Melatonin reduces oxidative stress markers and augments anti-oxidant capacity in the rat lens.

The study revealed that peripapillary RNFL is thinner in tha-major in all quadrants and in only the inferior quadrant in IDA. Thinning of the RNLF correlated with hemoglobin value and ferritin level, but not with number of transfusions and visual acuity.

Pterygium is an abnormal fibrovascular tissue extending on the cornea which is a degenerative and hyperplastic disorder. A stromal overgrowth of fibroblast and blood vessels is accompanied by an inflammatory cell infiltrate and abnormal extracellular matrix accumulation. The surgical excision is the main treatment method of pterygium, but recurrence is the most common postoperative complication. In the present study, we aimed to compare the wide conjunctival flap and the conjunctival autografting techniques in pterygium surgery according to time of operation, safety, and effectiveness. Results showed that the effect of wide conjunctival flap techniques on primary pterygium surgery was found close to the conjunctival autograft techniques. In addition, the flap technique has a shorter surgical time, the surgery does not require extreme experience, feeding of the flap is provided with own vessels since the vascular structure is protected on the upper temporal conjunctival area, reverse placement of the flap is not seen, it needs fewer sutures, so that suture disturbances may reduce, and it is less traumatic than autograft technique during conjunctival transport. Therefore, this technique may be preferred in suitable cases.

Patients who previously underwent phaco surgery in one eye experience more pain and have worse cooperation during the other eye phaco surgery.

The ranibizumab-only group and the switching from bevacizumab to ranibizumab group seemed superior to the ranibizumab to bevacizumab group.

The majority of the anterior segment parameters were found to be different in children with Down syndrome. While pupil size, corneal thickness, corneal volume and corneal curvature in DS were less than normal, iridocorneal angle, anterior chamber depth and anterior chamber volume were close to controls. The most important parametric differences in children with DS were seen on the cornea.
