Abstract:AIM: To investigate the utility of optomap panoramic 200Tx in screening fundus disease among the patients after cataract surgery.
METHODS: From November 18th to December 31st, 2013 all 146 post-cataract surgery patients were recruited. All non-mydriatic fundus images were taken with the optomap panoramic 200Tx and were diagnosed by one masked retinal specialist. Non-mydriatic direct ophthalmoscope exam and mydriatic slit-lamp lens exam were also done by other two masked specialists. Comparisons of the three methods were made.
RESULTS: Among 146 patients(161 eyes), 40 eyes(24.8%)of retinal lesions was detected by non-mydriatic direct ophthalmoscope exam, 59(36.7%)by non-mydriatic optomap 200Tx exam, and 61(37.9%)by slit-lamp lens exam. Nine eyes(5.6%)needed medical intervention immediately. Results of optomap 200Tx exams and slit-lamp lens exams were similar without statistically significant difference(P>0.05), better than direct ophthalmoscope exam(P<0.05)with statistically significant difference.
CONCLUSION:Opacification of the refractive medium makes thorough fundus examination impossible. So post-operative fundus examination is highly necessary and should be a routine. Optomap panoramic 200Tx, which shows no statistically difference from mydriatc slit-lamp lens exam, is a convenient and feasible method in discovering fundus pathological changes.
