Indian Journal of Ophthalmology. 1989 Jan-Mar; 37(1): 20-3http://imsear.searo.who.int/handle/123456789/70400The practice of pre-operative 'Test Patch' on any eye continues to be an important, conventional step at a number of eye infirmaries. The present study was carried out on eighty seven eyes to determine the relevance of Test Patch as a prelude to surgery. After a critical analysis of the result of investigation, it is concluded that the 'Test Patch' does not provide a statistically reliable information regarding potential bacterial infection since there is no correlation between pre-patching and post-patching clinical appearance, and bacterial isolates in a given case. Presence of polymorphs or organisms in the Grams stained conjunctival smears did not make any difference with regard to a positive or negative bacterial growth in a given eye. It is concluded that 'Test Patch' neither predicts nor helps in any way in a case waiting to undergo intra ocular surgery. The Test Patch, therefore, at best, can serve as an acclimatizing exercise that simulates bandaging in the post-operative period.engBacterial Infections --diagnosisBandagesHumansOphthalmologic Surgical ProceduresPostoperative ComplicationsJournal Article
