BACKGROUND: Anterior lens opacities (ALO) are found in 3-14% of pediatric
patients with cataracts. No clear guidelines exist in the management and
treatment of these cataracts. OBJECTIVE: To evaluate pediatric patients with
anterior lens opacities and assess rate of amblyopia and need for surgery over
time. METHODS: A retrospective chart review was performed on patients with
unilateral and bilateral anterior lens opacities (ALOs) seen between January 2008
and December 2014. Size, location, and type of ALO were noted. Refractive error,
necessity for treatment of amblyopia, and interventions were recorded. RESULTS: A
total of 31 patients were included in the study. 17 patients had unilateral ALOs
and 14 had bilateral ALOs. The majority of the cataracts (90.3%) were centrally
located. The most common type of cataract was the polar type of cataract and the
vast majority (48.4%) was < 1mm in size. 38.7% of patients had concurrent ocular
conditions and 9.7% had systemic associations. 28.6% of patients with bilateral
cataracts and 35.3% of the patients with unilateral cataracts were treated for
amblyopia. Three patients required cataract surgery. CONCLUSION: About half of
anterior lens opacities are less than 1mm in size and the majority are of the
polar type. Risk of amblyopia in these patients is higher than in the general
population. Anisometropia is the most common cause of amblyopia. Ocular
associations are seen at a relatively high frequency and systemic associations
can occur but are uncommon. The need for surgical intervention is infrequent;
however, growth of ALOs and associated cortical changes may be risk factors for
surgery.
