Objectives:
To describe the population of dry eye disease (DED) patients seen at the Philippine General
Hospital (PGH) Dry Eye Clinic, and to compare the diagnosis, type, and severity of DED using Oculus
Keratograph® 5M (Oculus GmbH, Wetzlar, Germany) with clinical diagnosis.
Methodology:
This was a single-center comparative, cross-sectional study. Newly-diagnosed DED patients
were recruited for the dry eye group. A subset of healthy volunteers without DED was also recruited for the
control group. The clinical data for both groups were collected, and the Ocular Surface Disease Index (OSDI)
questionnaire was administered. Standard clinical dry eye testing and Keratograph testing were subsequently
done. The PGH Dry Eye Clinic definitions were used to classify the types of dry eye.
Results:
Eighty (80) eyes of 40 patients per group were examined. For the dry eye group, the mean age and
OSDI scores were significantly higher, while the average tear break up time (TBUT) was significantly lower.
There was no significant difference in average basal secretion test (BST) and Schirmer 1 measurements between
the two groups. 73% had evaporative type dry eye, while 27% had mixed type. Majority of the DED patients
were females of >50 years old with mild evaporative type. Foreign body sensation was the most common
symptom. Overall, there was poor agreement between clinical and Keratograph assessments of diagnosis and
severity among patients in the dry eye group, but there was acceptable agreement when assessment was done
in the control group.
Conclusions
DED patients at the PGH have similar characteristics to reported DED of other Asian
populations. Evaporative or short TBUT type dry eye is the most frequently seen. Further formal validity study
is needed for Oculus Keratograph® 5M to increase the value of its data to be included in routine dry eye
screening.

Objective:
We reported a case of Descemet's membrane detachment (DMD) following ripcord
removal of a Baerveldt shunt in a post-corneal transplant eye, and the interventions done.
Method:
This is a case report
Results:
A 65-year-old male with multiple surgeries (phacoemulsification, two corneal transplants,
and Baerveldt shunt implantation) in the right eye developed increased intraocular pressures,
prompting removal of the intraluminal stent (ripcord) of the shunt. This was complicated by hypotony
and DMD. Ripcord reinsertion and viscoelastic injection were performed to reattach the Descemet's
membrane (DM) but failed. 0.1mL of 14% perfluoropropane (C3F8) gas was injected into the anterior
chamber that successfully reattached the DM with return to pre-operative best-corrected visual acuity
after 1 week.
Conclusion
Injection of an expansive gas (C3F8) was effective in repairing a corneal graft DMD in
an eye with a Baerveldt shunt.
