A comparative study between the possible protective role of melatonin versus its combination with adipose derived-mesenchymal stem cells on experimentally induced diabetic retinopathy in adult male albino rats (Histological and immunohistochemical study).

Diabetes mellitus is a metabolic disorder that can cause numerous ocular issues as well as long-term effects. In our study, we evaluate the effect of melatonin on the diabetic retinal alterations in male albino rats to the effect of melatonin combined with stem cells. 50 adult male rats were equally divided into four groups control, diabetic, melatonin, and melatonin plus stem cells.

Scleral Fixation of Single-Piece Foldable IOL Using Double-Flanged Technique.

Purpose: To describe the efficiency and visual results of a new method of transconjunctival intrascleral fixation of single-piece foldable IOL using double-flanged 6/0 prolene suture.

Materials And Methods: Seventeen aphakic eyes of 17 patients without adequate capsular support were involved in this study. Lens was prepared by passing the 6/0 prolene suture in a track in the haptic of single-piece foldable IOL created by 31 g needle.

A Mitomycin C-Sparing Novel Technique for Subscleral Trabeculectomy in Primary Congenital Glaucoma.

Purpose: To evaluate the safety and efficacy of a novel modified subscleral trabeculectomy technique in management of primary congenital glaucoma.

Methods: This study included 25 infants diagnosed of having bilateral primary congenital glaucoma. For each patient, one eye was assigned to undergo subscleral trabeculectomy with trimming of the edges of the scleral bed (group I), while the contralateral eye underwent subscleral trabeculectomy with application of mitomycin C (0.

The impact of catalase and glutathione peroxidase-1 genetic polymorphisms on their enzyme activities among Egyptian patients with keratoconus.

Background: Elevated oxidative stress plays a significant role in pathophysiology of keratoconus (KC). Polymorphisms of the antioxidant enzymes as CAT and GPX-1 might alter their antioxidant enzyme capacities leading to increase in the oxidative damage induced KC.

Aim: To analyze the impact of CAT rs7943316 A/T and GPX-1 rs1050450 C/T single nucleotide polymorphisms (SNPs) on the risk and severity of KC among a group of Egyptian population.
