Purpose: To report the optical coherence tomographic (OCT) features in eyes with tuberculous choroidal granuloma.
Design: Interventional case series.
Methods: Nine eyes of nine patients with tuberculous granuloma of the choroid were studied using OCT scans.
Results: OCT scan through the lesions revealed a distinctive feature of attachment between the retinal pigment epithelial- choriocapillaris layer and the neurosensory retina over the granuloma ("contact" sign). This was associated with surrounding subretinal fluid and inflammatory infiltrate in the deeper retinal layers.
Conclusions: OCT can be useful in the differentiating choroidal tuberculous granulomas from noninflammatory lesions with a similar clinical appearance.

Cardiothoracovascular Department, Division of Structural Interventional Cardiology, Careggi University Hospital, Florence, Italy.
Background: Lipoprotein(a) [Lp(a)] is associated with increased cardiovascular risk, but its influence on plaque characteristics at optical coherence tomography (OCT) evaluation is not fully understood.
Aims: This study seeks to explore the impact of Lp(a) levels on plaque morphology as assessed by OCT in a very high-risk subset of patients.
Methods: Consecutive patients admitted for acute coronary syndrome (ACS) and undergoing OCT-guided percutaneous coronary intervention (PCI) at a large tertiary care center between 2019 and 2022 were deemed eligible for the current analysis.
Blepharoptosis Associated With the Wearing of Hard Contact Lenses in Keratoconic Eyes.
Cureus

Ophthalmology, International University of Health and Welfare, Chiba, JPN.
Keratoconus is a condition that causes progressive thinning and anterior protrusion of the cornea. Because of its irregular astigmatism, mild to moderate keratoconus is corrected with hard contact lenses (HCLs), but blepharoptosis due to the long-term wearing of HCLs is often a problem. In this study, we investigated blepharoptosis in HCL wearers with keratoconus.

Importance: Capturing high-quality images of the entire peripheral retina while minimizing the use of scleral depression could increase the quality of examinations for retinopathy of prematurity (ROP) while reducing neonatal stress.
Objective: To evaluate whether an investigational handheld ultra-widefield optical coherence tomography (UWF-OCT) device without scleral depression can be used to document high-quality images of the peripheral retina for use in ROP examinations.
Design, Setting, And Participants: This was a prospective, cross-sectional study in the neonatal intensive care unit at a single academic medical center.
Sequential Macular Hole Formation as a Rare Complication of Rickettsia Post Fever Retinitis.

Department of Uveitis and Ocular Immunology Services, Narayana Nethralaya, Bangalore, India.
Purpose: We describe a rare complication of macular hole formation in rickettsia post-fever retinitis.
Patients And Methods: Retrospective observational case report of a patient who presented with post-fever retinitis and cystoid macular edema that later progressed to a macular hole. Clinical record and multimodal imaging including fundus photography, fundus fluorescein angiography (FFA), and spectral domain optical coherence tomography (SD-OCT) were analyzed.

Purpose: To study clinical features, anatomical and visual outcomes in eyes having rhegmatogenous retinal detachment (RD) as the presenting feature of acute retinal necrosis (ARN).
Materials And Methods: We conducted a retrospective cohort study of patients with ARN (active/healed) and concomitant RD at the presenting visit.
Results: The median age of patients was 36 years, with a male preponderance (9:1).
