Initial Therapy of Suppurative Microbial Keratitis in Iraq
Al-Shakarchi Faiz (1)
1. Medical College/ Al-Mustansiriya University
Aim: To provide data based guidelines for selection of an appropriate initial
therapy for management suppurative microbial keratitis (SMK) in Iraq.
Methods: This case series study enrolled patients with clinical signs of
suppurative keratitis suspected to be microbial, presented prospectively at Ibn
Al-Haetham Teaching Eye Hospital from April 2002 through March 2005. Initial
therapy started with ciProfloxacin 0.3% eye- drops. Subsequent treatment
depends on clinical response and cultures’ results.
Results: Out of 396 cases enrolled, positive cultures were obtained in 232
cases (58.6%). The predominating agents isolated were Gram-positive cocci
75 cases (18.9%); Pseudomonas 68 cases (17.2%); and fungi species 74
cases (18.7%). Treatment was initiated with ciProfloxacin eye- drops in 364
cases, and favorable response was recorded in 185 cases (50.8%), addition
of other antimicrobial drugs was required in 56 cases (15.4%), while failure of
treatment was recorded in 123 cases (33.8%).
Conclusion: Use of ciProfloxacin eye drops alone as an initial therapy cannot
cover most of the causative agents of SMK in Iraq. Addition of another drug can
provide a better coverage for the predominating causative agents. The choice
of this additional drug is based on the suspected infecting agent depending on
the regional predisposing factors, and the clinical features.

Clinical Profile and Visual Outcomes in Herpes Zoster Ophthalmicus
Bose Jayeeta (1) , Karki Manisha (1)
1. Venu Eye Institute and Research Center
Purpose: To study clinical profile and visual outcomes in Herpes Zoster
Ophthalmicus (HZO).
Methods: Retrospective review of 18 eyes of 18 patients of HZO between
January to December 2010 was done. Demographics, clinical presentation,
treatment, visual outcomes and systemic associations were noted.
Results: Mean age was 34.5 years. Systemic diseases associated were
Hodgkin’s lymphoma, HIV, Diabetes Mellitus. All patients had rashes on
forehead with tip of nose involvement in 5. Conjunctivitis was present in 7
patients. Corneal involvement included nummular keratitis in 3, superficial
punctate keratitis (SPK) in 8,neurotrophic keratitis in 4 and disciform keratitis
in 1. 5 patients had keratouveitis.16 had presenting visual acuity from 6/6 to
6/60,1HM and1 PL+. Improvement of visual acuity was seen in 17 patients with
exception in the HIV positive patient (who was lost to follow up).
Conclusion: Most common ocular presentation was conjunctivitis and SPK. All
5 patients with keratouveitis had positive Hutchinson’s sign which correlates
with more severe ocular involvement. Improvement of visual acuity was seen
in 17 patients (94.0%). Hence, with appropriate treatment and follow up there
is good visual outcome and minimal complications in HZO patients.

Limbal Autograft After Excision of Primary and Recurrent Pterygium
Doroodgar Farideh (1)
1. Tehran University of Medical Sciences
Purpose: To report the result of limbal autografting in primary and recurrent
pterygium.
Methods: In this case series, all patients who were referred for treatment of
pterygium were included. Indications of surgery included chronic ocular
irritation, impaired or threatened vision, ocular motility problem and cosmetic
reasons. Under subconjunctional anesthesia, pterygium was removed from the
cornea and conjunctiva and a crescent shape limbal tissue from supratemporal
region of the same or the sound eye was then prepared and sutured in the area
of pterygium removal. Postoperatively, topical betamethasone for 4 weeks and
antibiotic for 2 weeks were prescribed.
Results: Two-hundred and three eyes were studied of which, 125 eyes (61.6%)
had primary and 78 eyes (38.4%) had recurrent pterygium. After at least one
year of follow-up, only 9 eyes (4.5%) had recurrence larger than 1 mm. Visual
acuity and refraction improved in 60% of the eyes. No significant complication
occurred except appearance of a fibrous tissue in the donor site which was not
progressive and was covered by the upper lid in all cases.
Conclusions: Surgical removal together with limbal autograft is a safe and
effective method for treatment of primary and recurrent pterygium.

Vascular Tumors of the Iris. They do Exist.

1. Wills Eye Institute
Methods: Iris vascular tumors are believed to be rare or even nonexistent. A
review of patients with diagnosis of iris vascular tumor from the Ocular
Oncology Service, Wills Eye Institute.
Results: There were 53 eyes in 45 patients. Diagnoses included racemose
hemangioma in 41 eyes, cavernous hemangioma in 4 eyes (capillary
hemangioma in 1 eye, varix in 3 eyes, microhemangiomatosis in 6 eyes of 3
patients. Histopathologic confirmation of the diagnosis was available in one eye
with cavernous hemangioma and one eye with varix. Racemose hemangioma
remained stable in all cases and posed no complications. Solitary cavernous
hemangioma was associated with recurrent hyphema and had no systemic
implications. One iris cavernous hemangioma was part of a syndrome with
visceral, brain, and cutaneous cavernous hemangiomas. There were 3
patients with microhemangiomatosis, each of whom had bilateral pupillary
margin involvement and recurrent hyphemas.
Conclusions: Although the existence of iris vascular tumors has been
challenged, there are well documented examples of racemose
hemangioma, cavernous hemangioma, capillary hemangioma, varix, and
microhemangiomatosis. Each has characteristic features and some can
cause hyphema. Although most are solitary lesions confined to the iris, some
(cavernous hemangioma and microhemangiomatosis) may have systemic
associations.
