Challenges in the diagnosis and management of atypical fungal keratitis during the COVID-19 pandemic: a case series.

Fungal keratitis is a time-sensitive ocular infection that often requires a high index of suspicion followed by intensive medical/surgical interventions to achieve a successful clinical outcome. COVID-19 pandemic-related restrictions, necessitated the modification of conventional protocols and guidelines associated with the treatment of keratomycosis. We report four cases of atypical fungal keratitis with poorly differentiated clinical characteristics.

Short-Term Efficacy of Selective Laser Trabeculoplasty in Omani Eyes with Glaucoma: A Single Institutional Study.

Purpose: There is some evidence suggesting a different nature of response to selective laser trabeculoplasty (SLT) among different races. Therefore, we aimed to assess the short-term efficacy, safety and nature of outcome of SLT in Omani eyes.

Patients And Methods: A retrospective review was performed of patients with open-angle glaucoma (OAG) or ocular hypertension (OHTN) who underwent a single session of 360-degree SLT between January 1, 2017 and December 31, 2018.

Fibrous histiocytoma as first presentation in systemic lupus erythematosus and sero-positive Sjögren's syndrome.

Purpose: To describe a triad of fibrous histiocytoma, Systemic Lupus Erythematosus and Sero-positive Sjögren's Syndrome.

Observations: This case was diagnosed first as bilateral fibrous histiocytoma of cheeks, which on further investigations proved to be a triad of Systemic Lupus Erythematosus, Fibrous histiocytoma and Sero-positive Sjögren's Syndrome.

Conclusions And Importance: Association between fibrous histiocytoma, Systemic Lupus Erythematosus and Sero-positive Sjögren's Syndrome has been known before, but fibrous histiocytoma as first presentation in the triad has not been reported.

Immunoglobulin G4-Related Disease: An Update.

Immunoglobulin G4-related disease (IgG4-RD) is an increasingly recognized immune-mediated condition comprised of a collection of disorders that share specific pathological, serological, and clinical features. IgG4-RD is a fibroinflammatory condition with a tendency to form tumors with inflammatory infiltrate with IgG4 rich plasma cells and elevation of serum IgG4, which may affect virtually every organ and tissue. IgG4-related ophthalmic disease may present as dacryoadenitis, myositis, or involvement of other orbital tissue.

Visual field defects in non-functioning pituitary adenomas.

Purpose: To report the prevalence and pattern of visual field loss in non-functioning pituitary adenomas and to study the relationship between the tumour size and severity of field defects.

Methods: Ninety-three patients with histologically confirmed pituitary adenomas, non-functional on hormonal assessment, underwent a complete ophthalmic assessment and automated perimetry using the HFA 30-2 programme. Defects with quadrantanopic or hemianopic characteristics, defined using criteria on the threshold/pattern deviation plots were considered typical.
