Fungal endophthalmitis in the delayed post operative phase is well documented[1],[2]. The present study deals with eighteen cases of delayed post operative fungal uveitis and endophthalmitis, based on response to various antifungal drugs. Ketoconazole is a drug of the recent past and has been found very effective[3].

  Materials and methods Top

18 clinically diagnosed fungal endophthal­mitis cases were selected for this study. These patients had uncomplicated intracap­sular cataract extraction and good visual recovery (6/9 or 6/6). After 6 weeks or more patients complained of photophobia, lacrima­tion and occasional pain associated with gra­dual diminution of vision. Examination revea­led iridocyclitis with hypopyon in most of the cases and floculent nodules with whitish strands in anterior phase of vitreous. Initially response to local and systemic corticosteroids and antibiotics was obtained but subsequently there was deterioration [Table - 1].

Investigations included swabs from, con­junctival sac and mucosa of the buccal cavity and vagina for culture besides blood and urine cultures. In one case aspirated material from the anterior chamber tap was cultured but it resulted in panophthalmitis. Hence, it was not performed in other patients. Routine haematological & biochemical investigations to rule out diabetes and other systemic disea­ses were also done. The treatment was cate­gorised in three groups.

1. First line treatment was given in 17 cases for 2 to 4 weeks and consisted of 3.5% potassium iodide drops, atropine eye ointment 1% and nysta­tin eye ointment (100000 I.U./g) twice daily. In addition, injection Entodon (hexamethyl diamino isopropanol di-iodide) 400 mg or injection Rano­dine (methyltrioxyethyl iodoamine) was given on alternate days as 10 injections in gradually increasing doses along with collosal iodine 1 table spoonful orally twice a day.

2. Second line treatment was given in patients where no improvement was noted in 4 weeks by supplementing amphotericin B to the first line of treatment as an initial intravenous does of 0.25 mg/kg dissolved in 500ml of 5% dextrose solution in water over 3 to 6 hours. The subsequent daily dose was gradually increased by 0.1 mg/kg body weight until the dose reached 1 mg/kg or the develop­ment of toxic reactions necessitated its withdrawal. The main reactions in the present cases were chills and faver (40°C) in almost every case. In two cases an anaphylaxis resulted and in one case skin rashes were found. 6 patients had decreased renal functions. However, these changes were found to be reversible on the cessation of therapy.

3. Third line treatment consisted of the first line treatment and oral ketocona­zole 400 mg daily after meal for a period of 3 months.

  Assessment of response Top

A. Good Response

i. Control of signs & symptoms of iri­docyclitis i. e. regression of aqueous flare, hypopyon, photophobia and lacri mation.

ii. Regression of signs and symptoms of inflammatory response.

iii. Regression of vitreal haze.

iv. Visual improvement upto the extent of 6/6 or better.

B. Poor Response

If the above were not achieved.

  Observations Top

The results of smear and culture are shown in [Table - 2].

Aspirate from the anterior chamber tap was positive for Candida abicans in one patient and C albicans was grown from blood in 7 and from buccal cavity and vagina in 4 patients each. [Table - 3] shows the response to various threa­peutic protocols. Amphotericin B was helpful in 4 cases, its toxicity was the limiting factor in the remaining 12. Oral ketoconazole was useful in 8 cases. In one patient the eye was lost due to panophthalmitis and one case improved by vitrectomy. The results of hea­matological and biochemical investigations were non contributory.

  Discussions Top

The details of lesions studied in 18 patient in this study brought out a definite clinical picture which was similar to the one pointed out by Fine and Zimmerman[5] and Theodore et at[4]. It is not generally realized that dela­yed infections following cataract extraction are often due to fungi of low pathogenicity.

The relatively slow progressing fungal endo­phthalmitis resembles post operative iridocyl­citis of endogenous origin or low grade bacterial infection.

The long term therapy of antibiotics and corticosteroids is not only ineffectual but may actually promote the growth of fungus and it's extension throughout the vitreous. The outcome of therapy is usually poor by the common antifungal drugs. In this series oral ketoconazole played a key role in comparison to amphotericin B. Till now ketoconazole has been used in experimental situations and its use in clinical setting is a new advance. Much stress has been laid on clinical presentation by various workers because in many instances fungus cannot be isolated. The anterior chamber aspiration which was attempted in our first case was positive but proven delete­rious. Cultures from blood and buccal cavity vagina, though positive in eleven patients in the current study do not establish a definite fungal aetiology for endophthalmitis.

Iodine preparations are known to possess antifungal activity and have been used in the past for keratomycoses Since specific anti­fungal drugs were not freely available for general use of patients, our usual choice fell on iodine preparations for the initial treat­ment. However, it proved useful in only 1 case out of 17. Only 4 cases out of 16 tole­rated the full course of i. v. amphotericin B therapy and improved. In the remaining 12 (75%) cases the drug had to be withdrawn due to side effects, like chills' fever and renal impairment. Since the visual improvement was poor ketoconazole was tried in 11 patient and 8 patients were cured. At present clinical data for ketoconazole treatment of fungal endophthalmitis is not available except the present study and Green et a1[3] have found its usefulness in experimental endogenous Candida endophthalmitis.

Fungal etiology could be established in only one case in which anterior chamber tap aspiration was done. It proved hazardous and was not tried in other cases. Indirect evidence in the form of positive buccal, vaginal and blood cultures were there in half the cases. In rest of the the fungal etiology was presumed on the basis of clinical judgement i. e. deter­mination of signs and symptoms by adminis­tering antibacterial therapy and response to antifungal therapy.

  Summary Top

Eighteen cases of delayed post operative fungal endophthalmitis were studied. Follow up therapy could be done in 17 patients.

Initially, one case responded to 1st-line treatment by local and systemic iodine the­rapy. Subsequently, atmphotericin B was given intravenously and good response was obtained in 4 patients who tolerated it. Oral ketoconazole was successful in 8 out of 11 patients and one case improved with vitrectomy.
