Tranexamic acid-associated ligneous conjunctivitis with gingival and peritoneal lesions.

A considerable number of agents have been proposed as causing ligneous conjunctivitis. We report the first case to arise as a side effect of tranexamic acid (Cyclokapron), an anti-fibrinolytic drug used in the treatment of menorrhagia. In addition to the typical conjunctival changes our patient had lesions affecting the gingiva and the peritoneum the last causing considerable protein loss into the peritoneal cavity.

Preferential looking in the mentally handicapped.

We have assessed the feasibility of Preferential Looking (PL), using Teller Acuity Cards, for the estimation of binocular and monocular visual acuities in a group of mentally handicapped adults. Our results show the comparison between grating and recognition acuities, inter-observer variation, success rate, time taken and the sensitivity of this method in identifying monocular visual deficit in this group of subjects. The reasons for success or failure with PL methods in relation to criteria for mental handicap are discussed.

Preferential looking in clinical practice: a year's experience.

Preferential Looking (PL) is now a well established laboratory method of measuring visual acuity in preverbal children. We have evaluated the feasibility of its routine use in clinical practice. We present our methods and results obtained in 80 normal children and 36 children with visual disorder and discuss the problems encountered in applying this test.

Aluminium phosphide poisoning: a prospective study of 16 cases in one year.

Sixteen patients suffering from aluminium phosphide poisoning were treated during the year from January 1985 to December 1985. These accounted for approximately half the total number of cases of acute poisoning. Profuse vomiting, pain in the upper abdomen and shock were the most common presenting features. Six patients succumbed to their illness. Analysis of various prognostic factors revealed that ingestion of 'unexposed' tablets of aluminium phosphide taken from a freshly opened bottle was associated with a greater risk of fatal outcome. Aluminium phosphide poisoning has become an important matter of public health in parts of India.

Binocular fixation pattern and visual acuity in children with strabismic amblyopia.

BACKGROUND: A prospective study was undertaken to compare the binocular fixation pattern and presence of amblyopia in strabismic children. METHODS: Fifty-three children with manifest strabismus and the ability to cooperate with an optotype acuity test were examined. The binocular fixation pattern and logMAR visual acuity were recorded by separate, masked observers under standardized conditions. The binocular fixation pattern was divided into four grades from alternation to uniocular fixation. RESULTS: Patients who freely alternated did not have amblyopia, while those who maintained or preferred fixation with a given eye tended to have amblyopia in the nonpreferred eye. CONCLUSION: The binocular fixation pattern can be rapidly assessed with minimal equipment and training. These findings confirm the usefulness of a graded assessment of the binocular fixation pattern in the detection of amblyopia.

Linear assessment of anteroposterior jaw relationship.

Three Linear methods of establishing the sagittal relationship of the maxillary and mandibular apical bases were compared using Lateral skull radiographs of thirty individuals having Class II div. 1 malocclusion. Statistical evaluation was done for wit appraisal, AD' distance, and Wylie analysis. The A-D' distance is recommended for use during sagittal apical base relationship.
