Management of the regression of papilledema with regional axon loss in idiopathic intracranial hypertension patients.

Purpose: To use optic coherence tomography (OCT) to evaluate idiopathic intracranial hypertension (IIH) patients with subclinical segmental optic atrophy despite being under apparently effective treatment.

Methods: IIH patients underwent an OCT examination including the peripapillary retina never fiber layer (RNFL) thickness, ganglion cell complex (GCC) thickness, focal loss volume (FLV) and global loss volume (GLV) of the GCC, and total macular thickness measurements at presentation and at 3, 6, 9, and 12 months after the diagnosis. The obtained data were compared with healthy subjects.

Effects of Topical Ozone Application on Outcomes after Accelerated Corneal Collagen Cross-linking: An Experimental Study.

Purpose: Ozone is a trioxygen molecule that spontaneously degrades into oxygen and oxygen free radicals. This study was designed to assess the effects of topical ozone application on outcomes after corneal collagen cross-linking (CXL).

Methods: Enucleated fresh cadaver yearling sheep eyes ( = 28) were divided into five groups: control (C, = 6), sham (S, = 6), ozone only (Z, = 6), CXL only (X, = 5), and Ozone + CXL (ZX, = 5).

The Effects of Adjuvant Tamoxifen Use on Macula Pigment Epithelium Optical Density, Visual Acuity and Retinal Thickness in Patients with Breast Cancer.

: We aimed to compare best corrected visual acuity, macular pigment optical density and macular thickness in patients with breast cancer, who received oral adjuvant hormone therapy.: We enrolled consecutive eligible patients with breast cancer who were receiving regular medical tamoxifen treatment. The participants were divided into two groups as cases and controls.

The Presence of Conjunctivochalasis in Obstructive Sleep Apnea Patients.

Objectives: The aim of our study was to detect the presence of conjunctivochalasis (CCh) in obstructive sleep apnea (OSA) patients.

Methods: We included 54 subjects (41 OSA patients and 14 control subjects) in the study. All the patients were assessed regarding the presence and stage of CCh.

OCULAR FINDINGS IN A PATIENT WITH ECTODERMAL DYSPLASIA.

Purpose: Ectodermal dysplasia (ED) results from abnormal development of the ectodermal layer. Although coexistence of ED and retinal pathology has been described, concomitance with retinal venous tortuosity has not been reported in the literature.

Methods: Case report.

Changes in the Choroidal Thickness and Axial Length Upon Mannitol Infusion in Patients With Asymmetric Intraocular Pressure.

Background/aims: To evaluate the changes in the choroidal thickness (CT) and axial length (AL) upon systemic mannitol infusion in glaucoma patients with asymmetric intraocular pressure (IOP).

Materials And Methods: Forty glaucoma patients with asymmetric IOP, with the IOP of 1 eye ≥40 mm Hg and the fellow eye <25 mm Hg, were administered 150 mL of a 20% mannitol infusion to reduce the IOP. The CT and AL were measured before and an hour after the infusion.

Association Between Conjunctival and Corneal Calcification and Atherosclerotic Changes in the Carotid Artery in Maintenance Hemodialysis Patients.

Purpose: We aimed to investigate the association between atherosclerotic changes in the common carotid artery (CA) and conjunctival and corneal calcification (CCC) in maintenance hemodialysis (MHD) patients.

Methods: Fifty eyes of MHD patients with the highest CCC scores were enrolled. CCCs were scored according to the method described by Tokuyama et al.

Choroidal Thickness in Patients with Graves' Ophthalmopathy.

Purpose: The purpose of the study is to compare choroidal thickness (CT) in patients with active and inactive Graves' ophthalmopathy (GO) and that in healthy subjects by using spectral domain optical coherence tomography (SD-OCT).

Methods: We conducted an observational, cross-sectional study of 28, 48, and 74 eyes of 14 patients with active GO (group 1), 24 patients with inactive GO (group 2), and 37 age-matched healthy subjects (group 3), respectively. Activity of GO was assessed by using initial clinical activity score (CAS).

Effect of hemodialysis on intraocular lens power calculation.

Background: To evaluate changes in ocular biometric parameters after hemodialysis (HD) in patients with end-stage renal disease (ESRD).

Methods: Forty eyes of 40 patients undergoing HD were included in this cross-sectional study. Keratometry (K) readings, white-to-white (WTW) distance, central corneal thickness (CCT), anterior chamber depth (ACD), pupil diameter, lens thickness (LT), axial length (AL), and intraocular lens (IOL) power calculation were measured with Lenstar LS 900 (Haag Streit AG, Koeniz, Switzerland) before and after hemodialysis.

The Acute Effect of Hemodialysis on Choroidal Thickness.

Objective. To determine the effect of hemodialysis (HD) on choroidal thickness (CT). Methods.

Tear function in patients with chronic renal failure undergoing hemodialysis.

Objectives: To evaluate dry eye symptoms and clinical tear film alterations in patients with chronic renal failure (CRF).

Materials And Methods: Thirty-five non-diabetic CRF patients undergoing hemodialysis, and 31 healthy individuals were enrolled. An ocular surface disease index questionnaire (OSDI) was administered, and after a complete ocular examination, Schirmer and tear break-up time (TBUT) tests were performed.

Assessment of the central corneal thickness and intraocular pressure in premature and full-term newborns.

Purpose: To assess the central corneal thickness (CCT) and intraocular pressure (IOP) in premature and full-term newborns.

Materials And Methods: In this study, we evaluated measurements of CCT and IOP in 45 premature and 45 full-term newborns. IOP was determined with topical anesthesia using a Tono-Pen AVIA, applanation tonometer and a wire lid retractor in premature newborns undergoing screening for retinopathy.

Ophthalmomyiasis externa: three cases caused by Oestrus ovis larvae in Turkey.

Ocular involvement of parasitic infections includes external, internal and orbital ophthalmomyiasis. Oestrus ovis (sheep botfly) is the most common cause of ophthalmomyiasis externa. Living in warm climates, particularly in agricultural districts, is a risk factor.

Impact of intelligent phacoemulsification software on torsional phacoemulsification surgery.

Background: The purpose of this study was to compare phacoemulsification energy parameters during torsional phacoemulsification with or without the use of intelligent phacoemulsification (IP) software.

Methods: One hundred and twenty-eight eyes with nuclear grades ranging from 1 to 5 were enrolled in this randomized prospective study. Operated eyes were divided into two groups, ie, those operated on using IP software (Group 1, n = 67) and those operated on without IP software (Group 2, n = 61).
