Goggles are often used in competition as well as recreational swimming and offer great benefits such as increased visibility under the water’s surface and protection of the eyes from chemical irritation and bacteria. However, goggle wear has also been associated with periorbital and ocular injuries and diseases such as optic nerve avulsion, supraorbital neuralgia, and contact dermatitis. Wakely was the first to report the potential risk of glaucoma associated with the wearing of swimming goggles in 2004. He noted that goggles create excessive negative pressure that may lead to prolonged drainage bubbles in patients who have undergone trabeculectomy. In 2008, Morgan et al. found that wearing swimming goggles with a small surface area increased intraocular pressure by an average of 4.5 mm Hg. Another study confirmed the correlation between wearing swimming goggles and increased intraocular pressure and speculated that certain types of goggles may reduce the blood supply to the intracranial optic nerve, making them an important factor in the development of glaucoma. Another study confirmed a correlation between wearing goggles and increased intraocular pressure and speculated that certain types of goggles may reduce blood supply to the intracranial optic nerve, making them a risk factor for the development and/or exacerbation of glaucoma. The study researchers, Maria Franchian et al. of the University of Western Australia, recruited members of local swimming clubs and subjects who participated in other sports (besides swimming) wearing goggles to investigate whether wearing swimming goggles increased the prevalence of glaucoma. The study surveyed 213 members of local swimming clubs and 118 non-swimmers for demographics, disease history, and goggle wear questionnaires; subjects were evaluated for glaucoma based on a detailed ophthalmic examination including intraocular pressure, visual field, and retinal nerve fiber layer thickness. The results showed that no glaucoma was found in the swimming group based on the results of intraocular pressure and visual field. Intraocular pressure was 15.1 ± 3.6 mmHg and 15.3 ± 3.9 mmHg in the swimming and non-swimming groups, respectively, and was not statistically different (P = 0.652). Similarly, there was no statistical difference in retinal nerve fiber layer thickness between the swimming and non-swimming groups: the mean right eye bulb thickness (Global Thickness, GT) was 94.0 μm (interquartile range IQR: 88.0, 100.3) in the swimming group and 93.0 μm (interquartile range IQR: 89.0, 101.0) in the non-swimming group (P = 0.976). The mean left ocular thickness (GT) in both groups was 93.7 μm (interquartile IQR: 88.0, 101.0). The results of this large sample study point to the fact that regular wearing of swimming goggles does not increase the risk of glaucoma in adults, and it was determined that swimmers without a prior history of glaucoma do not develop glaucoma as a result of wearing swimming goggles.
