**7. Conclusion**

Early diagnosis and treatment of fungal keratitis remains a challenge. A better understanding of pathogenesis can broadened the approach to management**.** Recent advances in techniques such as in vivo confocal microscopy and the evolution of PCR and MDS can useful in rapid and accurate diagnosis. Newer antifungal agents and newer methods of targeted drug delivery system can be helpful in treating refractory cases and improving outcome. New evolving technique like PACK-CXL and RB-PDT can be useful as adjuvant therapy.

New researches are continue to investigate the new aspects of pathogenesis, to device the novel drug delivery system to overcome the poor ocular penetration of antifungal drugs and enhance their efficacy and evaluate newer antifungal drugs. In recent years focus on modifying the immune response to the infection, thereby reducing the corneal melting and scarring which lead to poor vision, may have the greatest potential to improve visual outcomes.
