Annex B. Xerophthalmia field survey forms

The following field survey forms are modifications of those found useful in the Indonesian Nutritional Blindness Prevention Project. They are examples of the types of information and format that can be employed, but should be modified depending upon local conditions, interests, and abilities. They have been kept simple and include only those factors felt to be most relevant to an understanding of the xerophthalmia problem.

 

Clinical Examination Form

This form is primarily intended for children under the age of six. If older individuals are to be examined or other major causes of blindness exist or are of interest (e.g., trachoma, onchocerciasis, etc.), it should be modified and expanded. A full-scale paediatric or nutritional survey would include many additional measurements.

The ocular examination must be carried out by someone familiar with the clinical manifestations of xerophthalmia, preferably an ophthalmologist. The location and size of all corneal abnormalities should be carefully indicated in the circles provided.

The summation coding format maintains discrete information while economizing on punch-card columns. Simply circle the score for each abnormality present. add the scores for each section, and transfer the totals to the appropriate columns alongside. Where none of the abnormalities listed is present, the total is "O"; this should be entered in the appropriate space. At the completion of the examination, there should be a digit in each of the numbered spaces, even if it is "O".

 

Clinic Based Case Reporting Form

A simple line listing as shown here, is sufficiently detailed to monitor the number, types, and origin of cases presenting at treatment facilities. It has been kept short and simple to facilitate its use by overworked clinic personnel.
