Session: Poster session A

Study on visual acuity and stereopsis, comparated between non surgical specialities residents vs surgical specialities residents. Analyzing outcomes

Introduction: Visual acuity (VA) is the ability of the vision system to perceive, detect or identify special objects

Stereopsis  (St) is the function of the visual system that allows the three-dimensionality of a visual scene to be distinguished with high precision from a disparity.

Methods: A non-experimental, descriptive, observational, cross-sectional study design.

 

80 residents were included and evaluated by the same person, under optimal conditions, in the same room examination, of which 39 are women and 41 are men, of the 80 residents there are 43 studying a surgical specialty and 37 studying a non-surgical specialty.

It was defined as normal VA:  equal or less than 0 on logmar scale, good VA equal or less than .2 on logmar scale and regular VA equal or greater than .3 on logmar scale

Stereopsis: was defined as normal St equal or less than 40 seconds of arc (SoA), regular St a value between 60 to 80 SoA and gross St: a value equal or greater than 100 SoA.

Results:

We are still analyzing the information but here we have some preliminary results.

VA outcomes

Right eye: 71.25% of the persons included in this study has a normal VA result, 23.75% has a good VA and 5% has a regular VA.

Left eye: 71.25% of the persons included in this study has a normal VA result, 21.25% has a good VA and 7.5% has a regular VA.

St outcomes

63.75% of the persons included in this study have normal St,31.25% has a regular St and 5% has gross St.

 

Conclusions

 

We will finish analyzing the information in a time lapse less than 30 days, we have some preliminary conclusions regardless the outcomes.

We believe were going to find a statistic difference about VA and St being better in the surgical residents group.

The measurement of VA is necessary to assess the state of eye health, which is reflected in the general labor law in article 514 (Mexican law).

 

Resident doctors and future specialists have a great dependence on their visual system to be able to train with solid theoretical and practical bases.
