[Blood group incompatibility as risk of corneal rejection].

Background: There is a high risk of rejection of a corneal transplant known as a “rejection episode” in our Hospital conditioned by multiple variables. The aim of this article is to analyze the different risk factors of “corneal rejection episode” in post-transplant patients at one year of follow-up and in particular to consider the presence of donor blood incompatibility during the first year of post-surgical follow-up.

Methods: A nested case-control study was designed in a cohort: observational, longitudinal, analytical and retrospective from year 2012 to 2013.

[Ocular evisceration etiology].

Background: The aim of this paper was to determine the most common etiology of ocular evisceration in a tertiary-level hospital.

Methods: Observational and retrospective study in the Ophthalmology Department from January 2013 to December 2016 at the Centro Médico Nacional Siglo XXI.

Results: Of the 54 eviscerations, exogenous endophthalmitis was found 25.

[Prognostic category of corneal transplantation in a referal center].

Background: Penetrating keratoplasty is considered the most frequent and successfully performed organ transplantation. Indications of corneal transplantation have changed over time and they vary according to the country. Some risk factors for graft rejection, as age, corneal vascularization or ocular surgery, among others, have been identified.

[Quality of corneal tissue procured by trained non-ophthalmologist medical personnel].

Background: The cornea is the first tissue awaiting transplantation at a national level. It is imperative to train health personnel in procurement technique with excision of corneoscleral button in situ. The objective was to compare the quality of corneal tissue procured by social service medical interns and Ophthalmology residents in a third level hospital.

[Neovascularization corneal regression in patients treated with photodynamic therapy with verteporfin].

Background: Corneal neovascularization is a vision-threatening condition usually associated with inflammatory or infectious disorders of the ocular surface. One current treatment is photodynamic therapy, which uses a photosensitizer to occlude the vessel, is successfully produced microvascular thrombosis with minimal damage to surrounding normal tissue. The aim of this article is to quantitatively determine the percentage of regression of corneal neovascularization experienced by patients treated with photodynamic therapy with verteporfin.
