Alterations in optical coherence tomography and optical coherence tomography angiography findings in children with partial biotinidase deficiency.

Objectives: The aim of the study was to investigate whether retinal neurovascular structural impairment in children with partial biotinidase deficiency (BD) could be detected early via optical coherence tomography (OCT) and OCT angiography (OCTA).

Methods: Eighty patients with partial BD and 80 control cases without any known systemic or ocular diseases were enrolled in this prospective study. Retinal neurovascular structures in the macular and optic disc regions were examined in using OCT and OCTA.

Intravitreal Ranibizumab Versus Intravitreal Ranibizumab Combined with Posterior Subtenon Triamcinolone Acetonide in Diabetic Macular Edema.

Objectives: This is a retrospective, comparative evaluation of the short-term efficacy and safety of intravitreal ranibizumab (IVR) and IVR combined with posterior subtenon triamcinolone acetonide (STA) in the treatment of diabetic macular oedema (DME).

Methods: A total of 79 pseudophakic eyes of 57 patients with DME who underwent IVR injection treatment were examined retrospectively. All of the patients were treatment-naive.

Evaluating the Reliability and Quality of the Upper Eyelid Blepharoplasty Videos on YouTube.

Purpose: The aim of the study was to assess the quality of videos on YouTube as educational resources for patients and physicians about blepharoplastic surgery.

Methods: This study is a retrospective and cross-sectional study. A YouTube search for the term "blepharoplasty" was made and the first 210 videos were recorded (all video searches were done by clearing all search history without any user login).

The corneal effects of intravitreal dexamethasone implantation.

Objectives: To evaluate the corneal effects of the intravitreal dexamethasone implantation using corneal topography and specular microscopy.

Material And Methods: 27 eyes of the 27 patients who received a single intravitreal dexamethasone implantation dose for diabetic macular edema were enrolled in this study. Sirius topography and EM-3000 specular microscopic examinations were performed at the initial examination (baseline), and then on the first day, during the first week, and 1 month after IDI.

Retinal structural changes in patients receiving tamoxifen therapy by spectral-domain optical coherence tomography.

To evaluate choroidal thickness, ganglion cell complex (GCC) and photoreceptor outer segment (PROS) length were measured in patients with breast cancer undergoing tamoxifen therapy, using spectral-domain optical coherence tomography (SD-OCT); results were compared with those for normal eyes. Forty-four patients with breast cancer, undergoing tamoxifen therapy, and 41 healthy controls were included in this prospective, comparative study. All participants underwent a complete ophthalmologic evaluation and SD-OCT.
