Introduction: Solitary uveal lesions confer a diagnostic challenge to ophthalmologists. Uveitic lesions most abundantly appear amelanotic and commonly involve the choroid. Most amelanotic choroidal lesions are either neoplastic or inflammatory in origin. In our study, we aimed to describe six uveitic granuloma cases, which were referred to a tertiary ophthalmology center as intraocular tumors.
Methods: Retrospective chart review of 6 patients (7 eyes) who had uveitic granulomas and were referred to a tertiary ophthalmology center as having intraocular tumors.
Results: Mean age on presentation was 47 ± 12.5 years. One lesion was involving the ciliary body only, five lesions had pure choroidal involvement, and one had ciliochoroidal involvement. Mean visual acuity on presentation was 1.7 ± 0.75 (Snellen = 20/1,000) and ranged from 20/80 to light perception. Mean basal diameter of all lesions was 7.7 ± 1.8 mm. Three lesions had moderate echogenicity, two lesions were low to moderate echoic, and one lesion had moderate to high echogenicity on ultrasonography. Three lesions were associated with retinal detachments. Five eyes showed an early hypofluorescence with late hyperfluorescence. Leakage of fluorescein at borders was noticed in 3 lesions. Final diagnosis was presumed intraocular tuberculosis in 4 patients, probable ocular sarcoidosis in 1 patient, and idiopathic solitary uveitic granulomas in 1 patient. Upon treatment, the vision improved to 0.3 ± 0.27 (Snellen = 20/40) and ranged from 20/20 to 20/100 after 4.7 ± 2.9 years of follow-up.
Conclusions: Uveitic granulomas can demonstrate features of ocular tumors. Proper uveitis management leads to a favorable visual outcome and ocular preservation.
