If hypermetropia is not corrected for a long time the following complications may occur:
1. Recurrent styes, blepharitis or chalazia may occur, probably due to infection introduced by repeated rubbing of the eyes, which is often done to get relief from fatigue and tiredness.
2. Accommodative convergent squint may develop in children (usually by the age of 2-3 years) due to excessive use of accommodation.
3. Amblyopia may develop in some cases. It may be anisometropic (in unilateral hypermetropia), strabismic (in children developing accommodative squint) or ametropic (seen in children with
uncorrected bilateral high hypermetropia).
4. Predisposition to develop primary narrow angle glaucoma. The eye in hypermetropes is small with a comparatively shallow anterior chamber. Due to regular increase in the size of the lens with increasing age, these eyes become prone to an attack of narrow angle glaucoma. This point should be kept in mind while instilling mydriatics in elderly hypermetropes.
