Role of Tear Osmolarity in Dry Eye Symptoms After Cataract Surgery.

Purpose: To analyze changes in tear osmolarity and the Ocular Surface Disease Index (OSDI) in patients after cataract surgery.

Design: Prospective, observational cohort study.

Methods: setting: Institutional.

[Vitreous cyst: a case presentation].

Case Report: We report a case of a 12-year-old patient who complained about visual disturbances in left eye for 6 months. His visual acuity was 1/0.9, funduscopy in left eye revealed a free-floating cyst in the anterior vitreous.

[HIV retinal vasculitis].

Case Report: We present a case of a 47 year-old woman, infected with human immunodeficiency virus (HIV) diagnosed 5 years ago without receiving any treatment, who had floaters in her left eye. A peripheral retinal vasculitis was discovered and confirmed by an angiography. No source of infection was found, antiretroviral and corticosteroid treatment was given, with a complete resolution of the vasculitis.

[Morphological macular changes after cataract surgery: risk factors].

Objective: To analyze morphological macular changes after uncomplicated cataract surgery and their correlation with age and arterial hypertension.

Methods: Total macular volume (TMV), foveal volume (FOVOL) and foveal thickness (FOV) in patients who had undergone cataract surgery were measured using OCT3 Stratus before surgery, the day after the intervention and one month later. The data were analyzed using SPSS 15.
