ABSTRACT
Aim: To study role of intrastromal and intracameral voriconazole combination in recalcitrant fungal
Keratitis.
Materials and Methods: 20 cases of recalcitrant fungal keratitis involving >50% stromal thickness and
not showing good response to oral fluconazole, topical natamycin (5%) and topical voriconazole (1%)
eye drops after 4 weeks of treatment were included in the study after taking informed written consent.
Patients with impending or frank perforation, scleral involvement and endophthalmitis were excluded from
the study. 30 min before the procedure, patient was given Tab acetazolamide 250mg stat to lower the
intraocular pressure (IOP). Then under all aseptic conditions, 50 microgram/0.1 ml dose of intrastromal
and intracameral voriconazole was given with 30G needle. Cases were examined daily for 1 week and then
every week for 4 weeks for monitoring progression of fungal keratitis.
Results: Out of 20 cases, 18 (90%) patients showed significant improvement after 4 weeks. Depending
on the response after 1 week, patients were planned for repeat injection and only 1 patient required >3
injections in whom Lasiodiplodia theobromae was the causative organism. Only 1 patient got worsened
and was ultimately managed with therapeutic keratoplasty.
Conclusion: Intrastromal and intracameral voriconazole combination is an easy procedure with short
learning curve which is highly efficacious and cost effective in recalcitrant fungal keratitis.

1. Introduction
Microbial keratitis possesses a myriad clinical challenge for
ophthalmologists due to its overlapping symptoms, variable
presentation, rapid progression, diagnostic difficulty and
potential complications leading to significant ocular
morbidity. Fungal corneal ulcer is a common yet tenacious
infection causing vision loss in young productive population
of country leading to socioeconomic burden. Depending
on the geographic location, mycotic or fungal keratitis, is
responsible for almost 1-44% cases of microbial keratitis.

cases secondary to increase in contact lens usage, non-
judiciary use of corticosteroids, vegetative trauma and
diabetes mellitus. In developing countries, ocular trauma
by vegetative material and objects contaminated with sand
particles are the most common causes of fungal keratitis
while contact lens (CL) use is the leading cause in developed
countries.
2–4
The contact lens associated microbial keratitis
is secondary to higher chance of adherence to cornea,
wearing lens during sleep, smoking history and unhygienic
contact lens behaviour. In addition to CL wear and
vegetative trauma, ocular surface disease (OSD) is the third
leading cause accounting for almost 29% of cases.
