Acute effects of coffee consumption on the microcirculation of macula and optic nerve head.

This study aimed to evaluate the acute changes in retinal vasculature following coffee consumption. This is an interventional case series. The subjects were 22 healthy young adults.

Acute retinal necrosis. Management and visual outcomes: a case series.

Background: The present study reports the functional and anatomical outcomes of eyes with acute retinal necrosis(ARN).

Methods: This is a retrospective case series conducted at a tertiary Eye Hospital from March 2015 to March 2020. Medical records of patients with clinical and laboratorial-Polymerase Chain Reaction (PCR)-diagnosis of ARN were reviewed.

Response to Comments on 'Acute Bilateral Neuroretinitis and Panuveitis in A Patient with Coronavirus Disease 2019: A Case Report'.

Purpose: to respond to comments on our case report on COVID associated neuroretititis.

Methods: We gathered up to date statistics about the prevalence and incidence of epidemic retinitis in Iran and specifically our region, north-east of Iran.

Results: Our response to Kawal et al comments includes 3 items.

Acute Bilateral Neuroretinitis and Panuveitis in A Patient with Coronavirus Disease 2019: A Case Report.

: Herein, we report a case of bilateral neuroretinitis and panuveitis in a patient recovered from coronavirus disease 2019 (COVID-19).: A 37-year-old male patient with a history of recovered COVID-19, which was confirmed with nasopharyngeal reverse transcriptase polymerase chain reaction (RT-PCR) for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), about one-month ago was referred with one-week history of bilateral severe vision loss. Visual acuity was counting fingers, and bilateral retinitis and panuveitis were revealed in ocular examination.

Long-Term Intraocular Pressure Changes after Pars Plana Vitrectomy: An 8-Year Study.

Purpose: To investigate the long-term changes of intraocular pressure (IOP) after pars plana vitrectomy (PPV).

Methods: This was a retrospective historical cohort study. Patients with a history of vitrectomy in one eye by a single surgeon were enrolled.

Effect of antiglaucoma agents on short-term intraocular pressure fluctuations after intravitreal bevacizumab injections.

Purpose: To evaluate the effect of prophylactic pressure-lowering medications on intraocular pressure (IOP) spikes after intravitreal injections (IVIs) METHODS: In this randomized double-blind clinical trial, 74 eyes that were candidates for intravitreal anti-vascular endothelial growth factor (VEGF) injection (IVI) (0.05 mL, 1.25 mg of bevacizumab) were enrolled and sorted randomly into five groups, group 1: topical timolol 0.

Optical coherence tomography angiography analysis of the retina in patients recovered from COVID-19: a case-control study.

Objective: To quantify the density of the macular microvasculature and the area of the foveal avascular zone (FAZ) in patients recovered from coronavirus disease 2019 (COVID-19) using optical coherence tomography angiography (OCTA) analysis.

Methods: In a comparative cross-sectional, observational study, patients recovered from COVID-19 were included in this study. All included subjects exhibited a reverse transcription-polymerase chain reaction-confirmed diagnosis of COVID-19.

Ocular Manifestations of Hospitalized Patients with COVID-19 in Northeast of Iran.

Purpose: To evaluate ocular findings in patients with Coronavirus Disease 2019 (COVID-19) in the Northeast of Iran.

Methods: In a cross-sectional, observational study all consecutive patients with confirmed COVID-19 diagnosis at the central referral center of these patients in northeast of Iran were included. Ocular examinations (external and slit) were randomly performed for the patients who were admitted to the Intensive Care Unit (ICU) and six COVID wards of the hospital.

Comparison between Tear Film Osmolar Cocentration and Other Tear Film Function Parameters in Patients with Diabetes Mellitus.

Purpose: To evaluate tear film function in patients with diabetes mellitus (DM) using tear film osmolarity (TFO) measurements compared to other tear film function tests.

Methods: DM patients without any history of ocular surface disorder but with potential effects on the tear film were enrolled in this cross-sectional study. Data including dry eye symptoms, duration of DM, stage of diabetic retinopathy and blood hemoglobin A1c levels were recorded.

Effectiveness of Technolas torsional eye tracking system on visual outcomes after photorefractive keratectomy.

Purpose: To investigate the efficacy of Technolas 217Z eye tracking system (torsional component) in corneal surface irregularity and high order aberrations (HOAs) after photorefractive keratectomy.

Methods: Patients with compound myopic astigmatism among persons demanding refractive surgery in Khatam-al-Anbia Eye Hospital with the mean age of 29 years were enrolled in this double-blind randomized interventional study. The mean spherical equivalent (SE) of refractive error was -4.

Effect of oral photochemotherapy (8-methoxypsoralen + UVA) on the electrophysiologic function of retina.

Context: Since we had observed electroretinographic (ERG) abnormalities in some patients undergoing photochemotherapy with normal eye examination, we decided to investigate the effects of this therapy on retinal function.

Objective: To investigate the effects of oral photochemotherapy (8-methoxypsoralen + Ultraviolet-A) on electrophysiologic function of retina.

Materials And Methods: Patients with vitiligo, psoriasis or eczema were enrolled.

Electrophysiologic evaluation of retinal function in patients with psoriasis and vitiligo.

Purpose: To investigate the relation between psoriasis and vitiligo with the electrophysiologic function of the retinal photoreceptors.

Methods: Patients with psoriasis or vitiligo referred for PUVA therapy were enrolled. Complete eye examination was performed.
