RESUMEN
The first very important step for the refractive surgery is the selection of the patients, because there are situations when the surgery for reducing the diopters can produce complications which are difficult to solve. The investigation of the patients who come for a refractive surgery has many steps and each step has his importance.

The success of the refractive surgery depends of the absence of the incidents during and after the surgery. Any complication can compromise more or less the result of the intervention and make it inefficient or even injurious.

LASIK after radial keratotomy is difficult and intraoperative risks are high. In this article I present the case of a patient who underwent such an operation.

Due to its objectivity, reproducibility and predictive value confirmed by many large-scale statistical clinical studies, Heidelberg Retina Tomography has become one of the most used computerized image analysis of the optic disc in glaucoma. It has been signaled, though, that the diagnostic value of Moorfieds Regression Analyses and Glaucoma Probability Score decreases when analyzing optic discs with extreme sizes. The number of false positive results increases in cases of megalopapillae and the number of false negative results increases in cases of small size optic discs. The present paper is a review of the aspects one should take into account when analyzing a HRT result of an optic disc with anatomic particularities.

The early diagnosis and detection of progression are two key-elements in the actual management of glaucoma. The current opinion in clinical practice is to quantify the structural damage for a better follow-up of the patient and the standardization of the results. The present review is a concise survey of literature covering the period of 1990-2010, documenting the evidence-based role of confocal scanning laser ophthalmoscopy in glaucoma diagnosis and management.
