PurposeTo study features of Indocyanine green angiography (ICGA) in patients with presumed intraocular tuberculosis.MethodsRetrospective study of 48 consecutive patients (77 eyes) who underwent ICGA. The following signs were analysed: choroidal perfusion inhomogeneity, early hyperfluorescent stromal vessels, round or oval hypofluorescent dark dots (HDDs), hypofluorescent geographic lesions (HGLs), fuzzy or lost pattern of large stromal choroidal vessels, disc hyperfluorescence and diffuse late choroidal hyperfluorescence.ResultsAmong 44 eyes of 29 patients with no clinical evidence of choroidal involvement, only 7 eyes of 6 patients had no ICGA evidence of choroidal involvement. On the other hand, ICGA findings suggesting choroidal involvement were noted in 37 (84.1%) eyes of 23 patients in the form of HDDs in all 37 (100%) eyes, HGLs in 7 (18.9%) eyes, disc hyperfluorescence in 20 (45.5%) eyes, fuzzy stromal vessels in 17 (38.6%) eyes, early hyperfluorescent stromal vessels in 13 (29.5%) eyes, late pinpoint hyperfluorescence in 11 (25%) eyes and late diffuse choroidal hyperfluorescence in 7 (15.9%) eyes. Among 33 eyes of 19 patients with clinically evident choroidal involvement, the following findings were identified; HDDs in 12 (36.4%) eyes, HGLs in 10 (30.3%) eyes, both HDDs and HGLs in 9 (27.3%) eyes, disc hyperfluorescence in 11 (33.3%) eyes, early hyperfluorescent stromal vessels in 7 (21.2%) eyes, fuzzy stromal vessels in 6 (18.2%) eyes and late diffuse choroidal hyperfluorescence was present in 2 (6.1%) eyes.ConclusionsICGA is necessary in identifying and diagnosing subclinical tuberculous choroidal involvement. The most prevalent ICGA finding was persistent HDDs.Subject terms: Tomography, Outcomes research |
