Titel	Long-term evolution of age-related distance esotropia
Abstract Nr.	1048

Doel	To evaluate the evolution of horizontal deviation and fusional amplitudes both at distance and at near in patients with age-related distance esotropia.
Methodes	Thirty-one elderly patients, aged between 64 and 86, presenting permanent or intermittent distance esotropia with a follow-up of at least 60 months (60 months to 161 months; average 80.2 months) were included in this study. Horizontal deviation, fusional convergence and divergence amplitude were measured both at distance and near. First and last measurements were compared.
Resultaten	Distance esodeviation ranged between 2 and 12 prism dioptres (PD) esotropia (ET) at the initial examination, and ranged between 2 and 25 PD ET at the final examination. Near deviation varied from 10 PD exophoria (X’) to 8 PD esophoria (E’) at the initial examination, and ranged between 4 PD X’ and 14 PD ET’ at the final examination. Fusional divergence amplitude at distance ranged between 0 and 10 PD both at the initial examination and at the final examination. At near, fusional divergence amplitude ranged between 4 and 18 PD at the initial examination, and ranged between 2 and 16 PD at the final examination. Fusional convergence amplitude at distance ranged between 4 to 22 PD at the initial examination, and ranged between 5 and 22 PD at the final examination. At near, fusional convergence amplitude ranged between 10 and 44 PD at the initial examination, and ranged between 8 and 42 PD at the final examination.
Conclusie	This study indicates that patients with age-related distance esotropia experience a slight increase in distance esodeviation both at distance (p < 0.001) and at near (p = 0.004), while no significant change in fusional amplitudes were observed over time (p ≥ 0.05).
