Objectives: Staphylococcal blepharitis is a common ocular condition that can cause significant visual morbidities due to corneal complications. This study described the clinical profile of patients with staphylococcal blepharitis seen in a tertiary referral eye center, and determined the frequency and the type of corneal complications, the possible reasons for the delay in diagnosis, and the management prior to the consult. Methods: This study was a single-center, five-year retrospective case series design. The charts of all patients from January 2016 to December 2021 with the diagnosis of staphylococcal blepharitis seen at the External Disease and Cornea Clinic of the Philippine General Hospital that have fulfilled the inclusion and exclusion criteria were included. The data extracted were age, sex, chief complaint, laterality, time of onset of symptoms to consult, previous consults, lid and lid margin findings, conjunctival and corneal findings, pre- and post-treatment uncorrected distance visual acuity, duration of follow-up, and treatments received. Results: Fifty-five (55) charts out of 107 charts with a diagnosis of staphylococcal blepharitis were included. Eighty percent (80%) or 44 patients had bilateral disease. Ninety-nine (99) eyes of 55 patients were analyzed. The median age of the study population was 19 years. Sixty-seven percent (67%) were female, and 33% were male. The mean duration of follow-up at the External Disease and Cornea Clinic was 10.8 ± 14.61 months. Corneal opacity, eye redness, and blurring of vision comprised 70% of the reasons for consult. The mean time from the onset of symptoms to consult was 18.36 ± 25.69 months. Sixty-seven percent (67%) had prior consults elsewhere and 45% came in with a different diagnosis. Seventy-eight (78) eyes had fibrin or crust on the lashes. Fifty percent (50%) of the eyes had concomitant conjunctivitis, while 30% had meibomitis. Fifty-eight percent (58%) of patients had corneal complications. Seventy-two percent (72%) of eyes had bilateral involvement. The median age of patients with corneal complications subgroup was 13 years. The most common corneal complications noted were neovascularization, phlyctenulosis, pannus formation, and marginal infiltrates or ulcers. Twenty-two percent (22%) of all study eyes had visually disabling corneal complications like corneal ulcer, descemetocele, corneal perforation, and corneal scar. Ninety percent (90%) of the patients received standard medical treatment and three patients underwent penetrating keratoplasty. The mean uncorrected distance visual acuity at initial consult of eyes with corneal complication was 20/55 (LogMAR 0.43 ± 0.51) and 20/35 (LogMAR 0.25 ± 0.40) after treatment (p = 0.032). Conclusion Staphylococcal blepharitis was most prevalent among young female patients, and it affected both eyes. Almost all patients manifested the typical lid margin lesions. Nearly 60% of the patients presented with corneal complications and 22% had corneal lesions that were potentially blinding. Close to 50% had delay in treatment due to misdiagnosis.

Objectives: This study described the clinical profile of patients with keratoconus at a single tertiary referral hospital. Methods: This was a single-center, retrospective, cross-sectional study that reviewed medical records of patients diagnosed with keratoconus from January 2015 to August 2022. Data on the clinical profile, intervention, and clinical outcomes were collected from the chart review. Results: Forty (40) patients (79 eyes) were included in the study. Majority (98%) had bilateral disease in which 22 (55.5%) were affected asymmetrically. The mean age was 21 years. Most patients (72.5%) were male. Blurring of vision was the chief complaint in all patients. Atopy was present in 23 patients (57.5%). History of vigorous eye rubbing was present in 31 (77.5%). The mean interval from onset of symptoms to consult was 46.4 ± 33.38 months. The mean pinhole corrected distance visual acuity was 0.47 ± 0.41 (Snellen equivalent of 20/59). The average spherical equivalent was -7.48D ± 6.99D. Corneal protrusion on slit-lamp biomicroscopy was seen in 78 eyes (98.7%). Other findings included Fleischer ring (53.2%), Vogt's striae (19.0%), and apical corneal scar (24.0%). Only one eye (1.3%) had no corneal findings. Thirty-nine eyes (49.3%) were classified as advancedsevere keratoconus. Rigid contact lens was planned for 60 eyes (75.9%). Sixty-two eyes (78.5%) were for collagen cross-linking. Deep anterior lamellar keratoplasty was planned in 10 eyes (12.7%) and penetrating keratoplasty in two eyes (2.5%). Conclusion Keratoconus at the Philippine General Hospital was most frequently seen in young males and asymmetrically affects both eyes. Patients consulted relatively late and presented with a more advanced stage of the disease. History of ocular allergy and eye rubbing were significant risk factors. Improving awareness of this condition must be emphasized to detect keratoconus earlier.

Objective: This paper demonstrated the effectiveness of intrastromal injection of levofloxacin 1.5% ophthalmic solution in the management of recalcitrant Gram-positive bacterial keratitis. Methods: This is a report on two cases of recalcitrant bacterial keratitis encountered at the External Diseases and Cornea Clinic of the Department of Ophthalmology and Visual Sciences at the Philippine General Hospital. Results: Two middle-aged females presented with bacterial keratitis unresponsive to previous antibiotic treatment with impending corneal perforation. The Gram stain of the corneal scraping in the first case revealed Gram-positive cocci, while the second case showed encapsulated Gram-positive bacilli and encapsulated Grampositive cocci in chains. In both cases, repeated intrastromal injections of levofloxacin 1.5% in addition to increasing the frequency of topical levofloxacin 1.5% resulted in marked improvement in visual acuity and resolution of deep stromal infiltrates and hypopyon. Conclusion These cases highlighted the utility of intrastromal levofloxacin 1.5% ophthalmic solution in the management of recalcitrant Gram-positive bacterial keratitis.
