Purpose Of Review: The novel coronavirus disease in 2019 (COVID-19) has a wide range of systemic manifestations. Ocular manifestations are now well recognized, with conjunctivitis being the most common. Posterior segment involvement is uncommon and has mainly been described in case reports. This review provides an overview of the posterior segment involvement of COVID-19.
Recent Findings: Severe acute respiratory syndrome coronavirus 2 affects the retina and the choroid through either direct entry or triggering an indirect inflammatory response. Majority of the retinal findings is a result of microvascular derangement leading to cotton wool spots, intraretinal hemorrhages, paracentral acute middle maculopathy, acute macular neuroretinopathy, or retinal vein occlusions. Rarely, inflammation involving the retina or the choroid, or reactivation of previously quiescent uveitis, can be seen.
Summary: It is important to recognize the possible correlation between ophthalmic conditions and COVID-19 as it can aid in diagnosis, management, and mitigation of the disease.

A 64-year-old woman suffered a traumatic rupture of the inferior rectus muscle, with the distal segment unrecoverable. An inferior oblique muscle transposition, augmented with a posterior fixation suture, was performed. This modification may have contributed to the surgical outcome.

Objectives: This study aimed to develop an artificial intelligence (AI)-based deep learning model for the detection and numbering of dental implants in panoramic radiographs. The novelty of this model lies in its ability to both detect and number implants, offering improvements in clinical decision support for dental implantology.
Materials And Methods: A retrospective dataset of 32 585 panoramic radiographs, collected from patients at Sivas Cumhuriyet University between 2014 and 2024, was utilized.

Background: Currently, some novel rods with lower elastic modulus have the potential as alternatives to traditional titanium alloy rods in lumbar fusion. However, how the elastic modulus of the rod (rod-E) influences the biomechanical performance of lumbar interbody fusion remains unclear. This study aimed to explore the quantitative relationships between rod-E and the biomechanical performance of transforaminal lumbar interbody fusion (TLIF).

Background: Adjacent segment disease (ASD) is a degenerative condition at the segment adjacent to a previously fused segment. Potential risk factors for ASD, such as posterior ligamentous complex (PLC) integrity between the upper instrumented vertebra (UIV) and the first unfused segment (UIV+1), have not been addressed. The objective of this study is to assess the PLC integrity between the UIV and UIV+1 following posterior lumbar decompression and fusion (PLDF).

Posterior segment ocular diseases, such as diabetic retinopathy, age-related macular degeneration, and retinal vein occlusion, are leading causes of vision impairment and blindness worldwide. Effective management of these conditions remains a formidable challenge due to the unique anatomical and physiological barriers of the eye, including the blood-retinal barrier and rapid drug clearance mechanisms. To address these hurdles, nanostructured drug delivery systems are proposed to overcome ocular barriers, target the retina, and enhance permeation while ensuring controlled release.
