Role of hypofractionated stereotactic radiotherapy for primary optic nerve sheath meningioma.

Background: Optic nerve sheath meningiomas (ONSM) are rare tumors potentially causing visual deficits. This study aims to report the anatomic and visual outcomes of patients with primary ONSM treated with hypofractionated stereotactic radiotherapy (HF-SRT).

Methods: Data of 36 patients treated with HF-SRT between 2008 and 2019 were retrospectively collected.

Outcomes and success of amniotic membrane transplantation for the treatment of corneal diseases.

Purpose: The amniotic membrane (AM), the inner layer of the placenta, is a semitransparent, avascular, and thin tissue that is useful due to its structure. Amniotic membrane transplantation (AMT) avoids the need for keratoplasty to prevent corneal perforating. The purpose of the study was to evaluate the visual (gain of or no change in visual acuity) and corneal outcomes (closure of the ulcer or corneal healing) of AMT in patients with ocular surface diseases.

Short-term effect of macular edema on the peripapillary retinal nerve fiber layer in patients with wet age-related macular degeneration and diabetic macular edema: A comparative study.

Background: The combined presence of glaucoma and age-related macular degeneration (ARMD), or glaucoma and diabetes mellitus (DM), occur fairly frequently, especially in elderly patients. This study was intended to compare the effect of resolving macular edema due to DM and wet ARMD on peripapillary retinal nerve fiber layer (RNFL) thickness.

Methods: This cross-sectional study included 76 patients with macular edema secondary to DM (n = 40, 52.

Changes in the Anterior Lens Epithelium and Basement Membrane in Pseudoexfoliation Syndrome undergoing Surgery for Senile Cataracts: A Transmission Electron Microscopic Study.

Objective: To compare the electron microscopic lens findings with and without pseudoexfoliation syndrome (XFS), in patients undergoing surgery for senile cataract.

Study Design: A descriptive study. Place and Duration of the Study: Ophthalmology Department, Hacettepe University Hospital between December 2019 and March 2020.

Periocular apocrine adenocarcinoma presenting as an orbital mass: clinicopathological features and management in four patients.

Purpose: Apocrine adenocarcinoma is a cutaneous adnexal malignancy which can rarely arise from ocular structures. In this retrospective study, we report our experience with four patients who had primary periocular apocrine adenocarcinoma initially presenting with an orbital tumor.

Methods: Data extracted included demographics, clinical, imaging, and histopathological features, and treatment outcomes.

Primary Ciliary Body Marginal Zone Lymphoma Presenting as Hemorrhagic Hypopyon.

Purpose: Our purpose is to report a patient with primary unilateral ciliary body marginal zone lymphoma who initially presented with hemorrhagic hypopyon.

Methods: Retrospective review of the clinical, imaging, and immunohistopathological features of the case was performed.

Results: A 59-year-old man was referred with right anterior uveitis of unknown etiology which was unresponsive to systemic treatment.
