Abstract: In this study, changes in Retinal Nerve Fiber Layer (RNFL) within peripapillar zone in patients with diabetic retinopathy that accomplish criteria to receive panretinal photocoagulation are analyzed by TD-OCT (Time Domain-Optic Coherence Tomography) unit. This analysis was transversal retrospective and observational and was done in 46 eyes from 33 patients. According to laser application technique, time since application and day of the study, 4 groups of patients were set: the first with patients with less than 30 days since last laser application and day of study. The second with patients with 180 days since laser photocoagulation; the last two groups received panretinal photocoagulation plus macular selective laser with a TD-OCT performed 30 days (for the third group) and 180 days (the fourth group) after administration of treatment. The clinically significant finding was in comparing the group that received panretinal photocoagulation with TD-OCT after 30 days, and the group that received panretinal photocoagulation and TD-OCT after 180 days. Average thickness was less in the second group, with a statistical significant finding p=0.012 in inferior quadrant. Administer laser photocoagulation makes changes in the structure and function of the retina, and according to references many different results may be possible taking in count the equipment used to apply treatment and to take measurements. The patient must be informed about secondary and adverse effects after the treatmentAbstract: In this study, changes in Retinal Nerve Fiber Layer (RNFL) within peripapillar zone in patients with diabetic retinopathy that accomplish criteria to receive panretinal photocoagulation are analyzed by TD-OCT (Time Domain-Optic Coherence Tomography) unit.

Abstract: This retrospective study was designed to evaluate the efficacy and safety of simultaneous topography-guided PRK plus cross linking for patients with mild to moderate keratoconus and to evaluate the stability of the cone. The patients were evaluated over two years for the progression and stability of the cone by the Allegro Pentacam Oculyzer to assess the changes of corneal curvatures (K readings) and the stability of the cone after the surgery and evaluating uncorrected distance (UDVA) and best corrected (CDVA) visual acuities. The follow-up results showed that UDVA improved from 0.4±0.3 to 0.7±0.1 and CDVA changed from 0.6±0.1 to 0.8±0.1 (P < 0.001). The keratometry value decreased from 44.1±2.2 to 41.4±1.6 D for K1, and from 46.4±2.6 to 43.5±1.7 for K2 (P < 0.001). This combined procedure offers a promising method to stabilize the corneal surface with reducing higher order aberrations so enhancing quality of vision in keratoconus patients.Abstract: This retrospective study was designed to evaluate the efficacy and safety of simultaneous topography-guided PRK plus cross linking for patients with mild to moderate keratoconus and to evaluate the stability of the cone.

Abstract: Congenital nasolacrimal duct obstruction is the blockage of the lacrimal drainage system. It occurs in approximately 5 to 20% of normal newborn infants. A history of tearing and mucous or mucopurulent discharge and recurrent pink eye in a young child should alert the physician to the presence of nasolacrimal duct obstruction. Usually this condition is diagnosed clinically, though there are some investigations for precise diagnosis. Treatment is supportive and non surgical in 90 to 95% of cases, only 5 to 10% patients need surgical intervention. Outcome is good with minimal complications.Abstract: Congenital nasolacrimal duct obstruction is the blockage of the lacrimal drainage system.
