Methods: In this cross-sectional study, randomly selected
adult participants from Baraangay Bigaa, Cabuyao Laguna
were examined by residents from the JRRMMC Department
of Ophthalmology. Exophthalmometry was performed using
a Hertel’s exophthalmometer (Oculus 35582 Germany). The
exophthalmometry reading to the closest 0.5mm was taken
simultaneously for both eyes and the base recorded to the
nearest 1.0mm. Automated refraction was done using Huvitz
(HRK7000), and axial length was measured using a soft-touch
A-Scan (Accutome USA). Height (cm) and weight (kg) were
measured and BMI computed as kg/m2. Results were analysed
using Minitab Ver16 statistical software.
Results: Total of 173 subjects participated and 3 patients
were excluded, leaving 170 patients for analysis (104
females & 66 males) with mean age of 46.4 years. The mean
exophthalmometric value obtained was 13.8+/- 2.1mm. Females
had significantly lower mean values at 13.5mm +/- 2.0 compared
to 14.2mm+/- 2.2 for males. The relative ocular protrusion value
in our subjects was 2 mm. Gender, BMI, axial length, weight and
base were significantly associated with exophthalmometry values
on bivariate analysis. However, on multivariate analysis, weight
and base measurements were shown to be the only independent
factors affecting the exophthalmometry values.
Conclusion: Exophthalmometry values obtained among Filipino
adults living in Brgy. Bigaa, Cabuyao, Laguna were lower than the
reported values for other population. It is hoped that the values we
obtained will henceforth be a helpful reference value in determing
the presence or absence of absolute exophthalmos in Filipino
patients being evaluated for the presence of orbital disease.

Preseptal Cellulitis, Orbital Cellulitis and Cavernous Sinus
Thrombosis in Jose R. Reyes Memorial Medical Center

Jose R. Reyes Memorial Medical Center, Philippines
Objectives: To determine the clinical patterns of Preseptal
Cellulitis, Orbital Cellulitis and Cavernous Sinus Thrombosis in a
tertiary government hospital in terms of patient profile, organisms
involved, and antibiotic sensitivity patterns.
Methods: Patients diagnosed with Preseptal Cellulitis, Orbital
Cellulitis and Cavernous Sinus Thrombosis seen at Jose R. Reyes
Memorial Medical Center from February 2011-August 2012, with
available Culture and Sensitivity results were included in this case
series. Gram stain, Culture and Sensitivity studies were done
on eye discharge and/ or abscess drainage. All patients with
impression of Orbital Cellulitis underwent Cranial CT Scan with
Orbital cuts. Blood Culture and Sensitivity was also requested for
patients suspected to have Cavernous Sinus Thrombosis.
Results: A total of 112 patients participated in this study with
an age range of 1-75. Mean age at presentation was 26.31.
There were 68 females and 44 males, with female to male
ratio of (1.5:1). 98 patients had Preseptal cellulitis, 14 patients
had Orbital cellulitis. In 8 of these 14 patients, Cavernous Sinus
Thrombosis was diagnosed by neuroimaging studies. Only
22.32% of cultures yielded positive results but the most common
isolate in all 3 conditions was Staphyloccocus Aureus. Sensitivity
tests of Staphyloccocus Aureus isolates showed 100% sensitivity
to Chloramphenicol, Cotrimoxazole, Gentamicin, Tetracycline
and 100% resistant to Oxacillin and Penicillin. All patients with
Preseptal Cellulitis and Orbital Cellulitis resolved with no serious
complication. Three patients diagnosed with Cavernous Sinus
Thrombosis expired while 5 other patients recovered with no
serious complication. Conclusion: Preseptal cellulitis should be
distinguished early from Orbital cellulitis, an extremely serious
infection that can spread posteriorly to the cavernous sinus. CT
scan and Microbial studies aid in the diagnosis and treatment.
Pending availability of laboratory results, the sensitivity patterns
noted in this study can be used as a guide.

Your Common Sore Eyes or Something Endemic?
Charl Marlo A. Jimenez
DOH Eye Center East Avenue Medical Center, Philippines
Objective: To document and report a rare case of an 18 year old
female presenting throughout the course of illness sore eyes and
eventually transforming into a conjunctival mass.
Methods: Case Report Method
Oral Free Papers
Results: A case of an 18 year old female who initially came in
complaining of intermittent eye redness, itchiness and tearing
for the past 3-6 months. She would claim of usage of brazen
of antibiotics and combinations recommended by both general
physicians and ophthalmologists in their locale which would
provide partial relief of symptoms. In lieu the aforementioned
history, loss of vision, diplopia and dizziness would not be
encountered by the patient. Although the persistence of the
aformentioned symptoms and an increasingly obvious growth of
a conjunctival mass led to consult the DOH Eye Center. Patient
was initially treated as ocular tuberculosis, work-up was done,
in order to rule out other diagnoses such as ocular cicatricial
pemphigoid and squamous cell carcinoma. When the patient was
finally cleared for operation, excision biopsy of conjunctival mass
was done with cryotherapy and amnion graft placement on the left
conjunctiva under general anesthesia which she tolerated well.
Conclusion: The specimens were sent of histopathology and
Immunofluorescence studies - which recorded negative for
fibrinogen, C1g, C3c, IgM and IgA. It showed chronic inflammation
whereas lymphoproliferative diseases cannot be ruled out. The
