Idiopathic intracranial hypertension in Omani adults: A tertiary center experience.

Background: To evaluate the clinical profile, risk factors, and ophthalmic diagnostic and monitoring tools in Omani patients with idiopathic intracranial hypertension (IIH) using optical coherence tomography (OCT).

Methods: A retrospective single institutional cohort study on Omani patients with a fulfilled diagnosis of IIH from January 1, 2014, to January 1, 2020, was conducted. The data obtained from the neuro-ophthalmic clinic contained age of onset of the disease, gender of patients, body mass index (BMI), presence of other associated conditions, and medication use.

Effect of fingolimod therapy on quantitative macular changes among patients with relapsing-remitting multiple sclerosis: a four-year follow-up study from Oman.

Purpose: Fingolimod (FTY-720) is an immunomodulatory oral agent approved for the treatment of relapsing-remitting multiple sclerosis (RRMS); however, several clinical trials have shown that some recipients may develop macular oedema (ME) as an adverse reaction. As there are no studies assessing the long-term (> 1 year) effect of fingolimod on the macula, this study aimed to evaluate the quantitative effect of fingolimod therapy on central macular thickness (CMT) and total macular volume (TMV) over a four-year period.

Methods: This retrospective longitudinal cohort study was performed between January 2014 and December 2018.

Ocular adnexal marginal zone lymphoma arising in a patient with immunoglobulin-G4-related ophthalmic disease: A 4-year delay in diagnosis.

Ocular adnexal marginal zone B cell lymphomas (MZBLs) make up the majority of lymphomas arising from the ocular adnexa. Immunoglobulin-G4 (IgG4)-related disease is a recently proposed entity with several unique clinicopathological features, such as enlargement of affected organs, elevated serum IgG4 level, and infiltration with IgG4-positive plasma cells. Ocular adnexal MZBLs are reported to arise in IgG4-related sclerosing dacryoadenitis, indicating a possible link between the two conditions.

Retinal nerve fiber layer thickness in multiple sclerosis with and without optic neuritis: a four-year follow-up study from Oman.

Background: Multiple sclerosis (MS) is an autoimmune disease that attacks the central nervous system, with optic neuritis (ON) being a common early manifestation. Retinal nerve fiber layer (RNFL) thickness may be a biomarker of neuroaxonal damage in MS patients. We sought to evaluate changes in RNFL thickness over 4 years in Omani MS patients with or without ON in comparison to a healthy control group.

Orbital implant exposure following enucleation or evisceration.

Purpose: To study the exposure rate of orbital implant postenucleation or evisceration procedures in two tertiary hospitals in Oman.

Design: A retrospective, descriptive, cross-section study.

Materials And Methods: Patients' records were reviewed for patients' demographics, surgical indications, implant types, follow-up and any reported complications after surgeries.

Visual rehabilitation by scleral fixation of posterior chamber intraocular lenses in Omani children with aphakia.

Background And Objective: To report indications and outcomes of scleral-fixated posterior chamber intraocular lenses (PC IOLs) in Omani children with aphakia.

Patients And Methods: Patients with aphakia who were younger than 16 years, unsuitable for spectacle or contact lens correction, and without capsular support underwent an anterior vitrectomy and 10-0 polypropylene inside-out scleral fixation ofa PC IOL.

Results: Scleral-fixated PC IOLs were implanted in 28 eyes of 24 patients.

Visual rehabilitation by scleral fixation of posterior chamber intraocular lenses in amblyopic aphakic children.

Background/aims: To report on the outcome of scleral fixated posterior chamber intraocular lens (S-IOL) implantation in aphakic amblyopic children after 1 year.

Methods: Amblyopic children with aphakia after traumatic and congenital cataract surgery unsuitable for spectacle or contact lens correction were operated with an anterior vitrectomy and inside-out double thread scleral fixation of an Alcon CZ70BD pcIOL. Refraction and vision was compared after 12 months.
