Objective:
5 trials to evaluate the role of steroids and antiviral medication in the treatment and prevention of ocular HSV disaese.
![Page 11: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/11.jpg)
1-Effecacy of oral acyclovir in treating stromal keratitis (non-necrotizing
[disciform] and necrotizing) :
10 weeks course of ACV 400 mg 5x/day or placebo, in addition to topical steroid and trifluridine.
![Page 12: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/12.jpg)
No improvement in:
1 -No. of Rx failures.
2 -time to resolution.
3 -6/12 BCVA.
Oral acyclovir is XXXX in stromal keratitis.
![Page 13: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/13.jpg)
2 -Efficacy of topical corticosteroids in treating stromal keratitis:
10-week tapering course of prednisolone phosphate 8x/day or placebo in addition to topical trifluridine (viroptic)
QID X1/52 then gradual taper.
![Page 14: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/14.jpg)
Topiacl steroid1 -reduce the risk of persistance or
progressive stromal keratitis by 68%.
2 -shortened the duration of keratitis.
Topical steroids are beneficial for the Rx of stromal keratitis.
![Page 15: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/15.jpg)
3 -Efficacy of oral acyclovir in treating iridocyclitis:
10-week course of ACV 400 mg 5x/day or placebo, in addition to topical trifluridine.
![Page 16: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/16.jpg)
Trial was stopped due to slow recruitment.
Rx failure occurred in 50% of the ACV group vs 68% in of the placebo group.
Result were not statistically significant but suggest a possible benefit of oral acyclovir for the Rx of iridocyclitis.
![Page 17: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/17.jpg)
4 -efficacy of oral acyclovir in preventing stromal keratitis or iritis in patients with epithelial keratitis:
3-week course of ACV 400 mg 5x/day or placebo, in addition to topical
trifluridine.
![Page 18: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/18.jpg)
Oral acyclovir did not reduce the risk of stromal keratitis or iritis development in patients with epithelial disease.
11% in ACV group vs 10% in placebo group.
It was more common in those with old Hx of stromal keratitis or iritis( 23% vs 9% in those without previous Hx.
![Page 19: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/19.jpg)
In patients with epithelial keratitis, a 3-week course of oral ACV is XXXX in preventing stromal keratitis or iritis.
![Page 20: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/20.jpg)
5 -efficacy of oral acyclovir in preventing recurrent ocular HSV disease:
12-month course of ACV 400 mg BID or placebo and 6/12 observation period for patients with a Hx of ocular HSV within the preceding year.
![Page 21: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/21.jpg)
Oral acyclovir reduce the risk of recurrent ocular disease during the treatment period (19% vs 32%)
Especialy in in stromal keratitis subset(14% vs 28%).
Non-ocular HSV lower in Rx group(19% vs 36%).
No rebound in the rate of the disaese in 6/12.
![Page 22: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/22.jpg)
Oral acyclovir prophylaxis significantly reduces the risk of recurrent of ocular and orofacial HSV disease, especially in pts with previous
stromal keratitis.
![Page 23: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/23.jpg)
6 -Determinants of recurrent HSV keratitis:
Analyzed the placebo group from the prevention acyclovir trial.
![Page 24: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/24.jpg)
In the placebo group of the previous trial, 18% developed epithelial keratitis and 18% developed stromal keratitis.
Previuos epithelial keratitis did not significantly affect the subsequent risk of epithelial keratitis , and previous stromal keratitis significantly increased the subsequent of stromal keratits (10x).
![Page 25: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/25.jpg)
In patients with ocular HSV disease in the previous year, a history of epithelial keratitis is not a risk factor for recurrent epithelial keratitis , but a history of stromal keratitis increases the risk of subsequent stromal keratitis, and this risk is strongly associated with No. of previous episodes.
![Page 26: Herpetic Eye disease study (HEDS) Presented by : Majed Mohammed Al-Obailan, MD](https://reader036.vdocument.in/reader036/viewer/2022062423/56649ced5503460f949b9881/html5/thumbnails/26.jpg)
