Polyhexamethylenebiguanide 0.02%) + (Propamidineisethionate 0.1%or Hexamidine 0.1%) eye drops 1drop every 1 hourly hourly during day time, taper according to clinical response

Uncommon.Traum a & soft contact lenses are risk factors
Orbital infections
Orbital cellulitis S.pneumoniae, H.influenzae, M.catarrhalis, S.aureus, Anaerobes,   Group A Streptococcus, Occasionally Gram Negative bacilli post trauma. Cloxacillin 2 gm IV q4h+ Ceftriaxone 2 gm IV q24 hourly+ Metronidazole 1gm IV 12h If Pencillin/Cephalospori n allergy: Vancomycin 1gm iv q12h + levofloxacin 750 mg IV once daily + Metronidazole iv 1gm 24h If MRSA is suspected substitute cloxacillin with Vancomycin
Endophthalmits Bacterial





Post-ocular surgery





S.epidermidis S. aureus, Streptococci, enterococci, Gram- negative bacilli


S.pneumoniae, N.meningitidis, S. aureus, Group B streptococcus, K. pneumoniae

Immediate ophthalmological consultation. Immediate vitrectomy+ intravitreal antibiotics (Inj Vancomycin + Inj ceftazidime)


Intravitreal antibiotics Inj Vancomycin + Inj ceftazidime + Systemic antibiotics Inj Meropenem 1gm iv q8h /Inj Ceftriaxone 2gm iv q24h + Inj Vancomycin 1g iv q12h

Adjuvant systemic antibiotics ( doubtful value in post cataract surgery endophthalmitis)Inj Vancomycin+ Inj Meropenem







Endophthalmitis Mycotic (Fungal) Candida sp, Aspergillus sp. Intavitreal amphotericin B 0.005-0.01 mg in 0.1 ml Systemic therapy: Amphotericin B 0.7-1mg/kg + Flucytosine 25mg/kg qid Liposomal Amphotericin B 3- 5mg/kg Or Voriconazole Duration of treatment 4-6 weeks or longer depending upon clinical response.
