Aims: To assess the prognosis in eyes having Mature cataract by Conventional Macular Function tests and B- Scan Ultrasonography, to analyses the utility of both in Mature cataract and to compare the post-operative status in relation to results of both. Design, Methods and Material: A hospital-based Cross-sectional study was conducted on 177 patients with mature cataract from July 2018 to August 2019 in a Tertiary care hospital in South Gujarat. The Conventional macular function tests likePupillary light reaction, Projection of light and Perception of rays, Color vision test, Maddox rod tests, Two-point discrimination test and B Scan were performed. Statistical analysis used: Data collected and put in excel sheet and were analyzed using Statistical Package for the Social Sciences (SPSS) 16.0 software. For the descriptive analysis, the mean, standard deviation, and percentage were used. The chi-square test applied for the comparative analysis. A p value < 0.05 was considered be statistically significant. Results: Age range was 25 to 90 years with mean age of 58 years. 75 patients were male and 102 females. Pupillary light response was normal in majority of cases. Color vision was normal in all the patients. Binocular Maddox rod test revealed red spot in 63.3%, polyopia in 28.2%, and white spot in 8.5% patients. Majority of the patients with abnormal B Scan had white spot response on Maddox rod test. In hyper mature cataract, majority of the patients were not able to discriminate or had short discrimination distance.Most of the patients with abnormal B scan findings were not able to discriminate. B Scan ultrasonography was normal in 61.2% patients. 34.4% patients had Vitreous detachment,vitreous haemorrhage seen in 1.7%, posterior staphyloma in 1.7%, 0.50% had retinal detachment and 0.50% had vitreous haemorrhage with Retinal detachment. Conclusion: Conventional macular function tests were altered when there was an evident posterior segment abnormality seen on B Scan. So, in setup where B Scan Ultrasonography is not available, the conventional macular function tests do help in cases of mature cataract.
