The approach of the book is to take selected differential diagnosis from Ocular Differential Diagnosis (ODDX) and combine with Ocular Syndromes and Systemic Disease.

This provides evidence-based differential diagnosis with listings with each item.

Ptosis, for example, has large categories of congenial and adult-onset ptosis.

These disease entities are divided into age of onset and then a descriptive list of possible causes are listed under each category.

Although drug dosages and methods of administration have been scrutinized, it is important that each physician exercise his or her own judgment in the choice or use of a drug.

The physician is advised to check the product information included in the drug’s package insert before drug administration.

New data and individual clinical situations can change the drug regimen.
