title: Ocular mycosis at a referral center in Saudi Arabia: A 20-year study.
abstract: OBJECTIVE
  To review the clinical experience of fungal keratitis cases at King Khaled Eye Specialist Hospital (KKESH) in Riyadh, Saudi Arabia.
  
  
  METHODS
  Retrospective observational review and analysis of 124 patient charts with confirmed diagnosis of fungal keratitis between 1984 and 2004.
  
  
  RESULTS
  One hundred and twenty four eyes of 124 patients had proven fungal infection; 101 eyes had fungal keratitis and 23 eyes had fungal endophthalmitis complicating keratitis. Estimated proportion of fungal keratitis and endophthalmitis was 10.3%. Mean age was 55 years with male predominance (79.0%). Commonly associated factors were previous intraocular surgery (38.7%) and trauma (20.9%). Major risk factor for progressing to endophthalmitis was previous intraocular surgery (65.2%), p < 0.001. Initial laboratory results were fungal positive only in 30.6% (p < 0.001). Commonest organisms isolated were Aspergillus spp. (29.8%) followed by Trichophyton sp. (16.1%), then Candida and Fusarium sp. Comparison of both phases of the study showed improvement in the rate of successfully treated cases from 34.6% to 58.3%, and a decline in cases progressing to endophthalmitis from 25.0% to 13.9%. Therapeutic penetrating keratoplasty increased from 26.9% to 73.6% (p < 0.001). Thirteen eyes required enucleation or evisceration.
  
  
  CONCLUSIONS
  In contrast to other studies on fungal keratitis, Aspergillusspp. and Trichophyton sp. were the most commonly isolated fungal pathogens; the former carries the worst prognosis. Risk factors included previous intraocular surgery and trauma. Poor outcome was associated with Aspergillus spp., delayed presentation, previous intraocular surgery and late surgical intervention. This study recommends early surgical intervention to improve the outcome.
