Purpose: To assess the therapeutic significance of patching, in patients of intermittent exotropia in relation to control of deviation, absolute measurements and stereopsis.

Material and Methods: This prospective study was carried out in the Strabismus and Paediatric ophthalmology clinic of a tertiary care hospital. Seventeen patients underwent patching of the dominant eye or alternate occlusion in case of no ocular preference, for a duration of 6 hours / day. Objective Prism cover test measurements, stereopsis evaluation and three point control of deviation scoring were done before and after the 6 months duration. Paired samples t test and Stuart-Maxwell marginal homogeneity test were employed for analysis.

Results: The mean near and distance deviation was 20.35 +/- 4.663 S.D and 21.18+/- 6.885 S.D improving to 13.82 +/- 5.065 S.D and 19.49+/- 5.478 S.D respectively (p<0.001). Angle of strabismus showed a positive trend and decline for near as well as distance measurements with conversion of exotropia subtypes into pseudo divergence excess. Improvement in stereopsis was noted with fine stereopsis of 60 sec seen in 14 patients (82.35%) post patching as against 9 patients (52.94%) before starting the treatment.(p=0.03). Control grading showed a significant improvement with 11 patients (64.70%) attaining a score of 1, whereas before the start of patching the majority i.e 10 patients (58.82%) had a control score of 3.(p=0.004)

Conclusion: Patching induces improvement in degree of control, stereopsis and reduction in angle of deviation.

Alkylphosphocholines and Quaternary Ammonium Compounds against Acanthamoeba Keratitis

Acanthamoeba keratitis (AK) is a sight threatening infection caused by the free-living amoeba Acanthamoeba. This infection is largely associated with contact lens wear and the recent increase in AK incidences highlights the ineffectiveness of existing curative and preventative treatments. Current curative and protective treatments being active in part, only against the infective trophozoites and often inducing their conversion to the protective cysts is a major issue, particularly when the latter are the main cause of disease resurgences and relapses. These point to the need for the discovery of new drugs for curative and preventive treatments. Two structurally similar chemical classes, alkylphosphocholines (APCs) and quaternary ammonium compounds (QACs) that address these issues will be discussed in this review.
