SLE) is a chronic, autoimmune and multisystemic disease. Recent studies with functional and structural magnetic resonance imaging and cognitive tests report an unexpectedly high frequency of central nervous system involvement, even in patients with asymptomatic SLE. The purpose of this study was to identify early signs of retinal neurodegeneration by comparing the thickness of the peripapillary retinal nerve fiber layer (pRNFL) and all macular layers between patients with SLE without ophthalmologic manifestations and healthy controls.

Choroidal thickness changes in systemic lupus erythematosus patients.

Purpose: To compare choroidal thickness (CT) between patients with systemic lupus erythematosus (SLE) without ophthalmologic manifestations and a control group. To study the effects in CT of disease duration, activity index, medication and systemic comorbidities.

Methods: Cross-sectional study where spectral-domain optical coherence tomography with enhanced depth imaging was used to measure CT in 13 locations, subfoveally and at 500-µm intervals along a horizontal and a vertical section from the fovea.

The role of ophthalmic imaging in central nervous system degeneration in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune connective tissue disorder that can involve any organ system. Central nervous system involvement can be a severe life threatening complication, ultimately resulting in severe neurodegenerative changes. Magnetic resonance imaging suggests that neurodegeneration, which may have deleterious effects on brain function, may occur early in SLE and experimental models suggest that neuroprotection may be feasible and beneficial.

OCT in Alzheimer's disease: thinning of the RNFL and superior hemiretina.

Background: Peripapillary retinal nerve fiber layer (pRNFL) and internal macular layer thinning have been demonstrated in Alzheimer's disease (AD) with optical coherence tomography (OCT) studies. The purpose of this study is to compare the pRNFL thickness and overall retinal thickness (RT) in AD patients with non-AD patients, using spectral domain optical coherence tomography (SD-OCT) and determine the sectors most characteristically affected in AD.

Methods: A cross-sectional study was performed to determine the pRNFL and overall macular RT thicknesses in AD and non-AD patients, attending a tertiary hospital center.

Choroidal thinning: Alzheimer's disease and aging.

Introduction: The purpose of this study was to measure and to compare macular choroidal thickness (CT) between patients with mild Alzheimer's disease (AD), patients without AD, and elderly patients.

Methods: CT was measured manually in 13 locations at 500-μm intervals of a horizontal and a vertical section from the fovea. Linear regression models were used to analyze the data.

Retina and Choroid of Diabetic Patients Without Observed Retinal Vascular Changes: A Longitudinal Study.

Purpose: To identify changes in choroidal thickness (CT) and all retinal layers of diabetic patients without diabetic retinopathy (DR) after 1 year of follow-up.

Design: Prospective observational cohort study.

Methods: Overall, 125 diabetic patients without DR were included.

Retinal Neurodegeneration in Diabetic Patients Without Diabetic Retinopathy.

Purpose: To compare the thickness of all retinal layers between a nondiabetic group and diabetic patients without diabetic retinopathy (DR).

Methods: Cross-sectional study, in which all subjects underwent an ophthalmic examination including optical coherence tomography. After automatic retinal segmentation, each retinal layer thickness (eight separate layers and overall thickness) was calculated in all nine Early Treatment Diabetic Retinopathy Study (ETDRS) areas.

Punctate Inner Choroidopathy.

Purpose. To report a case of bilateral punctate inner choroidopathy (PIC). Case Report.

The impact of multifocal intraocular lens in retinal imaging with optical coherence tomography.

Multifocal intraocular lenses (MF IOLs) have concentric optical zones with different dioptric power, enabling patients to have good visual acuity at multiple focal points. However, several optical limitations have been attributed to this particular design. The purpose of this study is to access the effect of MF IOLs design on the accuracy of retinal optical coherence tomography (OCT).

Choroidal Thickness in Nonarteritic Anterior Ischaemic Optic Neuropathy: A Study with Optical Coherence Tomography.

Nonarteritic anterior ischemic optic neuropathy (NA-AION) is the most common nonglaucomatous optic neuropathy in adults over 50 years of age. It is usually related to cardiovascular risk factors. The primary objective of this study was to evaluate choroidal thickness in patients with chronic NA-AION, and the secondary objective was to evaluate macular thickness in these patients.

Phacoemulsification versus peripheral iridotomy in the management of chronic primary angle closure: long-term follow-up.

Primary angle closure occurs as a result of crowded anterior segment anatomy, causing appositional contact between the peripheral iris and trabecular meshwork, thereby obstructing aqueous outflow. Several studies highlight the role of the crystalline lens in its pathogenesis. The objective of this work is to compare the long-term efficacy of phacoemulsification versus laser peripheral iridotomy (LPI) in the management of chronic primary angle closure (CPAC).
