Nontuberculous Mycobacterial Keratitis

Mycobacterium massiliense Keratitis

“…In another case, loss of corneal sensation was reported while wearing a bandage contact lens during the treatment, and this might have caused the decrease of corneal sensation. 15 In the present case, corneal sensation was revealed to be normal.…”

“…However, these symp-toms could be minimal or mild, because of the relatively low virulence. 14,15 Clinical signs of hyperemia were not as significant as other types of bacterial keratitis. 17 The corneal lesions could be superficial crystalline, white granular opacities, 1 ring infiltrate, and superficial or deep stromal abscess.…”

Clinical and Taxonomic Status of Pathogenic Nonpigmented or Late-Pigmenting Rapidly Growing Mycobacteria

“…Several reports of keratitis due to M. abscessus were described (65,105,132,142,158), and the organism was identified to species. Other authors only identified their isolates as M. chelonae (or the former term M. chelonei), but from the text (susceptibility patterns), we were able to differentiate the organisms as M. abscessus (23,103,108). Additionally, Bullington et al (23) did an extensive review of the literature involving keratitis with nontuberculous mycobacteria from 1965 to 1992.…”

Additionally, Bullington et al (23) did an extensive review of the literature involving keratitis with nontuberculous mycobacteria from 1965 to 1992. He found that 21 of 38 (55%) isolates were M. fortuitum, 16 of 38 (42%) were M. chelonae-abscessus group, and 1 (2%) was identified only as group IV mycobacteria (92).…”

Nontuberculous Mycobacterial Ocular Infections: A Systematic Review of the Literature

“…Clare and Mitchell reported a case of iris root abscess and necrotizing sclerokeratitis in an immunocompetent woman with no apparent risk factors [ 177 ]. Sclerokeratitis was seen after cataract surgery in 4 eyes [ 40 , 123 ], and keratitis leading to endophthalmitis was also seen in 6 eyes after cataract surgery [ 157 , 158 , 161 ] and 2 eyes after penetrating keratoplasty (PKP) [ 133 , 156 ]. In one case of an elderly lady with dry eyes, punctal plug insertion caused secondary upper lid canaliculitis and keratitis [ 29 ].…”
