Answer: For the exploration of the globe, report an unlisted-procedure code, 67299 (Unlisted procedure, posterior segment). If the ophthalmologist also performed an orbitotomy (exploration of the orbit), report procedure code 67400 (Orbitotomy without bone flap [frontal or transconjunctival approach]; for exploration, with or without biopsy).
Hidden trap: Stay away from +67340 (Strabismus surgery involving exploration and/or repair of detached extraocular muscle[s] [list separately in addition to code for primary procedure]). Even though it seems to describe some of the surgery the ophthalmologist performed, 67340 is an add-on code. CPT rules specify that you must report 67340 in conjunction with strabismus surgery codes 67311-67334, and you wouldn't report those codes in this scenario.
