Article Synopsis
- The study aimed to assess the safety and effectiveness of the modified Cretan protocol in treating post-laser in situ keratomileusis ectasia (PLE) in 16 patients.
- Results showed that both uncorrected and best corrected visual acuity remained stable after 24 months, with significant improvements in corneal topographic measurements.
- The modified Cretan protocol was deemed safe, with no complications reported, but further research is suggested to validate these findings.
Purpose: To investigate experimentally the effects of Tropifexor, a farnesoid X receptor agonist, on liver injury in rats with obstructive jaundice.
Methods: Forty healthy Wistar albino female rats were divided randomly in selected groups. These groups were the sham group, control group, vehicle solution group, Ursodeoxycholic acid group and Tropifexor group.
Introduction: Developmental dysplasia of the hip (DDH) is a common disorder and associated with significant morbidity of the hip joint. Several risk factors have been identified for DDH. The aim of this study is to investigate whether vitamin D and vitamin D receptor (VDR) levels differ in children with DDH and whether they have an effect on DDH development.

Methods: This prospective and randomized study included 66 eyes of 54 KC patients who received corneal collagen cross-linking treatment and 43 eyes of 32 patients who underwent photorefractive keratectomy due to their refractive error. During surgical procedures, the corneal epithelium was mechanically scraped and gathered to analyze the XO enzyme activity spectrophotometrically.
Purpose: To evaluate visual, refractive, topographic, and aberrometric outcomes of transepithelial phototherapeutic keratectomy (PTK) + corneal collagen crosslinking in the treatment of pellucid marginal degeneration.
Methods: This retrospective study includes 20 eyes of 15 patients with pellucid marginal degeneration treated with transepithelial PTK + accelerated corneal collagen crosslinking. Visual acuity, refraction, topographic keratometry, pachymetry, and aberrations were recorded pretreatment and 6, 12, 24, and 36 months after treatment.
: To evaluate thiol-disulfide homeostasis (TDH) and its relationship with clinical findings in patients with Graves' ophthalmopathy (GO). : This study included 52 patients with GO and 34 healthy controls. Tests of TDH were conducted using the novel automated spectrophotometric method.

Setting: Atatürk Training and Research Hospital, Ankara, Turkey.
Design: Retrospective case series.
Purpose: To compare the 24 month visual, refractive, topographic and aberrometric results of the accelerated and standard corneal collagen cross-linking (CXL) in pediatric keratoconus patients.
Methods: 87 eyes of 64 consecutive keratoconus patients under 18 years old with 24 month follow-up period following standard or accelerated CXL were included. 38 eyes received standard CXL (3 Mw/cm, 30 min), while 49 eyes had accelerated CXL (9 mW/cm, 10 min).
Purpose: To investigate thiol/disulfide status using a novel automated assay in patients with age-related macular degeneration (AMD) compared to age-matched healthy controls.
Methods: A total of 64 AMD patients [51 (79%) non-exudative, 13 (21%) exudative AMD] and 21 age-matched healthy control subjects were enrolled in this study. Plasma total thiol, native thiol, disulfide levels were measured and native thiol/disulfide ratio (TDR) was calculated using a novel spectrophotometric assay.
