Trophozoites of two Acanthamoeba polyphaga strains (RYD and 435) were readily detached from plastic culture flasks or multiwell plates by 5 min exposure to a detaching fluid containing 0.005% of Triton X-100 and 0.05% ammonium sulphate. This treatment also led to rounding of cells and thus permitted convenient and reproducible counting by either hemocytometer or electronic particle counter. The detaching fluid did not impair viability even after exposure up to 1 h.

Comprehensive multimodal imaging is essential for the precise clinical diagnostics of neovascular age-related macular degeneration (nAMD). Noninvasive optical coherence tomography (OCT) is of prime importance regarding the baseline examination, follow-up and monitoring during treatment. The OCT imaging in nAMD eyes enables a high-resolution assessment of the retinal micromorphology, which can be considerably disturbed in different layers.

Aims: To compare the efficiency of scleral buckling (SB) and pars plana vitrectomy (PPV) with or without SB in patients with primary simple phakic fovea-splitting rhegmatogenous retinal detachment (RRD).
Methods: A retrospective case-control study included 101 patients aged <55 years diagnosed with phakic fovea-splitting RRD. The primary outcome was functional success, defined as achieving a postoperative logarithm of the minimum angle of resolution best-corrected visual acuity of 0.

Purpose: To utilize optical coherence tomography (OCT) and SS-OCT angiography (SS-OCTA) for quantifying morphological changes seen in eyes with recalcitrant neovascular age-related macular degeneration (nAMD) transitioned to intravitreal faricimab injections during the manufacturer's recommended induction phase of treatment.
Methods: Fifty-four treatment-recalcitrant patients (60 eyes) were recruited. OCT and SS-OCTA images were obtained at 0 and 3 months.

Because of its benign nature and rarity, circumscribed choroidal hemangioma (CCH) often receives limited attention, leading to a high rate of misdiagnosis and a lack of standardized treatment protocols. We provide a thorough clarification of the demographics, clinical features, diagnosis, management, and prognosis of CCH. We conducted a systematic search of the PubMed, EMBASE, and Ovid databases up to December, 2023, to identify relevant studies.

: In this study, we evaluated the incidence of cystoid macular edema (CME) after pars plana vitrectomy (PPV) for different retinal pathologies and assessed the role of optical coherence tomography (OCT) biomarkers in guiding treatment decisions in post-surgical CME patients who were refractory to medical therapy over a follow-up period of 12 months. : Medical records of consecutive pseudophakic patients, who underwent PPV for different retinal pathologies, were retrospectively evaluated in this single-center, uncontrolled study. The incidence of post-PPV CME was assessed.
