| Abstract | Purpose To compare the clinical outcomes of Maximum Tolerated Medical Therapy (MTMT) in patients with penetrating keratoplasty (PKP) with those of Ahmed glaucoma valve (AGV) implantation. Methods The medical records were retrospectively reviewed in patients who had undergone PKP for bullous keratopathy and were treated with MTMT or AGV implantation for the management of glaucoma. A total of 18 bullous keratopathic patients were investigated between January 2010 and February 2017: 9 patients treated with MTMT and 9 patients treated with AGV implantation. Non-corrected visual acuity (NCVA), intraocular pressure (IOP), endothelial cell density (ECD), hexagonality, coefficient of variation (CV), central corneal thickness (CCT), median survival time of the graft and the presence of epithelial keratopathy were compared between the groups at each time point or between baseline and after treatment of glaucoma in each group. Results There were no significant differences in visual acuity and corneal thickness between the two groups or within each group over time. Both groups showed significant reduction in IOP compared with baseline IOP, and IOP reductions were greater in the AGV group than in the MTMT group (P=0.040). Significant ECD reductions were found in each group between baseline and 6 months (P=0.008 in MTMT group, P=0.015 in AGV group); however, no differences were found between the two groups until 12 months. Significant hexagonality reduction was found in the AGV group between baseline and 12 months (P=0.018). The median survival time showed no significant difference in survival analysis. Conclusions MTMT in penetrating keratoplasty for bullous keratopathy seems to similarly affect endothelial cell density or graft survival when compared with at least 12 month-followed Ahmed glaucoma valve implantation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
