[Effect of mitomycin C on corneal regrowth after laser-assisted sub-epithelial keratectomy (LASEK)].

Purpose: To study the effect of mitomycin C (MMC) on the corneal regrowth after laser-assisted sub-epithelial keratectomy (LASEK).

Methods: We performed a prospective, controlled, observer-masked study of 64 consecutive eyes scheduled to undergo LASEK to correct their myopia. The patients were divided into two age-matched groups, with group 1 including 32 eyes in which the ablation depth was ≤ 50 μm and received no MMC.

[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.

[Retinal nerve fiber layer changes after cataract surgery measured by OCT: a pilot study].

Purpose: To analyze changes in peripapillary retinal nerve fiber layer (RNFL) after cataract surgery.

Methods: The average RFNL thickness of patients who underwent cataract surgery was measured using the optical coherence tomography (OCT) III Stratus(R) before surgery, the day after and one month later. The data were analyzed using the SPSS 12.

[Eclipse retinopathy: three case reports].

Case Report: We present the evolution of eclipse retinopathy in 3 patients who came to our hospital after the eclipse of October 2005 and had foveal lesions and visual field alterations.

Discussion: Eclipse retinopathy is a maculopathy that occurs after exposure to intense solar radiation, such as occurs during an eclipse, and is produced by a photochemical mechanism. Although the macular changes and symptoms are usually reversible, residual defects at the level of the EPR and scotoma in visual fields can occur.
