69th AIOC Proceedings, Ahmedabad 2011<br />
2 cases with early presentation had excellent recovery while 3 patients had<br />
moderate recovery due to retinal detachment, extensive RPE atrophy and<br />
glaucomatous cupping.<br />
Oral steroids were given in the dose of 1.5mg/kg body weight and the patients<br />
were continued on a maintenance dose for 1 year. 2 patients were started on<br />
Azathioprine 50mg/day while 1 patient was treated with Methotrexate.<br />
DISCUSSION<br />
Sympathic Ophthalmitis has been reported to occur mainly following trauma.<br />
However it has also been reported to occur following ocular surgery like cataract<br />
surgery, scleral buckling, parsplana vitrectomy 7 , laser photocoagulation Our<br />
study included patients with sympathetic ophthalmitis developing after<br />
penetrating keratoplasty. The indications for keratoplasty were leucomatous<br />
corneal opacity following primary corneal repair (3 patients) and endothelial<br />
decompensation following IOFB removal (2 patients). According to studies,<br />
penetrating keratoplasty for corneal decompensation following IOFB removal<br />
are at high risk for sympathetic ophthalmitis. 8<br />
Dalen Fuchs Spots<br />
The onset of symptoms usually occurs between 3 weeks to 6 months following<br />
surgery. In our study, the symptoms in sympathizing eye occurred between<br />
1-8 years after surgery. The typical presentation of sympathetic ophthalmitis<br />
is a bilateral panuveitis that occurs after ocular<br />
trauma or intraocular surgery. 9 In our study<br />
the sympathizing eye showed mild- moderate<br />
granulomatous anterior uveitis with vitritis<br />
and multifocal choroiditis. Dalen Fuchs spots<br />
with vitritis was present in 1 patient. This is<br />
usually seen in 36%-47% cases. 10<br />
In our study the exciting eye had 1-2 attacks<br />
of endothelial rejection 6-8 months after<br />
corneal grafting. It has been seen that corneal<br />
Figure 1: Dalen Fuchs Spots endothelial rejection does precipitate the<br />
sympathetic ophthalmitis as graft rejection<br />
and sympathetic ophthalmitis have a similar cell- mediated cytotoxic reaction<br />
towards antigens on uveal pigment epithelium. 11<br />
Earlier sympathetic ophthalmitis was considered to be a dreaded disease,<br />
however in our study as well as other recent studies, 1,7 it has been seen that if<br />
treated early and adequately, it has a good visual outcome. Our study stresses<br />
the need for surgeons to fully explain the risks involved to patients undergoing<br />
penetrating keratoplasty in cases with trauma, post vitrectomy or probably<br />
any ocular surgery compromising cornea and which may require penetrating<br />
