Glaucoma

Glaucoma is nowadays popularly reclassified as a retinal disease rather than an optic nerve disease that it used to be considered as. The ability to image the retinal nerve fibre layer and the ganglion cell layer and their combined accuracy in detecting the onset and progression of Glaucoma has revolutionised our understanding of the disease. This has led to treatments that offer neuro- and vascular-protection for maintenance of enduring healthy vision.

Investigations

  • Automated perimetry – visual field testing
  • Corneal Pachymetry
  • Retinal Nerve Fibre Layer analysis on OCT scan.

Treatments

An overwhelming majority of patients are managed very well by treatment with eye drops alone. Some of the other modalities are listed below.

  • Laser trabeculoplasty
  • Filtration surgery
  • Ciliary body ablation with cyclodiode laser.

These other treatments carry a much higher risk, do not cure the disease and therefore reserved for the minority of patients in whom eye drops alone may not be satisfactory. No matter what treatments that patients may have, the follow-up for Glaucoma is lifelong.
