1A 24-year-old soft contact lens wearer presents with excruciating right eye pain out of proportion to clinical signs, photophobia, and blurred vision after rinsing lenses with tap water. Slit-lamp biomicroscopy reveals radial perineural infiltrates and patchy stromal opacities. In vivo confocal microscopy identifies double-walled hyperreflective polygonal cystic structures. What is the first-line topical antimicrobial therapy for this condition?
A.Topical natamycin 5% suspension alone
B.Topical polyhexamethylene biguanide (PHMB 0.02%) or chlorhexidine 0.02%
C.Topical ganciclovir 0.15% gel alone
D.Topical moxifloxacin 0.5% monotherapy
Explanation: The clinical presentation and confocal findings of double-walled polygonal cysts and perineural infiltrates are diagnostic of Acanthamoeba keratitis. First-line therapy requires biguanides (PHMB 0.02% or chlorhexidine 0.02%), often combined with a diamidine (propamidine or hexamidine), which effectively eradicate both active trophozoites and resilient double-walled cyst forms. Early intensive biguanide monotherapy or combination diamidine therapy offers the highest eradication rate and prevents deep stromal encystment.
2A 45-year-old agricultural worker presents with a painful red left eye 5 days after trauma from a tree branch. Slit-lamp examination demonstrates a dense central corneal infiltrate with feathery, indistinct margins, multiple satellite lesions, and a 1.5-mm hypopyon. Corneal scraping reveals septate hyphae. What is the initial topical treatment of choice?
A.Topical natamycin 5% suspension
B.Topical acyclovir 3% ointment
C.Topical dexamethasone 0.1% drops
D.Topical levofloxacin 0.5% drops
Explanation: Topical natamycin 5% suspension is the first-line drug of choice for filamentous fungal keratitis (such as Fusarium and Aspergillus species), which typically presents after vegetative ocular trauma with feathery margins and satellite lesions. The Mycotic Ulcer Treatment Trial I (MUTT I) demonstrated superior visual outcomes, smaller scar size, and lower perforation rates with natamycin compared to voriconazole for filamentous keratitis. Natamycin binds fungal ergosterol to disrupt cell membrane integrity.
3A 32-year-old patient presents with ocular redness, photophobia, and foreign body sensation in the right eye. Slit-lamp examination demonstrates a linear branching epithelial ulcer with terminal bulbs that stains brightly with fluorescein centrally and with rose bengal at the swollen margins. Corneal sensation is reduced. What is the most appropriate management, and which medication is strictly contraindicated?
A.Initiate topical ganciclovir 0.15% gel; topical corticosteroids are strictly contraindicated
B.Initiate topical prednisolone acetate 1%; topical antivirals are contraindicated
C.Initiate topical polymyxin B/trimethoprim; bandage contact lens is contraindicated
D.Initiate topical cyclosporine 0.05%; oral acyclovir is contraindicated
Explanation: The clinical finding of a true dendritic ulcer with terminal bulbs and decreased corneal sensation is diagnostic of Herpes Simplex Virus (HSV) epithelial keratitis. Topical antiviral therapy with ganciclovir 0.15% gel or trifluridine 1% (or oral acyclovir/valacyclovir) is standard first-line management. Topical corticosteroids are strictly contraindicated in active HSV epithelial disease because they suppress local cell-mediated immunity and promote rapid viral replication, transforming the dendrite into an extensive geographic ulcer.
4An 18-year-old male with progressive irregular myopic astigmatism shows inferior corneal steepening on Scheimpflug tomography with maximum keratometry (Kmax) progressing by 1.5 D over 6 months. Slit-lamp examination reveals a Fleischer ring and fine vertical Vogt striae. Corneal pachymetry at the thinnest point is 430 micrometers. What is the definitive treatment to arrest disease progression?
A.Conductive keratoplasty
B.Corneal collagen cross-linking (CXL)
C.Topical latanoprost once daily
D.Deep anterior lamellar keratoplasty
Explanation: Corneal collagen cross-linking (CXL) using riboflavin (vitamin B2) and ultraviolet-A (UVA) irradiation is the only proven modality that halts the progression of keratoconus and corneal ectasia. CXL photochemically induces covalent intra- and interfibrillar cross-links within the stromal collagen, thereby increasing the corneal biomechanical stiffness and stability. Deep anterior lamellar keratoplasty is reserved for advanced scarring or severe thinning where CXL is no longer viable.
5A 66-year-old female presents with bilateral blurred vision that is worse upon waking and improves gradually throughout the day. Slit-lamp examination reveals confluent central endothelial guttata with a 'beaten metal' appearance and early central stromal haze with microcystic epithelial edema. Endothelial cell density on specular microscopy is 650 cells/mm2. What is the surgical procedure of choice that replaces exclusively the diseased host layer while minimizing rejection risk?
A.Deep anterior lamellar keratoplasty (DALK)
B.Descemet membrane endothelial keratoplasty (DMEK)
C.Phototherapeutic keratectomy (PTK)
D.Penetrating keratoplasty (PK)
Explanation: Descemet membrane endothelial keratoplasty (DMEK) selectively replaces only the host Descemet membrane and diseased endothelial monolayer with an isolated donor Descemet-endothelium graft. In Fuchs endothelial corneal dystrophy, DMEK offers faster visual rehabilitation, superior optical quality, and the lowest rate of allograft rejection (<1-2%) compared to full-thickness penetrating keratoplasty or DSAEK. Morning visual blur occurs because overnight eyelid closure prevents corneal surface tear evaporation, worsening endothelial pump-failure edema.
6A 58-year-old patient who underwent penetrating keratoplasty 8 months ago presents with acute redness, photophobia, and blurred vision. Slit-lamp examination demonstrates a linear endothelial inflammatory line consisting of keratic precipitates progressing across the donor graft with localized stromal edema, while the host cornea remains clear. What is this sign called, and what is the immediate first-line management?
A.Khodadoust line; initiate intensive topical prednisolone acetate 1% hourly
B.Arlt line; initiate topical acyclovir five times daily
C.Ferry line; perform emergency repeat penetrating keratoplasty
D.Stocker line; initiate topical antiglaucoma aqueous suppressants
Explanation: A Khodadoust line represents an active endothelial allograft rejection line composed of cytotoxic T-lymphocytes and keratic precipitates migrating across the donor endothelium. Endothelial graft rejection is an ophthalmic emergency; prompt initiation of intensive topical corticosteroids (prednisolone acetate 1% every hour) with or without systemic/subconjunctival steroids can reverse the rejection episode and preserve graft clarity if treated early. Host cornea remains uninvolved because the immune attack is targeted specifically against foreign donor histocompatibility antigens.
7A 52-year-old female with long-standing rheumatoid arthritis presents with severe boring ocular pain and redness. Examination reveals crescent-shaped peripheral corneal stromal thinning and epithelial ulceration at the limbus with adjacent deep scleral inflammation and vascular engorgement. No infectious organism is seen on culture. What is the essential systemic therapy required to arrest tissue melting and reduce systemic vascular mortality?
A.Topical ciprofloxacin 0.3% monotherapy
B.Systemic immunosuppression with corticosteroids and steroid-sparing agents (e.g., methotrexate or cyclophosphamide)
C.Topical ketorolac 0.5% four times daily
D.Corneal collagen cross-linking with hypoosmolar riboflavin
Explanation: Peripheral Ulcerative Keratitis (PUK) associated with rheumatoid arthritis is a manifestation of systemic occlusive vasculitis of the anterior ciliary and episcleral vascular networks. Systemic immunosuppression (high-dose systemic corticosteroids combined with conventional steroid-sparing immunosuppressive agents or biologic anti-TNF/B-cell agents) is mandatory because PUK signals active, lethal systemic vasculitis with significantly increased 10-year systemic mortality if untreated. Topical NSAIDs are strictly contraindicated as they accelerate corneal keratocyte apoptosis and stromal melting.
8A 35-year-old male with a history of a fingernail corneal abrasion 6 months ago presents with sudden, sharp right eye pain and tearing that occurred immediately upon opening his eyes in the morning. Slit-lamp examination reveals a loose area of epithelial elevation and microcysts in the inferior cornea that stains with fluorescein. Which pharmacological combination directly inhibits matrix metalloproteinases (MMPs) to facilitate stable hemidesmosome basement membrane adhesion in recurrent corneal erosion syndrome?
A.Oral doxycycline combined with topical fluorometholone 0.1%
B.Oral ciprofloxacin combined with topical pilocarpine 2%
C.Oral acetazolamide combined with topical timolol 0.5%
D.Oral acyclovir combined with topical atropine 1%
Explanation: Recurrent Corneal Erosion Syndrome (RCES) involves poor adhesion between the corneal epithelial basement membrane and Bowman layer, driven by upregulated matrix metalloproteinases (particularly MMP-9). Oral doxycycline (a tetracycline) and topical mild corticosteroids (such as fluorometholone) synergistically downregulate MMP-9 production and activity, allowing regeneration and stable assembly of anchoring fibrils and hemidesmosomes. Hypertonic sodium chloride 5% ointment is also used to reduce epithelial edema.
9A 70-year-old female presents with chronic bilateral red eyes, trichiasis, progressive shortening of the inferior conjunctival fornices, and fibrous bands bridging the palpebral and bulbar conjunctiva (symblepharon). What is the gold-standard diagnostic investigation, and what classic finding confirms the diagnosis of ocular cicatricial pemphigoid?
A.Conjunctival scraping showing multinucleated giant cells on Tzanck smear
B.Conjunctival biopsy with direct immunofluorescence (DIF) showing linear deposition of IgG, IgA, or C3 along the epithelial basement membrane zone
C.Serum angiotensin-converting enzyme (ACE) and lysozyme elevation
D.Tear film osmolarity testing demonstrating hyperosmolarity > 315 mOsm/L
Explanation: Ocular Cicatricial Pemphigoid (Mucous Membrane Pemphigoid) is a chronic autoimmune type II hypersensitivity disorder characterized by autoantibodies directed against hemidesmosomal antigens (such as BP180/BP230/integrin alpha-6-beta-4) in the epithelial basement membrane zone. The diagnostic gold standard is a full-thickness conjunctival biopsy demonstrating continuous linear deposition of immunoglobulins (IgG, IgA) or complement C3 along the basement membrane zone on direct immunofluorescence (DIF). Systemic immunomodulatory therapy (dapsone, methotrexate, or cyclophosphamide) is required to arrest cicatrization.
10A construction worker presents to the emergency department immediately after liquid drain cleaner (sodium hydroxide, pH 13) splashed into both eyes. Slit-lamp examination shows severe chemosis, epithelial sloughing, and 180 degrees of limbal ischemia. What is the most critical immediate action that must take precedence over all other diagnostic tests?
A.Obtain visual acuity and perform fluorescein angiography
B.Immediate copious ocular irrigation with saline or balanced salt solution until conjunctival pH reaches 7.0 to 7.2
C.Administer topical tetracaine and place bilateral pressure patches
D.Instill topical ciprofloxacin 0.3% and refer to the outpatient cornea clinic
Explanation: Alkali chemical injuries cause rapid liquefactive necrosis and saponification of cell membranes, enabling hydroxyl ions to penetrate deeply into the anterior chamber within seconds to minutes. Immediate copious irrigation with neutral saline, balanced salt solution, or clean water must be instituted at the point of care prior to any formal visual acuity or diagnostic testing, continuing until litmus paper testing confirms a neutral ocular surface pH (7.0-7.2). Secondary medical therapy includes topical ascorbic acid (to support collagen synthesis), topical citrate (to inhibit neutrophil collagenase), and topical steroids early.
