But their availability has not eliminated the need of classical principles of diagnostics and management of ocular pathology and even underscored the role of physician in establishing the correct diagnosis. In many cases the latter can save precious time and allows prescribing the correct and timely treatment.

This book is new, comprehensive and clinically relevant with in-depth focus on anterior segment diseases. Among the latter the authors concentrated on the vital areas of the eye surface abnormalities including pathology of tear film, diseases of conjunctiva, eyelids, cornea and sclera, developmental abnormalities and tumors.

The majority of the book chapters follow the template including: introduction; clinical signs and symptoms; investigations; differential diagnosis; general principles of treatment and prognosis.

This advanced book has a primary goal on presenting the updated guidelines that I consider extremely valuable for the ophthalmologists.

In realization of this ambitious project the works of the editors Dr A Garg and Dr E Rosen and Section Authors have been essential in achieving the goal for it, namely “establishing the instant and correct clinical diagnosis”.

After detail research and need of ophthalmologists we have developed a series of 10 Volume Ready Reference Books termed as Instant Clinical Diagnosis in Ophthalmology. This series covers Oculoplastic and Reconstructive Surgery, Retina, Lens, Glaucoma, Refractive Surgery, Pediatric Ophthalmology, Strabismus, Anterior Segment Diseases, Cornea and Neuro-ophthalmology. Present series has been designed to provide up-to-date information of concerned disease in a comprehensive and a lucid manner along with high quality clinical photographs in an easy to read format. International Masters of concerned subject have contributed chapters in this series covering pathophysiology, clinical signs and symptoms, investigations, differential diagnosis, treatment and prognosis in a simplified manner.

Present volume deals with all types of anterior segment diseases specially congenital and developmental anomalies, tear film disorders specially dry eye, various conjunctival and corneal diseases (infectious, inflammatory, neoplastic, degenerative and trauma), sclera and episclera, iris and ciliary body and finally keratoplasty in a comprehensive manner. Anterior segment diseases are clinically very significant specially corneal diseases which are one of the major causes of irreversible blindness worldwide. Proper and intime diagnosis of corneal diseases is very crucial. This volume shall help the ophthalmologists achieve this goal.

We are highly thankful to our publisher M/s Jaypee Brothers Medical Publishers Pvt. Ltd. specially Sh. Jitendar P Vij (CEO), Mr. Tarun Duneja (Director, Publishing) and all staff members for their dedication and hard efforts put in the preparation of High Quality Series of Instant Clinical Books.
