Message from the Editor-in-Chief

Dear Colleagues,

As ophthalmologists, one of the most exciting facets of our profession is our role as problem-solvers. Some of our patients have typical complaints and clear signs pointing to their pathologies, while others have complex, multifactorial problems, often connected to underlying systemic conditions that require all of our clinical skills and knowledge to accurately diagnose and treat. 

In this issue of eye Insights, we take a close look at two common oculoplastics disorders seen in ophthalmology practice: primary acquired nasolacrimal duct obstruction (PANDO) and orbital inflammatory syndrome (OIS). Inside, you’ll find key information about how PANDO and OIS are diagnosed and treated, guidance on when to refer a patient, and further reading.

Keep in mind that ophthalmic plastic surgery is a unique specialty that relies on a surgeon’s technical ability and artistic skill. For a list of doctors that specialize in this type of surgery, please visit the website for the American Society of Ophthalmic Plastic & Reconstructive Surgery. 

We hope you find this issue of eye Insights useful in your practice. Back issues are available online at If you have questions or comments, please email us at
