Optical coherence tomography in the evaluation of retinal change aociated with upiciou choroidal melanocytic tumor

Purpoe ubretinal fluid (RF) i a trong rik factor for growth of choroidal melanocytic tumor. However, ubtle RF can be difficult to ae clinically and to ditinguih from chronic retinal change overlying a dormant leion. Thi tudy invetigate optical coherence tomography (OCT) in evaluating RF in upiciou choroidal melanocytic tumor. Deign Interventional cae erie. Method Review of 33 patient with untreated choroidal melanocytic tumor who underwent OCT for upicion of ubtle RF. Fluorecein angiography wa performed in 26 of the patient. The main outcome wa tumor growth. Reult No retinal eparation wa found in 12 tumor, of which 1 (8%) grew on follow-up and 3 (25%) were treated. Chronic retinal change (localized retinal eparation with retinal atrophy or intraretinal cyt) were found in nine tumor: one (11%) grew on follow-up and none were treated. Active RF (localized retinal eparation with normal retinal appearance) wa found in 12 tumor: 6 (50%) grew on follow-up, and 7 (58%) were treated. The active OCT pattern wa aociated with fluorecein angiography hotpot (P = .041), documented tumor growth (P = .033), and tumor treatment (P = .014), and inverely aociated with druen (P = .024), atrophic retinal pigment epithelium change urrounding the tumor (P = .048), and intraretinal cyt by OCT (P = .002). Concluion Optical coherence tomography i ueful in ditinguihing active ubretinal fluid from chronic retinal change overlying a choroidal melanocytic tumor. Optical coherence tomography finding may have predictive value in identifying tumor that are likely to grow and require treatment.
