This study surveys the current use of investigations for the management of glaucoma in hospital practice by UK ophthalmologists.
1047 questionnaires were posted to all active UK consultant ophthalmologists. They were asked to indicate whether university (UH) or general (GH) hospital, glaucoma specialist, and availability and use of automated perimetry, disc photography, HRT, GDx, OCT and pachymetry.
476 completed questionnaires were received; 285 (59.9%) GH, 186 (39.1%) UH, 146 (30.7%) specialists. There was good availability of automated perimetry (472, 99.2%), disc photography (423, 88.9%), and pachymetry (379, 79.6%), but suboptimal availability of OCT (214, 45.0%), HRT (208, 43.7%) and GDx (60, 12.6%). Availability of each test was better amongst UH consultants (p<0.0001), and glaucoma specialists.The majority of consultants used SAP (353, 74.2%) and SITA-fast (287, 60.3%) for glaucoma suspects and monitoring glaucoma (288, 60.5% and 198, 41.6% respectively). A significant number used Estermann (158, 33.2%) and Goldmann fields (91, 19.1%) for glaucoma suspects. There was no difference in choice of visual field between UH and GH, or specialist and non-specialist.HRT was used where available, by 176 (84.6%) and was the preferred investigation for disc asymmetry, early glaucoma, progression, ocular hypertension, normal tension glaucoma and unreliable visual fields, p<0.0001. Pachymetry was used by 337 (88.9%) consultants, more so amongst specialists.
There is variation in the use of investigations for the diagnosis and management of glaucoma reflecting the range of techniques available. SAP, SITA-fast and pachymetry are the most commonly used investigations followed by HRT.
