Invasive bacterial eye infections in the neonate range from perforating keratitis to endophthalmitis. Endophthalmitis secondary to Pseudomonas aeruginosa has gained clinical and therapeutic importance since mortality rates are high and prognosis concerning preservation of vision is poor, especially in premature infants. We presented two cases with meningitis, septicemia and P. aeruginosa endophthalmitis. If premature infants develop a sepsis-like picture with cloudy cornea and purulent conjunctivitis, we have to consider the possibility of endophthalmitis and do a full ophthalmologic evaluation. Treatment should be started early and consists of systemic antibiotic therapy, as in septicemia. As P. aeruginosa spreads easily, prompt isolation and strict handwashing are indicated.

We report the frequency and type of infectious ocular complications following orthotopic liver transplantation (OLT) and review diagnostic and therapeutic strategies. During the period September 1988 through November 1994, 684 patients underwent OLT at Mount Sinai Hospital (New York). Nine orthotopic liver transplant patients (1.3%) developed ocular infections: Candida albicans endophthalmitis (2), Aspergillus fumigatus endophthalmitis (1), cytomegalovirus retinitis (4), herpes simplex virus keratitis (1), and varicella-zoster virus panophthalmitis (1). The mean time from OLT to ocular symptoms was 42 days for patients with fungal infections and 128 days for patients with viral infections. Blurred vision was the commonest symptom (five of nine cases). The mean duration of follow-up was 2 years (range, 33 days to 5 years). Permanent loss of vision occurred in three patients, five had improvement in visual acuity, and one died of disseminated aspergillosis 33 days after OLT. Infectious ocular complications following OLT may occur as isolated events or with disseminated disease. Fungal infections occur earlier (mean, 42 days after OLT) than viral infections (mean, 4 months after OLT). The clinical presentation may be atypical; aggressive vitreoretinal procedures and serial examinations may be required to establish the diagnosis. Cytomegalovirus retinitis in orthotopic liver transplant patients may not require life-long maintenance therapy with antiviral agents.

A case of endogenous fungous endophthalmitis with secondary pupillary block glaucoma and corneal invasion requiring penetrating keratoplasty is reported. Initially Paecilomyces lilacinus was isolated from a vitreous and a lens aspirate, but a second vitreous tap revealed Aspergillus fumigatus and P lilacinus. This case highlights the difficulty of diagnosing endogenous fungous endophthalmitis presenting without risk factors and the difficulties of managing such cases using the antifungous agents available. To our knowledge, this is the first case report documenting a progression to stromal keratitis from endogenous endophthalmitis secondary to P lilacinus.

This study was designed to measure the concentration of ofloxacin in aqueous humor after topical, oral and intravenous administration in 50 patients undergoing cataract extraction. In Group 1, ofloxacin 0.3% eyedrops were topically instilled ten times and the aqueous humor concentration was 2.73 +/- 0.88 microg/ml. In Group 2, ofloxacin 0.3% eyedrops were topically instilled six times and the aqueous humor concentration was 0.84 +/- 0.61 microg/ml. Aqueous humor concentration 12 hours after 200 mg oral dose in Group 3, was 0.38 +/- 0.12 microg/ml. In Group 4, patients were given ofloxacin as a single intravenous 200 mg dose and the aqueous humor concentration 2 hours after the end of infusion was 0.45 +/- 0.11 microg/ml. Concentrations were determined by high performance liquid chromatography (HPLC) with fluorescence detection. There was a significant difference between Group 1 and the other groups, but not between Group 2 and Groups 3, 4. It was concluded that ofloxacin penetrates the corneal and the blood-aqueous barriers and can achieve good aqueous levels when given topically and systematically. Ofloxacin can be applied topically for external bacterial infections such as conjunctivitis and keratitis. Systematically administered ofloxacin reached higher levels than the MIC for some bacteria which cause endophthalmitis.

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.

Endophthalmitis after keratotomy is rare and usually occurs soon after surgery. A 56-year-old woman with mild dry-eye symptoms developed keratitis complicated by endophthalmitis 3 years after astigmatic keratotomy (AK). The keratitis lasted for less than 1 day in the upper keratotomy incision. Corneal cultures yielded. Pseudomonas aeruginosa. Keratitis progressed to endophthalmitis 1 day after the detection of keratitis. The inflammation was controlled with intravitreal, subconjunctival, topical, and systemic antibiotics. This case demonstrates the potential risk of endophthalmitis developing very shortly after late keratitis of AK incisions. Vigorous early treatment and close follow-up seem justifiable in any keratitis associated with a keratotomy incision.

Ophthalmological mycosis were seen as blephlitis, conjunctivitis, keratitis, orbititis, endophthalmitis. These dideases were almost hard to diagnose and were rare and refractory to treatment. Among them, keratomycosis was most frequent and relatively refractory to treatment. Orbit mycosis was rare but most refractory to treatment. Almost of them were fatal in our knowledge.

A low nutrient culture medium was used to identify the pathogens in four cases of persisting ocular infection. Bacto R2A agar was used in addition to conventional liquid- and solid-phase media to culture pathogenic bacteria from one case of recurrent keratitis, one case of suture-related keratitis with endophthalmitis and two eyes (two patients) with post-operative endophthalmitis. In each case, a pathogen was identified solely with R2A agar after culture for 6 days. Species isolated were Pseudomonas aeruginosa (one), Propionibacterium acnes (two) and Staphylococcus aureus (one). Antibiotic therapy was tailored to conform to the sensitivity of the cultured organism in each case. The use of Bacto R2A low nutrient agar should be considered in culture negative eyes not showing clinical improvement, or for chronic cases where bacteria may have become adapted to more stringent ocular environments.

Corneal disease is the second most common cause of blindness in tropical countries after cataract. It mainly strikes children who are exposed to numerous infectious agents against which they are unprotected due to the absence of basic health care. In high risk groups, the incidence of childhood corneal-related blindness is more than 20 times higher than in developed countries. There are many causes of corneal-related blindness. Endemic trachoma persists in some areas and inflammatory forms can lead to blindness. Eradication requires instillation of antibiotics in the eye, improvement of sanitary conditions, and campaigns against promiscuity. Xerophthalmia can induce blindness by perforation of the cornea in children with vitamin A deficiency. Measles, herpes simplex keratitis, and corneal ulcer that progresses to bacterial or fungal infections, or to amebic keratitis are also major causes of corneal-related blindness. The incidence of onchocerciasis is decreasing thanks to treatment with ivermectin and programs to control simulium. Neonatal gonococcal ophthalmia and leprosy-associated ocular disease can also lead to blindness. This overview of the various causes illustrates the close correlation between the level of life and living conditions and the occurrence of corneal-related blindness in tropical areas.

We report a case of Pseudomonas keratitis and endophthalmitis after inoculation from the respiratory tract in a mechanically ventilated patient. In these (semi)comatose and more vulnerable patients, colonisation of the upper respiratory tract by Pseudomonas occurs frequently, and this can lead to inoculation of the eyes. Emphasis lies on careful prevention of ocular inoculation and aggressive therapy as soon as keratitis is noticed.
