Pituitary Apoplexy Secondary to Thrombocytopenia due to Severe Acute Respiratory Syndrome Coronavirus 2 Infection: Report of a Rare Case and Literature Review.

Purpose: To report a 16-year-old female patient with pituitary apoplexy in the setting of coronavirus disease 2019 (COVID-19) infection-related thrombocytopenia in the absence of preexisting pituitary macroadenoma.

Methods: The patient had been admitted because of respiratory complications of COVID-19 infection and developed thrombocytopenia, intense headache, and symptoms of cavernous sinus syndrome.

Results: Urgent magnetic resonance imaging of the brain depicted a pituitary apoplexy.

Transient intraocular lens opacification during phacoemulsification surgery.

Purpose: To report an interesting case of intraoperative opacification of intraocular lens (IOL).

Methods: This study is a report of a 61-year-old male patient who suffered from nuclear sclerosis cataract and had undergone phacoemulsification surgery. During surgery, intraoperative opacification of IOL (Cristal, Cristalens), which was a foldable, 13 mm, one piece, square edge and hydrophilic acrylic IOL, occurred.

Comparison of Scheimpflug and swept-source anterior segment optical coherence tomography in normal and keratoconus eyes.

Purpose: The purpose of the study was to assess the agreement of anterior segment optical coherence tomography with its older well-known opponent i.e., Sheimpflug imaging in evaluation of the cornea in normal and keratoconus subjects.

Intravitreal Diclofenac plus Bevacizumab versus Bevacizumab alone in treatment-naive diabetic macular edema: a randomized double-blind clinical trial.

The aim of this study is to evaluate the short-term effects of a single intravitreal injection of 1.25 mg Bevacizumab combined with 300 lg/0.1 mL Diclofenac (IVB/D) versus 1.

Preventive effect of vitamin D3 supplementation on conversion of optic neuritis to clinically definite multiple sclerosis: a double blind, randomized, placebo-controlled pilot clinical trial.

Multiple sclerosis (MS) presents with optic neuritis (ON) in 20 % of cases and 50 % of ON patients develop MS within 15 years. In this study, we evaluated the preventive effects of vitamin D3 administration on the conversion of ON to MS (primary outcome) and on the MRI lesions (secondary outcome) of ON patients with low serum 25 (OH) D levels. Thirty ON patients (15 in each of 2 groups, aged 20-40 years) with serum 25 (OH) D levels of less than 30 ng/ml were enrolled in a double blind, randomized, parallel-group trial.

Anti-aquaporin-4 IgG in Patients Presenting with Unilateral Optic Neuritis: A Cohort Study.

Background: Optic neuritis (ON) can be the first presentation of multiple sclerosis (MS) or neuromyelitis optica (NMO). Anti-aquaporin-4 IgG (AQP4 IgG) is a highly specific and moderately sensitive biomarker for NMO. This study was designed to assess the rate of seropositivity for AQP4 IgG, and the short-term outcome of patients presenting with single isolated ON (SION).

Urbach-wiethe syndrome and the ophthalmologist: review of the literature and introduction of the first instance of bilateral uveitis.

Patients suffering from Urbach-Wiethe syndrome (UWS), also known as lipoid proteinosis or hyalinosis cutis et mucosae, may have an ophthalmologist involved in the diagnosis and management of their disease. Along with moniliform blepharosis as a pathognomonic feature of the disease, an ophthalmologist may encounter other manifestations of UWS in any part of the eye such as cornea; conjunctiva; sclera; trabecular meshwork; iris/pupil; lens and zonular fibers; retina; nasolacrimal duct. This paper provides a review on the pathogenesis and the diverse ocular manifestations seen in UWS patients.
