Effect of laser spot diameter on the reproducibility of visual field analysis in diabetic patients with upper temporal retinal vein occlusion.

Aim: To evaluate the effect of the laser spot diameter on the reproducibility of the visual field analysis in diabetic patients with upper temporal retinal vein occlusion.

Material And Methods: Thirty-six eyes of 36 consecutive type-2 diabetes mellitus patients with upper temporal retinal vein occlusion who required sectoral retinal photocoagulation (SRP) treatment were enrolled for the study. Patients with a history of previous retinal laser photocoagulation, significant lenticular opacities and those whose perimetric test reliability criteria were low (fixation loss >20% and false-positive or false-negative responses >33%) were excluded from the study.

Menstrual cycle-dependent changes in white-on-white visual field analysis of diabetic women.

Aim: To determine the effect of the menstrual cycle on white-on-white perimetry (WWP) tests of diabetic women.

Subjects And Methods: Left eyes of 129 normally menstruating women (81 type 1 diabetes mellitus (DM) with mild (n = 43) and severe (n = 38) non-proliferative diabetic retinopathy (NPDR), and 48 healthy control females) were included in the study. All subjects underwent complete ocular examination and WWP tests both in the follicular (7-10th day of the cycle) and luteal phases (days 3-7 before the bleeding) of two consecutive menstrual cycles.

Endoscopic transnasal dacryocystorhinostomy and bicanalicular silicone tube intubation.

Purpose: To evaluate the results of endoscopic transnasal dacryocystorhinostomy (ETDCR) combined with bicanalicular silicone tube intubation (BSTI) performed in 49 patients with nasolacrimal canal obstructions secondary to chronic dacryocystitis.

Material And Methods: ETDCR combined with BSTI was applied as a primary procedure in 47 cases, and as a secondary procedure in 2 cases. All patients underwent dacryocystography, and 41 patients underwent radionuclide dacryoscintigraphy before the surgery.

Menstrual cycle dependent changes in blue-on-yellow visual field analysis of young diabetic women with severe non-proliferative diabetic retinopathy.

Purpose: To evaluate menstrual cycle dependent changes on blue-on-yellow visual fields of diabetic women, and to compare the results with those of healthy women.

Methods: Left eyes of 93 normally menstruating women were included in the study, comprising 45 with type-1 diabetes mellitus and severe non-proliferative diabetic retinopathy and 48 healthy controls. All subjects underwent baseline complete ocular examination and achromatic visual field analysis.

The effect of prematurity on tear production.

Purpose: To evaluate the effect of the birth weight and the postconceptional age on the tear production of preterm and term newborn infants and to evaluate the changes in tear production during the first two months of life. SUBJECTS--METHODS: Both eyes of medically stable term and preterm infants were included in the study. Based on postconceptional age and birth weight, we divided preterm infants into three groups.
