<prompt> Staphylococcal conjunctivitis is associated with all except:Corneal margin infiltrationPhlyctenular conjunctivitisVernal conjunctivitisAll  <response>: C i.e. Vernal conjunctivitis Staphylococcus has been mentioned as a causative organism for bacterial conjunctivitis which can present as Acute PurulentMuco-purulent Conjuntivitis, MembranousPseuo-Membranous Conjunctivitis or Ophthalmia Neonatorum. And, corneal marginal ulcer Q is a complication of Acute Purulent Muco-purulent Conjuntivitis. Apa from this Phlectenular conjunctivitis Q often results from allergic reaction to endogenous staphylococcal proteins, and is often complicated by Muco-purulent Conjuntivitis which is most commonly due to staphylococcus. Vernal and Follicular Conjunctivitis have differen etiologies and are not related to staphylococcus. As for Hordeolum Q ExternalStye i.e. inflammation of Glnds of ZiesMoll Internal i.e. infected Chalazion is most commonly caused by staphylococcus but has not been mentioned as being relate to staphylococcal conjunctivitis. Type of Conjunctivitis Causative agent Example Acute Epidemic - haemorrhagic conjunctivitis Apollo Jai Bangla C. Mnemonic - PACE Picorna virusQ usually Enterovirus 70 Adeno virus 11Q Coxsackie virus A-24Q Enterovirus 70Q Subconjuctival haemorrhage is also seen Infection in Pneumococcus Streptococcus pneumoniaeQ - Koch-Weeks bacillusQ - H. influenzaeQ Head injury, local trauma. Venous congestion due to persistent cough or compression of chest or neck Vicarious mensturationQ Blood dyscrasias eg. leukemia, purpura, haemophilia Hypeension aeriosclerosis Acute membranous conjunctivitis Corynebacterium diphtheriaeQ Streptococcus haemolyticus Virulent typeQ Pseudo-Membranous conjunctivitis Bacterial infection - Corynebacterium diphtheriae low virulenceQ Staphylococcus aureusQ - 13-Hemolytic streptococci - Streptococcus pneumoniae PneumococcusQ - Haemophilus aegyptusQ, H. influenzae Neisseria gonorrhoeaeQ Viral infection Herpes simplex - Adenoviral epidemic keratoconjunctivitis Chemical irritants - Acids, Ammonia, lime - AgNO3, CuSO1 Angular Diplobacillary Conjuctivitis Moraxella lacunataQ, M. axenfeldo and rarely staphylococci Trachoma Chlamydia trachomatis A,B, Ba, CQ Acute Follicular conjunctivitis: - Adult Acute - Inclusion Conjuctivitis or Swimming Pool Conjunctivitis Chlamydia trachomatis serotypes D-KQ - Epidemic Kerato Conjunctivitis Adenovirus serotype 8, 19 sometimes 3, 7 - Pharyngoconjuctival Fever Adenovirus 3, 4, 7 - Acute Herpatic Conjunctivitis - Herpes simplex virus type IQ m.c. - HSV type 2 mostly cause genial infections but sometimes may involve eye - New castle conjunctivitis New castle virus Chronic follicular conjunctivitis - Molluscum contagiosum - Topical preparations eg. Idoxuridine IDU, pilocarpine, eserine, adrenaline, DFP Benignschool folliculosis d t mild infection in school age children Opthalmia neonatorum - Chemical AgNO3 Q 1 2 days - N. gonorrhoea Q - Staphylococcus aureus Q - Streptococcus pneumoniae 2-3 days - Streptococcus hemolyticus - Herpes simplex - II virus - 5-7 days - Chlamydia trachomatis D-K serotype Q Neonatal inclusion conjunctivitis - 7 days Allergic conjunctivitis Delayed type IV hypersensitivity response to endogenous Phlyctenular keratoconjunctivitis - Staphylococcus proteins m.c. cause Q1 - Tuberculous proteins previously considered m.c. cause Q - Moraxella axenfeld bacillus worm infestation - Giant papillary conjunctivitis - Contact lens Q Left out nylon suture - Contact dermoconjunctivitis Topical atropine, penicillin, neomycin, soframycin gentamycin Spring catarrh, hay fever conjunctivitis, atopic keratoconjunctivitis Exogenous allergens as pollen Granulomatous conjunctivitis TB, Sarcoid, Leprosy, Syphilis, Tularemia, Opthalmia-nodosa caterpillar hair conjunctivitis
