Secondary glaucoma

Secondary glaucoma may refer to any form of glaucoma where there is a recognized cause of increased pressure within the ocular, resulting in optic nerve damage and loss of vision.

As with the primary form of glaucoma, secondary glaucoma may be of the closed or open-angle type, and may also occur in one or both eyes.

Causes of secondary glaucoma

Secondary glaucoma is a relatively rare form of glaucoma, so it is not known yet why the channels are draining the fluid from the eye stop working by increasing the pressure in the eye. However, it can be assumed that the cause of secondary glaucoma may be:

  • trauma to the eye,
  • rubeosis – abnormalities in the blood vessels inside the eye resulting from diabetes, venous or arterial blockage inside the eye, weak flow in the carotid arteries – in this form of glaucoma is aggressive and almost always requires multiple surgical procedures,
  • pseudoexfoliation – manifested by white deposits on the lens, iris and drainage channels inside the eye and can be associated with glaucoma which progresses very quickly,
  • pigment glaucoma – when the iris is rubbed against the eye lens removing pigment of the eyes, which then blocks the drainage channels, contributing to the formation of glaucoma,
  • surgery associated with the unveiling of the retina with silicone oil increases the risk of glaucoma,
  • inflammatory conditions – chronic inflammatory eye conditions can help glaucoma develop, both due to scarring on the drainage channels as well as in response to the frequent use of steroid droplets,
  • other.

Each of these cases of secondary glaucoma requires an individualized treatment plan.

Symptoms of secondary glaucoma

Depending on the cause (both associated with the eyes as well as a health problem in the body) the emergence of secondary glaucoma may not demonstrate any signs of, or be related to various symptoms:

  • photophobia,
  • tearing eyes appearing repeatedly,
  • the appearance of gloom or rainbow wheels when looking at the sources of light,
  • vision problems in the dark,
  • eye pain, often very strong,
  • nausea, abdominal pain, vomiting,
  • headaches just above the eyebrow radiating in the back of the head,
  • vision problems,
  • heart dysfunction,
  • other.

Treatment of secondary glaucoma

In the treatment of this eye disease, different methods are used, from the treatment with pharmaceuticals to surgical and laser surgery, to stop the development of the disease and prevent further damage to the optic nerve and thus prevent blindness. Each procedure must, however, take into account the medical condition that contributed to the emergence of secondary glaucoma.
