A settlement has been reached in the case of a blind Perth man who was taking legal action against his superannuation fund and their insurers, after he was allegedly denied access to his disability insurance benefit.

Mandurah man Stuart Oldham, 33, who requires the assistance of a guide dog, was set to go to court after filing a writ in the WA District Court.

But a settlement between the parties was finally reached over the weekend, just days after the case was exposed publicly by WAtoday.

However, the settlement is confidential and neither Mr Oldham or his lawyers, Maurice Blackburn, can comment on it or the details surrounding it.

Mr Oldham stopped working in 2008 after the total and irrecoverable loss of sight in both eyes and also due a range of other medical conditions, including osteoporosis.

Soon after, he applied to his superannuation fund for the total and permanent disablement benefit he was entitled to under the policy.

The amount he was entitled to was not less than $120,000.

The writ filed in the WA District Court by Mr Oldham's lawyers had alleged the trustee of the super fund - Sunsuper  - and their insurers - Suncorp Life - refused to pay out the total and permanent disablement benefit claimed.

According to the writ, in a letter dated June 6, 2016, Sunsuper and Suncorp Life said while Mr Oldham's "vision was very poor, it was not certain it was permanent."

In an interview with WAtoday before the settlement was reached, Maurice Blackburn lawyer Phil Gleeson said Mr Oldham's case was not isolated.

"It seems inconceivable to us that disability insurance is being denied for a permanent condition, such as blindness, for such an overly technical reason," Mr Gleeson said at the time.

Mr Oldham previously described his eyesight like looking into the sun - without sunglasses on.

"What I see is a blinding white light, I prefer to stay in the darkness if I can, otherwise I get migraines," he said in an interview earlier this month.

"It's quite painful."

The case was expected to be the subject of court ordered mediation within the next three months.

Sunsuper said on Monday "we can confirm that a settlement was made" but so far the company has declined to comment further.
