Safety of various parameter sets with navigated microsecond pulsing laser in central serous chorioretinopathy.

Background: Subthreshold microsecond pulsing laser is an increasingly common treatment approach for central serous chorioretinopathy. However, there is no literature available on the safety of microsecond laser using different fluence settings in this disease. While many publications can be obtained from conventional microsecond pulsing lasers, few parameter sets are published with the navigated microsecond pulsing laser.

Imaging of iris vasculature: current limitations and future perspective.

Fluorescein and indocyanine green angiography have been the traditional ways to image the vasculature of the iris in the last few decades. Because of the invasive nature of these procedures, they are performed in rare situations, and thus, our understanding about iris vasculature is very limited. Optical coherence tomography angiography (OCTA) is a noninvasive imaging method that enables the detailed visualization of the retinal and choroidal vascular networks.

Visual acuity correlates with multimodal imaging-based categories of central serous chorioretinopathy.

Objective: To evaluate visual acuity (VA) and factors influencing VA using new multimodal imaging-based classification of central serous chorioretinopathy (CSCR).

Methods: Retrospective, observational and cross-sectional study on 229 naïve eyes diagnosed as CSCR with available baseline data and multimodal imaging. Each case was classified into (i) simple/complex/atypical; (ii) primary/recurrent/resolved; (iii) persistent or not; (iv) outer retinal atrophy(ORA) present/absent; (v) foveal involvement present/absent; and (vi) macular neovascularization(MNV) present/absent.

Purpose: To determine structural predictors of treatment response in neovascular age-related macular degeneration analyzing optical coherence tomography (OCT)-related biomarkers.

Methods: A retrospective review of patients undergoing treatment for neovascular age-related macular degeneration at a tertiary institute was performed at presentation. High-intensity regimen included eyes on long-term anti-vascular endothelial growth factor treatment with the inability to extend beyond a month without a relapse and needed double the dose of medication (n = 25).

OCT Imaging in Infants.

Optical coherence tomography (OCT) is widely applied in diagnosis and management of retina diseases particularly macular diseases in adult retina practices. However, it has been under-utilized in pediatric retinal diseases especially in neonates and infants. Utilization of OCT in primary macular diseases in this age group is also uncommon and is less reported.

Real-world outcomes of anti-VEGF therapy in treatment-naïve neovascular age-related macular degeneration diagnosed on OCT angiography: the REVEAL study.

Purpose: To compare the 12 months visual and anatomical outcomes of treatment-naïve neovascular age-related macular degeneration (nAMD) patients diagnosed by optical coherence tomography angiography (OCT-A) compared with fluorescein angiography (FA)/indocyanine green angiography (ICGA), after anti-VEGF treatment in a real-world setting.

Methods: Monocentric, observational, parallel-group study of nAMD patients diagnosed with either FA/ICGA or non-invasive OCT-A methods. Patients were treated with a fixed dosing regimen of intravitreal ranibizumab or aflibercept and followed up for 12 months.

Port delivery system: a novel drug delivery platform to treat retinal diseases.

Introduction: Retinal disease treatment delivery is mostly limited to intravitreal injections and slow-release injectable implants due to structural barriers in the eye, and carry associated adverse effects and relatively high treatment burden. The Port Delivery System with ranibizumab (PDS) is a novel drug delivery device that is surgically implanted into the vitreous cavity and allows for continuous release of the anti-vascular endothelial growth factor (anti-VEGF) ranibizumab, eliminating the need for frequent intravitreal injections while maintaining therapeutic intraocular drug levels to control disease activity. Investigations of PDS are summarized in this review.

Intraretinal, sub-retinal, and sub-retinal pigmented epithelium fluid in non-exudative age-related macular degeneration: follow-up with OCT imaging.

Background/objectives: To evaluate the presence and evolution of fluid in non-exudative age-related macular degeneration (AMD) through serial OCT.

Subjects/methods: A retrospective analysis of eyes with non-exudative AMD with a minimum of 4 year follow-up was done. Parameters including intraretinal fluid (IRF), subretinal fluid (SRF), and sub-retinal pigment epithelium (RPE) fluid (SRPEF); subfoveal choroidal thickness (SFCT) and type of drusen were evaluated using optical coherence tomography (OCT) scans at baseline and follow up visits.

Long-term retinal changes in progressive geographic atrophy.

There is no approved antiviral therapy for adenovirus (HAdV) ocular infections. Astodrimer sodium (SPL7013) is a polyanionic dendrimer with antiviral activity. The current study evaluated the ocular tolerability and anti-adenoviral efficacy of topical SPL7013 in rabbit ocular models.

Sildenafil in ophthalmology: An update.

Sildenafil citrate, a selective oral phosphodiesterase 5 inhibitor, is a widely used drug for erectile dysfunction that acts by elevating cGMP levels and causing smooth muscle relaxation. It also has 10% activity against PDE6, a key enzyme in phototransduction cascade in the retina. Recent ocular imaging developments have further revealed the influence of sildenafil on ocular hemodynamics, particularly choroidal perfusion.

related Congenital Stationary Night Blindness in Two Siblings due to Probable Maternal Germline Mosaicism.

: Congenital Stationary Night Blindness (CSNB) is a clinically and genetically heterogenous inherited retinal disorder associated with nystagmus, myopia, strabismus, defective dark adaptation, and decreased vision. Pathogenic variants in at least 17 genes have been associated with CSNB, where a hemizygous variant of causing an X-linked form of the disorder is among the commonest causes.: A retrospective chart review of a single pedigree was performed.

Clinical Practice Guidelines for Occupational Therapists in the Evaluation and Treatment of Oculomotor Impairment Following Traumatic Brain Injury.

Purpose Of Review: Currently, a lack of guidelines exists regarding best practices for occupational therapists (OTs) in the treatment and evaluation of oculomotor dysfunction following traumatic brain injury (TBI). Furthermore, individuals with TBI would benefit significantly from collaboration between OTs and optometrists during inpatient rehab.

Recent Findings: Although few articles examine interdisciplinary models of inpatient rehab care that include optometry, a recent pilot study is explored.

Retinal toxicities of systemic anticancer drugs.

Newer anticancer drugs have revolutionized cancer treatment in the last decade, but conventional chemotherapy still occupies a central position in many cancers, with combination therapy and newer methods of delivery increasing their efficacy while minimizing toxicities. We discuss the retinal toxicities of anticancer drugs with an emphasis on the mechanism of toxicity. Uveitis is seen with the use of v-raf murine sarcoma viral oncogene homolog B editing anticancer inhibitors as well as immunotherapy.

Venous overload choroidopathy: A hypothetical framework for central serous chorioretinopathy and allied disorders.

In central serous chorioretinopathy (CSC), the macula is detached because of fluid leakage at the level of the retinal pigment epithelium. The fluid appears to originate from choroidal vascular hyperpermeability, but the etiology for the fluid is controversial. The choroidal vascular findings as elucidated by recent optical coherence tomography (OCT) and wide-field indocyanine green (ICG) angiographic evaluation show eyes with CSC have many of the same venous patterns that are found in eyes following occlusion of the vortex veins or carotid cavernous sinus fistulas (CCSF).

Brilliant Blue G toxicity in macular hole surgeries: A report on combined phototoxicity and dye-induced macular damage.

Purpose: Vitrectomy with brilliant blue G (BBG) assisted internal limiting membrane (ILM) peeling is the standard operational technique in macular hole surgeries. However, BBG dye, though considered safe and nontoxic, can also occasionally lead to macular toxicity. This study aims to describe the clinical features and characteristics of four eyes who developed macular toxicity after following surgery for macular hole repair.
