RESUMEN
BACKGROUND: In recent decades, several studies have found a strong association between prolonged use of video display terminals and ophthalmological symptoms encompassed in the so-called computer visual syndrome (CVS). Few studies have addressed this syndrome in graduate students. METHODS: Observational, cross-sectional descriptive study. A total of 106 postgraduate students were surveyed without ophthalmological pathologies. The diagnosis of CVS was made by means of the questionnaire of Seguí et al. validated in Spanish, which evaluates the frequency and intensity of 16 ocular symptoms. RESULTS: The prevalence of CVS among graduate university students was 62.3% (95% CI: 52.3-71.5). It was found that the highest proportion of students with the syndrome was in the group of older than 40 years old (88.2%) and in the group 21-30 years old (70.0%), showing statistically significant differences (p = 0.004). According to the device and its time of use, students who used the mobile phone for 7-10 h a day showed a higher prevalence of CVS compared to those who used the device for less time (p = 0.030). The business School had the highest prevalence (75.0%). CONCLUSION: Three out of every five graduate students presented CVS with this prevalence being like reported in other populations. There is a need to investigate possible interventions that can help reduce this entity.

RESUMEN
OBJECTIVE: To describe the morphometric characteristics and thickness of the retinal nerve fibre layer (CFNR) in healthy patients using optical coherence tomography. METHODS: A cross-sectional and descriptive study was conducted on a total of 184 eyes of 184 people of mestizo origin enrolled after a complete ophthalmological evaluation at the National Institute of Ophthalmology, Lima-Peru. The morphometric parameters of the optic disc and thickness of the CFNR were measured by optical coherence tomography ZEISS CIRRUS™ HD-OCT Model 5000 (Carl Zeiss Inc., Dublin, CA, EE.UU). Megalopapilla was defined as: area of the optical disc greater than 2.5 mm2 and area greater than the mean plus 2 standard deviations. RESULTS: The areas obtained were: optical disc of 2.21±0.43mm2, neuroretinal ring of 1.37±0.25mm2, 0.84±0.48mm2 cup; mean cup/disc ratio of 0.58±0.16, vertical cup/disc ratio of 0.55±0.15, and a CFNR thickness of 100.30±8.54µm. The prevalence of megalopapilla, being considered as a disc area greater than 2.5mm2 and 3.07, was 24% and 4%, respectively. When comparing megalopapilla with normal discs, the area of the ring (P=.08) and thickness of CFNR (P=.73) did not show statistically significant differences. CONCLUSION: The mean disc area was 2.21±0.43mm2 with a CFNR thickness of 100.30±8.54µm. The prevalence of megalopapilla was 24% and 4%, considering a disc area greater than 2.5 mm2 and 3.07 mm2, respectively. These results show that the megalopapilla and normal discs are similar in terms of ring area and CFNR thickness.
