PROSPECTIVE STUDY OF ROLE OF CONTRAST SENSITIVITY AND COLOUR VISION IN CENTRAL SEROUS CHORIORETINOPATHY.
Journal Title: International Journal of Advanced Research (IJAR) - Year 2018, Vol 6, Issue 2
Abstract
Aim: To evaluate Contrast sensitivity and Colour vision during and after resolution of sub retinal fluid in Acute central serous retinopathy and their relation with the Visual acuity(VA) and Central macular thickness(CMT). Methodology: In this prospective observational study from Jan 2017 ? sep 2017, 35 patients within the age group of 20-50 years were included. Patients are then divided into 2 groups depending on time taken for absorption of Sub retinal fluid (SRF) .Early resolution group(within 3 months)and delayed resolution group(>3 months) ,and all the patients included in the study were followed for 6 months. Results: In the early resolution group(68.6%) Best corrected visual acuity( BCVA) 6/6 attained by 2 months, Contrast sensitivity becomes normal by 4.5 months, Colour vision attained normal range by 4 months . In the Delayed resolution group (31.43%), BCVA attained by 6months, even in cases with residual SRF. 63.6% cases showed moderate loss of contrast sensitivity(CS) and tritanopia even after complete resolution of SRF and with normal visual acuity. Persistent SRF cases (3 cases) showed severe colour vision loss and moderate CS loss. Conclusion: In the early resolution group the recovery of fine vision took about 1 month after resolution of SRF. In the delayed resolution group, the visual acuity showed low rate of improvement, attaining normal range by the end of 4th month and 63.6% patients showed moderate contrast sensitivity loss even after resolution of SRF and with normal visual acuity. 63.63% of cases showed colour vision defect by the end of 6th month even after resolution of SRF, and had disturbed vision due to loss of colour and contrast sensitivity, necessitating the need for measures of early intervention like Laser or medical therapy to hasten early resolution of CSC, so that fine vision can be preserved in young working age group especially certain professions like drivers and pilots.
