Intraocular lens power calculation formulas accuracy in combined phacovitrectomy: an 8-formulas comparison study.

Background: Our study aimed to assess and compare the accuracy of 8 intraocular lens (IOL) power calculation formulas (Barrett Universal II, EVO 2.0, Haigis, Hoffer Q, Holladay 1, Kane and PEARL-DGS) in patients submitted to combined phacovitrectomy for vitreomacular (VM) interface disorders.

Methods: Retrospective chart review study including axial-length matched patients submitted to phacoemulsification alone (Group 1) and combined phacovitrectomy (Group 2).

Dril Influences Short-term Visual Outcome after Intravitreal Corticosteroid Injection for Refractory Diabetic Macular Edema.

: Intravitreal injections (IVI) of anti-vascular endothelial growth factor (anti-VEGF) are considered the gold standard for diabetic macular edema (DME). Despite adequate anti-VEGF treatments, many patients present persistent DME. The aim of this study is to identify systemic, ocular and anatomical characteristics influencing functional and anatomical outcomes in refractory DME patients treated with IVI of corticosteroid.

Non-central serous chorioretinopathy in a patient with systemic lupus erythematosus and hydroxychloroquine retinopathy.

Subretinal fluid accumulation in a patient with systemic lupus erythematosus (SLE) may represent a diagnostic challenge. We present a case of a 43-year-old man with baseline diagnosis of SLE and hydroxychloroquine-associated maculopathy who reported progressive vision loss on the right eye, associated with corticosteroids use for an arthritic crisis. Ophthalmological examination did not reveal any acute finding.

VRF-G, a New Intraocular Lens Power Calculation Formula: A 13-Formulas Comparison Study.

Purpose: To compare the accuracy of a newly developed intraocular lens (IOL) power formula (VRF-G) with twelve existing formulas (Barret Universal II, EVO 2.0, Haigis, Hill-RBF 2.0, Hoffer Q, Holladay 1, Kane, Næeser 2, PEARL-DGS, SRK/T, T2 and VRF).

Anterior chamber depth, lens thickness and intraocular lens calculation formula accuracy: nine formulas comparison.

Background/aims: To investigate the influence of anterior chamber depth (ACD) and lens thickness (LT) on 9 intraocular lens (IOL) power calculation formulas accuracy, in patients with normal axial lengths.

Methods: Retrospective case series, including patients having uncomplicated cataract surgery with insertion of a single IOL model, divided into three groups according to preoperative ACD. Each group was further subdivided into three subgroups, according to the LT.

A Review of Neuro-Ophthalmological Manifestations of Human Coronavirus Infection.

Introduction: Human coronavirus (HCoVs) are a group of viruses with recognized neurotropic and neuroinvasive capabilities. The reports on the neurological and ocular findings are increasing day after day and several central and peripheral neurological manifestations are already described. However, none specifically describes the neuro-ophthalmological manifestation of HCoVs.

Retinal structural changes in preterm children without retinopathy of prematurity.

Purpose: The aim of this study was to compare all retinal layers' thickness in full-term and preterm children without retinopathy of prematurity (ROP).

Methods: Cross-sectional study including two groups of patients: group 1 children with history of preterm gestation without ROP (gestational age < 37 weeks) and group 2 healthy children with history of full-term gestation. All subjects underwent an ophthalmic examination including spectral domain-optical coherence tomography.

Long-term results of Descemet-stripping automated endothelial keratoplasty for endothelial failure caused by phakic intraocular lenses.

Purpose: To describe the surgical approach and long-term outcomes of Descemet-stripping automated endothelial keratoplasty (DSAEK) for endothelial failure secondary to phakic intraocular lenses (pIOL).

Methods: Retrospective, interventional case series of 18 eyes of 13 patients who developed endothelial failure secondary to pIOL implant. Patients were submitted to pIOL explant and DSAEK for visual rehabilitation, with or without phacoemulsification plus posterior-chamber intraocular lens implant.

Femtosecond laser-assisted cataract surgery for bilateral anterior lenticonus.

Anterior lenticonus is a characteristic ocular feature of Alport syndrome, leading to progressive vision deterioration. Surgical lens removal may be an option in such cases, and the role of femtosecond laser-assisted cataract surgery (FLACS) has been recently described. Herein, we report the third described case, to our knowledge, of bilateral anterior lenticonus surgically approached through FLACS.

Parainfectious optic neuritis followed by microcystic macular oedema.

Parainfectious optic neuritis is a very rare cause of acute vision loss. We present a case of a 51-year-old man with a recent upper respiratory tract infection, presumably of viral aetiology, who showed up with complains of painless right eye vision loss, followed by the same symptoms on the left eye 3 weeks later. Ophthalmological examination revealed optic disc swelling (sequential in severity) which was confirmed by optic disc imaging.

Bilateral metastases to the extraocular muscles from small cell lung carcinoma.

Bilateral orbital metastases restricted to the extraocular muscles (EOMs) are exceedingly rare. We report a case of bilateral extraocular muscle metastases from a small cell lung carcinoma and provide a review of the relevant literature. A 56-year-old smoker presented with proptosis, motility changes, and a relative afferent pupillary defect of the left eye, with a previous history of a small cell lung carcinoma.

Choroidal binarization analysis: clinical application.

Introduction: Image processing of optical coherence tomography scans through binarization techniques represent a non-invasive way to separately asses and measure choroidal components, in vivo. In this review, we systematically search the scientific literature regarding binarization studies published so far.

Methods: A systematic research was conducted at PubMed database, including English literature articles for all of the following terms in various combinations: binarization, choroid/al, enhanced depth spectral domain/swept source optic coherence tomography, and latest publications up to November 2018 were reviewed.
