Dr. Allen is a full-time, board-certified, oculoplastic surgeon in Austin and Houston, Texas.  His primary employer is Texas Oculoplastics Consultants in Austin, Texas.  He sees pediatric patients at Texas Children's Hospital in Houston, cancer patients at MD Anderson Cancer Center in Houston, and general oculoplastic patients at TOC.  His procedures range from routine outpatient surgeries to extremely complex, multi-disciplinary inpatient cases. 


He is deeply committed to medical education and exceptional patient care.  To this end, he created Oculoplastic Surgery Videos, an archive of over 300 narrated videos that are available to all, free of charge.  Currently over 10,000 people follow OSV online on Facebook, and over 15,000 follow him on YouTube.  On these sites, Dr. Allen introduces a new topic weekly and answers questions from physicians all over the world.  It is a singular project without equal in ophthalmology today.  The "classic" (pre-2015) videos are hosted by The University of Iowa Hospitals and Clinics, where Dr. Allen both trained and worked on faculty prior to returning to Texas.  To access the videos, please click here.  His YouTube page includes these classic videos as well as his new videos.  To access his YouTube page, please click here.

Dr. Allen is happily married to his wife of 30 years, Missy.  She is an enthusiastic advocate for his domestic and international medical education initiatives, working as his partner in his Oculoplastic Surgery Videos programs.  Their life together has been one of purpose, each working towards a more democratic and barrier-free access to excellent education and health care.  They have two children, Augustus and Astrid, and currently divide their time between Austin and Houston.  In his increasingly rare time away from ophthalmology, he enjoys long distance bicycling, running, and listening to music.

Manual of Oculoplastic Surgery, 5th ed.


This best-selling, step-by-step guide to oculoplastic surgery has been highly respected and widely used by ophthalmologists, oculofacial plastic fellows, residents, ENT-facial plastic surgeons, and general plastic surgeons. The revised and updated fifth edition of Manual of Oculoplastic Surgery is designed to guide the physician in exploring and completing a variety of ocular plastic procedures in a comprehensive and logical step-by-step sequence.


Basic Ophthalmology:  Essentials for Medical Students, 10th ed.


Basic Ophthalmology is an ideal complement to the medical student curriculum and is a key text for primary care residents and physicians who want to broaden their knowledge of eye disease diagnosis and treatment.  Clinicians will learn how to obtain an appropriate ocular history and perform a complete eye evaluation. From the history and findings, the clinician should be able to diagnose and manage or refer common ocular disorders.  This new edition includes content updates, 140+ figures and 17 video clips. The practical text summarizes important concepts, describes techniques step-by-step, and provides resources for additional information.
