Effect of ocular hypotony secondary to cyclodialysis cleft on corneal topography.
OBJECTIVE
To report the changes in corneal topography in 2 cases of ocular hypotony induced by cyclodialysis cleft after blunt trauma, which were successfully treated by argon laser photocoagulation.


METHODS
For both patients, a full ophthalmic clinical examination and corneal topography were performed before and after argon laser cleft closure.


RESULTS
In the first case, the corneal topography showed 3.81-D astigmatism at 96 degrees, which was reduced to 1.1 D at 124 degrees 1 week after treatment and 0.66 D at 122 degrees at 3 weeks after treatment. In the second case, the corneal astigmatism was 3.91 D at 104 degrees, which decreased to 1.44 D at 104 degrees and 0.35 D at 118 degrees at 1 week and 4 months after treatment, respectively.


CONCLUSIONS
In both cases, the with-the-rule astigmatism reduced significantly after successful closure of the cleft and an increase in intraocular pressure.
