Background And Objective: Investigations of morphological changes in photoreceptors in Behçet's disease (BD) using adaptive optics scanning light ophthalmoscope (AOSLO) are lacking. The authors aimed to evaluate macular cone density and regularity in BD patients with or without a history of uveitis with good visual acuity (VA).
Patients And Methods: The authors included 16 patients (29 eyes) with BD and 12 healthy volunteers (12 eyes) as controls. All subjects had VA of 20/20 or higher. Subjects underwent AOSLO to evaluate the photoreceptor status including cone density (numbers/mm) and proportion of hexagonal Voronoi domains.
Results: Hyporeflective patches that were not detected in color fundus photograph or optical coherence tomography were observed by AOSLO in BD patients both with and without past uveitis history; these were not detected in the control group. Cone density was significantly reduced in BD patients with a history of uveitis compared to controls ( = .002). The proportion of hexagonal Voronoi domains was significantly reduced in BD eyes both with and without history of uveitis relative to controls ( < .001).
Conclusion: Macular photoreceptor damage was observed in BD patients with and without a history of uveitis. .

Predictors of cytomegalovirus corneal endotheliitis postcorneal transplantation.
Br J Ophthalmol

Department of Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto, Kyoto, Japan.
Purpose: This study was designed to investigate risk factors for the development of cytomegalovirus (CMV) corneal endotheliitis following corneal transplantation.
Methods: We retrospectively analysed 1225 corneal transplants for bullous keratopathy between 2011 and 2021. 31 cases who were administered the treatment of CMV corneal endotheliitis preoperatively were excluded, and 1194 cases were analysed for risk factors for the development of CMV corneal endotheliitis following corneal transplantation.
Automated quantification of anterior chamber cells using swept-source anterior segment optical coherence tomography.
J Ophthalmic Inflamm Infect

Ocular Inflammatory Disease Center, UCLA Jules Stein Eye Institute, Los Angeles, USA.
Purpose: To validate automated counts of presumed anterior chamber (AC) cells in eyes with histories of uveitis involving the anterior segment using swept-source (SS) anterior segment optical coherence tomography (AS-OCT) against manual counts and compare automated counts against Standardized Uveitis Nomenclature (SUN) criteria.
Methods: Eyes were imaged with the ANTERION SS AS-OCT device (Heidelberg Engineering). A fully automated custom algorithm quantified the number of hyper-reflective foci (HRF) in line-scan images.

Ocular toxoplasmosis is the leading cause of infectious retinochoroiditis in both adults and children. It is caused by the obligate intracellular parasite, Toxoplasma gondii. It is a common cause of posterior uveitis and focal retinitis, typically seen in immunocompetent individuals as a primary infection or in immunocompromised individuals as reactivation of latent infection.

- The study investigates risk factors for proliferative vitreoretinopathy (PVR), a common complication after retinal detachment surgery.
- A large patient database was analyzed, identifying systemic (like age, gender, and smoking) and ocular (such as trauma and previous eye conditions) factors that correlate with increased PVR risk.
- The findings emphasize the importance of considering these risk factors in surgical planning and treatment to prevent PVR in patients with retinal detachment.
