Quantification of Metal(loid)s in Lubricating Eye Drops Used in the Treatment of Dry Eye Disease.

The aim of the study was to evaluate the presence of metal(loid)s in lubricating eye drops used in the treatment of dry eye disease. The concentrations of Al, As, Ba, Cd, Co, Cu, Cr, Pb, Fe, Mg, Mn, Mo, Ni, Se, V, and Zn were determined in 19 eye drop samples using inductively coupled plasma optical emission spectrometry (ICP OES). The limit of detection (LOD) and limit of quantification (LOQ) values for the quantified elements ranged from 0.

Topical Brazilian propolis improves corneal wound healing and inflammation in rats following alkali burns.

Background: The objective of this study was to investigate the effects of the Brazilian Scaptotrigona sp propolis, a widely used folk medicine, in corneal wound healing and inflammation.

Methods: Corneal epithelial defects of 1 mm in diameter were made in the right eyes of Wistar male adult rats by cauterization with silver nitrate sticks. Subsequently, they were divided in two groups (n = 40 rats/group): Brazilian propolis (BP) group was topically treated with a microemulsion containing 1% Brazilian propolis; vehicle (VH) group received the same formulation without propolis.

Preoperative Nd:YAG laser anterior capsulotomy in white intumescent cataracts: report of 11 cases.

Creating a continuous curvilinear capsulorhexis in eyes with white intumescent cataracts is a challenge due to the high risk of extension of capsular tears to the lens periphery. Several approaches have been described to avoid this complication and preoperative Nd:YAG laser anterior capsulotomy has been little reported as an optional technique. Eleven patients with white intumescent cataracts were submitted to preoperative Nd:YAG laser anterior capsulotomy.

Effect of eyelid saccades on the position of lateral canthus in young and older subjects.

Purpose: To measure the effect of down and upgaze on lateral canthus height.

Methods: Observational study. The lateral canthus height of 125 eyes was quantified in the primary position, up, and downgaze.

[Efficacy and low cost in keratoconus treatment with rigid gas-permeable contact lens].

Purpose: To study the efficacy of rigid gas-permeable contact lens (RGPCL) fitting in keratoconus patients and to determine treatment costs.

Methods: The records of 126 patients treated at the Hospital das Clínicas de Ribeirão Preto from January 2001 to June 2002 were retrospectively studied. Information about sex, age and treated eyes was collected.
