Can optic disc vessel density help in cases of residual disc elevation after shunt surgery in cases of idiopathic intracranial hypertension?

Aim: To detect if we can use the reduction in the optic disc vessel density as an indicator to the reduction in intracranial tension in patients with residual optic disc elevation after shunt surgery as fundus examination in those cases is not conclusive.

Patients And Method: 21 patients with papilledema due to idiopathic intracranial hypertension underwent shunt surgery. Full neurological and ophthalmological assessments were done.

Comparison between open-angle glaucoma and angle-closure glaucoma regarding the short-term optic disc vessel density changes after trabeculectomy.

To compare the microvasculature of the optic disc in open-angle glaucoma (OAG) and angle-closure glaucoma (ACG) after trabeculectomy. This study included 34 patients divided into two groups based on the angle: (1) the OAG Group, which included 24 eyes from 24 patients, and (2) the ACG Group, which included ten eyes from 10 patients. All patients were subjected to comprehensive ophthalmic examinations.

The Effect of Post-Coronavirus Disease 2019 Infection on the Retinal Microvasculature.

Purpose: To evaluate the short-term microvasculature changes of the macula and optic disc following coronavirus disease 2019 (COVID-19).

Methods: This study included 150 eyes (50 eyes of healthy controls and 100 eyes of patients) during the 1 month following COVID-19 recovery, as evidenced by two negative polymerase chain reactions. A complete ophthalmic examination and optical coherence tomography angiography were performed to detect the deep and superficial macular vessel density (VD).

Optic disc vessel density changes after shunt surgery in idiopathic intracranial hypertension.

Aim: To detect the change in optic disc vessel density in patients with idiopathic intracranial hypertension (IIH) after shunt surgery.

Patients And Method: Twenty-one patients with IIH underwent shunt surgery. Patients were subjected to full ophthalmic and neurological examinations.

The effect of various types of COVID-19 vaccines on the retinal microvasculature.

Purpose: To detect the effect of various types of COVID-19 vaccine on macular and optic disc microvasculature.

Method: One hundred subjects receiving various types of COVID-19 vaccine (AstraZeneca, Sinopharm, Sinovac, Pfizer, and Moderna) were included in this study. A complete ophthalmic examination was done which included best-corrected visual acuity measurement, slit-lamp biomicroscopy, intraocular pressure measurement with Goldmann applanation tonometry, and fundus examination.

Comparison between hyaluronic acid filler and botulinum toxin type A in the treatment of thyroid upper eyelid retraction.

Purpose: The aim of this study was to compare between hyaluronic acid filler (HA) and botulinum toxin type A (BTX-A) in the treatment of thyroid upper eyelid retraction.

Study Design: This was a prospective comparative study.

Methods: A total of 50 eyes with upper thyroid eyelid retraction were divided into 2 groups.

The impact of Nd: YAG laser posterior capsulotomy by the use of "the circular pattern with vitreous strand cut" technique on anterior chamber parameters.

Aim: The purpose of this study is to identify the effect of Nd: YAG laser posterior capsulotomy using an anterior chamber morphology.

Methods: This study included 42 eyes of 33 pseudophakic patients with visually significant PCO after uncomplicated cataract surgery. Exclusion criteria were complications related to cataract surgery, corneal pathology, pseudoexfoliation, glaucoma, uveitis, previous ocular surgery or trauma, and posterior segment pathology.
