Insights
Congenital eye conditions in children are often linked to consanguinity and maternal factors. Early awareness and genetic counseling can significantly reduce childhood blindness.
Area of Science:
- Ophthalmology
- Pediatrics
- Genetics
Background:
- Congenital ocular morbidity in children presents a significant public health challenge.
- Understanding the etiological factors is crucial for effective prevention and management strategies.
Purpose of the Study:
- To analyze the congenital causes of eye diseases in children aged 0-12 years.
- To identify risk factors associated with these conditions, including consanguinity and maternal characteristics.
Main Methods:
- A prospective study was conducted over two years (Jan 2021-Dec 2023) at RL Jalappa Hospital and Research Center.
- Data collected included patient demographics, family history, parental consanguinity details, and specific ocular diagnoses from 56 pediatric patients.
Main Results:
- Nasolacrimal duct anomalies (32%) and congenital esotropia (14%) were the most prevalent conditions.
- A high rate of consanguineous marriages (61%) was observed among parents, with a significant proportion involving second or third-degree relatives.
- Bilateral ocular involvement was noted in 55% of the cases.
Conclusions:
- Consanguinity and other genetic factors play a substantial role in congenital eye morbidity in children.
- Maternal age and prenatal factors also contribute to the risk.
- Routine healthcare education, awareness programs, and genetic counseling are essential to mitigate these risks and prevent childhood blindness.
Abstract:
An analysis of the congenital etiologies of ocular morbidity in children of age 0-12 years is of interest. Hence, this study was conducted over a period of 2 years from Jan 2021- Dec 2023 at RL Jalappa Hospital and Research center that is attached to Sri Devaraj Urs Medical College, Tamaka, Kolar, Karnataka, India. Out of 56 patients, 57% were male and 43% were female children. 31 (55%) of mothers belonged to age group between 20-30 years and 24 (43%) between 31-40 years and 1(2%) between 41-50 years. Out of 56 patients, 14 (25%) of them had positive family history. 34 (61%) of them had consanguious marriage. 14 parents (41%) out of 34 are married to second degree consanguinity (brother/sister/grandparent/grandchild) and 20 (59%) belonged to third degree consanguinity (aunt/uncle/niece/nephew/great-grandparent/great-grandchild). Bilateral involvement was seen in 31 (55%). Nasolacrimal duct anomalies were found to be the most common (32%) followed by congenital esotropia (14%). Education, awareness, counseling about risks of consanguinity and other risk factors such as maternal age, infections, medications during pregnancy, vaccination must be a routine practice in healthcare set up. This can significantly reduce morbidity and prevent blindness.
