OBJECTIVE: To determine the range of macular pigment optical density (MPOD) levels in healthy Filipino adults using both the MPS II and the macuscope and to investigate whether age and sex were related to inter-subject variations in MPOD.

METHODS: This was a prospective, cross sectional study of 168 healthy Filipino patients who underwent heterochromic filter photometry to measure macular pigment levels using the MPS II and the macuscope. The MPOD levels were averaged per age group and analyzed as to variations among age and gender.

RESULTS: One hundred thirty (130) and thirty-eight (38) patients underwent MPS II and macuscope testing respectively. The mean MPOD level for MPS II was 0.39(±0.16) and for macuscope 0.27(±0.07). MPOD values were similar across all age groups and gender, but they were lower when measured with the macuscope.

CONCLUSIONS: MPOD levels measured among healthy Filipino adults were lower with the macuscope compared to the MPS II. These differences should take into consideration the differences in apparatus and techniques of measurement.

A study was done to determine if epinephrine 1:600,000 concentration mixed with BSS will have any effect on a patients cardiovascular status during and after cataract surgery. A retrospective study was done on 50 cataract patients from January to June 1999. 0.3ml of epinephrine added to 500cc of BSS were used as the irrigating solution for phacoemulsification. Phacoemulsification using the pre-slice technique under topical anesthesia was performed on all patients. Irrigation and aspiration was done and small amounts of solution to reform the chamber. Patients blood pressure and pulse rates were taken preoperatively, intra-operatively, post-operatively and 24 hrs. post-operatively. Results showed no statistically significant rise in systolic blood pressure and pulse rates. We conclude that epinephrine 1:600,000 mixture in BSS is a safe way of maintaining pupillary dilatation during phacoemulsification. (Author)

Objective: This study evaluated the functional and cosmetic outcomes after bilateral frontalis sling repair using either expanded polytetrafluoroethylene (ePTFE) or silicone rod for unilateral or bilateral severe congenital ptosis with poor levator function. Methods: This was a non-comparative, interventional case series involving 30 patients with unilateral or bilateral severe congenital ptosis who underwent bilateral frontalis sling repair from February 2012 to November 2018. Medical records including pre- and postoperative photographs were reviewed. The functional and cosmetic outcomes were assessed. Results: There were 15 patients with severe congenital ptosis who underwent ePTFE surgery and 15 patients who had silicone rod surgery. Baseline levator function measured was less than 5 mm in all patients. The mean follow-up duration after surgery was 15.6+6.9 months. Satisfactory eyelid contour was observed in all patients (100%). Postoperatively, all had good to excellent primary eyelid position and effective frontalis action on eyelid elevation. Complications included exposure of the silicone sling material after trauma at the brow area (n=1) and recurrence of ptosis (n=2). Conclusion Bilateral frontalis suspension in patients with severe congenital ptosis, whether bilateral or unilateral, resulted in excellent functional and cosmetic outcomes using ePTFE or silicone rod.

OBJECTIVE: To describe the surgical technique of transcanalicular endoscopic lacrimal duct recanalization (TELDR) with balloon dacryoplasty and silicone intubation in patients with complete nasolacrimal duct obstruction and assess their effectivity.

METHODS: Ten lacrimal systems from eight patients diagnosed with complete nasolacrimal duct obstruction (NLDO) underwent TELDR and balloon dacryoplasty with silicone intubation.

RESULTS: All 10 lacrimal systems from eight patients who underwent TELDR and balloon dacryoplasty with silicone intubation had 100% anatomical and functional patency.

CONCLUSION: TELDR and balloon dacryoplasty with silicone intubation represents an alternative, minimally invasive technique in the management of complete nasolacrimal duct obstruction.

Objective: To describe the cytopuncture microbiopsy (CM) technique performed during transcanalicular endoscopic lacrimal duct recanalization (TELDR) in patients with primary acquired nasolacrimal duct obstruction (PANDO) as an alternative to open biopsy, the standard method used in collecting specimen. Methods: This is a noncomparative, interventional case series with histopathologic correlation. Patients diagnosed with complete PANDO who underwent TELDR with balloon dacryoplasty and silicone intubation with CM at University of Santo Tomas Hospital from October 2014 to January 2017 were included. Results: Twenty (20) tissue specimens from the lacrimal sac and nasolacrimal duct were obtained from 18 patients. There were 16 females and 2 males included in the study. Mean age was 57.5 years. All specimens revealed few clusters of benign epithelial cells with few degenerated mononuclear cells and lymphocytes, and singly scattered lymphocytes that are set in fibrinous background. Tissue cytology studies were negative for malignant cells. Conclusion CM is a minimally invasive procedure that offers an alternative to open biopsy technique that can be done routinely during TELDR.
