Introduction:

endogenous endophthalmitis is not frequent but a severe form of ocular inflammation. The source of pathogens is located inside the body, and infection spreads hematogenously.

Objective:

to determine the clinical behavior and endogenous endophthalmitis frequency.

Methods:

a cross-sectional descriptive observational study. Universe understood by 57 eyes with endophthalmitis, 12 of them with endogenous endophthalmitis in Arnaldo Milián Castro Hospital from January 2015 to December 2021.

Results:

the endogenous endophthalmitis represented 21.1% among all endophthalmitis cases. Male gender prevailed; mean age was 68.3 years. 58.3% of patients had best corrected visual acuity of movement of hands at diagnosis. The 58.3% and 33.3% presented diabetes and renal chronic illness respectively. The most common infection sources were catheter infections and pneumonia. The causative agents were predominantly gram positive bacteria and the most common specie was Staphylococcus aureus (33.3%). The control infection was achieved in 10 patients, while the great majority had same or worse best corrected visual acuity at infection resolution than the initial.

Conclusions:

globally, the proportion of endogenous endophthalmitis among all the cases of endophthalmitis shows a tendency toward the increment in the last years. It is presented with poor visual acuity and the more common infection source was catheter infections. The most common isolated specie was Staphylococcus aureus.
