“…Systemic associations with ALOs, while reported, are uncommon. None of the systemic associations in our study were life-threatening, although the association of ALO with retinoblastoma has been described in 2 separate studies [1, 4, 9]. …”

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.

“…Dot-like anterior polar cataracts may be unilateral or bilateral (usually symmetrical) and consist of tiny white dots of variable size 12 on the anterior lens surface in an axial location; they are usually not visually significant, 12 probably representing an abnormality of lens vesicle detachment from the surface ectoderm. Ophthalmic associations include aniridia and retinoblastoma 16 and cornea guttata, as well as corneal astigmatism. 17 Systemic associations include cerebral malformations.…”

Catarata polar anterior piramidal deslocada para a câmara anterior causando edema de córnea -Relato de caso Cataratas polares anteriores piramidais são opacidades cônicas que se projetam para a câmara anterior a partir da cápsula anterior do cristalino. Na grande maioria dos pacientes a opacidade permanece aderida e estável durante toda a vida. O objetivo deste trabalho é documentar uma manifestação incomum desse tipo de catarata: a deiscência espontânea das pirâmi-des para a câmara anterior causando descompensação endotelial e edema corneal bilateral. Relatamos o caso de uma paciente feminina, de 66 anos, branca, que apresentava edema corneal localizado inferiormente no olho direito associado à lesão nodular branco-esclerótica compatível com a pirâmide anterior da catarata polar. O olho esquerdo apresentava edema corneal difuso intenso e presença de uma catarata polar anterior com a região piramidal deslocada para a câmara anterior. Sabe-se que a pirâmide anterior pode permanecer inabsorvida na câmara anterior por longo perío-do, pois é composta de tecido colágeno denso. Isto causa perda endotelial progressiva e edema corneal e deve ser considerada indicação de remoção cirúrgica da catarata polar anterior e de seu fragmento. Ressalta-se, também, a importância do bom senso no julgamento das cataratas polares anteriores, considerando-se tamanho da opacidade, simetria das opacidades e componente cortical associado, na tentativa de se evitar ambliopia. INTRODUÇÃOCataratas piramidais anteriores são opacidades cônicas que se projetam para a câmara anterior a partir da cápsula anterior do cristalino. Têm origem similar às cataratas polares anteriores (CPA) comuns, mas são maiores em diâmetro e altura. São congênitas, na maioria das vezes bilaterais e assimétricas, ocorrendo geralmente em pacientes saudáveis, sem outras anormalidades sistêmicas ou oculares (1)(2) . Atualmente, sabe-se que as cataratas polares anteriores estão associadas à alta morbidade visual, principalmente pela freqüente associação com estrabismo, anisometropia e ambliopia (2) .O objetivo deste trabalho é documentar uma manifestação incomum das CPA piramidais: a deiscência espontânea das pirâmides anteriores para a câmara anterior causando descompensação endotelial e edema corneal bilateral.
