OBJECTIVE

To perform a cost comparison of the 5-year total direct medical costs of iStent inject® W vs. trabeculectomy vs. glaucoma medications for the treatment of primary open-angle glaucoma, with and without phacoemulsification, from the perspective of Filipino patients.

This cost-comparative analysis compared total private sector costs of surgery, post-operative care, and medication usage over 5 years on combined phacoemulsification (combined) or standalone (SA) procedures using iStent inject W, trabeculectomy, and glaucoma medications for the general population and senior citizens/individuals with disabilities. Data, including unit costs and frequencies, were obtained from published literature and local primary research. Scenario analysis consisted of three payment models: 100% out-of-pocket (OOP), coverage from PhilHealth public health insurance, and combined subsidies from both private and PhilHealth insurance.

iStent inject W was less costly than glaucoma medications in all scenarios and patient populations. When compared with trabeculectomy, iStent inject W, was less costly in all patient populations in the OOP scenario, providing savings of 5% for SA procedures and 5% to 6% for combined procedures. It was also less costly as a combined procedure in all populations in the combined private health and PhilHealth insurance scenario, offering 6% savings in the general population and 9% in elderly and disabled patients. However, it was costlier by 1% in the PhilHealth scenario. As an SA procedure, it was costlier vs. trabeculectomy in both populations in the PhilHealth and PhilHealth plus private health insurance scenarios by 18% to 22% and 101% to 109%, respectively. The highest incremental cost for iStent inject W was US$1,662 vs. trabeculectomy as an SA procedure in the general population under the combined private health and PhilHealth insurance scenario.

For Filipino glaucoma patients who are treated in the private sector, iStent inject W, whether combined or as an SA procedure, may be cost-saving compared with glaucoma medications over a 5-year period; however, it may be costlier compared with trabeculectomy depending on health insurance coverage scenarios.

OBJECTIVE

To describe in detail the research agenda-setting process of the Department of Health National Specialty Center for Eye Care with the guidance of the National Institute of Health (NIH) - Department of Clinical Epidemiology.

A research agenda technical working group (TWG) was organized to spearhead the research agenda setting, in collaboration and guidance of the NIH. After identifying relevant internal and external stakeholders, the TWG drafted a contextual map that served as an overarching framework. Research topics were obtained from the stakeholders and the TWG collated, reviewed and summarized prior to ranking them systematically. Each topic was prioritized through a weighted ranking system evaluating its feasibility, public health benefit, and resource/cost requirements. A final en banc session including the stakeholders was held to formalize the approval of the research agenda. An infographic was developed to serve as a visual guide for consultants and trainees in initiating research.

The TWG tallied 85 unique research topics from both the internal and external stakeholders. These topics encompassed a broad range of areas, including epidemiology, surgical, and medical management, health systems research, economic evaluations of interventions, and occupational/environmental factors.

The 2024-2027 research agenda of the Department of Health National Specialty Center for Eye Care was crafted, with the guidance of the NIH Department of Clinical Epidemiology. The goal was to improve the center's research output by aligning it with stakeholders thereby serving as a research benchmarking tool for the local ophthalmology community

OBJECTIVE

To evaluate cone- and rod-specific nonperfusion indices (CPI, RPI) on ultrawide field fluorescein angiography (UWF-FA) and their correlation with diabetic retinopathy (DR) severity and center-involving diabetic macular edema (ciDME).

Sixty-nine eyes of 43 patients with diabetes underwent UWF color photography (UWF-CP), UWF-FA, and macular optical coherence tomography (OCT). DR severity was graded by a masked reader on UWF-CP. UWFFA images were segmented into posterior pole (≤10 mm from fovea), mid-periphery (10–15 mm) and far periphery (>15 mm), and into the macula, within ETDRS fields and extended peripheral fields. Ischemic areas were quantified using ImageJ to calculate nonperfusion index (NPI), CPI, and RPI. ciDME was determined on OCT. Correlations were analyzed using Pearson coefficients (r).

DR severity correlated significantly with global NPI (r = 0.56, p < 0.0001) and across all retinal zones (r = 0.35– 0.57). Both CPI (global: r = 0.56, p < 0.0001; zones: r = 0.42–0.59) and RPI (global: r = 0.55, p < 0.0001; zones: r = 0.40–0.59) showed similar associations. ciDME presence was also correlated with NPI (global: r = 0.40, p = 0.0014; zones: r = 0.42–0.54), CPI (global: r = 0.47, p = 0.0001; zones: r = 0.32–0.55), and RPI (global: r = 0.46, p = 0.0002; zones: r = 0.33–0.54).

Cone- and rod-related retinal nonperfusion strongly correlate with DR severity and ciDME. UWF-FA may help identify high-risk eyes and guide surveillance of ischemia-related progression. Further studies are needed to define ischemic thresholds predictive of vision-threatening complications.

OBJECTIVE

To discuss the clinical presentation and management of idiopathic hypertrophic pachymeningitis that presented with multiple cranial neuropathies.

This is a case report.

A 37-year-old female presented with right-sided headache and ipsilateral cranial nerve (CN) I, II, III, IV, and V deficits which improved with nonsteroidal anti-inflammatory drugs (NSAIDs). Six months later she developed bilateral blurring of vision with pain on eye movement, which progressed to severe bilateral affectation that prompted admission and treatment with high-dose methylprednisolone therapy followed by prolonged oral steroid treatment which was gradually tapered. Recurrence was treated with oral steroids and azathioprine. Diagnostic modalities included an initial cranial contrast computed tomography (CT) scan which was inconclusive; contrast magnetic resonance imaging (MRI) clinched the diagnosis, as well as demonstrated thickening of the optic nerve perineurium. Visual field analysis 30-2 as well as optic nerve head optical coherence tomography (OCT) were used to support the diagnosis and document optic nerve affectation. Biologic testing was used to rule out tuberculosis, syphilis, fungal infection, granulomatosis with polyangiitis, polyarteritis nodosa, and rheumatoid arthritis. The patient had complete vision recovery in the left eye but only partial vision recovery in the right eye.

Pachymeningitis should be a diagnostic consideration in patients with headache and multiple cranial neuropathies. Clinicians should always perform independent evaluation of diagnostic modalities with the patient’s clinical presentation in mind. Pachymeningitis can involve the perineurium through contiguous spread of the lesion and present as optic perineuritis as well, with more insidious progression and lasting deficits than isolated optic perineuritis.

OBJECTIVE

To report a case of lacrimal gland adenoid cystic carcinoma in a 37-year-old female managed with globe-sparing surgery and adjuvant radiotherapy.

This is a case report.

This report details a 37-year-old Filipino female who presented with a 4-month history of right eye pain and non-axial proptosis. Computed tomography (CT) scan showed a right heterogenous extraconal mass with orbital roof remodeling. Lateral orbitotomy with excision biopsy was performed. Final histopathologic diagnosis of adenoid cystic carcinoma of the lacrimal gland was made based on the classic morphology and distinct arrangement of the neoplastic cells. Systemic surveillance revealed absence of metastases. Patient completed adjuvant radiotherapy four months post-operatively. Vision was preserved at 20/20 without signs of tumor recurrence five months post-operatively.

Adenoid cystic carcinoma is an aggressive lacrimal gland malignancy; hence, meticulous examination and high index of suspicion cannot be over-emphasized. Globe-sparing surgery with adjuvant radiotherapy could significantly preserve quality of life.

OBJECTIVE

To present a case of chronic invasive infection rhinosinusitis (CIFRS) complicated by orbital apex syndrome, highlighting the significant diagnostic challenges and delays encountered before establishing the diagnosis.

This is a case report.

This patient is a 65-year-old diabetic female, status post-kidney transplantation with immunosuppressant use presented with headache and sudden painless vision loss and extraocular limitation of the right eye. Magnetic resonance imaging (MRI) revealed a right-sided ill-defined nasopharyngeal mass, with nasopharyngeal carcinoma as the radiologic consideration. Biopsy revealed bacterial and fungal elements. During admission, antibiotics, antifungals, and tumor debulking was done but symptoms persisted. Histopathology showed reactive inflammatory tissue; hence, a short course of intravenous high-dose steroids was given. Overall health declined and patient eventually expired.

This case highlights the importance of maintaining high clinical suspicion for fungal infection despite non-specific radiologic findings in immunocompromised patients with vague, localized symptoms. Prompt recognition and tissue diagnosis are critical for early intervention.

OBJECTIVE

This paper reports a rare presentation of diffuse intraocular inflammation following reversed vaulted multipiece intraocular lens (IOL) implanted in the sulcus of a 7-year-old child.

This is a case report.

A 7-year-old child presented with persistent posterior pole inflammation and optic disc swelling after an improperly placed multipiece intraocular lens in the sulcus. Comprehensive eye and wholebody evaluations were performed with the aid of optical coherence tomography (OCT), magnetic resonance imaging (MRI) and systemic work-up to rule out other causes of uveitis to definitively diagnose the case. The reverse-vaulted lens was eventually explanted. After 1 week post-explantation, the visual acuity improved markedly to 20/100 with the appropriate spectacle prescription. The patient recovered from the ocular inflammation 8 months postoperatively.

This paper reports significant posterior pole inflammation as an uncommon yet potentially visually-disabling consequence of a reverse-vaulted sulcus placement of a multipiece intraocular lens in a child. Careful attention is warranted to ensure proper IOL orientation during implantation, especially in pediatric cataract surgery. Visual rehabilitation is important postoperatively

OBJECTIVE

To describe the first biopsy-proven case of ocular cicatricial pemphigoid (OCP) in a young, Filipino male – an atypical presentation for this disease.

This is a case report.

A 34-year-old healthy Filipino male presented with a 2-year history of intermittent eye redness, foreign body sensation, and tearing. Slit lamp examination revealed symblepharon formation and fornix shortening of both eyes. Excision of symblepharon with ocular surface reconstruction using amniotic membrane graft was performed, and the conjunctival specimen was sent for immunohistochemical analysis. Direct immunofluorescence was performed which confirmed strong linear deposits of IgG and fibrinogen along the basement membrane zone, confirming diagnosis of OCP. Early diagnosis and prompt treatment is even more important in the younger population as OCP tends to progress more rapidly, and is associated with more severe manifestations. If left untreated, OCP may progress to symblepharon or, in severe cases, ankyloblepharon formation.

OCP is a rare, sight-threatening, chronic, autoimmune disease that involves inflammation and cicatrization of the conjunctiva, which typically affects older females and is rarely seen in younger populations. This case report highlights the need for increased awareness among clinicians in the Philippines to consider OCP as a differential diagnosis for chronic conjunctivitis, even in patients outside the typical demographic. Early recognition and confirmatory biopsy are essential to prevent progressive ocular surface scarring and vision-threatening complications.
