Using a special camera to examine eye muscles after surgery to fix crossed eyes - A study

Not yet recruiting

• Conditions: Disorders of ocular muscles, binocular movement, accommodation and refraction,

• Registration Number: CTRI/2023/04/051497
• Lead Sponsor: Dr Hari Bhadari Anand

Brief Summary

**Primary Objectives:**

·       To analyse the percentage of EOM we are able to locate at the new insertion point post squint-correction, via AS-OCT

.

**Secondary Objectives:**

To study which paediatric age group will be co-operative for this modality of scanning.

·       To define field-limits for detection of EOM.

·       To explore the minimum post-operative period when the muscle can be visualised clearly.

·       To study changes in insertion-site of the operated EOM post-operatively.

·       To correlate between axial length and the field of limits of detection.

**Expected Outcome****:**  We expect to find what muscles and upto which extent of resection can be visualised under AS-OCT post-operatively, to find what age group of children will be co-operative to testing via AS-OCT & to define the post-op timeframe from which AS-OCT might be a viable investigation to clearly distinguish the insertion of the EOM.
