Q12.3

Clinical Causes: Genetic mutations that interfere with normal lens development Presence of inherited syndromes involving ocular anomalies Environmental factors affecting fetal development, such as intrauterine infections Maternal exposure to certain medications or toxins during pregnancy

Key Symptoms: Severe visual impairment or blindness in the affected eye A small or abnormally shaped eyeball (microphthalmia or nanophthalmia) Absence of the lens visible upon eye examination Potential associated eye abnormalities like coloboma or other congenital malformations Lack of lens reflex in the affected eye

Diagnosis Path: Detailed eye examination to assess eye structure and presence or absence of the lens Ultrasound imaging to evaluate eye development and identify structural anomalies Genetic testing if a syndromic association is suspected Assessment for other ocular or systemic abnormalities

Treatment Protocols: Corrective lenses or glasses may be recommended if residual vision can be improved Contact lenses or implant options might be considered in certain cases Surgical interventions are generally limited; however, ocular surgeries might be performed to correct related anomalies Optical aids and vision therapy can help improve remaining vision Regular follow-up with ophthalmic specialists to monitor eye development and manage complications
