A 1-year clinical study was performed on 257 consecutive patients with eye injury admitted in Muhimbili Medical Centre from January 1993 to January 1994. It describes the causes, presenting visual acuity and associated ocular complications, use of traditional eye medicine on the injured eye and lastly the visual outcome. Patients were classified into perforating and non-perforating injury patients. Stones, sticks and metallic objects were the major causes of ocular trauma. The main types of traditional medicines used were plant juices, milk mixed with black powder and pounded roots. The route of application was mainly instillation into the conjunctival sac. Traditional eye medicines were used by 49% of all patients. The main ocular complications presented keratitis, endophthalmitis and panophthalmitis were seen more in patients with a positive history of using traditional eye medicines than those with a negative history. Poor visual outcome was also seen more in patients who used traditional eye medicines than in those who did not use them. The use of traditional medicines on the injured eye is likely to be associated with a very poor visual outcome. It is thus, recommended that intensive health education be provided to create awareness in the community of the dangers of using traditional medicine on injured eyes. It is also recommended to integrate traditional healers into the modern health system in order to use their psychotherapeutically useful abilities and control their practices.

THE CONCLUSIONS WHICH MAY BE DRAWN FROM THE RESULTS OF THE EXPERIMENTS HERE PRESENTED ARE: 1. The cornea of the rabbit is highly sensitive to the action of various injected bacteria. The lesions vary from insignificant, transient changes to severe, destructive panophthalmitis, with fine gradations from the mildest to the violent form of inflammation. Moreover, animals that receive the same organisms show like changes. 2. The varying degree of inflammatory reaction is related to the pathogenicity of the special culture employed; as, for example, is shown by the reactions to Type I pneumococci and to Bacterium granulosis. It is evident that when a microorganism having a certain degree of virulence is used, a lesion of localized vasculonebulous keratitis resembling pannus tenuis or vasculosus of human trachoma can be induced. Thus Bacterium granulosis, Bacillus xerosis, Hemophilus influenzae, Pneumococcus Type II, Streptococcus viridans, and gonococcus can cause the pannus-like corneal changes in the rabbit. Of these organisms, however, only Bacterium granulosis induces early, uncomplicated and enduring keratitic lesions; the others cause first, diffuse keratitis with suppurative lesions; then, as a residual effect, transient, localized, vasculonebulous changes in the cornea. These changes, in contradistinction to the granulosis lesions, are, therefore delayed, complicated, and transient. When, on the other hand, the invasiveness and infecting power of the organisms are low, as is the case with the filtrable, Gram-negative bacillus and the small, Gram-negative bacilli ultimately derived from cases of folliculosis, no marked effect is produced by their intracorneal inoculation. If the pathogenicity of bacteria is high (as shown by Pneumococcus Type I, hemolytic streptococcus, and the remaining bacteria), intracorneal inoculation of the microorganisms leads to serious suppurative or destructive changes. 3. The results of experiments with monkeys indicate that while pannus is not a sequel of experimental trachomatous conjunctivitis, a lesion resembling it follows intracorneal inoculation of Bacterium granulosis. 4. One can infer from these results, therefore, that the stimulus necessary to produce corneal changes in animals, similar to those of trachomatous pannus, is an agent having a definite but extremely low power of invasiveness and infectivity.

A rare case of Bacillus panophthlamitis with extension to the prechiasmatic optic nerve secondary to hematogenous spreading after intravenous drug use is presented. A 27-year-old man with a recent history of trauma to the left eye presented with severe left eye pain following a binge of intravenous drug use. Visual acuity (VA) was LP. On examination he had chemosis, proptosis, elevated intraocular pressure, and a complete hyphema. CT-scan identified preseptal swelling, but no evidence of any posterior extension of the anterior process or orbital fractures. Topical and systemic therapy were initiated. On follow-up clinical examination less than 12 hours after presentation he had signs of a keratitis with worsening ophthalmoplegia and repeat imaging demonstrated posterior extension to the prechiasmatic optic nerve. Shortly after the cornea ruptured with cultures growing Bacillus. The patient underwent enucleation and has had no further progression of infection. To the best of our knowledge, this is the first report of Bacillus panophthalmitis presenting with signs of trauma with posterior extension to the prechiasmatic optic nerve.

The aim of our retrospective study is to report a case series of ocular infections caused by a rare fungus, Scedosporium apiospermum, in a South Indian population. Thirteen cases of culture-positive S. apiospermum infections diagnosed between January 2011 and March 2016 were included in this study. The parameters evaluated were predisposing factors, treatment and final clinical outcome. The most common mode of presentation was keratitis (84.6%) followed by sclerokeratitis (15.3%). The predisposing factors involved were unspecified foreign body injury (30.7%), organic matter injury (15.3%), uncontrolled diabetes (7.6%), and recent manual small-incision cataract surgery (7.6%). Five cases (38.46%) had no predisposing factor. Of the 11 keratitis cases, nine (69.2%) responded well to combination medical therapy while one case (7.6%) required therapeutic keratoplasty. One case was lost to follow-up. Both cases which presented with sclerokeratitis showed no response to medico-surgical treatment progressing to panophthalmitis and evisceration.

We report a case of keratitis caused by a rare fungus Podospora austroamericana. Clinical and microbiological evaluation of the corneal ulcer was done and the treatment outcome was studied. The fungus was grown from the corneal scraping, and it was identified as P. austroamericana based on DNA sequence and analysis of the internal transcribed spacer region. The patient was treated with topical azithromycin, natamycin and voriconazole. Despite maximum medical therapy, the ulcer progressed very rapidly and the patient developed panophthalmitis and evisceration of the eye had to be done. This is the first reported case of keratitis caused by P. austroamericana.

Sphingomonas paucimobilis is a low-virulence gram-negative bacillus known to cause various ocular infections such as endophthalmitis, panophthalmitis and keratitis that are usually associated with an underlying risk factor such as peri-partum or postpartum phase, cataract surgery, contact lens use, neurotrophic keratopathy or ocular trauma. We report a case of spontaneously occurring perforated corneal ulcer caused by the organism in a young man managed by penetrating keratoplasty. The course was followed by endophthalmitis with graft infection culminating in phthisis bulbi despite aggressive medical and surgical management. Along with reporting this case, we also present a review of literature on ocular infections caused by the same organism.
