The article discusses the occurrence of diurnal and long-term intraocular pressure (IOP) fluctuations. Diurnal fluctuations in IOP occur in both healthy eyes and in the eyes of glaucomatous patients. Multiple studies to assess the IOP variations that happened over a full 24 hours are conducted at a sleep laboratory at the University of California in San Diego. It is found that IOP tends to be higher in the glaucomatous subjects who tend to have higher pressures during the nocturnal period.

The article features the glaucoma risk calculator, an instrument that estimates an individual patient's global risk for developing glaucoma, created by Felipe A. Medeiros and Robert N. Weinreb in San Diego, California. The tool is also designed to help practitioners identify persons who are likely to benefit from intraocular pressure lowering treatment.

The article presents a research to provide risk assessment for ocular hypertension at the Hamilton Glaucoma Center at the University of California in San Diego, California. The purpose of the study is to identify patients at moderate to high risk for conversion from ocular hypertension to glaucoma and help decide if the therapy is warranted. The Ocular Hypertension Treatment Study found that 9.5 percent of the ocular hypertensives who were left untreated progressed to glaucoma.
