Characteristics and therapeutic effect evaluation of divergence paralysis / 眼科新进展

ABSTRACT

Objective To investigate the clinical features of divergence paralysis improve the diagnostic and therapeutic ability,and evaluate the effect of surgical and non-surgical treatment.Methods It was a retrospective case series study.11 cases with complete data,diagnosed and treated as divergence paralysis in Tianjin Eye Hospital from September 2014 to January 2016,were summarized.The observation items included general date,neurologica consultation,comprehensive eye examination,and the eye position and movement,deviation degree,binocular vision,AC / A,diplopia examination of pre-treatment and post-treatment.The patients were followed up from 3 months to 1.5 yeas,averaged 6.9 months.Results In our study,1 patient was MillerFisher syndrome,3 cases had a history of hypertension,and 1 case had the history of intaking sleeping pills for about 3 months.The rest of the patients denied the nervous system disease,cardiovascular disease and other medical history.All patients complained about uncrossed diplopia only at distance.All of the 11 patients had a sudden onset of their symptoms.Each patient was examined by same neurologist,meanwhile MRI or CT were performed.All the results showed normal.All patients had refractive error.The angle of esotropia for distance of 5 meters was from + 25 △ to + 55 △ and was from + 8 △ to + 40△ for near(33 cm)before treatment while changed into-4△ ～ + 12△ for distance (5m) and to-8△ ～ +8△ for near (33 cm) after treatment.The ratio of AC / A ranged from 1.3 to 4.0,with an average of 2.6.Conclusion The clinical characteristics of divergence paralysis are a greater angle of esotropia and ipsilateral diplopia.Lateral rectns resection and non-surgical treatment have better effects on the improvement of diplopia and esotropia.
