ABSTRACT
Ophthalmology information system is concerned with the function and care of the eye and with the disorders that affect it. An ophthalmologist is a physician who has graduated from medical school and completed at least three additional years of special training in the diagnosis and treatment of eye disorders. Ophthalmologists are qualified to perform medical eye examinations, prescribe corrective eyeglasses and contact lenses, treat diseases of the eye, and perform eye surgery. Some ophthalmologists specialize in treating particular parts of the eye, such as the cornea (the transparent cap at the front of the eye) or the retina (the light-sensitive membrane lining the back of the eye). Others specialize in working with specific patient populations. Ophthalmology information system is to document information concerning eye problems. This project is written to help hospitals especially Niger Medical optics Enugu in the areas they encounter problems in keeping their record and the solution given to tackle those problem. The research was carried out of many difficulties such as time factors, money and inability to get much information that could have been of help. But still with all those the researcher came up with something readable and valuable to any body that goes through it. This project is implemented with the help of visual basic programming language and Microsoft access. The Microsoft Access is used for the database creation.

CHAPTER ONE
1.0 INTRODUCTION
Ophthalmology information system is used to record the presence of many disorders, ranging from simple vision problems to infections such as conjunctivitis and trachoma. Eye exams commonly reveal other health problems as well, such as high blood pressure, diabetes mellitus, and brain tumors. During an eye exam, an ophthalmologist uses an ophthalmoscope or other special instrument to view the interior of the eye, particularly the retina. A simple eye chart is often used to help diagnose the most common vision disorders: nearsightedness, farsightedness, and astigmatism while Ophthalmology information system is used to document the observation. These disorders are caused by an abnormally shaped eye that prevents the cornea and lens from correctly focusing light on the retina, resulting in distorted vision. They are typically treated with glasses or contact lenses. Two forms of laser surgery are sometimes used to reshape the eye’s cornea in order to reduce or correct nearsightedness or farsightedness, thereby reducing or eliminating the need for corrective lenses. In photo refractive keratectomy (PRK), an ophthalmologist uses a laser beam; with laser in situ keratomileusis (LASIK), the ophthalmologist uses a laser beam and a tiny blade to reshape the cornea.
A Computerized ophthalmologist information system for hospital variously also called clinical information system (CIS) is a comprehensive, integrated information system designed to manage the administrative, financial and clinical aspects of a hospital. This encompasses paper-based information processing as well as data processing machines.
