[Morphometry of the optic disc in Togolese patients with glaucoma or suspected glaucoma. Preliminary study].
OBJECTIVE
The aim of this study was to measure morphometric parameters of the optic disc in Togolese glaucoma patients and suspects by the mean of the millimetric scale of the slit lamp and the Goldmann contact lens.


METHODS
We selected 202 patients (393 eyes) with a mean age of 36.69 years +/- 15.33 (standard deviation); they were divided into 2 subgroups A (162 glaucomatous) and B (40 glaucoma suspects); direct reading of the slit lamp millimetric scale and the Goldmann contact lens was used.


RESULTS
In the group A, the optic disc vertical diameter was 1.792 +/- 0.21 mm; the horizontal diameter was 1.701 +/- 0.198 mm. In the group B, vertical disc diameter was 1.700 +/- 0.262 mm; the horizontal one was 1.662 +/- 0.190 mm. The vertical cup disc diameter was 1.147 +/- 0.274 mm in the group A and 0.708 mm +/- 0.274 mm in the group B. The neuroretinal area was 1.360 +/- 0.524 mm2 in group A and 1.786 +/- 0.467 mm2 in group B.


CONCLUSIONS
This study using millimetric scale of the slit lamp and the three mirrors Goldmann contact lens was easy, simple and useful clinically. It could be helpful in conducting quantitative studies in countries with low resources because this method is costless compared with others.
