Confrontation visual fields to careful finger counting were constricted however, confrontation testing appeared to be unreliable as patient’s cooperation was poor during the entire exam. Extraocular motilities were full OU. Both pupils were equally round, however poorly responsive to light with no RAPD. Intraocular pressures measured 12mmHg OU.
Examination revealed bilateral Ocular adnexa and Anterior segments to within normal limits. Anterior chambers were quiet and deep OU. Dilated fundus examination revealed both vitreous clear OU.
