Evaluation of the Vascular Network with Optical Coherens Tomography Angiography in Multiple Sclerosis and its Relationship with the Clinic.

Introduction: Optical Coherence Tomography Angiography (OCTA) is an examination that is increasingly used in neurodegenerative diseases. This study in multiple sclerosis (MS) patients; It aims to reveal the presence of vascular involvement in the retina and optic nerve and its relationship with disease-related clinical parameters with the help of OCTA.

Methods: One eye of 49 MS patients and 28 healthy controls were included in the study.

Conspicuous Peripheral Retinal Hemorrhages with a Relatively Preserved Posterior Pole in Immune Thrombocytopenic Purpura.

Background: Immune thrombocytopenic purpura (ITP) is a rare auto-antibody mediated disease of isolated thrombocytopenia (<100,000/μL) with normal haemoglobin levels and leukocyte counts. Only a small number of ITP cases have been reported with accompanying ophthalmological findings. Herein, we report an ITP case with demonstrative retinal haemorrhages.

Evaluation of corneal densitometry values with Pentacam in cases of ocular hypertension and pseudoexfoliative glaucoma.

Background: Examination of corneal densitometry measurements using the Pentacam Scheimpflug imaging system in cases of pseudoexfoliative glaucoma (PEXG) and ocular hypertension (OHT).

Methods: The study included 50 eyes of 29 PEXG patients, 25 eyes of 16 OHT patients, and 76 eyes of 38 healthy control subjects followed in the glaucoma clinic. Corneal densitometry values of all cases were measured using the Scheimpflug imaging system (Pentacam, Oculus, Germany).

Macula and optic disc vessel density analyses in systemic lupus erythematosus with optical coherence tomography angiography.

To evaluate the optical coherence tomography angiography (OCT-A) findings in patients with systemic lupus erythematosus (SLE). Twenty-eight eyes of 28 patients with SLE and 27 eyes of 27 age and sex matched healthy controls were enrolled in this cross-sectional study. The vessel densities in the macula and optic disc were evaluated using the OCT-A (Optovue, Inc.

Evaluation of optic coherence tomography findings in patients with inflammatory bowel disease.

Background: Ocular complications are known to appear in inflammatory bowel disease (IBD). Among these, posterior segment complications can lead to substantial morbidity. The aim of the study is to evaluate the retinal nerve fiber layer (RNFL), ganglion cell-inner plexiform layer (GCIPL), and macula thickness measurement in patients with IBD.

The optical coherence tomography angiography findings of rheumatoid arthritis patients taking hydroxychloroquine.

Purpose: The aim of this study is to measure retinal vessel density and thickness of the macula by optical coherence tomography angiography in patients with rheumatoid arthritis taking hydroxychloroquine.

Methods: The study included 40 patients with rheumatoid arthritis taking hydroxychloroquine and 20 age-, gender-, and axial length-matched control subjects. Patients were divided into two groups according to the duration of hydroxychloroquine use.

Chronic Meningitis Complicating Intracranial Hypertension in Neurobrucellosis: A Case Report.

In neurobrucellosis, even though meningitis is encountered frequently, chronic intracranial hypertension is a rare manifestation. Early diagnosis and treatment is very important for the prevention of permanent visual loss secondary to poststasis optic atrophy in these cases. We report a case that presented with permanent visual loss secondary to intracranial hypertension in neurobrucellosis.

Structural and functional comparison of the persistent and resolved amblyopia.

Purpose: To assess structural or functional differences of the retina among subjects with persistent and resolved amblyopia.

Methods: Fourteen eyes with persistent amblyopia that did not reach normal visual acuity (VA) levels (≤0.1 LogMAR) despite amblyopia treatment, 18 eyes with resolved amblyopia, and 16 eyes of 16 normal subjects were included.

Effects of levodopa on retina in Parkinson disease.

Purpose: To evaluate the effects of levodopa on retina, we assessed retina with optical coherence tomography (OCT) in Parkinson disease (PD).

Methods: Thirty-five patients with PD (17 with levodopa monotherapy, 18 untreated) and 11 healthy controls were included in this cross-sectional study. Unified Parkinson's Disease Rating Scale (UPDRS) and Hoehn & Yahr (H&Y) staging scale were used for the evaluation of disease severity.

Bilateral total optic atrophy due to transdermal methanol intoxication.

In this case report, we document a 54-year-old woman with total bilateral optic nerve atrophy after local application of methanol containing spirit. Almost all the reported cases of methanol intoxication in the literature are caused by oral ingestion. In this rare case, we present transdermal absorption of methanol that may cause irreversible blindness in addition to intracerebral lesions.

Nonarteritic anterior ischemic optic neuropathy as the presenting manifestation of primary antiphospholipid syndrome.

Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by vascular thrombosis or pregnancy morbidity. Ocular involvement in APS includes a broad spectrum of manifestations involving anterior and posterior segment or the presence of neuroophthalmologic features. Nonarteritic anterior ischemic optic neuropathy (NAION) is a very rare finding, and in this report a case having NAION as the prevailing sign of APS is presented.
