Twenty-four hour pattern of intraocular pressure and ocular perfusion pressure in night shift workers
Kara N; Yilmaz TSeminars in Ophthalmology 2015; 30: 188-192
PURPOSE: To investigate the intraocular pressure (IOP) and ocular perfusion pressure (OPP) in night shift workers. METHODS: Seventy-one healthy individuals who work the night shift were evaluated. IOP and OPP were measured in the sitting position in each participant. Measurements were obtained at rest time (09:00, 12:00, 16:00) and night-shift time (20:00, 24:00, 04:00, 08:00). RESULTS: The mean age of the 33 females and 38 males was 35.6 ± 7.5 years (range 20-53 years). Mean IOP values were different between the measurements at 9:00 and 12:00 (p = 0.00), at 9:00 and 16:00 (p = 0.00), at 12:00 and 16:00 (p = 0.00), at 16:00 and 24:00 (p = 0.02), at 24:00 and 04:00 (p = 0.02), and at 24:00 and 08:00 (p = 0.00). Mean OPP values were significantly different only between the measurements at 9:00 and 20:00 (p = 0.01). CONCLUSION: This study revealed that IOP and OPP in night shift workers show 24-hour variations.
