This could be caused an extreme exophthalmus that has rupture both eyes and could be secondary to an infection. Gas bubble disease can lead to eyes rupture as well. Eyes unfortunately do not regenerate but can heal depending on the type of injury (a picture of the lesions would be extremely helpful in your case). Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. Clinical examination should always include a water quality check, even if you have done so already. Water testing should be performed with a quality test kit, measuring NH4, NO2 and NO3. High ammonia levels, PH imbalances may be responsible for these signs. Oxygen concentration and quality of the filters should be determined as well. If water quality is normal, antibiotic treatment is likely to be required. Please discuss these options with your local vet.
