The accuracy of the trifocal IOL calculation using equivalent K-readings and total corneal power in different zones.

Purpose: To identify the equivalent K-readings and total keratometry zones that is optimally suitable for calculating the IOL spheroequivalent according to 7 formulas.

Methods: The study included 40 patients (40 eyes) who underwent uneventful femtosecond laser-assisted cataract surgery and refractive lens exchange (RLE) with implantation of a trifocal diffractive IOL (PanOptix, Alcon inc.).

A case of a tumor-like condition in the optic nerve head of a pig.

A tumor-like condition of the optic nerve head of unknown etiology was found in a domestic pig. Clinical and histological manifestations suggest that the unusual tumor-like condition is probably a variant of proliferative optic neuropathy caused by unknown nonspecific damage (perhaps trauma), which was received earlier.

"Wet" transepithelial phototherapeutic keratectomy in the management of persistent epithelial defects in the graft.

Purpose: This study aimed to evaluate the efficacy of "wet" transepithelial phototherapeutic keratectomy (TE-PTK) for treating persistent epithelial defects (PEDs) in the corneal graft following penetrating keratoplasty (PKP).

Methods: This study describes a noncomparative, prospective interventional case series. Patients with post-PKP graft epithelial defects lasting >3 months despite previous treatments with extensive wear soft contact lenses, amniotic membrane transplantation, and tarsorrhaphy were treated with wet TE-PTK.

QUANTITATIVE OPTICAL COHERENCE TOMOGRAPHY ANALYSIS OF RETINAL DEGENERATIVE CHANGES IN DIABETIC MACULAR EDEMA AND NEOVASCULAR AGE-RELATED MACULAR DEGENERATION.

Purpose: To investigate the relationship of the pre-anti-vascular endothelial growth factor (VEGF) retinal tissue area (RTA) and optical density (ODRT) of the retinal optical slice portion located in the central subfield, and their ratio (RTA/ODRT), in the presence of diabetic macular edema or of inraretinal cystic fluid in neovascular age-related macular degeneration, to central retinal thickness and best-corrected visual acuity after anti-VEGF treatment with ME resolution.

Methods: The optical coherence tomography images and medical records of 33 patients (41 eyes) with neovascular age-related macular degeneration, 15 (21 eyes) with diabetic macular edema and 9 healthy individuals (15 eyes) were retrospectively analyzed. RTA, ODRT, and RTA/ODRT were calculated on pre-anti-VEGF B-scan images.

Combination of Navigated Macular Laser Photocoagulation and Anti-VEGF Therapy: Precise Treatment for Macular Edema under Dry Retinal Conditions.

. To compare the controllability of navigated macular laser photocoagulation (MLP) in dry versus edematous retina and validate that pretreatment diagnostic images can be used as basis for navigated MLP after the macular edema (ME) has been resolved. .

Navigated Pattern Laser System versus Single-Spot Laser System for Postoperative 360-Degree Laser Retinopexy.

. To compare three 360°-laser retinopexy (LRP) approaches (using navigated pattern laser system, single-spot slit-lamp (SL) laser delivery, and single-spot indirect ophthalmoscope (IO) laser delivery) in regard to procedure duration, procedural pain score, technical difficulties, and the ability to achieve surgical goals. .

High frequency of latent Chlamydia trachomatis infection in patients with rhegmatogenous retinal detachment.

Aim: To determine the frequency of detection of ocular and extraocular Chlamydia trachomatis (CT) infection in non-high myopes with rhegmatogenous retinal detachment (RRD).

Methods: This was a single-center, nonrandomized, prospective, case-control study. One hundred and four patients were divided into a study group with RRD (n=63) and a control group with traumatic retinal detachment (n=41).

Retro-Mode Scanning Laser Ophthalmoscopy Planning for Navigated Macular Laser Photocoagulation in Macular Edema.

Purpose. To compare treatment areas and navigated macular laser photocoagulation (MLP) plans suggested by retro-mode scanning laser ophthalmoscopy (RM-SLO) image versus optical coherence tomography (OCT) central retinal thickness map and treatment planning among retina specialists. Methods.

Clear Corneal Phacovitrectomy with Posterior Capsulorhexis and IOL Implantation in Management of Selective Vitreoretinal Cases.

Purpose. To describe our technique, clear corneal phacovitrectomy with posterior capsulorhexis (CCPV), for the management of selected posterior segment intraocular foreign body (IOFB), posteriorly dislocated lens fragments (PDLF), and proliferative diabetic retinopathy (PDR) cases. Methods.

Latent Infections as a Risk Factor for Posttrabeculectomy Bleb Failure.

Purpose: To investigate latent conjunctival Chlamydia trachomatis (CT) and Bacteroides fragilis (BF) infections as potential risk factors for posttrabeculectomy bleb failure.

Patients And Methods: This retrospective observational study included 50 primary open-angle glaucoma eyes of 50 patients who were submitted to trabeculectomy without cytostatics from September 2010 to June 2011 and were followed up for at least a year. Preoperatively, conjunctival scrapings were taken and their specimens subjected to polymerase chain reaction, direct fluorescent assay and cell culture testing for CT, and culture for BF on blood agar medium.

High Frequency of Latent Conjunctival C. trachomatis, M. hominis, and U. urealyticum Infections in Young Adults with Dry Eye Disease.

Aim. To determine the frequency of detection of conjunctival C. trachomatis (CT), M.

Chronic ocular Chlamydia trachomatis infection in rabbits: clinical and histopathological findings in the posterior segment.

Purpose: To investigate clinical and histopathologic manifestations of Chlamydia trachomatis (CT)-induced chronic posterior segment (PS) inflammation in rabbits.

Methods: Fifteen rabbits were divided into three equal groups of CT subconjunctival-only (SC) and subconjunctival plus intravitreal (SC+IV) inoculation, and controls. Both noncontrol groups received a bilateral SC injection (BSI) and the SC+IV group additionally received a unilateral IV injection (UII) of CT L2 culture, whereas the controls received a BSI+UII of phosphate-buffered saline.

Midinfrared Laser Pancorneal Coagulation as a Method of Treatment for Painful Bullous Keratopathy.

Purpose: To evaluate the efficacy of midinfrared laser pancorneal coagulation (PCC) for the management of secondary painful bullous keratopathy (PBK) with poor visual potential.

Methods: A single-center, nonrandomized, retrospective observational study was performed on 137 eyes (137 patients) with PBK that underwent midinfrared laser PCC and were followed up in our clinic during 2000 to 2010. Preoperatively and at follow-up visits, all the eyes underwent a standard ophthalmologic examination; concurrently, 36 of these underwent corneal optical coherence tomography (OCT) and Scheimpflug camera examination (SCE).

Vitreoretinal surgery in the management of war-related open-globe injuries.

Background: Ranking among the most severe combat damages, war-related open-globe injuries (WROGIs) are not uniform, so the treatment approaches are sometimes unclear. The essential issue is to define exact indications for time- and resource-intensive vitreoretinal surgery (VRS), known to be an effective procedure for severe posterior segment injuries. We studied WROGI structure, and summarized the experience of specialized ophthalmologic care (SOC) management during local armed conflicts (LACs).
