Objective
The Watzke-Allen test is a established clinical test, which is applied to examine the neuro retina in the foveolar area. Patients with macular hole usually test positive for it. The OCT III represents an objective method to quantifyof the retinal layers.
Methods
20 patients with funduscopically defined macular hole grade 3 or 4 were tested for Watzke-Allen slit lamp sign. Additionally an OCT of the macula was performed. Evaluation of the OCT took place without clinical knowledge of the patient. We studied the correlation between both tests.
Results
In 18 of 20 patients we found a positive Watzke-Allen test. In 20 of the 20 patients the funduscopic findings of macular hole were confirmed by means of OCT.
Conclusions
The Watzke-Allen test which is easily performed in clinical routine, demonstrates a good anatomical-functional correlation. For individual cases e.g. slightly eccentric location of the macular hole the value of the Watzke-Allen test is however limited.
